A surface fastener engaging member manufacturing method comprises: extruding from an extrusion nozzle a predetermined width of molten resin; introducing the molten resin, which is extruded from the extrusion nozzle, into a predetermined gap between the extrusion nozzle and a die wheel, which has a multiplicity of coupling element molding cavities on its circumferential surface and a cooling unit inside, to fill up the 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 in such a direction as to extrude the molten resin; applying a porous backing material, which is supplied separately from the molten resin and adjacently to the extrusion nozzle while being heated, to the board-shaped base layer under pressure while the board-shaped base layer is moved in response to the rotation of the die wheel; cooling the die wheel to a predetermined temperature; and positively pulling a resulting engaging section, which includes the board-shaped base layer with the backing material attached thereto as cooled, from the die wheel in the molten resin extruding direction as the molded coupling elements of the engaging section are removed off the coupling element molding cavities. |
