Perforated cloth tape, perforated cloth tape manufacturing method and cloth tape hole manufacturing device

Abstract

The invention discloses a perforated cloth tape, a perforated cloth tape manufacturing method and a cloth tape hole manufacturing device. The device comprises a drying drum and perforating components,wherein the perforating components are arranged on the drum surface of the drying drum in an annular form. A piece of gray cloth, which is woven by a normal process, is thoroughly perforated while being dried, so that ironed small holes, which are formed through high-temperature molding, are formed on the gray cloth. According to the scheme, an innovative technology is adopted to manufacture theperforated cloth tape, so that the gray cloth, which is dried, has the ironed small holes which are formed through high-temperature molding; the ironed small hole structure is stable, free from damageand is kept complete, so that effective and high-intensity binding of an injection-molded chain on the cloth tape is guaranteed. According to the scheme, based upon simple transformation of preset holes which are different in diameter and distributing situation of the holes, a beneficial effect of simply regulating and controlling size, spacing and distribution of the ironed small holes; and therefore, the invention is excellent in practicability and application.

Description

technical field [0001] The invention relates to the technical field of zipper tape, in particular to a tape with holes, a method for manufacturing the tape with holes, and a device for manufacturing the tape holes. Background technique [0002] The traditional injection molding zipper tape has a thicker centerline on one edge of the tape, and the injection molded chain elements embrace the centerline to form a bonding force. However, this binding force is weak, and the teeth are easily detached from the centerline of the tape during the zipper test. Aiming at this problem, a main solution at present is to provide a small hole inside the center line, and a reinforcement column will be formed in the small hole when the chain element is injected, which can well avoid the problem of the chain element falling off. At present, the holey cloth tape is mainly realized in the following ways: 1, referring to the disclosed "zipper tooth chain and its manufacturing method" of CN2005100...

AI Technical Summary

Problems solved by technology

[0003] The several technical methods mentioned above all form small holes when weaving the ribbon, and then after the subsequent processes of shaping, winding, dyeing, and drying, the small holes formed by the ribbon in the early stage are squeezed out by other yarns, causing the small holes to be incomplete. stable or disappearing problems

Moreover, at present, only small holes with a single fixed and unchangeable pore size and pore distribution form can be formed, which cannot be adapted to different chain types, and the applicability is not good.
