ABSTRACT:
A device for manufacturing a filter-tipped cigarette, in which paste coupling paper is wound around a unit comprising two cigarettes laid coaxially with each other and a filter tip interposed between the cigarettes, while the unit is being rotated in a rolling passage defined between a cylindrical drum and a rolling mechanism facing the drum, so that a cigarette having the filter tip and being twice as long as a normal cigarette is made. The rolling mechanism comprises groups of rollers, an endless belt rotatable around the rollers, and a rolling block for supporting the belt to move it near the drum. The mechanism and the drum are in such relative positions that the belt can be moved without being in contact with the drum, when the unit is not supplied onto the drum.
