Figures 1 to 12 shows cut strips of a first tobacco material for incorporation in a cut filler in accordance with the current 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 cut specification units a predetermined first reduce width CW1 and a predetermined first minimize size CL1 . In addition, the primary cut specification may additional set a predetermined first sectional cut width SCW1.
In most well-liked embodiments, the primary tobacco material is a pre-processed tobacco material. By “pre-processed tobacco materials” reference is made all through the specification to a tobacco material produced by man from natural tobacco versus occurring naturally as such. It would subsequently be fascinating to supply an alternate tobacco minimize filler having improved filling power. At the identical time, it would tobacco pipe be fascinating to offer a novel course of for manufacturing tobacco reduce filler, whereby the filling power of the tobacco minimize filler is improved and the production of tobacco mud is reduced. The current invention relates to the production of tobacco minimize filler comprising reconstituted tobacco and to a smoking article shaped from a tobacco rod comprising the reduce filler based on the invention.
The values of filling energy are expressed by means of corrected cylinder quantity which is the cylinder quantity of the tobacco material at a reference moisture stage of 12.5 p.c oven volatiles. The cylinder volume could also be decided using a Borgwaldt densimeter DD60 or DD60A type Fashion tobacco pipe fitted with a measuring head for reduce tobacco and a tobacco cylinder container. The time period “sinusoidal” is used to describe a minimize strip of tobacco materials shaped substantially like a portion of a sine wave.
Experiments were carried out to find a way to assess the impression of different shapes and reduce specs to key parameters of tobacco minimize filler particles, such as the filling power. In extra element, Figure 1 reveals a zigzag-shaped strip and Figure 2 shows a wave-shaped strip. Where the reduce strip is zigzag-shaped or wave- shaped, it’s attainable to measure a wave length of the cut strip, which substantially corresponds to the strip minimize length divided by the number of repetitions of the zigzag or wave. For instance Filling cut tobacco, within the cut strip of Figure 1 the zigzag is repeated 10 times. Preferably, a wave length of the sinusoidal form is from about 1 mm to about 15 mm, extra preferably from about 2 mm to about 12 mm, much more preferably from four mm to 10 mm. Preferably, the tobacco reduce filler additional contains a second tobacco material minimize in accordance with a second cut specification differing from the first cut specification for at least certainly one of reduce size and cut width.
More ideally, the primary tobacco materials is shredded into strips having a reduce width of lower than about 0.95 mm. Even extra ideally, the primary tobacco material is shredded into strips having a cut width of lower than about 0.9 mm. In preferred embodiments, the primary 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 pure tobacco leaf materials.
Without wishing to be certain to principle, it will be appreciated that in any chopping, rolling or extruding operation, the tobacco fibres usually align in a given course, which can thus be identified as the longitudinal course of the tobacco material. The “reduce size” of a reduce strip of tobacco materials for incorporation in cut fillers in accordance with the present invention may therefore be measured alongside the main path of fibre alignment, which usually corresponds to the longitudinal path. Thus, the cut length of an individual minimize strip can be accurately measured using a traditional measuring device underneath a microscope. In a conventional process, reconstituted tobacco or tobacco stem material or each are typically blended with threshed tobacco lamina to undergo a series of treatments, corresponding to conditioning and drying. To this function, a reconstituted tobacco sheet is often ripped into randomly shaped sheet-like items having a non-uniform size, typically of a quantity of sq. centimetres.
