  • the parts 35 of the grill form louvres or guide elements by which air escaping from the passage 12 through the opening 31 into the suction chamber 32 is guided out of the passage downwardly, that is, in a rearward direction considered in the direction of movement of the air upwardly through the passage 12.
  • the suction chamber 32' is tapered, increasing in depth from right to left in FIG- UR'E 2, that is, in the direction of movement of the conveyor band 20.

  • the plate 49 is apertured to allow air to fiow over an edge of the plate into the chamber 51, and out of the chamber through a central aperture.
  • the air discharged by the fan 41 passes through a conduit 53 to a multi-unit cyclone 54 by which, after removal of dust, the air is discharged to atmosphere. Accordingly the air drawn into the passage 12 and air duct 8 consists of air from the diffuser 35 mixed with atmospheric air.
  • a further dust-separating device 55 is provided in the conduit 53 and is connected by a pipe 56 to the channel through which the band 20' moves, at a position beyond the passage 12 (i.e, to the left of the end Wall 13 in FIGURE 2) so as to convey a certain amount of short tobacco particles to the tobacco filler. This can be controlled or put out of action if desired by a valve 57.
  • a trimming device comprising a pair of discs 60 (only one of which is visible in the figure) is located beyond the passage 8 to trim the tobacco filler formed on the conveyor band 20 and held thereon by suction.
  • a paper web 61 is led over a tape 62 which runs in a trough 63, the paper web being led directly beneath the conveyor band 20 at a position where the latter still extends beneath the suction chamber '25.
  • Folding, gumming, and sealing devices are provided to wrap the paper web around the tobacco filler to form a continuous cigarette rod.
  • a pivoted flap 64 is located at the position where the conveyor band so carries the tobacco filler out of the passage 12, and acts to prevent or hinder air from flowing into the passage from atmosphere through the gap between the tobacco filler and the end wall 13.
  • the tobacco thus fed to the conveyor band 20 builds up on the band, as the latter travels from right to left, FIGURE 2, and forms a filler, the tobacco being held by suction to the band as the filler is formed.
  • the suction exerted on the filler through the perforated conveyor band is Such as to compress the filler laterally (that is, in a direction towards the band) to a density at least half that required in the final cigarette rod and cigarettes produced from the rod.
  • the tobacco in the partly formed filler is better able to withstand the impact of tobacco particles which are impelled against it at high velocity by the air stream to continue the formation of the filler.
  • the filler so formed is compressed to a substantial degree, the mechanical work required to compress the filler to rod size preparatory to enclosing it in the cigarette-paper Web is considerably reduced.
  • the air stream flowing through the passage 12 is required to move at high speed in order to cause tobacco particles to move through the passage up to the conveyor hand without deceleration such as would cause them to bunch together or agglomerate.
  • the air velocity should be high enough to impart sufficient velocity to tobacco particles entering the passage to cause them to move apart from one another, by rapidly increasing the speed of successive particles as they enter and move upwardly through the passage. This produces very beneficial effects in the formation of the filler, which can be built up more uniformly and more satisfactorily if the tobacco arrives at the travelling conveyor band 26, and at the partially formed filler carried by the band, as far practicable in the form of discrete, separate particles.
  • This method of forming a tobacco filler is fully described and explained in United States application Serial No. 738,805.
  • the velocity with which air can be caused to flow up the passage is limited by the resistance offered to the air flow by the tobacco on the conveyor band (corresponding to the band 20 in the present case) as Well as the resistance of the band itself.
  • the arrangement according to the present invention by greatly increasing the speeds which can be attained by the tobacco particles in their travel to the conveyor band, makes it possible to obtain the benefits just described, even at very greatly increased speeds of operation of the machine.
  • increased in order to increase the rate of output of the machine the speed at which the air carries the particles through the passage towards the partly formed filler can be correspondingly increased.
  • the limitations on the speed of the air through the passage which exist in a construction in which the only outlet for air from the passage is through the conveyor band and through the tobacco on the band, are removed by the pro vision of an additional outlet, namely the opening 31.
  • the speed of the air stream through the passage can be increased so as to maintain (at any rate to a very great degree) the advantages just described, for virtually any increase in the speed of the conveyor band.
  • the suction chamber 62 increases in depth and volume from right to left in FIGURE 2. This is because the quantity of tobacco at any instant tobacco is just reaching a part of the conveyor band which has just entered the passage, that is at the extreme righthand end of the passage as viewed in FIGURE 2. Accordingly the suction chamber 32 is constructed so that its capacity for air increases'along the length of the passage so that as the resistance of the tobacco to the flow of air through the band 20 increases, more air can flow through the opening 31.
  • the crosssectional size of the suction chamber 32 varies from about 31 square centimetres at its smaller end to about 51 square centimetres at its larger end.
  • FIGURE 5 shows diagrammatically an alternative construction in which a passage 71 formed by side walls 72 extends downwardly towards a trough 73 in which runs a conveyor band 74, formed by Thus if the speed of the conveyor band 20 is suction 'fan, not shown, are provided alongside the side walls of the passage to draw air from the passage through the openings 75.
  • the whole of the air flowing through the passage is drawn off through the openings 75, being directed outwardly, and rearwardly considered in the direction of the air stream in the passage, by the guide elements 75a.
  • the tobacco has sufficient momentum to continue towards the band 74 at high velocity.
  • the air is directed through the passage with sumcient velocity to impart to the tobacco particles a velocity high enough not only to prevent them from agglomerating or bunching together in the passagewhile travelling towards the conveyor band, but also to cause them to move apart.
  • the air stream may be given a velocity in the passage of about 30 feet per second.
  • FIGURE 6 illustrates a further alternative construction in which the passage 71 extends downwardly to the conveyor band 74, but in this case the band 74 is provided with perforations 83 and runs over a suction chamber 84 from which air is drawn by a suction fan through a duct 85.
  • air may be caused to flow through the passage at a very high velocity, since a proportion of the air is drawn from the passage through the openings 75, andthrough suction chambers 76 and ducts 77 as in the construction shown in FIGURE 5.
