How to insert thread into an old sewing machine. Threading a sewing machine. Adjusting the bobbin thread tension
Singer brand sewing machines are perfect for beginners because they are easy to use. This applies to both new and old cars. Distinctive feature of this brand - in an automatic yarn feeder. We will tell you how to properly thread a Singer sewing machine.
General instructions
The stitch is an interlacing of two threads - upper and lower. Therefore, both should be threaded correctly, since each of them affects the quality of the seam. Most modern sewing machines have a diagram on the body that tells you how to thread correctly. It’s more difficult with old-style machines; they may differ slightly. If the machine is electric, then you need to thread only with the device turned off to avoid injury to your hands and fingers, in case the machine starts stitching.
First, thread is wound from the main spool onto the bobbin. Many models have a special device that helps do this automatically. To the left of the spool there is a thread guide. The thread is then rotated clockwise around the bobbin winder in front of the holder. Next, you need to thread the thread through the hole in the spool itself from the inside out. If there are holes on both sides, then you can pull the thread through.
On the right side of the body there is a mechanism for bobbin winding. It is worth placing the spool on it, making sure to fix it. The free end of the thread should stick out from the top of the spool. To turn on the winding mode, you need to move the reel to the right. Next, press the pedal and hold the tail for the first windings of thread. If everything is done correctly, the thread will begin to wind, while the flywheel remains motionless. The needle should not sew. As soon as the required amount of thread has been wound, the winding will turn off automatically.
Then you need to cut the thread and remove the bobbin. To do this, the mechanism moves to the left. Until it returns to its original position, the machine will not start sewing. The protruding free end of the thread should be trimmed so that it does not interfere.
Now you can start pulling the upper thread. To do this, the machine is turned off to avoid injury to hands and fingers. By turning the handwheel towards yourself, you should raise the needle up, and then the presser foot.
The coil is installed on a special holder and secured with a cap. If the coil is large, then the wider side of the cap should be directed towards it, and vice versa. To the left of the spool there are clamps through which you need to pull the thread, the second of them is a pre-tension spring. You can pull the thread through the modular compartment and then up through the thread outlet. After this, the thread is pulled through the lower thread guide. Thread the thread into the sewing needle from front to back, stretching it about 10-15 cm.
Some Singer machines are equipped with an automatic filling device. You can use it to thread the needle. To do this, you need to press on it so that it drops as low as possible. It is worth wrapping the thread around the hook to the left of the needle. Holding the thread in front of the needle, draw it around the second small hook on the right from bottom to top.
Now you need to insert the bobbin. To do this, remove the cover and remove the bobbin case; just pull the tip. The spool should be inserted into the cap so that the thread is positioned clockwise. The tail of the thread should be pulled through the slot to the end, the tip should stick out at least 10 cm. Insert the shuttle back into the socket. If the bobbin is positioned horizontally, then a cap is not provided.
Close the lid. Now the bottom thread is pulled up. To do this, you need to make a full revolution of the flywheel so that the needle lowers and rises. The top thread will pull out a loop that needs to be pulled gently. Both threads are pulled under the foot.
Process differences for old and new machines
Older Singer models have hand or foot controls. The latter are more bulky. They are heavy, but reliable, do not depend on electricity and are capable of performing the entire minimum set of functions; in addition, they are excellent at stitching thick fabrics or several layers. There are no special differences between the American Singer and the Soviet one.
In general, threading on older models is not much different from modern ones. Except that not everyone has a tensioner, as a result of which the thread is passed through the thread guide, and then through the eye of the needle. The first step is to select a needle that matches the type of fabric and wind the thread onto the bobbin. Once the thread is threaded, it will become more difficult to wind the bobbin. It is recommended to use one spool to avoid discrepancies in color and thickness.
Manually winding the thread takes a long time and unevenly. You can use the techniques of experienced seamstresses. The coil is put on a needle or thin stick, which you will need to hold.
The bobbin is then moved close to the flywheel. While it is running, the bobbin also begins to rotate and winds the thread. This method requires some skill, since the coil easily flies off the needle.
The second step is to thread the upper thread. The spool is installed on the rod, and the thread guide is brought to its highest position. The thread is pulled through the recess on the front board on the left, then between the washers (plates) of the tension regulator.
If the thread passes tightly between the washers, then they can be tightened, otherwise the thread will break. It can then be pulled up through the hook of the thread take-up spring, if there is one. Again, the thread is pulled up and through the eye of the thread tensioner, lowered down through the hooks of the thread guides or with a hook over the needle, depending on the model, and finally threaded into the needle.
Next, you need to insert the bobbin into the shuttle. On modern Singer sewing machines it often has a convenient horizontal location. On older models, the shuttle is vertical. The bobbin is inserted using a special cap, through a slot through which the thread is pulled. It is ideal to leave a tail of about 10 cm.
The needle must be raised. Now you should place the bobbin in the cap into the slot. The mounting pin should align with the cutout on the plate. If you hear a click, then it is in place, otherwise you need to remove it and carefully reinsert it. While holding the upper thread, you can turn the handwheel towards you one full turn. A loop will appear on the top thread, through which the bottom thread is pulled. There should be 2 threads coming out of the foot.
Older models also have bullet-shaped bobbins. The thread is evenly wound onto it from left to right, then the pointed end of the spool is inserted into the bullet. The tip of the thread must be pulled out through the slot until it stops, go around the sharp corner, pass through the spring and pull the bullets upward until they click. If the bobbin is boat-shaped, then there are holes there that are responsible for thread tension. Than through large quantity The holes the thread will pass through, the stronger the tension will be. The principle of winding and pulling the thread is the same as that of a bullet.
Checking correct filling
Now you need to check that the thread is threaded correctly. To do this, you need to take a small piece or piece of fabric, fold it in half and stitch it. The seam should be smooth. Then you can try sewing more layers, for example, folding the flap again.
The fabric should not bunch up, the stitching should not be interrupted or skipped. Otherwise, this may indicate a breakdown of the machine or the need to adjust the tension. You can also change the stitch pitch. Incorrect threading leads to the stitching slipping, which can ruin appearance fabrics.
Possible mistakes
If the stitching begins to loop and rings form, the thread is not threaded correctly. There is no tension here or it is very weak. You need to check whether the thread guide is working correctly. Poor stitching can also be caused by improper needle placement or mismatch of the needle with the fabric. If the needle does not enter the shuttle, a loop will not form. This is where you need to lower the needle.
The seam may loop due to a malfunction of the spring responsible for tension. To check, you need to lift the foot and pull the thread. Then lower the foot and pull again. You need to do this several times. If tension does not occur, then the tensioner spring is not working well. Too much tension is also bad. If the fabric gathers, the problem is in the shuttle, you need to adjust the tension and then either simply reduce the stitch pitch. Thin fabrics often encounter this problem.

During the classes
1. Organizational moment:
A. Checking the payroll and readiness for the lesson.
B. Reporting the topic of the lesson and recording the topic in the students’ notebooks.
2. Updating knowledge:
10-15 minutes teaching method - game situation.
To check the level of knowledge mastery of the lesson topic: “The structure of a sewing machine”, necessary for mastering the topic of this lesson, students (one by one) are invited to work as a teacher and conduct a quick survey on the slide “Type of a sewing machine”. The “teacher” shows the detail, the students quickly name it and receive a token (1 point) for each correct answer. 5 tokens - 5 points.
3. Study of safety rules when working with CMM.
10 minutes.
The teacher explains the importance and necessity of following safety rules when working on a sewing machine. The teacher goes through each rule and asks problematic questions, starting for example: “Why do you think the light should fall from the front or from the left? “If the girls find it difficult to answer, then she comments herself. Students participate in the conversation. To reinforce this question, it is suggested to say the rules out loud in chorus (slide to help).
Safety rules when working on a sewing machine:
Sh.m. is a device that performs mechanical stitching movements of textile materials and leather for the manufacture of clothing, shoes and other garments. The first sewing machine was invented by the German professor Walter in 1755.
The main advantage of a sewing machine is the speed of sewing and the ability to put sewing production on stream. Sh.m. have become the main technological equipment in the manufacture of clothing.
Modern sewing machines can automatically gather fabric, process buttonholes, perform about 47 stitches and 30 types of lines, stitch leather and various types of fabrics from cambric to drape, and embroider. It is possible to install a double needle in them for sewing with two (even multi-colored) threads at once.
- Do you have a sewing machine at home?
- How is it set in motion? (manual drive, foot drive, electric drive).
- Why did man invent the sewing machine?
- Is it easy to work on it?
- What do you think needs to be done to make the machine work?
To sew on a machine, you need to handle it correctly: be careful, know how to lubricate and adjust the machine. It is also necessary to thread your sewing machine correctly. Now we will get acquainted with the procedure for threading the upper and lower threads in a sewing machine, and in practical work you will learn how to thread both the upper and lower threads.
5. Learning new material:
The teacher, using slide pictures, explains the procedure for threading the top and then the bottom threads in a sewing machine. Students listen to the teacher’s explanations and watch slides (auditory and visual learning of new material). After viewing the slides, the teacher suggests repeating the threading algorithm out loud, showing a video without sound. Students (optional) recite these actions out loud.
Upper threading
The top thread is the thread that runs from the spool to the eye of the needle. Before threading the upper thread, you need to raise the presser foot, then rotate the flywheel to set igloo And thread take-up lever as a last resort top position.
Thread the upper thread as follows:
The spool of thread is placed on the spool pin.
The thread from the spool is passed through the upper thread guide to the upper thread tension regulator. You cannot skip the thread guide because the thread must enter the tension regulator at a certain angle.
Then lay the thread between the tension regulator washers, bending around the regulator from below. Bringing the thread up behind the thread guide hook of the fixed washer of the tension regulator, and then into the eye of the compensation spring and into the eye of the thread take-up.
Pass the thread through the two lower thread guides and thread it into the eye of the needle from the side of the long groove.
After refueling top the threads should be pulled up lower thread from ShK (of course, if it is already installed). For this, holding the end of the thread with your left hand from the eye of the needle, but without pulling the thread, turn the flywheel towards you so that the needle and thread first drops into the hole of the needle plate, grabs the thread coming out of the ShK there, and then rises again to its upper position. After this you need to pull the end of the upper thread and through the hole in the needle plate pull the bottom up. The ends of both threads are pulled by 7-8 cm and lay them down under the presser foot. This completes the preparation of the machine for sewing.
The ShK is designed to place the bobbin with thread inside the shuttle mechanism and ensure free exit of the lower thread from it. The ShK is a metal cup, on the side surface of which there is an oblique slot for thread, and inside there is a spindle on which the bobbin is put.
Refueling ShK. Before you start threading the bobbin, you need to check that the threads on the bobbin are wound evenly and tightly.
Procedure for threading the bobbin thread:
- Take ShK to left hand and insert a bobbin with thread into it: The bobbin should be held so that the thread hangs in the direction opposite to the direction of the oblique slot and so that the end of the thread is located closer to the inner cheek of the bobbin. This makes threading easier.
- Pull the right hand thread through the slanted slot under the pressure spring and then into the small slot at the end of the spring. Make sure that the pressure spring does not move when pulling the thread.
- Pull the end of the thread and make sure that the thread comes out of the bobbin with little effort, the bobbin rotates freely and does not jam.
Installation and removal of the ShK
Before installing the ShK into the shuttle mechanism, you need to perform several preparatory operations.
- Turning the flywheel by hand, set the needle to the highest position so that it does not interfere with installing the ShK.
- Move the slide plate so that you have clear access to the shuttle mechanism.
- Take your foot off the electric drive rheostat pedal and turn off the machine from the network.
Installation of the ShK into the machine is carried out as follows. Take the tucked ShK by the wing of the latch and bend it all the way. In this position, the latch wing must be held constantly with your index finger and thumb left hand so that the bobbin does not fall out of the bobbin. Then put the ShK on the shuttle spindle. In this case, the installation pin must fit into the corresponding cutout of the cover plate of the shuttle mechanism. Then they gradually release the latch wing, while simultaneously pressing the ShK inside until it snaps into place.
When removing the ShK, first deflect the latch wing all the way, and then, constantly holding it large and index fingers left hand, take out the ShK together with the bobbin in it. If the bobbin pops out, do not try to pull it out. It is much easier to reinsert the ShK into place and carefully remove it again along with the bobbin.
6. Practical work “Threading the upper and lower threads:
30 – 35 minutes.
Students are asked to thread the upper and lower threads working in pairs of shifts: A student in a pair threads the threads and a neighbor watches her work, then the neighbor threads. The same work on the other desk. Then one of the pair changes with the partner of the other desk, etc. .Evaluation criteria for the work are given: the first time without errors - 5, the second attempt - 4, the third attempt - 3.
After threading, students write down in a notebook the algorithm for threading the upper thread (thread guide, high tension adjuster washers, compensation spring, eye of the thread take-up lever, thread guide No. 2, 3, eye of the needle from the side of the long groove) and the keywords for threading the lower thread (Thumbs up until it clicks)
- The teacher makes targeted rounds, observes, and records the refueling time of the first and lagging behind.
- Cleaning workplaces by students.
7. Summing up the lesson:
Students sum up the lesson, give themselves a grade for practical work, for a quick survey and additional work (5 tokens - 5 points, 4 - 4, 3 tokens you can get an additional question and answer it).
Next comes the analysis of the most typical errors and writes down homework: Thread the upper and lower threads in the sewing machine at home, mom will mark it in the notebook for the painting, for those girls who do not have a sewing machine at home, you can thread it in the classroom during the week after school.
Using a sewing machine will help you sew things faster and easier, but first you need to learn how to wind the thread on the bobbin and adjust its tension. The bobbin in a sewing machine serves as the source of bobbin thread for stitching. Before you start sewing, you will have to wind the thread on the bobbin. Although all sewing machines are slightly different, the bobbin winding process is generally the same.
Part 1 - Winding the Bobbin
Removing the empty bobbin
Open the shuttle cover. The shuttle compartment is located under the needle. Notice the metal plate through which the sewing machine needle moves to the down position. The shuttle compartment cover should be located on the side of it on the machine body.
Remove the shuttle (if required). Behind the shuttle compartment cover there is a shuttle. It usually looks like a metal cylinder and, depending on your sewing machine model, may need to be removed to remove the bobbin.
Remove the bobbin from the hook. Remove the bobbin from the hook. If the bobbin is secured in the hook by an additional cover, open the cover first.
Find the coil pin. The spool pin is a part of the sewing machine on which the spool of thread is mounted. The pin size corresponds to the size of the hole in the center of the coil itself. Typically the spool pin is located on either the top or side of the sewing machine.
Unwind some thread from the spool. Unwind a little thread from the spool or first release its end from the fixing slot, so that later the thread can easily be unwinded from the spool mounted on the pin. 
Place the coil on the pin. The pin should fit easily into the center hole of the coil.
If the spool has a lock, place it on the pin on top of the spool to prevent it from slipping off.
If the spool pin is located on the top side of the sewing machine, it may not have a locking mechanism.
Pass the end of the thread from the spool through the thread guide. Most sewing machines have a small piece with a hole next to the spool that helps hold the thread in position when winding a bobbin or sewing a stitch. If your sewing machine does not have a thread guide, skip this step. 
Locate the disc thread tensioner. The sewing machine must have a small metal or plastic part around which the thread must be wrapped so that it remains taut. This part is located near the thread guide and looks like a small knob.
Loop the thread once around the disc tensioner. In this case, the thread should bend at an angle with the apex on the tensioner itself. Don't let go of the end of the thread just yet.
Winding the bobbin
Attach the bobbin thread to the bobbin. There should be a small hole on one side of the bobbin. Some items have several such holes at once. Thread the end of the thread through the small hole in the bobbin. The thread only needs to go through one hole on the side of the bobbin.
If there are several holes on the bobbin, use any of them. 
Find a winder. The bobbin winder is a cylindrical pin, similar to a spool pin, but the size of the center hole in the bobbin. Next to the winder pin there will also be a rounded metal or plastic part - a retainer.
Place the bobbin on the winder. Place the bobbin with the center hole against the bobbin winder pin and press down to thread it onto it.
Secure the bobbin in the winder. Depending on the model, slide the bobbin pin toward the rounded latch, or slide the latch toward the bobbin. When the bobbin is securely locked, you will hear a characteristic click.
Hold the end of the thread sticking out of the bobbin. At the very beginning of the process of winding thread onto a bobbin, you need to hold its end (which you previously threaded through the hole in the side of the bobbin) so that the thread does not jump off.
Press down on the sewing machine pedal(or a special button for bobbin winding). If you are using the foot pedal, keep it pressed throughout the bobbin winding process. Maintain a comfortable operating speed for the machine.
To determine the rhythm of work that suits you, you can start by pressing the pedal slowly. But there is no need to wind the bobbin thread slowly.
If the thread does not wind evenly around the bobbin, you may have not hooked it onto the disc thread tensioner correctly. Check the position of the thread. If you think the thread is threaded correctly, still adjust the threading in the thread tensioner to ensure the bobbin is fed evenly.
If the thread catches on the notch on the bobbin, try turning the bobbin over and winding the thread on it in the opposite direction from where the notch is facing.
Wind the thread onto the bobbin. It's not always possible to guess exactly how much bobbin thread you'll need, so it's wise to wind the entire bobbin each time so you don't accidentally run out of thread in the middle of a project.
The bobbin is considered full when the thread on it reaches the outer edges of the bobbin. If you continue to wind the bobbin past this point, it may not fit into the hook or may stop rotating in it.
Cut the thread. Take scissors to separate the spool and bobbin connected by a common thread. Immediately hold the end of the bobbin thread so that it does not begin to unwind.
Move the winder to its original position (if it does not happen automatically). When the winder returns to its original position, you will hear a click.
Remove the bobbin from the winder. Now the bobbin with the thread already wound on it is ready for further use.
Part 2 - Threading the sewing machine
We have already looked at how thread winding works in classic machines, now we will look at how to thread the thread and how to wind the bobbin in more modern versions.
Place the spool of thread on the spool pin. Place the spool of thread on the spool pin located on the top of the sewing machine. The spool should be positioned so that the thread unwinds from it counterclockwise.
Check the top of the sewing machine for a threading pattern before threading bobbin thread. Some models of sewing machines display a small diagram on top of where the thread should go from the spool for further threading of the bobbin.
Pull the thread from the spool. Pull the bobbin thread to unwind it a little and pass it through the disc thread tensioner on top of the sewing machine. Typically this tensioner is located at the opposite end of the top side of the sewing machine from the spool, approximately above the needle. The disc tensioner may also have a small wire attached to it to help hold the thread in place.
Attach the end of the bobbin thread to the bobbin. Next, you need to thread the end of the bobbin thread into one of the holes on the bobbin, and then wind several turns of thread onto the bobbin axis for its primary fixation.
Be aware that fabric and craft stores can sometimes buy pre-threaded bobbins if you don't want to bother with winding the bobbins yourself.
Place the bobbin on the pin. The small bobbin winder pin is also usually located on top of the sewing machine near the spool pin. Place the bobbin on this pin. Then slide the pin to the right or slide the lock located next to it to the left (depending on the design of the sewing machine) to lock the bobbin in the winding position.
When the bobbin locks, you should hear a slight click when you move the pin or lock into the desired position.
Start winding the bobbin. Start winding the bobbin for a few seconds by pressing the sewing machine pedal or the special winding button (if your sewing machine has one). This will ensure that the thread is securely fixed to the bobbin. After a few turns of the bobbin, you can stop to trim the end of the thread sticking out of its hole.
Finish winding. Gently press your foot down on the sewing machine pedal or press the winder button again to completely fill the bobbin with thread. Winding may stop automatically when the bobbin is full, but if it does not, stop it yourself when the thread is almost flush with the outer edge of the bobbin.
Remove the bobbin from the pin. Slide the bobbin winder pin or lock to its original position (if it does not happen automatically) and remove the bobbin. The spool and bobbin will still be connected by thread, so take your scissors and cut it so that there is a tail of about 5-7.5 cm long on the bobbin.
Once the bobbin is ready, you can start threading the sewing machine.
Upper threading
Install the spool onto the spool pin. The spool pin will be located at the top right of the sewing machine. It is noticeably larger in size than the other pin intended for bobbin winding, which may also be nearby. Place the spool on the pin and unwind a little thread from it.
The spool can behave more steadily when sewing if you set it so that the thread comes out from behind it when you look at it from the front.
If your sewing machine has a top threading pattern, pay attention to the marking on the location of the spool pin and the direction in which the thread unwinds from the spool.
Hook the thread onto the thread guide. Pull the thread from the spool mounted on top of the sewing machine. Pull the thread to the left along the top of the sewing machine and pass it through the thread guide located there. The thread guide is a metal or plastic part protruding from the top, onto which the thread clings before going down.
Be sure to pass the thread behind the thread guide and not in front of it, so that it can then easily go down the front of the sewing machine and then make its U-shaped route there.
Most likely, the machine will have a diagram for passing the thread through this section.
Pull the thread down to hook it onto the disc tensioner. Following the directions of the arrows on the sewing machine body, pull the thread from the thread guide towards you. Next, you will need to hook it to the disc tensioner located lower in the front of the sewing machine body, and then lift the thread up again and pass it through or along the second thread guide (often represented by a slot). As a result, the front thread forms a letter “U” extended upward.
Pass the thread through the thread take-up. Once the thread has formed a “U” shape, you will need to hook the thread or pass it through the hole in the thread take-up located at the top, and then lower it down towards the needle mechanism. The thread take-up is a metal piece that protrudes from the body of the sewing machine from the slot of the second thread guide. The thread take-up has a special hole or hook through which the thread must pass. When you complete this step, the thread will already draw a large S-shaped zigzag on the front of the sewing machine body.
Thread the sewing machine needle. Pull the thread towards the needle. Hook the thread onto the last thread guide above the needle (if provided by the design of the sewing machine), and then thread the thread into a small eye of the needle and, on the opposite side, pull out a tail about 10 cm long. Then pass the tail of the thread under the foot of the sewing machine through the slot in its front part .
Now the top thread of the sewing machine is completely threaded, all you need to do is thread the bottom thread before you can start sewing.
Threading the bobbin thread
Remove the cover from the shuttle mechanism. The shuttle mechanism is usually hidden under a cover, which is located on the platform of the sewing machine body directly in front of the needle or slightly to the side of it. Find this cover and open it. Inside you will see a shuttle into which you will need to insert and thread the bobbin.
The shuttle cover should be easy to remove. If you can't get it off, check your sewing machine manual to make sure you are actually trying to open the hook mechanism.
In some models of sewing machines, there may be another protective cover on the shuttle itself. It will also need to be removed to get to the place where the bobbin is inserted. 
Unwind about 10 cm of thread from the bobbin. Before inserting the bobbin into the hook, you need to unwind about 10 cm of thread from it. This should be enough so that the upper thread can pick up and pull up the lower thread when you turn the handwheel of the sewing machine.
Make sure you unwind the tail from the bobbin long enough so that you can pick it up later with the upper thread. Ten centimeters is usually more than enough, while a tail of the lower thread that is too short will simply not allow it to be picked up.
Insert the bobbin into the hook located under the needle. Check the pattern for threading the bobbin into the hook, reflected on the cover of the shuttle mechanism, so as not to make a mistake with the direction of the bobbin thread. Thread the bobbin into the hook according to the instructions in the diagram.
If you pull the bobbin tail to the right, the bobbin should begin to rotate in the hook without any difficulty.
Close the hook mechanism when you insert the bobbin into it. If the shuttle hook has an additional cover, be sure to replace that too.
Bring the bottom thread up. While the lower bobbin thread is still under the needle plate. To bring it up through the needle plate hole, place your right hand on the handwheel located on the right side sewing machine, and hold the tip of the upper thread with your left hand. Turn the handwheel toward you several times until the upper thread pulls the bobbin thread loop over itself. Grasp the loop and pull out the end of the bottom thread, about 10 cm long.
If the bobbin thread does not pick up, check the bobbin bobbin to double-check that the thread is unwinding from the bobbin in the correct direction and is moving smoothly. If the thread is difficult to thread, there may be too much thread wound on the bobbin, in which case you will need to unwind the excess thread from it.
Please check your sewing machine's owner's manual as some steps may differ from those in this article.
If you have lost your owner's manual and are still unsure about how to wind the bobbin correctly, contact your sewing machine or fabric store for advice. One of the employees will likely be familiar with how various sewing machines work and will be able to point you in the right direction.
When shopping for bobbins, bring a note with the make and model of your sewing machine so you can buy the right parts for you, as bobbins vary.
Warnings:
Moving parts of the sewing machine can cause injury. Become familiar with these parts and keep your hands and other objects away from them. This is especially true when it comes to not putting your fingers under the needle.
Do not try to adjust the bobbin thread tension yourself. Usually it is set correctly right away, so to adjust the stitching it is better to adjust the tension of the upper thread.
If you have a lot of experience with a sewing machine, don't be afraid to adjust the bobbin thread tension. The ability to adjust the tension will allow you to easily work with many various types thread
Before you start using the sewing machine, you need to carefully study the instructions and learn how to thread the machine. Threading each machine involves using two threads at the same time - upper and lower. The lower thread is fed from a spool located in the bobbin, and the upper thread is installed in its designated place and, through simple manipulations, is threaded into the eye of the machine needle. Regardless of the model of the machine - manual, foot, electric - it is necessary to exercise extreme caution both during the process of threading the machine and at the time of sewing.
1. To make it easier for a novice seamstress to understand the threading scheme, we suggest that you first familiarize yourself with the diagram of the sewing machine.
2. Wind the thread onto the bobbin, and at the same time take the spool for the upper thread. Then we put the spool on the top pin (a special place for the spool of thread is always located in the same place).
3. Thread the upper thread: as a rule, each machine has instructions, most often on the body itself. The top thread is the one that comes from the spool and is pulled into the eye of the needle. Immediately before threading, be sure to raise the foot and place the needle in its highest position.
4. We carefully check the thread tension: modern machines have a regulator, and there are also several positions that affect the final tension force.
5. Carefully check that all steps of threading the upper thread have been completed correctly. Let's start filling the bottom one, for which we turn off the drive or the moss wheel. We insert the bobbin into place (there may be differences here depending on the model of the machine). Once completed, you need to turn on the wheel and spin it several times until there is enough thread on the bobbin.
6. Insert the bobbin case into the shuttle device, while the bobbin pin should align with the slot of the shuttle device. When installed correctly, a characteristic click should be heard.
7. We bring the thread through the hole in the sliding plate and close it. Now all that remains is to connect both threads and bring them back under the foot.
8. The general refueling scheme looks like this:
Now you know how to thread a sewing machine and after carefully studying all the steps, you can easily cope with this task. To check, turn the flywheel a little; after lowering and raising the needle from the hole in the plate, there should be a loop on the upper thread from the lower one. As you can see, threading a sewing machine is not an easy task; it requires concentration and strict consistency. But after doing this procedure several times, you will be able to perform familiar actions in a very short time.
Do you have a sewing machine? This is a very valuable acquisition. Even in the most difficult times, the said creation of human genius fed and supported not only tailors, but also their families. Now you have to sit down at the sewing machine for the first time. Fears aside. You will succeed.
First you need to learn how to thread the machine. It depends on whether she will sew for you. This procedure consists of 3 parts: you must first fill the bobbin with thread, then thread the upper thread into the needle, then the lower thread. The top one usually fits in easier; the bottom one will require a bit of fiddling.
Rules for threading
Before operating the sewing machine, we first recommend that you read the instructions on how to thread correctly. Each machine needs to be threaded with 2 threads at a time. The bottom one is fed from the bobbin. And the upper one originates on a coil mounted on a special holder on the body, and then, snaking, it moves along this body and goes down to the needle, where it connects with the lower one.
Threading the thread, regardless of the model of your machine, should be done in stages. We will try to help you with this.
Filling the bobbin
Is our bobbin empty? It needs to be filled with threads of the color and size you need.
- To do this, take the coil you have chosen and put it on the holder on the body. To prevent it from falling off, we secure it with a cap.
- Then we take out the bobbin, thread the thread into the tiny hole on it and wind it 3-4 times by hand. Then we put the bobbin on the lever and move it to the right.
- We pass the thread from the spool through 2 holders. When you press the “start” button (in new models) or the machine pedal, the bobbin will begin to quickly wind the thread. After 30 seconds, the bobbin is full.
- We remove it from the holder, tear off the thread or cut it off from the spool. The final touch remains - insert the bobbin into the hook at the bottom of the machine under the platform with the needle.
Insert the bobbin into the shuttle
Open the shuttle cover and insert the bobbin into it. The thread with its free end should be on the left, closer to you. Now about the same thing - in more detail. The shuttle is designed with 2 grooves through which the thread must be pulled.
- First, we pull the thread through the 1st groove so that it faces “towards you”.
- And then - through the 2nd groove, so that the thread goes “away from itself”.
- It should be remembered that the thread in the bobbin case should not be threaded too tightly; it needs a certain tension.
- Close the shuttle cover. The bottom thread should only peek out from under the lid for the time being.
Threading the top thread
We put the spool with the thread we need on the lower holder on the body. Now we have to finish it and connect it with the already prepared thread in the shuttle. Supporting devices have been prepared for our top thread so that it does not slip, but moves forward smoothly and cheerfully.
- First we pass it through the tensioner, then through the lever under it. In modern machines, to the left of the needle there is another lever - for a more convenient needle threader. With or without his help, we thread the thread into the eye of the needle.
- And finally, by pressing the button (in the automatic model) or using your fingers, pull the bottom thread up. For this purpose, we lower and raise the needle once or twice with the thread already threaded, and then the upper thread will hook and pull the lower one with the help of a loop.
Threading a sewing machine is not that easy, but it’s not that difficult either. This requires a basic skill, which is developed after several refuelings. A beginner seamstress or tailor will need intelligence, responsibility and strict adherence to instructions. After doing this operation 3-4 times, you will begin to do it mechanically, without turning on your brain.
To consolidate the topic, we will give a few more recommendations.
- Don't forget to read the machine's instruction manual.
- View the schematic drawing of threading, which the manufacturer has placed on the sewing machine in the form of arrows especially for your convenience.
- Be sure to disconnect the machine from the power source when threading.
