How to install needles in sewing machines
The needle is one of the most important details in the sewing machine. From how correctly it is chosen and installed, the quality of the resulting line depends. At the same time, it is necessary to take into account the existence of various types of needles designed to solve specific tasks. Knowledge of how to insert a needle into a sewing machine, and the ability to do it will allow getting smooth and impeccable stitches.
At the beginning of the movement, the needle with the refilled thread moves down. When it comes to the fabric, then pierces her. In the extreme position at the bottom of the needle presses the thread, which passes through both gutters. long and short.
When a return movement occurs, the part that is in a large groove does not experience friction and remains relatively free. Where the thread passes through a short groove, it is under pressure between the cloth and needle. As a result, due to friction, it slows down. Because of this, the loop is based, which the shuttle picks up. Thus formed stitches.

For people, just beginning a familiarity with a sewing machine, refueling threads may seem so difficult that they will be ready to completely refuse to sewing. Instead of allowing a sewing machine to idle and collect dust, it will be wiser to just learn to refuel it correctly. Start work will have to wind up the bobbin, if it is not yet prepared, after which it will be necessary to fix in the car the upper (coil) and the lower (bobbing) thread.
- Check the top side of the sewing machine for the presence of a refueling scheme before starting to refuel the coil thread. Some models of sewing machines are displayed from above, a small scheme where the thread from the coil should go to further refill bobbs.  x source of information
Pull the thread from the coil. Pull the coil thread to bump it a bit and circle through the disk tensioner thread on top on the sewing machine. Typically, this tensioner is located from the opposite side of the sewing machine to the top side of the top side.  X The source of information to the disk tensioner can also be attached to a small wire that helps hold the thread in its place.
- Know that in the stores of fabrics and goods for needlework sometimes you can buy already tired bobbs, if you do not have a desire to mess around with winding bursts yourself.
Start winding the bobbin. For a few seconds, start winding the bobbin by pressing the sewing machine pedal or on a special button for winding (if it is from your sewing machine). So you will ensure reliable fixation of the thread on the bobbin. After a few revolutions, the bobbin can be stopped to trim the tip of the thread sticking out of her hole.  X source of information
Complete winding. Carefully push the foot on the sewing machine pedal or press the winding button again to fill the thread bobble. Winding can stop automatically when the bobbin will be complete, but if this does not happen, stop it yourself when the thread will be screwed onto the bobbin almost floss with its outer edge.
- The coil can behave more stable when sewing, if you install it in such a way that the thread leaves for it when you look at her in front.
- If on the sewing machine there is a refueling scheme of the upper thread, pay attention to the mark on the location of the coil pin and the direction of winding the thread from the coil.
- Be sure to spend the thread for the threader, and not in front of him, so that later she could calmly go down on the front of the sewing machine and then pave your U-shaped route there.
- Most likely, the car will be present on the car through this section.
Stretch down to hook her for disk tensioner. Following the instructions of the shooter on the sewing machine housing, pull the thread from the nietenher. Next, it will be necessary to hook it for the disk tensioner, located below the front on the sewing machine housing, and then raise the thread up again and spend it through or along the second niteenser (often represented by the slit). As a result, the thread is formed with an extended letter “U”.  X source of information
Spend a thread through the pitch. After designing the thread of a peculiar letter “U” you will need to hook a thread or spend through the hole located at the top of the numericality, and then omit it down towards the needle mechanism. The pitch is a metal part that sticks out of the sewing machine housing from the cable of the second niteen! Nutrition has a special hole or hook through which the thread should pass. When you execute this step, the thread will already draw a large S-shaped zigzag in front of the sewing machine.
Replacing the needle in the sewing machine
The quality of work on household equipment depends on the timeliness of the replacement of one of the tools to which the largest load is accounted for. Replaced replacement after several hours of continuous operation, sewing two or three products. Therefore, how to change the needle in the sewing machine correctly, has no less value than full equipment setting.
Preparation for replacing the tool is the same as when it is installed. After it should weaken the screw to get a spent needle. You can do it with a flat screwdriver. During this, the spent tool should be kept the other hand.
Current with the instruction where Lysk should be. Along the way, you can check how sharp needle: the sharp end should glitter.
Insert the needle follows. Fix it by tightening the clamping screw.
So why do you need a long groove?
Thread hiding in a long groove during a puncture of the material. If the thread has no place to hide, it will break!
Conclusion 1: The needle should always be addressed by a long groove in the one direction from which the thread refills:
In the photo of the needle of the “Podolsk 142” car, the “seagull” is all exactly also, the long groove is located on the part of the working. And filament on the part of the working, t.E from myself.
Conclusion 2: Thread and needle in thickness must match each other.
To pick up the needle and thread in size, take the needle in the hand with a long groove up, put in the groove thread, and swipe on the surface of the blade. If the thread protrudes over the groove, then the thread is too thick or the needle is too thin for this thread.
You should take the needle thoroughly, but not so much so that the thread is very free in the groove. It is also bad, but about it next time
Now, by understanding how the machine line is formed, you will never confuse aside to insert a needle into a typewriter, and also why the number of the thread must match the needle number
Check needle after installation
You should not start sewing immediately after installing the needle, it is worthwhile to check its stability and orientation. To do this, a trial line is performed on a thin flap. in slow and medium speed mode. At the same time you need to pay attention to the stitches. they must be even and have the same length. If the thread cut off, the needle of the needle must be changed so that it stands straight.
Today, hundreds of various types of needles are presented on the market. both imported and Russian. In order not to make a mistake with the choice, you need to remember the various marking series:
- Basic rods for household devices of a wide profile (in T.C. Overlocks and Coverlocks) are denoted by the label “HAX1” or “130 / 705H”;
- The needles of some displeasant machines and overlocks are labeled “HAX1 SP” or “ELX705”;
- Industrial models can be found in the “DPX5” tags, “0319-02” and “DCX27”.
Each needle has its own number expressing its size. The number is a 2-digit or 3-digit number, which denotes the diameter of the rod (in millimeters), multiplied by one hundred. The higher the value, the more thick and strong materials can flash the rod without the risk of deformation. Double needles have an additional dimensional parameter reflecting the distance between the rods.
In general, the main part of the selection sounds like this: the needle and thread in thickness must match each other.
Setting Rules for Modern Machines
Modern household cars are well thought out designers. The user requires a minimal understanding of sewing principles to adjust the following parameters and work safely with the device:
Set stitch parameters
Even the simplest models of electric household machines have a good selection of lines intended for sewing in various techniques. The selection of the mode also depends on the tissue used. Master can manually adjust the length and width of the stitch to get the best quality line.
Attention! For thin and delicate tissues, the pitch step must be shorter.
In the user manual, there is usually a description of the modes of operation, compliance with certain operations to the tasks, tissue types. For some materials and modes, it is necessary to change the width of sewing and even needle.
Types of lines in a modern electromechanical sewing machine
Installation of the needle relative to shuttle
So during the work of the seam, a smooth, without skipping, must adjust the formulation of the needle relative to shuttle. In principle, this adjustment has a zigzag when working.
Normally, the working needle, rising from the lower position by 1.8 mm, should meet at the point with a shine. You can adjust this position with the help of a key, weakening the screw, fixing at this moment the flywheel.
If you cannot adjust this parameter independently, you must contact the service.
Adjustment of the needle product and tensioner
Breaking, sagging and looping working thread. a fairly popular problem. In this case, the machine makes skips in the line or sews uneven. The problem lies in the tension regulator: the tensioner can shift or fall out at all. The needle product in this case goes into the upper point along with the needle.
To solve the problem, it is necessary to weaken the screw and install the needle blade so that the grooves make the right position.
Setting the degree of tension of the working thread
This parameter affects the quality of the line: how smooth it, without clamps or sagging. If the tension is too strong, it is necessary to select a smaller number on the wheelbarrow. It is necessary to act gradually, checking the effect of each knob offset on the line.
How to Insert a Sewing Machine Needle
The lower halfway should not go upstairs. If the adjustment of the tension of the upper thread does not help, you should do the bottom.
Setting the degree of tension of the bottom thread
Check the correctness of this adjustment can be removable shuttle. If the bobbin inserted into it does not move when the whole design is suspended for a thread running from the bobbin, you need to loosen the tension. If on the contrary, the bobbin is too unwinding, the tension must be increased.
To enhance the tension, the adjusting screw must be pulled up using the tool clockwise, for weakening. against. Here you also need to act slowly, in stages, checking the adjustment after each step.
Setting the position of the gear plate
This do answers the movement of the fabric while working. At the moment when the needle skeins the material, the top of the tooth should be on the same level with the working surface. If this parameter is adjusted incorrectly, the fabric stands in place, or, on the contrary, stretches and breaks, the line falls unevenly.
The position of the bar fix simply. To do this, it is necessary to raise the paw, and to shift the rail so that it takes the correct position (usually this moment is described in detail in the user manual). Flywheel at this moment should be moved by itself.
Height of the toothed plank
It happens that the top point of the tooth is little raised above the surface. It can be fixed. Machine you need to tilt back. Slit screw slightly adjust the height of the tooth. When properly configured in the middle of the plate, only the teeth should be shown. Before the details should be raised in relation to the rear by 0.5 mm. If necessary, you can put the gasket.
Adjusting the degree of pressure of the paw
This parameter depends on the quality of the line and comfort when working. In simpler models, pressure paws is regulated by a screw that is on the holder. In more advanced models, this screw is bred on the body. It is necessary to work with it in accordance with the user’s manual for a specific model of the machine.
Preparation for installation of a shuttle block
When preparing a sewing machine to install a shuttle, it is worth thinking over the assembly and setting. Initially, pre-adjustment and finish fixation occurs.
Build and adjust the shuttle block
The shuttle block at the model is considered easy to configure. It includes the main node, as well as the mechanism of swing. For assembly from tools you need a set of screwdrivers and pliers. Adjustment is carried out due to the rotation of the flywheel clockwise. During the procedure, it is important not to damage the electrical drive.
