1. A device for compensating deviations in a deforming operation between two beams of a press, the device comprising:
at least one compensating element arranged at a chosen location in the press,
a detector for detecting the deviations during the deforming operation,
an electromechanical mover adapted to move the at least one compensating element relative to the beams while under load during the deforming operation in a controlled manner, and
a controller connected to the detector and adapted to control the mover so as to move the compensating element during the deforming operation;
wherein in a non-loaded state the at least one compensating element is movable by the mover in a first direction towards the opposed beam of the press and beyond an optimal compensating position to an over-compensating position; and
wherein while under load the at least one compensating element yields in a controlled manner through exertion of sliding resistance forces on surrounding components of the press, said resistance being provided by a plurality of sloped contact surfaces, including slopes β and γ, respectively of the compensating element and the mover, and further those of an adjacent support element, thus the compensating element is movable by a load on the beam in a second direction to be pressed out of its over-compensating position, and the mover is adapted to exert an adjustable resistance force on the sloping contact surfaces and surrounding parts of the press.
