ABSTRACT:
Apparatus for transporting filter rod sections or the like from a first to a spaced-apart second transfer station has a stationary hollow cylindrical core which is surrounded by a rotary drum-shaped conveyor having peripheral flutes and radially inwardly extending suction ports communicating with the flutes. The periphery of the core has an arcuate channel having a width in the range of a fraction of one millimeter and communicating with those ports which travel between the first and second transfer stations. The internal surface of the rotating conveyor constitutes the outer boundary of the channel and defines with the bottom surface of the core in the channel a plurality of flow restrictors each of which connects the inner end of a suction port in the region of the channel with a suction chamber in the interior of the core. This insures that particles of dust or the like cannot settle in the channel and also that suction in the chamber cannot collapse when the outer end or ends of one or more or all ports are free to communicate with the surrounding atmosphere. The core has an arcuate groove which is adjacent to one end of the channel, as considered in the axial direction of the core, and allows for at least substantially unrestricted flow of air from the channel into the chamber.
