Description

Technical Field

[0001] The utility model relates to the technical field of cloth running, in particular to a cloth running device of a sewing machine. Background Art

[0002] Generally, sewing machines are composed of four parts: machine head, machine base, transmission and accessories. The machine head is the main part of the sewing machine, which consists of four mechanisms: piercing the material, hooking the thread, picking up the thread and feeding the material, and auxiliary mechanisms such as winding, pressing and dropping the teeth. The movements of each mechanism are coordinated reasonably and work in a cycle to sew the material together.

[0003] However, in actual use, it is found that it is necessary to push the cloth manually. Due to the high flexibility of the cloth, the tensioning effect is poor during the cloth feeding process, which will cause the cloth to wrinkle easily, thus affecting the subsequent sewing effect of the cloth. Therefore, we proposed a cloth traveling device for a sewing machine to solve the above-mentioned problems. Utility Model Content
