Should one such particle break at a location in the central V-shaped portion, the two ensuing components of the particles would nonetheless be successfully V-shaped. The highest CCV values had been obtained for cut specification no. three, which substantially corresponds to particles having a Y-shape. However, it was discovered that when particles were produced from the identical sheet of reconstituted tobacco in accordance with cut specification no. 3 are produced, a big fraction of the tobacco materials went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed within the following Table 3 have been measured. Tobacco reduce fillers based on the current invention could also be prepared by a technique comprising offering a first tobacco material and chopping the first tobacco material in accordance with a primary cut specification setting at least predetermined first minimize width and first reduce length. Tobacco reduce filler in accordance with the present invention may be integrated into a variety of smoking articles.
The shredding system is configured to cut the reconstituted tobacco in accordance to a first minimize specification, whereby each minimize width and cut size are predetermined. The cut strips are dropped onto a conveyor belt 38 arranged beneath the shredding system 36 and defining a collection surface upon which the reduce strips fall out of the shredding gadget. Additional means T could additionally be offered for tensioning the web of reconstituted tobacco as it is unwound off the bobbin. Further, the equipment 30 may comprise sensors 40 for detecting the moisture content of the online of reconstituted tobacco upstream of the shredding device 36. In addition, the apparatus 30 may comprise mass flow controllers 42, forty four tailored to adjust the pace at which the web of reconstituted tobacco is fed to the shredding system 36 and the speed of the conveyor belt 38.
Conventionally, minimize filler tobacco products for smoking articles are formed predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf throughout a threshing course of. Much of the stem portion that is still after the lamina has been removed and separated just isn’t used. However, it isn’t unusual to add some tobacco stems again into the minimize filler along with the lamina.
More preferably, the first tobacco material is shredded into strips having a reduce width of lower than about zero.95 mm. Even extra preferably, the first tobacco materials is shredded into strips having a reduce width of lower than about zero.9 mm. In most well-liked embodiments, the first tobacco materials is shredded into strips having a reduce width from about 0.2 mm to about 1 mm. Preferably, the second tobacco materials is a pure tobacco leaf materials.
Even more preferably, the first tobacco material is shredded into strips from a sheet materials having a thickness of a minimum of about zero.2 mm. In addition, or as an alternative, the primary tobacco material is ideally shredded into strips from a sheet material having a thickness of less than about 1 mm. More ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness of less than about zero.ninety five mm. Even extra preferably, the first tobacco material is shredded into strips from a sheet material having a thickness of less than about 0.eighty five mm.
In addition, the formation of tobacco dust is decreased in contrast with conventional manufacturing methods. Accordingly, the necessity to gather and re-process tobacco mud is considerably lowered and the general effectivity of the manufacturing course of is thus advantageously increased. A tobacco reduce filler in accordance with any one of many previous claims, wherein the primary tobacco materials is shredded into strips having a sinusoidal shape, wherein a wave length of the sinusoidal shape is from about 1 mm to about 15 mm. A tobacco reduce filler based on any one of the previous claims, whereby the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about 0.05 mm to about 1 mm. Table 2 beneath lists the values of CCV measured at a reference moisture value of 12.5 p.c oven volatiles for each sample.
A tobacco reduce filler according to declare 1 or 2, whereby the primary tobacco materials is a pre- processed tobacco material. 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 concerned by the cigarette-making process. In explicit, there was concern that during the cigarette-making process the tobacco particle could be uncovered to excessive tensions and frictions which might trigger particles prepared in accordance with the cut specification no. 10 to break. This may have decreased the profit coming from the V-shape and shown by the CCV measurements described above. Figure 13 depicts a schematic view of an equipment for forming a tobacco minimize filler in accordance with the current invention. Figures depict several examples of particularly shapes into which tobacco materials for forming a cut filler in accordance with the current invention may be minimize.
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 comprises a first Y-shaped structure including Filling cut tobacco a primary branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped construction comprises a second branching node from which a 3rd Y-shaped construction branches off.
