Abstract
The invention concerns a drive unit (10) for the center-wind reel-up of a paper machine or paper finishing machine, comprising means by which the rotation drive of the motor (11) is transferred to the shaft (19). In its interior, the shaft (19) comprises a transfer shaft (21) rotatable along with the shaft (19), said transfer shaft (21) being fitted to be displaceable on a coupling and uncoupling process in the direction of the longitudinal axis (X.sub.1) of the shaft (19) by means of a cylinder device (22). When the transfer shaft (21) is displaced (arrow L.sub.1) towards the coupling half (23b) of the central drum of the paper web roll (P), the coupling half (23a) of the drive unit attached to the end of the transfer shaft (21) is displaced into engagement with the web roll coupling half (23b). The invention further concerns a hydraulic operating system for the reel-up.
