Abstract
Apparatus for transporting rod-shaped tobacco smoke filters, which contain and/or carry particles of charcoal and/or other particulate tobacco smoke filtering and/or flavoring material, wherein a sender directs a series of successive filters lengthwise into a pneumatic conduit extending toward or into a receiving station. A section of the conduit ahead of the receiving station is provided with openings communicating with a collecting chamber. A duct which extends along the section of the conduit is provided with orifices serving to direct jets of a pressurized gaseous fluid into the openings to thus expel loose particles and/or particles adhering to the external surfaces of filters into the collecting chamber. The latter discharges collected particles by gravity flow.
