Abstract: A cold roll forming apparatus for forming a variable profile. The apparatus comprises a forming unit having a least one adjustment stand which includes a roll stand with a pair of rollers between which the sheet metal strip is passed through along its longitudinal direction (X), wherein the roll stand is translationally and rotationally displaceable during the cold roll forming with at least one translatory degree of freedom and one rotary degree of freedom being independent from each other.

Abstract: A flexible retaining device (1) for a profiling installation for clamping a sheet metal (5) to be profiled is provided. Furthermore, a method for profiling a sheet metal (5) by using the flexible retaining device (1) is provided as well as sheet metal profiled with the method.

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.

Abstract: The invention relates to an apparatus for producing a profile by means of cold roll forming, said apparatus comprising a forming unit (9) having a least one adjustment stand (17, 17?, 17?, 17??) which comprises a roll stand including a pair of rolls between which there is a gap through which the sheet metal strip is passed along the length direction (X), wherein, during the cold roll forming, the roll stand is translationally and rotationally displaced with at least one translational degree of freedom and one rotational degree of freedom. According to the invention, the apparatus for forming a profile with varying height is configured so that the roll stand has one degree of freedom for rotation about an axis of rotation extending substantially in the direction of the gap between the rolls, said rotational degree of freedom being independent of the at least one translational degree of freedom. The invention also relates to a corresponding process.
