In the production of sewing machines, we need to pay attention to every detail. Through the efforts of many people and the cooperation of many processes, we have completed high-quality sewing machine products. Many companies have formed special production lines to ensure the quality of sewing machines. However, improper use may lead to problems such as jumpers. The reason for the problem of sewing machine jumper is that we did not follow the operating instructions of the sewing machine. We not only know how to use the sewing machine, but also how to maintain it regularly. The following is the Sewing Machine Wire Break Sensor small series to explain the sewing machine jumper problem solution.

　　1、 There are jumpers on the sewing machine. It may be that the bobbin thread is too short to cover the bobbin thread.

　　Solution: at present, we only need to take out the shuttle and pull out the bottom line about 10 cm.

　　2、 The needle of the sewing machine has been used for a long time and we don't pay attention to maintenance, so the position of some parts has changed. At this time, there will be problems in sewing.

　　Solution: replace qualified sewing machine parts as needed, adjust the height of the needle bar, and the distance and clearance between the needle and the tip of the rotary shuttle.

　　3、 Because of the heat of the needle, the thread of the sewing machine gets hot.

　　Solution: for chemical fiber, needle should be used to ensure its cool.

　　4、 When sewing special materials, the ring of the sewing machine cannot be formed normally.

　　Solution: we should slow down the sewing speed and increase the smoothness of the thread.

　　5、 The presser foot slot is too wide. After the needle punched cloth is taken out, the movement of the sewing material of the sewing machine will affect the coil. This can easily happen when thin materials are used.

　　Solution: you can move the presser foot to the left or right according to the sewing material, or fill the solder in the wide groove, and then open the narrow groove to polish or replace the qualified presser foot.

　　The above five points are all about the solution of sewing machine jumper problem. Thank you for your understanding and support!
