Suitable natural tobacco leaf supplies embody tobacco lamina, tobacco stem materials and tobacco stalk material. The natural tobacco leaf material used because the second tobacco materials might embody any type of tobacco leaf, including for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco minimize filler in accordance with the present invention contains a first tobacco material reduce in accordance with a first cut specification, wherein the first cut specification units at least predetermined first cut width and first cut length. The time period “filling energy” is used to describe the amount of space taken up by a given weight or mass of a tobacco materials. The larger the filling energy of a tobacco material, the decrease the load of the material required to fill a tobacco rod of ordinary dimensions.
Even extra preferably, first tobacco materials is shredded into strips having a cut size of no less than about 15 mm. In addition, or as an alternative, the first tobacco material is ideally shredded into strips having a minimize size of lower than about 60 mm. More preferably, the primary tobacco materials is shredded into strips having a reduce size of lower than about 50 mm. Even more ideally, the primary tobacco pipe tobacco materials is shredded into strips having a reduce length of lower than about forty mm. In most popular embodiments, the primary tobacco materials is shredded into strips having a minimize size from about 5 mm to about 60 mm. The term “sectional cut width” is used in the present specification to explain the side- to-side width of 1 such portion of a minimize strip of tobacco material.
Within a cut strip of tobacco material, the sectional cut width could be the substantially same for all of the strip parts. While this can be preferable, the sectional minimize width can also Filling cut tobacco vary from one strip portion to another. Typically, previous to being reduce, a tobacco materials might undergo different mechanical operations, similar to rolling or extrusion.
For instance, a bimodal distribution could correspond effectively to two teams of minimize strips having totally different average minimize lengths , one group being larger than the opposite. Preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of at least about 0.05 mm. More ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness of no much less than about zero.1 mm.
Should one such particle break at a location in the central V-shaped portion, the 2 ensuing elements of the particles would nonetheless be effectively V-shaped. The highest CCV values have been obtained for cut specification no. three, which considerably corresponds to particles having a Y-shape. However, it was found that when particles have been produced from the identical sheet of reconstituted tobacco according to reduce specification no. 3 are produced, a big 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 were measured. Tobacco reduce fillers according to the present invention could additionally be ready by a technique comprising offering a first tobacco material and cutting the first tobacco materials in accordance with a primary reduce specification setting no less than predetermined first minimize width and first minimize size. Tobacco minimize filler in accordance with the current invention could also be incorporated into quite so much of smoking articles.
