CALENDER
A calender comprises at least two adjacent rolls (26, 27) whic form a nip (WS) through which a web passes. At least one roll is designed as a hollow roll with a roll sleeve (26a; 27a), and a pressing plane is defined by the centreline of the adjacent rolls. At least one roll is such that at least one direction of the pressing plane is fixed in the two front regions. Both rolls are pressed against each other over the length of the nip by hydrodynamically actuated force elements (26c; 27c). The force elements are connected, in facing supporting regions, to a common control element (32) via their hydraulic lines (26d; 27d), in which there are no control elements.
