Abstract

See full text

A process and apparatus for producing fastener elements comprising a base and a field of fastener elements molded with and extending from the base. The method includes applying molten resin under pressure to the surface of a mold roll, the mold roll consisting of a pair of adjacent molding rings. A first molding ring defines cavities that form base portions of the fastener elements and serve as channels allowing molten resin to pass through and into cavities defined by a second molding ring thus molding distal portions of the fastener elements. The fastener elements are constructed to engage loops of a mating loop component to form a releasable fastener. The fastener elements comprise hooks and spikes, interspersed among the hooks, which extend at an acute angle from the base. By arranging the hooks and spikes in differing directions on the base, increased shear strength is provided in corresponding directions.
