<p>The invention concerns a method in reeling, wherein, when the jumbo roll (20) becomes full, a new reeling drum (22) is brought by means of transfer members (32) into the stand-by position and accelerated to the web speed. The jumbo roll (20), connected to the centre drive (44), is transferred by means of the jumbo-roll transfer device (45) to the exchange position. The new pre-accelerated reeling drum (22) is lowered onto the rails (10), and the exchange is carried out in a way in itself known. Hereupon the full jumbo roll (20) is slowed down and the transfer device (45) for full jumbo roll (20) is shifted to the new reeling drum (22), and the centre drive (44) is connected to the new reeling drum (22). The invention also concerns a reel-up, comprising a first revolving roll (15) and a second revolving roll (20), the web (W) being reeled in said reel-up, by the intermediate of the first roll (15), onto the second roll (20) through a nip (N). The reel-up is provided with transfer members (32) for bringing a new second roll (22) to the initial position of reeling and with a transfer member (45) for transferring the full second revolving roll (20), which is provided with centre drive (44), to the exchange position. <IMAGE></p> |
