Due to the specific arrangement of the driver elements to each other in this respect also a very uniform shape of the driver elements is achieved. Due to the concentric arrangement of the specifically shaped, namely at least crescent-shaped curved entrainment elements, the gentler engagement and entrainment of the laundry items is still significantly favored. For the circumferential direction thus a shuttle-shaped geometry is thus created quasi by this specific shape of the driver elements, which is formed quasi stepped by the plurality of driver elements, so that the picking up and the entrainment process can be done much gentler.
