Abstract
In order to control and optimize, without stopping production, bowing in the outer wall of a calender roll in which bowing is produced by the action of pressure on an incompressible liquid enclosed in the roll, the invention proposes that, based on error signals generated from continuous thickness measurements and from at least one other quality characteristic, the temperature of the liquid is controlled and the nip modified to correct for deviations from the correct thickness.
