Disclosed is a device for bending open, half-open, and closed hollow profiled members ( 11 '). Said bending device operates with a central roller ( 3 ) that rests against the inner surface of the bent profiled member, a milling roller ( 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 the 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 rollers and milling rollers ( 3, 4 ).
