Definitions

  • the present invention relates to a cigarette structure wherein tobacco in the cigarette is arranged to provide improved smoking characteristics.
  • highly flavoured tobacco is trimmed from one side of the cigarette and is recirculated in the cigarette-making machine to provide the tobacco layer on the opposite side of the rod.
  • Dense ending techniques may be employed to provide an increased quantity of the highly-flavoured tobacco at the end of the cigarette.
  • Conventional dense ending techniques include the use of a rotary cutter for trimming which has a pocket or notch in it so as to trim a lesser thickness of tobacco as the cigarette end segment of the rod passes the trimmer.
  • the tobacco segment just prior to the trimming point may be compressed, for example, with a rotary compression device having lobes which mechanically compress the tobacco towards the rod-carrying surface.
  • a cigarette formed from two different blends of tobacco and having an approximately uniform delivery of flavour along its length as the cigarette is smoked.
  • the present invention provides a simplified method of assembly of a cigarette filler rod comprising differing blends of tobacco.
  • a first blend of shredded lamina having a first flavour/tar ratio is placed in the left hand side of the hopper, or the side of the hopper which provides the tobacco closest to the rod-forming and -conveying surface, while a second blend of shredded lamina having a higher flavour/tar ratio is placed in the right hand side of the hopper, or the side of the hopper which provides the tobacco on the opposite side of the rod from the rod-forming surface.
  • the hopper then forms a shower of tobacco particles and a filler rod is formed from the shower by passing the rod-forming and -conveying surface transverse to the shower.
  • the higher flavoured tobacco is trimmed from the filler rod and the trimmed tobacco is returned to the left hand side of the hopper to form part of that blend.
  • a dense end device is used to increase the quantity of the higher flavoured tobacco in the end of the cigarette.
  • the cigarette that results has an increased quantity of highly-flavoured tobacco in the end and a concentration of highly-flavoured tobacco to one side.
  • the increased quantity of highly-flavoured tobacco in the lighting end increases the initial flavour impact to the smoker, while the strip of highly-flavoured tobacco to the side increases the overall flavour without increasing the level of tar in the smoke to the same extent.
  • the effect also permits tar to be reduced but at a lesser sacrifice of flavour.
  • One significant advantage of the cigarette of the invention is that it can be produced on existing cigarette-making equipment without any hardware change and the only difference being the necessity to feed two tobacco blends to the hopper in place of one, and yet there can be produced a cigarette having significantly improved smoking characteristics.
  • the length of the dense end may be increased, for example, by increasing the peripheral length of the notch in the trimming wheels.
  • the quantity of flavour components in the smoke tends to increase as the cigarette is smoked, so that the last puffs usually contain approximately three times the amount of flavour components than the first puff. It is possible to vary the cross-sectional relative proportions of tobacco in the layers in the filler rod along the length of the cigarette, so as to provide a more uniform distribution of smoking characteristics along the length of the cigarette.
  • the cigarette sculpturing techniques described herein may also be combined with the linear layering techniques described in our aforementioned U.S. Patent No. 4,793,367. In such a combination, both sides of the cigarette may be trimmed to provide complimentarily-arranged sides of the cigarette.
  • the filler rod can be further modified to provide a more uniform distribution of the flavour component.
  • the lobes conveniently can be shaped in order to vary the amount of tobacco trimmed as the filler rod moves past the cutter. In this way, the quantity of the highly-flavoured tobacco can be shaped as a function of distance along the finished cigarette, and thereby the quantity of highly-flavoured tobacco along the length of the cigarette is controlled.
  • tobacco lamina blends with differing flavour-to-tar ratios can be achieved by selecting tobacco from different parts of a tobacco plant. Generally, leaves from the upper part of the tobacco plant have a higher flavour/tar ratio than leaves from the lower part of the tobacco plant. In blending the tobacco for inclusion in the cigarette, the higher flavour/tar ratio tobacco normally included in the blend is maintained as a separate blend, although some of such higher flavoured tobacco is present in the lower flavour/tar ratio blend by the recycle of trimmed tobacco, as described above.
  • the present invention provides a novel arrangement of tobacco in a cigarette which enables considerable versatility and uniformity of smoking characteristics to be achieved.
  • the present invention also provides a method of forming such cigarettes by simple yet effective modification of existing cigarette manufacturing operations.
