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.

Abstract: The invention relates to a device and a method for straightening pressing a flat metal product, as well as a roll stand (300) comprising said device (100). Known straightening presses typically comprise an upper press frame having a pressing die and a lower press frame having a table for supporting the flat product to be straightened, wherein the upper press frame is arranged opposite the lower press frame and both press frames can be moved vertically with respect to one another. The problem addressed by the invention is that of providing a device (100) for straightening pressing a flat metal product, a roll stand (300) comprising said device (100) and a method for operating a roll stand (300) of this type, which enable economically efficient straightening of flat products. This problem is solved in relation to the device (100) through the subject matter of claim 1. The subject matter is characterized in that the upper press frame (110) comprises carrier elements (114) in the region of both narrow sides thereof as gripping points for a balance device for the upper work roll in a roll stand; and in that the lower press frame (120) comprises support elements (124) in the region of both narrow sides thereof for support on the stands of the roll stand.

Abstract: A horizontal roll stand includes upper and lower back-up rolls, removable work rolls, a balancing device for supporting the upper work roll, and a vertical adjustment device for the lower back-up roll. The work rolls are removed and a press device for straightening pressing of a flat metal product is inserted into the roll stand. The press device includes opposing upper and lower press frames that are displaceable relative to each other. The upper press frame and the lower press frame have one of a selectively moveable pressing die or opposing selectively moveable table with a trough for immersion of the pressing die to selectively press and flatten defects in the flat metal product. The upper press frame includes carrier elements which contact a balancing device of and for support within the roll stand. The lower press frame has support elements for being supported on stanchions of the roll stand.
