Abstract
A floating roll with longitudinal chambers formed in a space between a hollow shell and a cross piece, of which one chamber is the pressure-effective longitudinal chamber, on which the hollow roll is braced via a pressure liquid, has strip-shaped longitudinal seals provided in duplicate and disposed symmetrically relative to the meridian plane separating the longitudinal chambers so that each of the longitudinal chambers can be sealed against the higher liquid pressure and the cross piece need not be turned around for a change in the direction of action.
