Slide fastener with separable bottom stop assembly and method of manufacturing the same

摘要

A slide fastener in which an insert pin and a box pin of a separable bottom stop assembly made of synthetic resin are molded integrally along side edges of fastener tapes. The insert pin and the box pin have peripheral shapes allowing themselves to be inserted into element row guide grooves of a slider, and are molded integrally such that the entire insert pin and the box pin incline toward rear face sides of the respective tapes from their inner side edges to outer side edges relative to tape planes of the fastener, said rear face sides having no core threads of the core portions. Thus, resin layers having substantially even thickness can be formed on both the front and rear face sides of the core portions so that the resin layers never peel away from rear surfaces of the fastener tapes, and the core portions and their peripheries never become brittle.
