  • Patent number: 9651195
    Abstract: A releasable hanging system having a loop fastener component and a hook fastener component. The loop fastener component includes a flexible patch carrying a field of engageable fibers exposed on a front side of the patch and an adhesive on a back side of the patch. The hook fastener component includes a resin base carrying an array of male touch fastener elements. A significant majority of the male touch fastener elements each extend from the base to a distal tip to overhang the base in a single, common direction. The fastening system can be used to hang an object on a vertical surface such that the male touch fastener elements of the significant majority bear the weight of the object in a downward direction, and such that the significant majority of the male touch fastener elements are oriented so as not to inhibit lifting of the object in an upward direction.

  • Patent number: 8597721
    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.
