Definitions

  • the invention relates to an apparatus (device) for forming an endless rod from a sticky tobacco material.
  • Conventional cigarettes comprise a rod made of tobacco material (tobacco rod) with a wrapping made of cigarette paper.
  • a cylindrical filter (plug) made of cellulose acetate with a wrapping made of filter paper (plug wrap) is placed on one end of the tobacco rod.
  • the filter and edge area of the tobacco rod is wrapped by a wrapping made of tipping paper.
  • the tobacco material is made of natural leaf tobacco, in particular by conditioning, stemming/stripping, drying, mixing, saucing (casing), flavouring by spraying on flavouring substances (top flavouring) and cutting.
  • up to 25 % reconstituted tobacco or other tobacco substitute is mixed into the tobacco material produced in this manner.
  • Reconstituted tobacco is a pliant, homogeneous, paper-like sheet, which is produced in a process known from paper production of finely ground and rebundled raw tobacco or from clean fabrication waste also treated in this manner.
  • One disadvantage of the conventional cigarette is that hazardous substances are released as a result of the burning of the tobacco material at temperatures of 800° to 1100°C.
  • the smoking article "Eclipse” from R.J. Reynolds contains an internal heat source in the form of a piece of coal provided with air channels and containing an oxidation means and a capsule with aerosol-generating material. When drawing on a cigarette, the glowing piece of coal heats the sucked-in air to approx. 300°C and vaporizes the heated air aerosol from the capsule.
  • Such smoking articles which heat the tobacco rather than burn it, are described in the Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, R.J. Reynolds Tobacco Company Monograph (1988 ) and Inhalation Toxicology, 12:5, P. 1-58 (2000 ).
  • EP 1 993 388 B1 describes tobacco products and smoking articles (e.g. cigarettes), which do not release products of incomplete burning and pyrolysis products.
  • the smoking article has an end to be lit, downstream from this a mouth end and an aerosol-producing system.
  • the aerosol-producing system comprises a heat-generating segment and an aerosol-producing segment, which is arranged downstream from the heat-generating segment.
  • the heat-generating segment preferably comprises a short heat source, which contains a combustible, carbon-containing fuel element.
  • the aerosol-producing area comprises an aerosol-generating material, e.g. glycerine and flavour.
  • a mouthpiece, on which the smoker can draw, is arranged on the mouth end.
  • the mouthpiece is preferably a filter.
  • the heat source is in intimate contact with particles of cerium oxide and a metallic halide, which convert carbon monoxide into carbon dioxide.
  • a metallic halide which convert carbon monoxide into carbon dioxide.
  • EP 2 443 947 A1 describes another smoking article, which has a carbon-containing fuel element in an end to be lit, an aerosol-producing system arranged downstream from it and a filter arranged downstream from it.
  • the smoking articles with integrated chemical heat source have the disadvantage that their production is complex. Moreover, they can create carbon monoxide and other poisonous combustion products that smoker ingests. There is also the risk that the tobacco burns and the taste of the aerosol is negatively impacted.
  • the electronic system "IQOS” by Philip Morris consists of a pen-like heater and the "Marlboro Heat Sticks", which contain pulverized tobacco.
  • the Heat Sticks are inserted into the holder.
  • the tobacco is heated to a temperature of up to 350° in the holder.
  • the nicotine-containing gas thereby released should contain fewer toxic substances and is inhaled by the consumer.
  • the health risks of conventional cigarettes should hereby be reduced. Details on the system are specified in the following documents: WO 2013/178766 A1 describes an aerosol-producing article comprising an aerosol-generating material, which is supported via a support element on a spacer element, to which a filter connects. The entirety is wrapped with cigarette paper.
  • the aerosol-generating material comprises a rod formed from a first sheet of crimped tobacco material and a second sheet of another tobacco material wrapped in a wrapping material.
  • a blade-like heating element of a heater penetrates the aerosol-generating material and heats it with a temperature of e.g. approximately 375°C. Aerosols are hereby released, which condense within the spacer element and exit the filter into the mouth of the user.
  • Variants of the aerosol-generating article with a second sheet of a flavour not made of tobacco are described in WO2013/178767 A1 and with a second sheet of aluminum foil in WO 2013/178768 A1 .
  • WO 2013/190036 A1 describes another variant, in which the aerosol-generating substrate is to be created such that a heating element with a diameter between 40% and 70% of the diameter of the aerosol-generating substrate can penetrate without significant deformation of the article.
  • WO 2013/098405 describes a variant, in which a support element and behind it a condensation element are arranged in the direction of flow behind the aerosol-generating substrate.
  • WO 2013/098409 A1 and WO 2013/098410 A2 describe variants, which have a front plug in front of the aerosol-generating substrate.
  • WO 2011/076407 A1 and WO 2013/098395 A1 describe heaters for smoking articles, which have an electrically heated pin, which is inserted into the aerosol-generating material of the smoking article.
  • US 8,430,106 and WO 2014/048745 describe a heater for a smoking article, which have a thermally conductive pin, which is pressed into an aerosol-producing material of the smoking article. The pin is also heated outside the smoking article, for example inductively.
  • the heaters with a heated pin have the disadvantage that they only direct the heat into the aerosol-producing material locally, so that it is heated unevenly. Furthermore, there is a risk of the aerosol-producing material adhering to the pin.
  • WO 2014/048745 describes a heater for smoking articles, which has electrically conductive particles in a cup, into which one end of the smoking article is inserted.
  • the cup is heated inductively.
  • the disadvantage is the only local and thus uneven heating of the aerosol-producing material.
  • the cigarette paper impairs the heat transfer, which results in increased heat output. This is particularly pronounced for smoking articles from several segments, which are held together by several layers of cigarette paper.
  • WO 2014/048745 describes a variant, in which an inductive heater heats electrically conductive particles, which are embedded into the aerosol-producing material of the smoking article.
  • the disadvantage of this is the increased production effort through the embedding of electrically conductive particles in the aerosol-producing material.
  • EP 0 846 424 B1 describes a device for forming a continuous tobacco rod for the cigarette production with a suction rod conveyor, which is equipped with a revolving, continuous, porous tape, to which vacuum is supplied from the top and on whose underside tobacco fibres are conveyed along a tobacco channel.
