Abstract
A cigarette testing device comprises a conveyor drum which is arranged to carry cigarettes sideways through a testing station, and which includes a pair of axially spaced sets of sprocket teeth, the cigarettes being carried in the recesses between the teeth; a suction or pressure chamber which is mounted adjacent to the conveyor drum and is arranged to communicate with spaces formed between the two sets of sprocket teeth, so that at least part of each cigarette is surrounded by predetermined suction or pressure during testing; a second pair of rotating axially spaced sets of sprocket teeth which overlap with the first pair of sprocket teeth so that the cooperating sprocket teeth together form two axially spaced seals around each cigarette restricting communication between the chamber and atmosphere; and a device for sending the air flow through the wrapper of each cigarette produced by the suction or pressure in the chamber.
