PURPOSE:To remove an outside defective part or defective part, in drawing and peeling a deformed wire, by always removing only a fixed thickness of the outside skin though it is of a work with non-round section. CONSTITUTION:A die 10 rotates freely in the surface rectangular to the drawing direction of the work 11 as it is held by a die holder 13. When the work 11 is penetrated into the hole 12 of the die 10, the intended thickness of the outside skin 11a is removed with the drawing. In this case, since the die 10 is fixed in the above-said manner, though the work 11 is twisted partially, it turns in a proper direction according to the twist and the outside skin 11a can be removed easily at an intended thickness. |
