In turn, the third Y-shaped construction contains a 3rd branching node from which an oblong construction branches off. In the embodiments of both Figures 9 and 1 1 the sectional reduce width inside all the structures forming the minimize strips is substantially constant. By means of instance , in a Y-shaped strip it is possible to determine a first strip portion extending alongside a primary course and a second and third strip parts extending from the primary strip parts alongside diverging instructions, so that they kind an angle.
Even more ideally, first tobacco materials is shredded into strips having a cut length of no much less than about 15 mm. In addition, or instead, the first tobacco material is preferably shredded into strips having a minimize size of less than about 60 mm. More ideally, the primary tobacco materials is shredded into strips having a reduce size of less than about 50 mm. Even more preferably, the primary tobacco materials is shredded into strips having a minimize length of less than about 40 mm. In most well-liked embodiments, the primary tobacco material is shredded into strips having a minimize length from about 5 mm to about 60 mm. The time period “sectional cut width” is used within the present specification to describe the side- to-side width of one such portion of a cut strip of tobacco materials.
Within a cut strip of tobacco materials, the sectional reduce width will be the considerably identical for all the strip portions. While this could be preferable, the sectional reduce width may also vary from one strip portion to a different. Typically, prior to being reduce, a tobacco material could endure other mechanical operations, similar to rolling or extrusion.
Suitable pure tobacco leaf supplies embody tobacco lamina, tobacco stem material and tobacco stalk materials. The natural tobacco leaf material used as the second tobacco materials might embody any sort of tobacco leaf, including for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco minimize filler based on the present invention includes a first tobacco material reduce in accordance with a first Filling cut tobacco minimize specification, whereby the first minimize specification sets a minimal of predetermined first cut width and first minimize size. The time period “filling energy” is used to describe the volume of space taken up by a given weight or mass of a tobacco material. The greater the filling power of a tobacco material, the decrease the load of the material required to fill a tobacco rod of normal dimensions.
More preferably, the first tobacco materials is shredded into strips having a reduce width of less than about zero.95 mm. Even extra ideally, the first tobacco materials is shredded into strips having a minimize width of lower than about zero.9 mm. In most popular embodiments, the first tobacco material is shredded into strips having a cut width from about 0.2 mm to about 1 mm. Preferably, the second tobacco material is a pure tobacco leaf materials.
By way of instance, tobacco stems may be ground to a fine powder and then mixed with tobacco dust, guar gum, and water to form an aqueous slurry. This aqueous slurry may be forged and dried to kind a reconstituted tobacco sheet. As an alternative, suitable tobacco supplies may be blended 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 apparatus 30 for the manufacture of a tobacco reduce filler in accordance with the present invention. A web 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding gadget 36.
Conventionally, reduce filler tobacco products for smoking articles are fashioned predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf throughout a threshing course of. Much of the stem portion that continues to be after the lamina has been removed and separated just isn’t used. However, it isn’t unusual to add some tobacco stems back into the minimize filler along with the lamina.
A tobacco cut filler in accordance with declare 1 or 2, whereby the primary tobacco material is a pre- processed tobacco material. In a 3rd experiment, the cut specification no. 10 was barely modified with a view to improving the resistance of the particles to the stresses involved by the cigarette-making course of. In particular, there was concern that through the cigarette-making course of the tobacco particle would be exposed to high tensions and frictions which could cause particles prepared in accordance with the reduce specification no. 10 to break. This might have lowered the profit coming from the V-shape and shown 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 a quantity of examples of notably shapes into which tobacco material for forming a reduce filler in accordance with the present invention may be cut.
