  • 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.
