Patent ID: 7536891

Claim:
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 generally vertical 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.
