ABSTRACT:
A machine for testing the presence and/or packing of cigarettes (11) in a group (10) comprises a housing 16 mounting a plurality of spring biased, axially displaceable tappets (13), (14) and (15) arranged in rows corresponding to the cigarette group alignment. Each row of recesses (25) for the tappet control heads (22) is provided with a pair of linear control ducts (27), (40); (28), (41); (29), (42) axially displaced relative to the tappets. If a tappet is fully displaced by engagement with an acceptable cigarette the inner duct (27), (28) or (29) will be opened and the outer duct (40), (41) or (42) blocked, and the full spring return of a displaced tappet will open the outer duct and block the inner duct. The partial return of a tappet, as a result of particle jamming, will leave both ducts blocked, however, and generate an appropriate error signal, as will the complete non-return of a displaced tappet.
