细纱机依纳V型牵伸机构的优化改进

The improvement of the V type draft system on spinning frame

对细纱机常采用的依纳V型牵伸机构进行了优化改进。通过在后牵伸区增加一附加压力棒消除反包围弧,从而提高牵伸效果,并对其产生的毛羽增多的弊病采取了建议性措施。

A new method is designed to improve the V type draft system. A pressure-bar is put on the back drafting zone so as to remove the back-surrounded arc and to make more uniform drafting. It also gives a good method to reduce the hairness.
