Suitable pure tobacco leaf materials embrace tobacco lamina, tobacco stem material and tobacco stalk materials. The pure tobacco leaf materials used because the second tobacco materials may include any type of tobacco leaf, together with for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco minimize filler according to the current invention contains a primary tobacco materials minimize in accordance with a first reduce specification, whereby the first cut specification sets no less than predetermined first cut width and first cut size. The term “filling energy” is used to explain the amount of area taken up by a given weight or mass of a tobacco material. The greater the filling power of a tobacco material, the decrease the weight of the fabric required to fill a tobacco rod of ordinary dimensions.
Figures 1 to 12 reveals cut strips of a primary tobacco material for incorporation in a minimize filler according to 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 cut specification, wherein the first reduce specification units a predetermined first cut width CW1 and a predetermined first cut size CL1 . In addition, the first minimize specification could further set a predetermined first sectional reduce width SCW1.
The minimize width of 1 such Y-shaped strip corresponds substantially to the distance between the ends of the second and third strip portions as measured alongside a direction perpendicular to the course outlined by an axis of the first strip portion. Within the same Y-shaped strip, the sectional cut width of each strip portion may instead tobacco pipe be measured along a course substantially perpendicular to the axis of every strip portion. In some circumstances, such as the place the minimize strip of tobacco materials is substantially rectangular , the sectional minimize width and the strip cut width are the identical.
In most well-liked embodiments, the first tobacco material is shredded into strips from a sheet material having a thickness from about zero.05 mm to about 1 mm. Even more preferably, the first tobacco materials is shredded into strips from a sheet material 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 minimize filler in accordance with any considered one of claims 1 to 9, wherein the first tobacco material is shredded into strips every comprising a minimum of a first strip structure comprising a branching node from which an extra strip construction branches off, forming an angle with the primary strip construction. Figures 10 and 12 present two examples of reduce strips including a quantity of V-shaped construction. Each V construction contains two considerably straight elements forming an angle.
By contrast, in a multimodal distribution, the chance mass perform has a quantity of maxima, which means that among the minimize strips of the primary tobacco materials there are a quantity of values of minimize length that happen most frequently. In the context of the current specification, a distribution having a number of local maxima is considered multimodal. It might be appreciated that the totally different modes in a multimodal distribution may also have completely different frequencies, such that, among the reduce strips of the first tobacco materials, one modal value of reduce length will happen extra incessantly than one other modal value.
Alternative strategies for the manufacture of reconstituted tobacco sheets are additionally recognized to the skilled particular person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to check with a web, preferably with considerably uniform thickness, that may be produced by the rolling or casting of an aqueous slurry or pulp formed Filling cut tobacco from tobacco particles by certainly one of a number of methods known in the art. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced during the manufacturing process.
