Suitable natural tobacco leaf materials include tobacco lamina, tobacco stem materials and tobacco stalk material. The natural tobacco leaf materials used because the second tobacco material might include any type of tobacco leaf, including for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mix thereof. A tobacco minimize filler based on the present invention includes a first tobacco material minimize in accordance with a primary minimize specification, whereby the primary reduce specification sets no much less than predetermined first minimize width and first cut size. The time period “filling energy” is used to explain the volume of area taken up by a given weight or mass of a tobacco material. The larger the filling power of a tobacco materials, the decrease the burden of the fabric required to fill a tobacco rod of standard dimensions.
The yield of flat rolled stem which can be used immediately as filler is increased, and the average stem size and thus the common size of cut filler from stem is elevated. A tobacco reduce filler according to any one of the previous claims having a filling energy of at least three.5 cubic centimetres per gram at a reference moisture value Filling cut tobacco of 12.5 % oven volatiles. Accordingly, tobacco particles have been prepared from the identical sheet of reconstituted tobacco based on the cut specification illustrated in Figure 12, wherein the reduce width SCW1 is of zero.9 millimetres, the reduce length CL1 is of 4.94 millimetres and the global width CW1 is of 12.50 millimetres.
Further, the second Y-shaped structure contains a second branching node from which an oblong construction branches off. In the embodiment of Figure 1 1 , the minimize strip includes a primary Y-shaped construction together with a first branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped structure includes a second branching node from which a third Y-shaped construction branches off.
A tobacco reduce filler based on claim 1 or 2, whereby the primary tobacco materials is a pre- processed tobacco materials. In a 3rd experiment, the minimize specification no. 10 was barely modified with a view to bettering the resistance of the particles to the stresses involved by the cigarette-making course of. In particular, there was concern that during the cigarette-making process the tobacco particle would be uncovered to high tensions and frictions which could cause tobacco pipe particles prepared in accordance with the reduce specification no. 10 to interrupt. This may have reduced the profit coming from the V-shape and shown by the CCV measurements described above. Figure 13 depicts a schematic view of an equipment for forming a tobacco cut filler in accordance with the present invention. Figures depict a quantity of examples of particularly shapes into which tobacco materials for forming a minimize filler in accordance with the current invention may be minimize.
Should one such particle break at a location within the central V-shaped portion, the 2 resulting components of the particles would nonetheless be effectively V-shaped. The highest CCV values have been obtained for reduce specification no. three, which considerably corresponds to particles having a Y-shape. However, it was discovered that when particles were produced from the same sheet of reconstituted tobacco in accordance with cut specification no. 3 are produced, a significant fraction of the tobacco material 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 three were measured. Tobacco cut fillers in accordance with the present invention may be ready by a technique comprising providing a primary tobacco material and cutting the first tobacco material in accordance with a primary minimize specification setting a minimum of predetermined first minimize width and first reduce size. Tobacco reduce filler in accordance with the current invention may be incorporated into a big selection of smoking articles.
Even more preferably, first tobacco material is shredded into strips having a minimize size of a minimum of about 15 mm. In addition, or in its place, the primary tobacco material is preferably shredded into strips having a cut size of less than about 60 mm. More ideally, the first tobacco materials is shredded into strips having a cut size of lower than about 50 mm. Even extra preferably, the primary tobacco material is shredded into strips having a cut size of less than about forty mm. In preferred embodiments, the primary tobacco material is shredded into strips having a cut length from about 5 mm to about 60 mm. The time period “sectional minimize width” is used in the current specification to explain the side- to-side width of 1 such portion of a reduce strip of tobacco material.
