The term “cut specification” is used all through the specification to discuss with the assorted geometric parameters characterising the strips obtained by subjecting a tobacco material to a chopping operation. Thus, in accordance to a given “minimize specification”, a tobacco materials shall be cut or shredded into strips having a predetermined reduce width, minimize length, reduce shape and so forth. Further, it would be desirable to provide Filling cut tobacco one such improved course of that allows for a greater management of the form, measurement and properties of the reconstituted tobacco matter forming a part of the reduce filler. At the same time, it might be fascinating to provide one such course of that does not require any major modification of the traditional apparatus and services used within the main treatment of tobacco.
Experiments have been carried out so as to assess the influence of different shapes and minimize specifications to key parameters of tobacco minimize filler particles, such as the filling power. In more detail, 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 minimize strip, which considerably corresponds to the strip cut size divided by the number of repetitions of the zigzag or wave. For occasion, within the minimize 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, even more preferably from four mm to 10 mm. Preferably, the tobacco cut filler additional comprises a second tobacco material minimize in accordance with a second minimize specification differing from the first reduce specification for at least considered one of minimize length and reduce width.
Figures 1 to 12 shows cut strips of a primary tobacco materials for incorporation in a cut filler in accordance with the present invention. The strips have been reduce from a sheet of reconstituted tobacco having a thickness from about 0.05 mm to about 1 mm in accordance with a primary reduce specification, wherein the first cut specification sets a predetermined first cut width CW1 and a predetermined first reduce size CL1 . In addition, the first minimize specification could further set a predetermined first sectional reduce width SCW1.
More preferably, the primary tobacco material is shredded into strips having a minimize width of lower than about 0.95 mm. Even more ideally, the primary tobacco materials is shredded into strips having a minimize width of lower Fashion tobacco pipe than about zero.9 mm. In most well-liked embodiments, the first tobacco material is shredded into strips having a minimize width from about zero.2 mm to about 1 mm. Preferably, the second tobacco materials is a pure tobacco leaf materials.
In most popular embodiments, the primary tobacco material is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even more ideally, the first tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.1 mm to about 0.three mm, most ideally from a sheet material having a thickness of about zero.2 mm. A tobacco minimize filler in accordance with any one of claims 1 to 9, whereby the primary tobacco materials is shredded into strips every comprising at least a first strip structure comprising a branching node from which a further strip construction branches off, forming an angle with the first strip structure. Figures 10 and 12 present two examples of reduce strips together with one or more V-shaped construction. Each V construction comprises two considerably straight elements forming an angle.
A tobacco cut filler in accordance with any one of many previous claims, whereby the primary tobacco material is shredded into strips having a minimize size from about 5 mm to about 60 mm. A tobacco reduce filler in accordance with any certainly one of claims 2 to 4, wherein the second tobacco materials is a pure tobacco leaf material. An angle of ninety levels was thought-about to be undesirable, in that it will lead essentially to a form fairly similar to the form of Figure 6, and so an angle of 60 levels was chosen for the “V” parts. Further, the method ideally comprises the step of blending the minimize first tobacco materials and the reduce second tobacco material.
