ABSTRACT:
The compression roller in a paper producing machine has a relatively thin outer casing which rotates and is supported directly below the point of contact by a stationary support system. The support system includes an elongated cylinder and piston assembly. Attached to the piston is a pivotable support bar whose surface conforms substantially to the inside surface of the rotating casing. A pump supplies pressurized fluid medium through conduits in the piston to a long channel in the support bar, thus providing a fluid film on which the casing is supported. Side pockets in the support bar are connected to the long channel and serve to stabilize and centralize the position of the support bar.
