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.
