More preferably, the primary tobacco material is shredded into strips having a minimize width of less than about 0.95 mm. Even extra preferably, the primary tobacco material is shredded into strips having a reduce width of less tobacco pipe than about zero.9 mm. In preferred embodiments, the first tobacco material is shredded into strips having a minimize width from about 0.2 mm to about 1 mm. Preferably, the second tobacco material is a natural tobacco leaf material.
According to a side of the current invention, there’s offered a tobacco minimize filler comprising a primary tobacco materials reduce in accordance with a first minimize specification, whereby the primary reduce specification sets at least predetermined first cut width and first cut size. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A process for getting ready tobacco stem to be used as filler for a smoking article includes classifying the green tobacco stem by diameter to supply a plurality of stem grades and rolling every grade individually. Each grade is rolled beneath rolling conditions optimized for that grade including rolling the grade via the nip between rollers with the nip dimension being adjusted for each grade so as to achieve a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted before the rolling.
The yield of flat rolled stem which can be used instantly as filler is increased, and the common stem length and thus the common length of cut filler from stem is elevated. A tobacco cut filler in accordance with any one of many previous claims having a filling energy of a minimal of three.5 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles. Accordingly, tobacco particles were ready from the same sheet of reconstituted tobacco according to the cut specification illustrated in Figure 12, whereby the cut width SCW1 is of 0.9 millimetres, the reduce size CL1 is of four.ninety four millimetres and the global width CW1 is of 12.50 millimetres.
Within a cut strip of tobacco material, the sectional minimize width will be the substantially same for all the strip portions. While this can be preferable, the sectional minimize width may differ from one strip portion to another. Typically, previous to being reduce, a tobacco material might undergo different mechanical operations, corresponding to rolling or extrusion.
Even extra preferably, first tobacco material is shredded into strips having a minimize length of no less than about 15 mm. In addition, or instead, the first tobacco material is ideally shredded into strips having a minimize length of less than about 60 mm. More preferably, the first tobacco materials is shredded into strips having a minimize length of lower than about 50 mm. Even more ideally, the first Filling cut tobacco tobacco materials is shredded into strips having a reduce length of lower than about 40 mm. In preferred embodiments, the first tobacco materials is shredded into strips having a reduce size from about 5 mm to about 60 mm. The term “sectional reduce width” is used in the current specification to describe the side- to-side width of one such portion of a cut strip of tobacco material.
Should one such particle break at a location in the central V-shaped portion, the two resulting components of the particles would still 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 same sheet of reconstituted tobacco according to cut specification no. three 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 within the following Table 3 had been measured. Tobacco minimize fillers based on the current invention could additionally be prepared by a technique comprising offering a first tobacco materials and slicing the first tobacco material in accordance with a primary reduce specification setting a minimum of predetermined first minimize width and first cut length. Tobacco reduce filler in accordance with the present invention could additionally be incorporated into a variety of smoking articles.
