<p>In a molded surface fastener manufacturing method, molten resin (4) is injected or extruded from an injection die (1) or an extrusion nozzle (11), and at the same time, a coarse mesh core sheet (S) is introduced between the extruded molten resin (4) and the circumferential surface of a die wheel (2), which has a multiplicity of hook-element-forming circumferential cavities (5). The core sheet (S) is forced against the circumferential surface of the die wheel (2) by a pressing force of a press roller (13) or under a molten resin pressure at the time of injection or pass part of the molten resin (4) through pores of the core sheet (S) and to fill in the hook-element-forming cavities (5). As a result, a multiplicity of hook elements (4b) are molded, and at the same time, the core sheet (S) is embedded integrally in a plate-like substrate sheet (4a) eccentrically to the hook-element-surface side. <IMAGE></p> |
