Abstract

A method uses a device to level a metal plate fabricated from high-strength metal material. The method includes providing a serpentine path between a plurality of upper and lower rollers in parallel arrangement to define a longitudinal spacing. The upper and lower rollers are positioned relative to one another such that a plunge depth is defined based upon a difference between a top-dead-center point of the lower rollers and a bottom-dead-center point of contiguous upper rollers, and a longitudinal spacing and the plunge depth are configured such that the upper rollers and the lower rollers are disposed to impart a bend radius on the metal plate as the metal plate is drawn through the serpentine path such that the metal plate bends about the outer peripheral surfaces of the upper and lower rollers. The bend radius is selected to achieve a desired plastification of the metal sheet.
