PURPOSE:To enable the rolling of a material to be rolled in a off-center state and to perform uniform rolling by providing a 1st driving mechanism with which driving screws on both right and left sides are synchronously revolved in the different direction and a 2nd driving mechanism with which they are revolved in the same direction. CONSTITUTION:By revolving the driving screws 15, 16 forward or backward mutually in the inverse direction with the 1st driving mechanism 13, side guide bodies 11, 12 are slid in the direction of approaching and separating mutually. At this time, the driving screws 15, 16 are allowed to be freely rotatable with the 2nd driving mechanism 14. And, by revolving the driving screws 15, 16 forward or backward in the same direction with the 2nd driving mechanism 14, the side guide bodies 11, 12 are slid in the same direction. When, the driving screws 15, 16 are allowed to be freely rotatable with the 1st driving mechanism 13. In this way, the material to be rolled can be rolled in the various off-center states corresponding to the shape or the like of material to be rolled. |
