Abstract:
1. A method of making a loop fastener product, the method comprising placing a layer of fibers against a first side of a carrier sheet of film, the layer of fibers having an overall density of less than about 5 ounces per square yard and the carrier sheet having an overall thickness of less than about 0.005 inch; needling fibers of the layer through the carrier sheet by piercing the carrier sheet with forked needles that drag portions of the fibers through holes formed in the carrier sheet during needling, leaving loops of the fibers extending from the holes on a second side of the carrier sheet; and fusing the fibers to the first side of the carrier sheet to anchor bases of the loops; wherein the carrier sheet forms projections extending out of a general plane of the carrier sheet at the holes, the projections bearing against fibers passing through the holes.
