The belt (1) is wrapped round at least two friction rollers (2, 3) rotating in the same direction and coupled through a spur wheel gear (6) which is off-set axially parallel. A deflecting roller (10, 11) is provided on a side of the friction rollers facing the wall (8) so that on the one hand the belt leaves the friction rollers with parallel extension to the wall and on the other a section of the belt lying at the front in the wind-up direction is then guided with a deflection substantially at right angles to the recess (9) of the wall |
