Abstract:
A method of making a fastener product having a great multiplicity of fastener clements extending from a strip-form base, the method comprising:continuously introducing molten resin to a gap formed along a peripheral surface of a rotating mold roll, such that the resin forms at least a part of the strip-form base of the product at the peripheral mold roll surface and fills an array of fixed cavities defined in the rotating mold roll to form portions of the fastener elements as projections extending from a side of the sheet-form base; whilecontinuously joining a preformed material to the resin forming the sheet-form base, while the resin forming the base is disposed in the gap formed along the peripheral surface of the mold roll and under conditions selected to cause the material to become permanently bonded to the resin of the base and become part of the strip-form base of the product;solidifying the resin; andstripping the solidified resin from the peripheral surface of the mold roll by pulling the projections from their respective cavities.
