The expressions “last cut width” and “last reduce length” are used herein to describe the reduce width and reduce length of a tobacco material as present in a tobacco minimize filler used in a tobacco product. The technique might further comprise a step of conditioning the primary tobacco materials previous to slicing the first tobacco material. Further, the strategy might comprise a step of controlling the moisture content of the cut filler by adjusting the moisture content of the first tobacco materials.
In most well-liked embodiments, the primary tobacco materials is a pre-processed tobacco material. By “pre-processed tobacco materials” reference is made throughout the specification to a tobacco materials produced by man from pure tobacco as opposed to occurring naturally as such. It would therefore be fascinating to offer an alternative tobacco cut filler having improved filling power. At the same time, it might be fascinating to provide a novel process for manufacturing tobacco minimize filler, whereby the filling power of the tobacco reduce filler is improved and the manufacturing of tobacco dust is lowered. The present invention relates to the production of tobacco minimize filler comprising reconstituted tobacco and to a smoking article formed from a tobacco rod comprising the cut filler based on the invention.
Reconstituted tobacco is fashioned from tobacco material corresponding to tobacco stems, tobacco stalks, leaf scraps and tobacco mud, that are produced during the manufacturing processes of tobacco merchandise. Such tobacco material may, for instance, be ground to a fine powder and then combined with water and typically tobacco pipe with a binder, such as guar gum, to type a slurry. This slurry is then cast onto a supportive floor, similar to a belt conveyor, and dried to kind a sheet (so called ‘cast leaf) that might be faraway from the supportive floor and wound into bobbins.
Without wishing to be sure to concept, it will be appreciated that in any slicing, rolling or extruding operation, the tobacco fibres usually align in a given course, which may thus be identified as the longitudinal course of the tobacco materials. The “cut length” of a reduce strip of tobacco material for incorporation in reduce fillers in accordance with the current invention might due to this fact be measured alongside the primary direction of fibre alignment, which typically corresponds to the longitudinal course. Thus, the minimize length of an individual reduce strip can be precisely measured utilizing a traditional measuring device beneath a microscope. In a conventional process, reconstituted tobacco or tobacco stem material or both are typically blended with threshed tobacco lamina to undergo a series of remedies, such as conditioning and drying. To this function, a reconstituted tobacco sheet is typically ripped into randomly formed sheet-like pieces having a non-uniform measurement, usually of a quantity of square centimetres.
Figures 1 to 12 shows cut strips of a first tobacco material for incorporation in a reduce filler in accordance with 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 primary reduce specification units a predetermined first cut width CW1 and a predetermined first reduce length CL1 . In addition, the primary minimize specification may 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 parts as measured along a course perpendicular to the course outlined by an axis of the primary strip portion. Within the identical Y-shaped strip, the sectional minimize width of each strip portion might instead be measured alongside a direction substantially perpendicular to the axis of every strip portion. In some cases, similar to the place the cut strip of tobacco material is substantially rectangular , the sectional minimize width and the strip minimize width are the same.
