My subscribers ask in the comments on which machine I sew and shoot video. I already wrote a review article about my home sewing machine. And now I want to continue my acquaintance and tell you more about how to wind a thread on a bobbin using a sewing machine.
I shot a video and those who wish can watch it:

I’m writing the article more thoughtfully and maybe now I’ll supplement my video with something.
Both for sewing and for winding the bobbin, the thread in an industrial sewing machine is fed from above. For this, a special thread stand is installed on the machine’s desktop.
For winding, a thread tension regulator is installed, since the thread on the bobbin must necessarily be wound with a slight tension. We pass the thread between the plates and adjust this thread tensioner.
We put the bobbin on a special pin winder. The bobbin should sit tight, otherwise it will scroll and will not wind the thread.
During sewing on a machine, the thread is automatically wound on another bobbin. The winding shutdown mechanism is triggered when the bobbin is full. This is for continuous operation of the seamstress in production - a spare bobbin is always wound.
I will consider the option when we start sewing and the bobbin does not have the desired thread color, then you can force the bobbin to be wound.
1. To do this, install the bobbin on the winder.
2. Be sure to pull the thread out of the needle! Otherwise, the threads will become tangled in the shuttle.
3. Be sure to raise the foot of the sewing machine! Otherwise, over time, the teeth (wear out) that promote tissue will fail.
4 . We press the pedal (sewing speed) at full power and thereby reel the bobbin.
With this (forced) method of winding the bobbin, you can not get the bobbin case out of the shuttle. The opinion that during such winding the shuttle device of the machine may go astray - erroneous and unconfirmed. This was checked not only by me, but also by a large working team of seamstresses in production. In the 90s, we had old machines of class 1022, 95, 93, etc., in production, and at one time there was no mechanic. Many seamstresses had a broken winder and therefore they forcibly wrapped bobbins (often about the flywheel) in the manner described above. Not a single sewing machine broke from this! The industrial machine is designed for high speed sewing.
A LITTLE ABOUT LUBRICATION OF THE SEWING MACHINE
In my typewriter, under the head in a special sump, engine oil is poured for lubrication. During sewing, the machine is automatically lubricated. Oil rises through a special tube into the sleeve of the machine and lubricates all the necessary moving parts. Automatic lubrication of the machine occurs at high sewing speeds or high revolutions of the sewing machine. If the machine is used in production (mass sewing), then this happens automatically and imperceptibly. But if a production sewing machine is used in individual sewing, for home, in an atelier, in a workshop - it does not work at all power (due to the low speed of work) and therefore machine oil cannot rise high and lubricate the machine well. In this case, it is even useful sometimes to forcibly wind the bobbin.

CHECK YOUR BOBBINS
The operation of the sewing machine largely depends on the condition of the bobbins. If the sewing machine does not work out, I recommend checking the needle installation on the sewing machine and then carefully looking at your bobbins.
There are two circles on the bobbin, which should be strictly parallel to each other, for this the bobbin needs to be rolled on the surface and carefully examined. If there are bumps, dents, then it is better to throw such a bobbin.
It is necessary to pay attention to the very edge of the circles of the spool. If there are minor notches and damage, then such a bobbin will work, but repair (adjustment) of the shuttle device in the machine is needed. Apparently the needle hits the bobbin (hits) - this should not be! To configure the shuttle, I advise you to call a master mechanic.
TYPES OF BOBBINS
Some industrial sewing machines need bobbins in which the inner hole is completely round (see photo 1) but for my machine you need recessed bobbins.
Stainless Steel Bobbins (2) - these are the best. They are the strongest, wear-resistant. They are solid (solid steel) and perforated. Both species are good. Rust does not appear on them.
Aluminum bobbins (3) - I will not say anything bad about them. Maybe they are not as strong as stainless steel, but if they are handled carefully, they will last a long time. They also do not rust.
Steel bobbins (4) - these are already obsolete. Nowadays, there are practically none on sale. They are strong, with careful handling they serve for years. The disadvantage is that they rust over time.
What will you sew - decide for yourself. That's probably all.

1. Device for winding thread on a bobbin

The device for winding thread on a bobbin is almost the same for all sewing machines, including industrial sewing machines. Of course, there are rare examples with independent adaptation of almost a quarter of the body of the machine, but they are not of interest to us. Such cars are already a museum exhibit. Modern machines do not have an external device for winding the thread, it is hidden in the body, except for the rod to hold the bobbin.
Look, there is a slot on the rod. It’s unlikely that you wondered what it was for. And it also has its meaning. Surely you noticed that some bobbin tightly put on this rod. This is due to the fact that all bobbin manufacturers cannot make a perfectly accurate bobbin inner hole. And in order for any bobbin to pass freely in it, this slot is needed.
Squeeze this rod gently with pliers, or vice versa, unclench it by inserting a screwdriver into the slot. And then the bobbin will dress much easier. Only be careful, otherwise you can break off one of the halves.

The rod has a small “wheel” with a rubber rim, which is pressed against the flat part of the flywheel during winding of the bobbin. That's actually the whole device, it would seem something simpler.

2. The device of the sewing machine winder Seagull

To understand why the reel stops working normally, for example, we took one of the models of sewing machines Chaika. The Seagull is easy to "get" to the device. Just remove the top cover. Turn it over and you will see how the winder is arranged.

3. Why the winder does not wind the thread well

Quite often, the mounting of the device weakens, the rubber rim wears out and sometimes the spring bursts or its edge just pops out of the mount in the form of an opening in the housing. But in any case, you need to check and tighten the screw by welding. Next, inspect the spring, if it popped out, insert it, as shown in this photo.

Now the most difficult case is when the rubber band is so worn out that when you turn on the winder, it simply does not press against the wall of the flywheel. What to do? There is nowhere to buy it, but I don’t want to wind the threads manually or put on a bobbin on an awl. Remove the rubber band and wrap around the groove where it will stand a little thread. This will certainly increase its size, and it will touch the surface of the flywheel, but only for how long?
But most often there is a greasing of the surface of the rubber rim and the surface of the flywheel and the winder slips. Clean both with a cotton swab moistened with cologne or any degreasing liquid, but not with a destroyer.

4. What is the hole on the bobbin wall for?

To minimize the problems with winding the thread on a bobbin, you need to use bobbins designed specifically for your machine. Not all bobbins are interchangeable. There are bobbins for industrial machines, for old-style sewing machines. Modern bobbins, especially those with horizontal shuttle machines, are plastic.
They are lightweight, glide perfectly inside the shuttle course and fit the parameters of the device for winding the thread. Use only those bobbins that are designed for your machine. This will not only improve the quality of loop formation, but also protect your winder from breakage. If you constantly put the bobbin on the spool pin with an effort, then you will certainly expect a quick breakdown of this device. By the way, probably, not everyone knows why you need a hole on one side of the bobbin. It is also used for winding threads.
Insert the ends of the thread inside this hole and start winding, but not at the maximum speed of the sewing machine. Otherwise, the bobbin may jump out of the creel and the winding of the thread on the bobbin will be too tight, which will necessarily affect the quality of the stitch.

5. The main types of bobbins for the sewing machine

A sewing machine bobbin is actually a small metal or plastic spool with a thread wound around it. Such a small and simple detail as a bobbin, it turns out, also has its own “nuances” and can affect the quality of the sewing machine stitch. For example, if the winding of a thread on it was done manually, then the stitch will have uneven tension, etc.
How to rewind, thread and insert the bobbin. What bobbins you need to buy when replacing the bobbins for your machine and much more we will try to explain in the article Bobbins for a sewing machine.


Manual sewing machine
Often, old winders with manual transmission do not work because the winder has a very heavy rubber rim. There is nowhere to buy this part, so the only way to restore it at least temporarily is to wind the thread along the groove of the groove where the rubber ring is worn.


Features of loops "automatic" and "semi-automatic"
We will consider the features of making an automatic buttonhole in this article, which will help you not only learn how to make loops, but also to figure out which particular sewing machine you should buy, which performs loops in automatic or semi-automatic mode.


Reasons for skipping stitches on a sewing machine
There can be many reasons for omissions in the line, but one of them is poor winding of the thread on the bobbin, especially if the thread is wound manually. Its turns are stacked unevenly and too tight, which causes the upper thread to loop from the bottom.


Causes of broken sewing machine needles
The cause of needle breakage may be the curved bobbin wall. Try not to use such bobbins and replace them.


Why does the line loop
This is the most common defect for seagull type sewing machines. This happens, as a rule, for several reasons, one of which is a bad bobbin. Try to buy a new plastic bobbin and replace the "native" one, with needle-punched edges.


Repair of sewing machines Podolsk
If a sewing machine, such as Podolskaya, the lower thread tightly comes out of the bobbin case just when you inserted it into the machine. So you need to replace the bobbin. We recommend you to buy modern plastic bobbins, they rotate more easily and easily in the bobbin case.


Sewing Machine Lubrication
Abundant lubrication of the flywheel can also cause a “breakdown” of the winder. Remove excess grease at the contact area of ​​the rubber ring and wipe with alcohol-containing fluid.


Sewing machine care
Few people pay attention to the device for winding the thread. But it also needs to be periodically lubricated. True, you need to do this very carefully, and only those metal nodes that constantly rotate.

What is a bobbin

A bobbin is a spool of thread or yarn wound during sewing. This detail is presented both in old-style cars ("The Seagull", "Podolsk 132 m"), and in new models ("Dzhanom", "Singer"). Yarn from the main reel (bobbin) is supplied to the bobbin. This procedure occurs automatically. But before filling the bobbin into the machine, you need to make sure that it is suitable for work, otherwise the fiber will break.

Before you wind the thread on the bobbin, you need to find out where it is. As a rule, with modern machines, it is located behind the retractable panel under the needle. But threading in old cars needs a little different.

The bobbin is one of the most important parts of all sewing machines (photo: sweconom.com)

The main purpose of the bobbin is to feed the lower thread. Lower, because the bobbin is usually installed only in units with double sewing. The upper thread must be installed in the needle.

Spool Functions

To thread continuously supplied from the main bobbin, use a bobbin. The fiber feed mechanism can be compared to spinning. This happens as follows: the needle is included in the work, pulling the upper thread along with it. Together, they descend into the zone of action of the lower thread. The upper one forms a loop and captures the lower one. This results in a complete rotation in a circle around the shuttle. This circle allows you to make the loop of the upper thread more voluminous, as well as pass it through the bobbin. That is why both the upper and lower threads are intertwined, and the result is a stitch.

Bobbin location

How to insert a bobbin with thread into a sewing machine with a different type of shuttle? This is one of the most common questions on topic forums. And all because the location of the bobbin in machines with horizontal and vertical shuttle has differences. In the first case, the bobbin is inserted from above and is in the shuttle under a transparent cover. This is the most convenient placement option, so the question of how to thread the bobbin thread into the sewing machine rarely arises. The vertical type of shuttle is relevant for industrial machines or expensive models of household appliances.

In modern machines, bobbins are made of transparent plastic (photo: en.wikipedia.org)

It is also easier to work with a horizontal shuttle because the bobbin is visible through the transparent window of the needle plate. If the thread is almost over, you can always remove and replace the bobbin. The vertical “swinging” shuttle is equipped with old car models - “The Seagull” and “Podolsk”.

For sewing machines with a horizontal hook, the bobbin is inserted into the bobbin case. For machines with a vertical shuttle, the part is inserted from above, directly into the shuttle. Regardless of the type of shuttle, the thread of the bobbin is tucked under the spring plate of the shuttle device or bobbin case.

After the insertion of the thread into the bobbin has taken place, the latter is placed in the socket, and the spool of thread is fixed on the machine body. When the flywheel starts to work, the bobbin and thread spool also begin to rotate. This rotation allows winding yarn.

Spool structure

Modern manufacturers produce standard bobbins made of transparent plastic. In old models of machines metal can be used. Part sizes may vary between machines.

To keep the thread always taut, there is a small screw on the bobbin. So that the thread does not fly out of the bobbin, it is inserted into a special slot.

There is another small detail - the nose, which serves to prevent accidental loss of the bobbin. The nose is attached to a moving panel, which is pressed by a spring mechanism from the sleeve body. Such a mechanism ensures continuous operation in which the thread does not break and does not deform. The state of the bobbin depends on the location of the spout. If the first one changes position, the bobbin may break or fly out during operation. That's why before you take out the bobbin from the slot, you need to bend the nose.

Also, machines have an elongated protrusion on the body. It prevents the rotation of the reel with a bobbin.

The bobbin should not have chips and broken edges

Experienced craftsmen know that as soon as chips are formed on the bobbin, it must be replaced. Even if there were a lot of threads left on it. Otherwise, the thread will stop winding and will break periodically. In the future, this will lead to skipping loops during operation and production defects.

When the thread is tucked into the bobbin, it should fill it evenly and tightly (no, the thread needs to be added). If for some reason the thread is not tucked into the bobbin, although the algorithm of actions was correct, it must be replaced with a new one.

To extend the shelf life of the bobbin, it is better to store it in a special container. The latter allows you to protect the edges of the part from breaks. Industrial storage machines have a special holder on which several bobbins can be strung.

How to refuel a bobbin in different machine models

Each machine has special devices for winding thread on a bobbin.

Winding thread on a bobbin on a Veritas machine. In machines "Podolsk" and "Veritas" for winding thread on a bobbin there is a winder and a tensioner. Чтобы во время процедуры игла не работала, главный вал машины разъединяют с маховым колесом. Левую руку кладут на маховое колесо, предотвращая его вращение. Правой рукой перемещают на себя накатную головку большого фрикционного винта.

В данной модели моталка расположена на крышке рукава. Чтобы намотать нитку на шпульку:

  1. Катушечный стержень перемещают в рабочее положение и надевают на него катушку.
  2. From the latter lead the thread through the tensioner. Moreover, the thread should be located between the screw head and the cap underneath.
  3. In this case, the thread going from the spool to the screw should be at the bottom, and the thread coming out of the tensioner should move up to the bobbin.
  4. Then make two or three turns of thread on the bobbin and put it on the pulley. In this case, the pulley key should fit into the groove of the bobbin.
  5. After that, the pulley with the bobbin is moved towards the flywheel until it stops (to the end of the slot).
  6. The threads on the bobbin are wound until the bobbin rests against the stopper.
  7. After that, the winding will stop and you will need to move the winder pulley towards the head of the machine and remove the bobbin.

Winding bobbins on Brother Modern sewing machines. The algorithm of actions is as follows:

  1. Turn on the sewing machine. Place the bobbin on the shaft of the winder so that the spring on the shaft fits into the bobbin groove.
  2. Press the bobbin to click. It indicates that the bobbin is securely locked.
  3. Slide the bobbin winder shaft to the right until it clicks.
  4. Remove the cap put on the spool pin.
  5. Install the bobbin winding reel on the shaft. Put the spool on the rod so that the first one is placed horizontally and the thread is unwound in front and bottom.
  6. Put the cap of the coil on the rod. At the same time, you need to move it as far as possible to the right.
  7. Holding the bobbin with your right hand, pull the thread with your left and pass it under the thread guide. Next, skip the thread under the thread guide cover from the back to the front.
  8. Hold the thread with your right hand so that its elongated part does not loosen, and with your left hand, stretch the thread under the thread guide plate.
  9. Pull the thread to the right, skip it under the hook of the thread guide to wind the bobbin and wind it counterclockwise between the discs, stretching it as far as possible.
  10. Holding the thread with your left hand through the bobbin winder, with your right hand, wind the end of the fiber clockwise around the bobbin five to six times.
  11. Pass the end of the thread through the guide slot in the saddle of the bobbin winder and pull the thread to the right again to trim it.
  12. Trim the thread. If this is not done with the integrated device, the bobbin may not be wound correctly.
  13. Slide the sewing speed control to the right. Click on the “Start” button. The bobbin starts to rotate and the thread wraps around the bobbin.
  14. When starting the machine or rotating the handwheel after winding the bobbin, there should be a click.

For quality work, it is important that the bobbin always has a sufficient amount of thread and the part is free of chips and cracks. Sometimes defects on the bobbin appear not so much from careless handling as from the wrong choice of thread. During sewing, threads constantly act on plastic. If the fiber is very dense, sometimes it can cause roughness.

The ideal option is thin and elastic threads that easily glide over the surface of the bobbin. Coarse and thick threads are categorically not suitable. Often the machine is used to repair old clothes, so the seamstress uses old cotton threads from the times of the former USSR No. 40 and 30. Such fibers themselves are very coarse, therefore both the surface of the shuttle and the bobbin are injured.
