<p>A reel-up (1) having a driven surface winding drum (4); two rails (5) to support the reeling drum (7); secondary carriages (17) movable linearly along the rails (5) and provided with press devices (19) to press against a reeling drum (7) to maintain a predetermined linear pressure in the nip between the surface winding drum (4) and the paper reel (6) as it increases in size; and drive means (50) for central driving of the reeling drum (7) comprising a coupling device (67) for connection to one of the coupling devices (9) of the reeling drum (7). According to the invention the central drive means (50) is mounted to one of the secondary carriages (17) to be moved together with this, and positioning means (27) are disposed on the secondary carriages (17) to abut against the reeling drum (7) on the side facing the surface winding drum (4) in order, together with the press devices (19), to fix the reeling drum (7) so that its axis of rotation coincides with that of the coupling device (67) of the central drive means (50). Further, the central drive means (50) is axially movable on the secondary carriage (17) in relation to the reeling drum (7) to bring the coupling device (67) of the central drive means (50) into engagement with the opposite coupling device (9) of the reeling drum (7).</p> |
