Definitions

  • the invention relates to a device for producing a rod in the tobacco processing industry, comprising a rod-making 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 configured to provide a material rod made of a tobacco material, and wherein the rod-forming unit is configured to wrap the material rod that can be provided by the rod-content supply unit in a format unit with a wrapping strip. Furthermore, the invention relates to a method for producing a rod in the tobacco processing industry using such a device. Finally, the invention relates to a rod-shaped article produced from a rod in 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 include cigarettes, cigars or generally tobacco sticks, filters, or filter segments.
  • articles from the tobacco processing industry that have a rod-shaped shape but do not require a combustion process during consumption should also be considered rod-shaped articles.
  • An example of such rod-shaped articles from the tobacco processing industry are so-called HnB articles (heat-not-burn articles). These are products from the tobacco processing industry that are heated but not burned during consumption. When an HnB article is consumed, vapor is generated by the transfer of heat, for example from an electrically operated heat source, to an aerosol-forming substrate contained in the HnB article. This vapor is intended for consumption and contains flavorings and other ingredients.
  • a tobacco-containing substance is often used as the aerosol-forming substrate, but unlike conventional smoking products, it is not burned. In many cases, a film made of reconstituted tobacco material (recon film) is used as the tobacco-containing substance.
  • Aroma-forming additives include, for example, flavored threads or strips that are integrated into the tobacco rod.
  • GB 2 260 887 A A method and device are known in which the tobacco material fed to the suction rod conveyor is provided with an additive.
  • the additive can be introduced in the form of a continuous or discontinuous element. It is also possible to spray the additive.
  • the additional element can be essentially rigid or inflexible, for example in the form of a rod, tube, or cylinder.
  • DE 36 02 846 A1 A smoking article is known, for example a cigarette, which comprises a core element and a wrapping material.
  • EP 2 219 481 A1 is a filter for a rod-shaped article in the tobacco processing industry.
  • a wrapping paper of the filter plug is attached to the periphery of the filter material with an adhesive, which contains a flavoring agent.
  • WO 2020/211294 A1 is a product used in the tobacco processing industry that comprises a folded sheet of flavored material into which a thread of paper-based gel is inserted.
  • the device comprises a separating device with which a flat web of reconstituted tobacco material is separated into a plurality of strips.
  • the separating device has a first roller and a second roller cooperating with the first roller, the lateral surfaces of the rollers having grooves and elevations that alternate in the axial direction and are closed in the circumferential direction.
  • the elevations of the first roller engage in the grooves of the second roller, and the elevations of the second roller engage in the grooves of the first roller.
  • the separating device configured in this way is designed to separate directly adjacent strips from one another along a predetermined separating line in the active region by overstretching the flat web transversely to the separating line to such an extent that it tears apart along the separating line.
  • the device further comprises a rod-forming unit that is designed to form a rod of reconstituted tobacco material from the plurality of strips.
  • the device comprises a separating device designed to separate a flat web into a plurality of strips.
  • a first width of a first elevation of the first or second roller and a first associated width of a first groove of the second or first roller which interacts with this first elevation are greater or smaller than a width of a second elevation of the first or second roller and a second associated width of a second groove of the second or first roller which interacts with the second elevation.
  • the device makes it possible to easily and flexibly vary the amount of strip material added to the tobacco material.
  • the strip material is obtained by cutting the flat web longitudinally.
  • the flat web can be made of any material, but according to the invention, it is a flavored material.
  • the flat web can be paper-like or made of a tobacco material.
  • the material of the flat web can be mixed with one or more flavors, ingredients, and/or active ingredients, so that the aroma of the rod-shaped articles produced from the material strand can be adjusted by adding more or less mass in the form of the flat web to the material strand.
  • the mass of the supplied strip material can be easily varied via the width of the flat web fed from the supply device to the separating device.
  • a narrower flat web means less strip material
  • a wider flat web means more material added to the tobacco rods in the form of strips.
  • Another variation option is the width of the individual strips. Narrow strips have a high surface-to-volume ratio. Accordingly, ingredients and active ingredients, such as flavors, will quickly evaporate from these strips upon heating and pass into the consumable airstream. Wider strips, on the other hand, have a smaller and, in this sense, less favorable surface-to-volume ratio, and the transfer of flavors and active ingredients will occur more slowly in this case.
  • variations can be easily implemented.
  • the device according to the invention advantageously allows for off-center positioning of the strips.
  • the positioning viewed in the cross-section of the tobacco rod
  • the positioning of, for example, flavor-enriched threads or the like in the tobacco rod is not critical. This is not necessarily the case with HnB articles.
  • classic articles from the tobacco processing industry burn or smolder during consumption and, as a result of the heat development, the aroma and ingredients are transferred into the smoke stream intended for consumption, HnB articles are heated by an electrically operated heating element and not burned.
  • the heat is sometimes introduced into the tobacco rod of the rod-shaped article from the outside, i.e. via the outer surface of the article.
  • the heat is introduced by a heating element inserted centrally into the tobacco rod.
  • the strips which are made, for example, from a flat part coated with flavorings, are not located centrally and, in this sense, off-center in the tobacco rod. If the heat used to heat the material of the tobacco rod is coupled via the outer surface, strips arranged centrally in the tobacco rod are only heated quite late during consumption and therefore only release their active ingredients towards the end of the consumption period. If, on the other hand, the strips are arranged closer to the outer surface, they are heated earlier during the consumption period and therefore also release their active ingredients and ingredients earlier.
  • the material of the tobacco rod is heated via a heating element inserted centrally in the rod, strips arranged centrally in the tobacco rod could hinder this process and possibly lead to damage to the heating element.
  • the strips are arranged closer to the periphery (again viewed in the cross-section of the tobacco rod).

This ensures that the strips are not placed directly against the outer surface (lateral surface) of the rod-shaped article.

  • the distance of the strips from an outer surface of the rod-shaped article can be adjusted. If this position is selected so that a larger amount of fluffed tobacco material has already accumulated on the suction belt and the strips are only fed into the process at this position, the strips are positioned further towards the center of the rod-shaped article. If, on the other hand, the position is selected upstream of the previously described position, a smaller amount of fluffable tobacco material has already accumulated on the suction belt and the strips are positioned further towards the periphery, i.e. closer to the outer surface, within the rod-shaped article.
