Abstract

A deflection-compensated roll for use in a calender, comprising a stationary axle upon which is rotatably mounted a shell, characterized in that: The roll comprises at least two mutually independently controllable compensation means, one of the compensation means consisting of a piston provided with a slide shoe which abuts on the inner surface of the shell, the piston being a continuous stip-like piston extending over the entire length of the deflection-compensated roll, the one compensation means substantially compensating for the deflection due to the proper weight of the roll, and the other of said compensation means consisting of a pressurizable ring sector shaped gap between the shell and the axle, the other compensation means substantially compensating for the deflection caused by the line pressure loading of the calender nip.
