Abstract
A method and a device for feeding rod-like articles, particularly cigarettes, carried by trays, to the feed hopper of handling machines, particularly cigarette-packing machines. In order to assure a broad time period to replace an emptied tray and to practically avoid the sudden drop of the cigarettes from the tray into the hopper, two trays in discharge position and aligned to each other in the direction of the hopper length, are arranged over the inlet opening of the hopper. The descent of the cigarettes into the hopper is permitted alternately only from one of the trays until it is emptied, while the other previously emptied tray is replaced with a stand-by full tray. The descent of the cigarettes into the portion of the hopper in register with the tray being emptied, is discontinued and prevented as soon as the tray has been emptied, so that the level of the cigarettes in the corresponding underlying portion of the hopper is maintained just below the lowest layer of cigarettes in the new full tray which is arranged in discharge position as a substitute for the emptied tray.
