ABSTRACT:
The invention relates to fastener molding. In one aspect, a molding apparatus for forming a sheet-form fastener product includes a first ring defining a plurality of voids extending inwardly from a circumferential surface of the ring. The voids are circumferentially spaced apart from one another by portions of the ring including recessed regions that partially define molding cavities. The molding apparatus also includes multiple plug members configured to be disposed within the voids. The plug members and the portions of the ring therebetween cooperate to define the molding cavities when the plug members are disposed within the voids. The molding cavities are shaped to mold, from molten resin forced into the molding cavities from a peripheral surface of the molding apparatus, an array of fastener elements having overhanging heads for releasable engagement with a mating fastener product.
