Packets of cigarettes are delivered from a packing machine to a cartoner in the form of arrays each of which contains a predetermined number of packets. The packing machine discharges discrete packets which are advanced to a gathering station where the packets are assembled into arrays in successive compartments of a stepwise operated first endless conveyor. The first conveyor delivers freshly accumulated arrays into the pockets of a stepwise operated second endless conveyor which delivers a series of arrays to a second station adjacent the cartoner. The second conveyor is set in motion during a first stage of each cycle of the cartoner, and a pusher transfers successive arrays from the respective pockets of the second conveyor during second stages of certain cycles of the cartoner. The frequency of cycles of the cartoner at least equals but normally exceeds of the frequency at which arrays of packets are assembled in the compartments of the first conveyor. In order to compensate for such discrepancy, the accumulation of packets into arrays at the gathering station is monitored and the second conveyor is caused to advance by a step without receiving an array from the first conveyor when the monitoring step indicates that the accumulation of a fresh array cannot be completed prior to completion of a preselected portion of the corresponding cycle of the cartoner.

A sender propels filter rod sections at a constant or at a variable frequency into a pneumatic conveyor which delivers the sections into the magazine of a receiver serving to store a supply of sections next to a filter tipping machine. The operation of the sender is interrupted for a fixed or for a variable interval of time after the sender propels a preselected number of sections. The intervals of operation and idleness of the sender are regulated in dependency on fluctuations of the quantity of sections in the magazine of the receiver. The frequency at which the sender propels the sections can be varied by varying the speed of a fluted rotor which transfers sections from a source to the sender, and the ratio of the intervals of operation and idleness of the sender is determined by several timing pulse generators which receive signals denoting the quantity of sections in the magazine and control the operation of a blocking device which can prevent the transfer of sections from the source into the sender.
