The invention concerns a method in winding of a web in a centre-drive winder, wherein the roll that is being formed is loaded and/or supported by means of a rider roll unit (40) whose position can be varied and which consists of at least two rolls (42). In the method, the force that is applied by the rider roll unit (40) to the roll face in the radial direction and/or the distribution of said force between the rolls (42) in the rider roll unit (40) is /are measured by means of a detector of detectors (31...36) directly connected with the winding head of the rider roll unit (40). The nip force of the rolls (42) in the rider roll unit (40) and/or the distribution of said nip force is/are regulated on the basis of the measurement signal given by the detectors.

L'invention concerne un procédé permettant d'embobiner une bande dans une bobineuse à entraînement central. Le rouleau en cours de formation est chargé et/ou supporté au moyen d'une unité à rouleaux presseurs (40) dont la position peut varier et qui comprend au moins deux rouleaux (42). Selon le procédé, la force appliquée par l'unité à rouleaux presseurs (40) sur la face du rouleau dans le sens radial et/ou la répartition de ladite force entre les rouleaux (42) se trouvant dans l'unité à rouleaux presseurs (40) est/sont mesurée(s) au moyen d'un ou plusieurs capteurs (31...36) directement connecté(s) à la tête d'embobinage de l'unité à rouleaux presseurs (40). La force de serrage des rouleaux (42) se trouvant dans l'unité à rouleaux presseurs (40) et/ou la répartition de ladite force de serrage est/sont régulée(s) en fonction du signal de mesure émis par les capteurs.
