There is an erroneous opinion that threading a sewing machine is very simple. In practice, this process requires certain training, experience and knowledge of certain subtleties. It is often impossible to do this correctly even for professional seamstresses, not to mention ordinary users.

Inserting a thread into a modern sewing machine is quite easy. Here, this process can be done purely intuitively, besides, a detailed scheme of the fueling process is presented on the body of the device. This allows you to accurately execute the procedure as soon as possible. When operating the old model, problems occur with an enviable regularity.

Threading the thread in an old type machine

To properly thread in an old hand-held machine, you must strictly follow the sequence below. First, the thread is passed through the body mount located on the body, after which it is necessary to fill it in the regulating device, which is responsible for the tension of the upper thread. In doing so, it must be wound through a hook-shaped compensation spring. At the next stage, the thread is inserted into the eye of the yarn guide, then it is refilled in all the fasteners encountered along the way to the needle. It is very important to fill the thread from the side of a long trough located parallel to the needle. It is easy to grope, having spent a fingernail on a needle.

One of the main features of rotary-type machines is the absence of a yarn feeder, whose role is played by a fork. Here the thread does not pass in the eye, it is thrown on such a fork. However, machines with such a device are extremely rare.

Screw on bobbin cap

Correct thread the machine - half the battle. It is very important to ensure the required tension in the bobbin case. A small cog is responsible for adjusting this parameter. When it is tightened, the tension increases, when unscrewed, it decreases. The user should remember that the adjusting screw can not be strongly twisted, otherwise it just pops out and can get lost. The amount of tension depends on the following parameters:

  • thickness of the upper thread;
  • tension of the upper thread;
  • thickness of the fabric;
  • properties of the fabric.

Threading the thread in the overlock

The most common problems that many tailors face include difficulties in tightening the thread in the needle and eyelets of the overlock. The situation when everything is visually done correctly, and the overlock does not provide high quality of sewing, is very common. Even experienced seamstresses meet her regularly.

In comparison with the sewing machine, the overlock sets higher requirements for tightening the thread. Only if the thread is tightened properly, the overlock will leave a quality stitch. If there are misses, the thread will begin to tear, loop. Omission of stitches may also occur.

.

To avoid this, you need to carefully examine the path of the thread to the needle, loopers. At once it is necessary to check the position of the thread for its passage between the trays of the tensioner. It can jump out of this device, which will not allow creating a normal line. Also, problems will occur regularly if the thread does not get into the fasteners.

In addition, the appearance of stitches with omissions, loops is a consequence of the accumulation of down, strips of thread and other materials in the tensioner. After a long operation, clusters of streaks form between the plates, which leads to the expansion of the plates. You can eliminate this problem by dismantling the tensioner and manually expanding the plates, after which you will not be able to remove the streaks.
