PURPOSE:To straighten effectively a malformation of strip by a simple construction by making the work-roll unit of a tension leveler movable in the longitudinal direction in the plane of strip and changing a bending curvature in the sheet width directon. CONSTITUTION:A bending curvature is gradually changed in the sheet width direction of a strip by contruction a device so that the work rolls 1 of a stretching-roll part of tension leveler and the work rolls 2 of a straightening, small-diametral roll part are movable in the longitudinal direction (a) in the plane of the strip S. In this way, the bending moment of tensile and bending deformation is changed in the sheet width direction, to absorb an nonuniform partial strain and a camber, etc. in the sheet width direction. Thus the malformation of a metallic strip is effectively straightened by a simple construction. |
