Abstract
A method of transporting rod-shaped tobacco smoke filters, which carry solid particles, along an elongated path from a sender to a receiving station, includes transporting the filters from the sender to the receiving station through the predetermined portion of the path. A plurality of jets of a pressurized gaseous fluid is directed across a predetermined portion of the path to expel from the portion of the path solid particles which are separated or separable from the filters. The expelled particles are collected in a chamber outwardly adjacent the predetermined portion of the path. The collected particles are evacuated from the chamber.
