Abstract

CONTROLLED DEFLECTION ROLL A controlled deflection roll comprising an inner shaft and an outer roll shell which is attached to the shaft at its middle where the deflection of the roll shell can be eliminated by supporting forces generated by hydraulic pressure applied on balls disposed in radial borings in pressure means located at the ends of the roll shell.
