Abstract
The invention relates to a method for roll-bending a profile which comprises at least one cross-sectional region which is formed from a plastics material which is shaped by extrusion. A first and a second bending roller set are provided, each including bending rollers which are arranged in such a way that a passage, which enables guiding of the profile, is formed between the bending rollers of each of the bending roller sets. The profile is bent about a first bending axis and about a second bending axis which is non-parallel thereto, the translations and rotations of the second bending roller set being brought about simultaneously at least at times and/or mutually offset in time in a predetermined sequence.
