Abstract
A cigarette packing machine with a plurality of passageways leading from a hopper, includes an ends testing device (16, 16a) for individual cigarettes, so that faulty cigarettes can be rejected from the hopper before the cigarettes are ejected in groups at the bottom of the passageways (2). Leading from the hopper are two channels (6, 8) feeding each of the passageways. In one embodiment of the invention cigarettes are held up for ends testing in alternate channels by suction ports (14) formed in inclined surfaces leading to each passageway. In a second embodiment a set of horizontal reciprocating wires (30, 32) acts as an escapement mechanism.
