Definitions

  • This invention relates to a method and apparatus for the manufacture of filter-tipped cigarettes, which method includes shaping of filter-tipped cigarettes to an other than circular cross-section.
  • the above standard method of cigarette production is especially suited for making cigarettes of circular cross- section. This method is not easily adapted to produce cigarettes of non-circular cross-section.
  • the main problems in adapting the standard method to produce non-circular filter-tipped cigarettes are, tire difficulty one experiences in aligning the non-circular filter element and the non ⁇ circular tobacco rods, and the difficulty one experiences in wrapping the non-circular tobacco rod/filter assembly.
  • the shape of the outer circumference of the cigarette will vary as the cigarette rotates about its longitudinal axis and there will probably be one or more preferable positions for the print on a non-circular cigarette.
  • U.S. Patent No. 579,421 discloses a method of making an oval tobacco rod by compressing tobacco material fed to an oval garniture. More recently, WO 84/03819 discloses a filter plug drum having grooves adapted to receive single oval filter plugs and means to orient the oval filter plugs to a specific orientation as they leave the plug drum. GB 2 170 986A discloses a method of intercalating multi-element smoking articles of non-circular cross section. This document deals with the problem of aligning oval filter rods and oval tobacco rods into a common axial orientation and cross-sectional orientation. The problem with the above referenced disclosures is that they are complicated and they also require specific, expensive and highly modified machinery.
  • the present invention provides a method of producing filter-tipped cigarettes of non-circular cross-section, wherein a filter-tipped cigarette of circular cross-section is compressed over the full length thereof in a compression zone between a first surface and a second surface, said first surface and said second surface being movable relative to one another, and said compression zone being provided with means for removing the compressed non-circular filter ⁇ tipped cigarette therefrom.
  • the present invention further provides apparatus operable to produce filter-tipped cigarettes of non-circular cross-section, the apparatus comprising a first surface and a second surface moveable relative to one another, said first surface and said second surface providing a compression zone, at which compression zone the maximum distance between said first surface and said second surface is less than the diameter of the circular cigarette, said compression zone being provided with means for removing the compressed non-circular filter-tipped cigarettes therefrom.
  • the filter-tipped cigarette of circular cross-section is preferably a single cigarette, but may be in the form of a double cigarette assembly as described above.
  • An advantage resulting from using complete or substantially complete circular cigarettes is that all the features of a conventional production process, for example, on-line ventilation, can be incorporated into the non-circular filter-tipped cigarette. Some of these features would be otherwise difficult to incorporate into a cigarette which is made from the outset as a non-circular filter-tipped cigarette, for example, an oval cigarette.
  • on-line laser ventilation the cigarettes must be rotated whilst the laser perforates the cigarette tipping as required. If the cigarette was made as an oval cigarette it would be difficult to rotate the oval cigarette in such a manner as to ensure application of evenly spaced ventilation holes.
  • the circular cigarette comprises pre ⁇ printed tipping paper, for example, carrying a pre-printed brand name.
  • the first surface and the second surface move with rotative motion relative to one another.
  • the first surface and the second surface are preferably driven by the same drive gear to ensure that both the first surface and the second surface move at the same speed relative to one another.
  • the first surface may comprise one or more flutes shaped to produce the desired non-circular cross-section.
  • the shape of the flutes will vary depending upon the cross- section of the non-circular cigarette desired.
  • the flutes may be shaped to produce cigarettes of various cross- sectional shape, for example, oval, square or some other polygonal cross-section. As used herein, the term oval incorporates elliptical and ovoid cross-sections.
  • the first surface may be a plain surface, i.e. without flutes.
  • the second surface may be a plain surface or a fluted surface.
  • one or both of the first surface and the second surface takes the form of a drum.
  • the drum is of substantially circular cross-section.
  • both the first surface and the second surface comprise flutes
  • the first surface and the second surface should be so arranged that the flutes coincide as the first surface and the second surface move relative to one another.
  • first surface and the second surface may be a resilient, elongate surface.
  • Guide means may be provided on the undersurface of the resilient elongate surface to ensure good tracking.
  • one or both of the fir ⁇ t surface and the second surface may comprise essentially elliptical surfaces.
  • the first and second surfaces comprise a drum
  • at least one of the surfaces should be provided with means to hold the cigarettes on the surface.
  • the means to hold the cigarette on the first surface comprises means to provide a vacuum.
  • the means to provide a vacuum comprises a series of vacuum ports.
  • the flutes of the fluted drums comprise a small number of large vacuum ports of 2mm-4mm diameter.
  • the vacuum ports are smaller than conventional vacuum ports, say l-2mm diameter. The reason for this is that when the cigarettes are compressed the vacuum ports may mark the surface of the cigarettes. Larger vacuum ports would produce a more noticeable mark on the surface of the compressed cigarette than would smaller vacuum ports. It is, therefore, advantageous that each flute has a larger number of the smaller vacuum ports producing the same effective suction force.
  • both the fir ⁇ t surface and the second surface comprise resilient elongate surface ⁇
  • the compression zone is the region of closest proximity of the first and second surface.
  • the compres ⁇ ion zone compri ⁇ e ⁇ one of the one or more flutes of the first surface and the second surface.
  • the maximum distance of the compression zone between the first ⁇ urface and the second surface is defined as being the distance between the deepest part of the flute on the first surface and the corresponding region of the second surface.
  • the maximum distance of the compression zone will be the distance between the deepest part of the flute on the first surface and the deepest part of the coinciding flute on the second surface.
  • the compression zone comprises the region between the first and second surface in which the maximum distance of the compression zone is less than the diameter of the circular cigarette.
  • the cigarette ⁇ are subjected to a compres ⁇ ion force along the full length of the cigarette.
  • the first ⁇ urface and the second surface constitute integral features of a conventional cigarette production line.
  • the apparatus according to the present invention may be incorporated at the end of a conventional cigarette production line.
  • the location of the invention within the conventional cigarette production line will depend to some extent on whether or not the circular cigarettes fed to the compression zone are single or double cigarette assemblies. If they are single cigarette assemblies, then the inventive apparatus can be added onto the end of a conventional cigarette production line. In the event that double cigarette assemblies are fed to the compression zone, the inventive apparatus will have to be incorporated into the conventional cigarette production line after the rolling process, during which rolling proces ⁇ the tipping paper is wrapped around the cigarette as ⁇ embly, and before the cigarette ⁇ are fed to the cutting and rotating stages of the production line.
  • the means for removing the compressed, non-circular filter-tipped cigarettes from the compression zone may suitably comprise a third surface in the form of a fluted drum, which may be known as a transfer drum.
  • the transfer drum is preferably in rotative motion relative to one or both of the first surface or the second surface providing the compres ⁇ ion zone.
  • the transfer drum preferably feeds the non-circular filter-tipped cigarettes onto receiving mean ⁇ for example, a catcher tray.
  • the direction of rotation of the transfer drum will depend upon the location of the catcher tray relative to the transfer drum.
  • the third surface may be a conveyor onto which the non-circular filter-tipped cigarettes are released after passing through the compres ⁇ ion zone.
  • first surface and/or the second surface can also act as means for removing the compressed non-circular cigarettes from the compression zone and the shaped cigarettes are thereby fed directly from the compression zone to receiving means, for example, a catcher tray by the action of the first surface and/or second surface.
  • An advantage of the present invention is that the proces ⁇ i ⁇ a continuou ⁇ proce ⁇ , which increases the economic feasibility and speed of the overall production of non-circular filter-tipped cigarettes.
  • the dimension ⁇ of the non-circular filter-tipped cigarette produced according to the pre ⁇ ent invention will depend upon the dimensions of the original circular cigarette, the compression force of the compression zone and the shape of the flutes, if flutes are required.
  • a conventional filter-tipped cigarette has a diameter of around 24.75mm and an overall length, including the filter- tip of between 72 and 120mm.
  • a commercially acceptable oval cigarette would suitably have a width of about 10mm and a depth of about 5.8mm.
  • the apparatus i ⁇ therefore arranged so as to ensure that the non-circular cigarette produced has the required dimension ⁇ by varying, for example, the dimension ⁇ of the circular cigarettes, the ⁇ hape of the flute ⁇ , the compre ⁇ ion force and the maximum distance of the compre ⁇ ion zone.
  • the circumference of the filter-tip on a conventional circular cigarette is slightly smaller than the circumference of the tobacco rod to which the filter tip is connected. Therefore, in order that the cross-section of the non-circular filter-tipped cigarette after passing through the compression zone is substantially constant along the full length of the filter-tipped cigarette, it may be necessary to shape the flute so that the cross-section of the flute in contact with the filter tip of the cigarette is of slightly smaller diameter than the section of the flute in contact with the tobacco rod.
  • the filter tip is likely to be more resistant to compression than the tobacco rod.
  • This problem may be overcome by incorporating a heat sen ⁇ itive additive into the filter tip during production of the filter rod, for example, triethyleneglycoldiacetate (TEGDA) .
  • TOGDA triethyleneglycoldiacetate
  • the flute ⁇ may be heated at the filter tip section to cause the heat sensitive additive to be activated during compression so that when the cigarette cools after passing through the compression zone, the filter will be fixed in the desired non-circular cross-section.
  • the filter tip may be subjected to a higher degree of compres ⁇ ion than the tobacco rod of the filter-tipped cigarette.
  • the filter tip is compressed, in this instance, to a thickness which is smaller than the width of the compressed cigarette.
  • an oval cigarette width of 5.6mm may require the filter of-the cigarette to be compres ⁇ ed to a width in the compression zone of less than 5.6mm.
  • the first surface and the second surface comprise resilient elongate surfaces, that portion of the first and ⁇ econd surface which contacts the filter tip may be made thicker inside the compression zone in order to compress the filter tip more than the tobacco rod.
  • the compression force required to produce the non ⁇ circular cigarettes will vary and be dependent on many factors. For example, the firmnes ⁇ of the tobacco rod and the filter, the length of the cigarette and the period of time over which the compre ⁇ ion take ⁇ place. A suitable compression force would be equivalent to a weight in the range of 1.5kg to 10kg. Furthermore, the amount of compression of the cigarette will be limited by the effect which compression has on the smoking characteristics and pres ⁇ ure drop of the re ⁇ ultant cigarette.
  • a filter tip cigarette is compressed to produce at lea ⁇ t a 20% reduction and preferably at least a 25% reduction in rod diameter.
  • the compression force exerted on the filter tip may be increased by decreasing the maximum di ⁇ tance between the first surface and the second surface at the compres ⁇ ion zone in the region of the filter tip.
