Abstract (en)

There is provided a method for controlling winding of a woven cloth (8) in a loom, wherein the cloth 88) delivered through a surface roller (2) is wound on a cloth roller (9) driven by a take-up motor (16) whose torque is controllable. The method includes the steps of setting a change command torque (21) that progressively increases or decreases a torque of the take-up motor (16), driving the take-up motor according to the change command torque (21) after setting the change command torque, detecting variation of rotation speed of the take-up motor (16), calculating load torque based on the change command torque (21), calculating winding torque based on tension and winding diameter of the cloth (8), calculating winding control torque by adding the load torque and the winding torque, and driving the take-up motor (16) according to the winding control torque. There is also provided an apparatus for winding of a woven cloth in a loom by the above-described method.
