Abstract
Single cigarette rejection, particularly in a passage (10) between vanes (12) in a cigarette packing machine hopper, is performed by axial ejection of faulty cigarettes using suction generated by exhausting high pressure air adjacent an ejection aperture (22) in an end wall (16) of the passage. A short cylindrical casing (24) is located around the aperture (22) and defines a duct (28) through which the cigarette is ejected. The casing (24) includes an annular pressure chamber (32) and venturi orifice (34) for generating suction in the duct (28).
