1469040 Sliding clasp fastener stringer tapes YOSHIDA KOGYO KK 5 Feb 1975 [7 Feb 1974] 4864/75 Heading E2S A sliding clasp fastener stringer tape 10 which is made of fabric at least partly including synthetic fibres, or filaments, and which has at least one end formed by severance of the stringer tape from a continuous length of such tape is characterised in that the synthetic fibres, or filaments, are thermally fused together in a plurality of regions 12 at the, or each, severed end portion of said stringer tape to prevent the unravelling of the fabric, the regions 12 being spaced apart from each other in the transverse direction of the stringer tape. The tapes 10 are preferably formed of woven fabric such that its warp and weft are both comprised of yarns composed of synthetic fibres, or filaments, or, blends of the latter with other fibres, or filaments. Alternatively, either the warp or weft, may be synthetic or, partly synthetic. The thermally fused regions can be formed by high frequency, or ultrasonic, welding and are preferably elongated in the longitudinal direction of the tape. |
