Definitions

  • the invention relates to a method for producing a tubular tobacco product and a tubular tobacco product and an aerosol-forming stick and an aerosol-generating device.
  • tobacco rod made of tobacco material
  • cigarette paper On the end of the tobacco rod usually a cylindrical filter (in the form of a plug) made of e. g. cellulose acetate with a wrapping made of filter paper (in the form of a plug wrap) is placed.
  • the filter and an edging area of the tobacco rod is wrapped by wrapping made of a special paper, for example of a tipping paper.
  • the tobacco material is made of natural leaf tobacco.
  • the material can be pre-treated or further processed for example by conditioning, stemming/stripping, drying, mixing, saucing, flavouring by spraying on flavouring substances and cutting.
  • final products from tobacco so called byproducts are generated from previous processes such as the threshing line.
  • the by-product generated from previous processes such as the threshing line, primary production and make & pack, can be collected and used in the manufacture of a tobacco sheet very similar to that of natural leaves of tobacco. The sheet is then cut into strips for ease of blending with other tobacco types.
  • the tobacco based components may include the leaf lamina, cut and rolled stem, reconstituted sheet and expanded tobacco.
  • the tobaccos stored in bales are broken up, cut into specific dimensions, and combined with other blend components such as casing and top dressing, and adjustment of the moisture content.
  • American blend cigarettes contain the four types of tobacco mentioned above plus reconstituted or homogenized sheet tobacco. This is made from tobacco dust, fines and particles, and leaf ribs and stems.
  • Reconstituted tobacco or homogenized sheet tobacco is a paper-like sheet approaching the thickness of tobacco laminae. It is made from tobacco dust, fines, and particles, and from ribs and stems.
  • Various additives may be incorporated. In the past, most of these "tobacco byproducts" were wasted.
  • reconstituted tobacco is already an important material in the tobacco industry and the significance will increase in the near future.
  • Different types of reconstituted tobacco is so far known.
  • Three examples of reconstituted tobacco are paper-making recon, slurry recon and cast recon.
  • Slurry recon can also be denoted or named as a slurry reconstituted tobacco composition.
  • Such composition can comprise for example at least reconstituted tobacco and water or in addition further ingredients can be added during the mixing procedure.
  • the document GB 2 078 087 A discloses smoking articles containing tobacco and method of making such.
  • the smoking article comprises a coherent mass of combustible tobacco-containing material having at least one passage extending through it between two spaced openings in the surface of the mass, the tobacco mass having such porosity as to support combustion when ignited and such density and porosity as to substantially occlude gas flow there through.
  • the article preferably has at least one air-permeable plug of readily ignitable material blocking the passage at one or both ends.
  • the tobacco-containing mass may include non-tobacco filler particles, such as carbon or clays, and the plug may contain a flavorant.
  • the articles may be made by shaping a mixture of combustible tobacco material with a volatile liquid, for example a mixture of water and ethanol, under pressure into a discrete coherent mass, preferably by extrusion, forming a passage through the mass, and drying the mass to a porosity and density such as to substantially occlude gas flow there through but to support combustion when ignited.
  • a method for producing a tubular tobacco product which comprises the steps of providing at least one mold device adapted to form a tubular product with a hollow bore extending along the longitudinal axis of the tubular tobacco product, casting slurry reconstituted tobacco composition into the at least one mold device, and removing the tubular tobacco product from the at least one mold device.

  • the rod is formed of tobacco material and/or other cellulosic or pyrolized bone material, together with a binder and preferably an organic or inorganic salt.
  • the materials are mixed in an aqueous or mixed aqueous/nonaqueous solution and then cast, extruded, or molded into the hollow rod shape.
  • the rod is either surrounded by leaf tobacco and wrapped in cigarette paper, or is wrapped directly with cigarette paper, and combined with a filter to form the smokeable article.
