  • Patent number: 4006758
    Abstract: A Shuttleless Narrow Fabric Loom is provided with a weft inserting means, to insert filling in the warp sheds, there being two weft threads for each insertion. In order to retain the inserted weft threads in the shed and to form a proper selvage, a knitting needle is provided on the opposite side from the inserting means to engage the inserting member to acquire the weft as the inserting member is withdrawn. The needle which has caught the weft retracts in the direction of the warp flow until it casts off the weft previously acquired. During the knitting cycle, the weft is engaged next to the selvage adjacent the knitting needle to draw a measured loop of weft.
