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.

Abstract: In order to feed a stream of filter rods forward at regularly spaced intervals a substantially continuous stream of rods is fed to a pair of opposed belts which grip the sides of the rods and accelerate them so as to space them apart. The spaced apart rods may then be accurately fed forward by a timing device in the form of a wheel having extending fingers which engage behind the rods and feed them forward at a controlled speed. A second pair of belts may be positioned between the first pair of belts and the timing device, these belts gripping the rods at the top and bottom. The continuous stream of rods is preferably formed by successively stripping groups of rods axially from a fluted drum.
