In the method for controlling the structure of a reel, a continuous paper web (W) is reeled around a reel spool (2) 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 (2). 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).

Dans ce procédé, qui sert à commander la structure d'un bobinage, une bande de papier continue (W) est enroulée autour d'un cylindre de bobine (2) pour former une bobine (R), et une ou plusieurs variables sont mesurées sur la bande (W). Lorsqu'un changement particulier prédéterminé se produit dans cette variable, l'oscillation latérale de la bande est modifiée, de telle sorte que la bande soit guidée vers des endroits différents de la bobine (R) dans le sens axial du cylindre (2) de la bobine. On peut réaliser cette modification en créant l'oscillation ou en modifiant l'oscillation en cours. Cette modification peut être réalisée sur la base des changements apparaissant dans le profil transversal de la bande (W).
