Conventionally, reduce filler tobacco merchandise for smoking articles are shaped predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf throughout a threshing process. Much of the stem portion that is still after the lamina has been removed and separated is not used. However, it is not unusual to add some tobacco stems again into the cut filler along with the lamina.
The shredding device is configured to chop the reconstituted tobacco in accordance to a first reduce specification, whereby both minimize width and minimize length are predetermined. The cut strips are dropped onto a conveyor belt 38 organized beneath the shredding gadget 36 and defining a group floor upon which the cut strips fall out of the shredding device. Additional means T may be provided for tensioning the web of reconstituted tobacco as it tobacco pipe is unwound off the bobbin. Further, the equipment 30 might comprise sensors forty for detecting the moisture content of the online of reconstituted tobacco upstream of the shredding system 36. In addition, the equipment 30 could comprise mass flow controllers 42, 44 adapted to regulate the speed at which the net of reconstituted tobacco is fed to the shredding gadget 36 and the pace of the conveyor belt 38.
For example, a bimodal distribution may correspond effectively to 2 groups of reduce strips having completely different common reduce lengths , one group being larger than the other. Preferably, the first tobacco materials is shredded into strips from a sheet materials having a thickness of a minimum of about 0.05 mm. More ideally, the first tobacco material is shredded into strips from a sheet material having a thickness of no less than about zero.1 mm.
Because of the reduced tobacco fibre size within the reconstituted tobacco material, publicity to the same therapies as tobacco lamina could degrade, to some extent, the reconstituted tobacco. By way of example, during drying, the moisture content material of reconstituted tobacco is greatly decreased, leading to shrinkage of the tobacco particles forming the reconstituted tobacco sheet. Additionally, the chopping techniques typically employed to transform the tobacco materials blend into filler may result in some lamination and compression of the reconstituted tobacco material. All this causes a reduction within the filling energy of the treated reconstituted tobacco and, accordingly, of the tobacco cut filler as a whole. A mode of a discrete likelihood distribution, as is the case with the cut size distribution among the many cut strips of the first tobacco materials is a price at which the chance mass operate takes a maximum worth. Thus, in a unimodal distribution, the likelihood mass operate solely has one maximum worth, and that corresponds to the more than likely worth of reduce length .
Further, the second Y-shaped construction contains a second branching node from which an oblong construction branches off. In the embodiment of Figure 1 1 , the minimize strip contains a first Y-shaped construction together Fashion tobacco pipe with a primary branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped structure includes a second branching node from which a 3rd Y-shaped construction branches off.
More ideally, the primary tobacco materials is shredded into strips having a cut width of lower than about zero.ninety five mm. Even extra ideally, the first tobacco materials is shredded into strips having a cut width of lower than about zero.9 mm. In most well-liked embodiments, the first tobacco material is shredded into strips having a cut width from about 0.2 mm to about 1 mm. Preferably, the second tobacco material is a natural tobacco leaf materials.
