Abstract
The invention relates to a batch washing machine (1) with at least one rotatably supported and driven cylinder (2, 3), wherein several washing compartments are formed, through which the laundry is passed step by step. For this purpose, the cylinder (2) is supported by rollers (6, 7) at its two ends (4, 5) and is also driven at one or both support points. In the construction of a batch washing machine with a twin-shell cylinder, the outer cylinder (3) is stationary, while the inner cylinder (2) extends at both ends (4, 5) over the outer cylinder (3) and is supported and driven at this projection (23). Therefore, on the projection (23) a stepped annular flange (10) is fastened, which has an annular groove (11) for guiding the support rollers (6, 7) and immediately next to it a sprocket wheel (12) for the chain (9).
