Abstract (en)

[origin: CA2666007A1] A method and apparatus for leveling a metal strip are disclosed, in particular a thin metal strip having a thickness .ltoreq. 1 mm, a tensile stress of at least 70% of the yield strength being generated in the metal strip between a braking roller set and a tension roller set, longitudinal curve being corrected by alternate bending between the braking roller set and the tension roller set in at least one leveling roller group having multiple leveling rollers, the diameter of the leveling rollers being so great that the strip follows the curvature of the leveling roller at the selected strip tension, and the diameter of the leveling rollers increasing from roller to roller within the leveling roller group.
