  • Patent number: 11560649
    Abstract: There is provided a method of manufacturing a woven textile, in which a plurality of warp yarns is interlaced with a plurality of weft yarns. A selvedge is formed by interlacing a first subset of the warp yarns with a first subset of the weft yarns and interlacing a second subset of the warp yarns with a second subset of the weft yarns. The first subset of the warp yarns is not interlaced with the second subset of the weft yarns and the second subset of the warp yarns is not interlaced with the first subset of the weft yarns. The method may be used to manufacture a multilayer textile.

  • Patent number: 5172458
    Abstract: The invention relates to the production of non-woven fabrics in which an array of weft threads is created and then combined with a substrate, which may in itself comprise a set of warp threads. In the method according to the invention, the array of weft threads is formed by traversing a weft carrier which has a plurality of weft guides, across the weftspace between two sets of weft retainers. At the end of each traverse, the weft carrier is jogged (that is to say moved in the warpwise direction), so that at the next traverse, it lays a further set of weft yarns across the weftspace, and the weft yarns are hooked around the weft retainers.

  • Patent number: 5099554
    Abstract: The invention relates to the production of non-woven fabrics in which an array of weft threads is created and then combined with a substrate, which may in itself comprise a set of warp threads. In the method according to the invention, the array of weft threads is formed by traversing a weft carrier which has a plurality of weft guides, across the weft-space between two sets of weft retainers (300), (302). At the end of each traverse, the weft carrier is jogged, (that is to say moved in the warpwise direction) so that at the next traverse, it lays a further set of weft yarns across the weftspace, and the weft yarns are hooked around the weft retainers.
