Definitions

  • This invention concerns improvements relating to the manufacture of multiple cigarette-smoke filters.
  • An object of the present invention is to make it possible to produce quickly and conveniently multiple filters incorporating sections containing powdered or granular material capable of filtering cigarette smoke, for exa-mple charcoal, silica gel, zeolites or activated alumina and sections consisting of filter plugs made, for example, of cellulose acetate, viscose or polyolefin fibres or of sheet material such as paper.
  • apparatus for the purpose set forth comprises means for feeding quantities of powdered or granular filter material and lengths of filterplug material to an assembly point and means operative at the said point for combining the said quantities and lengths in vertical superimposition.
  • successive assemblies are carried away from the assembly point in rod form, with which object they may be wrapped after leaving the said point.
  • a continuous rod thus produced may then be passed through sealing and forming devices to cut-off means.
  • the feed means may operate by gravity alone or may be pneumatically assisted.
  • Such apparatus has the advantage that, with vertical superimposition ofthe materials, the powdered or granular material can be evenly distributed over a plane perice pendicular to the longitudinal axis of the assembly or rod which is produced. Also the plug material can be caused to come to bear firmly upon the sections or beds of powdered or granular material, holding them vin the evenly distributed state during subsequent wrapping and sealing.
  • FIGURE 1 is a side elevation of one form of apparatus for producing multiple filters
  • FIGURE 2 is a vertical section on the line II-II in FIGURE 1.
  • FIGURE 3 is a plan view of the apparatus
  • FIGURE 4 is a perspective view of another form of apparatus.
  • the form of apparatus illustrated in FIGURES l to 3 comprises upper and lower feed wheels 1, 2 rotatable about vertical axes 3, 4 respectively.
  • the upper wheel 1 is perforated ne-ar its periphery with holes 5 adapted for receiving double-lengths of filter-plug material and holding them vertically, i.e. with their longitudinal axes perpendicular to the plane of the wheel 1.
  • the wheel 2, disposed immediately below the Wheel 1, is of larger diameter and is similarly perforated with holes 6 each adapted for receiving a measured quantity of powdered or granular material or for itself measuring out the said quantity.
  • the grain size of this material is between 10 and 40 British Standard mesh, but finer material can be employed.
  • the axes 3, 4 are offset in relation to each other, but so that the upper wheel 1 falls within the lower wheel 2 as seen in plan View (FIG. 3) and that the holes 5, 6 in the upper and lower wheels 1, 2 coincide at only one point 7, where assembly occurs.
  • the wheels 1, 2 are driven in the same direction through a common gear wheel 8 meshing with teeth 9, 10 at the peripheries of the respective wheels.
  • Plug lengths are fed into the holes v5 in the upper wheel 1 from supply means which is shown as a pneumatic-conveyor tube 11, but may be a hopper.
  • the powdered or granular material is supplied from a hopper 12 to the holes 6 in the wheel 2, at a point where it is not overlaid by the wheel 1.
  • the holes 6 themselves serve to measure out the required quantities of material. If preferred, however, additional means may be provided for feeding accurately measured quantities to the holes 6.
  • Fixed underneath the wheel 2 and extending, at least, from the hopper 12 to the assembly point 7 is a retaining plate 13 of sufiicient width to close the lower ends of the holes 6 in the wheel 2, except at the point 7, Where the plate 13 is likewise provided with a hole 14 (FIG.4 2).
  • a tube 15 with an internal diameter slightly larger than the diameter required for the finished filter rod is attached by a boss to the plate 13 in vertical alignment with the hole 14 and with the point 7 of coincidence of the holes 5, 6 in the wheels 1, 2.
  • Van air nozzle 16 is arranged above the point 7 to provide an air jet for assisting transfer of the filter assemblies into the tube 15.
  • Wrapping-paper strip 17 from a reel passes over a roller 18 into a funnel-shaped guide 19 which leads it around the reduced and obliquely terminated lower end 20 of the tube 15, where it becomes wrapped tightly around each emerging assembly with the assistance of a guide 21.
  • the paper strip 17 is coated with a heat-seal composition.
  • a vertically disposed heater 22 which may be an electrical seam heater such as is used in conventional cigarette-making machines.
  • the wrapped assembly now in the of 0.318 inch and was provided withV six longitudinal form of a continuous rod, is carried, with the assistance of a garniture tape 23, through a conventional garniture 24.
  • the garniture thus serves to draw the rod through the machine, the paper strip 1'.' being freely running and not itself driven. Difiiculties due to slip can be avoided in this manner.
  • the rod is cut at 25 into lengths suitable for subsequent sub-division into individual triple filters for incorporation in cigarettes. ln the individual filter7 a section f powdered or granular material remains held, within the wrapping, between single-length sections of plug material.
  • the cutting is effected by a conventional cut-off device comprising knives operating in a horizontal plane.
  • a plain paper strip 17 may be pasted or glued in the apparatus.
  • a pasting wheel is arranged to apply paste to the overlapping edges of the strip 17 immediately before it is completely closed to form a wrapping.
  • an inlet may be arranged to communicate with the inside of the tube 15 to allow paste to be applied to the filter materials before wrapping in order to assist in sealing the materials to the strip.
  • the continuous rod then passes through a vertically disposed seam heater and is cut into lengths, as described above.
  • the rod may be driven by means of successive rubber feed rollers and the paper strip 17 may itself also be driven by geared feed rollers.
  • filter-plug lengths 26 are Ifed in vertical align ement from a pneumatic tube 11 to a point 27 adjacent to the assembly point '7 on the upper surface of the wheel 2 for supplying the measured quantity of powdered or granular material.
  • the wheel 2 is rotated intermittently, through one pitch of the holes 6 at a time, by a drive i controlled by. an indexing unit.
  • Two push rods 28, 29, operating in timed relation with the intermittent move- ⁇ ment of the wheel 2 are arranged to bring each plug length 26 into position.
  • One push rod 28, operating substantially parallel to a diameter of the wheel 2 moves the plug length from below the tube 11 to a position co-axial with the hole 6 at the assembly point 7 and with the hole 14 (not seen) in the plate 13, vwhile the other push rod 29, operating vertically from above the said point, ensures both close contact between each plug 26 and the powdered or granular material in the hole 6 and complete transfer of the plug length and powdered or granular material into a tube similar to the tube 15 of the apparatus of FIGS. 1 to 3.
  • the rod thus formed is then wrapped and sealed and cut up as described above.
  • the push rod 28 operates radially of the wheel 2, but it could be arranged to operate tangentially.
  • a perforated brass disc rotating between the nozzle 16 and the upper wheel 1 was arranged to act as a valve so that the air-jet, supplied at 60 lbs. per sq. inch, only H functioned when holes 5 and 6 were aligned over the hole 14V and tube 15.
  • the tube 15 hady an internal diameter slits to allow the air to escape.
  • the paper 17 was polyethylene coated paper 0.003 inch thick and 27 mm. wide.
  • the heater 22 was 3.5 inches long and of 0.315 inchinternal diameteLr
  • the garniture 24 was 10l inches long and designed toproduce filters of 25 mm. circumference.
  • the rod produced was-cut through each six plug length to givey a rod length comprising six triple filters each with end sections, 7.5 mm. long, of cellulose acetate and a middle section, 5 mm. long, of carbon granules.V y l
  • the dimensions of the wheels 1 and 2 can be selected to suit requirements. Thus, their diameters can be increased if higher production speeds are required. Their thicknesses will depend upon the lengths of the respective sections of the different materials.
  • the apparatus is not confined to the production of triple ilters such as have been referred to above'.
  • filters comprising, Say, three short plug lengths and two narrow sections of powdered or granular material or a thin waferyof the latter material between two retaining plugs.
  • the holes 5 in the wheel 1 may be arranged to taper downwardly, from the upper end to a short distance from the lower end, in orderto facilitate entry of the plug lengths. rl ⁇ his taper. may also be increased by displacing the leading edge of the upper end ofthe hole in theV direction of rotation of the wheely 1, so ⁇
  • the upper end of the hole is bounded by two semicircular portions joined by short straight portions.
  • the hole may taper from 0.335 inch at the upper end to within 0.125 of the lower end.
  • the leading edge may be displaced by 0.050 inch in the direction of rotation.
