Based on the calculations of the force components acting on lapping points, the positions of the guide eyes in chain overlapping could be used to determine the safe range that could meet the requirements for tricot overlapping. The safe range can ensure the successful lapping and the multi-guide unit designing in circular warp-knitting machines.展开更多
