Aerosol-Generating Article and Method for Producing an Aerosol-Generating Article
An aerosol-generating article includes a rod of aerosol-generating substrate, a mouthpiece including a plug of filtration material, a wrapper, and a tobacco-containing layer including tobacco and an aerosol-forming agent, wherein the rod is wrapped by the wrapper and by the tobacco-containing layer, and the tobacco-containing layer is positioned in contact with a surface of the wrapper. A method for producing an aerosol-generating article includes preparing a tobacco-containing slurry, depositing the slurry onto a first sheet to form a sheet coated with a tobacco-containing layer, attaching a paper sheet to the first sheet to form a wrapper before or after depositing the slurry onto the first sheet so that the paper sheet and the tobacco-containing layer are on opposing sides of the first sheet, and subsequently wrapping a rod of aerosol-generating substrate with the wrapper including the first sheet, so that the tobacco-containing layer is facing the rod.
LOW IGNITION PROPENSITY CIGARETTE PAPER AND MANUFACTURE THEREOF
A wrapper of a smoking article includes a base web and at least one transverse banded region. The banded region includes a first zone, a second zone and a third zone of add-on material. The second zone has about 25% to about 75% less add-on material than the first zone and the third zone. The banded region is about 5 mm to about 9 mm wide and the second zone is centrally located between the first zone and the third zone. The second zone includes a plurality of dots of the add-on material spaced from adjacent dots in the second zone by a distance greater than a distance between adjacent dots in the first zone and the third zone.
Apparatus and method for making a smoking article
An apparatus for making a smoking article, the smoking article having a rod of smoke able material (15) and a cylindrically wrapped layer of sheet material, comprises a holder (3) for holding sheet material, an embossing unit (8) configured to emboss sheet material drawn from the holder and an assembling station (14) for assembling the smoking article, configured to receive embossed sheet material from the embossing unit and to wrap the embossing sheet material at least partially around a part of the smoking article.

Coated plug wrap for a smoking article
The present invention is directed to a coated plug wrap for a smoking article. The coated plug wrap is comprised of a base paper and a coating. In accordance with the present disclosure, the base paper may be comprised of hardwood pulp fibers and optionally, softwood pulp fibers. The base paper may be coated with a coating material such as an acrylate, a styrene, a butadiene, a starch, a starch derivative, a cellulose derivative, an alginate, a polyvinyl alcohol, a polyvinyl acetate, a gelatin, a gum, or a combination thereof. In one embodiment, the coated plug wrap may be incorporated into a smoking article.
METHOD OF FORMING SMOKING ARTICLES WITH MOUTH END CAVITIES
A method of producing smoking articles, the method comprising a first step of providing a continuous array of first filter members (42), second filter segments (20) and tubular members (40). A tubular member (40) is provided between each pair of consecutive first filter members (42) and a second filter segment (20) is provided between each first filter member (42) and each tubular member (40). Each second filter segment (20) contains one or more breakable capsules, wherein each breakable capsule comprises an outer shell and an inner core containing an additive. The continuous array of first filter members (42), second filter segments (20) and tubular members (40) is then wrapped with a continuous sheet of plug wrap (44) to form a wrapped filter array, wherein the plug wrap (44) has a basis weight of less than 90 grams per square metre. The wrapped filter array is cut at an intermediate position along each first filter member (42) to provide multiple filter rods, each filter rod comprising two first filter segments (18), a tubular member (40) positioned between the first filter segments (18) and a second filter segment (20) provided between each first filter segment (18) and the tubular member (40). Next, a tobacco rod (12) is provided in axial alignment with and adjacent to each first filter segment (18) of one of the filter rods, and the filter rod and a portion of each tobacco rod (12) are wrapped in a tipping wrapper (50). Finally, the tipping wrapper (50) and the filter rod are cut at an intermediate position along the length of the tubular member (40) to form multiple smoking articles (10), each smoking article (10) comprising a tobacco rod (12) connected to a filter (14), wherein each filter (14) comprises a first filter segment (18) downstream of the tobacco rod (12), a second filter segment (20) downstream of the first filter segment (18), and a hollow tube segment (22) positioned between the second filter segment (20) and the mouth end of the filter (14). The hollow tube segment (22) defines a cavity (24) at the mouth end of the filter (14).
CIGARETTE WRAPPER WITH PRINTED CATALYST
A wrapper for a smoking article includes a web; and a patterned deposit on at least a portion of one surface of the wrapper, wherein the patterned deposit comprises catalyst particles. The patterned deposit can include a nanoparticle catalyst that is capable of catalyzing the conversion of a constituent gas component in the mainstream and/or sidestream smoke of the smoking article. The constituent gas component can be carbon monoxide and/or nitric oxide and the catalyst particles can be iron oxide. Also provided is a smoking article comprising a tobacco rod having a wrapper formed around the tobacco rod, the wrapper including a patterned deposit on at least a portion of one surface of the wrapper. A method of making the wrapper and a method of making a smoking article utilizing the wrapper are also provided.
Low ignition propensity cigarette paper and manufacture thereof
A wrapper of a smoking article includes a base web and at least one transverse banded region. The banded region includes a first zone, a second zone and a third zone of add-on material. The second zone has about 25% to about 75% less add-on material than the first zone and the third zone. The banded region is about 5 mm to about 9 mm wide and the second zone is centrally located between the first zone and the third zone. The second zone includes a plurality of dots of the add-on material spaced from adjacent dots in the second zone by a distance greater than a distance between adjacent dots in the first zone and the third zone.
