By contrast, in a multimodal distribution, the likelihood mass function has a quantity of maxima, which signifies that among the cut strips of the primary tobacco material there are a quantity of values of reduce length that happen most often. In the context of the present specification, a distribution having multiple local maxima is thought tobacco pipe to be multimodal. It shall be appreciated that the different modes in a multimodal distribution can also have completely different frequencies, such that, among the many minimize strips of the first tobacco material, one modal worth of reduce length will occur extra regularly than one other modal worth.
In addition, a second couple of blends was used, that contained 70 p.c by weight of pure tobacco particles and 30 % by weight of reconstituted tobacco particles reduce in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the reduce width of an individual cut strip is taken at the level along the size of the strip that yields the largest cross-sectional space. Further, the filling power of the shredded first tobacco materials can be maximised by choosing an appropriate first minimize specification. This results in an improved filling energy of the minimize filler as an entire, significantly when the first tobacco materials is mixed with a minimum of one other tobacco materials.
A tobacco minimize filler based on claim 1 or 2, wherein the primary tobacco material is a pre- processed tobacco material. In a 3rd experiment, the reduce specification no. 10 was slightly modified with a view to improving the resistance of the particles to the stresses concerned by the cigarette-making course of. In specific, there was concern that in the course of the cigarette-making course of the tobacco particle can be uncovered to high tensions and frictions which might trigger particles ready in accordance with the cut specification no. 10 to break. This could have lowered the profit coming from the V-shape and proven by the CCV measurements described above. Figure 13 depicts a schematic view of an equipment for forming a tobacco minimize filler in accordance with the present invention. Figures depict a quantity of examples of particularly shapes into which tobacco material for forming a minimize filler in accordance with the current invention may be reduce.
Should one such particle break at a location within the central V-shaped portion, the 2 resulting elements of the particles would nonetheless be successfully V-shaped. The highest CCV values had been obtained for cut specification no. three, which considerably corresponds to particles having a Y-shape. However, it was discovered that when particles were produced from the identical sheet of reconstituted tobacco in accordance with minimize specification no. three 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 in the Fashion tobacco pipe following Table three were measured. Tobacco cut fillers based on the current invention may be prepared by a way comprising offering a primary tobacco material and cutting the first tobacco material in accordance with a first minimize specification setting no less than predetermined first reduce width and first reduce size. Tobacco minimize filler in accordance with the present invention may be integrated into quite lots of smoking articles.
In most well-liked embodiments, the primary tobacco material is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even more preferably, the primary tobacco material is shredded into strips from a sheet materials having a thickness from about 0.1 mm to about 0.three mm, most ideally from a sheet material having a thickness of about zero.2 mm. A tobacco cut filler according to any certainly one of claims 1 to 9, wherein the first tobacco materials is shredded into strips every comprising at least a primary strip structure comprising a branching node from which a further strip construction branches off, forming an angle with the primary strip structure. Figures 10 and 12 show two examples of minimize strips including one or more V-shaped structure. Each V construction contains two substantially straight elements forming an angle.
More preferably, the primary tobacco material is shredded into strips having a minimize width of lower than about zero.ninety five mm. Even extra preferably, the primary tobacco material is shredded into strips having a cut width of less than about 0.9 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 pure tobacco leaf material.
