Abstract
A method for manufacturing filter-tipped cigarettes, in which a band is wound on the end of the cylinder of tobacco and on the filter tip so as to encircle them and connect them together, wherein, on the path followed by the paper serving to constitute the band before winding and connection, the paper is slit longitudinally and the two edges of the slit are spaced apart in the direction of the longitudinal axis of the cigarette, as a function of the desired rate of dilution of the smoke.
