Abstract: A cutter mounting bar (18) is attached between both left and right side walls of an outer shield (16) in an armature winding apparatus to be swingably rotatable, and it is biased in a direction in which a movable blade (21) provided integrally with a tip end portion is away from an axis X by a compression spring (19). When an inner shield (15) is rotated, a cam surface presses an adjustment screw (23) outward to swing a cutter mounting bar (18) in a direction in which the movable blade (21) approaches the axis X. In this state, when an armature (1) is rotated and a wire (7) connecting a hook wire connection portion and a gripper (30) is inserted between the movable blade (21) and a backing blade (22) to advance the outer shield (16) rightward, the backing blade (22) abuts against a groove bottom surface of the inner shield (15) and stops, and only the movable blade (21) advances rightward and severs the wire (7) at a position close to the hook wire connection portion.

Abstract: A flyer shaft (12) having a first axis (A), and a wire guide holding member (24) having a second axis (B) eccentric therefrom by a distance (D) are synchronized to rotate in a same direction at a same speed, while an eccentric flange (26) supported around the fist axis (A) and the second axis (B), and a wire guide (30) integrated therewith are kept stationary, and after a wire (5) is inserted through a center hole (18a) of a push rod (18), which is formed in a center portion of the flyer shaft (12), and then passed through middle rollers (19, 20) and a top roller (21), it is guided by the wire guide (30) to be wound around an iron core (4) of an armature (1).
