Patent ID: 8117877

Claim:
A method for manufacturing a product having a constant diameter or various diameters from a workpiece, in which the workpiece is clamped down in a clamping device, the workpiece and a first set of forming rollers are rotated about an axis of rotation relative to each other, wherein the rollers of the first set take up a first same axial position with respect to the work piece, wherein the workpiece is deformed by means of said forming rollers by placing the forming rollers into contact with the workpiece and moving the workpiece and/or the forming rollers in a direction along said axis of rotation, wherein at least a second set of forming rollers positioned at a second same axial position with respect to the work piece is placed into contact with the workpiece at a position behind the first set of forming rollers, the workpiece also being deformed by means of said second set of forming rollers and wherein two or more forming rollers, each being of a different set and taking up a different axial position with respect to the work piece, are mounted on a common holder and said holder is tiltable about a tilting axis toward and away to said axis of rotation wherein said tilting axis crosses said axis of rotation during the working of the workpiece into a selected shape.
