Figures 1 to 12 reveals cut strips of a first tobacco materials for incorporation in a minimize filler in accordance with the current invention. The strips have been reduce from a sheet of reconstituted tobacco having a thickness from about zero.05 mm to about 1 mm in accordance with a primary minimize specification, wherein the primary cut specification units a predetermined first minimize width CW1 and a predetermined first cut length CL1 . In addition, the primary minimize specification could additional set a predetermined first sectional reduce width SCW1.
In most well-liked embodiments, the first tobacco material is a pre-processed tobacco material. By “pre-processed tobacco material” reference is made throughout the specification to a tobacco materials produced by man from natural tobacco versus occurring naturally as such. It would therefore be fascinating to supply an alternative tobacco reduce filler having improved filling power. At the identical time, it will tobacco pipe be fascinating to provide a novel process for manufacturing tobacco reduce filler, whereby the filling power of the tobacco minimize filler is improved and the manufacturing of tobacco mud is reduced. The present invention pertains to the manufacturing of tobacco minimize filler comprising reconstituted tobacco and to a smoking article shaped from a tobacco rod comprising the reduce filler according to the invention.
In preferred embodiments, the first tobacco material is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Even extra preferably, the first tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.1 mm to about zero.three mm, most ideally from a sheet materials having a thickness of about 0.2 mm. A tobacco reduce filler in accordance with any certainly one of claims 1 to 9, whereby the primary tobacco materials is shredded into strips every comprising a minimum of a primary strip construction comprising a branching node from which an additional strip construction branches off, forming an angle with the primary strip construction. Figures 10 and 12 present two examples of cut strips together with a number of V-shaped structure. Each V structure contains two substantially straight components forming an angle.
The minimize width of one such Y-shaped strip corresponds considerably to the distance between the ends of the second and third strip portions as measured along a path perpendicular to the path defined by an axis of the primary strip portion. Within the identical Y-shaped strip, the sectional cut width of each strip portion may as an alternative be measured along a path considerably perpendicular to the axis of each strip portion. In some circumstances, similar to where the minimize strip of tobacco materials is substantially rectangular , the sectional minimize width and the strip minimize width are the identical.
By contrast, in a multimodal distribution, the chance mass function has a quantity of maxima, which means that among the minimize strips of the primary tobacco material there are a number of values of reduce size that occur most frequently. In the context of the present specification, a distribution having a quantity of native maxima is thought to be multimodal. It will be appreciated that the different modes in a multimodal distribution can also have different frequencies, such that, among the many reduce strips of the first tobacco materials, one modal value of cut size will occur extra incessantly than one other modal value.
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 reduce strip comprises a first Y-shaped construction including Filling cut tobacco 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 3rd Y-shaped construction branches off.
