Figures 1 to 12 shows cut strips of a first tobacco materials for incorporation in a reduce filler in accordance with the current invention. The strips have been reduce from a sheet of reconstituted tobacco having a thickness from about zero.05 mm to about 1 mm in accordance with a first minimize specification, whereby the first cut specification units a predetermined first cut width CW1 and a predetermined first reduce length CL1 . In addition, the primary reduce specification might further set a predetermined first sectional cut width SCW1.
Experiments had been carried out so as to assess the impression of different shapes and minimize specs to key parameters of tobacco reduce filler particles, such as the filling energy. In more element, Figure 1 reveals a zigzag-shaped strip and Figure 2 exhibits a wave-shaped strip. Where the reduce strip is zigzag-shaped or wave- shaped, it is potential to measure a wave length of the cut strip, which substantially corresponds to the strip minimize length divided by the number of repetitions of the zigzag or wave. For occasion , in the cut strip of Figure 1 the zigzag is repeated 10 times. Preferably, a wave size of the sinusoidal shape is from about 1 mm to about 15 mm, extra ideally from about 2 mm to about 12 mm, even more ideally from 4 mm to 10 mm. Preferably, the tobacco minimize filler further includes a second tobacco material minimize in accordance with a second reduce specification differing from the primary cut specification for at least one of cut length and cut width.
A tobacco cut filler in accordance with declare 1 or 2, wherein the primary tobacco materials is a pre- processed tobacco materials. In a third experiment, the minimize specification no. 10 was slightly modified with a view to bettering the resistance of the particles to the stresses concerned by the cigarette-making process. In specific, there was concern that during the cigarette-making process the tobacco particle could be exposed to high tensions and frictions which might trigger particles ready in accordance with the reduce 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 thirteen depicts a schematic view of an apparatus for forming a tobacco reduce filler in accordance with the current invention. Figures depict a number of examples of significantly shapes into which tobacco materials for forming a cut filler in accordance with the present invention may be reduce.
Alternative strategies for the manufacture of reconstituted tobacco sheets are also recognized to the skilled 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 tobacco pipe from tobacco particles by one of several methods recognized in the artwork. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced in the course of the manufacturing process.
By distinction, in a multimodal distribution, the likelihood mass operate has multiple maxima, which implies that among the many cut strips of the first tobacco materials there are multiple values of reduce size that happen most frequently. In the context of the present specification, a distribution having multiple native maxima is regarded as multimodal. It will be appreciated that the completely different modes in a multimodal distribution can also have totally different frequencies, such that, among the cut strips of the first tobacco material, one modal value of minimize size will happen extra frequently than one other modal worth.
In addition, a second couple of blends was used, that contained 70 p.c by weight of natural tobacco particles and 30 % by weight of reconstituted tobacco particles reduce in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the minimize width of a person reduce strip is taken on the point alongside the length of the strip that yields the largest cross-sectional space. Further, the filling power of the shredded first tobacco material can be maximised by selecting a suitable first minimize specification. This leads to an improved filling energy of the minimize filler as an entire, notably when the primary tobacco material is mixed with at least one other tobacco materials.
