How to fill overlock

The sewing machine can be filled in many ways, of which none will provoke the appearance of defects during flashing of material in the form of passes, or the unexpected appearance of overcast stitches. In this regard, overlock is a more moody device. If the thread is not attached to at least one of several loopers, this is fraught with the appearance of gaps or sewing stitches in the seam line. Therefore, the process of guiding the thread in the overlock should be treated very responsibly.

General refueling scheme

To correctly thread the overlock, you must perform certain actions in the correct sequence:

  • install a spool of thread on the holder;
  • Pass one end of the thread through all the holes intended for it. So that the lines come out smooth and beautiful, the core of the spool holder is sent directly in the direction of movement of the thread;
  • it is important to correctly thread the thread through all the tension devices: one of them takes the thread to the side, the other tightens. Therefore, it is necessary to observe the sequence of the direction of the thread. In modern overlocks, these devices are combined into one that performs both actions;
  • put the thread in the looper so that it moves perpendicular to the movement of the material during sewing;
  • when the thread can be pulled out from under the presser foot, it means that the threading has come to an end.

Important! It is advisable to check whether the thread is correctly fixed in the overlock. To do this, practice on unnecessary material. If the thread breaks during sewing, or gives a strange loop, it means that somewhere it was incorrectly threaded.

Chinese three-thread overlock dressing

The most famous representatives are Overlock 51 classes, as well as Typical and fn2 7d. He earned his popularity due to facts such as:

  • the possibility of use not only in professional workshops, but also at home;
  • unlike his brothers, who cope only with delicate fabric, he is able to work on thick, stiff or rough fabric.

If you learn to refuel it, then in the subsequent work you can fix the threads already on any model of this type of device, since the sequence remains the same:

  1. Insert the thread into all the holes on the device’s body, which are designed to guide them.
  2. Including the thread should be in the tension device.
  3. Then she is led down, threaded through the eye of the needle and removed through the foot.
  4. Practice on a test piece of tissue.

The tension device is typically located in the right looper. This should be considered during refueling. If the thread needs to be fixed inside all overlock mounts, then the use of multi-colored species is allowed. Such a trick will help to correctly figure out which thread you need to release at the moment, and which one to tighten.

Reference! Access to the left looper is much harder than to the right. Therefore, experienced seamstresses use tweezers in the threading process. And if you could not get one end of the thread into the hole, it is advisable to remove the plate from the needle, and try again.

Four thread overlock dressing

The process of fixing the thread in 3-thread equipment is practically no different from the same sequence of actions on a 4-thread machine. There are only a couple of differences:

  1. The left needle thread tensioner has a thread with a left needle, and the right one has a thread with a right needle.
  2. On the right side, the first looper on the left side belongs to the first looper thread tensioner, and the first looper on the right side corresponds to the first looper thread tensioner on the left side.

But there are other ways to refuel in a four-thread overlock. As a rule, the manufacturer indicates them on the equipment case.

Attention! There are four-thread overlock models equipped with the F.A. system. S. T., which helps to thread the looper located at the bottom. Including it makes the procedure for threading threads through the upper loopers easier.

Class 51 overlock refueling scheme

Any Chinese overlock refueling instruction is based on a certain sequence of actions:

  1. It is necessary to begin fixing the thread from the looper located on the left side. The thread is pushed into the hole of the protective right cover, through the device that guides it, and then poked through the hole of the left cover.
  2. Then the thread is passed through all the holes located in the thread tension device. She is circled around him, then threaded into the channel, which directs the thread to the looper itself.
  3. Next, the pulley is rotated clockwise until the looper, which is on the right, is at the top above the needle plate.
  4. Then, adhering to the rear direction, the thread is circled around the lever, where the right looper is, and hooked to the hook.
  5. Then the pulley is again rotated so that the left looper is at the bottom. Next, the thread is passed through a hole located in the looper, and the pulley is continued to turn until the right looper is again above the needle plate to raise the left looper. When he takes the upper position, the thread is fixed under the scapula. If somewhere at this stage a mistake is made, it will break during operation.
  6. Now you can do the right looper. The thread is passed through a hole in the plate of the needle thread tensioner. Then it is directed through the hole of the knife plate located on top, which in turn is an element of the looper thread tension device on the right side.
  7. The pulley is twisted until the right looper takes up position. The thread is pushed into its hole under the hook, which gives an impetus to the final direction of the thread.
  8. At the final stage, the needle thread is passed through a tension device, then through a hole in the plate, bypassing the regulator rod around.
  9. The thread is fixed under the hook, then thread into the eye of the needle.

There are many videos that clearly demonstrate how to refill an overlock.

What tools for refueling and overlock adjustment are needed

Such moments can be determined in the process. As a rule, the necessary additional tools depend on which particular overlock part you need to configure at the moment:

  1. Thread Adjustment. To do this, you need to stock four coils of multi-colored species. If the equipment is three-strand, then three coils.
  2. Checking the quality of the lines. In this case, you will need a piece of fabric from any material on which you can test how the overlock sews, and then throw it away without regret.
  3. Threading the hole in the left looper. Due to its location, it’s not as easy to reach as some people think. Significantly facilitate this process, ordinary eyebrow tweezers.
  4. The overlock needle bent or broke. In the same category of problems is skipping stitches in the seam line. A common mistake of beginners who either improperly installed it, or pulled the material very strongly with their hands. Therefore, it is always advisable to have spare needles at hand.
  5. Strong heating of overlock equipment, or its failure. The reason is the lack or lack of lubrication. At least it should be used every 6 months. For this, a syringe that can be filled with oil is suitable. It will perfectly reach and grease all hard-to-reach areas.
  6. Overlock knives do not work. Often there is a mistake of the new owners of the overlock machine: they begin to cut and process with them all the possible materials that they have available at the moment. This is a wrong judgment. The initial purpose of overlock knives is the processing of protruding threads and trimming the edges of very delicate and bulk materials. Therefore, for a novice user of such a machine it is better to always have a spare set of knives at hand.

It is necessary to refill the overlock correctly, as this can extend the life of the device and save you from various kinds of breakdowns.
