Abstract
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.
Claims19
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.
A garment tab comprising:
- a flexible tab substrate having at least partially exposed opposite side surfaces;
- a base layer of resin covering a portion of a first side of the tab substrate and carrying a multiplicity of touch fastener elements extending from the base layer, each touch fastener element comprising a discrete projection with an engageable head, the fastener elements and base layer together forming a seamless resin mass;
- and
- resin gripping elements disposed on a second side of the tab substrate, each resin gripping element surrounded by exposed substrate and comprising resin contiguous with a single continuous layer of resin disposed on the first side of the tab substrate and connecting multiple gripping elements.
