Method, apparatus and computer program product for setting the bending of at least one straightening roller of a roller straightening machine

An apparatus for adjusting the bending of at least one straightening roller (7) of a roller straightening machine,

• wherein the straightening rollers (7) are supported by means of a plurality of supporting roller devices (4) arranged beside one another in the axial direction (A),
• wherein each supporting roller device (4) can be adjusted by means of an actuating device (13) such that stresses are produced in the straightening roller (7),
• wherein, to control the actuating device (13), a control system is provided, by means of which the adjustment of the supporting roller device (4) can be set manually,
• wherein limiting values (vMA, vMI) with respect to the stresses produced in the straightening roller (7) are stored in the control system, and
• wherein the control system is designed such that, in the event of a manual change in the adjustment of one of the supporting roller devices (4), maxima (MA) and minima (MI) of the stresses produced in the straightening roller (7) are calculated, it is checked whether the maxima (MA) and minima (MI) lie within the limiting values (vMA, vMI), and a further adjustment of at least one of the further supporting roller devices (4) is changed automatically by means of the control system in accordance with a predefined algorithm, such that the stresses produced in the straightening roller (7) remain within the limiting values (vMA, vMI).
