The cantilever rollers have axes of rotation that are offset relative to one another in the direction of travel of the profiled panel through the machine and having a roller profile also generally corresponding to the profiled panel. At least one sweep roller is positioned downstream of the cantilever rollers for bending said panel in a longitudinal direction as said panel passes past said sweep roller. The sweep roller also has a roller profile generally corresponding to the profiled panel. The at least one sweep roller can be positioned to the degree of bend of the smooth curve formed in said profiled panel by the machine.
