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; extruding moldable resin in discrete doses through an orifice defined in an outer surface of a rotating die wheel; transferring the extruded resin into the pressure nip in such a manner that the resin is transferred into the nip in discrete regions corresponding to the doses of extruded resin; laminating the moldable resin to a carrier sheet; pressing the regions 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 carried into the pressure nip on the carrier sheet; and wherein the carrier sheet passes through a nip defined between the die wheel and a counter-rotating roller.
