The term “minimize specification” is used throughout the specification to check with the various geometric parameters characterising the strips obtained by subjecting a tobacco material to a chopping operation. Thus, in accordance to a given “cut specification”, a tobacco material shall be reduce or shredded into strips having a predetermined cut width, cut size, minimize shape and so forth. Further, it would be fascinating to supply one such improved course of that enables for a greater control of the form, size and properties of the reconstituted tobacco matter forming a part of the cut filler. At the same time, it might be desirable to provide one such process that doesn’t require any main modification of the traditional apparatus and facilities used in the primary treatment of tobacco.
More ideally, the first tobacco materials is shredded into strips having a minimize width of a minimal of about 0.25 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 instead, the primary tobacco materials is preferably shredded into strips having a minimize width of less than about 1 mm.
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 may embody any kind of tobacco leaf, together with for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco reduce filler according to the present invention comprises a primary tobacco materials minimize in accordance with a primary minimize specification, whereby the first cut specification units no less than predetermined first minimize width and first cut length. The term “filling power” is used to describe the quantity of house taken up by a given weight or mass of a tobacco material. The greater the filling power of a tobacco material, the lower the burden of the fabric required to fill a tobacco rod of normal dimensions.
Further, the second Y-shaped structure comprises a second branching node from which an oblong construction branches off. In the embodiment of Figure 1 1 , the reduce strip includes a primary Y-shaped structure together Fashion tobacco pipe with a primary branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped structure comprises a second branching node from which a third Y-shaped structure branches off.
Should one such particle break at a location in the central V-shaped portion, the 2 resulting components of the particles would nonetheless be effectively V-shaped. The highest CCV values had been obtained for minimize 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 reduce 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 in the following Table 3 were measured. Tobacco cut fillers according to the current invention may be ready by a method comprising providing a primary tobacco material and slicing the first tobacco material in accordance with a first minimize specification setting a minimal of predetermined first reduce width and first cut size. Tobacco reduce filler in accordance with the current invention could additionally be included into a variety of smoking articles.
For example, a bimodal distribution might correspond successfully to two teams of reduce strips having completely different average cut lengths , one group being bigger than the opposite. Preferably, the first tobacco material is shredded into strips from a sheet materials having a thickness of a minimal of about zero.05 mm. More preferably, the primary tobacco material is shredded into strips from a sheet material having a thickness of no less than about zero.1 mm.
The reduce width of 1 such Y-shaped strip corresponds substantially to the distance between the ends of the second and third strip portions as measured alongside a course perpendicular to the course defined by an axis of the primary strip portion. Within the identical Y-shaped strip, the sectional minimize width of every strip portion may as a substitute be measured alongside a direction substantially perpendicular to the axis of every strip portion. In some instances, corresponding to where the cut strip of tobacco materials is substantially rectangular , the sectional minimize width and the strip minimize width are the identical.
In most popular embodiments, the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Even more ideally, the first tobacco material is shredded into strips from a sheet materials 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 certainly one of claims 1 to 9, whereby the primary tobacco materials is shredded into strips every comprising at least a primary strip construction comprising a branching node from which an extra strip structure branches off, forming an angle with the primary strip structure. Figures 10 and 12 show two examples of cut strips together with one or more V-shaped structure. Each V structure includes two considerably straight elements forming an angle.
Even extra preferably, the first tobacco material is shredded into strips from a sheet materials having a thickness of no much less than about zero.2 mm. In addition, or in its place, the primary tobacco material is ideally shredded into strips from a sheet materials having a thickness of less than about 1 mm. More ideally Filling cut tobacco, the first tobacco material is shredded into strips from a sheet material having a thickness of less than about 0.95 mm. Even more ideally, the first tobacco material is shredded into strips from a sheet material having a thickness of lower than about 0.85 mm.
