A method and apparatus for manufacturing a rod of tobacco or the like enclosed by a paper strip is described, wherein a paper strip is supported and transported by a garniture tape and tobacco is deposited on the paper strip. The tobacco is compressed into a tobacco core and the paper strip is closed with its longitudinal edges parts around the compressed tobacco core. A channel is formed in the circumference of the tobacco rod during the compressing by means of an entrance finger with a ridge. A second longitudinal edge part of the paper strip is folded into the channel by a folding element and a first longitudinal edge part is subsequently laid over said channel. |

Cigarettes which yield low levels of visible sidestream smoke upon use employ a paper wrapping material having about 25 weight percent magnesium hydroxide, about 15 weight percent calcium carbonate and about 60 weight percent flax. The wrapping material has an inherent permeability of about 12 CORESTA units and a net permeability of about 100 to about 130 CORESTA units. The wrapping material containing an amount of water soluble alkali metal salt sufficient to provide at least about 35 mg water soluble alkali metal ions per gram of dry base web. The alkali metal salt is such that the wrapping material includes a significantly greater level of potassium ions than sodium ions. the cigarettes, when employed, provide cohesive ash which is not highly flakey. |

Cigarettes which yield very low levels of sidestream "tar" during use comprise a paper wrapper having an air permeability of less than about 10 CORESTA units, and a blend of a tobacco filler material and a second smokable material. The second smokable material preferably includes about 60 weight percent calcium carbonate, about 30 weight percent pyrolyzed alpha-cellulose and about 10 weight percent carboxymethyl cellulose. Such cigarettes, when used, generate very low amounts of sidestream "tar," and hence, very low levels of visible sidestream smoke. |

Cigarettes having low efficiency filters, rods of cut filler having a low packing density, and paper wraps having a high net permeabilities and low inherent permeabilities can yield good taste, low gas phase mainstream deliveries as well as low amounts of visible sidestream smoke. Typical cigarettes have relatively large amounts of volume expanded flue-cured tobacco materials as cut filler, paper wraps containing magnesium oxide and/or magnesium hydroxide, and relatively high levels of air dilution. |

Cigarettes having high nicotine content tobacco cut filler are rendered smooth smoking and palatable by incorporating an organic acid additive therein. For example, a cigarette having a cut filler with a blend nicotine content of greater than 2 percent has at least one organic acid additive incorporated into the cigarette in an amount of greater than 1 percent. Smooth smoking cigarettes yielding good tobacco taste and minimal off-taste are provided when the majority of the organic acid additive is levulinic acid. The levulinic acid can be in a dissociated and/or nondissociated form. For cigarettes having filter elements, at least a portion of the levulinic acid can be present in the filter element. Alternatively, cigarettes can have at least a portion of the levulinic acid provided in the form of nicotine levulinate. Cigarettes having high nicotine content tobaccos and levulinic acid and cigarettes having a salt such as nicotine levulinate incorporated therein can exhibit low FTC "tar" to nicotine ratios while providing a smooth, palatable and flavorful taste. |

A novel cigarette structure is provided which produces an approximately uniform delivery of flavour along its length as the cigarette is smoked. The filler rod of the cigarette has a strip of more highly-flavoured tobacco to one side or to two sides of the rod, with the remainder of the cross-section of the rod being formed of lower flavoured tobacco, and has a higher proportion of the more highly-flavoured tobacco than the lower flavour tobacco at the lighting end. The cigarette filler rod of improved smoking characteristics may be formed by a simplified assembly procedure. |

The segmented cigarette includes combustible inside and outside tubular walls that are spaced from each other by ridges extending therebetween. The inside wall holds a plurality of elongated segments of tobacco aligned end to end. Different tobaccos may be utilized in each segment. The upstream, axial end of each segment is sealed by paper. The inside wall includes a plurality of gas passages therethrough near the axial end seal such that gas from the burning end of the cigarette passes through those passages into the interspace between the outside and inside walls, expands and cools. This cooling and expansion reduces the accumulation of noxious substances in the segments of tobacco downstream. |

An improved composite cigarette comprising a core of lesser quality tobacco smoking material surrounded by an annulus of higher quality tobacco smoking material is described. The improvement resides in the provision of an increased quantity of the annulus material at the lighting end of the cigarette, so as to increase the initial flavor impact and thereby provide more uniform smoke taste characteristics along the length of the cigarette. |

Cigarette rods include four segments of smokable material. First and second segments are positioned at the extreme ends of the rod. The first segment is positioned at the end of the rod to be lit. A third segment is positioned adjacent the first segments, and a fourth segment is positioned adjacent the second segment. The density of the third segment is greater than the fourth segment. The first and second segments can be "dense ends" or "loose ends" relative to the respective adjacent segments. |

Tobacco trimmed from a filler rod is recycled and used in the control of the rod-forming operation. A reservoir vessel is divided into physically-separate chambers, a narrow one of which receives the recycled trimmed tobacco and a wider one of which receives cut tobacco. Tobacco is simultaneously fed from both chambers by a common feeding device to form a metered flow from which the filler rod is ultimately formed. The level of tobacco in the narrow chamber is sensed and the operation of the common feeding device is controlled in response to sensed levels outside a predetermined range. If the sensed level is too high, then the tobacco is being fed too fast to the rod formation and the common feeding device then is slowed down, thereby slowing the tobacco feed rate, while, if the sensed level is too low, then the tobacco is being fed too slowly to the rod formation and the common feeding device then is speeded up, thereby speeding up the tobacco feed rate. |

A cigarette, having a tobacco rod consisting of at least two segments. The segment toward the filter end of the tobacco rod has a density at least 20% greater than the fire-end segment. The density differential may be combined with a nicotine differential, such that the fire-end segment has a higher nicotine content than does the filter-end segment. This configuration alters the nicotine delivery of the invention, providing a nicotine delivery either uniform during the last half of the cigarette or at levels reduced from those seen during the first few puffs. |

Disposable smoking devices disclosed in a variety of pipe, cigarette or cigar configurations, and designed to totally suppress the inhalation by the user of the toxic substances contained in tobacco smoke. This goal is achieved by keeping the air-intake channel separated from the combustion chamber by a fire-resistant, but heat-conductive wall and by depositing on the channel-side of this wall nicotine and other tobacco-simulating substances in a volatile or sublimable form whose vapors only are inhaled; thus giving the user the same sensations as a common pipe, cigar or cigarette, but free of the deleterious effects inherent to the absorption of tobacco smoke.The air intake channel may be located either in the center of the combustion chamber or along its periphery. |

Smoking articles comprising a high density, relatively low porosity coherent mass of combustible tobacco-containing material having at least one passage extending therethrough are disclosed. In a preferred embodiment the smoking article is a cylinder having at least one passage axially therethrough. The smoking article may further comprise a plug of ignitable material in passage blocking position at one end of the passage, said plug being such as to permit puff induced air flow therethrough. At least one additional plug may be similarly disposed at the opposite end of the passage or at an intermediate point in the passage. By adjusting the density, the surface area and/or the porosity of the mass available for combustion, the per puff delivery of tar by the smoking article upon combustion may be controlled. |

A method of making smoking articles wherein a combustible tobacco material is mixed with one or more other ingredients including a liquid, the mixture being subjected to further processing to produce a shaped coherent mass having a through passage. Shaping is effected by application of pressure to the mixture to form the coherent mass, and is followed by drying of same, the mixture composition being selected and the shaping pressure and drying being controlled to impart to the shaped mass a porosity and density such as to substantially occlude gas flow therethrough and a porosity sufficient to support combustion of the shaped mass when ignited. |

Disclosed is a smokable tobacco product comprised of a tobacco portion consisting essentially of tobacco particles having a mean ratio of area to perimeter squared of at least about 0.049 and a short dimension not in excess of 0.5 inch wherein the particles are of a substantially normal particle size distribution. By forming a smokable tobacco product of such particles, the lattice structure is highly resilient, enabling product formation at lower than normal weights while retaining similar firmness, end stability and burn properties as conventional cigarettes. |
