Definitions

  • the invention relates to a device for forming a tobacco rod. Furthermore, the invention relates to a machine of the tobacco-processing industry, in particular a cigarette rod machine, with the device for forming a tobacco rod. Finally, the invention relates to a method for forming a tobacco rod.
  • an endless tobacco rod is formed from loose tobacco. It is continuously wrapped with an endless strip of cigarette paper. The thus formed endless cigarette rod is cut in individual cigarettes. On the front end and if applicable on the rear end, cigarettes have a somewhat higher tobacco density so that tobacco fibres do not fall out. The compacted areas are also called end-densing. Outside of the end-densing, the most even possible tobacco density is striven for. For this, local tobacco accumulations are designed in the endless tobacco rod at regular intervals and the height of the endless tobacco rod is trimmed.
  • the endless tobacco rod is cut in the areas of the local tobacco accumulations wherein cigarettes with a head fortification only on the front end are cut from the cigarette rod at the border of the local tobacco accumulation and cigarettes with end-densing on the front and back are cut off the cigarette rod between the two borders of the local tobacco accumulations.

  • the device has a pre-equalizer for equalizing the height of the tobacco rod being conveyed in that part of the tobacco rod is removed.
  • the device according to the invention has an apparatus for compacting the tobacco rod at periodic intervals and an equalizer that, in order to equalize the height of the tobacco rod that is compacted at regular intervals, removes additional tobacco from the tobacco rod.
  • the pre-equalizer has a revolving blade, which is positioned directly below the tobacco channel.
  • the pre-equalizer has two circular blades overlapping within the tobacco channel, which shear off the protruding tobacco fibres.
  • devices for forming a tobacco rod which, below a suction rod conveyor, have a pre-equalizer with two trimming disks and a bevelled wheel arranged below it for cutting off the tobacco. Behind it in the conveying direction, a rotating cam is arranged for compacting the tobacco rod at regular intervals. This is followed in the conveying direction by another equalizer with a pair of trimming disks and a bevelled wheel arranged below it for cutting off tobacco, so that it has overall the height of the compacted areas.
  • EP 0 645 098 Bl discloses an apparatus in a cigarette rod making machine for removing surplus tobacco from a tobacco rod moving in a tobacco channel in a suction rod conveyor.
  • the apparatus comprises two holding discs which rotate in opposite directions and are at least approximately in mutual contact by way of their periphery, roughly in the middle of the tobacco channel, at a distance from the suction rod conveyor corresponding to the intended rod height.

The areas of the tobacco rod that engage with the recesses or flattened portions of the trimming disks during passage through the trimming disks are not trimmed and not condensed.

  • the known trimming apparatuses generate smooth cut surfaces with sharp cut edges, which favour the release and the transfer of moisture from the tobacco fibres to the cigarette paper.
  • Cigarettes produced using the device according to the invention have a considerably reduced or no spot formation. This is due to the fact that the trimming apparatus does not cut the tobacco fibres in a sharp-edged manner but rather tears them off in an irregular manner. This is attributed to the fact that the tobacco fibres can be pulled slightly out of the tobacco rod when being hidden by the removal means since the insertion areas between the peripheries of the trimming disks are not yet held tightly like at the point of the greatest convergence of the trimming disks.
  • tobacco fibres are sharply cut by a rotating circular blade or other removal means, the cutting edge of which sweeps over the point of the greatest convergence of the trimming disks and not the insertion area in front of it.
  • the irregular tearing of the tobacco fibres apparently reduces the transfer of the moisture to the cigarette paper so that the formation of spots is greatly reduced or stopped entirely.
  • the cause is apparently a greatly reduced release of moisture at the irregular separation surfaces or respectively only a punctiform contact of small parts of the separation surfaces with the cigarette paper, which restricts at least greatly the transfer of moisture, in contrast to the surface contact of the smooth cut surfaces in the state of the art.
  • the device has a trimming apparatus arranged upstream in the conveying direction of the conveying section before the apparatus for forming the tobacco accumulations, wherein the upstream trimming apparatus has a pair of upstream, rotating trimming disks, the rotational axes of which are arranged on different sides of the conveying section, the peripheries of which approach each other within the conveying section and between which the discharging apparatus transports the endless tobacco rod and which has an removal means for excess tobacco with at least one upstream, rotating blade, which is arranged on the side of the upstream trimming disks facing away from the discharging apparatus, with the at least one upstream rotating blade sweeps over the upstream insertion area between the peripheries of the upstream trimming disks in front of the point of the greatest convergence of the upstream trimming disks in order to thereby separate the sections of the tobacco rod protruding from the trimming disks.
