Abstract
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. The flowable resin may be applied within the first region such that an edge of the resin layer is disposed within, and adjacent an exposed portion of, the first region of the substrate surface.
