Abstract
The lower ends of several ducts which dispense layers of parallel cigarettes are located at different levels adjacent the path of movement of a stepwise advancing chain with receptacles for multi-layer arrays of cigarettes which are to be draped into blanks for conversion into cigarette packs. A discrete endless conveyor is installed between the lower end of each duct and the receptacle which registers with such duct, and each conveyor has one or more pushers serving to transfer layers of cigarettes into the registering receptacles. Each conveyor is driven by a discrete motor, and the conveyors can be started and arrested in a predetermined sequence to ensure that each receptacle which registers with a duct is empty when the apparatus is idle, and that each receptacle which advances beyond the last duct contains a full array of cigarettes.
