<p>A self-loading controlled deflection roll (6) has its tubular shell (52) rotatably supported on front and back bearings (42) which, in turn, are mounted on a bearing ring (12) which is outwardly-movable arcuately on a pair of opposed pistons (24, 26) and shoes (28, 30) at either end of the roll. The bearing ring (12) at each end of the roll is pivotally linked with the roll shaft (10) to prevent skewing movement between their longitudinal axes. The opposed pistons (24, 26) and shoes (28, 30) operating within the bearing rings (12) at the edges of the roll shell position and load the roll (6) into and out of nipping engagement with a mating roll (8) independently of the operation of a separate nip shoe (60) which controls the deflection of the roll. The pistons (24, 26) within the bearing rings can be used to either provide additional nip loading independent of the nip shoe (60), or provide a counterload in the opposite direction. Both can be used for edge correction.</p> |
