In most popular 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 due to this fact be desirable to provide an alternate tobacco minimize filler having improved filling power. At the identical time, it would be fascinating to supply a novel course of for manufacturing tobacco reduce filler, whereby the filling power of the tobacco minimize filler is improved and the manufacturing of tobacco dust is lowered. The current invention relates to the production of tobacco cut filler comprising reconstituted tobacco and to a smoking article shaped from a tobacco rod comprising the reduce filler based on the invention.
These irregular pieces are meant to be related in size to tobacco lamina, such that they are often blended with the tobacco lamina and cut. In specific, the blend is typically minimize into particles having a predetermined reduce width. However, as a end result of the reconstituted tobacco sheet is rather randomly ripped into items, the tobacco fibres are generally not aligned in a uniform path. Tobacco rods had been ready from a tobacco reduce filler utilizing tobacco particles minimize in accordance with the specs of Figures 1 1 and 12. In specific, a primary couple of blends have been used, that contained 85 % by weight of pure tobacco particles and 15 percent by weight of reconstituted tobacco particles minimize in accordance with specifications of Figures 1 1 and 12, respectively.
Figures 1 to 12 reveals minimize strips of a primary tobacco material for incorporation in a minimize filler in accordance with the present invention. The strips have been cut from a sheet of reconstituted tobacco having a thickness from about 0.05 mm to about 1 mm in accordance with a first reduce specification, whereby the primary reduce specification sets a predetermined first reduce width CW1 and a predetermined first reduce length CL1 . In addition, the first reduce specification might additional set a predetermined first sectional reduce width SCW1.
The reduce width of 1 such Y-shaped strip corresponds considerably to the space between the ends of the second and third strip portions as measured along a direction perpendicular to the direction outlined by an axis of the first strip portion. Within the identical Y-shaped strip, the sectional reduce width of every strip portion could as an alternative tobacco pipe be measured alongside a direction substantially perpendicular to the axis of every strip portion. In some cases, such as the place the cut strip of tobacco material is substantially rectangular , the sectional cut width and the strip minimize width are the same.
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 cut in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the reduce width of a person cut strip is taken at the point alongside the size of the strip that yields the most important cross-sectional space. Further, the filling energy Fashion tobacco pipe of the shredded first tobacco material could be maximised by selecting an appropriate first minimize specification. This ends in an improved filling energy of the cut filler as a whole, notably when the primary tobacco material is mixed with no less than another tobacco materials.
Without wishing to be sure to concept, it will be appreciated that in any cutting, rolling or extruding operation, the tobacco fibres usually align in a given direction, which may thus be recognized as the longitudinal course of the tobacco materials. The “cut size” of a reduce strip of tobacco material for incorporation in minimize fillers based on the current invention may subsequently be measured alongside the principle path of fibre alignment, which typically corresponds to the longitudinal path. Thus, the cut Filling cut tobacco length of a person minimize strip could be accurately measured using a conventional measuring system beneath a microscope. In a standard course of, reconstituted tobacco or tobacco stem material or both are usually blended with threshed tobacco lamina to endure a series of treatments, such as conditioning and drying. To this function, a reconstituted tobacco sheet is often ripped into randomly shaped sheet-like pieces having a non-uniform dimension, generally of a quantity of sq. centimetres.
