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.

Abstract: A spreader bar apparatus is disclosed for separating slit portions of a web. The apparatus includes a first spreader bar which extends in a cross-machine direction relative to the web. The first spreader bar is bowed relative to the slit portions such that the slit portions are separated axially relative to each other when the slit portions are guided around the first spreader bar. A second spreader bar is disposed downstream relative to the first bar and extends in a cross-machine direction relative to the web for guiding the separated slit portions. The second bar is bowed relative to the separated slit portions such that each of the slit portions disposed downstream relative to the second bar is disposed parallel to each other.

Abstract: An air classifier system which embodies two rotary drum classifiers, each with an individual adjustable plenum, the drums being individually angled at selected inclinations and the plenum capacities being variable, so that two separate masses of commingled materials such as municipal refuse and oversize bulky waste, for example, may be simultaneously classified and will produce a combined single output of refuse derived fuel.
