The compensating elements can be moved here to an over-compensating position prior to the deforming operation and pressed out of their over-compensating position during the operation by the load on the beam, wherein each compensating element exerts an adjustable resistance force on surrounding parts of the press. It is conversely possible for the compensating elements each to be pressed stepwise to a position compensating the detected deviations during the deforming operation. It is possible to use (piezoelectric) actuators to exert the resistance force and/or to move the compensating elements. The invention further relates to a device with which this compensation method can be performed. ## Claims ### Claim 1 Method for compensating deviations in a deforming operation between two beams of a
