PURPOSE:To control transfer motion stably and smoothly by controlling the winding speed on the basis of a current command to a motor immediately before receiving of transfer command stored in current memory. CONSTITUTION:A switch 46 is arranged between an adder 39 and a sped control amplifier 35 where the amplifier 35 is constituted as a proportional integration amplifier and upon opening of said switch 46 under fixed dance position control of winding motor 13, the proportional integration amplifier having a capacitor C will function as a current memory of motor 13a to store charges thus to store the current command. Said switch 46 is opened fro the driving timing of winding arm to the time when the travelling material is cut through a knife to perform current control of motor 13a on the basis of a current command stored in the amplifier 35 thus to control the winding speed. |
