Disclosed is a device for bending open, half-open, and closed hollow profile d members (11'). Said bending device operates with a central roller (3) that rests against the inner surface of the bent profiled member, a milling rolle r (4) which leans on the outer surface of the bend, and a bending roller (11) located at the discharge end of the profiled member. Said bending roller (11 ) acts upon the outer surface of the bend, counter to the supporting effect of a support roller (5, 6) that rests against the outer surface of the bend at th e feeding end. In order to allow also thin-walled, sensitive profiled members to be shaped, additional milling rollers (12, 13) that act upon the top and bottom sidewall of the profiled member are disposed on a plane extending perpendicular to the bending plane in relation to the opposite central rolle rs and milling rollers (3, 4).
