Beschreibung
Zusammenfassung:	A description is given of a process for adjusting the thickness and gloss and/or smoothness in the treatment of fibrous webs in at least one press nip formed by rolls, at least one adjustable bending roll being used and a multiplicity of correction sections being produced over the length of the press nip, which can be adjusted in a different way with respect to temperature and/or pressure, the impending pressing force changes in the correction sections of the relevant press nip, caused by changes of the local diameter resulting from surface temperature changes of the relevant roll, being at least considerably prevented by means of sufficient supporting element and cover flexibility, for decoupling both correction processes.
