Abstract
A method and apparatus for flatness measuring and measuring of residual stresses in a metallic flat product (): The method includes bending the flat product () in a bending device () such that a planar flat product () forms an arc () with a target bending radius rafter bending; measuring the contour and the actual bending radii r(y), in the region of the arc () of the bent flat product () at a plurality of positions along the width direction of the flat product (); and determining the flatness of the flat product () taking into account the measured contour of the bent flat product ().
