  • Such spreaders and methods are used in the tobacco processing industry to feed an extruder-enriched product stream of fibrous material, which may consist of tobacco fibers, filter material fibers or blends of the aforementioned fibers, to a stranding machine by separating, screening and then uniformizing the fiber material or any strand-forming Saugstrang makeuper is supplied. So that the additives are not rediscovered during sifting, the additives are fed into the product stream or into the portion of the fiber material to be processed behind the transverse sifter device.
  • fibrous material which may consist of tobacco fibers, filter material fibers or blends of the aforementioned fibers
  • the product flow extends transversely to the conveying direction F over a width B, so that on the output side of the distributor device at the or each suction strand conveyor a strand with increasing in the transport direction T of the or each Saugstrang disposeers thickness builds up by a layered layering.
  • the entire product flow is effectively divided into two sub-streams. More specifically, air flow is created by the compressed air applied by the classifier nozzle unit, which causes the fiber material to divide into a portion to be processed and an unprocessable portion.
  • portions not suitable for processing for example, ribs, foreign matter, or the like, are sorted out by sinking down into the drainage channel or the like. Only the lighter tobacco fibers, filter fibers or the like, which make up the portion suitable for processing, are guided by the air flow into the classifier channel.
  • This proportion suitable for processing is enriched by additives.
  • pourable additives are exemplified granules, tobacco components or the like but also excluded in sifting and then - sometimes called after a processing / comminution - recycled fiber residues.

  • the distributor device described therein has for supplying the additives to a delivery line, by means of which the additives, here recirculated tobacco ribs, are passed directly into the rolling space.
  • the known distribution devices and methods for feeding a stranding machine, in particular with existing from tobacco and enriched by additives fiber material have the disadvantage that the additives reach the tobacco mat and reflected from there and are not mixed correctly.
  • the invention is thus based on the object to provide a simple distributor device, by means of which an optimized supply of additives in the product stream formed from to be processed portions of the fiber material is ensured for an individual and high quality strand design.
  • the object continues to be to propose a corresponding method.
  • the feed device for feeding the additives comprises at least one feed channel, which opens directly into the classifier channel.
  • This embodiment of the invention causes the additives to be processed after sifting and before entering the acceleration section with the Mix the proportion of fiber material so that a uniform and individually controllable distribution in the strand is achieved.
  • the additives are given by the inventive design via an injector in the sighted and already accelerated tobacco stream (formed from the portion of the fiber material to be processed). This results in a laterally sharply delimited product stream, which allows an accurate positioning of the additives in the strand. This sharp limitation also prevents loading of the excess, which is separated / trimmed from the bed formed on the suction belt to form the actual strand.
  • a particularly preferred development of the invention is characterized in that the mouth region of each feed channel is arranged in the classifier channel in the conveying direction F of the portion of the fiber material to be processed behind the classifier nozzle unit and the or each feed channel projects at least partially into the classifier channel with its mouth region such that the cross-section Q 1 of the classifier channel is narrowed in the region in which the supply channel opens into the classifier channel.
  • This restriction leads to an increase in the flow rate, so that the energy for entrainment of the additives is increased from the feed channel.
  • the "injector effect" produced by the compressed air or flow velocity is intensified by the constriction in the region of the entry of the additives into the classifier channel.
  • the acceleration section is formed as a rolling room with nozzle cavity, wherein the nozzle cavity in the conveying direction F of the fiber material adjoins and in extension of the classifier channel.
  • This embodiment with a direct transition between the classifier channel and the nozzle channel is particularly suitable for achieving a mixing of additives with the portion of the fiber material suitable for processing.
  • the classifier nozzle unit comprises a caution nozzle, which is arranged in the region of the deflection of the not yet sighted fiber material from the channel into the classifier channel, such that the portion of the fiber material to be processed is transported through the classifier channel in the direction of the acceleration section while the unprocessed portion of the fiber material falls down into the region of recycle and / or discharge.
  • a particularly advantageous embodiment is characterized in that a supply channel is guided through the rolling space and opens into the classifier channel from above, through the intersection of the rolling space boundary separating the rolling space from the classifier channel.
  • a preferred development is characterized in that a feed channel from the opposite side of the rolling chamber of the classifier channel opens under the penetration of the classifier channel wall from below into the classifier channel.
  • each feed channel opening into the sifter channel is curved in its mouth region, such that the mouth opening of the feed channel is directed within the sifter channel in the direction of the rolling space. Due to the fact that the additives already have a predetermined direction when entering the classifier channel, namely in the conveying direction, the "injector effect" can be used particularly effectively, since the additives have to be taken along / entrained almost without further deflection. As a result, the additives are introduced at high speed into the rolling space.
  • a particularly expedient embodiment is characterized in that in the region of the nozzle well, a further feed channel is formed, which opens directly into the rolling space.
  • a further feed channel is formed, which opens directly into the rolling space.

That is, the supply channel is (substantially) narrower than the distributor device width or the width B of the conveyor line and thus allows a defined addition of the additives in the strand.
  • the width of the feed or the mouth region determines the distribution of the additives in the strand and thus in the products formed from the strand (for example the cigarettes). This ensures a targeted supply of additives to a defined section / region of the strand.

  • the defined section / area into which the additives are to be positioned within the strand can be varied.
  • the object is also achieved by a method with the steps mentioned above in that the additives are fed via at least one feed channel directly into the classifier channel, so that the additives mix with the portion of the fiber material to be processed before the acceleration section.
