ABSTRACT:
A molding apparatus for forming a sheet-form fastener product includes a mold roll that is rotatable about an axis of rotation and has a circumferential surface defining a plurality of apertures that extend inwardly from the circumferential surface. Multiple inserts having first and second ends are retained within corresponding apertures of the mold roll such that the first end of each insert is directed toward the circumferential surface of the mold roll. The inserts have surfaces that at least partially define blind molding cavities shaped to mold, from molten resin forced into the molding cavities from the circumferential surface of the mold roll, an array of fastener elements having overhanging heads for releasable engagement with a mating fastener product.
