Abstract

The invention describes a method for roller levelling of strips with a maximum thickness of 4 mm by simultaneous stretching and bending by passing the strip (2) through a conventional roller levelling device with only two levelling rolls (1) but with a certain relation between the radiuses of the levelling rolls depending of the characteristics and thickness of the material in the strip (2).
