Abstract
A method and apparatus for leveling of metal sheets conveyed through leveling gaps formed by several adjustable upper and lower leveling rollers and adjusted as a function of the sheet cross-section and the nominal sheet strength is disclosed. After initial maximum deformation, the sheets are subsequently repeatedly bent in alternate directions with a greatly diminishing degree of deformation resulting in an improved operational mode if the leveling range of a leveling machine is expanded toward the thicker metal sheets by a smaller quantity of leveling rollers in engagement, and thus a larger roller pitch, in case of sheet thicknesses exceeding the nominal sheet thickness of the leveling range.
