Abstract
A method for producing a profile from a sheet-metal strip is disclosed. The sheet-metal strip is bent at least twice during a first stage, where, as viewed in the cross-section of the sheet-metal strip, a center section as well as two flank sections are formed, which project angularly from two opposing end regions of the center section. During a second stage following the first stage, the center section is compressed by two complementary roller arrangements which engage on the two opposing end regions of the center section, and the sheet-metal strip is thereby locally thickened.

A method for producing a profile from a sheet-metal strip, comprising the steps of:
- bending the sheet-metal strip at least twice during a first stage such that, as viewed in a cross-section of the sheet-metal strip, a center section and two flank sections are formed, wherein the two flank sections respectively project angularly from two opposing end regions of the center section and define a length therebetween, wherein the two opposing end regions define a plane of the center section that runs along the length of the center section;
- and
- during a second stage following the first stage, thickening the center section of the sheet-metal strip by compressing the center section parallel to the plane of the center section by two complementary roller arrangements which engage on the two opposing end regions of the center section.
