Definitions

  • the invention relates to a device for producing a rod in the tobacco processing industry, comprising a rod machine with a rod content supply unit and a rod-shaping unit arranged downstream of the rod content supply unit, wherein the rod content supply unit is set up to provide a material strand made of tobacco material, and wherein the rod-shaping unit is set up to wrap the strand of material that can be provided by the strand content supply unit in a format unit with a wrapping strip. Furthermore, the invention relates to a method for producing a rod of the tobacco-processing industry with such a device. Finally, the invention relates to a rod-shaped article made from a strand of the tobacco processing industry and the use of said device for carrying out said method.
  • Rod-shaped articles of the tobacco processing industry are well known. These are, for example, cigarettes and cigars or generally around tobacco rods, filters or filter segments. In addition to these classic rod-shaped articles, such articles should also be regarded as rod-shaped articles of the tobacco processing industry which have a rod-shaped shape but which do not require a combustion process when consumed. An example of such a rod-shaped article
  • HnB articles heat-not-burn articles
  • This is a product of the tobacco processing industry, which is heated when consumed but not burned.
  • vapor is generated by the transfer of heat, for example from an electrically powered heat source, to an aerosol-forming substrate present in the HnB article.
  • This vapor is intended for consumption and contains flavoring and ingredients.
  • a substance containing tobacco is often used as the aerosol-forming substrate, which, unlike conventional smoking products, is not burned.
  • a sheet of reconstituted tobacco material is used as the tobacco-containing substance.
  • Flavor-forming additives are, for example, flavored threads or strips that are integrated into the tobacco rod.
  • GB 2 260 887 A discloses a method and a device in which the tobacco material fed to the suction rod conveyor is provided with additives.
  • the additive can be introduced in the form of a continuous or discontinuous element. It is also envisaged to spray on the additive.
  • the attachment may be substantially rigid or inflexible, for example in the form of a rod, tube or cylinder.
  • DE 36 02 846 A1 discloses a smoking article, for example a cigarette, which comprises a core element and a wrapping material.
  • a sheet of outer wrapping material, a stream of smoking material and a preformed rod forming the core element are fed to the format of a cigarette making machine.
  • the strand, which forms the core element is manufactured in another strand-making machine.
  • a filter for a rod-shaped article in the tobacco processing industry is known from EP 2 219 481 A1.
  • a wrapping paper of the filter plug is fixed on the periphery of the filter material with an adhesive, the adhesive containing a flavoring.
  • an article of the tobacco industry is known, which comprises a folded web of an aromatic material. A thread made of paper-based gel is inserted into this.
  • a device for producing a rod of the tobacco processing industry comprising a rod machine with a rod content supply unit and a rod forming unit arranged downstream of the rod content supply unit, wherein the rod content supply unit is set up to provide a material rod of a tobacco material, and wherein the strand-shaping unit is set up to wrap the strand of material that can be provided by the strand content supply unit in a format unit with a wrapping strip, the device being further developed by a supply device, a separating device and a feeding device, the supply device being set up to form a flat web, in particular a flat web mixed with an aroma, and to feed it to the separating device arranged downstream, the separating device being used for this purpose is erected to separate the flat web into a large number of strips and the feeding device is configured to add the plurality of strips to the strand of material.
  • the strip material is obtained by longitudinally cutting the flat web.
  • the flat web can be made of any material, but in particular it is a special flavored material.
  • the flat sheet may be paper-like or made from a tobacco material.
  • the material of the flat web can be mixed with one or more aromas, ingredients and/or active ingredients, so that a more or less large addition of mass in the form of the flat web in the material strand imparts an aroma to the rod-shaped articles of the tobacco processing industry made from the material strand can be adjusted.
  • the mass of the supplied strip material can easily be varied over the width of the flat web supplied from the supply device to the separating device.
  • a narrower flat web means less strip material
  • a wider flat web means more material that is added to the tobacco rods in the form of strips. Another possible variation is the width of the individual strips.
  • Narrow strips have a large surface area to volume ratio. Accordingly, ingredients and active ingredients, such as aromas, will quickly evaporate from these strips when heated and pass into the consumable air flow. Broader strips, on the other hand, have a smaller and, in this sense, less favorable surface
  • the device according to the invention position the strips off-centre.
  • the positioning tion (viewed in cross section of the tobacco rod) of, for example, ge flavored threads or the like in the tobacco rod uncritical.
  • HnB articles While classic items from the tobacco processing industry burn or burn up when consumed and, as a result of the heat development, the flavorings and ingredients are transferred to the flow of smoke intended for consumption, the HnB item is heated by an electrically operated heating element, for example, and not burned.
  • the heat input into the tobacco rod of the rod-shaped article occurs in some cases from the outside, ie via the lateral surface of the article.
  • the heat is introduced by a heating element inserted centrally into the tobacco rod.
  • the strips which are produced, for example, from a flat part provided with aromatic substances, are not located centrally and in this sense are off-center in the tobacco rod. If the heat used to heat the material of the tobacco rod is coupled in via the lateral surface, strips arranged centrally in the tobacco rod are only heated quite late during consumption, i.e. they only release their active ingredients and ingredients towards the end of the period in which consumption takes place away.
  • the strips are arranged closer to the lateral surface, they are heated earlier during the period of consumption and correspondingly release their active substances and ingredients earlier. If the material of the tobacco rod is heated via a heating element that is guided centrally in the latter, stripes present centrally in the tobacco rod could impede this process and possibly lead to damage to the heating element. It is also advantageous for such a device if the strips are arranged closer to the periphery (again viewed in the cross section of the tobacco rod).
  • the device can be obtained without major conversion measures from a conventional device in which no strips cut from a flat web are introduced into the tobacco rod.
  • a conventional machine can be converted into the device according to the invention by only minor conversion measures be rebuilt.
  • the flat web can also be reconstituted tobacco material (Recon).
  • the reconstituted tobacco material may be flavored tobacco material. It can also, optionally also additionally, be tobacco material which contains additional active substances.
  • the reconstituted tobacco material can be produced either by the paper process or by the slurry process.
  • a flat part that is not necessarily reconstituted tobacco material is generally suitable as the flat web. This flat part can be provided with aromatic and/or active substances.

  • the tobacco material can also be small tobacco parts, in particular those made from reconstituted tobacco material.
  • the device is further developed in that the strips are attached to the tobacco material that can be sprayed in a can be fed to the stacking area of the suction belt of the strand content provision unit. Feeding the strips to the flurried tobacco material in the heaping area of the suction belt ensures that there is a minimal amount of tobacco material between the suction belt and the strips. This results in the strips not being placed directly on the outer surface (mantle surface) of the rod-shaped article.
  • the device is further developed in that the strips can be fed to the tobacco material that can be sprayed on at a position within the heaping area, this position having a predetermined distance from an upstream beginning of the heaping area.
  • the distance between the strips and an outer lateral surface of the rod-shaped article can be adjusted by varying the position at which the strips are fed to the tobacco material that has been sprayed. If this position is selected so that a large amount of tobacco material has already accumulated on the suction belt and the strips are only fed into the process at this position, the strips in the rod-shaped article are positioned further towards the center. If, on the other hand, the position is selected upstream of the position described above, only a small amount of tobacco material that can be sprayed up has accumulated on the suction belt and the strips are further in the direction of the periphery, i.e. closer to the outer lateral surface, within the rod-shaped article po positioned.
