ABSTRACT:
Molten resin is continuously extruded from an extrusion nozzle having a selected width, and at the same time, a plurality of parallel fiber filaments are introduced straightly toward the molten resin outlet in a direction along rotation of a die wheel and/or traversing one or more filaments by a predetermined width. The molten resin extruded from the extrusion nozzle and the filaments are introduced into a predetermined gap for molding a plate-like substrate sheet between the nozzle and the die wheel, which has a multiplicity of hook-forming cavities in its circumferential surface and is rotatable in one direction, and at the same time, the hook-forming cavities are filled with a part of the molten resin. The filaments are embedded in the substrate sheet of the extruded molten resin as the die wheel is driven to rotate in the direction of extrusion of the molten resin, and a plurality of hooks are continuously molded on a surface of the substrate sheet.
