Abstract: The present invention relates to a method for producing a profiled metal sheet, comprising the following steps in the indicated order: a) roll forming at least part of a sheet metal strip by means of a roll forming unit, wherein the sheet metal strip determines a first working plane of the roll forming unit, in respect to which parts of the sheet metal strip are bent up to form the profiled metal sheet, and wherein the bent parts of the sheet metal strip are curved at least partially in respect to the first working plane; and b) bending the profiled metal sheet by means of a bending unit, wherein the bent up parts of the profiled metal sheet are bent such that a second working plane is formed, wherein the first working plane becomes curved. The present invention thus provides an easy-to-implement, resource-conserving and cost-effective method.

Abstract: The invention relates to a system for cold roll forming profiles having variable cross-sections, with several roll stands arranged in a row, each containing a pair of rollers, between which a sheet-metal strip (2) is guided along its length (X), wherein the roll stands are moved translationally transversely to the length of the sheet-metal strip and rotationally about an axis of the roll stand during cold roll forming. According to the invention, a re-forming device (8, 10, 12) is arranged behind at least one of the roll stands and has at least one drive for generating a movement of the re-forming device in a plane transversely to the length (X) of the sheet-metal strip.
