Abstract: The present application describes a system to compensate deformations in press bending machines, in particular press bending machines used for plate conformation or bending, which comprises a group of uprights (1) for supporting the upper apron (7) of the press bending machine, wherein each upright (1) comprises two beams (2,3) placed on the upper and lower ends of a pillar (4) being coupled thereof by means of fastening means (5) and a compensation actuator (6) placed between the beams (2,3) and coupled to the beam (3) at one end thereof. The presented technology allows to increase the distance between the aprons of the press bending machine and the upright scye (1) so that said press bending machine allow the plate deformation in various shapes and dimensions.
