Abstract (en)
[origin: DE19521402C1] A calender set for the treatment of paper web has at least one roller stack which has, for top and bottom rollers, flexion compensation rollers each with a casing supported by hydrostatic elements mounted on an internal stationary carriage and, for intermediate rollers, both hard and elastic rollers. The rollers form at least four working gaps, which are bounded by one hard and one elastic roller, and if necessary a changeover gap bounded by two elastic rollers. The top (2) and bottom (3) roller casings (15, 15a) carry a cover (27a) of flexible elastic plastic or are themselves of elastic plastic with a deformation factor defined by: F = {(1.4 x 10<5>)/E} x (100/S)<2.65> \- 4 where E is the modulus of elasticity for the roller cover in N/mm<2> and S is the wall thickness in mm. The neighbouring intermediate rollers (4, 13) are hard rollers.
