Abstract
The present disclosure relates to a method for producing a structural element. A number of upper and/or lower rollers arranged one after the other in a direction of rolling is rolled in a metal strip to produce a varying thickness in the metal strip. The method includes providing the upper and/or lower rollers of each group with shape-changing profiles in the direction of rolling. The shape-changing profile of each group in each case exhibits a constant volume. The method may further include prefabricating the metal strip with partial contours produced on the basis of the shape-changing profiles to a desired final contour. The method may also include feeding the prefabricated metal strip with the desired final contour for further processing steps.
