According to a facet of the present invention, there’s provided a tobacco cut filler comprising a first tobacco material minimize in accordance with a primary cut specification, whereby the first cut specification sets at least predetermined first cut width and first reduce size. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A process for making ready tobacco stem for tobacco pipe use as filler for a smoking article includes classifying the green tobacco stem by diameter to provide a plurality of stem grades and rolling every grade separately. Each grade is rolled underneath rolling conditions optimized for that grade including rolling the grade by way of the nip between rollers with the nip dimension being adjusted for every grade in order to realize a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted earlier than the rolling.
A tobacco cut filler based on declare 1 or 2, wherein the first tobacco materials is a pre- processed tobacco material. In a third experiment, the minimize 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 particular, there was concern that in the course of the cigarette-making course of the tobacco particle can be exposed to high tensions and frictions which could cause particles prepared in accordance with the minimize specification no. 10 to break. This might have lowered the benefit coming from the V-shape and proven by the CCV measurements described above. Figure thirteen depicts a schematic view of an equipment for forming a tobacco reduce filler in accordance with the present invention. Figures depict several examples of notably shapes into which tobacco material for forming a cut filler in accordance with the current invention could additionally be cut.
Even more ideally, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of at least about 0.2 mm. In addition, or in its place, the primary tobacco materials is ideally shredded into strips from a sheet materials having a thickness of lower than about 1 mm. More ideally Fashion tobacco pipe, the primary tobacco material is shredded into strips from a sheet material having a thickness of less than about 0.95 mm. Even more preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of less than about 0.eighty five mm.
In addition, a second couple of blends was used, that contained 70 p.c by weight of natural tobacco particles and 30 % by weight of reconstituted tobacco particles cut in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the reduce width of an individual minimize strip is taken on the level along the length of the strip that yields the biggest cross-sectional space. Further, the filling energy of the shredded first tobacco materials could be maximised by choosing an acceptable first cut specification. This ends in an improved filling power of the cut filler as a complete, significantly when the first tobacco materials is blended with no less than one other tobacco material.
Alternative methods for the manufacture of reconstituted tobacco sheets are also identified to the expert person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to discuss with a web, preferably with substantially uniform thickness, that might be produced by the rolling or casting of an aqueous slurry or pulp shaped from tobacco particles by one of a number of strategies identified within the artwork. Suitable by-products include tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced during the manufacturing course of.
Should one such particle break at a location within the central V-shaped portion, the 2 ensuing components of the particles would nonetheless be successfully V-shaped. The highest CCV values were obtained for reduce specification no. three, which considerably corresponds to particles having a Y-shape. However, it was discovered that when particles have been produced from the identical sheet of reconstituted tobacco in accordance with cut specification no. three 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 within Filling cut tobacco the following Table 3 have been measured. Tobacco cut fillers according to the current invention could also be prepared by a way comprising offering a first tobacco material and chopping the primary tobacco materials in accordance with a first reduce specification setting at least predetermined first cut width and first reduce length. Tobacco reduce filler in accordance with the current invention may be incorporated into a variety of smoking articles.
