The loop forming process of compound needle warp knitting machine can be divided into three stages: unwinding, padding, closing, looping, bending, unwinding, loop forming and drawing. At the beginning of the loop forming process, the needle body rises before the needle core to make the old loop retreat from the needle hook to the needle bar, the needle body rises to the highest point and then falls down, the yarn guide needle surrounds the needle pad yarn, at the same time, the needle hook takes new yarn, after the needle core and the needle body are closed, the needle body and the needle core continue to fall, the old loop rises along the needle tongue and slides onto the new yarn, and the new yarn bends to form a loop, The sinker then pulls the settling arc formed by the new yarn to complete a loop forming cycle

Let off mechanism is used to unwind the warp yarn on the warp shaft and send it to the knitting area. There are two types: negative and positive. In the negative mechanism, the warp shaft is pulled by the warp tension to send out the warp, so it does not need a special warp shaft transmission device. It is suitable for warp knitting machines with low machine speed and complicated let off law. The positive let off mechanism uses special transmission device to make the warp shaft rotate to send out the warp, which is different from the tension induction type and the linear speed induction type. The tension induction mechanism controls the speed of the warp shaft by the tension bar to sense the warp tension. The linear speed induction mechanism controls the rotation speed of the warp shaft by sensing the warp speed with the speed measuring device. This kind of mechanism is widely used in high-speed warp knitting machines because it can feed the warp at a predetermined linear speed and work stably at high speed.

The function of the draw take-up mechanism is to draw the fabric out of the weaving area at a predetermined speed and wind it into a cloth roll.
