下させる等の点については配慮されていなかつた。In the conventional apparatus, as described in JP-A-54-65156, a suction nozzle is provided near the straightening roll to correct the scale generated during straightening while absorbing dust. However, since the gear gap between the suction nozzle and the material to be straightened is slightly controlled, the material to be straightened comes into contact with the nozzle and the surface of the material to be straightened is scratched. There were restrictions, and no consideration was given to points such as clogging and reducing the suction effect.

作業を著しく阻害するという問題点がある。In both hot and cold straightening, the scale is released from the surface of the material to be straightened during straightening and adheres to the straightening roll or is deposited around the straightening roll. Therefore, in the conventional straightening machine, the scale is caught between the straightening roll and the material to be straightened and the reinforcing roll during straightening, scratches the surface of the material to be straightened, deteriorates the quality, and accelerates wear of the roll. There is a problem of doing. Further, since the scale on the lower surface of the material to be straightened is deposited inside the straightening machine, the maintainability of the straightening roll and the roll supporting portion is poor,
There is a problem that the work is significantly hindered.
