Definitions

  • Cited piece cigarettes in which the poorer quality ends are UNITED STATES PATENTS concealed.
  • Triple length rods may be subdivided by two rotary knives, the centre cigarettes have two exlflggz i fi z z Q cellent ends and may be used as plain cigarettes.
  • a method of manufacturing cigarettes which comprises cutting an axially-moving continuous cigarette rod into multiple cigarette length rods, cutting such multiple length rods while they are moving laterally to produce individual cigarette lengths, arranging cigarette lengths so produced into axially aligned pairs in which the outermost ends are ends resulting from cutting the multiple cigarette length rods, inserting a mouthpiece portion between the cigarette lengths of each pair, joining the cigarette lengths and mouthpiece portions by encircling bands, and cutting through the mouthpiece portions to produce individual mouthpiece cigarettes.
  • the multiple length rods can be produced by using a single cut-off knife, thus, in the case of double length rods, reducing the knife speed to onehalf that required for cutting single cigarette lengths. They can, however, if desired be produced by using two knives instead of one, and in that case the knife speed for producing double length rods can be reduced to one quarter that required for cuttingsingle lengths.
  • Quadruple length rods are subdivided into single lengths in one or more operations. For example a quadruple length can be subdivided into'four, while moving laterally, by three disc knives. lf triple length rods are produced these may be cut into three, while moving laterally, by two disc knives. The centre cigarette of each three may then be removed. The remaining two cigarettes are then treated as if double length rods had been used.
  • the multiple lengths can be deflected sideways from the rod line by a rotating fluted drum on which they travel one behind the other and are subdivided by a rotary disc knife. Assuming that the multiple lengths are double lengths, their subdivision produces two rows of single length cigarettes. These can be considered as arranged in pairs of aligned cigarettes, but the good ends of each pair (i.e., the ends produced by the disc,
  • each cigarette in one row is picked off the drum, displaced lengthwise across and past the other row, and replaced on the drum.
  • the good ends of each pair are the outermost, outward-facing ends.
  • this rearrangement can be achieved by providing a suction transfer roller adjacent the fluted drum arranged to pick up each successive cigarette in one row; these are in succession moved lengthwise (e.g., by blowing) along the transfer roller and finally replaced on the fluted drum.
  • both the fluted drum and the transfer roller must of course be long enough for the purpose.
  • FIG. 1 illustrates schematically an example of a method according to the invention
  • FIG. 2 is an end elevation of apparatus according to the invention.
  • FIG. 3 is a view on the line llI-lIl of FIG. 2.
  • stage i a double-length cigarette rod D
  • stage II shows the latter after subdivision into two single cigarette lengths A, B
  • stage III shows these two lengths rearranged
  • stage IV shows a double length mouthpiece portion S inserted between the cigarette lengths
  • stage V shows the two cigarette lengths united with the double length mouthpiece portion
  • stage Vl shows the assemblage of stage V severed at Z to produce two mouthpiece cigarettes Cl and C2.
  • the ends of the double-length rod D are marked X.
  • the ends of the cigarettes produced by subdivision of the rod are marked Y.
  • the exposed ends are the ends Y.
  • FIGS. 2 and 3 there is shown a first drum 1, a rotary disc knife 2 and a second drum 3.
  • the drum 1 is the catcher drum of a continuous rod cigarette making machine and has a plurality of flutes 4. It is rotated at such. a speed as to receive in each momentarily uppermost flute a double length cigarette rod D, the rods D being produced in succession by the cut-off mechanism C0 of the cigarette making machine.
  • the drum 1 has a stop 7 in each flute 4 which arrests the axial motion of the rods D so that a laterally moving row of rods D is formed on the drum 1.
  • the disc knife 2 extends into a circumferential slot 6.
  • a braking roller is shown at 5. This has the shape of a solid of revolution of the curvature of the drum 1.
  • the surface of the roller 5 bears lightly against the double-length rods D to slow them down as they enter the flutes 4.
  • the drum 1 rotates in the direction shown by the arrow to carry each rod D in succession past the rotary disc knife 2 which subdivides them into single cigarette lengths A and B to form two rows of cigarettes. These events correspond to stages I and II of FIG. 1.
  • FIGS. 2 and 3 the multiple length rods and cigarette lengths shown have the nomenclature corresponding to that of FIG. 1, of D for double length rods and A and B for individual cigarette lengths. It will be appreciated that in FIG. 2 some flutes will contain both a cigarette A and a cigarette B, and to indicate this, and also to indicate which cigarette is in front and can therefore be seen, and which cigarette is behind and is concealed, the cigarettes are indicated by the reference letters A, B in that order where a cigarette B is concealed by a cigarette A, and by the reference letters B, A'in that order where a cigarette A is concealed by a cigarette B.
  • the cigarettes A are referenced A1, A2, A3 etc.
  • the cigarettes B are referenced B1, B2, B3 etc., starting from the point of subdivision of the rods D by the knife 2.
  • the cigarettes shown at corresponding positions in FIG. 3 bear the same references.

  • a shroud ll surrounds the drum 3 to prevent the cigarettes from falling out-and in place of being blown along the flutes the cigarettes could be sucked along them.
  • a stop 12 is provided in each of the-flutes 8 to align the cigarettes B.
  • the cigarettes B could be moved along the flutes by means of a helical guide. In this case the cigarettes would have to stand' proud of the drum 3.
  • the helical guide could be an internal rib on the shroud 11.
  • FIG. 3 shows the progressive displacement of the cigarettes B to B17 along the length of the drum 3.
  • cigarette A4 is retained in flute 4 whilst from in front of it, as viewed in FIG. 2, cigarette B4 is transferred into the flute 8, and behind it cigarette B17 is transferedinto the same flute 4.
  • a still further fluted drum 15 carries double length mouthpiece portions S in its flutes l6, and each portion S is placed between a pair of cigarettes A and B in a flute 14. This is stage IV of FIG. 1.
  • stage V The two cigarettes and the mouthpiece portion are then closed up together, are united by an encircling band (stage V) and are then severed to form two mouthpiece cigarettes (stage VI).
  • the drums I, 3, 13 and 15 have suction applied to their flutes in the following manner.
  • the flutes 4 are connected to the centre of the drum 1 by radial drillings 17.
  • a stationary valve 18 applies suction to the part of the flutes occupied by the rods D and the cigarettes A and B between the points 19 and 20. Between the points 20 and 21 suction is cut off from the right hand row of cigarettes B, as viewed in FIG. 3, so that these cigarettes may be transferred into the drum 3.
  • suction is applied to the part of the flutes 4 occupied by the left hand row of cigarettes B, as viewed in FIG. 3. All suction is cut off from the flutes 4 between the points 21 and 19.
