In addition, a second couple of blends was used, that contained 70 p.c by weight of pure tobacco particles and 30 percent by weight of reconstituted tobacco particles cut in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the minimize width of a person minimize strip is taken at the point along the size of the strip that yields the biggest cross-sectional space. Further, the filling energy of the shredded first tobacco material could be maximised by selecting an acceptable first minimize specification. This results in an improved filling power of the reduce filler as a whole, particularly when the primary tobacco materials is mixed with at least another tobacco materials.
Alternative strategies for the manufacture of reconstituted tobacco sheets are also known to the expert particular person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to refer to an online, ideally with substantially uniform thickness, which might be produced by the rolling or casting of an aqueous slurry or pulp fashioned from tobacco particles by certainly one of several methods recognized in the art. Suitable by-products embody tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced in the course of the manufacturing process.
Even more preferably, the first tobacco material is shredded into strips from a sheet materials having a thickness of at least about zero.2 mm. In addition, or instead, the primary tobacco materials is ideally shredded into strips from a sheet material having a thickness of less than about 1 mm. More preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of lower than about 0.95 mm. Even more preferably, the primary tobacco materials is shredded into strips from a sheet material having a thickness of less than about zero.eighty five mm.
Without wishing to be bound to concept, will probably be appreciated that during any slicing, rolling or extruding operation, the tobacco fibres typically align in a given path, which can thus be identified as the longitudinal direction of the tobacco materials. The “cut length” of a cut strip of tobacco materials for incorporation in cut fillers in accordance with the current invention may due to this fact be measured alongside the main course of fibre alignment, which typically corresponds to the longitudinal course. Thus, the minimize size of an individual reduce strip could be precisely measured utilizing a conventional measuring system beneath a microscope. In a traditional process, reconstituted tobacco or tobacco stem materials or both are typically blended with threshed tobacco lamina to undergo a sequence of treatments, such as conditioning and drying. To this purpose, a reconstituted tobacco sheet is usually ripped into randomly shaped sheet-like items having a non-uniform dimension, usually of several sq. centimetres.
The minimize width of one such Y-shaped strip corresponds substantially to the space between the ends of the second and third strip portions as measured along a course perpendicular to the path outlined by an axis of the first strip portion. Within the identical Y-shaped strip, the sectional cut width of every strip portion could instead Fashion tobacco pipe be measured along a course considerably perpendicular to the axis of each strip portion. In some instances, such as the place the minimize strip of tobacco materials is substantially rectangular , the sectional reduce width and the strip minimize width are the same.
In preferred embodiments, the first tobacco materials is shredded into strips from a sheet material having a thickness from about zero.05 mm to about 1 mm. Even more preferably, the primary tobacco materials is shredded into strips from a sheet material having a thickness from about zero.1 mm to about zero.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, whereby the first Filling cut tobacco tobacco materials is shredded into strips each comprising a minimum of a primary strip structure comprising a branching node from which an additional strip structure branches off, forming an angle with the first strip structure. Figures 10 and 12 present two examples of minimize strips together with a number of V-shaped construction. Each V structure includes two considerably straight elements forming an angle.
By contrast, in a multimodal distribution, the probability mass function has multiple maxima, which signifies that among the many cut strips of the first tobacco materials there are a quantity of values of cut length that happen most often. In the context of the current specification, a distribution having a number of local maxima is considered tobacco pipe multimodal. It shall be appreciated that the different modes in a multimodal distribution may also have completely different frequencies, such that, among the reduce strips of the primary tobacco materials, one modal value of reduce length will happen extra incessantly than one other modal value.
A tobacco minimize filler based on claim 1 or 2, whereby the primary tobacco material is a pre- processed tobacco material. In a third experiment, the minimize specification no. 10 was barely modified with a view to enhancing the resistance of the particles to the stresses concerned by the cigarette-making process. In particular, there was concern that during the cigarette-making course of the tobacco particle would be exposed to high tensions and frictions which might trigger particles prepared in accordance with the cut specification no. 10 to break. This could have decreased the profit coming from the V-shape and shown by the CCV measurements described above. Figure thirteen depicts a schematic view of an apparatus for forming a tobacco minimize filler in accordance with the present invention. Figures depict several examples of particularly shapes into which tobacco materials for forming a reduce filler in accordance with the present invention may be minimize.
