Abstract
A hook and loop type fastener element is provided with a foam backing which seals against a mold wall surrounding a trough which protects the element fastening surface from contact with the foam. A metal strip is positioned behind the foam and is preferably held by an open-mesh scrim secured to the foam and metal strip by hot melt adhesive strips.

An improved fastener assembly for attachment to other objects, and adapted to be embodied in a foamed cushion by being held in a trough in a mold wall during foaming of the cushion, said trough having a predetermined width, said fastener assembly comprising
- a fastener strip having an outer surface comprising one-half of a touch fastening system, said strip having a predetermined width less than the width of the trough;
- a thin foam layer having a front surface attached to the inner surface of said fastener strip, said foam layer having a width substantially greater than the predetermined width of said fastening strip so as to extend a substantial distance beyond each edge of said fastening strip and overlap the edges of the trough;
- an open-mesh fabric layer attached to a back surface of said thin foam layer;
- and
- a metal shim held on to said thin foam layer, said metal shim being adapted to be held in the foam mold by mold-mounted magnets in the bottom of the trough.
