  • DE-OS 38 39 431 a device is proposed in DE-OS 38 39 431 in which cigarettes aligned approximately parallel to the direction of transport are fed by means of a conveyor belt wetted with water to a roller system which has at least one slotted roller provided with circumferential knife rings in order to cut open the cigarette paper.
  • DE 41 19 873 AI which goes back to the same applicant, it was recognized as disadvantageous that a careful and costly cleaning of the system and the tobacco obtained is necessary, since the use of water can result in moist tobacco nests that tend to mold.
  • moistening is therefore dispensed with and the dry cigarette tubes are burst open due to their weakening with specially designed knife disks.
  • the reject cigarettes are subjected to a mechanical release effect and then subjected to a sieving process in the released state, for which purpose a machine with rotor and stator disks having release segments and a vibrating conveyor trough with a sieve insert are used coupled directly one after the other. Dry mechanical loosening in turn results in a considerable amount of paper dust and small paper particles and the risk of damage to the tobacco to be recovered, all of which have a negative effect on the quality of the tobacco that is recovered.
  • DE 29 42 604 A1 discloses a wet steam treatment of the entire cigarette, which is then subsequently torn and / or produced in a toric blower. This subsequently requires a costly separation of tobacco and paper particles, the separation result being subject to technical and economic limits. It can also be seen from the above-mentioned document that a certain moisture value in the range from 14 to 15 percent by weight should be aimed for, on the one hand to make the cut tobacco more flexible for treatment and to avoid breakage of the tobacco and dust development and on the other hand to prevent mold and ramifications of the tobacco. However, when treating large quantities, these requirements can only be met on average, but not for partial quantities, and if at all, only with great effort. In addition, the disadvantages known from all other aforementioned publications also arise here.
  • the object of the invention is to provide a separating device for tobacco-filled cigarette tubes, with which both the dangers of too wet tobacco and the disadvantages of too dry cigarette paper are eliminated.

  • the dispensing devices deliver a force transmission medium, by means of which at least one pressure change is generated in the moistened area, which is thereby torn open.
  • the moistening results in a partial weakening of the cigarette tube or tube, so that only low tear forces are required which protect the tobacco inside.
  • Large loads of both the enclosed tobacco and the casing are avoided by not directly acting on the casing with physical bodies in order to tear it open, as with various squeezing, cutting, tearing and striking tools in the case of the known techniques. Rather, according to the invention, a medium is used which applies suitable forces in a suitable, gentle manner to the moistened area.
  • Such a medium such as compressed air or ultrasound according to preferred embodiments, can be metered and directed very easily and precisely, so that only a small area of the casing needs to be moistened only a little in order to be able to open the latter without problems.
  • a correspondingly small amount of fluid is not significant for mold formation and other problems that can arise from it.
  • the air flow can again be used to at least partially evaporate or blow away the amount of liquid used.
  • the corresponding humidity is sufficient to at least largely prevent dust formation, which is further favored by the precise local limitation of the treatment.
  • the invention is not limited to tobacco-filled cigarette tubes of finished cigarettes, but can also be used for uncut, paper-wrapped tobacco rods with the same advantages.
