ABSTRACT:
A roll with an axially extending core having a central portion and two end portions. A shell member that has a central portion and two distal end portions surrounds the core and is attached to the core at their respective central portions such that the distal end portions of the shell member are unsupported to enable them to deflect in relation to the adjacent end portions of the core. The core has a duct therein that communicates with at least one substantially annular passageway provided in the shell member for permitting a temperature controlling fluid medium to flow to the passageway from a source that is attached to the duct.
