Abstract

The body of the lower or upper bending beam (13,14) in a working starting position extends perpendicular to the clamping face and in that the lower and upper clamps (5,6) determine in cross-section in the working position a V-shape. The apex is directed towards the axis (15,16) of the bending beam being in the working position. The height of the clamps (5,6) is at least three times and preferably at least five times the thickness of the clamps. Upper and lower beams (2,3) which have a triangular cross-section, wherein the front triangular side is substantially aligned with the corresponding clamp (5,6).
