Abstract
A unit for feeding cigarettes to a packer machine is equipped with a hopper containing a mass of cigarettes and a device serving to compensate the depletion of the mass as groups of cigarettes are removed from the hopper and directed into a plurality of boxes carried and transported by a conveyor. The compensating device is located internally of the hopper and comprises an articulated mechanism designed to create a movable wall, also a pair of lateral conveyors converging toward the articulated mechanism, its operation being coordinated with that of a further device by which the groups of cigarettes are removed from the hopper, in such a way as to vary the capacity of the hopper according to the volume of cigarettes removed.
