Abstract
A controller for a winding machine, for controlling the tension of a work running from a feed roller to a winding beam. The controller comprises a speed ratio control unit having a high response speed to control exactly the respective rotating speeds of a feed motor for driving the feed roller, and a winding motor for driving the winding beam during the decelerating operation of the winding machine to maintain the work at a tension substantially the same as a predetermined tension for stationary operation during the decelerating operation of the winding machine. The controller reduces time necessary for stopping the winding machine to the least extent.
