An automatic machine for forming induction windings in the axial slots of rotors of dynamo-electric machines, such as electric motors, alternators and the like, comprises a wire-guiding unit for supplying an array of conductor wires to a winding station at which motor-driven take-up means operate to engage the radially innermost ends of the wires, and chuck means for gripping the shaft of the rotor and effecting the operating cycle of forming the windings. The take-up means have associated motor-driven cutting means for cutting the ends of the wires at the end of a cycle, and a member for attachment to the shaft of the rotor to drive the translation and rotation of the take-up means from the chuck means during the forming cycle. The machine also includes automatic motor-driven loading and unloading means for the rotors and electronic means for controlling the wire-guiding unit, the take-up means, the chuck means, the cutting means and the loading and unloading means in a completely automated operating sequence.
