Abstract:
A method for continuously manufacturing a surface fastener, comprising:(a) continuously extruding molten resin from an extrusion nozzle having a selected width toward a peripheral surface of a die wheel having a plurality of engaging-member-forming cavities for molding a plate shaped substrate sheet having a selected width, while filling said cavities with a part of said molten resin;(b) continuously introducing a plurality of individual, spaced apart, elongate, continuous fiber filaments into said extruded molten resin downstream of said extrusion nozzle;(c) integrating said fiber filaments with said plate shaped substrate sheet as said die wheel is driven to rotate in the direction of the extrusion of said molten resin, and successively forming a plurality of engaging members integrally on a surface of said substrate sheet; and(d) positively taking up said molded surface fastener after cooling by a suitable means, said fiber filaments preventing the surface fastener from being extended during cutting and/or from being cracked during sewing.
