Abstract: Temperature control means for a deflectable shell roll having lengthwise passages and being mounted for rotation on a fixed beam received in the inner race of a triple race bearing. The middle race of the bearing rotates with the shell roll and provides conduits between the roll shell passages and a central axial bore communicating with a rotary joint providing an inlet and an outlet for circulation of temperature control fluid through the shell passages.
