Abstract: Trays containing parallel rod-like articles are unloaded by rotation until the trays are at least partially inverted, the rotation being about an axis parallel to the articles. In one arrangement a pair of tray carriers is rotatable to successively invert a full tray over delivery conveyors and to return an empty tray. One of the conveyors is also rotatable about the same axis. A removable slat retains the articles in the full tray until it is completely inverted. In another arrangement a full tray is received in a bracket in which it is moved to a tilted position for unloading. A pivoted closure member is provided for the open top of the tray and this also serves as a barrier for the unloading articles.

Abstract: Packet handling apparatus includes a conveyor for moving packets in line from a delivery station and a reversible accumulator for receiving batches of packets from or returning batches to the conveyor according to whether supply exceeds demand or vice versa. Gates for supplying movement of packets on the conveyor are provided at the exit from and entry to the accumulator. The conveyor section adjacent the accumulator is separately drivable so that it may be temporarily stopped to create a gap between packets for insertion of the exit gate prior to transferring a batch of packets to the accumulator. Guides may be provided upstream and downstream of the accumulator for moving packets from a flat to an upright condition and vice versa, respectively.
