Abstract

Filter tipped cigarettes are produced by dividing a continuous tobacco stream into alternate sections having respective lengths corresponding to a double cigarette filler and a double filter portion. The double filter portion sections are removed from the stream to leave spaced double filler sections which proceed to a position where double filter portions are inserted in the gaps left by the removed sections. The stream of alternating tobacco sections and filter portions is continuously wrapped and subsequently cut at the middles of the tobacco sections and filter portions to produce individual filter cigarettes. The sections of tobacco removed from the continuous stream may be returned to the stream.
