发明名称 Method of making a fastener element
摘要 Method of molding plurality of spaced fastener elements onto parallel filaments. A pair of leg portions of each fastening element have, respectively, a projection and an opening, the projection and opening mating to interlock the leg portions. The fastening elements are formed by directing the parallel filaments to a cavity wheel which has mold cavities enclosed by a band, and then injecting plastic material through gate openings in the band into the mold cavities to form a train of fastener elements on the parallel filaments.
