Abstract
Cigarettes in the peripheral flutes of a rotary drum-shaped conveyor are tested while their end portions extend into elastic tubes which are deformable radially inwardly into sealing engagement with the wrappers of the respective end portions in response to axial deformation directly by the respective end faces of the conveyor. The tubes are mounted on two ring-shaped carriers which are adjacent to the end faces of the conveyor and rotate about axes which are slightly inclined with reference to the axis of the conveyor so that each tube approaches the conveyor during one-half and moves away from the conveyor during the other half of each revolution of the conveyor and that corresponding carrier. A gaseous testing fluid is admitted into the ends of cigarettes while the tubes are deformed so that they are in sealing engagement with the wrappers of the respective cigarettes. Those annular sections of the tubes which move into actual contact with the wrappers of cigarettes are thinner than the remaining portions of the tubes and are bounded by convex internal and concave external surfaces.
