ABSTRACT:
A metal plate bending machine is disclosed having a flap supported by a trolley displaceable in a cradle defining a supporting and guiding track which is in the shape of a concave cylindrical envelope portion, whose concave envelope portion is open in the direction of clamp elements, and with the track supported by a chassis suspended from the frame by a vertical and horizontal position adjustment mechanism. The flap has a radial symmetry with a plane radially passing through the flap and the center of the envelope portion and with the folding head presenting a symmetric profile on either side of the plane.
