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.

A method comprising:
- providing first and second rollers having first and second recessed profiles, respectively, having first and second volumes, respectively, the first profile being deeper and narrower than the second profile and the first and second volumes being the same;
- applying the first profile and subsequently the second profile to a metal strip to form a contour on the metal strip;
- and
- producing a structural element from the metal strip having the contour.
A method comprising:
- providing first and second rollers having first and second recessed profiles, respectively, having first and second volumes, respectively, the first profile being deeper and narrower than the second profile and the first and second volumes being the same;
- applying the first profile to a metal strip to form a partial contour on the metal strip;
- applying the second profile to the partial contour to form a final contour;
- and
- producing a structural element from the metal strip having the final contour.
A method comprising:
- providing first, second, and third rollers having first, second, and third recessed profiles, respectively, having first, second, and third volumes, respectively, the first profile being deeper and narrower than the second profile, the second profile being deeper and narrower than the third profile, and the first and second volumes being the same;
- applying the first profile to a metal strip to form a first partial contour on the metal strip;
- applying the second profile to the first partial contour to form a second partial contour;
- applying the third profile to the second partial contour to form the final contour;
- and
- producing a structural element from the metal strip having the final contour.
