Description of several broken threads of computerized sewing machine

In useComputerized sewing machineDuring the sewing process, the machine often has the problem of thread breakage. The reason why the sewing machine has this kind of problem is mainly because the suture is subjected to abnormal tension or is cut, worn or broken by a part of the sewing machine, which causes an abnormal thread breakage. Due to the different reasons for the thread breakage of the computerized sewing machine, the shape of the thread breakage is also different, mainly including the following situations:

One is the cut-off thread: the thread of this kind of computerized sewing machine is cut, and the suture section is mainly cut-shaped, and there is no mammoth, especially like a knife-edge cutting. For example, the sewing material is thick, the needle is thin, or the sewing thread is damaged along the way, or the sewing thread is cut due to the tight fit of the machine. Recognizing the shape of the sewing thread head and judging the degree of damage and matching of machine parts in time is extremely beneficial to the on-site maintenance of the computerized sewing machine.

The second is a horsetail-shaped broken thread: the suture has a horsetail-shaped section, which is mainly broken due to friction. It is often a precursor of cutting-type crushing. For example, if the parts of the computerized sewing machine are hairy, the needle and the thread are not properly matched, etc., it is easy to cause the suture to break due to friction damage.

The third is curved thread breakage: in the sewing process of the computerized sewing machine, a certain resistance suddenly occurs and the suture breaks. At this time, the suture is curled after the break, and the section has hairs but is not long. It can be seen that this kind of thread breakage is mainly caused by resistance to the suture, such as wrong wiring, wrong puller action matching, high pressure of the suture tension regulator, etc.

In addition to the above three kinds of thread breakage, the thread breakage of the computerized sewing machine also has a broken thread. The broken thread is flat in section with a little short hair, and the suture seems to be broken by machine parts. Therefore, it can be judged that this kind of thread breakage is mainly due to the reversal of the computerized sewing machine, loose parts or too tight parts.As a result, the suture cannot pass smoothly and break.
