The vertical lamellae can be rotated about their axes by means of a rotating device. This rotating device consists of an axially toothed driver shaft (1) and, situated in the trolley (2), a circle-segment-shaped crown gear (3') on a crown-gear shaft (3) which is positioned obliquely in relation to the lamella shaft. The trolleys (2) can be displaced along a support strip (not shown) and can, as a result of the oblique position of the crown-gear shaft (3), be pushed close against one another. The lamella is supported by the crown-gear shaft (3). <IMAGE> |
