ABSTRACT:
A method and apparatus for opening cigarette packs involving minimal contact with the cigarettes in the pack and little likelihood of damage or degradation of the tobacco contained in the cigarettes. The invention includes conveying packs to a first location where they are received, moving the packs to a second location where they are pressurized and expanded, moving the pressurized expanded packs to a third location where one end is cut off, moving the packs to a fourth location where impulse is applied to the pack as a whole, resulting in the transfer of the pack to a fifth location, where the motion of the pack itself is stopped, but the inertia of the cigarettes themselves is conserved sufficiently that they are transferred to a conveyance for further processing. The empty packs are disposed of at a sixth location. The method and apparatus is intermittent, involving regular starting and stopping motions. The device employed to expand the pack does not move transversely relative to the pack during the expansion process, thus limiting the likelihood of damage to the expansion device.
