METHOD FOR OPERATING A CALENDER ROLL SYSTEM, AND CALENDER ROLL SYSTEM

摘要

A calender roll system and method for operating the same. The calender rollsystem includes a roll stack having at least one center roll positionedbetween two endrolls, in which each of the at least one center roll and the two end rollshave a drivemechanism, and in which the rolls can be-loaded in a stacking direction. Themethodincludes loading the rolls to form at least one working nip with at least onecenter roll,and, in the at least one working gap, bending the at least one center roll outof theplane of the roll stack. Reaction forces required to bend the at least onecenter roll aregenerated by corresponding adjustment of drive moments of the at least onecenterroll.
