(54) Stitch increasing method


(57) A latch needle (FB) on a front needle bed having a stitch (fb) in a hook thereof is advanced until the stitch (fb) is moved beyond a latch to the outside of the hook and, simultaneously a latch needle (BA) on a rear needle bed opposing thereto is advanced to allow a stitch (fb1) to be yarned over a hook of the latch needle (BA). Subsequently, the latch needle (BA) having the stitch (fb1) yarned over the hook is retracted to a retracted position while stopping the latch needle (FB) at its mid position to maintain the stitch (fb) in a state of being yarned on the outside of the hook without moving beyond the latch, whereby the stitch (fb) is doubled. Subsequently, the latch needle (FB) and a free needle (BZ) are advanced to transfer the stitch (fb) to the free needle (BZ).
