  • Publication number: 20060053997
    Abstract: The cutting device is equipped with a feeding device (10) for a warp-knitted fabric (4). The warp-knitted fabric has at least two warps (6), between which floating weft yarns (8) are placed. The cutting device is also equipped with a cutting implement (22) for cutting through the weft yarns (8) and with a leading away device (24) for the severed warps (6) that serve as effect yarns. In order to improve the cutting device, the cutting implement (22) comprises guide elements (32, 34) with projecting guide edges (36, 38) serving to support the weft yarns (8) to be cut. The guide edges (36, 38) form a gap (40) between them into which a rotating blade (42) extends. The guide elements (32, 34) also contain, on the sides facing away from the guide edges (36, 38), rebouncing guide surfaces (44, 46) for the warps (6).

  • Patent number: 6182476
    Abstract: The invention relates to a warp knitting loom with individually driven guide bars that are controlled by a control device. A linear motor is used, resulting in a particularly space-saving and flexible driving apparatus. This motor has at least two driving elements which are each connected to a guide bar and can move back and forth in a common stator with a closed magnetic circuit. Each driving element has at least one drive coil which is connected to the control device and whose winding plane is transversal to the magnetic flux.
