Abstract

Controlled deflection roller, comprising a rotationally supported inner shaft and outer roller frame attached to the shaft at its center or close to it, where the deflection of the roller frame caused by the load acting on the roller can be eliminated, by forces of support acting on the ends of the roller frame and which are generated by pressure means, characterized in that the support forces are generated by spheres disposed in radial perforations in the pressure means and against which an adjustable hydraulic pressure is exerted.
