Conventionally, cut filler tobacco merchandise for smoking articles are shaped predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf throughout a threshing process. Much of the stem portion that continues to be after the lamina has been eliminated and separated just isn’t used. However, it is not uncommon to add some tobacco stems back into the reduce filler along with the lamina.
The yield of flat rolled stem which may be used instantly as filler is elevated, and the common stem length and thus the common length of minimize filler from stem is elevated. A tobacco minimize filler in accordance with any one of many preceding claims having a filling power of no much less than three.5 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles. Accordingly, tobacco particles were prepared from the same sheet of reconstituted tobacco based on the reduce specification illustrated in Figure 12, whereby the reduce width SCW1 is of zero.9 millimetres, the minimize size CL1 is of four.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
Sensors 40 and mass move controllers forty two, forty four, if current, are operatively linked with a management unit forty six configured to regulate the operation of the equipment. In particular, the control unit 46 adjusts the pace to the conveyor belt 38 in view of variations in the speed at which the net of reconstituted tobacco is fed to the shredding device 36, so as to prevent any undesirable accumulation of minimize strips on the conveyor belt. By finely controlling the size and shape of the strips into which the first tobacco materials is minimize or shredded, the options of the primary tobacco material can advantageously be higher preserved every time the first tobacco materials is blended, in the shredded state, with another tobacco materials. This is especially advantageous when the primary tobacco material is a pre-processed tobacco material, such as a reconstituted tobacco sheet material. The “thickness” of a cut strip of tobacco materials for incorporation in reduce fillers according to the current invention refers back to the distance between an upper floor and a lower floor of the portion of material forming the cut strip.
In preferred embodiments, the first tobacco material is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even more preferably, the primary tobacco material is shredded into strips from a sheet material having a thickness from about zero.1 mm to about 0.three mm, most ideally from a sheet materials having a thickness of about 0.2 mm. A tobacco reduce filler in accordance with any considered one of claims 1 to 9, wherein the primary Fashion tobacco pipe tobacco materials is shredded into strips every comprising at least a primary strip structure comprising a branching node from which a further strip structure branches off, forming an angle with the primary strip structure. Figures 10 and 12 show two examples of cut strips including one or more V-shaped construction. Each V structure contains two substantially straight parts forming an angle.
Suitable natural tobacco leaf materials embody tobacco lamina, tobacco stem materials and tobacco stalk material. The pure tobacco leaf material used because the second tobacco material may embrace any sort 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 reduce filler according to the present invention includes a primary tobacco materials reduce in accordance with a primary reduce specification, whereby the first cut specification sets at least predetermined first cut width and first reduce length. The time period “filling energy” is used to explain the amount of space taken up by a given weight or mass of a tobacco materials. The larger the filling power of a tobacco material, the decrease the weight of the material required to fill a tobacco rod of ordinary dimensions.
Even more preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of a minimal of about 0.2 mm. In addition, or in its place, the first tobacco materials is preferably shredded into strips from a sheet materials having a thickness of less than about 1 mm. More ideally, the first tobacco material is shredded into strips from a sheet materials having a thickness of lower than about 0.ninety five mm. Even more preferably, the primary tobacco materials is shredded into strips from a sheet material having a thickness of lower than about zero.85 mm.
In turn, the third Y-shaped construction comprises a third branching node from which an oblong structure branches off. In the embodiments of both Figures 9 and 1 1 the sectional reduce width inside all of the constructions forming the minimize strips is considerably constant. By means of example, in a Y-shaped strip it is potential to establish a primary strip portion extending along a primary path and a second and third strip portions extending from the primary strip parts along diverging directions, in order that they kind an angle.
In the embodiment of Figure 10, the 2 straight components are considerably perpendicular. The minimize strip of Figure 12 could additionally be thought to be comprising three V-shaped buildings of the type illustrated in Figure 1 , whereby adjoining V-shaped structures are connected by the ends of respective straight parts. In the embodiments of both Figures 10 and 12 the sectional minimize width within all the constructions forming the reduce strips is substantially tobacco pipe fixed. A tobacco reduce filler based on any one of many previous claims, wherein the reduce length distribution among the reduce strips of the first tobacco material is ideally unimodal. By method of example, the minimize strip of Figure 9 contains a primary Y-shaped construction including a first branching node from which a second Y-shaped construction branches off.
In apply, one such reduce strip may be described as roughly wave-shaped or zigzag-shaped. Accordingly, geometric parameters similar to the height amplitude, peak-to-peak amplitude, interval of a sine wave may be used to describe the shape of 1 such minimize strips. A tobacco cut filler contains a primary tobacco material minimize in accordance with a primary reduce specification, whereby the first reduce specification sets at least predetermined first cut width and first minimize length. A tobacco cut filler according to any one of the previous claims, wherein the first tobacco material is shredded into strips having a minimize width from about zero.2 mm to about 1 mm.
The term “minimize specification” is used all through the specification to discuss with the assorted geometric parameters characterising the strips obtained by subjecting a tobacco materials to a cutting operation. Thus, in accordance to a given “reduce specification”, a tobacco material shall be reduce or shredded into strips having a predetermined minimize width, cut length, reduce form and so forth. Further, it will be fascinating to supply Filling cut tobacco one such improved course of that permits for a greater control of the form, dimension and properties of the reconstituted tobacco matter forming a part of the reduce filler. At the identical time, it might be desirable to supply one such course of that doesn’t require any main modification of the conventional equipment and facilities used within the main treatment of tobacco.
