A tumbler body with an oloid hollow body (7) is positioned on two free-moving, endless conveyor belts (8) to receive mixing materials. A strip (10) runs around and is attached to the hollow body (7) limited by two profiles (9). The strip (10) contains, in a positive connection, a driving element (not shown) in form of an endless belt. The profiles (9) sink into the area of the guiding and driving system (11) in between the conveyor belts (8). The system contains and combines the means for guiding the profiles (9) and driving the driving elements. The conveyor belts (8) glide on low-friction tables (12) supported by a frame (14) which is also the attachment point for the guiding and driving system. The frame (14) is supported by a base (15). During the rolling process on the conveyor belts (8), the hollow body (7) has a tumbling motion, during which the profiles (9) in the area of the guiding and driving system (11) sink to their lowest point and the tangents at the profiles (9) are always in the moving direction of the conveyor belts (8) at this lowest point.
