Patent number: 8201564Abstract: Fibrous material suitable for incorporation into filter elements of smoking articles such as cigarettes are impregnated with additives and agents such as flavorants, flavorant-enhancers and/or free radical scavengers. The fibrous material is contacted with the additive dispersed in a high pressure gas or supercritical fluid (SCF) held at elevated pressures. The high pressure gas or SCF swells the fibrous matrix and enables the additive to be incorporated within the matrix. When pressure is reduced, the gas or SCF vaporizes and leaves the additive embedded in the fiber interstices. As a result, the additive is slowly released over a finite period of time. When incorporated into a cigarette filter, the additive is released at a desired rate from the interior of the fibrous filter into the cigarette smoke.Type: GrantFiled: December 4, 2006Date of Patent: June 19, 2012Assignee: Philip Morris USA Inc.Inventors: Mark A.

A liquid flavorant is introduced into the passageway at a desired flow rate and the strand of material carries the supplied liquid flavorant out of the positioning device at a rate substantially equal to the desired flow rate. A portion of the passageway can form a bath of the liquid flavorant supplied to the passageway through a separate inlet at approximately atmospheric pressure. A portion of the positioning device guides the continuous strand of material through the bath, or guides the strand to pass along the bottom of the passageway, and the saturated or partially saturated strand of material then exits from an outlet of the passageway to a point in the path of filter tow material that is being converged to form a filter rod.Type: ApplicationFiled: February 24, 2010Publication date: June 17, 2010Inventors: Robert C.

Patent number: 7713184Abstract: Process and apparatus for the mass production of compound cigarette filters function to deposit granular filter material into the open ends of vertically oriented filter tubes. Predetermined amounts of diverse granular material are withdrawn by suction from sources of such material, and these amounts are deposited into the tubes. Solid filter segments seal the granular material within the tube. After one half of each filter tube is filled with granular material and sealed, the tube is inverted and the opposite end is filled in substantially the same manner. When cut in half each filter tube produces two cigarette filters.Type: GrantFiled: December 22, 2008Date of Patent: May 11, 2010Assignee: Philip Morris USA Inc.Inventors: George R. Scott, Martin T. Garthaffner, Steven F. Spiers, Steven R. Rinehart, Barry S. Smith, James D. Evans

Patent number: 7691043Abstract: A filter making apparatus includes a positioning device having a passageway therethrough, with the passageway guiding a continuous flavor element such as a continuous strand of textile material from an inlet of the passageway to an outlet of the passageway. A liquid flavorant is introduced into the passageway at a desired flow rate and the strand of material carries the supplied liquid flavorant out of the positioning device at a rate substantially equal to the desired flow rate. A portion of the passageway can form a bath of the liquid flavorant supplied to the passageway through a separate inlet at approximately atmospheric pressure. A portion of the positioning device guides the continuous strand of material through the bath, or guides the strand to pass along the bottom of the passageway, and the saturated or partially saturated strand of material then exits from an outlet of the passageway to a point in the path of filter tow material that is being converged to form a filter rod.Type: GrantFiled: July 26, 2005Date of Patent: April 6, 2010Assignee: Philip Morris USA Inc.Inventors: Robert C.

Patent number: 7674218Abstract: A filter component cutting system comprises a supply hopper of elongate filter rods and a cutting drum with spaced apart flutes on an exterior surface of the drum for receiving the elongate filler rods. A transfer mechanism receives the elongate filter rods from the supply hopper and delivers the rods to the flutes on the cutting drum. At least one cutter adjacent the cutting drum functions to cut the filter rods in to individual filter components as the cutting drum rotates.Type: GrantFiled: December 28, 2006Date of Patent: March 9, 2010Assignee: Philip Morris USA Inc.Inventors: James D. Evans, Steven R. Rinehart, G. Robert Scott, Steven F. Spiers

Patent number: 7654945Abstract: Cigarette filter rods having individual objects positioned at predetermined intervals therein are prepared by transferring the individual objects from a rotating horizontal pan to a rotating vertical wheel and then depositing the object into a web of filter tow. Each object is positioned within the moving web of tow. The web filter material and the objects positioned within the web are introduced into a rod-forming unit wherein the rod is formed. The rate of feed of the filter tow, the rate of rotation of the horizontal pan and the vertical wheel are controlled relative to one another such that objects are positioned at predetermined intervals along the rod. Cigarette filter elements having well controlled amounts of flavorant contained therein can be made from the rods.Type: GrantFiled: August 4, 2006Date of Patent: February 2, 2010Assignee: R.J. Reynolds Tobacco CompanyInventor: Philip Andrew Deal

Patent number: 7588524Abstract: Method and device for producing filter rods of the tobacco-processing industry. The method includes combining and mixing fibers of finite length of two different fiber types, and separating the combined and mixed fibers. The combining and mixing occurs directly before the separating.Type: GrantFiled: April 3, 2007Date of Patent: September 15, 2009Assignee: Hauni Maschinenbau AGInventors: Stephan Wolff, Thorsten Scherbarth, Soenke Horn, Irene Maurer, Alexander Buhl, Jann De Boer

Patent number: 7578777Abstract: Filter elements made up of least two axially aligned plugs are advanced in succession by a feed unit along a first path and in a first direction, with the plugs oriented along a second direction transverse to the first direction, toward a garniture section extending along a second horizontal path and in a third direction, on which they are formed into at least one continuous rod which is then divided up by a rotary cutter into single composite filters. A transfer unit linking the feed unit and the garniture section comprises a conveyor, rotatable about a first axis parallel to the second direction, equipped with carriers each presenting at least one slot designed to admit one filter element; the single carriers are pivotable independently relative to the conveyor about a second axis parallel to the first axis, and about a third axis transverse to the first axis, alternating between positions in which the slot extends parallel with the second direction and with the third direction.Type: GrantFiled: March 21, 2006Date of Patent: August 25, 2009Assignee: G.D S.p.A.Inventors: Fiorenzo Draghetti, Salvatore Rizzoli, Emanuele Giovannini
