Patent number: 6578583Abstract: In an apparatus for making and inspecting a multi-component cigarettes, each cigarette including two or more different components arranged relative to one another, the apparatus includes a device for advancing a web in a first direction. The apparatus further includes a device for positioning at least two different components of a cigarette relative to one another on the web as the web advances in the first direction. The apparatus further includes a garniture device for wrapping the web around the at least two different components by moving opposite edges of the web transversely to the first direction such that, at a closure point in the garniture device, the opposite edges overlap each other. The apparatus further includes an imaging device disposed upstream of the closure point for generating an image of the at least two different components.Type: GrantFiled: January 16, 2001Date of Patent: June 17, 2003Assignee: Philip Morris IncorporatedInventors: Barry Scott Smith, Michael J. Mullins

Publication number: 20030062054Abstract: The outfeed unit of a cigarette maker establishes a feed path along which at least one cigarette rod is caused to advance in a predetermined direction from the outfeed end of a beam, on which the rod is formed, toward a cutter device by which the rod is divided into sticks constituting single cigarettes; the unit is equipped with a cut-off device located in close proximity to the outfeed of the forming beam, by which the rod is severed and diverted from the feed path, and, at a given point downstream of the cut-off device, with pinch rollers by which a portion of the rod separated through the action of the cut-off device is removed from a final stretch of the feed path between the cut-off device and the cutter device.Type: ApplicationFiled: October 2, 2002Publication date: April 3, 2003Inventors: Davide Dall'Osso, Massimo Sartoni, Fulvio Boldrini

Publication number: 20030010347Abstract: Apparatus for controlled removal of surplus material from one or more tows of tobacco particles, filter material for tobacco smoke or the like employs at least one belt conveyor for each stream. The outer side of such belt conveyor is provided with recesses which receive particulate material at the stream forming station or stations. Each stream is equalized by a discrete trimming device which employs a pair of cooperating rotary knives having circular cutting edges and serving to remove the surplus prior to compacting and wrapping of the thus obtained rod-like filler or fillers into web(s) of cigarette paper of the like. The material which has entered the recesses of the belt conveyor(s) contributes to greater density of the corresponding portions of the fillers or fillers, and such densified portions are severed by a cutoff to be located at the ends of plain cigarettes or at the tobacco-containing ends of filter cigarettes.Type: ApplicationFiled: July 9, 2002Publication date: January 16, 2003Inventors: Andreas Ducci, Wolfgang Steiniger, Peter Schumacher, Harald Nittscher, Clemens Schmick

Patent number: 5735292Abstract: A method and device for the production of filter tip bands for ventilated cigarettes, according to which a continuous strip is advanced along a pre-set feed path, an adhesive substance is applied to the strip using a gumming device, defining on the strip itself a periodic succession of gummed areas alternated with non-gummed areas and the strip is cut using a cutting device according to transversal lines at pre-set intervals defined by the gummed areas to produce the bands. A control device controls the timing between the gumming device and the cutting device. The timing is compared with a pre-set value and is corrected, using a correction device in order to eliminate any variation of the pre-set value.Type: GrantFiled: October 7, 1996Date of Patent: April 7, 1998Assignee: G.D. S.p.A.Inventor: Fiorenzo Draghetti

Patent number: 5067498Abstract: An apparatus for cutting and forming tubular members useful for positioning heat sources inside a smoking article is disclosed. The tubular members are carried by a plurality of fluted drums from one operation to the next. The tubular members are cut to the desired size by a plurality of rotating circular knives. The ends of the tubular members are then formed by one or more dies that are caused to move into contact with the ends of the tubular members.Type: GrantFiled: July 25, 1989Date of Patent: November 26, 1991Assignee: Philip Morris IncorporatedInventors: Jack C. Wheless, Billy J. Keen, Jr., Renzer R. Ritt, Sr.

Patent number: 4926887Abstract: Apparatus for manipulating plain cigarettes between the cutoff of a cigarette making machine and the next-following machine, such as a filter tipping machine, has an elongated guide with a prismatic channel for advancement of successive plain cigarettes along a path which is open from above. In order to prevent the cigarettes from rising in the guide, a stabilizing element in the form of an inverted channel-shaped member is placed in front of the guide at a level above the path of cigarettes and downstream of the last tube of the cutoff.Type: GrantFiled: December 29, 1988Date of Patent: May 22, 1990Assignee: Korber AGInventors: Jochim Myohl, Alfred Kasparek

Patent number: 4259130Abstract: A continuous strand consisting of loose filamentary and/or fibrous material is brought into engagement with a conveying and forming belt in at least approximately tension-free condition by means of at least one continuously moving conveying element which extends into the strand-gripping zone of the conveying and forming belt and which engages the interior of the strand. Next the strand is enveloped and brought to the desired cross-section by said belt. After achieving the desired cross-sectional form of the strand, the strand material is interfixed. The thus formed form-stable rod is then divided into rod-shaped portions by a cutting-device.Type: GrantFiled: December 12, 1978Date of Patent: March 31, 1981Inventor: Jean-Pierre Lebet
