Abstract
A weaving machine has a first drive means which has a speed change transmission and drives a warp beam during normal weaving operation, and a second drive means for driving the warp beam independently of the first drive means when the weaving machine is moved by inching or by hand during downtime operation. A first sensor senses the weaving cycle of the weaving machine, and a second sensor senses the warp beam rotation. A warp beam rotation control system determines the angular displacement of the warp beam per weaving cycle during normal weaving operation, and controls the warp beam rotation during downtime operation in accordance with the determined angular displacement per weaving cycle.
