An apparatus for bending metal sheet comprises a frame (1), a stationary lower beam (2) with a lower clamp (5) and a movable upper beam (3) with an upper clamp (6). The clamps each have a clamping face for clamping a metal sheet in a working position. The apparatus further comprises a lower bending beam (13) and/or an upper bending beam (14) for bending upwardly or downwardly, respectively, a clamped metal sheet. At both sides the bending beam(s) is/are supported in the frame rotatably around an axis and independent of the upper and/or lower beam. The body of the lower or upper bending beam (13, 14) in a working starting position extends substantially perpendicular to the clamping face and the lower and upper clamps (5, 6) determine in cross-section in the working position a V-shape, the apex of which is directed towards the axis (15, 16) of the bending beam being in the working position. <IMAGE> |
