Abstract
There is provided a driving mechanism of a compound knitting needle in a narrow width crochet knitting machine, which can highly accurately control an operation timing and stroke of a compound knitting needle comprising a hook-like knitting needle and a needle-like slider even in an operation at a speed higher than a conventional case without generating jumping or an error in its operation. A needle bar driving mechanism reciprocates a needle bar fixing and supporting base end portions of the plurality of hook-like knitting needles via a first rod at a desired timing, and comprises a rotary member supported on a main rotary shaft, and a first rod having one end rotatably attached to the needle bar and the other end rotatably attached onto a position which is eccentric from the rotary axis of the rotary member. A slider bar driving mechanism reciprocates a slider bar fixing and supporting base end portions of the plurality of sliders via a second rod at a desired timing, and comprises a rotary cam supported on the main rotary shaft, and the second rod (21) having one end having a cam follower and the other end rotatably attached to the slider bar.
