The narrower 5 dotted arrow 30 is thrown into the area that meets in wall 18 a, 19 a, 20 a under a substantially conveying direction of the laundry (arrow 31) in front of the congestion larger angle on the washing drum 11 than the rib 24.

The individual driver ribs 18, 19, 20 can ribs 18, 19, 20 thereby form surfaces which are arranged at different inclinations relative to the washing drum 11 in the washing zone with opposite directions of rotation from the washing zone. Have in the washing zone 23 b . according to FIG. 1 have the individual driver ribs. During the rotation of the washing drum 11, 18, 19, 20 acts, for example, in a left-hand direction of rotation, this configuration of the driver ribs 18, and in the washing zone 23c an opposite 19, 20 such that in one direction of rotation, a direction of rotation that is directed to the right is set , according to arrow 21 the laundry through the steeper wall. Washing drum 11 prevented. If the laundry is rotated in the opposite direction as indicated by arrow 22 in the opposite one washing zone, e.g. B. washing zone 23 b, as a result of the set direction. This effect has the consequence that uneven entrainment in the opposite directions of rotation of the washing drum slightly together in the opposite direction of rotation despite the same movement cycles of the washing drum 11 20, so the laundry is in the next following by the driver ribs 18, 19, 20 in the washing-washing zone 23 c is transported further through the opposite rotary drum like a pilgrimage. sense of the driving ribs again completely

This involves 25 ribs 18, 19, 20 each ending in the area of the transport problem in a washing machine, a connection point between individual sheets of the washing drum 11 through radially inward sections 24 a, 2Ab, 24c of the storage ribs,

The passage of laundry from one washing zone. A modified embodiment of the carry-over to the other is shown in FIG. 3 by arrows with dashed ribs is shown in FIG. 4 shown. It is indicated here by the pure and dash-dotted line. At Um- 45 a washing zone 23 of a washing drum is shown schematically in the direction of rotation of the washing drum according to FIG. 11, in which driver ribs 32 are provided, the arrow 27 is the laundry coming from the left, which changes one in the longitudinal direction, namely in the axial direction only by a small distance in the direction of rotation Have cross-section. The idea of the invention of the washing drum 11 through the wide wall 19 b consists in that one of the driver rib 19 is carried along. Namely, when 5 ° side wall 32 a another angle to the longitudinal a certain height of the laundry is reached, it slides axis of the washing drum 11 occupies than the other on the slightly inclined wall 19 b of the mit-side wall 32 b. This also gives entrepreneurial rib 19 downwards according to arrow 28 different conveying strengths when the individual arch sections 24 a, 246, 24 c drive the washing drum 11, so that storage ribs 24 are attached to the entrainment rib 55 the laundry is moved forward like a pilgrim step, pen 19, 20 connected that the inclined wall 19Jb (or 18b, 20b ) inclined wall 19Jb (or 18b, 20b) downward In the illustrated embodiment of the laundry sliding along according to the dashed slave ribs 32, the side surfaces 32 a, 32 & arrow 28 already go into the next following washing zone 60 on a radially inner, preferably arched slide. Here it is through the driver ribs 18, end wall 32 c over. This takes 19, 20 further transported in its width. in the axial direction of the washing drum 11. Simultaneously

When the washing drum rotates in the opposite direction, the radial height of the driver ribs 32 mel according to arrow 29 will decrease due to the steep, narrow in the conveying direction,
