Abstract
When a new yarn is received by a hook to form a new stitch loop, to prevent old stitch loops from going beyond the top end of the slider and being knocked over, the advanced position of the slider into the trick gap is maintained, and the new stitch loops are pulled into the old stitch loops. Next, the hook of a compound needle of the opposing needle bed is inserted into the old stitch loop, and said slider is lowered and retracted, and at the same time, the old stitch loops are transferred onto the hooks of the opposing needle bed to make split knit.
Claims9
A stitch forming method using a flat knitting machine wherein said machine includes
- at least a pair of needle beds, one in a front and an other in a rear, an area between said needle beds constituting a trick gap, each of the needle beds having a plurality of compound needles, each compound needle comprising a needle proper having a hook at a top end thereof and a slider having two elastic plates each having a tongue at a top end thereof, the needle proper and the slider being individually slidable forward to and backward from the trick gap, the tongues opening and closing the hook, and with advancement of the tongues beyond the hook, said two elastic plates being opened by said hook, and a yarn feeder to feed yarn to the hook of each said compound needle,
- said stitch forming method comprising:
- advancing, to the trick gap, a hook and tongues of a first compound needle of said plurality of compound needles of a first needle bed of said pair of needle beds, said first compound needle holding at least one first stitch loop;
- and
- feeding a first yarn from the yarn feeder to the hook of the first compound needle, retracting said hook for holding said first yarn on the hook, and keeping said tongues in the trick gap for holding said first stitch loop on said tongues without knocking over the first stitch loop from the first compound needle.
A flat knitting machine comprising:
- at least a pair of needle beds, one in a front and an other in a rear;
- a trick gap between said needle beds;
- a plurality of compound needles, each comprising a needle proper having a hook at a top end thereof and a slider having two elastic plates each having a tongue at a top end thereof,
- wherein each needle proper and each slider are individually slidable in the needle beds forward to and backward from the trick gap, each needle proper is provided with a needle proper butt, each slider is provided with a slider butt, the tongues are to open and close the hooks, and with the advancement of the tongue beyond the hook, said two elastic plates are opened by said book;
- at least a yarn feeder for feeding a yarn to the hooks;
- and
- a carriage having a knitting lock comprising a needle cam lock and a slider cam lock provided on the trick gap side of the needle cam lock and working on slider butts for advancing and retracting the sliders,
- wherein said needle cam lock comprises a raising cam working on the needle proper butts for advancing hooks to the trick gap;
- and knitting cams arranged on both sides of the raising cam for retracting the hooks, and
- wherein said slider cam lock is provided with a first slider butt track engaging with the slider butts for keeping the tongues in a position beyond the hooks and making the slider butts pass through the knitting lock so that loops on the sliders are not knocked over during retracting the hooks from the trick gap and said slider cam lock guides said slider butts into a subsequent knitting lock.
