  • Patent number: 4790333
    Abstract: A cigarette transfer apparatus is used for transporting the cigarettes to a packaging machine when the cigarettes are supplied periodically, especially in trestles (11), and this apparatus consists of an intermediate container (13) with several conveyors driven at increasing speed in the conveying direction, namely a receiving conveyor (22), an intermediate conveyor (24) and a discharge conveyor (23). A continuous cigarette stream (26) is formed within the intermediate container (13), and reductions (valley 39) in the cross-section of this cigarette stream as a result of an interrupted supply of cigarettes are compensated by a controlled drive of the conveyors, while ensuring continuous delivery to the packaging machine. The cigarette stream (26) is loaded at the top by a closely matching cigarette cover (40) consisting of individual rollers (41).
