Forming touch fasteners on substrates

摘要

A touch fastener strip includes a sheet-form material substrate having a front face, an array of fastener elements integrally molded with a resin base layer on the front face of the substrate and an array of discrete regions of resin (e.g., gripping elements) integrally molded with a resin base layer through apertures in the sheet-form material on the back face of the substrate. The array of fastener elements forms a discrete band of fastener elements extending longitudinally along the front face of the fastener strip, and the array of gripping elements forms a discrete band of gripping elements extending longitudinally along the back face of the fastener strip.

主权项

1. A touch fastener product comprising:
a flexible, sheet-form substrate; a base layer of resin laminated to a first side of the substrate; a multiplicity of fastener elements extending from the base layer, each fastener element comprising a discrete projection with an engageable head, the fastener elements and base layer together forming a seamless resin mass; and a multiplicity of discrete regions of exposed resin each surrounded by an exposed surface of the sheet-form substrate on a second side of the substrate opposite the projections, the multiplicity of discrete regions extending from a single continuous layer of resin laminated to the first side of the substrate.
