Definitions

  • the invention relates to a method of processing a wrapping material strip for rod-shaped articles of the tobacco-processing industry, wherein the wrapping material strip has zones in which the oxygen permeability is reduced compared to the other regions of the wrapping material strip.
  • the invention further relates to an apparatus of the tobacco processing industry for processing such a wrapping material strip for rod-shaped articles of the tobacco-processing industry.
  • a wrapping material or cigarette paper is used in cigarette production, on which at intervals of a few centimeters transverse strips are applied, for example, 5 mm to 7 mm wide and less permeable to oxygen.
  • Such cigarette paper is called LIP cigarette paper from the English term "Low Ignition Propensity”.
  • the tucks have the property of changing the paper structure to reduce the oxygen permeability compared to the cigarette paper otherwise used.
  • the horizontal stripes can be applied during papermaking or by processing the finished paper. To this is on the EP 1 417 899 B1 referenced, from which also materials for the horizontal stripes are removable.
  • the aim of processing the usual cigarette paper is to produce densified zones which have a lower oxygen permeability, so that the cigarettes with this paper on a substrate under standard conditions are likely to extinguish.
  • This problem is solved by a method for processing a A wrapping material strip for rod-shaped articles of the tobacco processing industry, wherein the wrapping material strip has zones in which the oxygen permeability is reduced compared to other regions of the wrapping material strip outside the zones, wherein an edge region of the wrapping material strip on the rod manufacturing industry of the tobacco processing industry is an adhesive is applied, is mechanically changed, wherein the mechanical modification is an embossing.
  • a mechanical change of the edge region of the wrapping material strip which serves for bonding, ensures that the applied adhesive from the paper at least in the zones in which the oxygen permeability is reduced at least before processing, because there are corresponding materials were applied, the adhesive is well absorbed. It has been recognized that in the area of the LIP strips, that is to say where the densified zones are provided in the wrapping material strip, there is a poor glue or adhesive absorption of the wrapping material strip.
  • the mechanical change of the paper by embossing improves the wetting and the absorbency of the paper increases, so that corresponding adhesive can be resumed.
  • the bond strength when closing the wrapping material strip for example, the lining, the filter or the cigarette paper is improved. By improving the bond strength, the production speed can also be increased since the bond seam is less likely to reopen. Accordingly, the setting time can be reduced.
  • the mechanical change preferably takes place before application of adhesive.
  • the edge region is additionally processed abrasive, in particular by roughening or perforating. This can be done for example by grinding.
  • the abrasive machining can be done before and / or after stamping.
  • cigarette paper, filter paper and tipping paper which is present as a wrapping material strip in the production of cigarettes or filters, is relatively thin and can thus tear easily, the processing of the edge area must be carried out with care. In particular, it should be avoided to allow reinforced tension to act on the wrapping material strip.
  • material is removed from the edge region by the action of energy, in particular by laser beams.
  • Laser beams can be generated by a laser with sufficient power and energy density, such as an excimer laser, a CO 2 laser and / or a Nd-YAG laser, which then ablate material by ablation.
  • a pulsed laser may be used so that the laser beams strike the wrapping material strip at a time when the densified zones or zones in which the oxygen permeability is reduced compared to the other regions of the wrapping material strip are abraded in the edge region at least partially removed.
  • a synchronization with the wrapping material strip run can be made.
  • a sensor may be provided which measures the corresponding zones with reduced oxygen permeability and, depending on the speed of the wrapping material strip, a trigger signal is given to the laser.
  • the removed material is sucked off, so that the removed material is not or substantially no longer in the further processing process occurs.
  • the edge region is mechanically changed on a deflecting device of the wrapping material strip, in particular a deflection roller, on a straight guide, in the inlet region of a formatting device, in the format device and / or immediately before the application of adhesive.
  • the embossing of the edge region preferably takes place on a deflection device of the wrapping material strip, in particular a deflection roller, and / or on a straight path of the wrapping material strip.
