A method and apparatus for automatically twisting two ends of a wire protruding from a stack of rotor lamination parts employs a holder for holding and positioning the parts stack. A rotatable collar is provided having an aperture through which the two ends of the wire project. A rotating and reciprocating substantially conically-shaped head traps the wire ends between an inner edge of the rotating collar facing the conically-shaped head and the conically-shaped head when the conically-shaped head is thrust into position against the inner edge of the collar. A unit is provided for positioning the conically-shaped head against the inner edge of the collar. A rotating member rotates the conically-shaped head to twist the two ends of the wire. During twisting, clamping jaws clamp a portion of the twisted ends while the conically-shaped head continues to rotate so that a scrap portion of the twisted ends is broken off by wire fatigue and can fall free when the conically-shaped head is moved away from the inner edge of the rotating collar.
