ABSTRACT:
An extended nip press apparatus is disclosed for pressing water from a formed web. The apparatus includes a frame and an elongate shoe pivotally supported by the frame. A backing roll cooperates with the shoe for defining therebetween an extended nip for the passage therethrough of the web. The backing roll includes a beam which extends in a cross-machine direction, the beam being rigidly supported by the frame. A roll shell is rotatably supported by the beam, the roll shell cooperating with the shoe for defining the extended nip. A plurality of roll shell deflection compensating devices are disposed in a cross-machine direction between the roll shell and the beam for urging the roll shell towards the elongate shoe and for compensating for deflection of the roll shell relative to the shoe during passage of the web through the extended nip.
