Abstract (en)
[origin: EP1209286A2] A calender has a bunched array of rollers with two end-rollers and a number of intermediate rollers. In operation two neighbouring rollers, each of which sags slightly, form a nip. The sag of adjacent rollers (i, i + 1) differs. especially the second roller facing the concave surface of the first roller, has less sag than the first. Also claimed is a process to treat a material web passing through several nips where it is subjected to pressure and each nip is formed by a first and second roller. The sag in each roller has a bending amplitude on the convex side of the first roller which is essentially identical to the bending amplitude on the concave side of the second roller. Each roller has a set of support bearings left and right. The distance MbML between the bearings on one roller is 0.1 to 2 per cent different to the distance MbML in the second roller bearing, with reference to the longer of the two dimensions. At least one of the intermediate bearings has a variable bearing distance MbML.
