Zipper and manufacturing method thereof

Abstract

The invention discloses a zipper and a manufacturing method of the zipper. The zipper comprises a zipper belt, zipper teeth fixedly arranged on the inner edge of the zipper belt and a zipper head used for ensuring that the zipper teeth are meshed and separated, and further comprises beveling seams which are evenly formed in the outer edge of the zipper belt at a predetermined depth and a predetermined distance at intervals; a predetermined included angle is provided between each beveling seam and the corresponding axial line of the zipper belt; a lining cloth strip wraps the outer edge of the zipper belt in a seaming mode, is flush with the two ends of the zipper belt, and is longer than the zipper belt. According to the zipper, because the beveling seams are formed and the lining cloth strip are arranged in a wrapping and seaming mode, the length, the capacity and the hardness of the outer side of the zipper belt are increased, the beveling seams and the lining cloth strip play roles in correcting and supporting, capacity does not need to remain, and the manufactured zipper can avoid the problems that fabrics wrinkle, ensures that the fabrics are level, and do not arch, and can be straightly arranged on clothes.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a slide fastener and a manufacturing method thereof. Background technique [0002] Please refer to figure 1 , the existing zipper is mainly composed of zipper teeth 100, a zipper puller 200 and a zipper tape 300 (usually a cloth strip) carrying the zipper teeth 100 . The material of the zipper teeth 100 is generally metal or plastic, which neatly and evenly "bites" the cloth strips, which inevitably squeezes the cloth strips and makes the cloth strips stretch on the side of the zipper teeth; at the same time, one side of the zipper teeth 100 is The fabric with zipper teeth 100 cannot be retracted, causing the zipper to appear bowed when it is not closed, and it will be wavy after it is closed. Even famous brand zippers such as YKK zippers cannot avoid it. [0003] Thereby, the existing zipper is uneven and wrinkled, and it will affect the appearance and quality of the clothing ...

AI Technical Summary

Problems solved by technology

The material of the zipper teeth 100 is generally metal or plastic, which neatly and evenly "bites" the cloth strips, which inevitably squeezes the cloth strips and makes the cloth strips stretch on the side of the zipper teeth; at the same time, one side of the zipper teeth 100 is The fabric with 100 zipper teeth cannot be retracted, causing the zipper to appear bowed when it is not closed, and it will be wavy after it is closed. Even famous brand zippers such as YKK zippers cannot avoid it.

[0003] Therefore, the existing zipper is uneven and wrinkled, and it will affect the appearance and quality of the clothing if it is installed on the clothing.
