Abstract

Several methods and machines for continuously forming a fastener product having an array of fastener elements extending from a continuous, sheet-form base, employing a mold belt on which the sheet-form base of the product is formed and from which it is subsequently stripped. The belt defines an array of cavities extending from its outer surface, for molding either the array of fastener elements or an array of preform stems that are subsequently reformed into the fastener elements. In some cases the cavities are blind, such as for forming hook-type fastener elements; in other cases, the cavities extend through the belt, such as for forming mushroom-type fastener elements. Various belt constructions and fastener element shapes are also disclosed.
