Zigzag does not work in a sewing machine

The sewing machine does not sew. Why does a sewing machine not work

If the sewing machine does not sew a “zigzag”, then there can be many causes of the malfunction, starting with the weakening of the fixer mount and ending with damage to various mechanisms. Such problems can occur in any devices (from domestic technology “Podolsk 142”, “Seagull” or “Aurora” to imported multifunctional models “JUKI”, “Janome” or “Astralux”).

Specialists of the Unified Service of the AiSberg service carry out the repair of sewing machines of all famous brands (from basic models Jaguar, Singer and Brother to professional MerryLock, Bernina, Veritas, Husqvarna or Pfaff). Diagnostics of malfunctions and their elimination are carried out by the company’s engineers at the client’s house, which allows not to transport the device to the workshop. You can call a specialist at a convenient time for you by leaving an online application on the site or by calling our operators 8 (495) 213-11-90

The seams in the coal are processed by a stitch zigzag together. After grinding the details, it is necessary to pierce the allowances, and then iron the seam in the right direction and only after that mix. After waving during further processing, the seams will also need to be ironed. Before hugging in order for the edge to be clean, it is necessary to cut all the crumbling threads and irregularities, and after hugging, also remove all the threads sticking out of the lines. The step of the line needs to be configured according to the thickness of the fabric. No need to wrap it often, like a loop. in one place, but also not to make a stitch too big. This not only worsens the quality of the line, but also gives a neat look. The width of the zigzag put at least 3 mm., since the line should keep fabric threads. The stronger the fabric crumbles, the wider the zigzag should be and more often the line.

Looping the lower and upper thread, bad line

• The nose of the shuttle dull.
• The shuttle settings were lost or its orientation in space was violated.
• The needleman is not calibrated or installed too low/high.
• The lower thread is thicker than the upper. The more elastic and thinner the thread from below, the more reliable the unit works. Sometimes an incorrectly selected thread causes passes, cliffs and other defects.
• The needle does not fit this type of fabric. If both threads do not form a line, know that this is the case.
• A break in the lower thread occurred, which is why it simply wrapps an endlessly on the bobbin. The winding on the bottom of the material in this case stops and the upper thread does not capture the lower.
• Absent or incorrectly pusher works. Sometimes the nose does not capture and passes the thread due to the simulation of the movements of the needler and the lower compartment.
• Arushena Streaming of a bobbin cap (burr, screw skew, etc.). Usually such a defect is easily reinforced.

What disadvantages could have a zigzag.shaped seam

In photo 1, switching, from left to right injection, occurs under the needle plate.

On the handle, the width of the zigzag, there is a number 5. And from the edge of the hole, on the right, to the needle of more than 0.5 mm and on the left of more than 1 mm. Or vice versa. It doesn’t matter now.

The needle should switch over the needle plate.

This is when, a little more, she will switch. In the photo 1, the needle, in the right top. zero.

If the needle is not included in the needle plate, but rests on it, pull out the needle, from the needle holder.

Find this point, lower zero.

When a little more. a little, and the needle, under the needle plate, switch. Found? Stop! We don’t twist the flywheel anymore! But we need to lower it, on the left injection. See photo 1-1.

In the photo 1. 1, the hole in the needle plate is shown.

• Now we unscrew, the rear screw m 5 is completely. Photo 1-2.
• Weaken the screw m 6 for 4 turnover. Photo 1-3.
• Remove the block, above the worm, 1-2 mm. Photo 1-4.

In the photo 1-2, a screw of fastening of the axis of copies to the machine body

The photo 1-4 shows two details, zigzag block:

According to photo 2, a zigzag copper does not reach 1 mm to the middle of the ledge, a copy disk.

Here in this position, the needleman, we lower the zigzag block, to the worm.

We rotate the pulley. We follow the needle. And we follow the actions of the copy, regarding the copy disk.

Copyr, reached the second protrusion, and the needle, remaining at the left point, left the needle plate, zero to the top point.

In the photo 4, the copier sank down, with the protrusion into the hollow, the needle, remaining in the upper zero, now switched to the left injection.

In the photo 5, a copier, reached the middle of the hollow, and the needle fell to the lower point zero.

Photo 6, copier, reached the second corner of the hollow, and the needle came out of the needle plate, on the right injection, and stood at the top of the zero.

Photo 7, copier, went up to the first ledge, and the needle switched to the left injection.

The cycle is closed. Copyr in the middle of the protrusion. Needle in the lower point zero.

Adjusting to the input and exit of the needle, on the zigzag:

If, there is a focus or delay with photo 2-8, weaken two screws, for 1-2 revolutions. These are screws, without a head, on the worm of the main shaft, photo 9 and turn the worm, for 10 minutes, around the main shaft, clockwise. Check. Or 10 minutes counterclockwise. Check. The circumference of the main shaft, we take, for the clock of the watch.

Signs of normal work

Not all for ordinary household sewing use overlocks, especially if the sewing machine is not used regularly, but only periodically. A zigzag.shaped seam is used to process the fabric, with its help you can get a neat and beautiful mark of the edges of knitwear. Signs of high-quality Switch-Zigzag:

• All stitches are the same, there are no differences in length.
• The constant pitch is observed between the punctures located in the neighborhood.
• The line goes evenly on the material, does not pull it off. Such a problem is often found when working with thin canvases.

On dense material, zigzag processing is almost always good and spectacular. But such a line on cotton and similar tissue properties looks bad. These nuances relate only to the quality of sewing and professionalism of the tailor/tailors, do not address the correctness of the functioning of the equipment.

The correct formation of the loop

To understand why the PFAFF, Veritas, Jaguar or Juki device stopped creating stitches, it is worthwhile to figure out how they are formed. All cars be it manual, electric or mini form the seam equally.

The machine seam is formed when the needle and the shuttle device is interacted. When lowering the needle to the extreme position, the nose of the shuttle is suitable for the tip. He captures the thread, wraps it around him, forming a stitch.

The most important parameter in the creation of a line is the gap between the needle point and the shuttle nose. It should not exceed 0.2-0.3 mm. If the gap is larger, the shuttle cannot capture the thread, the seam will not form. A pass is formed in the line.

Why is the machine not sewing

In addition, we remember that all the details rotate, move relative to each other, and if the car cannot move, it does not sew, then there are five reasons for this, as in the song of Nikolaev, five. The first reason is a “dry” machine: the details require lubrication, or the lubricant has hardened from the wrong oil, from a long stagnation. You need to pump with kerosene, drive away the car at a fast speed (without threads) and drip clean special oil for cars or spindle. Old machines have free access to all parts to lubricate the machine, so you need to use it. The second reason is that the machine is clogged with honors and weaving dust, even worse if it is saturated with oil. Remove the needle platinum and clean the entire space and gear rack. Weaving dirt must also be cleaned under the top cover, where the mechanism of the paw and needle is located and lubricate these mechanisms. At the factory, the mechanic did not approach the car until the seams clean the machine. If after that the machine did not sew, then the master came into business. The third reason is that the belt is scrolled and does not pull the fly wheel behind it: shorten or tighten the belt. The fourth reason is the difficult course of the car (buzzing, but does not touch the place) from the fact that the belt is tightly pulled. If possible, then adjusting the slot in the engine mounting lever (watch a video about the “seagull”), or stretch the belt made of genuine leather with your hands in the bench drive, or replace the belt. The fifth reason. the machine does not turn on in the working move. they forgot to tighten the friction screw, in modern machines. the fly wheel is put forward to the winding position for winding. Well, and there is still the sixth reason. it’s you ! Inept sewing by car. watch video lessons! If the car sews, but bad, then this already applies to adjustments.

This article is primarily focused on people involved (or planning to engage in) sewing at an amateur level who decided on:

• acquisition of the first sewing machine due to its absence,
• replacement of an old sewing machine with manual drive,
• replacement of an old sewing machine with electric drive.

Currently, specialized stores have a huge variety of modern sewing machines, with a more thorough consideration of which the head begins to circle. So what is important: brand, prices, functionality and other nuances? Each sewing machine has functions, strengths and weaknesses that may have a different level of priority for you. Let’s try to consider the main features of the sewing machines, which (in my opinion), you need to pay attention before buying:

The price category of the sewing machine depends, of course, on the capabilities of the buyer. But if you do not plan to sew more than yourself and your family, there is no point in buying expensive production models.

Brand

About the brand can be told in more detail by people who directly worked as sewing machines of a particular brand, to impose anything in this article on my part will be quite incompetent, since my experience is limited only by 2 brands: Podolsk and name is hidden in order to avoid advertising =).

Number of lines, number of loops.

If you are seriously not engaged in embroidery, decorative design of clothes (and not only clothes) in the form of a border of flowers, beams, rhombuses, then it makes no sense to buy a sewing machine with a large number of lines. In fact (based not only on my experience) will be used 3-5, a maximum of 6-8 lines: straight, zigzag, elastic lines, imitation of overlock lines and something else if necessary. Imitation of overlock lines, of course, can not be compared with a real overlock, but nevertheless, very often helps out in the absence of the specified apparatus.

The weight of the sewing machine usually varies in the range from 5 to 12 kg. The easier it is, the easier it is to transport it if necessary. In fact, the machine should not be light, and the heavier it is, the more metal parts are in it, and the more reliable and more stable when sewing at high speed. A light machine is more likely to jump on the surface. In my opinion, the optimal weight starts at 8 kg. It is important to consider the weight in the ratio with the dimensions of the sewing machine.

Type of shuttle. Type of shuttle device in a sewing machine.

There are currently three types of shuttles: “swinging”, “horizontal” and “vertical double promotion”.

• The simplest of them is “swinging vertical shuttle” (classic). He makes oscillatory movements. In cars with this location of the shuttle, the bobbin is inserted into the metal case, then the shuttle with a bobbin is inserted into the machine.
• “Horizontal” shuttle is the most common type of shuttle in cars. It is quite convenient to use. The bobbin is inserted directly into the car body. In addition, a transparent window is provided on a needle plate, through which you can see how much thread is left on the bobbin. A shuttle of this type is also good because it reduces the vibration, and, accordingly, the noise is minimized. Horizontal shuttle does not require lubrication. Such a device also prevents the tangling and cutting of the lower thread.
• “Vertical shuttle of double shirting (rotational)” is used in the designs of machines belonging to the category of expensive and is considered more reliable. The rotational shuttle easily copes with high loads and has the highest sewing speed. The passage of the stitches is unlikely, the refueling of the thread is convenient and simple.

In fact, the layman has a choice only between the swinging and horizontal shuttles. Everyone chooses this feature of the sewing machine according to their preferences, but my choice is horizontal shuttle.

Sewing speed adjustment

The ability to regulate the maximum sewing speed is a very convenient function, especially for beginners. In her surprise, I found that you can still find sewing machines without the possibility of adjusting the sewing speed. I advise you to avoid them.

There are four main types of sewing machines: mechanical, electromechanical, electronic and computer. The cost increases in approximately the same order

• Mechanical machines work on the mechanical effort of the user (manual or footing).
• Electromechanical have an electric drive. an electric motor that drives a fly wheel in motion. The speed of work depends on the degree of pressing on the knife pedal. Functions are controlled by switches on the machine case.
• Electronic sewing machines have an electric drive and electronic control panel. The built.in microprocessor controls the needle on the fabric. Using the electronic panel of the sewing machine, you can select the necessary operation.
• Computer machines can be connected to a computer. It is possible to download new embroideries and types of lines, as well as program sewing operations.

Preparation for work

Properly configured sewing machine. half of success. The preliminary setting algorithm below will help you protect the device from failures as much as possible.

• Make sure that the device is installed on a flat and motionless surface;
• Insert the needle into the needle holder;
• Install the coil with the upper (leading) thread and connect it to the needle;
• Place the lower thread in the bobbin, and the bobbin in the shuttle;
• Connect the network cable and pedal.

Now the device is completely ready to work. If you have done everything right, the probability of a shuttle thread or a shuttle fall from the grooves will significantly decrease.
