fixed cross beam and a rotating hollow roller semicylindrical longitudinal chambers are separated and divided off by longitudinal seals and end cross seals in the space between the crosshead and the hollow roller at least the longitudinal chamber on the roller nip side can be filled with a compressed gas the longitudinal seals and the end cross seals are doubled and are made of closely juxtaposed pairs of sealing strips or into the spaces between the sealing strips can be introduced a sealing liquid which seals the longitudinal chambers sealing liquid which has penetrated into the longitudinal chambers is continuously removed application_number US 62457196 A description the roller 100 includes a fixed cross beam 1 around which a hollow roller 2 rotates the cross beam 1 leaves a space 4 towards the inside circumference 3 of the hollow roller 2 so that the cross beam can bend within the hollow roller 2 when a stress occurs in the roller nip w without touching inside circumferences the forces caused by the line pressure in the roller nip w are transferred by the hollow roller 2 via a compressed gas in space 4 to the cross beam 1 which deflects under the effect of these forces and in this way generates the counter forces which bring about equilibrium in the exemplary embodiment shown in fig1 the counter roller 15 and the roller nip w are located on the top so that the cross beam 1 will deflect downwards for this reason the cross beam 1 is slightly flattened on its bottom 1 39 in order to create room for this deflection as can be seen in fig1 the compressed gas is located in a semicylindrical.
