[0002] Warp knitting machine is a kind of textile machinery for producing knitted fabric, and it is mainly composed of a weaving mechanism, a guide bar transverse motion mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism. The basic principle of warp knitting machine is that one or several groups of parallel yarns are fed into all working needles of the machine simultaneously, and then they are knitted into loops to form a knitted fabric.
