Abstract:
Disclosed in the present invention are a piping strip-zipper assembly, a suitcase, and a suitcase production process. One side of a zipper and a piping strip are formed into an integrated piping strip-zipper assembly by means of a co-extrusion process. Then, the piping strip-zipper assembly is directly and accurately mounted on the edge of a suitcase shell by means of the piping strip, thereby implementing the connection between the piping strip-zipper assembly and the suitcase shell; the step is simple, the production efficiency is high, and the production cost can be reduced. Compared with existing production processes during which a piping strip and a zipper need to be respectively assembled on a suitcase shell and then sewn on the suitcase shell, the mounting time is greatly reduced, and the problem that the production efficiency of existing production processes is low is solved. Moreover, automatic production of luggage can be implemented.
