Abstract: Based on a high-speed warp-knitting machine with two guide bars, this paper analyzed the requirements on the movement mode and size of the guide bars and their relationship with the lapping process. The principle of realizing the designed movement by using multi-stage serial planar linkage was studied. By using a practical example, the designing process was explained and the movement results of the guide bar swinging mechanism were analyzed.

Key words: warp-knitting machine; guide bar; linkage
