  • Patent number: 6151923
    Abstract: An apparatus for supplying a multi-layer, multiaxial yarn stratum to the knitting site of a warp knitting machine, with endless conveyor chains for guiding the yarn stratum to the knitting site, with at least two multiple yarn guides, which can be moved changeably over both conveyor chains for each yarn sheet and with means for supporting the yarn stratum. The prelaid yarn stratum is supplied in such a manner, that at least one endless conveyor belt is driven synchronously with the conveyor chains and supports the yarn stratum, and is guided over guide rollers mounted on the frame with the distance between the guide roller and the knitting site bridged with the help of supporting guiding elements for the yarn stratum.

  • Patent number: 4638647
    Abstract: A flat-weft knitting machine for producing a weft-and-warp-knit fabric, e.g., a stitch knitting machine, employs a weft yarn insertion device, which moves backward and forward, for constantly guiding a continuous thread or yarn group. The insertion device transfers one weft yarn group of the yarn group to first and second weft yarn conveyor means. The weft yarn group is then separated from the insertion device and the yarn group. The weft yarn group thus has free ends at both ends and is then conveyed by the weft yarn conveyor means to a looping point, for connection with loop-forming warp yarns to form a fabric.
