The smoothing device has a support beam. The beam is compensated along its line of flexure by a support member arranged centrally in it and which corrects the flexure of the support beam, which is due to the effect of gravity thereon or to a lesser extent due to any counter acting force of the doctor supported on the beam. A tube surrounds and is spaced radially out from the support member. A plurality of hydraulically or pneumatically actuated pressing elements are disposed between the tube and inside of the beam and extend over the length of the beam and are pressurized to support the beam.
