PURPOSE: To prevent untydy winding by determining the optimum turning point through sensing of the space of the drum with respect to the width of wires already wound, and by controlling the pitch in winding with the traverse device, stop and reversing action, and the action of winder.

CONSTITUTION: The number of turns and coiling pitch are obtained from the width of wires wound and the diameter of the wire c and entered in an operator 1 through a rotation setting device 8 and a pitch setting device 3. Rotation of the drum a is sensed by a pulse oscillator 7 while another pulse oscillator 6 controls the drive device 5 so that the coiling pitch given by the traverse device G is held at the set value. The point where the space from the flange part of the drum to the ending part of the wire c becomes below half the diameter of the wire c shall be sensed to change the coiling pitch according to the value of a converter 4, and the stop and reversing actions of the traverse device G are controlled with signals sensed by wire out-of-track sensors B2, C2 and a value of the rotation setting device 8.
