Abstract

A controlled deflection roll system includes a rotative cylindrical shell having an outside adapted to form a nip with a counter roll, a non-rotative shaft extending axially through and radially spaced from the shell's inside and having projecting ends to which force is applied to press the shell against the counter roll. Inside the shell pressure elements press the shell in the same direction, the counter roll providing a reaction, and because the shell does not have its ends journaled on the shaft, the shaft can float inside the shell in dependence on the forces involved. Automatic devices automatically responsive to any radial displacement of the shaft relative to the shell control the force applied to the shaft's ends so as to keep the shaft centered at its ends within the shell, permitting the application of a rotary drive to the shell.
