Definitions

  • the present invention relates to a method for making smoking articles, smoking articles, and more particularly to a method for manufacturing smoking articles having a reduced ignition propensity.
  • One method for making wrappers for smoking articles having reduced ignition propensity is to add bands of paper to the wrapping paper, wherein the composition of the wrapper and the band paper are selected to yield a composite paper having the desired burn rate, as disclosed in EP 0 483998 and EP 0 262550.
  • the bands are typically applied to the paper before it is wrapped around a tobacco core, and when the paper is wrapped around the tobacco the bands are on the inside of the paper, facing the tobacco. When the paper is used to manufacture the cigarettes, the bands are randomly situated along the length of the cigarette.
  • the machines used for wrapping cigarettes which may be modified to include a section for applying a burn retardant solution, apply significant tension to the paper and when the paper is damp its tensile strength is significantly reduced so that tearing of the paper easily occurs.
  • Various heaters can be included in the machine to assist in drying the paper but to allow time for these to properly dry the paper, the machine must be slowed. The slowing of the machine may also alleviate problems with tearing, but this decreases production efficiency.
  • the present invention provides a method of manufacturing a smoking article comprising providing a filter element and at least one rod of smokeable material surrounded by a wrapper, wrapping a section of tipping paper around the filter element and a portion of the at least one wrapped rod and applying one or more patches of material to the outer surface of the wrapper.
  • the present invention also provides a smoking article comprising a rod of smokeable material surrounded by a wrapper, a filter element at one end of the wrapped rod, a tipping paper surrounding the filter element and a portion of the wrapped rod and a patch of material applied to the outer surface of the wrapper.
  • the step of applying the one or more patches of material to the wrapper of the at least one wrapped rod can be performed in association with the step of wrapping the section of tipping paper around the filter element and an end of the at least one wrapped rod. In this way, modification to existing cigarette manufacturing processes in order to apply the additional patches can be minimised and production rates are not limited by the modification.
  • the step of providing a filter element and at least one rod of smokeable material surrounded by a wrapper can comprise providing first and second rods of smokeable material surrounded by wrappers, and a filter element interposed between the first and second rods, and the method can further comprise cutting the filter element to form two smoking articles after application of the one or more patches.
  • the method can also comprise splitting tipping paper from a roll to form both the patches and the section to be applied to the filter element and the ends of the wrapped rods.
  • the one or more bands can be spaced from an edge of the tipping paper and/or have a width of at least 4 mm.
  • the material for the patches can be the same as the tipping paper material, although additional printing may be used on the section of material used on the tipping paper or bands.
  • FIG. 1 is a schematic illustration of a method of manufacturing a smoking article according to an embodiment of the present invention
  • FIG. 3 shows a smoking article in which a window in a patch exposes a region of underlying wrapper
  • the patch sections 12 B 1 and 12 B 2 form an LIP band on each wrapped rod 30 and are applied to the wrapped rods 30 online during cigarette manufacture, in a process step associated with the step of applying the tipping paper section 12 A to connect the filter to the wrapped rods 30 .
  • the patch sections 12 B 1 and 12 B 2 can be applied simultaneously to applying the tipping paper section 12 A or can be otherwise applied in the same phase of manufacture as that in which the tipping paper section 12 A is applied, for instance after formation of the wrapped rods 30 .
  • FIG. 2 shows a smoking article in the form of a cigarette, in accordance with an embodiment of the present invention, having two LIP bands A, B.
  • the cigarette comprises a wrapped rod 30 and a filter attached to the wrapped rod 30 by tipping paper 2 which covers the filter and overlaps the wrapped rod 30 .
  • the wrapped rod 30 comprises a tobacco core surrounded by a paper wrapper.
  • the length of the tipping paper 2 is L T and the exposed length of the wrapped rod 1 (before the LIP bands A, B are applied) is L W .
  • a first LIP band A has a first width W A and is positioned spaced from an edge of the tipping paper 2 by a first distance a.
  • the first band A is positioned within the first 50% of the exposed length of the wrapped rod 1 ie (W A +a)/ L W ⁇ 0.5.
  • the second band B is spaced from the first band A and positioned within the last 50 % of the exposed length of the wrapped rod 1 ie (L W ⁇ b)/ L W ⁇ 0.5.
  • the base material used for the LIP bands is the same as that used for the tipping paper (although different printing may be used on each section) and preferably has a porosity of approximately 5 Coresta Units (CU).
  • LIP-compliant cigarettes were manufactured having a single 5 CU porosity LIP band applied per cigarette in a 6 mm or 8 mm width and with the mouth-end edge of the band being 50 mm from the mouth end of the cigarette.
  • the banding material was adhered to the tobacco rod with water-based glue.
  • the width of the LIP patch 12 B 1 , 12 B 2 may optionally be substantially equal to the length L W of the region of wrapped tobacco rod 30 which is not covered by the sheet of tipping paper 2 connecting the wrapped rod 30 to the filter.
  • FIG. 3 shows an LIP patch C which extends substantially from the edge of the tipping paper 2 which is furthest from the mouth end of the smoking article to the opposite end of the wrapped tobacco rod 30 .
  • the LIP patch C comprises one or more windows 3 which expose the underlying wrapped tobacco rod 30 to the surrounding atmosphere.
  • Each window 3 comprises a hole in the patch C of LIP material.
  • the windows 3 may be cut-out from the LIP sheet material before the material is applied to the wrapped rod 30 .
  • the windows 3 can be cut-out from the material before the material is wound onto the bobbin or reel 13 .
  • the regions of the patch C between the windows 3 fully circumscribe the wrapped tobacco rod 30 . Therefore, the regions of the patch which do not align with a window 3 can be considered as corresponding to the LIP bands A, B described above.
  • the patch C thus provides the same LIP effect as the LIP patches A, B previously referred to. Specifically, burning of the wrapped tobacco rod 30 is hindered in the regions of the rod 30 which are covered by the LIP patch A, B, C whilst burning of the rod 30 is less hindered in the regions of the rod 30 which are not covered by the patch A, B, C.
  • the rate of gaseous transfer between the tobacco and the surrounding environment, for example the surrounding air, through the windows 3 in the patch C mirrors the rate of gaseous transfer through the un-banded regions of the wrapped rod 30 shown in FIG. 2 and as previously described.
  • the location of the windows 3 may be opposite to the location of the LIP bands A, B described above.
  • a first window 3 in the LIP patch C may extend between a location which is a distance of (a+W A ) from the edge of the tipping paper 2 and a location which is a distance b from the edge of the tipping paper 2 .
  • the width of the first window is therefore (b ⁇ (a+W A )).
  • a second window 3 may extend between a location which is a distance of (b+W B ) from the edge of the tipping paper 2 and a location which is a distance of L W from the edge of the tipping paper 2 .
  • the width of the second window 3 is therefore (L W ⁇ (b+W B )). This is also shown in FIG. 3 .
  • FIG. 4 shows another example, in which a window 3 extends between a location which is a distance of (a+W A ) from the edge of the tipping paper 2 and a location which is a distance of L W from the edge of the tipping paper 2 .
  • the width of the window 3 is therefore (L W ⁇ (a+W A )).
  • circumferential regions of LIP material are provided around the same regions of the wrapped tobacco rod 30 in both the embodiment shown in FIG. 2 and the embodiments shown in FIGS. 3 and 4 . Similarly, the wrapped tobacco rod 30 in between the circumferential regions of LIP material is largely exposed.
  • the LIP patch material comprises the same material that is used for the tipping paper 2
  • a sheet of the material can optionally be applied over the whole length of a double length cigarette of the type shown in FIG. 1 before cutting the double length filter in half.
  • the windows 3 should be cut-out from the LIP material beforehand.
  • the tipping paper 2 and patch C are shown using a different pattern in order to allow the reader to clearly distinguish between the two.
  • the tipping paper 2 and patch C may in practice be made of the same type of material.
