ABSTRACT:
In a leveling line, the shape of a rolled material is corrected by applying a longitudinal tensile force to the material on the entrance or the exit side or both the sides of a roller leveler or within it, a warp of the material is corrected by applying a bending tension to the material within the roller leveler, and a camber of the material is corrected by applying a larger plastic elongation to either one of the widthwise edges of the material than to the other, on the entrance or the exit side or both the sides of the roller leveler or within it.
