摘要： A ventilating roll (12) for introducing a supply of relatively dry air into the pocket spaces (P1, P3, P5) between dryer rolls (10) and the co-running fabrics (F) and paper web (W) in a papermaking machine, and removing the relatively moist air which is liberated from the traveling paper web (W) as it comes into contact with the heated dryer rolls (10). The ventilating roll (12) has a plurality of separate compartments (18, 20), some of which conduct super-atmospheric pressure air into the pocket spaces, and some of which conduct sub-atmospheric air out of the pocket spaces. The compartments (18) conducting air into the roll alternate with the compartments (20) for conducting air out of the roll. The temperature of the internal structure of the roll is thereby balanced circumferentially about the center shaft (16) of the roll (12) and thermal bowing of the roll is kept to a minimum.

摘要： 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.

摘要： A controlled deflection roll (10) has a unique liquid barrier and heat shield (72) which includes a chamber (82) filled with cooling fluid. In a preferred embodiment, the barrier comprises two chambers (82, 84) and a space (68) in fluid communication with both chambers (82, 84) for circulating cooling fluid between the chambers and into and out of the roll. The barrier (72) is interposed between the interior cavity (20) of the roll (10) containing the extremely hot hydraulic fluid which actuates the apparatus for controlling the deflection of the roll (10), and the bearings (54, 56) which rotatably align the roll shell (18) relative to the space (68). The barrier (72), thus, functions to thermally insulate the bearings (54, 56) from heat, whether by radiation or by direct contact with the hydraulic fluid.
