In addition, a second couple of blends was used, that contained 70 % by weight of pure tobacco particles and 30 % by weight of reconstituted tobacco particles cut in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the minimize width of an individual minimize strip is taken on the point along the length of the strip that yields the largest cross-sectional area. Further, the filling power tobacco pipe of the shredded first tobacco materials could be maximised by deciding on a suitable first minimize specification. This leads to an improved filling power of the reduce filler as an entire, significantly when the primary tobacco materials is mixed with at least one other tobacco material.
The yield of flat rolled stem which may be used instantly as filler is elevated, and the common stem length and thus the average length of reduce filler from stem is increased. A tobacco reduce filler according to any one of many previous claims having a filling energy of a minimum of three.5 cubic centimetres per gram at a reference moisture worth Filling cut tobacco of 12.5 percent oven volatiles. Accordingly, tobacco particles have been prepared from the same sheet of reconstituted tobacco according to the minimize specification illustrated in Figure 12, whereby the cut width SCW1 is of zero.9 millimetres, the cut size CL1 is of 4.94 millimetres and the global width CW1 is of 12.50 millimetres.
The minimize width of one such Y-shaped strip corresponds substantially to the space between the ends of the second and third strip portions as measured alongside a direction perpendicular to the course outlined by an axis of the first strip portion. Within the same Y-shaped strip, the sectional minimize width of each strip portion may instead be measured alongside a path substantially perpendicular to the axis of every strip portion. In some instances, corresponding to where the reduce strip of tobacco material is substantially rectangular , the sectional minimize width and the strip reduce width are the same.
Alternative strategies for the manufacture of reconstituted tobacco sheets are also recognized to the skilled individual. Throughout this specification, the expression “reconstituted tobacco sheet” is used to discuss with a web, preferably with considerably uniform thickness, that might be produced by the rolling or casting of an aqueous slurry or pulp fashioned from tobacco particles by considered one of a quantity of methods known within the artwork. Suitable by-products embody tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced through the manufacturing course of.
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 cut strip includes 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 contains a second branching node from which a third Y-shaped construction branches off.
