  • This invention concerns improvements in or relating to tobacco-manipulating machines (for example continuous rod cigarette-making machines) in which a continuous tobacco filler is formed, which filler (for example after being enclosed in a paper Wrapper) is to be cut at intervals to form individual tobacco articles such as cigarettes.
  • tobacco-manipulating machines for example continuous rod cigarette-making machines
  • filler for example after being enclosed in a paper Wrapper
  • a tobacco filler It is usual to form a tobacco filler from a relatively loose stream of tobacco, which is compressed laterally so as to give it a reduced and uniform cross-sectional size. Thus if there is more tobacco at some parts of the stream than at others, the compressed filler will have corresponding parts of greater and less density, and accordingly, one known way of forming such a filler is to add increments of tobacco at suitable intervals along the stream.
  • a method of forming a tobacco filler which has more tobacco at desired portions than at others, which comprises the steps of forming a tobacco stream, and removing tobacco from the stream in such a way as to leave more tobacco at the said desired portions than at others.
  • the stream thereafter may be subjected to lateral compression to form a filler of substantially constant cross-sectional size.
  • a method of forming a tobacco filler which is denser at desired portions than at others which comprises the steps of supplying tobacco to a travelling surface in sufficient quantity to form a stream whose average depth is greater than required, removing tobacco so as to reduce the average depth of the stream to a desired extent, in such a way that the depth at the said desired portions is greater than at other portions, and laterally compressing the stream to substantially constant cross-sectional size.
  • the depth of the stream may be reduced along the whole of its length but by a smaller amount at the said desired portions than elsewhere.
  • means for forming a tobacco filler which has more tobacco at desired portions than at others comprising means to form a tobacco stream on a travelling surface, and a trimming device arranged to remove surplus tobacco from the stream in such a way as to leave more tobacco at the said desired portions than at others.
  • Means may be provided to compress the stream after such a trimming to substantially constant crosssectional size.
  • the said trimming device may comprise a pair of rotatable discs to which engage the stream from opposite sides so as to co-operate to determine the depth to which the stream is trimmed, the said discs having recessed parts which co-operate to allow the stream to retain a greater depth of tobacco at the said desired portions than at others.
  • the said discs may have co-operating edges which closely approach each other to separate surplus tobacco from the stream, the said recessed parts having similarly co-operating edges which are a greater distance from the said travelling surface than are the edges of the other parts of the discs.
  • the trimming device may further comprise a member verse walls 3, 4 of a discharge hopper.
  • a rotating brush arranged to engage and sweep away surplus tobacco separated from the stream by the edges of the discs and of the recessed parts.
  • FIGURE 1 is a diagrammatic longitudinal section showing the upper or feed portion of a cigarette-making machine in which a tobacco filler is formed;
  • FIGURE 2 is a longitudinal section showing diagrammatically, on a larger scale, a stream of tobacco as orig inally formed;
  • FIGURE 3 is a plan view of a trimming device
  • FIGURE 4 is a vertical section taken upon the line IVIV of FIG. 3.
  • tobacco is fed by a distributor 1 on to an endless belt conveyor 2 between the trans- The stream of tobacco travels on the band 2 towards the cigarette-rodfor-ming mechanism.
  • the stream of tobacco formed on the conveyor 2 is uneven in height, being characterised by alternating troughs and crests, and its longitudinal section is shown diagrammatically in FIGURE 2, in which the unevenness of its height is considerably exaggerated.
  • the stream of tobacco contains moretobacco than required for making cigarettes having the desired average weight, and the excess tobacco is trimmed olf at the region indicated by the reference 5.
  • This trimming step consists in separating and moving away from the stream any tobacco above the level 11 (FIG. 2), in those portions of the stream where it is desired to have a normal density of the filler, and above the level hl in the portions where a greater tobacco density is desired.
  • These last-mentioned portions are normally spaced from one another by a distance 1 (FIG. 2) equal to the length of one cigarette, so that in each cigarette the tobacco will be somewhat denser at both ends. However, if it is desired to increase the density of the tobacco at only one end of the cigarette the thicker portions may be spaced apart by a distance equal to two cigarettelengths.
  • the length of these thicker portions is usually about In the embodiment described herein this height h is about A" and therefore the height 111 is about or nearly
  • the stream of tobacco is carried along by the travelling band 2 moving in a horizontal channel 6, FIGURES 3 and 4, and having its edges 7 guided and held by side plates 8.
  • the initial portion of this channel is tapered to compress the tobacco therein, and the next portion has its edges parallel and spaced about apart in the
  • the trimming device for separating and discharging the excess tobacco comprises two horizontal rotary discs 9, having chamfered edges, and rotating in opposite directions as shown by the arrows in FIG.
  • a cylindrical rotary brush 10 about A" thick, overlies the discs 9 and is mounted in a shaft 11 rotatably driven at high speed and set at an angle with respect to the direction of flow of the tobacco, as shown. brush is positioned in the zone where the discs are nearest to each other and brushes against the upper surfaces of the discs at that zone, thereby engaging and removing surplus tobacco which is above the discs and completing the separation of that tobacco from the tobacco beneath This 3 the discs.
  • the tobacco thus removed is driven by the brush between the walls 12 and 13 Which guide it on to a travelling band (not shown) by which the excess tobacco is returned to the distributor.
  • the discs 9 rotate at a velocity in revolutions per minute which is equal to one-fourth of the number of cigarettes produced per minute.
  • the outer peripheral parts of the discs are not at a uniform level but are formed with four raised portions 14, whose under-surfaces are recessed as shown in FIG. 4, They are spaced 90 apart and have raised edges situated -.08 above the level of the remaining portions of the discs th'er'ebetween.
  • the two discs are so disposed that as they rotate, successive pairs of raised portions 14 register with one another as shown in FIGURE 3.
  • These raised portions are bounded by straight edges 19 set at suitable angles relative to radii terminating at the outer peripheral edges of the disc. These angles are suitably chosen so that when two raised or recessed portions 14 register with each other, their leading edges 19 are momcntaiily in line with each other as shown in FIGURE 3. l
  • the raised or recessed portions 14 thus pass over the stream of tobacco at intervals each corresponding to one cigarette-length. Moreover, when two portions 14 register with each other on the line IV-IV of FIGURE 3 they are directed as shown with their leading edges substantially parallel to the plane of the rotary brush 10.
  • the recessed portions 14 allow the stream to retain a greater depth of tobacco than do the remaining parts of the discs.
  • This brush 10 is so adjusted as to be substantially flush with the lower portions of the upper faces of the discs 9.
  • the bristles of the brush are slightly bent, see FIGURE 4, and the excess tobacco is removed from these raised portions without difiiculty.
  • the stream of tobacco in its subsequent travel on the band 2 has at the desired spaced intervals portions containing a greater quantity of tobacco than the remaining zones located therebetween.
  • This stream of tobacco is subsequently caused to "pass under a'wheel 15 which compresses it laterally and forms a tobacco filler of uniform cross-sectional size in which the tobacco at the said desired portions is denser than at others.
  • This rod is then delivered on to a paper web 16 passing over a small roller 17 on to an endless band 18 by which the paper Web supporting the filler of tobacco is carried along through the actual rod-forming mechanism.
