Abstract

See full text

A surface fastener engaging member manufacturing method includes: extruding from an extrusion nozzle a predetermined width of molten resin; introducing the molten resin into a predetermined gap between the extrusion nozzle and a die wheel to fill up coupling element molding cavities with the molten resin as the die wheel rotates in one direction; continuously molding a multiplicity of coupling elements integrally on the front surface of a continuous board-shaped base layer as the die wheel is rotated; applying a porous backing material to the base layer under pressure while the base layer is moved in response to the rotation of the die wheel; cooling the die wheel to a predetermined temperature; and positively pulling the base layer with the backing material attached thereto as cooled, from the die wheel as the molded coupling elements of the engaging section are removed off the coupling element molding cavities.
