Abstract

Moving cigarettes are inspected, particularly in the passages (10, 30) between the vanes (12, 32) in a cigarette packing machine hopper, by an optical ends inspector (74, 76) which is switched by a position detector (84, 86) responding to passage of individual cigarettes. Faulty cigarettes are arrested by a suction aperture (26) or an arrestor are (122, 222) and subsequently rejected from the passage, either in an axial direction or sideways through an opening (116, 244) in the vane. The position detector (84, 86) may activate the suction or arm for arresting the faulty cigarette.
