摘要

The device has a deflection roller (3), a drive roller (4) and a running belt (5) enclosing the rollers. Two supporting roller arrangements lie transverse to a running direction of the belt and comprise supporting rollers that are supported at a pendulum, where the arrangements act on the belt. The arrangements are arranged at separate retainers (20, 21), where the retainers are pivotable independent of each other. A damping unit and/or a spring unit is supported at a frame (11), where the deflection roller, the drive roller and the retainers are arranged at the frame.
