A tobacco cut filler according to any one of the preceding claims, whereby the first tobacco material is a reconstituted tobacco sheet. Preferably, the cut filler has a filling power of no much less than about 3.5 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. More preferably, the cut filler has a filling energy of no less than about 4 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. In addition, or in its place, the minimize filler preferably has a filling energy of less than about eight cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles.
A tobacco cut filler according to claim 1 or 2, wherein the first tobacco materials is a pre- processed tobacco materials. In a third experiment, the minimize specification no. 10 was barely modified with a view to bettering the resistance of the particles to the stresses involved by the cigarette-making process. In explicit, there was concern that in the course of the cigarette-making course of the tobacco particle can be exposed to high tensions and frictions which might cause particles ready in accordance with the cut specification no. 10 to interrupt. This may have lowered the profit coming from the V-shape and shown by the CCV measurements described above. Figure 13 depicts a schematic view of an apparatus for forming a tobacco cut filler in accordance with the present invention. Figures depict a quantity of examples of notably shapes into which tobacco materials for forming a cut filler in accordance with the current invention could also be cut.
In addition, a second couple of blends was used, that contained 70 % by weight of natural tobacco particles and 30 % by weight of reconstituted tobacco particles cut in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the reduce width of an individual reduce strip is taken at the point alongside the length of the strip that yields the largest cross-sectional area. Further, the filling power of the shredded first tobacco material may be maximised by deciding on an appropriate first reduce specification. This ends in an improved filling power of the reduce filler as a whole, notably when the primary tobacco materials is blended with a minimum of one other tobacco materials.
A tobacco reduce filler based on any one of the preceding claims, wherein the primary tobacco material is shredded into strips having a reduce length from about 5 mm to about 60 mm. A tobacco cut filler in accordance with any considered one of claims 2 to four, whereby the second tobacco materials is a pure tobacco leaf materials. An angle of ninety levels was thought of to be undesirable, in that it will lead basically to a shape fairly just like the form of Figure 6, and so an angle of 60 degrees was chosen for the “V” parts. Further, the method ideally contains the step of mixing the cut first tobacco materials and the minimize second tobacco materials.
More preferably, the first tobacco materials is shredded into strips having a reduce width of less than about zero.ninety five mm. Even more preferably, the first tobacco materials is shredded into strips having a cut width of lower than about zero.9 mm. In most popular embodiments, the primary tobacco materials is shredded into strips having a cut width from about zero.2 mm to about 1 mm. Preferably, the second tobacco material is a natural tobacco leaf materials.
Without wishing to be bound to theory, it is going to be appreciated that in any cutting, rolling or extruding operation, the tobacco fibres typically align in a given direction, which can thus be identified because the longitudinal path of the tobacco material. The “cut size” of a reduce strip of tobacco materials for incorporation in minimize fillers according to the current invention may therefore be measured alongside the primary path of fibre alignment, which generally corresponds to the longitudinal path. Thus, the cut tobacco pipe size of a person minimize strip could be precisely measured utilizing a standard measuring gadget beneath a microscope. In a conventional course of, reconstituted tobacco or tobacco stem materials or each are usually blended with threshed tobacco lamina to endure a collection of therapies, such as conditioning and drying. To this purpose, a reconstituted tobacco sheet is typically ripped into randomly formed sheet-like items having a non-uniform measurement, generally of a number of sq. centimetres.
In most popular embodiments, the primary tobacco material is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even extra preferably, the primary tobacco material is shredded into strips from a sheet material having a thickness from about 0.1 mm to about 0.three mm, most preferably from a sheet materials having a thickness of about 0.2 mm. A tobacco minimize filler based on any considered one of claims 1 to 9, whereby the first tobacco material is shredded into strips each comprising at least a first strip construction comprising a branching node from which an extra strip construction 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 construction. Each V construction contains two substantially straight components forming an angle.
The term “reduce specification” is used all through the specification to discuss with the assorted geometric parameters characterising the strips obtained by subjecting a tobacco material to a slicing operation. Thus, in accordance to a given “cut specification”, a tobacco material shall be cut or shredded into strips having a predetermined minimize width, cut length, cut form and so forth. Further, it might be desirable to supply one such improved course of that allows for a greater management of the form, size and properties of the reconstituted tobacco matter forming part of the minimize filler. At the identical time, it would be desirable to provide one such course of that does not require any major modification of the traditional equipment and amenities used in the primary treatment of tobacco.
