Suitable pure tobacco leaf materials embody tobacco lamina, tobacco stem materials and tobacco stalk materials. The pure tobacco leaf materials used because the second tobacco materials could include any kind of tobacco leaf, including for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco reduce filler in accordance with the current invention comprises a primary tobacco material reduce in accordance with a first reduce specification, whereby the primary minimize specification units no much less than predetermined first reduce width and first cut length. The time period “filling power” is used to describe the amount of space taken up by a given weight or mass of a tobacco materials. The greater the filling energy of a tobacco materials, the decrease the burden of the material required to fill a tobacco rod of ordinary dimensions.
Even extra preferably, first tobacco materials is shredded into strips having a reduce length of no less than about 15 mm. In addition, or in its place, the primary tobacco material is preferably shredded into strips having a minimize size of less than about 60 mm. More preferably, the primary tobacco materials is shredded into strips having a minimize length of less than about 50 mm. Even extra preferably, the primary Filling cut tobacco tobacco material is shredded into strips having a cut size of lower than about 40 mm. In preferred embodiments, the first tobacco materials is shredded into strips having a reduce size from about 5 mm to about 60 mm. The time period “sectional cut width” is used in the present specification to explain the side- to-side width of 1 such portion of a reduce strip of tobacco materials.
Should one such particle break at a location in the central V-shaped portion, the two resulting elements of the particles would nonetheless be effectively V-shaped. The highest CCV values were obtained for minimize specification no. 3, which substantially corresponds to particles having a Y-shape. However, it was discovered that when particles had been produced from the same sheet of reconstituted tobacco in accordance with reduce specification no. 3 are produced, a major fraction of the tobacco materials went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed within the following Table 3 had been measured. Tobacco minimize fillers according to the present invention may be ready by a technique comprising offering a first tobacco material and slicing the first tobacco material in accordance with a primary cut specification setting no much less than predetermined first reduce width and first cut size. Tobacco reduce filler in accordance with the present invention may be incorporated into a variety of smoking articles.
For instance, a bimodal distribution might correspond successfully to two teams of cut strips having different average reduce lengths , one group being larger than the opposite. Preferably, the first tobacco material is shredded into strips from a sheet materials having a thickness of at least about zero.05 mm. More ideally, the primary tobacco material is shredded into strips from a sheet materials having a thickness of at least about zero.1 mm.
More ideally, the primary tobacco materials is shredded into strips having a minimize width of less than about 0.ninety five mm. Even more ideally, the primary tobacco materials is shredded into strips having a minimize width of lower than about zero.9 mm. In most popular embodiments, the first tobacco materials is shredded into strips having a reduce width from about 0.2 mm to about 1 mm. Preferably, the second tobacco materials is a natural tobacco leaf material.
