ABSTRACT:
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.
