Do-it-yourself sewing machine repair veritas

Complex repairs of sewing machines related to the adjustment of units and mechanisms can only be performed by an experienced master. But such repairs are rarely performed, only when a part breaks down at the sewing machine and needs to be replaced with subsequent adjustment.
Most often, the sewing machine begins to "play up" if the rules of its operation, specified in the instructions, are violated or if simple settings and adjustments are not followed.

The main reason leading to a sewing machine malfunction is sewing fabrics that are not intended for this sewing machine model. Sewing a double hem on jeans, replacing a zipper in a leather jacket or bag, etc. - this is the main reason for the appearance of gaps in the stitch, thread breakage, needle breakage. Sometimes this can even lead to a breakdown of the sewing machine, subsequent complex repairs associated with the replacement of parts.

This article provides basic recommendations on how to set up and perform a simple DIY repair of a sewing machine.

Oddly enough, but it is the needle that is the most important part of the machine. During its “life” it makes thousands of punctures in the fabric and is not always light and thin, so sooner or later the needle point becomes dull, and the needle itself bends. And if at least once the needle hits the metal part of the machine body, the tip will bend in the literal and figurative sense of the word.
However, do we pay attention to this? The needle seems to be intact, so everything is fine. But take a magnifying glass and look at its point, its blade will be bent to one side. How would such a point pierce the tissue? There is only one way - to break it.

Now let's see how such a needle will form a stitch.
The thread passing through the eye of the needle will catch on the curved point and “slow down”, creating excess upper thread in the stitch. Here is the first reason the loops appear in the stitching. Moreover, a curved point will cause periodic thread breakage, especially in difficult to sew areas, when the upper thread is extremely stretched.

It turns out that sometimes the whole repair of a sewing machine consists only in replacing the needle.
Treat the needle with great care. Even if it outwardly has no blade defects and is not bent, try to change them more often anyway.
You do not need to throw out the used needles, as there are situations when the needles break one after the other, for example, when sewing a leather bag. Then remember about the jar with old needles.

Another reason for adjusting the sewing machine, especially the old manual machines such as Singer or Podolsk, is the incorrect insertion of the needle into the needle bar. The needle blade (fig. B) should be on the side of the hook nose. Remove the stitch plate and see if this is the case if the machine suddenly begins to twist and break the thread.

It often happens that a seamstress installs a needle from an industrial sewing machine into a household sewing machine. It is impossible to confuse a household needle with an industrial needle. A household needle has a special cut on the flask (Fig. B). But, nevertheless, it is the industrial types of needles that are installed. This absolutely should not be done. Firstly, you break the gap between the hook nose and the needle blade, hence the gaps in the stitches, and secondly, you risk damaging the sewing machine hook. Some commercial needles are noticeably longer than household needles and may touch the surface of the hook, scratch it or even damage the hook.

Figure (A) shows a diagram of how to check the curvature of the needle.Externally, the needle cannot be determined whether it is a curve or not, and if you put it on the glass (2), you can easily check the gap (1). Please note that an uneven, bent needle will cause gaps in the stitching and will break sooner or later.

To make the sewing machine “more confident” to work with fabrics that are difficult to sew, such as knitwear, stretch, thin natural and artificial leather, denim, needles are produced for sewing just such fabrics and materials. They have a special point shape and make it easier for the thread to pass through the fabric, almost eliminating skipped stitches and looping of the upper thread.
See Home sewing machine needles.

The thread looping in the stitching, as well as the characteristic knock during their operation, is perhaps the main difference between sewing machines with a zigzag, such as Chaika, Podolskaya 142 of all models. In short, the looping in the stitching occurs due to the uneven tension of the thread along its path: a broken compensation spring, rusty sole of the foot, the shuttle is incorrectly set, etc. However, it is impossible to set many parameters yourself without experience. Therefore, if you have a poor quality stitch, pay attention first of all to the condition of the needle, to the tension of the lower thread in the bobbin case, and whether the upper thread tensioner is working properly. Very often, children like to disassemble and assemble it, and after such a repair, the machine stops working.

It is sometimes necessary to repair the sewing machine Chaika quite often, and this is not due to the breakdown of parts, the parts are just very strong, but with the misalignment of the interaction of some units of the sewing machine, mainly the shuttle move.
Almost all of these tips for repairing a sewing machine Chaika can be used for other models of household machines.

First of all, check the nose of the shuttle with a magnifying glass, it should not have any chipping or rusty spots. If there are jags, they must be removed with a small file and polished to a shine, otherwise the thread will constantly linger behind the file marks, and loops will appear below. Only this must be done carefully so as not to blunt the tip of the shuttle nose.

Sometimes the bobbin (the bobbin thread is wound around it) can cause repairs to the sewing machine. Yes, it is repair, since an inexperienced "master" often disassembles and assembles all the units, when it is enough to simply replace the old metal bobbin with a new plastic one. If the edges of the metal bobbin are jagged and the bobbin case itself is clogged with thread fleece, the bobbin thread will come out in jerks and the upper thread in the stitching will periodically loop from below.

Often the reason for contacting a sewing machine repairman is that the upper thread is poorly regulated. You are tightening it almost completely, but the tension is still too weak. Look, perhaps, between the tensioner plates, thread fluff has accumulated, which prevents the washers from fully squeezing. The fastening of the tensioner (Chaika) may have loosened.

But still, most often, sewing machines such as the Seagull have a malfunction in the parameters of the shuttle and the needle. This is a complex type of repairing a sewing machine, more precisely adjustments, but for general information it is advisable to know the main reason due to which all the "troubles" of sewing machines occur.

The most common cause of a sewing machine malfunction is the upper thread. Thread breakage, looping in a stitch, uneven stitching, skips, etc. This often depends on the upper thread tensioner.
It is the fastening of the tension regulator (Seagull) that most often causes its poor performance. The plastic body is pressed under the pressure of the screw and over time the tensioner starts to stagger, or even completely "falls out" of the body.

In this photo, arrows indicate the attachment of the needle bar and tensioner. When sewing rough fabrics, intersecting seams on leather goods, and especially when hemming jeans, the needle bar may move upward with the needle.
Loosen the screw slightly and adjust its position, making sure that the blade and needle groove are in the correct position in relation to the hook (not turning left or right).
For details on how to disassemble and assemble the sewing machine tensioner, see the article "The device of the sewing machine tensioner Chaika".

Adjusting the shuttle mechanism of sewing machines performing zigzag stitching by Chaika, Podolsk, Veritas and others implies setting the position of the looper point above the needle eye by 1.2 (3) mm at the moment the looper point approaches the needle. This parameter is checked when the sewing machine sews not only the straight stitch, but also the left and right needle drop (when sewing the zigzag stitch).
The point of the shuttle must at the same time pass almost closely to the blade of the needle - this is the second condition that allows you to form a stitch without gaps.

In this photo, the arrow indicates the fastening of the shuttle shaft. Loosen the screw with a 10-point wrench, and holding the handwheel by hand, you can turn the shaft (together with the shuttle stroke) by adjusting the position of the hook nose in relation to the needle.

However, these are not all of the parameters for adjusting the interaction of the hook nose and the needle. There is such a parameter as the timeliness of the approach of the shuttle nose to the needle, namely at the moment when the needle starts to rise. The needle drops to the lowest point, and when raised by 1.8-2.0 mm, it should meet the nose of the shuttle, the shuttle removes the loop from the needle and wraps around itself.

But that's not all. For sewing machines performing a zigzag stitch, there is such a thing as right and left needle prick. With the left and right prick of the needle, the nose of the shuttle should “confidently” remove the loop formed above the eye of the needle. It should run slightly above the eye of the needle, but less than the distance of the eye of the needle itself, about 1 mm.

However, such adjustments are often not required to be performed, it is enough just to check with a magnifying glass how the shuttle interacts with the needle and make sure that repairs, adjusting the sewing machine are not needed, and look for another reason. For example, change the threads, thread them correctly, change the needle, clean the shuttle from dust and fleece, etc.
To make it easier for you to repair the sewing machine, disassemble the shuttle move and study its device. Observe how the stitch is formed when the stitch plate is removed. At the same time, check all the shuttle settings described above. See also How the sewing hook works.

The settings above can be used as a guide if you decide to repair your sewing machine yourself. As a rule, the machine will work normally with such gaps, but if you need to sew knitted fabrics that are too thin (silk) or, on the contrary, thickened fabrics, you need a more accurate adjustment of these parameters, which can only be set by the master.

In many cases, sewing machine repairs will not be necessary as long as the sewing machine is kept clean and lubricated periodically. If a seamstress takes care of her machine, then, therefore, she will protect it from overloading during work, not give it into the “wrong” hands, which means that the sewing machine will break less often.

After prolonged operation, clean the bobbin compartment and other accessible places from dust, fleece, oil stains. The shuttle itself and the shuttle mechanism should be periodically cleaned with a stiff hair brush. It is advisable to lubricate the machine at least once every six months, and after lubricating it, run it “idle” a little, especially if the machine is not used for a long time. During operation, the oil heats up slightly and penetrates better into units and places of friction.

It is better to draw machine oil into a medical syringe and bury it in small drops in accessible places where there is friction of metal parts.

The big enemy of all mechanisms is dirt and rust, try to keep the car in a cool, dry place.If the machine will not be used for a long time, protect it from dust, otherwise the oil from the dust will harden, and the machine will turn tightly, or even jam. This case is considered in the article Podolsk Manual Sewing Machine.

Inexpensive Sewing Machine: Pros and Cons
In this article, we will figure out whether such a combination is possible - "an inexpensive and good machine" and how an inexpensive sewing machine that costs 3-4 thousand rubles differs from a machine that costs 30 thousand.

We sew knitwear without gaps and looping
Many who tried to sew knitwear on an ordinary sewing machine noticed that the machine often refuses to make a beautiful and even stitch. There are gaps in the knitted stitching, the lower thread loops and sometimes breaks. Why is this happening and how can you fix it?

What is the difference between a carpetlock and an overlocker and a coverlock
The coverlock is a modern and versatile machine that can overcast fabrics, sew cover stitches and even stitch parts like a regular sewing machine. But it is impossible to repair such a sewing machine with your own hands, you must definitely contact the service center.

Decorative stitching in difficult areas
Sometimes it is required to make a perfectly even decorative stitch on the product, but you cannot draw a line with chalk - traces will remain, and there is not enough experience to scribble "by eye". Simple tips on how to sew on “difficult” areas.

What to buy a sewing machine
For those who rarely sew simple products or occasionally perform minor repairs on clothes, you can buy an inexpensive economy-class sewing machine. It performs almost all operations, is easy to operate, and most importantly, for such a machine, it will be cheaper to build repairs if suddenly it is needed.

Tips for setting up an overlock
The overlock is much more complex than sewing machines. It is almost impossible to repair an overlock without special knowledge and skills. However, repair or adjustment is not always required, sometimes it is enough just to adjust the thread tension and it will again overcast the fabric with high quality.

One of the legacies of the past Soviet era is the Veritas sewing machine, made in the GDR (Germany). Like other sewing equipment of the GDR, the models of these machines are quite reliable and durable. If you have such a sewing machine, do not rush to throw it away. The Veritas sewing machines (not all models) have a double-fit rotating shuttle used for industrial machines, which is already a sign that the Veritas machine can perform quality stitching. The swinging sewing hook, of the same type as the Chaika sewing machine, is used only in inexpensive, economy class models of modern sewing machines. Some models of Veritas sewing machines sometimes have an oscillating sewing hook, but more often, a rotating vertical hook is installed.

Repair of Veritas sewing machines is sometimes complicated by the lack of instructions and spare parts, since spare parts for sewing machine models from 81 to 1991. they just don't release it anymore. Moreover, the GDR has long been gone. Therefore, there is simply no place to buy them, except at the “flea” market. However, the reviews of almost all owners of Veritas sewing machines are only positive. Therefore, if the machine needs repair, try it, maybe you can make a small repair of the Veritas sewing machine with your own hands.

The Veritas sewing machine is a complex zigzag machine, that is, it makes different types of stitches based on a zigzag stitch. The shuttle stroke is the same as that of an industrial machine of class 97 and rotates in a vertical plane, which increases the accuracy class of the needle and shuttle, but provided that the shuttle unit is well adjusted.
The transmission from the main shaft to the lower shaft of the sewing machine is carried out using a woven nylon belt. This reduces noise when operating at high rpm.
The shuttle is set on a circular axle and secured with screws. If they are loosened, the hook can be removed, which means it is convenient to adjust the gap between the needle and the hook nose.

Sometimes a torn thread gets into the shuttle, and then it stalls, the machine jams. In this case, the only correct solution is to remove the shuttle from the axis. To do this, tilt the machine on its side and on the right side, loosen the two screws securing the drive gear on which the belt is put on, then remove the fixing plate. It holds the bobbin holder for the bobbin. Now you can turn the shuttle and loosen its screws on the shaft. After removing the hook, loosen the three screws that secure the lock plate with the nose facing the thread hook (hook nose). Then moisten the joint with solvent and try to remove or rotate the hook bobbin holder. There are six slots on its belt that need to be cleaned. The slots must always be clean. Assemble the shuttle in reverse order.
Attention! In case of inept disassembly at the shuttle, its locking ring, which locks the bobbin holder, can be broken. Be careful!

Sewing machine "Veritas Rubina", in addition to excellent performance, also has a completely modern look, is equipped with an electric drive and can carry out many different types of stitches. It is quite functional, that is, it is enough to put in a special needle for denim and it will be possible to hem jeans. And if you put a needle for sewing knitted fabrics, you can sew knitted clothes with high quality.

Veritas is a decent household sewing machine, especially when compared to older Soviet sewing machines. And even the old Veritas models, with a pedestal and foot drive, can perfectly sew modern knitted fabrics. If you have a manual for a sewing machine, then it is written in detail what fabrics can be sewn on Veritas, what sewing needles to use. How to select threads and needles, depending on the thickness of the fabric, thread and more.

The Veritas sewing machine is equipped with a TUR-2 electric drive. This engine is of very good quality. For many years of using these drives in our practice, none of them "burned out", did not break, and even the brushes did not have to be changed even once. There are several engines that “sat down”, that is, during prolonged operation they lose power and speed, but they work!
The electric drive of the TUR-2 brand can work for many years without requiring repair or replacement of brushes, even with intensive use of the sewing machine. But, like all electric motors for household sewing machines, it must work intermittently. Approximately half an hour of continuous work and a 10-15 minute break. This is especially important not to forget when processing curtains with a large footage.
With prolonged work without interruption, a specific smell of burnt electrical wiring appears. This means that it has overheated and needs cooling. Of course, the engine will not break down right away, but over time, from frequent overheating, it will lose power, and the machine will work slower.

Another detail in the Veritas sewing machine that should be noted is the sewing pedal. The sewing pedal often breaks with the Veritas sewing machine. And not so much because of an unsuccessful design, but because of a careless attitude towards it. The pedal body is very fragile and the upper part is secured by a small protrusion of the lower part. Often this protrusion breaks when hit or strong pressure and the pedal “opens”.
This damage can be eliminated by yourself if you restore this limiter. But first you need to disassemble the pedal. In order to disassemble the pedal, it is necessary to pull out the metal rod connecting both parts of the pedal base. This bushing is fixed with a screw in the lower recessed hole, which is usually sealed up and therefore it is difficult to understand that there is a screw there.
And yet, after self-repair, do not leave the pedal plugged in, since the pedal from the inept adjustment of the rheostat can be constantly on, overheat and cause big trouble.

If the strap of the Veritas sewing machine is cracked or torn, you can definitely replace it yourself. To do this, loosen the fastening of the electric drive to the sewing machine. Next, slide the drive towards you, the belt tension will loosen, and remove it. Replace the belt and tighten.
The tension of the belt should be set so that it flexes slightly when pressed with a finger. If the belt is too tight (overtightened), the sewing machine will make more noise and a stiff movement will appear.

A toothed belt is installed on almost any household old model of Veritas sewing machines. Thanks to this, the machine works noticeably quieter than Chaika, but there is also a drawback. This belt has the ability to stretch and then the machine can be scrapped, since it is impossible to buy a new such belt.

If you decide to repair your Veritas sewing machine yourself (which is not recommended), you should learn how to adjust the position of the needle, since the forward displacement of the needle is the cause of its breakage, and the displacement towards the seamstress is the cause of omissions. And the wrong position of the needle in relation to the hook nose is the cause of almost all stitch defects of the sewing line.

First, set the clearance between the shuttle and the needle in the plane of rotation of the shuttle. This gap on the right stitch of the zigzag sewing machine Veritas should be in the range of 0.1-0.05 mm. It must be adjusted by displacing the shuttle along the axis of its attachment. The shuttle is fastened with two screws.

The distance between the shuttle and the needle when it is in the lowest position is determined by the center angle of the shuttle. The beginning of the upward movement of the needle should begin no later than the moment when the nose of the shuttle and the needle form an angle of 45 degrees, and the straight line from the needle to the nose of the shuttle is 7 mm. At a lower angle, there will be gaps on the right stitch of the zigzag, at a larger angle, the upper thread will loop and break.

You need to adjust the gap by turning the shuttle on the axis (shaft) with loosened screws of its fastening. If there are skipped stitches on knitted fabrics when the right zigzag thrust is in place, you can increase the center pivot angle to 50 °. But at the same time, be sure to check if the line below has worsened. If the bottom stitch pattern starts to get lost, and the upper thread is clearly visible from below, reduce the center angle to a size that improves the bottom stitching.

The moment the shuttle nose meets the needle at the left stab of the zigzag. The distance between the lower edge of the spout and the upper edge of the tab is zero (pos. A), and on the right stab of the zigzag is 2 mm. You need to adjust this parameter by displacing the needle bar vertically and turning the shuttle.

Sewing machine lubrication
Lubrication of the sewing machine Veritas, Veritas Rubin and other models of machines from this company requires a lot of attention.Carefully study the instructions, read where you need to lubricate the machine, or independently determine all the rubbing units of the sewing machine and regularly lubricate them with a small amount of oil. Excessive lubrication can only do harm.

Instruction of the sewing machine Tekstim 8032
This model of an industrial sewing machine, like the Veritas household sewing machine, was produced in the GDR. It is intended for sewing light and suit fabrics. For small sewing workshops and ateliers engaged in sewing outerwear, the machine is simply irreplaceable. The mechanism for moving the presser foot together with the rail allows the machine to perform many specific operations, for example, fitting the sleeve when stitching into the armhole, etc.

Sewing machine care
Repairs to the sewing machine will not take many years if the sewing machine is taken care of and taken care of. Periodically clean the shuttle compartment from lint and thread residues with a stiff glue brush and lubricate the machine.

VERITAS is a German company that has been producing overlocks and sewing equipment since the late 19th century. She always keeps "ahead of the rest" in the introduction of the latest developments and the use of new materials. In 1943, the production of sewing machines with a rotating shuttle began. A few years later, all products began to be equipped with removable feet for various operations. In 1978, a machine that does not require lubrication appeared in the lineup. The mechanisms were processed with a lubricating compound automatically (which was just a sensation for its time!).

Significant milestones:

1980 - a new embroidery function was introduced.

1982 equipped with a Sewing Advisor.

1984 - double illumination of the working area.

1989 - LCD information display.

In the production of German sewing machines Veritas, by tradition, all requirements for assembly quality and for operational tests are scrupulously observed.

The brand is known not only here in Russia, but also in Europe and America. Universal models, designed with all the fashionable "tricks", attract customers in many countries. Sewing machines are durable, do not break, and require minimal maintenance. At the beginning of 2015, the concern has over 40 subsidiaries.

I assure you - this "German" is useful for both a novice seamstress and a professional dressmaker!

1) For almost all models (except, if my memory serves me, 8014-35) there is a special needle for coarse fabrics - if you need to hem a coat of the Soviet era (I’m sure you know their “Herringbone” style), sew the rolled-up jeans trousers, or sew car covers from rags - all this can be done without fear for the serviceability of the car. The main thing - do not forget to put a special needle that comes with each machine.

2) Electric drive - inside any model there is a "motor" TUR-2 - over several decades of operation of "Veritas", according to official data, a little more than a dozen motors broke without "outside help" - an impressive figure even against the background of durable Singer and Bernin.

ATTENTION: In order for the machine to serve you faithfully for many years, use it correctly: after every 30 minutes of operation, make a fifteen-minute pause, let the nodal parts cool down. Don't overheat.

3) All nodal connections are metal. Paradoxically, even such "folk" overlocks as "Podolsk" or "Chaika" have plastic in their construction. Veritas, on the other hand, is an example of truly German quality (at least in internal mechanisms, you will learn about the shortcomings of external ones later)

1) Weak pedal - the reason is most often in careless handling (although it is metal, but not "iron"), and not in the fragility of the part: the "wrapper" of the pedal is very fragile, and a sharp press can remove it and expose it.

2) It is not easy to find instructions and components (production was curtailed in 1991) - due to circumstances (the collapse of the GDR, the curtailment of the production of sewing machines, Perestroika), it is almost impossible to find spare parts in good condition, but if you can find the necessary part, then you have to redeem along with the machine in which it is built; a similar situation with the instructions - a paperback book either fades or goes to the trash after two or three years of use.

Below you will find an electronic version of the current operating manual for the machine.

3) The thread gets into the shuttle, the apparatus jams: this technical flaw is solved by disassembling and assembling the shuttle.

Shuttle disassembly instruction:

Summary: Compared to modern Asian and European overlocks, the hero of the article clearly loses - there is no that wide functionality, computerization (embroidery of complex models using an electronic installation connected according to the "computer-installation-machine" scheme) and international technical support.
But!
The cost of modern overlocks starts from tens and ends in hundreds of thousands of rubles - compared to them, our morally outdated "German" costs just a penny (the red price is 50-100 dollars).

You can buy a Veritas sewing machine:

1) From hands
2) In online stores focused on the sale of equipment "with history"
3) At collectors

Cars of this class have a rather complex design, perform a complex zigzag. The shuttle is vertical. The length of the stitch is adjustable, its maximum length is 4 mm.
According to feedback from
“The typewriter of the era before the general obsession with safety. Its thread take-up and upper thread tension adjuster are not covered with a casing, as in all modern ones.

In the days of the USSR, and now they were and are considered seamstresses.

You can crawl up to any mechanism, clean, lubricate - it is very convenient and, in my opinion, this is a plus for this machine. Unlike the Jaguar, where you can't crawl anywhere and for nothing. "

Reliable device. All parts are made of steel. Sews all fabrics, including leather. The machine uses a Polish-made electric drive. She can handle all types of seams - stitching in a lock - zippers, darning, sewing on buttons, edging, double stitching, zigzag, straight seam. The machine performs 25 types of operations. Feet, bobbins and spare needles are included.

Easy to maintain, there is free access to any part in comparison, for example, with a Jaguar. Any part of a complex machine can be easily cleaned and lubricated.
