  • Patent number: 4225032
    Abstract: The device for the removal of rod-like articles from a hopper in which a bulk supply of articles is provided and a rotating fluted drum is arranged to form the bottom wall of the hopper so that the articles are removed from the hopper by being picked by the flutes of the drum, presents the feature that each flute of the rotating drum has a depth so as to be capable of housing at least two superposed articles. The flutes filled with the articles come out of the hopper zone and a stripper takes out from each flute just one article, while the other article, if two of them were present in the flute, is again inserted in the operational cycle of the flute.
