Patent ID: 8778243

Claim:
A method of manufacturing sheet-form composite touch fasteners, the method comprising the steps of: providing a longitudinally continuous sheet of a loop material comprising a non-woven web of entangled fibers, the fibers forming both a sheet-form web body having oppositely directed faces and hook-engageable loops extending from at least one face of the web body; introducing the loop material and molten resin to a gap adjacent a mold roll, the molten resin being introduced to the gap in discrete regions between the mold roll and a receiving face of the continuous sheet of loop material, such that the resin is subjected to pressure between the mold roll and the loop material, forcing the resin into cavities defined in the mold roll to form a laminate with a surface having spaced-apart resin-covered regions and exposed regions of the loop material, the resin-covered regions each having a resin base and multiple, loop-engageable fastener elements having stems integrally molded with and extending from the resin base in the direction in which the receiving face is directed, resin of the bases encapsulating fibers of said web body at the receiving face of the loop material in the resin-covered regions, thereby bonding the resin to the loop material; and then cutting the laminate to form said composite touch fasteners, each composite touch fastener having a surface comprising at least a portion of one of the exposed regions of the loop material, and at least a portion of one of the resin-covered regions.
