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: A method for operating a roll straightening machine having a number of forming tools, the forming tools including at least one set of upper and lower straightening rollers, a flat metal material to be straightened being conveyed between the upper and lower straightening rollers in a conveying direction. In order to achieve high straightening quality even as wear occurs, the method includes the following steps: a) determining the wear state of at least one of the forming tools; b) determining a correction value and/or a compensation value for the operation of the forming tool on the basis of the determined wear state of said forming tool; c) adapting an operating parameter, in particular an adjustment parameter or setting value, for the forming tool on the basis of the determined correction value and/or compensation value.

Abstract: The invention relates to a roller leveler (1) having a set of upper and lower flattening rollers (2), wherein each flattening roller (2) is provided with a rotary drive (3) actuated by leveler control (4) for rotating the flattening roller (2) to advance a to-be-flattened metallic flat material in a forward direction (F) and, thereby, flatten the flat, metallic material. To achieve an improved and optimal flattening result, the invention proposes that each flattening roller (2) has a first rotary drive (L1, L2 . . . Ln) for driving one axial end of the flattening roller (2), and a second rotary drive (R1, R2 . . . Rn) for driving one axial end of the flattening roller (2) and a second rotary drive (R1, R2 . . . Rn) for driving the other end of the flattening roller, wherein the leveler controller (4) is designed to apply a parameter determining the direction of rotation of the flattening roller (2) to the first and second rotary drives (L1, L2 . . . Ln, R1, R2 . . . Rn) individually based on a pre-set value. The invention also relates to a method of operating a roller leveler of this kind.

Abstract: A straightening machine having an allocated straightening roll drive including a top bearing frame and a bottom bearing frame, in which a plurality of straightening rolls and supporting rolls are held in a cassette-like manner and arranged in an interchangeable manner. An improved adaptability of a straightening machine to different straightening requirements and straightening areas is achieved in that all the straightening rolls and supporting roils respectively arranged in the top and/or bottom bearing frame are distributed into several straightening roll segments that are modularly adapted to one another and each configured in the form of an interchangeable cassette. Each straightening roll segment includes at least one layer of supporting rolls and at least one allocated straightening roll.

Abstract: A pressing tool part for eliminating a flatness defect on a flat semi-finished product provided with a pressing surface facing the flat semi-finished product. The pressing tool includes part half segments separated from each other by a material weakening, which are connected to one another on the one hand to by an elastically bendable bending bridge region of the pressing tool part, and on the other hand to a common actuator in order to elastically deform the pressing surface of the pressing tool part as a function of the flatness defect.
