<p>Drive unit (1) is installed so that it partially slides on a fixed sub-structure (11). Preferred Features: Coupling units are used to couple a winding core (3). A motor (4) is fixed on the sub-structure and a catch (6) provided with a braking unit (5) is arranged on a sliding unit (14). The sub-structure is structured so that radial forces are not completely transferred to a motor bearing (13) as a result of run of the winding core.</p> |
