A roller arrangement with a deflection compensation roller and a counter roller. The deflection compensation roller has a shell through which a hydrostatic, support device is supported on a carrier. The shell-ends are each supported on a ring bearing which is guided in an action plane and is radially adjustable and can be loaded by a force in the slide direction. The shell-ends can each be loaded by a torque which has an axis perpendicular to the action plane. In this way the deflection of the shell can, be matched to be proportionate to the deflection of the counter roller.

Why it's free to use
- Filed February 15, 1994 and granted November 18, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 15, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 15, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
