A method for manufacturing a substantially rotationally symmetric rim bed having a wall thickness varying along the longitudinal axis by means of cold forming, wherein the side walls of a substantially cylindrical metal bed having a substantially constant wall thickness are flared radially outwards in a pressing operation, and wherein the wall thickness of the flared side walls is varied along the longitudinal axis by means of flow-spinning, with axial stretching and profiling of the sides. The invention further relates to an apparatus for manufacturing a rim bed by means of cold forming. |
