Problems, malfunctions of sewing machines. Repair of Janome sewing machines Self-maintenance of Janome sewing machines

Once a week I always get a call and a completely upset girl’s voice informs me that the newly purchased machine is completely broken and does not want to sew.

1. The most common “problem” is that the car suddenly starts to weave heavily. Loops 2 centimeters long are formed from below, they are wound around the shuttle and everything gets terribly tangled. Simple logic tells the young lady that since the loops are on the bottom, then there is a problem with the bottom thread. After which, on the Internet there is advice about adjusting the lower thread and the inspired fairy unwinds the bobbin case, the parts scatter on the floor, and a sobbing, trembling voice is heard in my phone.

If you don’t get to the point of unscrewing the bobbin case, then the situation can be easily saved. All you need to do is correctly fill the top a thread.

The trouble is that many instructions do not clearly describe the procedure for threading the upper thread into the thread take-up. General principle Refills are most easily understood from the page from the instructions for Pfaff 1142:

The most important thing here is to raise the presser foot, turn the handwheel so that the thread take-up is in the upper position and thread the thread into the thread take-up.

If the machine still makes giant loops on the wrong side, check the threading again. More than once I have met ladies who swore with all the treasures of the world that everything was threaded correctly, that she had been sewing for a hundred years and could not make a mistake, and upon arrival our specialist discovered that the thread had not gotten into the thread take-up. After this, the ladies turned very red in the face, apologized profusely and gave him a hundred rubles for the trouble.

Correct threading allows you to cut off 99% of cases of strong looping on the wrong side. The remaining percentage may indeed be due to machine malfunction. Usually this effect is caused by burrs on the needle plate or in the shuttle and is best addressed to a qualified mechanic.

2. The second “problem” often arises among buyers of the Janome MyExcel w23u machine. Symptoms of a breakdown are as follows: the LED does not light up and the needle lift button does not work.

This “malfunction” can be treated very simply - you need to move the bobbin winder axis to the left position.

Another one is connected to the winder frequently asked question- Why doesn’t the bobbin snap off when winding is finished? Having become accustomed to this behavior of the winder on the Chaika, the buyer waits for a click and presses the pedal with all his might. However, in most modern machines, the bobbin does not unlatch. As winding proceeds, the rotation speed simply slows down and the winder stops.

3. Owners of machines like Janome 7518a (1221, etc.) often come to us with the question “Why does the machine sew slowly and growls loudly?”

These machines have a limit switch on the pedal. maximum speed. You can accidentally press it with your foot and not notice it. If the car growls at you, just check the position of this switch.

4. If the stitching turns out to be “loose”, there is no tension in the upper thread, pronounced loops are visible from the inside, and the lower thread is stretched by a string - rethread the machine with the presser foot raised. Perhaps the thread did not get into the tensioner plates. Another reason is that a piece of thread or other debris has gotten into the tensioner plates and is preventing them from coming together. Try, with the presser foot raised, to clean the space between the plates with a piece of thick thread.

If the bobbin thread tension is lost, check to see if debris has gotten under the tensioner spring on the bobbin case (bobbin holder). Do not attempt to clean under this plate with a needle or other metal objects. If you scratch the shuttle, you will be tortured to repair it. Better take a toothpick.

5. I have two favorite questions - why the stitching is herringbone and why you can see the “dots” from the top thread. There is only one answer to these questions - you need to use threads of the appropriate thickness.

I like the seams on my shirts. Smooth, straight, you’ll just admire them. Now you can see what threads are used to sew a good men’s shirt and compare their thickness with a “magpie” from the store. It turns out that the threads on the shirt are twice as thin. At the same time, shirt fabric is not the thinnest. The problem is that it is very difficult to find high-quality threads on sale with a thickness less than No. 50. On suiting fabrics and with a stitch length of 3 millimeters, the “magpie” gives an ideal stitch on almost any machine. And if you try to sew thin silk with a needle No. 90, threads No. 40 and stitches 1.5 mm long, the “Christmas tree” will appear in all its glory, regardless of the design of the shuttle.

“Herringbone” must be on any lockstitch machine, since the upper and lower threads are intertwined with a “rope”. It is enough to mentally remove the fabric from the seam and imagine how the threads are intertwined, it becomes obvious where the “herringbone” comes from. The herringbone becomes almost invisible if the interweaving of threads is formed deep between the layers of fabric, and for this the thread should be no thicker than the warp thread. Also, the visibility of the Christmas tree is affected by the length of the stitch. It is possible (on industrial machines) to reduce the visibility of the “herringbone” on the front side if you slightly rotate the needle around its axis, but then on the back the “herringbone” will become more noticeable.

6. Pulling of the fabric when sewing zig-zag and decorative stitches is also not a malfunction. The laws of physics cannot be abolished, and if you try to perform a wide zig-zag with a “magpie” pattern on a thin and loose fabric, then only an adhesive stabilizer will help to avoid contraction. You can, of course, try to loosen the tension of both threads and take thinner threads, but radical way- stabilizer.

7. A knocking sound when sewing at the time of puncture is in most cases caused by a dull or unsuitable needle. Correct selection needle gauge is especially important when sewing from thick fabrics. A universal needle with a rounded tip cannot move apart the tightly woven fibers of the material, and punches a hole with a knock. For such fabrics, you need to have sharp needles marked Jeans and Microtex in stock. After replacing the needle, the knocking, in most cases, disappears.

8. Another “problem” that customers regularly encounter is the lack of a foot for making buttonholes in the kit. It's easy to find - it lies separately from the main set of legs, in a removable table under a hinged lid. Janome overlockers often “lose” the converter for two-thread seams. It is unsuccessfully packaged in a bag, separate from other personal belongings, and hangs on a pin for installing coils.
In Husqvarna Emerald computer machines, sometimes an entire pedal is “lost”! The manufacturer has provided for it comfortable spot inside the case.

9. I also remembered the “problem” with turning off the teeth of the fabric conveyor. The teeth are perfectly turned off by the corresponding switch, they fall down, but they don’t want to come back, no matter how much you click the button. The casket opens simply - the conveyor teeth rise to the working position after a full revolution of the flywheel. All you have to do is move the switch back and start sewing.

If I remember anything interesting, I’ll add it here.

What are you going to fix on your sewing machine? Nothing regarding products from Stalin's time... It still works today. Modern ones are tormented by breakdowns, a lot of settings go wrong, requiring correction to get the desired result. We have nothing against progress, but historians consider a society preoccupied with consumption to be an intermediate stage. Like a tax on bridges built by medieval feudal lords to impose tribute on pedestrians. It got to the point of insanity: structures were built out of the blue to make a profit. Poor quality things, akin to ancient savagery, will become a thing of the past. Repairing sewing machines with your own hands is a pleasure! The weaker half is strong in needlework when there is a strong helper at home.

History of the sewing machine

In 1953, Clifford Simak's short story, A Ring Around the Sun, was published. The meaning of the plot: there are countless myriads of Earths in orbit, located in parallel Universes. Events developed against the backdrop of the curious invention of the eternal light bulb. Then the evermobiles appeared. Clifford described the fall of the consumer society, a product was bought once, used for a lifetime, remember Stalin... A revolution happened, working people, afraid of losing their jobs, began to destroy modernized factories, the most interesting thing was that they were built by people moving between dimensions. In a ring around the Sun.

Until 1829, inventions in the field of sewing machines will be called unsuccessful, although Leonardo da Vinci created the first drawings that future generations would follow. The French tailor Thimonnier created the era of manufactures wooden model, which they immediately began to copy and reproduce. One replaced several apprentices. There were mass demonstrations of artisans who saw a threat to existence (I wonder what the rulers will do if scientists create a computer that makes decisions and can grimace, and they will immediately destroy it?). Things went far: 200 local tailors destroyed the workshop of new mechanical sewing machines, Timonier had to flee, fearing for his life. This is not the first time: the inventor of the loom suffered a similar fate.

Surviving Fruits of the Technological Revolution

During his life, Thimonnier created a billion modifications of the sewing machine. Some technical solutions are still used in household and industrial modifications. 300 stitches were made every minute by today's machines electric models capable of delivering three times more. For 200 years! The frequency of computer processors doubles every two to three years (growth has decreased since 2010). The Thimonnier sewing machine worked with silk and other delicate fabrics.

At the same time, in 1834, Walter Hunt invented a model with a shuttle, reminiscent of modern ones. By 1848, Elios Howe created the first sewing machine containing the features of the current ones. The fabric feeder appears. The sewing machine is equipped with a horizontal curved needle, makes 300 stitches per minute, and replaces three tailors. US workers rebelled and destroyed the workshop. The inventor had to flee, fearing for his life. The last stitch was probably made by Singer. I gave the needle vertical movement by introducing modern look jagged strips pressed with a foot. In 1900, a workshop was built in Podolsk, where 5,000 people worked by the October Revolution. Initially, Singer spare parts were imported from the USA, then they began to be manufactured in Russia.

Brother, Janome, Bernina, and other brands of sewing machines appeared. People are afraid of change, but change is inevitable. Revolutionaries slow down progress. Imagine if inventors gave up on promising technologies. Humanity will continue to explore caves and trees instead of cities with multi-story buildings.

Setting up the sewing machine

I immediately remembered modern energy-saving light bulbs. I had a chance to talk with an old sewing machine, and it became clear that the technology had probably retained the principle and settings since its invention. The quality of the parts is not what it used to be. Although they opened smooth surfaces(nanotechnology), created strong alloys. The main shaft with a crank transmission is inserted inside. It powers the moving parts of the sewing machine. What will be indicated below affects the repair of manual sewing machines:

1. The needle is directly connected to the shaft. To ensure translational movement up and down, a cranked transmission is installed inside. The needle has an eyelet where the thread is threaded. When moving downward, the fabric is pierced, the loop is captured by a shuttle moving in a circle, in one direction, in the other. In 1 revolution of the main shaft it manages to run back and forth.
2. The shuttle is driven by a separate shaft connected to the main one by means of an elbow. The movement phase is adjusted with a screw. You can rotate the auxiliary shaft relative to the main one. Synchronous movement is achieved. Let's discuss repairing the sewing machine hook.
3. The third component that ensures the movement of the fabric along the seam in the desired direction is the serrated strips. Made of steel, they move like human legs when walking. They go down, go forward, go up, go back. There is one cycle for each stitch.

It is important to set the vertical position of the gear bars correctly. When the needle is inserted into the fabric, the top edges of the teeth will be level with the sewing machine table.

Unlike other devices, gear bars are driven by two shafts. One is responsible for horizontal movement, the other for vertical movement. The adjustment method is the same. A tightened screw on the axis of the corresponding shaft, changing the position of the segment relative to the phase of the main shaft. Achieved correct setting gear strips.

It is important to ensure correct position needle relative to the shuttle. Remember three guidelines to follow. Please note: concerns modern models, the old ones are designed differently, and adjustments are required once every hundred years (twice since the invention)!

1. In the lower position, the eye of the needle is 4–6 mm below the nose of the vertical shuttle.
2. The nose of the shuttle is compared with the edge of the needle - the distance between the upper edge of the hole and the nose is 1 mm.
3. When the upper edge of the eye coincides with the lower edge of the hook nose, the latter should extend beyond the needle by 1 mm.

Approximate guidelines, you can use, decorate the horizon, the need to repair sewing machines with your own hands.

What is regulated in sewing machines?

Repairing the electric drive of a sewing machine is not the only thing you can do. The heel pressure is adjusted so that the fabric stops sliding. This is done with a special screw. There is a spring inside, so the adjustment can be approximate and will rarely be needed. The above concerns the length of the stitches. For thin fabrics, more frequent strokes are recommended; for thick fabrics, sparse strokes are recommended. In mechanical machines, the reverse is often turned on by hand; it’s inconvenient when you need to sew on a patch; it’s better to forget about the inscriptions altogether.

It is much more important to correctly set the tension of the lower and upper threads. If done incorrectly, a number of unpleasant effects will occur when using a sewing machine:

1. If the top thread tension is loose, there will be loops at the bottom of the seam. Corrected special mechanism adjustments until the result is satisfactory. You can loosen the bobbin thread using the bobbin screw. It is important to know: the tension is not allowed to be too weak - the seam will not work at all - too strong - the thread may break. The last two cases are malfunctions, take note.
2. If you pull the top thread too tightly, the fabric will begin to tighten. Visible by the jagged, billowing edges. You can release the top thread and tighten the bottom thread. Please note: don't go too hard. The overtightened thread breaks, as mentioned above.

Ideally, the interlacing of two threads occurs inside the material. When the needle rises from the lower position, the loop is captured by the shuttle. A turn is made, an interweaving is formed. The needle rises and tightens the stitch. If the thread is inserted incorrectly, it breaks. YouTube shows video: working sewing machine They took it for repair, the repairman did nothing, took 1000 rubles, and returned the product. Then the situation came to light, dissatisfied clients disturbed the guru. The money was returned, accompanied by a little verbal parting words.

With a dull, thin needle, skipping stitches occurs. The thread number corresponds to the needle number. Modern sewing machines have one feature that needs to be taken into account. For each needle, a guide stop was placed under the table surface to prevent the tip from moving to the side. The thicker the fabric, the greater the distance to it. Unfortunately, we cannot provide any indications of a malfunction, just keep in mind: a similar setting has been noticed. Repairing a foot-operated sewing machine has a special feature: the drive is turned on remotely. Except for the button there is little difference. Repairing a sewing machine pedal is more akin to carpentry and soldering.

The semi-automatic loop is performed in four steps. You will have to turn the stitch selection dial four times:

1. Setting;
2. Left side of the loop;
3. Setting;
4. Right side of the loop.

The automatic loop is completed in just one step. The size of the buttonhole itself is automatically determined by the size of the button that is placed in the foot to make the automatic buttonhole.

You probably already know the basic rule when it comes to sewing needles: replace them with new ones after every big sewing project. Even a slightly dull tip or damaged needle eye can seriously affect the sewing result. Indeed, on modern sewing machines, the needle pierces your fabric at a speed of 600 to 1,000 stitches per minute. But at the same time, it is also important to choose the appropriate type of needle.

If you look at the needles on offer in the most ordinary sewing store, you may see at least a dozen different varieties. In appearance they are all similar, unless you look at them with a magnifying glass. But different types needles have different needle eyes, different points, different rods, etc. All these parameters have great importance for work.

Let's look at the main types of needles in accordance with the attached illustration:

1. Universal/standard
Features: slightly rounded tip, standard for sewing machines.
Materials: silk, rayon, cambric, chiffon, organza, linen, georgette, poplin, ribbed corduroy.

2. Jersey

Materials: thin knitted and knitted products, single (one-sided) jersey, corset fabric, knitwear.

3. Stretch
Features: Medium rounded tip.
Materials: highly elastic knitwear, simplex, latex, lycra.

4. Jeans/denim
Features: sharp tip.
Materials: denim, canvas, twill, faux leather.

5. Microtex
Features: thin shaft and very sharp tip.
Materials: microfiber, fine and tightly woven material, such as silk, taffeta, etc.

6. Leather
Features: The tip has the shape of a blade and cuts through the material.
Materials: suede, pigskin, calfskin, goatskin leather.

In addition, it is important to consider the manufacturer of the needle. We express our gratitude to the Japanese company Organ Needles, which helped us prepare great material on needles for sewing machines.

Flash card requirements:

The flash card with designs must be formatted. Optimal size flash cards - up to 4 GB. It should not contain any extraneous files: documents, photographs, films, music.

Create a folder for the design:

You insert the formatted flash card into the turned off machine. Then turn it on and wait for the download process. The machine creates a folder on the EmbF5 card (the name may vary slightly). Also in in some cases, depending on the class of the machine, a MyDesign folder may be created. After that, take out the card.

Transferring the design:

You transfer the design to the card either by simply copying or using a special software(Digitizer MBX). The design must match the size of the hoop you are embroidering on. If it extends beyond the hoop, the machine will not open it. In this case, the design should be divided into several individual ones using special software.

The first digit on the left is the last digit of the year of manufacture. For example, if your sewing machine was manufactured in 2007, then the first digit will be 7. And if in 2014, then the last digit will be 4.

The second number from the left is the quarter in which the model was produced. 1 - production month from January to March, 2 - from April to June, 3 - from July to September, 4 - from October to December.

Other figures refer to general information manufacturer.

For example, serial number 431092594. The model was produced in the third quarter of 2014.

To perform a double stitch, you will need a double needle (two needles on one holder). If your sewing machine produces a zigzag width of 9 mm, then the distance between the needles can reach up to 9 mm. For machines with a zigzag width of 5 or 7 mm, the distance between the needles should not exceed 5 or 7 mm, respectively.

A sewing machine has two spool pins that hold spools of thread. The rods can be vertical or one horizontal and the other vertical (the rod is included additionally in the package).

Install two spools, thread the threads symmetrically behind the thread guide, then into the double needle. Select the straight stitch sewing function and use the standard zigzag foot.

A double stitch is formed on the front side of the fabric, and a zigzag stitch is formed on the back side. To process knitted fabric, we recommend using double stretch needles 130/705N No. 75/4.
