In the method in connection with a reel-up of a paper web there is a rotating reel spool (2) around which a reel (R) has been formed from the paper web (W) passed to the reel-up. In the method web (W) passed to the reel is cut, and the surface layers of the reel are bound by means of a press device (3) which is in contact with the surface of the rotating reel (R) and comprises a press member (3b) forming a nip with the peripheral surface of the reel and rotating substantially at the same surface speed therewith. In addition to using the press member (3b), the final end, i.e. tail (H) of the web that travels along with the rotating motion of the reel is guided against the peripheral surface of the reel (R) by means of a guiding member (3a), which is located within a distance from the press member (3b) in the direction of the perimeter of the reel and whose surface that is located opposite to the reel has a lower speed in the direction of motion of the peripheral surface of the reel than the peripheral surface of the reel (R).

L'invention concerne un procédé associé à une enrouleuse de bande de papier, comprenant un tambour rotatif (2) autour duquel est formé un rouleau de papier (R) à partir de la bande de papier (W) passée sur l'enrouleuse. Selon ce procédé, la bande de papier (W) passée sur le rouleau est coupée, et les couches de surface du rouleau sont liées au moyen d'un dispositif de presse (3). Ce dispositif, en contact avec la surface du rouleau rotatif (R), comprend un élément de presse (3b) formant une ligne de contact avec la surface périphérique du rouleau, et tournant sensiblement à la même vitesse de surface. En plus de l'utilisation de l'élément de presse (3b), l'extrémité finale, c'est-à-dire la queue (H) de la bande de papier se déplaçant avec le mouvement rotatif du rouleau, est guidée contre la surface périphérique du rouleau (R) au moyen d'un élément de guidage (3a) situé à une distance de l'élément de presse (3b), dans la direction du périmètre du rouleau, et dont la surface située à l'opposé du rouleau possède une vitesse inférieure, dans la direction de mouvement de la surface périphérique du rouleau, que la surface périphérique du rouleau (R).
