ABSTRACT OF THE DISCLOSURE A method and apparatus are disclosed for reforming the initial shape of an approximately loop-shaped starting piece into a final prescribed loop-shape. A plurality of elongated materials such as wire rods are arranged in parallel at prescribed intervals to define a prescribed looped or cylindri- cal space having a first diameter. A plurality of pressing means such as pressing plates actuated by cylinders and pistons press free ends of the elongated materials to reduce the diameter of the looped spare prescribed by the elongated materials to define a reduced looped space having a second diameter smaller than the first diameter. The free ends of the elongated materials are then inserted within the starting piece. The pressing means are retracted, whereby the free ends of the elongated materials contact the inner surface of the starting piece. A control piece moved in the direction of elongation of the elongated materials is moved to the free ends of the elongated materials within the starting piece, thereby pressing the free ends against an inner surface of the starting piece to reform the shape of the starting piece to the final prescribed loop shape.
