  • the rib material falling out of zigzag sifter 22 can be blown with the aid of sifter air tapped from the circulating air system through a post-sifter, through which lighter tobacco particles still adhering to the ribs are transported back into the main air flow.
  • the tobacco ribs are then removed by a gate in a known manner, whereby reference is again made in particular to German Patent Application No. DE 101 54 807.9.
  • the sifted tobacco flow reaches tobacco/air separator 26 such that the separation of tobacco and air takes place by centrifugal force and the Coanda effect.
  • tobacco fibers are moved by centrifugal force along the outer geometry in the form of a curved outer side of separator 26 and the air spreads against the inner radius of the geometry in the form of a cylindrical surface of pipe body 48 due to the Coanda effect.
  • the final separation of air and tobacco takes place at separator edge 36 , so that the air separated from the tobacco is fed back to cross-flow blower 23 , which provides a uniform flow profile or a homogeneous speed distribution across the width (perpendicular to the drawing plane) of the distributor.
  • the tobacco separated in tobacco/air separator 26 is removed from the sifter system by bucket wheel gate 37 and, via impeller wheel 38 , portioned tobacco quantities arrive at ducts 40 and 40 ′ through distributor element 39 .
  • the position of distributor element 39 shown in FIG. 1 conveys the tobacco portion to duct 40 ′, i.e., on the right-hand side
  • the position of distributor element 39 shown as a dotted line in FIG. 1 conveys the tobacco portion to duct 40 , i.e., on the left-hand side.
  • ducts 40 and 40 ′ are arranged one behind the other and extend across an entire width of the arrangement, i.e., perpendicular to the drawing plane.
  • the tobacco is transferred in finely separated form from ducts 40 and 40 ′ by removal rolls 42 and 42 ′ and beater rolls 41 and 41 ′ via a guide surface to flow surfaces 44 and 44 ′, which are embodied or formed as nozzle troughs.
  • Corresponding air blast feeds 43 and 43 ′, as well as additional air blast feeds can be used to achieve an excellent separation of tobacco fibers.
  • Suction rod conveyors convey tobacco, which is not shown, in direction 91 , i.e., into the drawing plane of FIGS. 1, 2 and 3 .
  • FIG. 2 shows another embodiment of the arrangement according to the invention, in which no sifter is provided.
  • unsifted tobacco such as, e.g., kretek
  • Steep conveyor 17 conveys, in a known manner, tobacco into a drop duct 52 , to which impeller wheel 38 is connected for portioning the tobacco.
  • the portioned tobacco is fed to distributor element 39 to alternately convey the tobacco into the ducts 40 and 40 ′, which are arranged one behind the other.
  • vibration elements 60 and 60 ′ are provided in the lower area of ducts 40 and 40 ′ in order to uniformly release tobacco from ducts 40 and 40 ′.
  • the other elements correspond to those depicted in FIG. 1.
  • flow surfaces 44 and 44 ′ are divided, in a per se known manner into respective flow surfaces 441 and 442 and 441 ′ and 442 ′ so that four tobacco rods can be simultaneously produced.
  • This division of the tobacco flows from one flow surface to two flow surfaces is known from, e.g., German Patent No. DE 36 19 579 C2, German Patent Application No. DE 101 54 807.9, and European Patent Application No. EP 1 174 046 A2.
  • FIGS. 4 through 7 show different embodiments of distributor element 39 .
  • the tobacco fibers arriving in portions, e.g., from impeller wheel 38 , into drop duct 70 are fed to ducts 40 and 40 ′ via two flaps 71 and 71 ′.
  • Flaps 71 and 71 ′ are pivoted about rotating elements and are moved parallel with respect to one another, so that the movement direction is indicated by the double arrows.
  • a loose edge 72 is formed that renders possible a rotation about a rotational axis 73 in accordance with the double arrow, whereby, through a cut 74 , a separation of loose edge 72 from the walls bordering ducts 40 and 40 ′ is rendered possible.
  • FIG. 5 shows a distributor element formed by a transport belt 75 deflected around reels 76 and 76 ′.
  • Transport belt 75 is moved to and fro in order to correspondingly distribute the tobacco arriving from drop duct 70 into ducts 40 and 40 ′.
  • the distributor element according to FIG. 6 is a Y-distributor 78 that can be rotated from the depicted position, in which an opening to duct 40 is provided, into a position in which an opening to duct 40 ′ is provided.
  • a gate 35 provides a sealing to air and a portioning of tobacco.
  • a vibration element 77 or a reel 77 is utilized, which prevents tobacco fibers from sticking to an edge formed by the boundary walls of ducts 40 and 40 ′, so that clogging is counteracted at this point.
  • magnetic strips 90 and 90 ′ are attached in the distributor element in front of ducts 40 and 40 ′.
  • Magnetic strips 90 and 90 ′ are used to detach metallic particles from the tobacco and are normally arranged above the duct. Due to the smaller tobacco flow, in this exemplary embodiment, there is a better degree of detachment of magnetic particles.
  • a flap 71 is positioned to divide the tobacco flow.
  • FIG. 9 shows a further variant of the distributor element that includes a bucket wheel gate 37 and a closing element 82 and 82 ′.
  • duct 40 ′ In position 82 , duct 40 ′ is covered and, in position 82 ′, duct 40 is covered.
  • Closing element 82 or 82 ′ is arranged on a sliding strip (not shown), and a drive of bucket wheel gate 37 can be coupled to the sliding strip.
  • the drive can be a belt drive with an eccentric for the sliding strip.
  • FIGS. 10 and 11 show further variants of the distributor element, in which two flaps 71 or 71 ′ are utilized in accordance with the embodiment of FIG. 10, and one flap 71 is utilized in accordance with the embodiment of FIG. 11.
  • FIG. 12 a further variant of the distributor element is shown in FIG. 12, in which a belt gate 83 is composed of two conveyor belts 84 and 84 ′ and sliding elements 85 . Sliding elements 85 of each conveyor belt 84 and 84 ′ are moved in a direction of their respective arrows. By acting on tobacco falling in belt gate 83 with a force through sliding elements 85 , sliding elements 85 of conveyor belts 84 and 84 ′ thus convey tobacco alternately into ducts 40 and 40 ′. If a type of paddle 86 or 87 is used as sliding elements 85 , as shown in FIGS. 13 and 14, the distribution of the tobacco is more precise.
  • FIG. 15 shows a section of a further embodiment of the arrangement according to the invention, which is similar to the embodiment depicted in FIG. 3.
  • the tobacco from flow surfaces 44 and 44 ′ is distributed onto four suction rod conveyors (not shown) in rod assembly unit 51 via a bifurcation 88 or 88 ′ which are also embodied or formed across the entire width of flow surfaces 44 or 44 ′.
  • This variant can be achieved in simple constructive terms.
  • FIG. 16 shows a diagrammatic representation of a particularly preferred arrangement according to the invention.
  • tobacco can be fed separately from two supplies 80 and 80 ′ to ducts 40 and 40 ′.
  • This provides the advantage that different cigarette brands or cigarette rods of different tobacco can be produced on one cigarette rod maker or in an arrangement of the type according to the invention.
  • these are respectively two rods of different types of tobacco.
  • the features of the device for feeding tobacco from tobacco gate 11 or 11 ′ and pre-distributor 10 or 10 ′ to ducts 40 and 40 ′ correspond to those features of FIG. 1, in which elements of the second device for conveying and pre-distributing tobacco from FIG.
  • the flow surfaces 44 and 44 ′ are preferably arranged essentially parallel in the embodiments.
