The sewing machine misses the stitches: what to do

If the sewing machine sews with passes, this is reflected not only on the quality of the seams, but can also lead to a complete failure. That is, the line will not work at all. The reasons for the failure of the working capacity of sewing equipment can be different, many of them can be eliminated independently.

Sewing stitches are formed according to the algorithm:

The Zigzag Stitch EXPLAINED

  • First, the shuttle of the upper thread at the time of the “meeting” with the needle occurs.
  • The shuttle forms a loop, throwing the thread through itself.
  • As a result, the upper and lower threads are overlapped, forming a stitch.

The gaps and violation of the line are obtained if the nose of the shuttle cannot capture the thread. The most common malfunction, due to which rows passes occur, is a failure of the collapse of the joint work of the shuttle nose and needle. The needle.Properly configured relatively shuttle retains a gap of 0.3 mm with it. If this distance increases, the tip cannot capture the thread.

Before starting the repair of sewing machines and configure the gap, you need to make sure of other parameters:

  • The degree of tension of the thread;
  • Is the number of the thread, the brand of the needle is suitable;
  • Whether the thickness of the fabric corresponds to the characteristics of the equipment;
  • Relevance of the operating mode;
  • Whether accessories and material are selected correctly.

Check: in the gap, the reason or not can be two ways.

First. With a magnifier.

Second. Disassemble the machine (if it is not under warranty). You can try to configure sewing equipment yourself, but there is a risk of damaging other nodes and units. Therefore, the safest way of repairing is a professional call.

What is knitwear and why it is difficult to sew on an ordinary sewing machine out of it?

This term in sewing is meant a canvas, a ready.Made knitted or whole, a liable product, the structure of which is a loop interconnected. The stable expression “knitted fabric” is not entirely correct, t. To. Knitwear is not weed (like a fabric), but created using a knitting installation. Determining knitwear by appearance is not difficult. You just need to stretch the canvas. If the loop structure is noticeable, it means that it belongs to this class of fabrics.

Culinary

Today, there are many types of knitted matters: culinary, foot, interlock, Riban, Jersey, Piquet, Velur, Biflex, oil, Strech-tricky, etc. On ordinary sewing machines, it is not easy to sew knitted products. Details from this matter are stretched in all directions, keep their shape poorly, twisted at the edges. With inaccurate work with this matter, tightening can form on it. Ignoring certain nuances often leads to a passage of stitches.

Reasons for increasing the gap between the needle and the shuttle

Among the main reasons why the distance between the shuttle and the needle increases, the following can be called:

  • Incorrect parameters of the needle. The sewing machine is a complex device, therefore the needle in it is significantly different from the usual manual. Over, the MerryLock machine is unlikely to be suitable for Astralux or Jaguar. The fact is that the form of sharpening the blade, its length, as well as the shape of the flask of different models are different. If you decide to experiment and used the needle from one machine for another, be prepared for unpleasant consequences.
  • A blunt blade. How often to change the needles depends on how often and how much you sew. If you use the same needle for a long time, the blade is dull, begins to tear the fabric, the seams become sloppy. In addition, due to abrasion of metal, the gap increases.
  • The failure of the details, due to vibrations created by a swinging vertical shuttle. Their deformation and displacement gradually lead to an increase in the gap.

In addition to increasing the gap, there are other reasons why the line is not formed properly.

The main reason for the appearance of passes in the line

If the sewing machine Janome or the other makes gaps in the line, then on the fabric instead of a large number of stitches, a straight section of the thread is visible. The main reason due to which this happens is that the hook of the shuttle when moving down cannot hook the thread coming from the ears of the needle. The passage of stitches in a machine line happens if the seamstress does not pay attention to the defect in time. Such breakdown may have various reasons. In order to restore the correct operation of the sewing machine, you need to figure out why the sewing machine passes the stitches when sewing.

Repair of sewing machines

Of course, many of the above.Mentioned malfunctions can be eliminated on your own, especially if you have been sewing for a long time and know the principle of operation of your machine. But there are problems that are categorically not recommended to eliminate with your own hands. In order to repair the failed device, it is better to contact a proven service center.

Specialists “Repair” will quickly eliminate problems of any nature:

  • Check the settings of the device and, if necessary, will restore them.
  • Diagnose the device, find the failed part and fulfill its replacement.
  • Will clean and lubricate the sewing machine.

For our services are quite acceptable, and the result surpasses all expectations: quickly, efficiently and, importantly, at a convenient time for you.

High angle of deviation

The loop necessary for the stitch is formed from the side of the shuttle. A higher angle increases the chance of passing the stitch, as well as a too small loop. What to do in a similar situation? Try to give the needler the right angle, act carefully so as not to damage the device. In addition, the part can be modernized by washing a new bald on it. Select the angle suitable for your device and conduct the necessary procedure.

The phenomenon is common in mechanisms using the filament. Their elasticity is several times higher than the same indicators in branded threads. Since most manufacturers are focused on the use of not polished materials, the device may fail.

To eliminate, it is necessary to achieve an optimal angle of deviation of the thread. In extreme cases, you can slightly increase the stroke of the shuttle, creating an elevation on its body. To do this, use tin applied using a soldering iron. Attack it opposite to the needle, leaving a 0.8 millimeter gap between the exaltation and the needle. Can also help replace the thread with a better.

The upper thread cliff

The next most frequently asked question is “why the upper thread is torn in the sewing machine?””. The reasons are divided into two groups: related to the selection of accessories and threads and related to settings and adjustments. First of all, we analyze the reasons for the first group: check the quality and shelf life of the threads, check whether the number of the thread of the installed needle corresponds to the number of the thread, we change the needle for a new one if there are roughnesses and burrs on it.

If the measures described above are not given the result, then you will have to dig deeper. First you should check if the thread is correctly filled out. Even having sufficient experience in handling a sewing machine, one cannot be completely confident in the correctness of your actions-perhaps you are distracted and did something wrong.

If the machine is tearing a high.Quality and properly seasoned upper thread, then the problem may consist in a bobbin cap, namely in the spring of its lock. If it is weakened, it is recommended to purchase a new bobbin cap and replace the failed.

It is also worth checking the spray gun. The seizure of the spinker finger no longer ensures the retention of the flair of the bobbin cap during operation. If the defect is detected, a complete replacement of the sprayer will be required.

Track when the nose of the shuttle approaches the needle. If it is delayed, then the thread captive can break the thread. In this case, it is necessary to adjust the approach of the shuttle nose to the needle, which for beginners is quite difficult.

It is recommended to check the oil level in the crankcase and its intake in the ring border of the shuttle. In some cases, the problem with the cutting of the thread is solved by the simple addition of oil.

The upper thread can also be torn due to the malfunction of the adjustments in the mechanism of the foot. What to do in this case? If the paw plays, then it is necessary to fix it; If the lowered needle touches the foot, then it is required to adjust its position.

If your typewriter has been for several years, and before that it served properly, then probably the cutting of the thread occurs due to the resulting burrs and Zazubrin in the way of its passage.

Similar defects may appear in the following places:

  • On the surface of the sprayer;
  • On the cone of the spanger belt;
  • On the installation finger;
  • On the installation plate;
  • On the nose of the shuttle;
  • On fiber rulers;
  • In the ear of the threader;
  • On a needle plate;
  • On the surface of the washer of the tension regulator.

These vulnerable places must be cleaned and polished to a smooth surface. If possible, a part where there are a lot of burrs, it is better to replace with new.

Not only the upper, but also the lower thread can break. If such a malfunction appears, then the bobbins are most likely worn out. It is enough to replace them with new, completely identical to the old. Since the replacement of rhpyk is required after several years of the machine, when several generations of the purchased model have already changed on the market, to avoid problems with the search for spare accessories, I advise you to immediately purchase an additional set of rumps.

In addition to all these causes of the thread of the thread, excessive tension should also be noted. This error is often found in inexperienced craftswomen, so do not rush to call the master or call the service center.

Why does the machine pass the stitches

Sometimes the fabric itself becomes the fault. To exclude the possibility of this, it is enough to simply put a strip of newspaper under it and check the quality of the line.

If the problem has disappeared, you can safely continue to work “on paper”, the benefit of the density and aesthetics of the seam this lining does not affect. And it is easy to remove the newspaper. But if the council did not help, you will have to do more detailed study of the working part of the sewing machine.

Possible reasons

Sometimes the passage of stitches occurs due to the fact that the hole of the needle plate is broken. The fabric is pushed into it, the thread slows down and as a result of this on the needle does not form a loop. Before climbing in search of a “deeper” problem, it is worth excluding this.

If it is not a plate, then it is removed, armed with a magnifying glass and studying the process of interaction of the needle with a shuttle. Too much gap between these elements is the most common reason for passing the stitches. To exclude or confirm the “diagnosis”, it is necessary to put the machine into a straight line mode and crank it to the position when the nose of the shuttle is with a needle in one plane. Next, it is worth examining the “working area”, paying attention to the following.

  • The density of the fit of the spout of the shuttle to the needle blade is an optimal gap of less than 0.3 mm.
  • At what distance above the upper edge of the needle ears is the nose of the shuttle. It should be approximately 1.5 mm (the recommended value for thin tissues.1 mm, for thick.2 mm).

In the case when the gaps are observed, you should skip the machine at a small speed, looking at the side of which side of the needle is formed. Occasionally, the poor quality of the thread or its excessive tension prevent the normal operation of the sewing machine. In such a situation, the loop will be formed from the opposite side of the shuttle.

If, when evaluating the gaps, a deviation from the norm is detected, you will have to exclude possible reasons step by step.

How to fix

In the vast majority of cases, the culprit of large gaps is a needle.

If, at the time of capture of the thread, she defends from his nose by more than a third of a millimeter, it makes sense to remove it and examine it for curvature. It is easy to do this: you should attach the needle to the plane of the ruler and evaluate the degree of curvature. It should not be. If there is, the needle changes to a new.

The second most frequency “breakdown” is the wrong flask. It is round (for industrial sewing machines) or with different depths (for domestic). In addition, this element also varies in diameter. The easiest way to avoid problems associated with the size of the flask is to take the old needle with you before sending to the store for new ones.

If the nose of the shuttle at the time of capture of the thread is above the ear at a distance of more than 2 mm, then the problem is most often also in the needle-it is either too long, or did not “fall into place” because of the unsuitable flask.

In the same case, when the gap has changed when using the correct, no defects, needles, it is best to contact the service center. Attempts to independently adjust the height of the shuttle in an inexperienced user can lead to more serious problems.

Threads for knitted fabrics and their tension

“Doesn’t love” not a single straight.Line car. Knitwear for the sewing machine of the stitches is a test that not all cars withstand. True, modern household machines fully cope with this task, subject to some requirements. As you already understood, one of them is a high.Quality thread and its correct tension.

Overlocks with a differential rail can sew not only knitwear. This function is easy to turn off using a special handle. And even, on the contrary, you can “force” the rail to collect the fabric. You need to know that the overlocks of old models, including Overlok 51 classes. Cannot qualitatively perform the processing of knitted fabrics. And do not be surprised if the connecting seams of knitwear, processed only by a three.Minute overlock, will eventually burst.
