Abstract

The invention relates to a press brake, press break beam, press brake table, and an edging method. The press brake (1) comprises a body (2), lower beam (4), upper beam (3) and powered members (6a, 6b) for moving the upper beam relative to the lower beam during edge pressing. The press brake comprises several adjusting units (11) for bend compensation of support surfaces (9) on the beams. The adjusting units are each separately controllable and comprise an eccentric mechanism (12). The adjusting units may bend the support surface or act on the support of the support surface. The adjusting units may reside on the beam, table (17), or between the beam and table.
