Abstract
In the treatment process of a paper web, the paper web travels via a surface journalled rotatable, such as a peripheral surface of a cylinder or a roll, and the treatment process is controlled with an adjustment and control unit. The bearing arrangement used for the moving surface is a bearing whose operation is maintained by supplying control energy therein, wherein the information obtained from the control energy of the bearing is used in the adjustment and control unit to control the process. The bearing which is used can be a magnetic bearing and the process which is controlled can be reeling or winding or calendaring.
