Roll-forming or bending machine

Roll-forming or bending machine (1) for forming at least one angled or rounded and simultaneously tapered hollow body or workpiece from a material blank, the roll-forming or bending machine (1) comprising at least one tapered roll (2) and at least one counter element, between which a forming pressure is applied to the material blank and of which at least the at least one counter element has an elastic surface, the at least one counter element comprises a bending table (3) for supporting the material blank, the at least one roll (2) is adapted to apply a deforming pressure to the material blank arranged on the bending table (3), the bending table (3) is guidably supported for movement in a longitudinal direction and can also rotate about a rotational axis (5) and the at least one roll (2) can move perpendicular to the longitudinal direction, such that a change in a relative position of the at least one roll (2) and the rotational axis (5) of the bending table (3) caused by a rotational movement of the bending table (3) can be compensated, and wherein fixing pins or similar fixing elements, which attach with end regions thereof projecting past the bending table (3) to outer contours of the material blank and which can be lowered in the bending table (3) against a restoring force, are provided for fixing or setting the material blank.
