Abstract
The invention relates to a method for manufacturing tubes and profiles with variable wall thickness over the length. The method comprises the steps of flexible rolling of continuous material strip with variable thickness in the longitudinal direction of the strip material to a final wall thickness which is continuously reduced with respect to the original wall thickness, reshaping the material strip to form a continuous tube or profile and cutting to length individual tube or profile pieces from the continuous tube or profile.
