A cigarette rod making machine wherein the flow of loosely intermingled tobacco shreds, tobacco ribs and foreign objects (such as nuts, bolts, pieces of wire and/or particles of plastic material) is classified to segregate the ribs and foreign objects from the shreds. The ribs are thereupon separated from foreign objects in a sifter and are comminuted in a rotary cutter prior to being readmitted into the flow downstream of the classifying location(s). Successive increments of the flow are converted into successive increments of a stream which carries a surplus of shreds and is trimmed for conversion into a filler which is ready to be wrapped into cigarette paper. The comminuted ribs are admitted into the flow at a location such that they are confined in the central portion of the filler.
A method of making at least one stream of first and second tobacco particles, comprising the steps of accumulating the first and second particles and randomly distributed foreign particles into an elongated flow of particles and advancing the flow along a predetermined path;
Apparatus for making at least one stream of first and second tobacco particles, comprising means for accumulating first and second particles and randomly distributed foreign particles into an elongated flow of particles, including means for advancing the flow in a predetermined direction along a predetermined path;
