Abstract
In the method for controlling the structure of a reel, a continuous paper web (W) is reeled around a reel spool ( ) to form a reel (R), and one or more variables are measured from the web (W). When a particular, predetermined change occurs in the variable, the lateral oscillation of the web is changed, by means of which the web is guided to different locations in the reel (R) in the axial direction of the reel spool ( ). The change can be implemented by starting the oscillation or by changing the oscillation in progress. The change can be implemented on the basis of the changes in the transverse profile of the web (W).
