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

A doctor for creping tissue from a surface of a Yankee dryer is provided. The doctor includes a frame and a support which extends from the frame. A swing arm is pivotally secured to the support about a pivotal bearing. The swing arm defines a further bearing. A pivot extends through the further bearing for rotatable movement relative to the swing arm such that the pivot is rotatably supported by the swing arm. A doctor is rigidly secured to the pivot for doctoring the tissue from the surface of the dryer. A blade is removably secured to the doctor, the blade defining an operative edge which cooperates with the surface of the Yankee dryer for creping the tissue from the surface of the dryer. A loader is operatively connected to the pivot for rotating the pivot within the further bearing for loading the operative edge against the surface of the dryer. A blade angle changer is operatively connected to the swing arm for pivoting the swing arm relative to the support, the arrangement being such that movement of the angle changer selectively changes an angle defined between the blade and the surface of the dryer.

A non-self loading controlled deflection roll for a papermaking machine having a machine direction and a cross-machine direction, the roll including a shaft support member, first and second shell support members, a roll shaft having a longitudinal axis in the cross-machine direction, the shaft having axially spaced first and second ends, a roll shell surrounding the shaft, the shell having axially spaced first and second ends, the shell being rotatable about the shaft, a bearing pad supporting the shell relative to the shaft, the bearing pad being located between the first and second ends of the shell, first and second outboard bearings supporting the shaft relative to the shaft support member adjacent the first and second ends, respectively, first and second spherical bushings supporting the shell relative to the shaft, the first and second spherical bushings being mounted on the shaft axially inwardly of the first and second outboard bearings, respectively, each of the spherical bushings having a first annular bushing member supporting the respective first and second shell support members and a second annular bushing member mounted on the shaft, the first and second annular bushing members having complementary spherical engagement surfaces, and first and second outboard shoe assemblies.

A hydraulic crown support system employs a stationary cross head mounted within a cylinder or beneath an extended nip shoe. Individual hydraulic pistons are disposed along the stationary cross head, which, under the force of hydraulic pressure, support the inner wall of a roll or an extended nip shoe. The displacement of the support cylinders is controlled through one or more adjustable ports formed in the sidewall of the hydraulic cylinder or cylinders which support the roll or extended nip shoe. With a piston which extends from one end of the stationary cross head to the other, some tilting from one side to the other of the cross head can be achieved by the adjustment of the pressure ports, thus compensating for misalignment in the vertical direction between an extended nip or crown-controlled roll.

A device for use in conjunction with a slice lip adjusting mechanism for controlling the distribution of stock across the web of a paper machine to obtain a desired cross-machine profile of basis weight, moisture, caliper and the like. The device is used in conjunction with a slice body and a slice lip which abuts the body but is at least slightly movable relative thereto. An apertured adjusting arm engages the slice lip for fine adjustment of the lip position. Disengagement between the adjusting arm and the slice lip is prevented by a headed bolt which passes through the aperture in the adjusting arm and is received in threaded engagement in the slice body, in combination with a plug which is received in threaded engagement at the head of the bolt and a compressed spring which acts between the plug and the adjusting arm. A tube is provided with an internally threaded portion receiving the plug in threaded engagement at one end, with the opposite end of the tube being spaced from the adjusting arm by a small predetermined clearance thereby limiting the extent to which the adjusting arm can move away from engagement with the slice lip. Locking means are provided to lock the tube in an adjustable position relative to the plug.

An extended nip press for removing water from a traveling web in a paper machine including a press roll wth an elongate shoe having a concave surface facing the roll and forming an extended nip therebetween with an endless belt trained over the shoe for passing through the nip and first and second belts passing through the nip with the belt supported by a plurality of guide rolls or by an annular shell having continuous smooth outer surface extending from the outgoing side of the nip back to the oncoming side of the nip with a beam within the shell and a uniform fluid support for the shoe supported on the beam.

A vacuum guide roll apparatus is disclosed for guiding a web between an upstream dryer and a downstream dryer of a dryer section. The apparatus includes a perforate roll shell having a first and a second end. The shell defines an elongate chamber which extends between the first and the second ends. A first and second shaft are rigidly secured to and disposed coaxially relative to the shell. The shafts are disposed adjacent to the first and second ends respectively of the shell. The shafts define respectively a first and second journal. A first and second bearing cooperate with the first and second journals respectively for rotatably supporting the roll shell. A housing is disposed coaxially relative to the shell and adjacent to one of the shafts. The housing defines a passageway which is connected to a source of partial vacuum. A first annular seal is disposed between the housing and the one shaft for sealing the housing relative to the one shaft.

An extended nip press has a looped belt mounted over a shoe having a concave surface which presses the belt against a mating surface on a roll to provide an extended nip. The shoe has a support which is movable in a skewing sense relative to the longitudinal axis of the roll. Lateral movement of the belt is monitored. When it has moved beyond predetermined limits in either direction, the shoe is skewed to alter the frictional forces on the belt as it passes over the shoe's surface. This controls the position of the belt and keeps it centered in the nip.
