Patent ID: 7601284

Claim:
A method for forming a fastener product having multiplicities of fastener elements extending from a strip form base, the method comprising: folding a sheet material about a first longitudinal fold line to form a first longitudinal edge portion overlapping only a first adjacent portion of the sheet material, leaving another portion of the sheet material exposed as a primary remainder portion; continuously introducing the folded sheet material to a gap defined adjacent to a peripheral surface of a rotating mold roll, while introducing moldable resin between the sheet material and the mold roll, such that the resin fills a field of fixed cavities defined in the rotating mold roll to form a field of molded stems bonded to one of the first longitudinal edge portion and the primary remainder portion such that the molded stems are formed over the sheet material and extend outward over the sheet material, while introducing an additional material to the gap, such that the additional material is bonded to the other of the first longitudinal edge portion and the primary remainder portion; forming engageable heads on the molded stems; solidifying the resin; and then stripping the solidified resin from the peripheral surface of the mold roll by pulling the stems from their respective cavities.
