Abstract
PURPOSE: To arrange the side edges of a coil of such as paper or band steel wound by a rewinder and prevent the coil from being creased near a winding core, by controlling the back tension depending on the diameter of the coil.
CONSTITUTION: The armature current of a brake motor M1, which drives an unwound coil D1, is controlled by a control amplifier CA and a power amplifier PA to obtain a desired torque. Current reference signals e3, e4 for the speed-changing torque and the mechanical loss are previously generated by a speed change compensation signal generator ACC and a mechanical loss compensation signal generator LOS, respectively. The torque correponding to the back tension is indicated by a pontentiometer PM1 and is varied depending on the diameter of the wound coil D4 by a potentiometer PM2 for detecting the diameter of the wound coil.
