For example, a bimodal distribution may correspond effectively to 2 groups of cut strips having totally different average cut 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 a minimal of about zero.05 mm. More ideally, the first tobacco materials is shredded into strips from a sheet material having a thickness of a minimal of about 0.1 mm.
A tobacco reduce filler based on declare 1 or 2, wherein the primary tobacco material is a pre- processed tobacco materials. In a 3rd experiment, the cut specification no. 10 was barely modified with a view to bettering the resistance of the particles to the stresses concerned by the cigarette-making course of. In particular, there was concern that in the course of the cigarette-making course of the tobacco particle could be uncovered to high tensions and frictions which Fashion tobacco pipe might cause particles prepared in accordance with the reduce specification no. 10 to interrupt. This might have decreased the benefit 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 a quantity of examples of particularly shapes into which tobacco material for forming a minimize filler in accordance with the current invention could additionally be reduce.
According to an aspect of the current invention, there might be provided a tobacco cut filler comprising a primary tobacco material cut in accordance with a first cut specification, whereby the first cut specification sets no less than predetermined first reduce width and first reduce size. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A course of for preparing tobacco stem for use as filler for a smoking article consists of classifying the green tobacco stem by diameter to offer a plurality of stem grades and rolling every grade individually. Each grade is rolled beneath rolling circumstances optimized for that grade together with rolling the grade via the nip between rollers with the nip dimension being adjusted for each grade in order to achieve a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted before the rolling.
More ideally, the primary tobacco material is shredded into strips having a reduce width of lower than about zero.ninety five mm. Even more ideally, the primary tobacco material is shredded into strips having a reduce width of lower tobacco pipe than about 0.9 mm. In preferred embodiments, the first tobacco material 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 materials.
Should one such particle break at a location within the central V-shaped portion, the 2 ensuing components of the particles would nonetheless be effectively V-shaped. The highest CCV values were obtained for minimize specification no. 3, which considerably corresponds to particles having a Y-shape. However, it was discovered that when particles have been produced from the same sheet of reconstituted tobacco in accordance with cut specification no. 3 are produced, a significant 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 in the following Table 3 had been measured. Tobacco cut fillers based on the current invention may be ready by a technique comprising offering a primary tobacco material and chopping the primary tobacco material in accordance with a first minimize specification setting a minimum of predetermined first cut width and first reduce size. Tobacco reduce filler in accordance with the current invention may be included into a big selection of smoking articles.
Further, the second Y-shaped construction contains a second branching node from which an oblong construction branches off. In the embodiment of Figure 1 1 , the minimize strip comprises a first Y-shaped construction together with a primary branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped construction contains a second branching node from which a 3rd Y-shaped construction branches off.
