摘要： A touch fastener has a base and an array of discrete fastener elements each extending from the base and together forming with the base a contiguous mass of resin. Each discrete fastener element includes a stem rising from the base, and a head overhanging the base from a front side of the stem to a distal edge, the front side of the stem, an underside of the head, and an upper surface of the base together forming, in side profile, a generally curved retention space boundary surface such that the boundary surface forms, at its innermost extent, a retention cavity defined between curvature discontinuities spaced from both the base and the distal edge.

摘要： 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.
