Abstract
A cigarette testing apparatus wherein the cigarettes are transported in axially parallel peripheral flutes of a testing drum toward, past and beyond a testing station. A wobble plate is adjacent to one end of and rotates with the drum and supports a set of sleeve-like elastic sealing elements each of which is slipped onto the adjacent end of a cigarette when it approaches the testing station. The sealing elements are surrounded by resilient annular clamping members which tend to reduce their inner diameters and automatically compel the respective sealing elements to sealingly engage the peripheries of the inserted ends of cigarettes at the testing station. Pivotable cams are provided on the wobble plate to expand the clamping members downstream of the testing station in order to permit extraction of the ends of tested cigarettes from the sealing elements and insertion of untested cigarettes into the respective flutes.
