Description

technical field

[0001] The invention relates to a device for exerting a force on a component of a fiber web processing machine. Furthermore, the invention also relates to a method of exerting a force on a component of a fiber web processing machine. Background technique

[0002] A device of this type and a corresponding method are known from DE 112005002147 A1. A similar device is also described in patent document US4332192.

[0003] In fiber web processing machines, for example for the manufacture and / or processing of paper, board or tissue paper or textiles, the fiber web is subjected in different process steps (for example drying or calendering) between two rolls forming a roll nip extrusion. Therefore, in most cases one of the rollers is arranged to be movable, while the other roller is fixedly mounted. With the aid of devices of this type, forces can be exerted on the movable rolls in order to vary the pressing force in the roll gap, the so-called roll gap pressure ...
