ABSTRACT:
A press roll having a shaft, a cylindrical shell and axially arranged support devices mounted on the shaft to exert radial forces on the shell in opposition to pressing forces to prevent shell distortion. Ducts in the shaft convey fluid under pressure to the support devices each of which includes an annular chamber defined by annular radially extending walls with peripheral axial flanges, an annular compressible and flexible ring and seals to keep the fluid from leaving the chamber. Various embodiments of the annular rings and seals are disclosed. Pivot bearings prestress the system and support the shell on the shaft for relative eccentric rotation.
