Suitable natural tobacco leaf supplies include tobacco lamina, tobacco stem materials and tobacco stalk material. The natural tobacco leaf material used because the second tobacco materials may embrace any sort of tobacco leaf, together with for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco reduce filler based on the current invention includes a primary tobacco material minimize in accordance with a primary Fashion tobacco pipe cut specification, wherein the first reduce specification sets a minimum of predetermined first minimize width and first minimize size. The term “filling energy” is used to describe the quantity of house taken up by a given weight or mass of a tobacco materials. The higher the filling power of a tobacco materials, the decrease the burden of the material required to fill a tobacco rod of normal dimensions.
Alternative methods for the manufacture of reconstituted tobacco sheets are also identified to the skilled person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to discuss with an online, preferably with substantially uniform thickness, which could be produced by the rolling or casting of an aqueous slurry or pulp formed from tobacco particles by considered one of several strategies known in the artwork. Suitable by-products embody tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced during the manufacturing course of.
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 materials is shredded into strips from a sheet materials having a thickness from about 0.1 mm to about 0.three mm, most preferably from a sheet material having a thickness of about zero.2 mm. A tobacco reduce filler in accordance with any certainly one of claims 1 to 9, wherein the primary tobacco materials is shredded into strips every comprising at least a primary strip structure comprising a branching node from which an additional strip construction branches off, forming an angle with the first strip construction. Figures 10 and 12 show two examples of minimize strips together with a quantity of V-shaped construction. Each V structure includes two considerably straight elements forming an angle.
The yield of flat rolled stem which can be used immediately as filler is elevated, and the common stem size and thus the average size of reduce filler from stem is increased. A tobacco cut filler based on any one of the previous claims having a filling energy of no much less than three.5 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles. Accordingly, tobacco particles had been prepared from the same sheet of reconstituted tobacco in accordance with the reduce specification illustrated in Figure 12, whereby the minimize width SCW1 is of 0.9 millimetres, the minimize size CL1 is of four.94 millimetres and the worldwide width CW1 is of 12.50 millimetres.
More ideally, the first tobacco materials is shredded into strips having a cut width of a minimal of about zero.25 mm. Even more ideally, the primary tobacco material is shredded into strips having a cut width of a minimal of about 0.three mm. In addition, or instead, the primary tobacco materials is preferably shredded into strips having a minimize width of lower than about 1 mm.
Further, the second Y-shaped structure contains a second branching node from which an oblong construction branches off. In the embodiment of Figure 1 1 , the cut strip contains a primary Y-shaped structure together with a first branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped structure comprises a second branching node from which a third Y-shaped construction branches off.
A tobacco reduce filler according to declare 1 or 2, whereby the primary tobacco materials is a pre- processed tobacco materials. In a third experiment, the reduce specification no. 10 was slightly modified with a view to improving the resistance of the particles to the stresses involved by the cigarette-making course of. In specific, there was concern that during the cigarette-making process the tobacco particle would be exposed to high tensions and frictions which might trigger particles prepared in accordance with the reduce specification no. 10 to interrupt. This may have decreased the benefit coming from the V-shape and proven by the CCV measurements described above. Figure 13 depicts a schematic view of an equipment for forming a tobacco cut filler in accordance with the present invention. Figures depict a number of examples of particularly shapes into which tobacco materials for forming a minimize filler in accordance with the present invention may be reduce.
The cut width of 1 such Y-shaped strip corresponds substantially to the distance between the ends of the second and third strip parts as measured along a course perpendicular to the course outlined by an axis of the first strip portion. Within the same Y-shaped strip, the sectional reduce width of every strip portion may instead tobacco pipe be measured alongside a direction substantially perpendicular to the axis of each strip portion. In some instances, similar to the place the minimize strip of tobacco materials is substantially rectangular , the sectional minimize width and the strip minimize width are the identical.
