In addition, a second couple of blends was used, that contained 70 percent by weight of natural tobacco particles and 30 percent by weight of reconstituted tobacco particles minimize in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the reduce width of an individual cut strip is taken on the level alongside the size of the strip that yields the biggest cross-sectional area. Further, the filling power Fashion tobacco pipe of the shredded first tobacco materials could be maximised by choosing an appropriate first cut specification. This leads to an improved filling power of the reduce filler as a whole, significantly when the primary tobacco material is blended with no less than another tobacco materials.
Should one such particle break at a location in the central V-shaped portion, the two resulting elements of the particles would nonetheless be successfully V-shaped. The highest CCV values have been obtained for reduce specification no. 3, which considerably corresponds to particles having a Y-shape. However, it was found that when particles were produced from the identical sheet of reconstituted tobacco based on cut specification no. three are produced, a major 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 had been measured. Tobacco minimize fillers based on the present invention may be prepared by a technique comprising providing a primary tobacco materials and slicing the first tobacco material in accordance with a first reduce specification setting at least predetermined first cut width and first cut length. Tobacco minimize filler in accordance with the current invention could also be integrated into a selection of smoking articles.
In most popular embodiments, the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Even extra preferably, the first tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.1 mm to about 0.3 mm, most preferably from a sheet materials having a thickness of about 0.2 mm. A tobacco minimize filler based on any one of claims 1 to 9, whereby the primary tobacco pipe tobacco materials is shredded into strips every comprising a minimal of a first strip construction comprising a branching node from which an additional strip structure branches off, forming an angle with the first strip structure. Figures 10 and 12 present two examples of cut strips including a quantity of V-shaped structure. Each V construction includes two substantially straight components forming an angle.
More preferably, the primary tobacco materials is shredded into strips having a reduce width of no much less than about 0.25 mm. Even extra preferably, the first tobacco material is shredded into strips having a minimize width of no less than about 0.three mm. In addition, or instead, the primary tobacco materials is ideally shredded into strips having a cut width of lower than about 1 mm.
The time period “minimize specification” is used all through the specification to refer to the varied geometric parameters characterising the strips obtained by subjecting a tobacco materials to a slicing operation. Thus, in accordance to a given “reduce specification”, a tobacco material shall be reduce or shredded into strips having a predetermined minimize width, cut length, reduce form and so forth. Further, it will be desirable to offer one such improved process that allows for a better management of the shape, measurement and properties of the reconstituted tobacco matter forming a half of the reduce filler. At the same time, it would be fascinating to supply one such process that doesn’t require any main modification of the conventional apparatus and amenities used within the major treatment of tobacco.
Suitable pure tobacco leaf supplies include tobacco lamina, tobacco stem material and tobacco stalk materials. The natural tobacco leaf materials used as the second tobacco material could embrace any type of tobacco leaf, including for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco cut filler in accordance with the present invention contains a first tobacco materials cut in accordance with a first reduce specification, wherein the primary cut specification units a minimal of predetermined first cut width and first reduce size. The term “filling energy” is used to explain the volume of area taken up by a given weight or mass of a tobacco material. The larger the filling power of a tobacco material, the decrease the load of the material required to fill a tobacco rod of standard dimensions.
