Abstract: A method which influences the thickness and gloss and/or smoothness in the treatment of fiber material webs in at least one press gap formed by rolls, wherein at least one adjustable deflection roll is used and a plurality of correction sections is provided over the press gap length which can be differently influenced with respect to temperature and/or pressure, and wherein, for the decoupling of the two correction procedures possible pressing force changes in the correction sections of the press gap resulting from local changes in diameter of the relevant roll caused by changes of the surface temperature are at least substantially prevented with the support elements and jacket.
