Abstract
The invention relates to a method and a device for continuously stretch-bend-leveling metal strips, wherein a strip under a tensile stress below the elastic limit is alternatingly bent about at least four straightening rollers in the plastic or elastic-plastic region and thereby undergoes plastic stretching. The bending radii of all four straightening rollers are thereby set dually and independently of each other, as the straightening rollers are set up having individually controlled positions.
