ABSTRACT:
A continuous web (W) is reeled up on a center-drive assisted reeling core (C2, C3) to form a machine reel (R), and the reeling core (C2, C3) moves when the center drive (PD, SD) is coupled to the end of the reeling core. The rotating movement and torque necessary in the center drive (PD, SD) are transmitted from a stationary drive motor (PM, DM) to the end of the reeling core (C2, C3) by a power transmission (T) equipped with one or more joints, wherein the need to move the drive motor (PM, DM) along with the movement of the reeling core (C2, C3) is avoided. In a preferred embodiment of the invention the power transmission (T) is implemented by a belt drive, wherein by selecting the belt transmission in a suitable manner, it is also possible to avoid the need to use a separate gear system.
