  • a Methods and a device are created with which on procedural high loads of the substances can also be applied in a simple manner.
  • the dosing being carried out taking into account the filter production speed becomes. This ensures that, for example, per fiber length unit always the same amount of substance is applied.
  • the dosage is expediently carried out by a discontinuously micronized solid feeding reservoir in connection with a fine metering device, the gravimetric works and a twin screw for feeding the micronized solids to a pneumatically working conveyor line.
  • a discontinuously micronized solid feeding reservoir in connection with a fine metering device, the gravimetric works and a twin screw for feeding the micronized solids to a pneumatically working conveyor line.
  • micronized solid particles become pneumatic through a solid injector nozzle promoted so that they are carried away by the negative pressure generated in a tube. This largely prevents clumping.
  • the pneumatically conveyed solids / air flow is replaced by a Mixing zone directed.
  • the actual pollination takes place in a powder chamber, which is in the direction of the surface or fibrous filter material is open so as not to allow the passage of the filter material hinder.
  • Triacetin is applied to the filter material, either in front of or behind the Powder chamber.

  • the air gap for the entry of the filter material into the powder chamber can be adjusted and is set so that contactless transport of the filter material is guaranteed is, but the escape of dosed solids from the powder chamber is prevented.
  • the Charge state of the filter material can be influenced.
  • an ionizing rod can be arranged, which Stick electrode and counter electrode. Through this ionizing bar the surface of the filter material charged to the adhesion of the micronized solid particles to improve.
  • two nozzles can be provided in the powder chamber, which feed the micronized solid particles from below or from above.
  • the filter material dusted with the micronized solid particles is after the Leaving the powder chamber merged into a filter rod and in the usual Processed into a finished filter.
  • a fan is expediently connected to the outlet of the powder chamber Air and micronized solids through the powder chamber and possibly through a dedusting system connected to the powder chamber sucks.
  • the negative pressure present at the outlet of the powder chamber can be adjusted and allows the extraction of excess air from the pneumatic conveying of the Solids.
  • the vacuum in the powder chamber can be adjusted laterally flap attached in the powder chamber.
  • the negative pressure on the fan during production and Dosing phase kept constant to ensure an even, constant product application to the To ensure filter tow and to prevent dust from escaping from the powder chamber.
  • Filter tow 32 is schematically shown in the usual way as a spread, spanned web indicated drawing rollers 33 and a guide 35 of a device 36, in the triacetin is applied to the filter tow web.
  • the filter tow 32 In the running direction of the filter tow 32 behind the triacetin application 36, the filter tow 32 again passed over a drafting system 37 and then passes into the gap between two Ionizing rods 39, namely a stick electrode and a counter electrode, which by a charging generator 41 with spark current limitation with a negative charging voltage be supplied.
  • the web-shaped filter tow passes from the gap between the two metering rods 39 32 into an inlet slot 43 of a powder chamber 34 (see also FIG. 2), which in Running direction of the filter tow 32 is open in order not to allow the passage of the filter tow 32 hinder.
  • the size of the gap 43 for the entry of the filter tow 32 into the powder chamber 34 can perpendicular to the running direction of the filter tow 32 and is set so that a contactless transport of the filter tow 32 is guaranteed and the exit of fluidized solids from the powder chamber 34 is prevented.
  • the clamped filter tow 32 is to be explained Dusted with micronized solids or solid mixtures, as in Fig. 2 by the two nozzles 52 are indicated, which are above or below the web-shaped filter tow 32 are located.
  • the powder chamber 34 On the side opposite the inlet slot 43, the powder chamber 34 is with a Provided outlet slot 54, on which there is a standard for filter manufacture Injector nozzle 44 is mounted, in which the filter tow 32 moves together to form a rod and dust-laden air is extracted.
  • the filter rod thus produced, dusted with micronized solid particles, is from Wrapped the filter wrapping paper and cut it to the required filter rod length fed to a cigarette manufacturing machine in a subsequent production step where it is cut into pieces of appropriate length and connected to the tobacco strands is what creates finished filter cigarettes.
  • micronized solids and solid mixtures to be discribed.
  • It can be physiologically safe and sensory act interesting substances, in particular polycarboxylic acids or acid salts of Polycarboxylic acids such as citric acid, tartaric acid, succinic acid, malic acid, ascorbic acid as well as acidic esters of such organic polycarboxylic acids, mono-di-saccharides (e.g. Dextrose, cane sugar) and flavor-active substances (vanillin, menthol, etc.).
  • the finely ground, micronized pure solids or homogeneous solid mixtures have a maximum particle size of 50 ⁇ m and become one of the process size adapted storage vessel 12 discontinuously entered into a fine metering device 14, whose fill level is detected via minimum / maximum sensors. The minimum level the sensors respond, and solids are removed from the storage container 12 refilled. When the maximum level is reached, the refill switches off automatically.
  • the gravimetric fine metering device 14 guides the solids or solid mixtures via a twin screw 16 driven by an electric motor 15 into a Pneumatically operating conveyor section 17.
  • the fine metering device 14 is electrically connected to the Filter manufacturing machine coupled, i.e. the dosing quantity per filter rod is as Fixed value entered in electronics 19 for fine metering device 14.

  • the machine speed is with a Encoder 20 on the cutter head 22 of the filter manufacturing machine detects the endless filter train cut into individual filter rods.
  • the solid / air stream is passed through a mixing zone 18, which is formed by a pipe leading vertically downwards into the powder chamber 34.
  • transverse slot die 52 In the upper area of the powder chamber 34 there is a transverse slot die 52, in which the width of the nozzle slot is transverse to the direction of production, that is to the direction of travel of the filter tow 32, at least the tow width before or after the triacetin application 36 corresponds.
  • the distance between the nozzle 52 and the filter tow 32 can be freely adjusted, by moving the slot die 52 vertically up or down, as by the Arrow 54 is indicated.
  • FIG Variant Although a single nozzle 52 is generally sufficient in principle, there is also one in FIG Variant shown, in which a second slot die 52 below the filter tow 32nd is attached.
  • the solid / air flow coming from the pneumatic conveyor line is divided in front of the two nozzles, the division of this stream being freely adjustable.
  • the powder chamber 34 narrows to a suction tube 56, whose vacuum can be adjusted and the extraction of the excess air pneumatic conveying of the solids allowed.
  • the negative pressure in the powder chamber 34 can be by a side of the powder chamber attached flap 38 can be adjusted.
  • the dust-laden, extracted conveying air is supplied for cleaning a mobile dedusting system 40.
  • the negative pressure in the Dedusting system 40 or in the powder chamber 34 is connected by a downstream Fan 50 generated.
  • the negative pressure on the fan 50 is kept constant during the production and metering phase in order to ensure an even, constant product order to ensure the filter tow and to prevent dust from escaping from the powder chamber 34 to prevent.
