PURPOSE:To straighten a wire rod to a straight shape and to deliver the wire rod under the thrust force applied thereto by disposing plural freely rotatable straightening dies within a rotary supporting member, inclining alternately axial centers thereof in opposite directions or shifting alternately the axial center positions and revolving and rotating the dies. CONSTITUTION:Freely rotatable straightening dies 5 consisting of plural bearings 41 are disposed within a rotary supporting member 2 and the axial centers thereof are alternately inclined to 5-15 deg. in the case of a hard steel wire and 10-20 deg. in the case of a mild steel wire. The thrust force F and thrust velocity V expressed by the equation I and the equation II are applied to a wire rod by the revolution and rotation of the dies 5. The wire rod is thus straightened to a straight wire without having flawing by bending and is successively and automatically delivered. The similar effect and operation are obtd. as well even by shifting alternately the axial centers of the straightening dies. |
