ABSTRACT:
A device for selectively controlling the diameter of sections of a calender roll. The device comprises a plurality of nozzles which direct jets of superheated steam against sections of the calender roll. Thermal expansion, resulting from localized heating by the steam jets, corrects local non-uniformities in the gap between adjacent cooperating calender rolls. Moisture which condenses from the steam onto the calender roll surface is removed by a flow of air past the roll surface.
