Molding Hook and Loop Fastener

A method for manufacturing a molding hook and loop fastener which is molded integrally with a foam body at the same time as molding of the foam body, including:

• a planar substrate made from a thermoplastic resin including a first surface and a second surface opposite to the first surface;
• barriers erected on the first surface near left and right side edges along a length direction of the substrate;
• a plurality of engaging elements disposed between the left and right barriers;
• and
• lateral wall portions disposed along a width direction on the inside of the barriers, wherein:
• a molten resin is poured toward a die wheel in which molding cavities are provided on the circumferential surface for molding at least the lateral wall portions and the engaging elements to form the substrate as well as the lateral wall portions and the engaging element,
• the molded hook and loop fastener having the molded substrate, lateral wall portions and engaging elements are teared off from the circumferential surface of the die wheel, and
• upper end portions of the lateral wall portions of the molded hook and loop fastener which is teared off with a press roll to form a flat upper surface portion on the lateral wall portions.
