Abstract (en)
[origin: WO2022109646A1] The invention relates to a method for producing a metal strip (2), in which the metal strip (2) is ground on at least one side (12, 13) over substantially its entire area, characterized in that, in a first step, a transverse curvature in the direction of the strip width (10) is created by straightening work on the metal strip (2), wherein a first side (12) of the metal strip (2) has a convex shape and a second side (13), opposite to the first side (12), of the metal strip (2) has an at least planar or concave shape, and in that, in a second step, by grinding the second side (13) of the metal strip (2), the profile of the strip thickness (11) D is changed in the direction of the strip width (10) to a uniform profile of a value of the strip thickness (11) D (D(x) = constant).
