Abstract
Profiles () are formed in a production line with a cross-section that varies along their length from a plane metal strip () that is unwound from a coil (), whereby edge cutters () and a number of roll-forming units (-) are used where not only the edge cutters but also the roll-forming units can be displaced individually sideways relative to the strip. The edge cutters () and the roll-forming units (-) are individually controlled such that they follow the lines of extent of the side edges () that are cut and the lines of the corners (-) that are subsequently formed, and the forming of one corner with a number of roll-forming units is started only after the forming of a corner that lies more closely to the edge of the strip has been completed. The formed profile is bent in a bending station integrated into the line, which bending station comprises rollers (-) that can be controlled to roll sections of the profile () to become thinner such that the profile is bent or twisted as it is formed.
