Abstract
In the method for controlling reeling in a reel-up of a paper web, a paper web (W) is guided via a rotating reeling cylinder ( ) around a reel spoil ( ) into a reel (R) in such a way that the paper web (W) is passed onto the reel via a nip (N) between the reeling cylinder ( ) and the reel (R). The paper web (W) running onto the reel is subjected to a load by means of actuators of the reel-up, which load affects the structure of the reel and is controlled by means of measured variables determined during the reeling process. A reel density is used as the measured variable, the reel density being determined during the reeling process continuously or at intervals, wherein it is possible to implement a closed control loop.
