In the treatment process of a paper web, the paper web (W) travels via a surface jour-nalled rotatable, such as a peripheral surface of a cylinder or a roll (1), and the treatment process is controlled with an adjustment and control unit (9). The bearing arrangement used for the mov-ing surface is a bearing (6) whose operation is maintained by supplying control energy therein, wherein the information obtained from the con-trol energy of the bearing is used in the adjust-ment and control unit (9) to control the process. The bearing (6) which is used can be a magnetic bearing and the process which is controlled can be reeling or winding or calendering.
Au cours du processus de traitement, la bande de papier (W) se déplace par l'intermédiaire d'une surface rotative montée sur palier, telle que la surface périphérique d'un cylindre ou d'un rouleau (1). La gestion du processus est assurée par une unité de réglage et de commande (9). La surface en mouvement est montée sur un palier (6) auquel est transmise une énergie, les données concernant cette énergie étant exploitées par l'unité de réglage et de commande (9) pour gérer le processus. Le palier (6) utilisé peut être du type magnétique et le processus concerner le bobinage, l'enroulage ou le calandrage.
