In turn, the third Y-shaped structure contains a third branching node from which a rectangular construction branches off. In the embodiments of each Figures 9 and 1 1 the sectional minimize width inside all of the structures forming the cut strips is considerably fixed. By way of example, in a Y-shaped strip it is attainable to establish a primary strip portion extending alongside a first course and a second and third strip parts extending from the first strip portions along diverging instructions, so that they kind an angle.
More preferably, the reduce filler has a filling power of lower than about 7 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. In some particularly most well-liked embodiments, the reduce filler has a filling energy of from about 3.5 cubic centimetres per gram to about 8 cubic centimetres per gram at a reference moisture worth Filling cut tobacco of 12.5 % oven volatiles. Preferably, the first tobacco material is shredded into strips having a cut size of no less than about 5 mm. More preferably, the primary tobacco material is shredded into strips having a cut size of at least about 10 mm.
Even extra preferably, first tobacco materials is shredded into strips having a reduce length of at least about 15 mm. In addition, or as an alternative, the primary tobacco materials is ideally shredded into strips having a minimize length of lower than about 60 mm. More ideally, the primary tobacco materials is shredded into strips having a cut length of less than about 50 mm. Even more preferably, the first tobacco materials is shredded into strips having a minimize length of lower than about 40 mm. In preferred embodiments, the primary tobacco materials is shredded into strips having a cut size from about 5 mm to about 60 mm. The time period “sectional minimize width” is used in the present specification to describe the side- to-side width of 1 such portion of a minimize strip of tobacco materials.
Suitable natural tobacco leaf supplies embody tobacco lamina, tobacco stem materials and tobacco stalk materials. The natural tobacco leaf material used because the second tobacco materials 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 mix thereof. A tobacco reduce filler based on the present invention contains a primary tobacco materials minimize in accordance with a primary tobacco pipe cut specification, wherein the first cut specification sets at least predetermined first minimize width and first cut length. The term “filling power” is used to explain the quantity of area taken up by a given weight or mass of a tobacco materials. The greater the filling energy of a tobacco material, the lower the load of the material required to fill a tobacco rod of standard dimensions.
In some embodiment, the reduce width distribution among the many reduce strips of the primary tobacco materials is preferably unimodal. In different embodiments, the cut width distribution among the reduce strips of the first tobacco materials could also be multimodal, including in particular bimodal and trimodal. If a distribution has two or more modes, it is typically known as multimodal. Particular examples are bimodal and trimodal distributions, which have two and three modes, respectively. Preferably, the primary tobacco material is shredded into strips having a cut width of at least about 0.2 mm.
In the embodiment of Figure 10, the two straight parts are substantially perpendicular. The minimize strip of Figure 12 may be regarded as comprising three V-shaped constructions of the kind illustrated in Figure 1 , wherein adjoining V-shaped constructions are related by the ends of respective straight elements. In the embodiments of each Figures 10 and 12 the sectional cut width within all the buildings forming the reduce strips is substantially constant. A tobacco cut filler in accordance with any one of many previous claims, wherein the minimize size distribution among the cut strips of the first tobacco material is ideally unimodal. By method of example, the cut strip of Figure 9 contains a first Y-shaped structure including a first branching node from which a second Y-shaped structure branches off.
Before each measurement was taken, tobacco particles cut in accordance with the various reduce specifications had been saved in a conditioned room for twenty-four hours. For every specification, three measurements of the CCV have been taken on the five samples, after which the whole common was calculated and assumed because the effective CCV of the specification. Between repetitions of the measurements, the samples had been prepared by detangling the individual strands, so that any compaction occurred during the previous measurement would have as little affect as potential on the subsequently measured CCV. In some embodiment, the reduce length distribution among the reduce strips of the first tobacco materials is ideally unimodal.
The yield of flat rolled stem which can be used directly as filler is increased, and the average stem length and thus the average length of reduce filler from stem is increased. A tobacco minimize filler in accordance with any one of many previous claims having a filling power of no much less than 3.5 cubic centimetres per gram at a reference moisture worth Fashion tobacco pipe of 12.5 p.c oven volatiles. Accordingly, tobacco particles had been ready from the same sheet of reconstituted tobacco based on the minimize specification illustrated in Figure 12, wherein the reduce width SCW1 is of zero.9 millimetres, the cut size CL1 is of four.ninety four millimetres and the global width CW1 is of 12.50 millimetres.
More preferably, the primary tobacco materials is shredded into strips having a minimize width of a minimum of about zero.25 mm. Even more ideally, the first tobacco material is shredded into strips having a reduce width of no less than about 0.3 mm. In addition, or as an alternative, the primary tobacco material is ideally shredded into strips having a cut width of less than about 1 mm.
According to a side of the current invention, there is provided a tobacco cut filler comprising a first tobacco materials reduce in accordance with a first reduce specification, whereby the first cut specification units at least 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 getting ready tobacco stem for use as filler for a smoking article includes classifying the green tobacco stem by diameter to offer a plurality of stem grades and rolling every grade separately. Each grade is rolled underneath rolling conditions optimized for that grade including rolling the grade via the nip between rollers with the nip size being adjusted for each grade in order to attain a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted before the rolling.
