For instance, a bimodal distribution may correspond effectively to 2 groups of cut strips having different common reduce lengths , one group being larger than the opposite. Preferably, the primary tobacco materials is shredded into strips from a sheet material Fashion tobacco pipe having a thickness of a minimum of about zero.05 mm. More ideally, the first tobacco material is shredded into strips from a sheet materials having a thickness of a minimal of about zero.1 mm.
The yield of flat rolled stem which can be used immediately as filler is increased, and the common stem length and thus the typical length of reduce filler from stem is increased. A tobacco reduce filler according to any one of the preceding claims having a filling energy of no much less than 3.5 cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. Accordingly, tobacco particles had been prepared from the same sheet of reconstituted tobacco in accordance with the minimize specification illustrated in Figure 12, whereby the reduce width SCW1 is of zero.9 millimetres, the minimize length CL1 is of four.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
The term “cut specification” is used all through the specification to refer to the various geometric parameters characterising the strips obtained by subjecting a tobacco materials to a cutting operation. Thus, in accordance to a given “minimize specification”, a tobacco material shall be cut or shredded into strips having a predetermined reduce width, reduce size, minimize shape and so forth. Further, it would be fascinating to supply one such improved course of that allows for a better control of the shape, size and properties of the reconstituted tobacco matter forming part of the cut filler. At the same time, it will be desirable to supply one such course of that does not require any major modification of the standard equipment and amenities used within the primary therapy of tobacco.
According to an aspect of the present invention, there is provided a tobacco reduce filler comprising a primary tobacco materials minimize in accordance with a first reduce specification, whereby the first cut specification sets at least predetermined first minimize width and first minimize length. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A course of for getting ready tobacco stem to be tobacco pipe used as filler for a smoking article includes classifying the green tobacco stem by diameter to offer a plurality of stem grades and rolling each grade individually. Each grade is rolled underneath rolling situations optimized for that grade including rolling the grade by way of the nip between rollers with the nip measurement being adjusted for every grade so as to achieve a uniform rolled stem thickness and the oven volatiles content material of the stem being adjusted before the rolling.
In the embodiment of Figure 10, the two straight parts are substantially perpendicular. The minimize strip of Figure 12 could additionally be thought to be comprising three V-shaped structures of the type illustrated in Figure 1 , wherein adjoining V-shaped buildings are related by the ends of respective straight elements. In the embodiments of both Figures 10 and 12 the sectional minimize width within all of the buildings forming the reduce strips is substantially fixed. A tobacco cut filler according to any one of many previous claims, whereby the reduce length distribution among the many minimize strips of the primary tobacco material is preferably unimodal. By means of example, the reduce strip of Figure 9 comprises a first Y-shaped structure together with a primary branching node from which a second Y-shaped construction branches off.
In most popular embodiments, the primary tobacco material is shredded into strips from a sheet material 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 0.1 mm to about 0.3 mm, most ideally from a sheet materials having a thickness of about zero.2 mm. A tobacco cut filler in accordance with any considered one of claims 1 to 9, wherein the first tobacco material is shredded into strips every comprising a minimum of a first strip construction comprising a branching node from which a further strip construction branches off, forming an angle with the primary strip structure. Figures 10 and 12 present two examples of cut strips including a quantity of V-shaped structure. Each V construction includes two considerably straight elements forming an angle.
Further, the second Y-shaped structure includes a second branching node from which an oblong structure branches off. In the embodiment of Figure 1 1 , the minimize strip comprises a primary Y-shaped construction including a primary branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped structure contains a second branching node from which a third Y-shaped construction branches off.
In flip, the third Y-shaped structure comprises a 3rd branching node from which a rectangular structure branches off. In the embodiments of each Figures 9 and 1 1 the sectional reduce width within all the constructions forming the reduce strips is substantially constant. By way of instance, in a Y-shaped strip it is attainable to identify a primary strip portion extending alongside a primary direction and a second and third strip portions extending from the first strip parts alongside diverging instructions, so that they type an angle.
In practice, one such minimize strip could also be described as approximately wave-shaped or zigzag-shaped. Accordingly, geometric parameters corresponding to the peak amplitude, peak-to-peak amplitude, interval of a sine wave may be used to explain the shape of 1 such minimize strips. A tobacco minimize filler comprises a first tobacco materials cut in accordance with a primary reduce specification, whereby the first reduce specification units a minimal of predetermined first minimize width and first reduce size. A tobacco minimize filler in accordance with any one of the preceding claims, whereby the primary tobacco material is shredded into strips having a minimize width from about 0.2 mm to about 1 mm.
Blending the reduce first tobacco material and the cut second tobacco material.
