A conveyor system for a multi-layer stream of cigarettes or the like includes a buffer reservoir (32) and a variable length elevator (12) for transferring cigarettes between a main conveyor (10) and the reservoir. The elevator (12) has a movable lower end (22,24) carrying a transfer conveyor (30) which rises and falls with the state of fill of the reservoir (32). The reservoir (32) comprises a rotatable drum (34) carrying an helical track (36). Drive devices (40,46) for the drum (34) and for the movable end (22,24) of the elevator (12) are synchronized and the conveying speed of the elevator is adjusted to compensate for movement of its lower end (22,24).
