Abstract

See full text

A method is provided for forming an array of fastener elements extending from a common base. The method includes delivering moldable resin to a mold having a mold surface from which a plurality of fixed mold cavities extend inwardly, each mold cavity having a throat extending from the mold surface and a bowl extending from the throat to a bowl rim, a protrusion of the mold extending into the bowl, thereby filling the mold cavities and forming the common base; solidifying the resin in the cavities to form the fastener elements; and removing the solidified fastener elements from their corresponding fixed mold cavities by pulling the common base away from the mold surface.
