How to thread the three thread overlock sewing machine? Four thread overlock sewing machine edging

The threading method of the overlock sewing machine is to thread the looper thread first, and then thread the needle thread of the machine.

The stringing method is as follows:

Before stringing, note:

1) It is necessary to adjust the relationship between the wire frame and the placement of the wire group, which is the same as that of a flat car; In addition, it is necessary to determine the order of the machine needlework and the upper and lower bent needle and thread balls to prevent the failure of the sutures from being twisted together. According to the wire frame, the wire frame of the sewing machine has a three-wire reel frame corresponding to the three-wire wire crossing board and is installed in parallel, and the two-wire wire reel frame corresponds to the two-wire wire crossing board. The two-wire reel frame and the two-wire wire crossing plate are generally installed on the right side of the machine platform for placing the upper and lower loopers; The three-wire wire frame is perpendicular to it and is used for placing the left and right machine needles and chain loopers.

When passing through the wire frame, the pay-off position is required to be appropriate and stable, and each wire hook of the wire frame should be aligned with the line column of their respective wire reels. Because the pressure of the thread clamp of the overlock sewing machine is generally small, if the resistance of the suture through the thread is slightly larger, it will affect the normal combination of the stitches.

2) The suture angle of each thread clamp is best adjusted within the range of less than 90. Because the angle is too large, the stitches often run out of the pinch board during sewing, so that the stitches are not well combined. The angle of the top line can be loosened and the peach-shaped wire plate can be rotated to adjust.

3) The upper looper hook must be hung up, if it is missed, it will also affect the combination of stitches.

The upper bend needle thread threading method is to pull the suture out of the second thread crossing hole of the second thread crossing frame, penetrate it into the second transverse hole on the right side of the wire rod on the upper cover of the casing (pass through it from back to front), and then thread the suture into the second longitudinal hole from top to bottom, so wrap it around, and then pull it out; Penetrate into the upper second hole of the four-eye wire plate, then bypass the wire clamp plate of the wire clamp (the angle of the suture through the wire clamp plate should be less than 90 °), pull out from the second hole under the four-eye wire plate, pass through the corresponding wire hole of the casing, and then penetrate into the left small plate of the wire volume adjustment plate, pass through the second hole of the upper looper shaft, pass through the wire frame fixed on the casing, and then thread the upper looper from front to back, and pull out the 50mm thread.

The threading method of the downward bend needle thread is to pull the suture out of the first thread crossing hole of the second-line thread crosser, penetrate it into the first transverse hole on the right side of the wire rod on the upper cover of the casing (pass it from back to front), and then thread the suture into the first longitudinal hole from top to bottom, so that it is wound and then pulled out; Penetrate into the upper first hole of the four-eye wire crosser, then bypass the clamping plate of the wire clamp (note that the angle of the suture through the wire clamp plate should be less than 90 °), pull out from the first hole under the four-eye wire crossing plate, pass through the corresponding wire hole of the casing, and then penetrate into the right small plate of the wire volume adjustment plate, pass through the first hole of the upper looper shaft wire, then pass through the upper looper pendulum rod wire, penetrate into the two holes of the lower looper shaft wire, and then wear the lower looper thread; The lower bend needle has three holes from the bottom to the top, threads the suture from front to back into the first hole, then from back to front into the second hole, and finally threads the third hole in front of the line groove, and then pulls out the 50mm long thread.

In fact, you can find someone who knows how to sew and ask!

I will, but I don't know how to tell you!

And you have a look at the manual!

I don't know if this will work for you!

Four-thread overlock sewing machine (edging machine) How to thread? How to string

Hello dear. The threading method of the four-thread overlock sewing machine (edging machine) is as follows:1

The 4-thread threading sequence of the overlock sewing machine is to thread the looper thread first, and then thread the machine needle. Before threading, we first need to put the thread ball and wire frame in place, otherwise it will be easy to wrap together for a while. 2。

To perform threading, we first place the ball of thread in a tray, then through the mast and finally through the round hole of the machine. 3。When wearing the machine, I instruct the teases to always pay attention to the position of the pay-off should be appropriate and stable; When you pass the only sell line hook, you should aim at your respective line bars.

4。When putting on the needle and thread, you must pay attention to the old curved needle hook must be hung on the line, otherwise it will affect the stitches; Moreover, it is necessary to adjust the suture clamp foot of each thread clamp to less than 90 degrees, so that the stitches can be combined better.

Tools Raw materials: sewing machine thread, overlock sewing machine (three-thread machine).

1. Put the spool into the tray, penetrate the mast and perforate, and the four wires are the same, as shown in the figure below.

2. Then, the threading method and the threading sequence.

3. A total of 8 places on the first line can be threaded, and 8 is behind the iron sheet.

4. The second-line threading method is basically the same as the threading direction of the first line.

5. The three-line and four-line threading method is basically the same direction of threading, and it is completed.

Hello dear. The details of how to thread the four-needle six-thread sewing machine are as follows: 1. The four-needle six-thread sewing machine is actually used for knitting or underwear.

2. You can take a detailed look at the information about it (there is an instruction manual when you buy a four-needle six-wire machine). 3. Note that when not in use, cover the nose with a cloth or cloth cover to avoid dust. 4. The main parts such as swing edges, prism sleeves, etc., should be used to pay attention to rust prevention.

5. When practicing with an empty car, the presser foot should be raised to avoid wearing the tooth surface of the cloth feeding tooth and the bottom plate of the presser foot. 6. The prism bed is most likely to accumulate sundries such as threads and cloth crumbs, which affects the normal rotation of the machine After each short period of use, the prism bed should be taken out and wiped clean, and then installed It is necessary to pay attention to the correct and flat installation when installing, so as to prevent the needle from being broken when using the machine. 7. Strictly prevent cloth, thread ball or other things from getting involved in the belt and hindering the normal rotation of the machine.

The machine without four needles and six threads is either an interlock sewing machine, commonly known as three needles and five threads, or it is called a multi-needle machine, commonly known as four needles and eight threads, or eight needles and 16 threads. Of course, the multi-needle machine can also use three needles, but it is six threads. Both of these machines are for knitting or underwear!

Hello dear. The above is my infiltration of this problem, if you think I am very satisfied, please follow me for a one-on-one consultation in the future, and then please do it a little manually, give me a thumbs up! Welcome to consult again!

1. First of all, put the spool into the tray, penetrate the mast and perforate, and the four wires are the same.

2. The threading method and the threading sequence are as shown below.

3. There are a total of 8 places on the first line to finish the thread, and 8 is behind the iron sheet, as shown in the figure below.

4. The second line threading method is basically the same as the threading direction of the first line, as shown in the following figure.

5. The three-line and four-line threading method is basically the same direction threading, and it is completed, as shown in the following figure.

How to thread the hand-held sewing machine? (It would be nice to have a picture).

Threading: Place the spool on the lower pole on the right side of the sewing machine, lead out the thread end, and pass it through in turn: the thread clamp (the one with spring screws on the left side facing you) - the thread take-up rod (the one that can move up and down towards your state Zhiru) - and then thread a few holes from the left side to the outside of the book from top to bottom to the nose of the needle.

Bottom line: Wrap the line around the bottom shuttle, the tightness should be moderate, reach out to the left side of the machine head, there is a position to install the shuttle, after hearing the "pop", use the manual, as long as it can't fall down. Gently turn the wheel to lead the line out, and it's OK.

<><4 Finally, it is aligned. Adjust the maximum length of the line to 4 and complete all the settings as shown in the image below. In this way, the problem is solved, as shown in the figure below.

Use a flat presser foot to pad the presser foot up, high in the front and low in the back.

The seam machine is to replace the needle board with a thin edge or grind it a little finer.

Use a flat presser foot to warp the presser foot pad. It's okay to go high in front and low in the back! The thread is tightened a little, too! The sewing machine is to grind the needle board a little finer. If you haven't been in contact with it, it is estimated that you will not be able to adjust it well! There are also needle boards for sale. Professional close-edged pinboards.

Presser feet, needle board need to be replaced with thin edges, you can also grind it yourself! The knife holder should be adjusted to the width of the car you want to car!

If the "yellow-green line" is not connected, wrap it with adhesive tape. The yellow-green line is a neutral line, that is, we usually have to confirm whether your machine is a three-phase three-wire or a three-phase four-wire, if it is a three-phase three-wire n line, do not need to connect, use.
