Finding out, or at least seeing a photo of how a modern sewing machine works, is not only informative, but also useful. Be sure to read this series of articles on modern home sewing machine repair. A visual representation of the device of a sewing machine will help you make the right choice when buying it, and also make you take more care of it later.
It is quite difficult to disassemble a modern sewing machine on your own, but in most cases you will not have to do this. But still, there are cases when you have to disassemble the sewing machine yourself. For example, when you need to replace an electric drive, a line does not form, a needle breaks, etc., and there is no way to go to a workshop, because your city or village simply does not have one.
In this article, you will learn how to properly disassemble (remove) the plastic covers of a modern household sewing machine of the usual inexpensive model from Brother, Janome and any other company.
Almost all models of modern economy class household machines are assembled in China, and therefore, in order to disconnect the plastic parts of the case, you only need “Phillips” screwdrivers. One screwdriver should have a Phillips head for medium-sized screws and one slightly more powerful, maybe even a flat head.
Screws for machines of European assembly (sometimes Taiwanese) often have some peculiarity. They can be unscrewed only with a special screwdriver (asterisk) with a special slot. First, look at which screwdriver you can use to unscrew the case mount, you may have to buy it from the store specifically for this. This photo shows the types of modern screwdrivers and screws. By the way, we will disassemble the sewing machine in the foreground. It is called "Dragonfly" - China. Its body is assembled on ordinary Phillips screws.
Video (click to play).
First remove all non-tooling parts. Start at the removable table, then detach the foot. Remove the stitch plate. To do this, use a flat screwdriver to unscrew only one screw (sometimes two). Naturally, you need to pull out the bobbin and the plastic hook or bobbin case, remove the bobbin and so as not to injure yourself, it will not hurt to remove the needle. Now you need to unscrew the screw indicated by the arrow in the photo and carefully remove the front cover. There is a special latch at the top of the cover, you need to disconnect it before “pulling out” it by force.
All screws do not need to be stacked together. When you start assembling back, it will be difficult for you to determine which screw and where it was. Therefore, mark them in any way convenient for you. For example, you can put a piece of paper with a mark next to each screw (s).
Now we will begin to disassemble the sewing machine, or rather to disconnect its plastic case, which consists of two halves. But first remove the hook cover. To do this, unscrew the screws indicated by the arrows. Just like the front cover, this part, in addition to screws, is also attached to latches. To loosen them, you need to insert a screwdriver into the slot and try to gently slide the cover to the left. On the back of the handwheel, remove the stitch selection knob. Just pull it firmly to the right. Immediately notice how it stood to make it easier to install it back.
And two more types of attachments are located at the bottom of the machine body. In many models of sewing machines, the rubber feet in the lower part of the body are also the attachment of the plastic body to the metal bed of the sewing machine. In any case, this model of the machine has two rear legs as such an attachment.But since we will only be removing the front part of the case, unscrew only one leg (top right).
For all sewing machines of this class, it is imperative to release the fastener indicated in the photo with the letter (A). Moreover, both screws do not need to be unscrewed, it is enough to release only the front side cover. In this case, you need to unscrew the top screw.
The very last, but most inconspicuous screw (B) remains. It is located in the depths of the front of the machine. Even at high magnification, it is not visible in the photo. The screw that you can see so clearly does not need to be unscrewed. This is the upper thread tensioner attachment. By the way, it remains in place after removing the cover. Consider this point and do not try to film it. Actually, unscrewing the screw itself is not difficult, it will be much more difficult to put it back. Therefore, hold the screwdriver on the magnet for a while, this will help you later.
Now you can remove the front cover, although it should be noted that other models may have an additional mount, but the principle is about the same. Look carefully, maybe your machine will have an additional mount at the bottom of the case. It happens that the fastening of the covers is hidden by plugs. Use a knife blade to pry the plug on the back of the machine and make sure there is no additional attachment there.
By the way, it is with the help of a knife that you will have to remove the cover, since in addition to screws, there are latches on the ends of the covers. Place the knife blade between the ladles of the case and gently try to move them apart by displacing the latches. Only now it is difficult to determine at once where they are located, so please be patient if you really decided that you definitely need to disassemble the sewing machine.
This is approximately the "picture" you will see when you can disassemble your sewing machine. Probably, it should be noted that the most difficult thing is not to find all the screws holding the covers to the case and to each other. It is very difficult to carefully remove the covers, to separate their latches. If you do it hastily, you can damage the plastic, which will ruin not only the appearance of the machine, but also interfere with the work. Rough spots in the sleeve area of the machine will cling to fabrics and even form puffs.
It is important to firmly decide whether you need to disassemble the machine with your own hands or not. If there is no other option, then be patient and attentive. Well, for what it is necessary to disassemble it, we have already mentioned above, but we will understand it in more detail in other articles.
The device of a modern sewing machine How a modern household electric sewing machine works. Major malfunctions of components and mechanisms.
How to disassemble a typewriter and replace an electric drive Sometimes it becomes necessary to disassemble the sewing machine, or rather remove the plastic case of the machine in order to gain access to some units. Such a need arises very rarely and it arises only when it is necessary to replace the electric motor of the sewing machine or the drive belt.
Sewing machine electric drive Just like the pedal, the electric motor does not need to be repaired by yourself. Moreover, there is nothing to repair there. The engine is either running or not running. If it does not work, and you know for sure that there is no other reason for this, then it needs to be replaced.
Bobbin winder Such a "trifle" as winding thread on a bobbin often creates a lot of inconvenience. For some reason, it is not always possible to do this quickly and “without problems”. Let's see why it is sometimes difficult to wind the thread on a bobbin and what needs to be done to eliminate minor damage to the winder.

Hooray! You have a new Brother sewing machine!
Compared to mechanical or old electrical (almost rare), this is fantastic.
And now, you are almost ready to believe in miracles and relax, as your miracle suddenly begins to break the thread. And vomits, and vomits.
You do everything strictly according to the instructions, you start to read the application intensively, change the thread, rearrange the needle, turn all the available adjusting wheels and nuts, but nothing helps.
We turn to the all-knowing Internet, and there are all the same tips from the instructions for use (which you have already followed for the hundredth time). And in the end, a wise recommendation - turn to the master.
Of course, you may be lucky, and you will stumble in your search on the magical saving phrase of a specialist - clean and remove the jammed thread from the upper thread tensioner, or otherwise from the upper thread tensioner spring... But where is it, and what is it, is the second question.
After all, looking at the typewriter, we see only a slot in the case, into which we stretch the thread, and what happens to it inside the case, we can't even imagine.
And believe me, even if you remove the casing, you will not immediately understand where to look for this cherished mechanism.
Let's try to help with our advice to everyone who faced the same problem.
1 First you need to turn off the sewing machine from the network. All actions will be performed with the power supply turned off.
2 Unscrew the screw on the front cover of the casing (there is only one, it is not difficult to find it).
3 And now the main thing with the help of our photo, find the mechanism, or, in other words, two parts screwed together with a large screw, clamping our thread.
To make it easier to get to it, gently turn the rotation wheel back and forth.
4 And then it's a matter of technology. If you have found the mechanism itself, then it will no longer be difficult to notice the stuck thread there. It is better to remove it with tweezers. Sometimes there is not one, but a whole bunch of threads, you must try to remove all of them.
5 After completing our procedure, screw the front cover back on. The procedure is complete.
Perhaps you have some information on how to prevent biting and thread breakage in the top take-up mechanism.
Maybe the mechanism just needs to be lubricated or some kind of gasket should be placed, which will prevent its further clogging.
We would be very grateful for your hints in the comments below. We and all visitors to our site will be glad to receive your comments.
We hope after that your machine will stop being capricious and will delight you in the future!
What are you going to fix in the sewing machine? With regards to products from the time of Stalin, nothing ... It works to this day. Modern breakdowns will torment, a bunch of settings get confused, requiring correction to get the desired result. We have nothing against progress, but historians consider a society preoccupied with consumption as an intermediate stage. Like a tax on bridges erected by medieval feudal lords to impose tribute on pedestrians. It got to insanity: buildings were built out of the blue for profit. Low-quality things are akin to ancient savagery and will become a thing of the past. Do-it-yourself sewing machine repair is a pleasure! The weak half is strong in needlework, when a strong helper is at home.
In 1953, Clifford Simak's story, The Ring Around the Sun, was released. The meaning of the plot: in orbit there are countless myriads of Earths located in parallel universes. Events developed against the backdrop of the curious invention of the eternal light bulb. Then the ever-mobiles appeared.Clifford described the fall of the consumer society, the goods were bought once, used a whole life, remember Stalin ... A revolution happened, working people, fearing to lose their jobs, began to destroy modernized factories, the most interesting thing was built by people moving between dimensions. In a ring around the sun.
Until 1829, inventions in the field of sewing machines would be called unsuccessful, although Leonardo da Vinci created the first drawings that would be equal to future generations. During the era of manufactories, the French tailor Timonier created a wooden model, which they immediately began to copy and reproduce. One replaced several apprentices. There were massive demonstrations of artisans who saw a threat to existence (I wonder what the rulers will do, if scientists create a computer that makes decisions, can grimace, they will immediately destroy it?). The matter went far: 200 local tailors destroyed the workshop of new mechanical sewing machines, Timonye had to flee, fearing for the safety of his life. Not the first time: the inventor of the loom suffered a similar fate.
The surviving fruits of the technological revolution
During his life, Timonier created a billion modifications of the sewing machine. Some technical solutions are still used by household, industrial modifications. 300 stitches every minute were made by machines, today's electric models are capable of producing three times more. For 200 years! The frequency of computer processors doubles every two to three years (growth has slowed down since 2010). Timonier's sewing machine worked with silk and other delicate fabrics.
In parallel, 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 present. The fabric feeder appears. The sewing machine is equipped with a horizontal curved needle, makes 300 stitches per minute, replaces three tailors. The workers of the USA revolted and destroyed the shop. The inventor had to flee, fearing for his life. The last stitch was probably made by Singer. Gives the needle a vertical motion, introducing the modern look of the toothed strips pressed by the foot. In 1900, a workshop in Podolsk was built, where 5000 people worked for the October Revolution. Initially, Singer parts were imported from the United States, 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 hinder progress. Imagine if inventors stopped producing promising technologies. Humanity will continue to explore caves and trees instead of cities with multi-storey buildings.
I immediately remembered modern economical light bulbs. I had a chance to talk to an old sewing machine, it became clear, probably, since the time of invention, the technology retained the principle, settings. The quality of the parts was not right. Although they discovered smooth surfaces (nanotechnology), they created strong alloys. A main shaft with a crankshaft is introduced inside. Moving parts of the sewing machine work from it. What will be stated below affects the repair of hand sewing machines:
The needle is directly connected to the shaft. To ensure the forward movement up and down, a crankshaft is held inside. An eyelet is made in the needle where the thread is threaded. When moving down, the fabric is pierced, the loop is captured by the shuttle moving in a circle, in one direction, in the other. For 1 revolution of the main shaft it manages to run back and forth.
The shuttle is driven by a separate shaft connected to the main one by means of a knee. The phase of movement is regulated by a screw. You can rotate the auxiliary shaft relative to the main one. Synchronization of movement is achieved. Let's discuss repairing the sewing machine shuttle.
The third component, which ensures the movement of the fabric along the seam in the desired direction, are the toothed strips. Made of steel, they move like the legs of a person when walking. They go down, go forward, go up, go back. There is one cycle per stitch.
It is important to correctly set the vertical position of the toothed strips.When the needle plunges into the fabric, the top edges of the teeth will be level with the sewing machine table.
Unlike other devices, the toothed strips are driven by two shafts. One is responsible for horizontal movement, the other for vertical movement. The adjustment method is the same. A screwed screw on the axis of the corresponding shaft, which changes the position of the segment relative to the phase of the main shaft. Correct adjustment of the toothed strips is achieved.
It is important to ensure the correct position of the needle in relation to the hook. Remember three landmarks to look up to. Please note: for modern models, the old ones are arranged differently, and adjustment is required once every hundred years (twice since the invention)!
In the lower position, the eye of the needle is 4 - 6 mm below the nose of the vertical hook.
The nose of the hook is compared with the edge of the needle - the distance from the top edge of the nose-hole is 1 mm.
When the top edge of the tab is aligned with the bottom edge of the hook nose, the hook nose should extend 1 mm beyond the needle.
Approximate guidelines, you can use it, decorating the horizon, the need to repair sewing machines with your own hands.
Wise mom instructs daughter correctly
Repairing the electric sewing machine is not the only thing to do. The heel clamp is adjusted so that the fabric stops crawling. Made with a special screw. There is a spring inside, so the setting can be approximate, it will rarely be required. This applies to stitch lengths. For thin fabrics, more frequent are recommended, for thick fabrics, rare. In mechanical machines, the reverse is often turned on with a handle, it is inconvenient when you need to sew a patch, it is better to forget about the inscriptions altogether.
It is much more important to set the upper and lower thread tension correctly. If done incorrectly, a number of unpleasant effects will occur when using a sewing machine:
When the upper thread tension is loosened, there will be loops at the bottom of the seam. It is corrected by a special adjustment mechanism until the result is satisfactory. You can loosen the bobbin thread with the bobbin screw. It is important to know: too little tension is not allowed - the seam will not work at all - too strong - the thread may break. The last two cases are malfunctions, take note.
Pull the upper thread too tight - the fabric begins to pull together. Seen from jagged, billowing edges. You can release the upper thread, pull the lower one. Please note that you should not be too zealous. The pulled thread breaks, as mentioned above.
Ideally, the interweaving of the two threads takes place within the material. When the needle rises from the down position, the loop is caught by the hook. A turn is made, an interlacing is formed. The needle rises, tightens the stitch. If the thread is not inserted correctly, it breaks. YouTube demonstrates a video: a working sewing machine was taken for repair, the master did nothing, took 1,000 rubles, returned the product. Then the situation surfaced, disgruntled clients harassed the guru. The money was returned, accompanied by small verbal parting words.
With a blunt, thin needle skipping stitches occurs. The thread number corresponds to the needle number. There is one feature in modern sewing machines that needs to be considered. For each needle, a guide stop was placed under the surface of the table, which did not allow the point to go to the side. The thicker the fabric, the greater the distance to it. Unfortunately, we cannot give any signs of a malfunction, just keep in mind: a similar setting has been noticed. Repair of a foot sewing machine has a special feature: the drive is switched on remotely. Except for the button, there is little difference. Repairing a sewing machine pedal is more akin to carpentry, soldering art.
Sewing machines do not lose their popularity even in the twenty-first century. Those who were born in the Soviet era remember that from childhood girls were taught to sew various things, from gloves to jackets and coats.
During the Soviet era, most people did their own sewing machine repairs. Even today, those who attend sewing and sewing courses understand that it is better to repair a sewing machine on their own than to take it to a service center:
Firstly, companies that repair sewing machines demand quite a lot of money from their customers for the services they provide.
Secondly, the device of even modern machines can be figured out in a matter of hours, one should only carefully approach this issue, and in the future this will allow repairing sewing machines without involving third parties.
Let's take a look at the basic rules for operating sewing machines:
Sewing equipment should not be placed near batteries or heaters. But at the same time, it should be in a dry room, in which there are no signs of dampness;
Before starting work, it is necessary to select the necessary materials and tools, needles and threads that will be needed in the process of work;
Before you start sewing, you need to make sure that the needle and thread guide are in the up position;
Remember that the sewing machine must be helped at the time of sewing by pulling the fabric towards you;
After the sewing work is finished, raise the presser foot and pull out the fabric. Next, cut the thread, having found a free end in advance, the length of which will be equal to a maximum of seven, but at least five centimeters.
