Proper refueling bobbins, shuttle and lower threads in a sewing machine
People increasingly prefer sewing machines and depart from manual sewing. The latter is often used by professional masters only in cases where you need to flash tight material with a sew or thick needle. Aggregates for sewing consist of a large number of moving parts, so you need to know how to care for them, so that the work process delivers maximum pleasure. Among such elements there is an essential element. a bobbin. In this material it will be told how to fill the bobbin to the sewing machine and that it is generally.
A bobbin for a sewing machine is a miniature bobbin on which the thread is wound to create a lower line. Accordingly, the thread used in it is called the bottom. The winding process is performed in automatic mode by the device. To do this, you just need to fix the bobbin at the top of the sewing machine. Next, the bobbin is inserted into a special compartment. a bobbin cap, which is put on the shuttle of horizontal or vertical type.
The bobbin and the bobbin cap are one of the main parts of the sewing machine. They should always be in good condition. The surface of the cap must be smooth, because even a small flaw is able to twist the line and lead to the wrong operation: from the passage of stitches to the cliff of the lower thread.
Important! During sewing, the upper thread pulls the bottom, located in the bobbin. After their interlacing and the stitch is formed. The tension of the thread depends on the weight of the bobbin, as well as from the manufacturing material. Plastics will move faster than metal.
It is worth saying that the sewing bobs, like a bunk cap, differ significantly from each other. Almost every typewriter only those bobs and caps that produce equipment manufacturer. Different bobbins not only in their radius and width, but also by manufacturing material. Usually make metal and transparent plastic parts.
Such elements are intended for several types of shuttles: vertical swing and vertical double entrance. Naturally, a metal bolt is heavier than a plastic element, but it will have increased strength and wear resistance.
Note! Metal details of this type are considered the most reliable. They are distributed not only in household sewing machines, but also the production units of the class “Economy” or “Premium”.
Plastic boutwork most often used by Japanese sewing appliances with horizontal shuttle. Usually, the machines with a horizontally oriented shuttle have transparent needle plates through which the thread can be seen. Bread in such devices is also made plastic and transparent. Plus such a detail in its weight, and minus. in strength.
How to fill the thread into any sewing machine
Unlike overlock, the sewing machine has two types of filament. it is the upper and lower. And each of them is regulated separately, but about it a little later. If you look carefully at your typewriter, you will see that there is a metal rod on its body from above. this is a coil holder with threads. Usually they have an adjustable structure if you put a sewing machine after sewing to a storage place, for example, in the closet, then the rod must be lowered down. And when working, respectively raise up.
Next to the coil rod is another rod, but already with a hole on the housing. this is a filamentaker. It is needed so that when sewing and rotating the coil, the thread is not confused.
Also on the housing of the sewing machine to facilitate the thread product process, there are notation with numbers. In the future, you can look at these prompts and remember how to make a dressing machine. So let’s begin. First you need to take the coil of the right color.
In the 19th century, Georg Naidlinger. the European Agent of the firm Zinger, proposed to establish the production of sewing machines in Russia. Plant under the guidance of Walter Frank Dixon built quickly. Provincial Podolsk had a lot of cheap land and labor. German concern, expanding the production of sewing equipment, in 1902 opened in Podolsk factory.
By 1913, the Podolsk enterprise produced 600,000 cars per year. It’s 2500 products per day. They were sold throughout the Russian Empire, did not give way to the quality of imported devices, for poor people implemented in installments. On the territory of the country a network of branded shops was deployed.
After the revolution, the company was nationalized, but, despite the rupture of relations with the “Head Office”, the production of equipment did not stop. Only 77 years later, in 1994, Zinger resumed cooperation with Podolsky representation.
The most common in the apparatus is a simple machine with a manual drive, sometimes with a foot pedal; For a long time was almost the only driving machine in Russia. Until now, in school workshops you can see such copies with manual drive.
Advantages: According to power characteristics, it is not inferior to modern electronic analogues. Thick fabrics are stitched carefully and reliably.
Disadvantages: Limited Assortment of Action. Can be engaged only by the simplest operations.
The model specializes in working with synthetic, silk, flax and wool.
Also “Podolsk-132” can embroider and dust. It is possible to use both single-lung and double-barrel needles.
List of permitted threads:
- 1 tex x 3 (0);
- 16.5 tex xs (0);
- 13 tex x 3 (0);
- 10 tex x 3 (0);
- 7T5 Tex X 3 (No., 80) GOST 6309-73;
- Nuts made of natural twist silk 5 according to GOST 22665-77
Advantages: Reliable, durable, easy to learn;
Disadvantages: severe, takes a lot of space.
A simple aggregate of steel parts. almost never breaks. Like its predecessor (132nd), this model sews and straight string, and zigzag. From the previous model is insignificant:
Podolsk 142 requires only periodic care and lubrication; In stock Device for winding thread.
Advantages: Reliability, High Build Quality, Durability.
If an instance of the typewriter got into your hands (and others now do not find. only if someone carefully kept her several decades in perfect conditions), first of all, you need:
- Check the shuttle stroke (cleaning the compartment from the eyes is just a necessary measure);
- Remove all moving elements that it turns out (including the needle plate and the main cover);
- A rag or a special brush (with soft metal bristles) to walk along the tooths, rotation grooves (where the most dirt is copied due to oil / solidol) and through a bunch cap;
- No matter how anecdotically sounded, but try to make it so that after the reverse assembly of the machine you do not have extra details. The peculiarity of the products of the Podolsk factory is that it is simply no extra detail.
How to make a needle
Many novice seamstres can “cut off” at this moment, and calculate that the machine is irrevocably broken and is not subject to repair. it often turns out that it is simply incorrectly set to the needle.
The schematic figure shows how everything should look like:
Lubrication of central nodes
- Do not forget about hard-to-reach places. connecting joints, poor grooves, hinges. Main nodes. shaft, drive, almost always have holes in which can drop special oil. GOST for oils is described in the instructions;
- External, visible part of the device also needs lubricant, like internal. it greatly engraves the appearance of the machine. Try not to grind the places where the fabric will be later, so that it does not have to throw it out due to fat spots.

Adjusting Podolsk. Features of the needle product
Periodically, when working with a coarse cloth, the following happens. due to the specifics of the material, the needle product shifts up and the sewing line begins to interrupt. To prevent it, you need to change the needle position. This is done as follows:
- The adjusting screw fastening screw is inside the front compartment housing, and access to it is possible only through a special hole. You will not see the screw, but in his grooves to the touch, you can put a short flat screwdriver. The screw is on the right side of the typewriter, and it only needs to weaken, but in no case to unscrew completely! Insert it back will be much more difficult.
- Turn the flywheel Move the shuttle’s nose to the needle and adjust the position of the needle so that at the time of the nose of the shuttle and needle, it passed the bottom edge above the needle’s ear of 1.5. 1.8 mm. After installing this position, tighten the screw of the needle.
The bottom thread is confused if the lower thread is broken, first unite the shuttle stroke. Perhaps you will find there such a picture.
Incorrectly filled bobbing rarely who pays attention to refueling thread from the bobbin. The scil machine is always good and suddenly when we sewing expensive and delicate tissue, she began to skip and turn the thread. Check if you are correcting it in a bobbing cap. It is desirable to navigate the instructions for refueling the instructions to your typewriter.
Strong tension of the bottom thread often adjust the tension of the lower thread is not necessary. To do this, it is better to loosen or increase the tension of the upper thread. But if you need to adjust the tension in the bobbing cap, do it carefully. Paul screws of the screw is the maximum value of its tightening or weakening.
Incorrectly filled the lower thread the lower thread should come not only under the plate, but necessarily. how on the right photo. Otherwise she can jump out and get confused.

The jan on the needle plate leads to the loop of the thread
The needle plate can affect the view of the line. If it is notched on it, then the thread can cling to them and under the cloth to form loops.
To troubleshoot the problem will have to be cleaned or change the plate. It flies if you help your hands, pull the cloth at sewing. For the proper operation of the machine should adjust the paw so that it does not clamp a lot of fabric.
Thread, clinging to the jar, begins to change his tension and be confused
Bottom thread (on a bobbin) thicker top
In the sewing machine, the top thread leading, it seems to pull down the lower thread. The elastic will be the lower thread, the easier it is to pull it up. Experienced seamstresses are more often taking the bottom on the room thinner than the top. It is necessary that it was easier to pull out.
Attention! Work on the typewriter better on those threads to which it is configured.
Understand why the lavety thread prevents sewing, in most cases you can independently. Roller repairs on YouTube are also easy to make it yourself, especially if he is simple. But sometimes it is better to call the masters. Appeal to it will be needed if:
Council of Expert. In the sewing machine “Tula” of the old sample and in other similar aggregates, the details are quite often. If the problem is in this, you can find a replacement by private announcements. Similar difficulties experience masters, which have a sewing machine “Seagull”. Avoid unnecessary spending will help careful care for technique, regular lubrication of its mechanisms.
