Within a cut strip of tobacco materials, the sectional reduce width could be the considerably same for all the strip parts. While this might be preferable, the sectional minimize width may range from one strip portion to a different. Typically, previous to being minimize, a tobacco material could undergo other mechanical operations, corresponding to rolling or extrusion.
Further, the second Y-shaped structure comprises a second branching node from which a rectangular construction branches off. In the embodiment of Figure 1 1 , the minimize strip contains a first Y-shaped construction together Filling cut tobacco with a first branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped construction includes a second branching node from which a third Y-shaped structure branches off.
According to a facet of the present invention, there could be provided a tobacco reduce filler comprising a first tobacco material cut in accordance with a first cut specification, wherein the first reduce specification sets no much less than predetermined first cut width and first reduce length. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A course of for making ready tobacco stem to be used as filler for a smoking article contains 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 including rolling the grade via the nip between rollers with the nip measurement being adjusted for each grade so as to achieve a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted earlier than the rolling.
Should one such particle break at a location in the central V-shaped portion, the two ensuing components of the particles would nonetheless be successfully V-shaped. The highest CCV values were obtained for reduce specification no. three, which substantially corresponds to particles having a Y-shape. However, it was discovered that when particles have been produced from the identical sheet of reconstituted tobacco based on 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 in the following Table 3 were measured. Tobacco minimize fillers in accordance with the present invention could additionally be ready by a way comprising offering a primary tobacco materials and chopping the first tobacco material in accordance with a first reduce specification setting no much less than predetermined first reduce width and first reduce length. Tobacco reduce filler in accordance with the present invention could additionally be incorporated into a wide selection of smoking articles.
By means of instance, tobacco stems may be ground to a fine powder and then blended with tobacco dust, guar gum, and water to kind an aqueous slurry. This aqueous slurry could additionally be forged and dried to form a reconstituted tobacco sheet. As an alternate, appropriate tobacco materials could additionally be mixed in an agitated tank with water to obtain a pulp. This web is fed onwards to a press, where the surplus water is squeezed out of the web. Figure 13 illustrates an equipment 30 for the manufacture of a tobacco reduce filler in accordance with the present invention. A net 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding gadget 36.
More ideally, the primary tobacco materials is shredded into strips having a minimize width of less than about zero.ninety five mm. Even more preferably, the first tobacco materials is shredded into strips having a minimize width of less than about 0.9 mm. In preferred embodiments, the primary tobacco materials is shredded into strips having a cut width from about zero.2 mm to about 1 mm. Preferably, the second tobacco material is a pure tobacco leaf materials.
