The reel-up has a surface winding drum; two rails to support the reeling drum over which the web runs; secondary carriages movable linearly along the rails and provided with press devices to press against the reeling drum to maintain a linear pressure between the surface winding drum and the paper reel as it increases in size; and drive motor for central driving of the reeling drum. The central drive motor is mounted to one of the secondary carriages to be moved together with this, and positioning devices are disposed on the secondary carriages to abut against the reeling drum in order, together with the press devices, to fix the reeling drum so that its axis of rotation coincides with that of the coupling device of the central drive motor. Further, the central drive motor is axially movable on the secondary carriage in relation to the reeling drum to bring the coupling device of the central drive motor into engagement with the opposite coupling device of the reeling drum.
