The invention relates to a screen and to the use thereof for a cleaning device of a combine harvester, comprising a frame (10) in which multiple identical lamellae (11) are arranged one behind the other, said lamellae extending transversely to a longitudinal and oscillating direction of the screen and having an angled shape with a folding edge (119) between a part (112) which is used as a wind collector and an upper region (111). The lamellae have the following features: a) the angle (ß) formed by the upper (111) and the lower part (112) of the lamella lies between 125° and 150°, preferably between 130° and 140°, b) the upper termination edge (114) has multiple mutually spaced protuberances (115) with a semicircular edge (116), the secant (117) of which has a length (I1) between 20 mm and 40 mm, preferably 25 mm to 35 mm, and a maximum height (h1) (measured in the vertical direction relative to the secant) of 6 mm to 12 mm, c) the upper part (111) has a total height (h2) of 25 mm to 45 mm, preferably 30 mm to 35 mm, said height being measured without the protuberances (115), d) the lower part (112) has a total height (h3) of 16 mm to 30 mm, preferably 18 mm to 24 mm, e) the upper parts (111) of successive lamellae can be pivoted onto a common plane, wherein the protuberances (115) of a lamella have a spacing (a) of at least 1 mm, preferably a spacing of 2 mm to 20 mm, from the lower folding edge (119) of the adjacent lamella (11), and f) the lamella (11) can be pivoted out of the position described in e) by an angle (α) of up to 50°, preferably 45° to 35°.
