Alternative strategies for the manufacture of reconstituted tobacco sheets are additionally recognized to the expert individual. Throughout this specification, the expression “reconstituted tobacco sheet” is used to check with a web, ideally with substantially uniform thickness, that may be produced by the rolling or casting of an aqueous slurry or pulp shaped Fashion tobacco pipe from tobacco particles by one of a quantity of methods known within the artwork. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced in the course of the manufacturing course of.
Figures 1 to 12 exhibits reduce strips of a primary tobacco material for incorporation in a cut filler based on the present invention. The strips have been cut from a sheet of reconstituted tobacco having a thickness from about zero.05 mm to about 1 mm in accordance with a primary reduce specification, wherein the first reduce specification sets a predetermined first cut width CW1 and a predetermined first reduce size CL1 . In addition, the first reduce specification might further set a predetermined first sectional cut width SCW1.
The reduce width of one such Y-shaped strip corresponds substantially to the distance between the ends of the second and third strip parts as measured alongside a course perpendicular to the course defined by an axis of the first strip portion. Within the same Y-shaped strip, the sectional reduce width of each strip portion may instead be measured alongside a direction substantially perpendicular to the axis of every strip portion. In some cases, such as where the cut strip of tobacco material is substantially rectangular , the sectional cut width and the strip minimize width are the identical.
The yield of flat rolled stem which can be used directly as filler is elevated, and the typical stem size and thus the common size of cut filler from stem is elevated. A tobacco reduce filler according to any one of the preceding claims having a filling power of a minimum of 3.5 cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. Accordingly, tobacco particles had been ready from the same sheet of reconstituted tobacco according to the cut specification illustrated in Figure 12, wherein the reduce width SCW1 is of 0.9 millimetres, the cut length CL1 is of 4.ninety four millimetres and the global width CW1 is of 12.50 millimetres.
In most well-liked embodiments, the primary tobacco materials is a pre-processed tobacco material. By “pre-processed tobacco material” reference is made all through the specification to a tobacco material produced by man from natural tobacco as opposed to occurring naturally as such. It would subsequently be fascinating to provide another tobacco reduce filler having improved filling energy. At the identical time, it will Filling cut tobacco be fascinating to supply a novel course of for manufacturing tobacco cut filler, whereby the filling power of the tobacco cut filler is improved and the manufacturing of tobacco dust is reduced. The present invention relates to the production of tobacco cut filler comprising reconstituted tobacco and to a smoking article formed from a tobacco rod comprising the minimize filler based on the invention.
Further, the second Y-shaped structure includes a second branching node from which an oblong construction branches off. In the embodiment of Figure 1 1 , the cut strip contains a first Y-shaped construction including 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 third Y-shaped construction branches off.
More preferably, the first tobacco materials is shredded into strips having a cut width of less than about zero.ninety five mm. Even more preferably, the primary tobacco materials is shredded into strips having a reduce width of lower than about 0.9 mm. In most popular embodiments, the first tobacco materials is shredded into strips having a minimize width from about zero.2 mm to about 1 mm. Preferably, the second tobacco material is a pure tobacco leaf material.
