  • Patent number: 7967018
    Abstract: A cigarette-making method is provided, comprising forming an elongate tobacco rod having a non-circular cross-sectional shape and opposed ends, by circumscribing a tobacco charge with a wrapping material. A filter element is formed having opposed ends and a non-circular cross-sectional shape corresponding to the cross-sectional shape of the tobacco rod, by circumscribing a filter material with a plug wrap material. One end of the tobacco rod is axially aligned and abutted with one end of the filter element, and a tipping material is applied about the tobacco rod and the filter element, wherein the tipping material extends across the abutting ends thereof, so as to join the tobacco rod with the filter element and form a cigarette having a non-circular cross-sectional shape along a length thereof. Associated apparatuses and methods are also provided.

  • Patent number: H1271
    Abstract: The present invention relates to a plurality of manufactured cigarettes adapted to be arranged in a packaged configuration thereof. Each of the cigarettes include a rod of smokable material contained in a circumscribing paper wrapper (i.e., a "smokable rod"). Each of the smokable rods have a plurality of substantially flat sides and have at least one crease longitudinally extending substantially along the total length thereof. Preferably, each of the smokable rods includes a pair of creases longitudinally extending substantially along the length thereof to define one of the flat sides. The present invention also relates to a method of manufacturing cigarettes adapted to be arranged in a packaged configuration. The method includes providing a plurality of cigarettes including a smokable rod having a substantially circular or oval cross-section, and applying a compressive pressure to the smokable rods to provide a plurality of flat sides and at least one crease in the smokable rod.
