Abstract

PURPOSE: To permit a smooth winding by a method wherein when winders are changed over to each other, the winder which has been standing by is started at an optimum point of time, and the speed thereof is substantially synchronized with the shear-cut speed.
CONSTITUTION: In the starting control wherein when a treated mateial 11 is being wound by the first wnder 1, the second winder 3 is started immediately before the completion of said winding, first, the winding length L of the treated material is measured by means of a winding length measuring counter 15, and the difference between the desired winding value L0 and L is detected by means of a planned treated material winding length remainder detecting circuit 16. Then, according to the treating speed V measured in a speed sampling circuit 17, the winding length (V2/2α) from the starting of deceleration to the shear-cut speed VC is calculated in an arithmetic circuit 19. Said value and L0-L1 is compared in a circuit 26 to detect a deceleration timing, and when L0-L=0, the shear-cut instruction is outputted. Then, the second winder 3 is started at a point of time when L0-L≤2.VC2/2α hold in a circuit 23.
