Description

A kind of device of multi-thread suture zipper

The utility model relates to and a kind of slide fastener is sewn onto device on the cloth.

The connection element system of the spiral chain slide fastener of plastic cement is made of like chain continuous helical, by suture chain is sutured on the adjacent edge of cloth again, thereby formation slide fastener, and in the process of sewing up two cloths, article two, spiral chain is sewed up with two cloths mutually with intermeshing state, so every spiral chain is left space that suture needle penetrates for seldom in sewing process, is with two-wire spiral chain and cloth to be sewed up so generally all have.But, slide fastener is among use, usually because the friction repeatedly of slip pull head and excessive lateral pull make above-mentioned suture that fracture and disengaging take place, and cause the whole piece slide fastener not use, and then make the article of loading onto slide fastener scrap because of the inefficacy of slide fastener, moreover owing to respectively contain the reinforcement of a heart yearn as slide fastener in the spiral chain, thereby increased trouble and the cost of making, bring many inconvenience for production and user.

The purpose of this utility model is to provide a kind of device that can make spiral chain and cloth with multi-thread stitching.

The utility model is realized by the following technical solutions: utilize the chain that chain guide groove on the pin holder will be to be sewed up to separate, make the empty stomach of chain increase, the interior outboard flanges of the partition of pin holder and last needle plate flattens cloth stretching, and the chain and the cloth that will separate out with side by side suture needle more than three sewed up again.

The utility model makes that the slide fastener that is sewn is sturdy and durable, moreover because of having save the heart yearn in the chain, has reduced production cost because of adopting three-way above chain and the cloth sewed up, also makes process be simplified.

Below in conjunction with accompanying drawing the utility model is further specified:
