How to make refueling overlock

Overlock is a type of sewing machine that is designed for overcasting fabrics in order to give them a more beautiful appearance and prevent the blooming of the edges of the material. Such a device has not two threads, like a regular sewing machine, but three or four. The overlock threading scheme is described in detail in Operating Instructions to the device or schematically depicted on the device. If your model does not have such instructions for any reason, this article will explain in detail how to fill the overlock.

How to fill a four-overlock

How to thread in the overlock so that the seam on the overlay was smooth and beautiful? The first step is to prepare the rack for the coils or special reels for the upcoming work, tightly fixing them on the device.Then you should make sure that the strings that you are going to use for seaming match the type of needle used and are suitable for work on the overlock.

The process of filling a four-thread overlock is as follows:

  • move the sliding table and turn on the machine;
  • lift the knife, pressing it against the device and turning it clockwise;
  • put the spools of thread on the special pins and pass each thread through special thread tensioner.

 Four Thread Overlock

Pay your attention to the fact that each thread has its own three thread tensioners. On the inside of the case, a schematic instruction is indicated, which clearly shows the correspondence of each thread tensioner for a specific spool of threads.

  1. Hook the first thread on the three thread holders that are inside the device. Then insert the end of the yarn into a special socket, which is located next to the work table.
  2. 2 thread is passed through the corresponding tensioners and, unlike the first thread, is passed through through looper. In order to see the looper, you need to rotate the flywheel.
  3. The third thread is tucked in another way: after it passes through the tensioner, it must be held through the top holderwhich is located above the working table of the sewing machine and fill in the left needle.
  4. The fourth thread goes the same way, but, unlike the third, is tucked into the left needle, not the right one.

Then, lift the overlock foot, lowering the lever on the back of the case, and run all four threads under it. Lower the knife to its original position. Four thread overlock is ready to go!

How to fill 51 class overlock

Despite the large number of modern sewing machines, many use the Chinese "green" three-thread overlockers. They were popular in the 90s and today remain prevalent due to their relatively high quality. These Chinese cars are copies of domestic overlock classes of 51 classes, produced in Podolsk, respectively, and their threading pattern is the same.

How to fill such an overlock class 51, so that the quality of overlay was impeccable? This process is as follows.

  1. Pass the thread into the thread guide holes on the machine body.
  2. Next, through the plate tensioner.
  3. Bring the stretched thread down under the needle and pull it through the foot.
  4. Leave about 5 cm of fabric for a trial stitch.

The process of refueling the overlock of 51 classes is practically no different from refueling of modern four-strand models.

Gn1 overlock tips

In order for your Chinese overlock to work properly, you need to remember a number of important rules that will help to get a smooth and beautiful fabric overlay.

  1. Overlok gn1 is notable for its high purity requirements. Make sure that the working mechanisms of the machine are well lubricated and do not have traces of dust or dirt.
  2. When working with a machine, use thread of the same thickness.
  3. Incorrect thread tension level can lead to malfunction of the sewing machine. Adjust the tension before starting work with the machine.
  4. Use special needlesdesigned for class 51 machines. They are much shorter and have a thickened ear.
