ABSTRACT:
In production of a molded surface fastener with backing, molten resin is extruded to the surface of a die wheel, which has in the surface a multiplicity of engaging-element-forming cavities and, at the same time, the cavities are filled with the molten resin. During that time, the die wheel is rotated to continuously mold a multiplicity of engaging elements on the front surface of the substrate sheet. Meanwhile, the backing sheet is pressed against the rear surface of the substrate sheet on the die wheel by a pressing roller to integrally join the backing sheet and the substrate sheet together at a selected pattern of regions.
