Title:
CONTROL OF WARP YARN FEED IN LOOM
Document Type and Number:
Japanese Patent JPS59100746
Kind Code:
A
Abstract:
A method of regulating the tension of warp yarns in a weaving machine is disclosed herein. In a preferred embodiment of the invention, variation in warp yarn tension is detected by a tension roller which is movable with a change in the tension. The speed at which a warp beam is rotated is controlled in dependence upon the manner of the tension roller movement in such a way that its unwinding rotation during normal weaving operation of the machine is speeded up with an increase in the warp yarn tension and slowed down with a decrease therein, and also that its rewinding rotation during reversing operation of the machine is decelerated with an increase in the warp yarn tension and accelerated with a decrease in the tension.
