ABSTRACT:
A drive system of a rotating drum (1), where the drum is supported with a flexible support system. The drive system consists of a gear rim (2) and a pinion gear (4) in contact with the gear rim. The driving pinion gear is supported on a moving platform (10). The drum (1) is provided with a guiding rim (5) and a guiding wheel (6) rolling against it and supported on the same platform as the driving pinion gear. The sum of the outer diameters (D.sub.2 and D.sub.1) of the guiding rim (5) and the guiding wheel (6) is equal to the sum of the pitch diameters of the gear rim (2) and the driving pinion gear (4). The guiding wheel (6) can be pressed against the guiding rim (5) to maintain the right clearing between the teeth of the pinion gear (4) and the gear rim (2) when the center of the drum (1) is moving.
