Abstract: A smoking article, such as a cigarette, comprises a lighting end and a mouth end. The smoking article possesses an aerosol-generation system that includes (i) a heat generation segment, and (ii) an aerosol-generating region or segment. A mouth end piece segment can be located at the mouth end of the smoking article. A segment of tobacco cut filler, gathered tobacco paper, or other type of flavor source material, can be positioned between the mouth end piece segment and the aerosol-generation segment. Optionally, segment composed of tobacco cut filler can be positioned so as to provide a lighting end segment. The smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the mouth end piece segment, the aerosol generation segment, at least a portion of the length of the heat generation segment, any segment located between the mouth end piece and aerosol generation segments, and at least a portion of the length of the optional lighting end segment. Alternatively, the smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the aerosol-generating segment, at least a portion of the length of the heat generation segment, at least a portion of any segment located downstream from the aerosol-generating segment, and at least a portion of the length of the optional lighting end segment, thereby forming a cigarette rod; and the cigarette rod is connected or attached to a filter element using a tipping type of material and arrangement.

Abstract: Filter rods for use in the manufacture of cigarette filter elements are provided, with each rod having a longitudinal axis and incorporating a generally longitudinally extending filter material and a generally longitudinally extending strand within that filter material. A filter making unit receives a continuous supply of a filter material, and forms the filter material into a gathered composite having a continuous cylindrical shape. A continuous supply of a strand (e.g., colored thread) is provided and is introduced into the filter material gathered composite in the tongue of the filter making unit. The filter material and continuous strand positioned therein are formed into a continuous rod having the strand material laterally positioned within that rod, and the continuous rod is subdivided at pre-determined longitudinal intervals to provide a plurality of rod portions.
