ABSTRACT:
A curved roll with a longitudinally-curved axle which supports roll sections or spools by way of roller bearings seated on the axle has a flexible torque coupling between adjacent spools. Each coupling flexes to accommodate the curvature of the roll and both seals lubricant within the roll from leakage and seals dirt and other external contaminants from the roll interior. Each coupling employs a tubular coupling element which mechanically seats at each axial end within a circumferential channel internally recessing the spool end. Axially-extending members on each spool engage the coupling element for ensuring positive torque tranfer between the adjacent spools.
