Stitch Formation Cycles

At the beginning of the process, the needle is positioned on the knock-over plane with the loop thread inside the hook, closed by the latch.

The upstroke motion of the needle makes the thread slip downward touching the latch; this makes the latch rotate anticlockwise and open the hook.

Once the needle has reached its maximum height on the looping plane, the latch opens wide and the stitch moves along the stem.

The needle now begins to move downward. On reaching the tuck-stitching plane, it catches a new loop thread.

In the further downstroke of the needle the stitch already formed touches the latch, making it rotate clockwise. As the needle continues its downward motion, this stitch begins closing the latch on the hook.

The needle reaches the end of its stroke (i.e. its lower point) and the previous stitch, after having closed the hook completely, is knocked over on the new loop forming a new stitch. Picture 13Add Content...

The needle moves upward and the loop thread, originally inside the spring beard, moves along the stem.

Once the needle has been fed, the thread is introduced inside the spring beard, by means of an external device; at this point, the presser closes the spring beard.

While the needle is in the non-knitting position, the stitch can move on the hook. Then, when the needle begins to move downward, it slides on the hook and knocks over on the new yarn fed at the end of the stroke.

The hook is opened by the upward motion of the needle and by the insertion of the slide in the groove on the stem; the stitch moves on the stem, going below the tip of the slide.

The needle, now completely open, is fed with new thread and then starts to move downward. The slide moves with a certain delay in relation to the needle and this makes the hook close and the previous stitch to be knocked over on the new thread.
