Suitable natural tobacco leaf materials embrace tobacco lamina, tobacco stem material and tobacco stalk material. The pure tobacco leaf materials used as the second tobacco material could embody any kind 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 according to the current invention comprises a primary tobacco material reduce in accordance with a primary minimize specification, whereby the primary minimize specification units at least predetermined first reduce width and first cut length. The term “filling power” is used to describe the amount of space taken up by a given weight or mass of a tobacco material. The larger the filling power of a tobacco materials, the decrease the burden of the material required to fill a tobacco rod of ordinary dimensions.
In most popular embodiments, the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about 0.05 mm to about 1 mm. Even more preferably, the first tobacco materials is shredded into strips from a sheet material having a thickness from about zero.1 mm to about 0.three mm, most preferably from a sheet material having a thickness of about 0.2 mm. A tobacco reduce filler based on any one of claims 1 to 9, whereby the primary tobacco pipe tobacco materials is shredded into strips every comprising no less than a primary strip construction comprising a branching node from which an extra strip structure branches off, forming an angle with the first strip structure. Figures 10 and 12 show two examples of cut strips including one or more V-shaped structure. Each V construction contains two substantially straight components forming an angle.
According to a facet of the present invention, there is provided a tobacco reduce filler comprising a first tobacco materials cut in accordance with a primary reduce specification, wherein the primary reduce specification sets a minimum of 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 preparing tobacco stem for use as filler for a smoking article includes classifying the green tobacco stem by diameter to supply a plurality of stem grades and rolling each 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 size being adjusted for each grade so as to realize a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted before the rolling.
Should one such particle break at a location within the central V-shaped portion, the 2 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 discovered that when particles had been produced from the identical sheet of reconstituted tobacco in accordance with reduce specification no. 3 are produced, a major fraction of the tobacco material 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 reduce fillers based on the current invention may be prepared by a way comprising offering a first tobacco materials and cutting the primary tobacco material in accordance with a first reduce specification setting a minimal of predetermined first cut width and first minimize length. Tobacco reduce filler in accordance with the current invention may be incorporated into a wide selection of smoking articles.
More ideally, the primary tobacco material is shredded into strips having a minimize width of a minimum of about zero.25 mm. Even extra preferably, the primary tobacco material is shredded into strips having a reduce width of a minimum Fashion tobacco pipe of about zero.3 mm. In addition, or instead, the primary tobacco materials is ideally shredded into strips having a reduce width of less than about 1 mm.
