Six Simple Solutions to Common Sewing Problems

A: Jumper, the reasons for jumper are as follows:
1. The needle is bent, replace the needle with a new one.
2. If the needle hole of the needle plate is large, replace the needle plate with a small hole.
3. Incorrect threading, re-thread.
4. The needle is not installed correctly, re-install the needle.

B: Broken needle
1. The needle is too thin, and the needle of the appropriate type must be replaced according to the fabric.
2. If the sewing material is too thick, it is recommended to reduce the machine speed.
3. When the needle touches the presser foot, readjust the angle of the presser foot.

C: Poor stitching
1. The upper thread is too loose or too tight, adjust it reasonably.
2. If the bottom thread is too loose or too tight, adjust it reasonably.
3. The needles and sutures do not match and should be matched reasonably.
4. There is a big difference between the needle type and the fabric, and the configuration is reasonable.

D: Fabric wrinkling and fabric stretching
1. The thread is too tight, re-adjust the tension of the upper and lower threads.
2. The pressure is too high, release the pressure of the presser foot.
3. The position of the feeding teeth is wrong. Adjust the height of the teeth reasonably. When sewing thin materials, it is about 0.8mm, and for thick materials, it is about 1.2mm.

E: disconnection
1. Incorrect threading, re-thread.
2. The installation position of the needle is incorrect. Reinstall the needle.
3. The needle is bent or worn, replace the needle.

F: not online
1. The needle is not installed correctly, re-install the needle.
2. The bottom thread is too tight, adjust the bottom thread tension reasonably
In addition, the correct threading method of the overlocking machine is supplemented: thread rack---thread clamp---threading hole---thread passing plate---thread pulling plate---looper thread holder- --Thread Clamp---Thread Holder---Thread Take-Up Rod Thread Holder---Thread Take-Up Rod---Straight Needle
