A method of forming a basket shaped article from a plurality of metal bars secured together in a parallel relationship comprises securing one end of the said plurality of metal bars in a fixed gripper ring and securing the other end in a rotatable gripper ring. The rotatable gripper ring is rotated in one direction to impart a twist to the bars. It is then rotated the opposite direction to partially untwist the bars. The initial twist is greater than 360 DEG . <IMAGE> |
