The sewing machine is used when the fabric is cut into small pieces, and it is necessary to sew the edge of the fabric with the sewing machine (also called sewing) to prevent the fabric thread from unraveling.

Operation method of the locking machine:

(1) The longitudinal slot crossing mechanism is used. As long as the suture is embedded along the forced straight groove, the line can be led to the clamping tool. The operation is very simple and there will be no error.

(2) The opening action of the clamping plate adopts the linkage mode with the press foot, which is convenient for threading action.

(3) The threading part of the downbend needle is equipped with a lead device, so that the complex threading action of the downbend needle in the overlock sewing machine is easy.

(4) The length of the needle distance can also be adjusted externally during the sewing process by using the external adjustment of the needle distance adjustment disc.
