ABSTRACT:
The present invention is directed toward a controller for controlling local calender roll diameters by directing temperature controlled fluid against selected slices of a rotating calender roll. The calender roll has a diameter which responds to changes in temperature. Therefore, thermal expansion or contraction, resulting from localized heating or cooling of the calender roll by the temperature controlled fluid, corrects local non-uniformities in the spacing between cooperating calender rolls. The invention conserves energy by recirculating the temperature controlled air.
