Updated: 2018/5/14 16:22:22

Abstract: By capturing the control process of different warp run-in of the closed-loop controlled let-off system at different machine speeds with the SCM01 analyzer and based on the speed switching time of the multi-speed let-off motor obtained from the experiment, the paper analyzes the influence of the warp runin of different patterns on the switching time. The study on the control characteristics of the multi-speed letoff system on warp knitting machine is expected to help improve the responsiveness, control accuracy and stability of multi-speed let-off system and improve the product quality, and provide a theoretical reference for pattern design and improve the weavability of the pattern.
