Abstract:
1. A method of making fastener products having an array of male fastener elements formed of resin, the method comprising: providing a mold roll defining an array of cavities extending inwardly from an outer surface thereof, the mold roll positioned adjacent a counter-rotating pressure roll to define a pressure nip; transferring moldable resin into the pressure nip in a pattern defined by rotation of a transfer roll having an outer surface with at least one transfer area relatively raised with respect to another area of the outer surface of the transfer roll, such that the resin is transferred into the nip in a defined region corresponding to the raised transfer area of the transfer roll; laminating the moldable resin to a carrier sheet; pressing the region of resin into multiple cavities of the mold roll in the pressure nip to form at least the stems of the fastener elements, while forming a base of the resin on the surface of the mold roll, the base interconnecting the fastener element stems; and stripping the resin from the mold roll surface on the carrier sheet; wherein the resin is transferred into the pressure nip by first being transferred from the outer surface of the transfer roll to an outer surface of at least one of the mold roll and the pressure roll, and then carried into the pressure nip by rotation of the roll receiving the resin.
