For instance, a bimodal distribution might correspond successfully to two groups of reduce strips having totally different average reduce lengths , one group being larger than the opposite. Preferably, the first tobacco material is shredded into strips from a sheet materials Fashion tobacco pipe having a thickness of a minimum of about zero.05 mm. More ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness of at least about zero.1 mm.
Even more preferably, the first tobacco material is shredded into strips from a sheet materials having a thickness of at least about zero.2 mm. In addition, or as an alternative, the first tobacco material is preferably shredded into strips from a sheet material having a thickness of less than about 1 mm. More preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of less than about 0.95 mm. Even more preferably, the primary tobacco material is shredded into strips from a sheet material having a thickness of lower than about zero.85 mm.
According to an aspect of the current invention, there is offered a tobacco minimize filler comprising a primary tobacco material reduce in accordance with a first minimize specification, whereby the primary cut specification units no less than predetermined first reduce width and first cut length. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A process for getting ready tobacco stem for use as filler for a smoking article includes classifying the green tobacco stem by diameter to supply a plurality of stem grades and rolling each grade individually. Each grade is rolled underneath rolling conditions optimized for that grade including rolling the grade through the nip between rollers with the nip measurement being adjusted for each grade so as to realize a uniform rolled stem thickness and the oven volatiles content material of the stem being adjusted earlier than the rolling.
The yield of flat rolled stem which may be used instantly as filler is elevated, and the average stem size and thus the common size of reduce filler from stem is increased. A tobacco minimize filler according to any one of the previous claims having a filling energy of at least 3.5 cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. Accordingly, tobacco particles have been prepared from the identical sheet of reconstituted tobacco in accordance with the cut specification illustrated in Figure 12, wherein the cut width SCW1 is of zero.9 millimetres, the minimize size CL1 is of 4.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
Even more preferably, first tobacco materials is shredded into strips having a minimize size of no much less than about 15 mm. In addition, or in its place, the first tobacco materials is ideally shredded into strips having a minimize size of lower than about 60 mm. More ideally, the first tobacco materials is shredded into strips having a minimize size of less than about 50 mm. Even more preferably, the first tobacco material is shredded into strips having a minimize size of lower than about forty mm. In most well-liked embodiments, the primary tobacco material 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 current specification to describe the side- to-side width of 1 such portion of a minimize strip of tobacco material.
Should one such particle break at a location in the central V-shaped portion, the 2 ensuing components of the particles would still be effectively V-shaped. The highest CCV values have been obtained for minimize specification no. three, which substantially corresponds to particles having a Y-shape. However, it was found that when particles were produced from the same sheet of reconstituted tobacco in accordance with cut 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 three have been measured. Tobacco cut fillers based on the present invention may be ready by a method comprising offering a primary tobacco materials and chopping the first tobacco materials in accordance with a primary minimize specification setting at least predetermined first reduce width and first cut size. Tobacco minimize filler in accordance with the present invention could also be included into a selection of smoking articles.
In some embodiments, tobacco minimize filler according to the invention may be used in the tobacco rod of a combustible smoking article, similar to a filter cigarette, cigarillo or cigar. Alternatively, the cut filler could also be used to offer the tobacco aerosol producing substrate in a distillation primarily based smoking article, or an electrically heated smoking system. Alternatively, the minimize filler could additionally be used as a roll-your-own or make-your-own product, or unfastened tobacco product to be used in a pipe.
A tobacco reduce filler according to declare 1 or 2, wherein the primary tobacco material is a pre- processed tobacco materials. In a third experiment, the reduce specification no. 10 was slightly modified with a view to enhancing the resistance of the particles to the stresses involved by the cigarette-making process. In explicit, there was concern that through the cigarette-making course of the tobacco particle can be exposed to high tensions and frictions which might trigger particles ready in accordance with the reduce specification no. 10 to break. This might have reduced 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 current invention. Figures depict several examples of particularly shapes into which tobacco material for forming a reduce filler in accordance with the current invention may be minimize.
Further, the second Y-shaped construction comprises a second branching node from which an oblong structure branches off. In the embodiment of Figure 1 1 , the minimize strip comprises a primary Y-shaped construction together with a first branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped structure comprises a second branching node from which a 3rd Y-shaped construction branches off.
