Abstract
Rolling mill for the pressure treatment of a web of material having two press gaps in each of which a different application pressure can be adjusted independently of the other gap. The two press gaps are formed between three rolls whose axes are situated parallel to one another and lie in two planes. The roll which adjoins the two other counter-rolls to form the press gaps is constructed as a pressure equalization roll with a stationary axial supporting member about which a shell is capable of rotating and in which hydrostatic supporting elements are arranged in rows extending parallel to the press gaps. The application pressure in the press gaps is produced exclusively by means of the hydrostatic supporting elements. The shell of the pressure roll shell is capable of moving in all radial directions relatively to the supporting member. The two counter-rolls are guided radially and axially.
