The system has setting elements (7-9,11) forming a first closed unit (1) with a lever setting part (9) with a long and short lever arm and located laterally in the region of the rollers (41,42). The drive motor (19) and the coupling (20) form a second closed unit (2). The second unit is spaced apart from the first unit. The setting force produced by the drive motor engages the long arm of the setting part. The setting elements also have a manual setting arrangement (8,16). The coupling is a settable clutch. |
