Abstract: Methods and system for allowing the winder to continue to wind armatures and therefore avoid a total loss of production which would otherwise occur during the time which passes between breakage or overflow of the wire and intervention of the operator to restore normal winding conditions are provided. Upon detection of a wire breakage or overflow at a winding position, the wires from flyers corresponding to that position are withdrawn by a withdrawing device.

The affected armatures are transferred to a reject track and new armatures to be wound are subsequently delivered to the winding positions. While the armature in the position where the breakage or overflow was detected remains unwound, the armature in the other position is wound and delivered to the conveyor.
