<p>A self-loading controlled deflection roll (10) for forming a pressure nip (N) with another roll (4) has at least one support shoe (22, 24) mounted in a stationary support shaft (12) for controlling the deflection of the roll shell (14) in the direction of the nip (N). At either end of the controlled deflection roll, a pair of opposed guide shoes (38, 40, 42, 44) are slidably mounted on the stationary support shaft (12) to apply pressure against the roll shell (14) to stabilize the position of the roll shell relative to the stationary shaft. At least one guide shoe (40) on either end of the roll is equipped with a compensating piston to permit its face surface (57) to move radially outwardly relative to the guide shoe support on the stationary shaft. The guide shoes slidably reciprocate in planes parallel to the plane (15) of the nip through the longitudinal axis (16) of the roll and provide opposed, equal stabilization forces at substantially right angles to the plane of the nip. The guide shoes also have axially extending pads (64, 64') for bearing against annular end surfaces on the roll shell to maintain the roll shell fixed in the longitudinal direction relative to the support shaft during operation.</p> |
