Abstract (en)
[origin: EP0972878A2] In the calender assembly, for processing a paper web, the intermediate roller (5,10) next to the upper adjustable bend roller (4,9) in each roller stack is in a fixed position at the frame. The upper adjustable bend rollers (4,9) give a variable pressure in the top nips (25,26), independently of the pressures applied on the web in the following nips (28-33). Both end rollers (4,8,9,13) are lifting mantle types, on fixed carriers. The intermediate rollers (6,7,11,12) below the upper intermediate rollers (5,10) are mounted on levers (27), which pivot on axes mounted to the frame. Two identical stacks of rollers (2,3) are in succession in the direction of web (24) travel. The top intermediate roller (5) of the first roller stack (2) acts on one side of the web (24), and the top intermediate roller (10) of the second roller stack (3) acts on the other side of the web (24).
