ABSTRACT:
A method of manufacturing filter-tipped cigarettes, whereby a first and second series of cigarette portions, obtained by transversely cutting two continuous cigarette rods travelling axially at substantially constant speed, are fed by respective transfer members into respective seats on respective first and second receiving rollers arranged side by side and tangent to each other. The portions in the first series are fed on to the first receiving roller in an axially offset position in relation to that in which the portions of the second series are fed on to the second receiving roller, and are fed from the first to the second receiving roller so as to form, inside each seat on the second receiving roller, a pair of coaxial portions the facing ends of which define a gap. A double filter is inserted between the facing ends of the two coaxial portions; is connected to the two coaxial portions to produce a double cigarette; and is subsequently cut to divide the double cigarette into two cigarettes.
