ABSTRACT:
Apparatus comprising a frame, a pair of generally parallel rolls each having trunnions at its ends journaled for rotation in bearings in the frame with a gap between the rolls, and means for driving the rolls. The rotation of each trunnion in its bearing tending to generate heat which tends to raise the temperature of the trunnions and frame above the ambient temperature. The apparatus includes a cooling system, having a coolant supply manifold and a coolant return manifold, each with a branch for each bearing, and a pump for circulating coolant through each bearing. The cooling system also includes a device for controlling the temperature of the coolant. A temperature sensor senses the frame temperature, and a control, responsive to the temperature sensor, controls the device for controlling the temperature of the coolant to maintain a predetermined temperature differential between the temperature of the frame and the temperature of the coolant, with the coolant temperature lower than the frame temperature, whereby the gap between the rolls is maintained substantially constant.
