Abstract

See full text

A fastening connector of thermoplastic resin for connecting two separate members together is continuously molded efficiently in a single step by a simple method and apparatus. The method includes the steps of continuously extruding molten resin from an injection nozzle to the circumferential surface of a die wheel, which has in the circumferential surface, a multiplicity of engaging-element-forming cavities, to continuously mold a substrate sheet between the circumferential surface of the die wheel and the injection nozzle and a multiplicity of engaging elements in the engaging-element-forming cavities which elements stand on a front surface of the substrate sheet and, at the same time, to continuously mold at least one engaging ridge, through an engaging-ridge-molding channel, with part of the molten resin integrally with a rear surface of the substrate sheet.
