Abstract
A system and method for removing flatness faults from a metal flat product, in particular a metal sheet or a strip, having multiple straightening rollers arranged on opposite sides of the flat product. In order to simplify and to enable more cost-efficient removal of flatness faults from a metal flat product, at least two cooperating straightening rollers arranged on opposite sides of the flat product each have at least three individually-adjustable partial rollers arranged axially adjacent to one another.
