Further, the second Y-shaped construction includes a second branching node from which a rectangular structure branches off. In the embodiment of Figure 1 1 , the cut strip comprises a primary Y-shaped structure including a primary branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped construction comprises a second branching node from which a 3rd Y-shaped construction branches off.
Suitable natural tobacco leaf materials embrace tobacco lamina, tobacco stem material and tobacco stalk material. The pure tobacco leaf material used because the second tobacco materials might include any type 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 minimize filler based on the present invention comprises a first tobacco material reduce in accordance with a primary minimize specification, wherein the primary minimize specification units at least predetermined first cut width and first reduce size. The time period “filling power” is used to describe the amount of area taken up by a given weight or mass of a tobacco materials. The larger the filling power of a tobacco material, the decrease the burden of the material required to fill a tobacco rod of standard dimensions.
This document specifies a method for dedication of filling energy for preparation of fine-cut tobacco smoking articles. Its leaves are 20 – 50 cm lengthy and vary in color from mild brown to very dark brown. When the lowest leaves are harvested, the entire plant can both be reduce down and dried or the plant could be harvested leaf-by-leaf. A methodology based on any considered one of claims 15 to 18, further comprising conditioning the first tobacco material prior to cutting the first tobacco materials . A technique according to declare 18, comprising controlling the moisture content material of the reduce filler by adjusting the moisture content material of the primary tobacco materials. A tobacco cut filler based on claim 1 , further comprising a second tobacco materials minimize in accordance with a second cut specification differing from the primary minimize specification for no much less than considered one of cut length and minimize width.
In statistics, a unimodal distribution is a distribution which has a single mode. In a discrete likelihood distribution – as is the case with the distribution of minimize size or minimize width values in a inhabitants of particles of the primary tobacco material – the mode is a worth at which the probability mass operate takes its maximum value. In different words, in the present specification, the mode of a unimodal distribution will identify a most probably worth of reduce width or reduce length in a population of particles of the tobacco material. In practice, if the amount of particles having a sure cut length or reduce width is plotted in opposition to the increasing minimize length or reduce width, the chart of the quantity of particles will usually have a single maximum.
According to a facet of the present invention, there is supplied a tobacco minimize filler comprising a first tobacco materials cut in accordance with a primary minimize specification, whereby the first cut specification sets at least predetermined first minimize width and first cut 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 contains classifying the green tobacco stem by diameter to supply a plurality of stem grades and rolling every grade separately. Each grade is rolled beneath rolling conditions optimized for that grade together with rolling the grade through the nip between rollers with the nip measurement being adjusted for each grade in order to attain a uniform rolled stem thickness and the oven volatiles content material of the stem being adjusted earlier than the rolling.
In flip, the third Y-shaped construction includes a 3rd branching node from which a rectangular construction branches off. In the embodiments of each Figures 9 and 1 1 the sectional reduce width inside all of the buildings forming the reduce strips is considerably fixed. By method of instance, in a Y-shaped strip it’s attainable to identify a primary strip portion extending along a first direction and a second and third strip portions extending from the primary strip parts along diverging instructions, so that they type an angle.
Even extra preferably, the first tobacco materials is shredded into strips from a sheet material having a thickness of at least about 0.2 mm. In addition, or as an alternative, the first tobacco materials is ideally shredded into strips from a sheet material having a thickness of lower than about 1 mm. More ideally, the first tobacco material is shredded into strips from a sheet materials having a thickness of lower than about 0.95 mm. Even extra ideally, the first tobacco materials is shredded into strips from a sheet material having a thickness of lower than about zero.85 mm.
Even extra ideally, first tobacco materials is shredded into strips having a minimize length of at least about 15 mm. In addition, or as an alternative, the first tobacco materials is ideally shredded into strips having a cut size of less than about 60 mm. More ideally, the primary tobacco material is shredded into strips having a minimize size of less than about 50 mm. Even more ideally, the first tobacco material is shredded into strips having a minimize size of less than about forty 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 cut width” is used in the current specification to explain the side- to-side width of one such portion of a reduce strip of tobacco materials.
In some embodiment, the reduce width distribution among the many cut strips of the first tobacco material is preferably unimodal. In different embodiments, the reduce width distribution among the cut strips of the first tobacco material may be multimodal, including specifically bimodal and trimodal. If a distribution has two or extra Filling cut tobacco modes, it’s typically known as multimodal. Particular examples are bimodal and trimodal distributions, which have two and three modes, respectively. Preferably, the first tobacco material is shredded into strips having a minimize width of a minimal of about 0.2 mm.
