发明名称 Touch Fasteners With Embedded Fibers
摘要 A method of making a touch fastener includes continuously introducing molten resin to a pressure zone at a peripheral surface of a rotating mold roll, such that pressure in the pressure zone forces some of the resin into an array of stem cavities defined in the mold roll to form resin stems while a remainder of the resin forms a base at the roll surface, interconnecting the stems. The method includes forming engageable heads on the stems to form fastener elements and introducing a quantity of discrete, loose fibers to the resin. The fibers pass through the pressure zone with the resin and become individually and separately bonded to the resin to become part of the base.
