In production of a molded surface fastener with backing, molten resin (4') is extruded to the surface of a die wheel (2), which has in the surface a multiplicity of engaging-element-forming cavities (2a) and, at the same time, the cavities (2a) are filled with the molten resin (4'). During that time, the die wheel (2) is rotated to continuously mold a multiplicity of engaging elements (4b) on the front surface of the substrate sheet (4a). Meanwhile, the backing sheet (3) is pressed against the rear surface of the substrate sheet (4a) on the die wheel (2) by a pressing roller (5) to integrally join the backing sheet (3) and the substrate sheet (4a) together at a selected pattern of regions (AP). <IMAGE> |
