A method for forming a double-sided loop strap includes: receiving a continuous longitudinal strip of loop material including a strip-form base bearing a field of upstanding loops on a fastening side of the strip bounded by opposite longitudinal edges, folding each of the longitudinal edges away from the fastening side, such that the base overlaps itself, and securing the folded edges in place by permanently bonding together overlapped areas of the base to form the double-sided loop strap.

Double-sided fasteners

A cinching device includes: a buckle including a frame defining an opening; an elongate flexible strap coupled to one portion of the frame and extending away from the frame to a freestanding distal tongue receivable by the opening of the frame, the strap including a first face carrying a plurality of loop-engageable discrete fastening elements and an opposing second face carrying a loop material; and a tab coupled to another portion of the frame, the tab including an exposed touch fastening face engageable with at least one of: the plurality of fastening elements of the first face of the strap or the loop material of the second face of the strap.

Cinching with touch fastening straps

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.

Laminated touch fasteners

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.

Forming laminated touch fasteners

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.
