20140157556 | LAMINATED TOUCH FASTENERS - A method of making a laminated touch fastener includes introducing a flexible substrate to a resin applicator, applying flowable resin to a limited region of a surface of the substrate, and molding the applied resin to form a plurality of defined structures extending from a layer of the applied resin. The substrate surface, as the substrate is introduced to the resin applicator, has a surface characteristic that varies across the surface. The surface includes both a first region and a second region adjacent the first region, the surface characteristic varying to a greater degree within the second region than within the first region.
