These are, for example, so-called HNB items (HNB for “Heat-Not-Burn”), which are also referred to as THP items (THP for “Tobacco Heated Product”). These items include tobacco-containing material that is heated for consumption. The aroma and ingredients of the tobacco are provided together with an aerosol-forming substance in an air stream intended for consumption.

  • a device is known with which a rod-shaped article can be produced in which aerosol-forming tobacco material is present in the form of a large number of strips.
  • THP articles Just as with conventional rod-shaped articles in the tobacco processing industry, it is also desirable for THP articles to provide their tobacco material with additives.
  • a device for producing a strand in the tobacco processing industry comprising a strand content provision unit which is set up to provide a strand of material to a strand forming unit arranged downstream, this device being developed in that the strand content provision unit comprises a web guide unit and a separating device, wherein the web guide unit is set up to hold a first tobacco material flat web, an additive flat web and a second tab.
  • the separating device To assemble the baking material flat web into a common multi-layer flat web, in which the additive flat web is embedded between the first and the second tobacco material flat web, and to feed the multi-layer flat web to the separating device, the separating device being set up to separate the multi-layer flat web into a plurality of multi-layer longitudinal strips and to provide this plurality of multi-layer longitudinal strips as a strand of material for the strand forming unit.

  • the strand of material includes a plurality of longitudinal strips, both made of tobacco material and additive.
  • Devices in which parallel running material strands or parallel running material webs cut into strips are provided are more susceptible to failure than the device according to aspects of the invention. For a disruption to the overall process, it is sufficient if a disruption occurs in just one of the material strands or cut material webs, for example a strip break. Reducing the number of parallel processes to a single process already improves the reliability of the overall process.
  • the additive flat sheet that Has additive and which will also be referred to below as additional material is less tensile or tear-resistant than the tobacco material.
  • the flat web made of additional material is more susceptible to a potential strip tear than the tobacco material flat web itself.

  • the arrangement of the additive flat web between the two tobacco material flat webs is also advantageous with regard to a splicing process of the additive flat web.
  • a splicing process occurs when an outgoing additive sheet is connected to a new additive sheet at a splice point.
  • the splice inevitably weakens the material of the additive flat sheet. Therefore, the risk of a strip breaking off or the entire strand breaking off in the area of the splice point is particularly high.
  • a partial tear of the strips of the additive flat sheet in the area of the splice can be tolerated.
  • the torn individual strips of the additive flat web are taken along in the sandwich structure by the tobacco material flat web located on both sides, for example above and below, or the strips made from these.
  • the additive flat web is more adhesive, especially with respect to the separating device, than the tobacco material flat web. If the separating device comes into direct interaction with the additive flat sheet, this can lead to the separating device sticking. This is advantageously avoided because the additive flat web is embedded between the tobacco material flat webs. As a result, the additive sheet does not come into direct contact with the separator to the same extent as if the additive sheet itself were cut or, for example, in a double layer structure on the top or bottom of a tobacco material sheet. This also represents a significant process technology advantage.
  • a further advantage of the device according to aspects of the invention which lies less on the process side and more on the product side, can be seen in the fact that the additive flat web is in contact with the first and second tobacco material flat web over a large area, ie on both flat sides. It is thus possible for the tobacco material and the additive present in the additive flat web to be heated and consumed together. The flavors and ingredients contained in the tobacco material, together with the additives, pass into the air stream intended for consumption, since the tobacco material and the additive are more or less always at the same temperature.

  • the separation process carried out in the separating device often exerts slight pressure on the multi-layer structure, so that the tobacco material flat web and the additive flat web are at least slightly connected to one another.
  • This connection between the tobacco material and the additive also ensures that the Additive is present homogeneously distributed (particularly when viewed in cross section) in the strand and thus also in the rod-shaped article made from the strand.
  • the additive flat web and/or the additive and/or the additive layer and/or the additive longitudinal strip has glycerin and/or propylene glycol.
