Abstract: Apparatuses, systems, and methods employing ultrasonic bonding to form filter elements for smoking articles are provided. Ultrasonic bonding can be employed to bond the fibers of filter material defining bloomed tow. Use of a plasticizer may not be necessary. Further, filter materials such as polylactic acid, which may not be bonded via a plasticizer, may be employed. However, triacetin or other additional components may be employed to provide the filter element with a desirable sensory attribute in some embodiments. Ultrasonic bonding may be conducted by an ultrasonic bonder that includes an anvil defining a pattern thereon that is selected to define a desired degree of bonding, and thereby a resulting desired firmness and/or pressure drop associated with the filter element.

Abstract: A method is provided for manufacturing a filter of a filtered smoking article, where the filter material includes a fluid-releasing body. The method provides a fluid-resistant barrier between the filter material and plug wrap encompassing the filter material, where the barrier is applied as a hot melt adhesive. In other aspects, mechanisms for using the method are provided.

Abstract: A method is provided for manufacturing a smoking article from a wrapped tobacco rod and a filter material wrapped to form a filter plug. The method utilizes nozzle-applied cold glue adhesive rather than roller-applied adhesive applied to tipping material, which connects the tobacco rod to the filter plug. In other aspects, mechanisms for using the method are provided.

Abstract: A smoking article includes a smokable rod manufactured using a paper wrapping material having an additive material applied thereto as a pattern. The additive material is applied as coating formulation (e.g., an aqueous coating formulation) incorporating a film-forming agent such as alginate, starch, or another polymer. The wrapping material includes at least one coated region with a porosity of less than about 20 CORESTA and a diffusion capacity no greater than about 0.2 cm/sec, where the coated region is on a base sheet with a porosity of greater than about 120 CORESTA and a diffusion capacity of at least 1.7 cm/sec.

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.

Abstract: A smoking article, such as a cigarette, includes a lighting end and a mouth end. The lighting end is a longitudinally extending segment comprising smokable material that is intended to be lit and burned, and the resulting smoke generated by the burning of that smokable material is intended to be drawn into the mouth of the smoker through the mouth end of smoking article. A mouth end piece is located at the mouth end of the smoking article, and the mouth end piece allows the smoking article to be placed in the mouth of the smoker to be drawn upon. The smoking article further incorporates an aerosol-generation system that is located between the lighting end segment and the mouth end piece. The aerosol-generation system includes (i) a heat generation segment located adjacent to the lighting end segment, and (ii) an aerosol-generation region located between the heat generation segment and the mouth end piece. The aerosol-generation region incorporates an aerosol-forming material (e.g., glycerin and flavors).

Abstract: A new substrate for cigarettes includes an overwrapped rod of gathered cellulose-based paper having an outer diameter of from about 4 mm to about 8 mm; wherein the paper has a basis weight in the range of about 10 g/m.sup.2 to about 90 g/m.sup.2 ; and the paper can include up to about 50 weight percent of one or more burn retardant hydrated salts. The substrate typically comprises an overwrapped rod of a gathered web of a nonwoven cellulosic material, having a length of about 10 mm; wherein the dry unit weight of the substrate rod is from about 20 mg to about 120 mg; and wherein the web of cellulosic material is embossed or scored prior to gathering, thereby providing a substrate rod with a pressure drop of from about 2 to about 40 mm of H.sub.2 O, under FTC conditions.

Abstract: An apparatus for collecting samples of smoke components from predetermined segments of drawn smoke during a predetermined time interval is disclosed. The apparatus includes a smoking machine for drawing successive individual puffs of smoke from a cigarette and for providing a predetermined path of travel for drawn smoke. The particulate matter of the drawn smoke is collected on a filter pad positioned on a movable stage for providing relative movement between the filter pad and the path of travel of the drawn smoke. Advantageously, the filter pad is moved transversely relative to the path of travel of the drawn smoke. A method for collecting samples of smoke components of drawn smoke is also provided.

Abstract: An aerosol delivery article is capable of producing substantial quantities of smoke, both initially and over the useful lifetime of the product, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products or sidestream smoke. The article also delivers very low levels of carbon monoxide. The article is able of providing the user with the sensations and benefits of cigarette smoking without burning tobacco. The article includes a carbonaceous fuel element, an aerosol forming substance within a heat conductive container, an outer member surrounding the heat conductive container, and a mouthend piece. Upon draw on the mouthend piece air enters the peripheral region of the outer member and enters the heat conductive container. As the heat conductive container is in a heat exchange relationship with the fuel element, aerosol is thereby formed within the container and passed to the mouth of the user.
