A roll-forming or bending machine ( 1 ) is provided for forming an angled or rounded and simultaneously tapered hollow body or similar workpiece from a material blank. The roll-forming or bending machine ( 1 ) has at least one tapered roll ( 2 ) and at least one counter element, between which a forming pressure can be applied to the material blank. The one counter element has an elastic surface and is constructed as a bending table ( 3 ) for supporting the material blanks, so that the one or more rolls ( 2 ) apply the forming pressure on the material blank on the bending table ( 3 ). The bending table ( 3 ) is guided so that it can move in the longitudinal direction and can rotate about a rotational axis ( 5 ), and the one or more rolls can move perpendicular to the longitudinal direction, allowing a change in the relative position of the roll ( 2 ) and rotational axis ( 5 ) of the bending table ( 3 ) caused by a rotational movement of the bending table ( 3 ) to be compensated. Because the roll-forming or bending machine can eliminate the need for a roll with separately supported roll sections and because the roll necessary for forming the material blank can have a relatively small roll minimum diameter, rounded and simultaneously tapered workpieces can also be shaped or bent with a relatively small radius.
