Abstract: PURPOSE:To prevent a rider roll driving d.c. motor from failing and stopping due to overcurrent upon deceleration, by providing a computing circuit for computing an optimum decelerating time in accordance with the speed of the rider roll driving d.c. motor upon initiation of deceleration and the speed thereof after a predetermined time elapses from the time of initiation of deceleration. CONSTITUTION:If a rider roll 4 which is mechanically separated from a paper wind-up roll 1 is decelerated during operation, a first speed detecting circuit 21 detects the speed S1 of the rider roll 4 at the initiation of deceleration, and a second speed detecting circuit 23 detects the speed S2 after a predetermined time t1 elapses from the initiation of deceleration. A computing circuit 25 calculates an optimum deceleration time t3 in accordance with these detected speeds S1, S2 and the detected time t1, and this calculated optimum deceleration time t3 is substituted for the actual optimum deleration time as a set value. Accordingly, the deceleration time may be made to be optimum, and therefore, it is possible to prevent a rider roll d.c. motor 7 from failing and stopping due to overcurrent operation, thereby it is possible to carry out a stable wind-up operation.
