Warp knitting transverse moving device and warp knitting machine

Abstract

The present application discloses a warp knitting traverse device and a warp knitting machine. The warp knitting traverse device includes a faceplate and a comb. The cross-section of the faceplate is an annular shape with different outer diameters, and the annular shape is divided into x number of equal parts, courses, along the circumferential direction and wherein 2≤x≤8; on the outer surface of the faceplate, at least two slopes are formed between adjacent courses. The present invention utilizes this new structural design, and designs a gradually gentle slope for buffering for the comb movement, allowing the comb to move step by step, which can avoid the instability caused by sudden large span, and is conducive to achieve high precision and smoothness in using a warp knitting machine in the process of fabric production. The new improvement preserve the machine for continuous production and achieve high throughput.
