US6694573: Snap with supports
7 Claims, 8 Drawings
This invention intends to provide a snap with supports, the snap being formed of resin across a pair of tapes in a simple manner thereby leading to improvement of productivity and securing a solid structure and practical performance. Supports such as tapes are disposed in parallel with a gap. By using this gap, male bodies or female bodies of the snaps of thermoplastic resin are formed across opposing edges of the tapes opposing each other at a predetermined pitch by injection molding means or extrusion molding means. A string may be used as the support. Different from a conventional processing in which an attaching hole is made in the center of the tape and resin snap is formed therein, a boring step is not necessary. Thus, this snap with tapes is created through such a simple processing.
- 1. Snaps with supports, wherein at least either a plurality of male bodies or female bodies of the snaps composed of thermoplastic resin are attached by integral molding along a pair of supports being composed of long tapes and disposed in parallel opposing each other across a constant gap nipping opposing surfaces of each support at a predetermined pitch and across said gap.
