摘要: A piping zipper assembly, a box body and a box body production technology. One side of a zipper and a piping are formed into an integral piping zipper assembly by a coextrusion technology. Then, the piping zipper assembly is directly and accurately installed on the edge of a box shell through the piping, so as to realize the connection of the piping zipper assembly and the box shell. The step is simple, the production efficiency is high, and the production cost can be reduced. Compared with the existing production process in which the piping and the zipper are assembled on the box shell respectively and sewn to the box shell, the present invention greatly saves the installation time and solves the problem of low production efficiency in the existing production process. Meanwhile, the automation of luggage production can be realized.
