Patent ID: 7056462

Claim:
A method of making a fastener product having discrete regions of fastener element stems extending from a strip-form base, the method comprising: providing a gap formed along a peripheral surface of a rotating mold roll, the mold roll having a plurality of cavities exposed about the peripheral surface; introducing a sleeve to the gap, the sleeve positioned about the mold roll and covering selected ones of said plurality of cavities; continuously introducing molten resin to the gap such that the resin forms at least a part of the strip-form base of the product at the peripheral mold roll surface and at least partially fills a plurality of the cavities to form fastener element stems as projections extending from the strip-form base, while the resin remains blocked from said selected ones by the sleeve; solidifying the resin; and stripping the solidified resin from the peripheral surface of the mold roll by pulling the projections from their respective cavities.
