Abstract (en)
[origin: CA3040160A1] The invention relates to a method and to a device for the stretch-bend leveling of a metal strip (B), wherein the metal strip (B) is alternately bent around stretching rollers (1-5) under a tensile stress and the degree of stretching is thus increased, wherein one or more stretching rollers (1-5) are provided with a non-metal coating. The method and the device are characterized in that one or more stretching rollers are provided with a coating (8) of plastic.
