摘要

Production of a thick profiled one-piece rolling stock comprises deforming the starting material widthwise using rollers which penetrate into the starting material forming a three-dimensional profile in the longitudinal as well as in the spreading direction by defined overlapping of the deformation regions. An Independent claim is also included for a rolling device for carrying out the process. Preferred Features: The process is carried out in one step and the rollers travel in the height and/or in the width direction during rolling. The number of rollers in contact before and/or during the process is varied.
