Abstract:
A flat bed knitting machine wherein a large number of needles having a hook rear and a hook face are held on each of a first lower needle bed and a second lower needle bed in such a way that said needles can be advanced and retracted, the first needle bed and the second needle bed are arranged to oppose each other with a trick gap between them, said trick gap having a trick gap center line, said first lower needle bed and said second lower needle bed can be racked relatively to each other, and an upper bed holding a large number of transfer members is provided in such a way that said transfer members can be advanced and retracted over at least one of the first and second lower needle beds, characterized in thatto transfer a stitch loop held on a transfer member of the upper bed to a receiving needle of one of the first and second lower needle beds, the flat knitting machine is further provided witha transfer member control means for shifting first the transfer member away from the receiving needle and then advancing the transfer member towards the receiving needle, said transfer member control means has a transfer member control cam reciprocating over the upper bed, said transfer member control cam comprisesa first cam means for advancing first the stitch loop held on said transfer member to a position beyond the trick gap center line and then retracting the stitch loop anda second cam means for positioning first the stitch loop held on said transfer member in a position short of the trick gap center line and then advancing the stitch loop, anda needle control means for advancing the receiving needle towards the transfer member in synchronization with the advancement of said transfer member towards the receiving needle, said needle control means hasa means for, in synchronization with said first cam means, advancing the hook rear of said receiving needle to a position where the hook rear is in the stitch loop when said stitch loop is in a position beyond the trick gap center line and advancing the hook face of said receiving needle into the stitch when the stitch loop is retracted, anda means for, in synchronization with said second cam means, advancing the hook rear of said receiving needle to a position where the hook rear is in the stitch loop when said stitch loop is retracted to a position short of the trick gap center line and advancing the hook face of said receiving needle into the stitch loop when the stitch loop is retracted.
