Abstract:
1. A method of making discrete fastener products, the method comprising: providing a rotating mold roll having a peripheral surface, the mold roll defining an array of molding cavities extending inwardly from the peripheral surface, the mold roll being positioned adjacent a pressure device to define a pressure nip, at least one of the mold roll and the pressure device defining at least one molding recess substantially larger than the molding cavities; introducing resin to the rotating mold roll; pressing the resin into the molding cavities to form a multiplicity of discrete projections, and pressing the resin into the molding recess to form a series of discrete, longitudinally spaced apart structural features, the projections and the structural features being carried on a continuous sheet-form base; removing the resin from the mold roll to expose a continuous preform sheet comprising the base, the projections, and the structural features, the structural features being arranged along the preform sheet in a longitudinally repeating pattern; and separating the preform sheet into multiple discrete products, each discrete product including an array of the projections and at least one of the structural features.
