An armature includes a shaft which supports a slotted core and a commutator having peripherally spaced hook-like tangs. The armature is automatically wound on a flyer-type winding machine which incorporates a novel lead forming and connecting mechanism. The mechanism includes a set of finger members each adapted to hook a lead wire extending from a wire coil to a rotating flyer after the winding of the last wire turn for the coil. Each finger member is then rotated approximately 180 DEG for twisting the wire to form a twisted wire loop which is transferred from the finger member to a predetermined tang, forming an alpha-type connection of the lead wire with the tang. A movable wire gripping member is associated with the finger members to control when each lead wire loop is released from a finger member for transfer to a tang, thereby controlling the slack within each lead wire. The finger members and the wire gripping member are also movable as a unit to provide for selecting predetermined commutator tangs.
