In the method and device 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 a pressing device (3) which is in contact with the surface of the rotating reel (R) and has 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 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).
A Method in connection with a reel-up of a paper web provided with a rotating reel spool (2) around which a reel (R) has been formed from the paper web (W) passed to the reel-up, wherein in the method the 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, wherein 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 before the press member (3b) in the direction of rotation 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 (R) than the peripheral surface of the reel (R) and the guiding member (3a) is located under the angular distance of 30° from the press member.
A device in connection with a reel-up of a paper web, comprising a rotating reel spool (2) and around the same a reel (R) formed from the paper web (W) passed to the reel-up, wherein the device can be arranged in contact with the surface of the rotating reel (R), said device comprising a press member (3b) forming a nip with the peripheral surface of the reel and rotating substantially at the same surface speed therewith, wherein in addition to the press member (3b), the device comprises a guiding member (3a), separate from the press member (3b), which can be transferred in the operating position adjacent to the peripheral surface of the reel or in contact with the same to guide the final free end of the web, i.e. a tail (H) moving along with the rotating motion of the reel, against the peripheral surface of the reel (R), wherein the guiding member (3a) is in the operating position within a distance from the press member (3b) in the direction of the perimeter of the reel and is in contact with the tail (H) and/or with the peripheral surface of the reel (R) before the press member (3b) in the direction of rotation of the reel and the surface of the guiding member (3a) that is located opposite to the reel is arranged to have a lower speed in the direction of motion of the peripheral surface of the reel (R) than the peripheral surface of the reel (R) and the guiding member 3(a) is located under the angular distance of 30° from the press member.
