Technical Field

[0001] The utility model relates to the technical field of sewing equipment, in particular to an anti-curling device for a sewing machine. Background Art

[0002] In modern society, people are increasingly pursuing an improvement in their quality of life. When it comes to clothing that showcases their image, they are also paying more and more attention to aesthetics and comfort. In the production process of underwear, the seaming and joining process of clothing has a great impact on the comfort of wearing underwear.

[0003] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material together;

[0004] When a sewing machine is used to sew clothing, the clothing needs to be moved so that the clothing contacts the needle of the sewing machine so that the opening of the clothing can be sewn. However, the clothing is very likely to curl during the movement. At this time, the sewing machine needs to stop working, and then the staff needs to repair the curled clothing before it can be processed again. This process greatly reduces the sewing efficiency of the clothing. Therefore, a sewing machine anti-curling device is needed to solve this problem. Utility Model Content
