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.

Abstract: A method of forming a row of filter-tip cigarettes at a high speed with a simple device.

Abstract: A cigarette reversing apparatus with a rotating drum having radially extending slots of a width slightly larger than the diameter of a cigarette and of sufficient depth, each slot having at its opposing surfaces a pair of cigarette holding members spaced from each other a distance slightly smaller than the cigarette diameter, these pairs of cigarette holding members being arranged on the circumference of the drum. The cigarettes are fed onto the cigarette holding members and guide elements bring the longitudinal center of the cigarette to the circumference of the cigarette holding members; arcuate guide members provided along the outer circumference of the drum guide the free end of the cigarette so as to turn the cigarette about the point held by the cigarette holding members. A retrieving member takes out the cigarettes from the rotating drum.

Abstract: A cigarette reversing apparatus comprises a rotating transfer drum having a plurality of openings arranged equidistantly along the circle on the end surface of the drum, the openings being communicated with suction holes formed at the bottom of slots which are formed in the peripheral surface of the drum. A control ring faces the openings in the drum and has a suction distribution chamber spanning a cigarette overturning section of the drum. A rotating ring is slidably and rotatably interposed between the transfer drum and the control ring, the rotating ring being eccentric with respect to the drum and having a plurality of communication holes communicating with both the openings and the suction chamber.
