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.

In one aspect of the invention, a molding apparatus includes a first cylindrical roll that is rotatably coupled to a frame and an adjacent pressure device, the frame is configured so that a substrate can pass through a nip formed between the first cylindrical roll and the pressure device while a portion of the substrate extends laterally beyond at least the frame and the first cylindrical roll.

Abstract: Methods of forming a loop product are provided. Methods include needling polymeric fibers through a substrate to form hook-engageable loop structures of the fibers extending from one surface of the substrate and then using heat and pressure to soften and bond polymer of the fibers directly to the substrate and adjacent fibers, thereby anchoring the loop structures to resist fiber pullout under fastening loads. Loop products are also provided.

Abstract: Touch fastener products (10) are made by distributing a multiplicity of discrete fastening bits (14, 14a, 14b) over a support surface (12) and fixing the distributed bits (14, 14a, 14b) to the support surface (12), such as by an adhesive (32). Each bit (14, 14a, 14b) has opposite side surfaces (24, 24b, 26, 26b) forming boundaries of surfaces defining projections (16) extending in different directions from the fastening bits (14, 14a, 14b), at least one of the opposite side surfaces (24, 24b, 26, 26b) being non-planar, and each projection (16) has an overhanging head (18). As fixed, each bit (14, 14a, 14b) is oriented with at least one of its projection heads (18) raised from the support surface (12) to releasably engage fibers (30). Bits (14, 14a, 14b) are made by pelletizing shaped rails (36). Applications include securing floor coverings (150).

Abstract: A releasable fastening features a first fastening strip including an elongated, flexible base carrying an array of discrete fastener elements arranged in rows and columns, and a second fastening strip configured to releasably engage with the first fastening strip. The first fastening strip also includes a longitudinally continuous rib supported by the upper surface of the base of the first fastening strip, the rib extending sufficiently far from the base of the first fastening strip to engage a sealing portion of the second fastening strip, and of a bending strength sufficiently low that the rib is placed in an elastically bent state, when the first and second fastening strips are in the engaged state, thereby forming with the sealing portion of the second fastening strip a non-interlocking barrier to resist flow across the fastening with the first and second fastening strips in the engaged state.

Abstract: A touch fastener product has a base strip of resin carrying both mechanical fastener projections and adhesive, in some cases disposed on raised portions of the base strip. The fastener projections are arranged in discrete fields with lanes between the fields, and the adhesive is disposed within the lanes. The adhesive in each lane is shorter, as measured perpendicularly from the base strip, than the projections nearest the lane, by a distance that is less than ten percent of the width of the lane. In some cases molded stems extend through the adhesive in the lanes. The fastening face of the molded base strip is treated to give the fastening face a higher surface energy than the back face, to resist adhesive delamination during unspooling.

Abstract: A laminated touch fastener is made in a continuous process on a mold roll. Flowable resin is pressed against the mold roll in limited areas to form projections extending from resin layers that are laminated to a flexible substrate while carried on the mold roll. In one example a continuous channel about the mold roll is positioned such that the resin at least partially fills the channel as the layers are formed, thereby forming in the channel a raised portion in which the resin layer is of a greater thickness than at a point between the projections and the raised portion. In another example, grooves in the mold roll receive ribs of a pressure applicator during forming of the layers, the ribs blocking lateral flow of the resin to form a desired edge profile.

Abstract: A foam roofing underlayment is provided with a reinforcement membrane having an array of fastener elements for engaging fastener elements on a flexible roof membrane. The underlayment is formed by molding foam between the reinforcement membrane and a carrier membrane. The underlayment in secured to the roof using washers having fastener elements for engaging the fastener elements of the flexible roof membrane.
