The reduce width of 1 such Y-shaped strip corresponds considerably to the gap between the ends of the second and third strip portions as measured alongside a path perpendicular to the course defined by an axis of the primary strip portion. Within the identical Y-shaped strip, the sectional minimize width of each strip portion may as an alternative be measured alongside a direction substantially perpendicular to the axis of each strip portion. In some cases, similar to the place the minimize strip of tobacco material is substantially rectangular , the sectional cut width and the strip minimize width are the same.
Where OV is the precise percent oven volatiles of the sample of tobacco cut filler and f is a correction issue (0.four for the test indicated). In RYO, the stem can either be separated from the lamina by hand (for hand-stripped tobacco) or the stem and lamina aren’t separated in any respect (loose-leaf tobacco) – this kind is used for Scandinavian Tobacco Group’s Norwegian RYO brand Tiedemanns. A method according to any considered one of claims 15 to 20, further comprising adjusting the moisture content material of the second tobacco materials. A fishbone-shaped strip is shown in Figure 6, whereas Figures 7 and eight present two embodiments of rectangular strips. Abstract The amount of tobacco which is necessary for the proper filling of a cigarette is dependent upon different factors and notably on the filling weight of tobacco rag at a given strain. Some years ago the ”Centre d’Essais” of the SEITA developed an equipment by which the filling weight being associated to the filling capacity can be measured.
Before every measurement was taken, tobacco particles reduce in accordance with the various cut specifications were saved in a conditioned room for twenty-four hours. For every specification, three measurements of the CCV have been taken on the 5 samples, after which the entire common was calculated and assumed as the effective CCV of the specification. Between repetitions of the measurements, the samples were prepared by detangling the person strands, so that any compaction occurred during the previous measurement would have as little influence as potential on the subsequently measured CCV. In some embodiment, the minimize length distribution among the cut strips of the primary tobacco materials is preferably unimodal.
Reconstituted tobacco is shaped from tobacco materials such as tobacco stems, tobacco stalks, leaf scraps and tobacco dust, that are produced in the course of the manufacturing processes of tobacco merchandise. Such tobacco material may, for example, be ground to a fine powder and then mixed with water and usually with a binder, similar to guar gum, to form a slurry. This slurry is then cast onto a supportive surface, similar to a belt conveyor, and dried to type a sheet (so called ‘solid leaf) that can be faraway from the supportive surface and wound into bobbins.
Figures 1 to 12 reveals reduce strips of a primary tobacco materials for incorporation in a cut 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 first reduce specification, whereby the first reduce specification units a predetermined first minimize width CW1 and a predetermined first cut length CL1 . In addition, the primary minimize specification could further set a predetermined first sectional minimize width SCW1.
The thickness therefore corresponds substantially to the thickness of the tobacco material fed to the chopping or shredding apparatus. The thickness of a person reduce strip may be measured using a standard measuring device underneath a microscope. In some embodiments, the thickness of a tobacco material forming the reduce strip may be substantially constant. In different embodiments, the thickness of the tobacco materials forming the reduce strip may range along the longitudinal direction, alongside a path perpendicular to the longitudinal direction, or alongside both. The thickness of an individual reduce strip is measured at the level along the longitudinal path of slicing that yields the most important cross-sectional space.
In particular, one such strip could comprise a minimum of a first strip construction comprising a branching node from which an additional strip structure branches off, forming an angle with the primary strip structure. The moisture content material of the tobacco reduce filler is expressed herein as “% oven volatiles”, which is determined by measuring the percentage weight reduction Filling cut tobacco from the minimize filler upon drying the fabric in an oven at 103 levels Centigrade (°C) for a hundred minutes. It is assumed that a major majority of the load loss from the cut filler outcomes from the evaporation of moisture. A method in accordance with any considered one of claims 15 to 17, whereby the second tobacco materials is a reconstituted tobacco sheet.
The values of filling power are expressed in phrases 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 may be decided using a Borgwaldt densimeter DD60 or DD60A kind tobacco pipe fitted with a measuring head for reduce tobacco and a tobacco cylinder container. The time period “sinusoidal” is used to explain a cut strip of tobacco material shaped considerably like a portion of a sine wave.
Without wishing to be sure to concept, will in all probability be appreciated that in any chopping, rolling or extruding operation, the tobacco fibres typically align in a given course, which can thus be identified as the longitudinal direction of the tobacco material. The “cut length” of a reduce strip of tobacco materials for incorporation in cut fillers in accordance with the present invention may subsequently be measured along the primary direction of fibre alignment, which generally corresponds to the longitudinal direction. Thus, the minimize size of a person reduce strip may be precisely measured utilizing a traditional measuring system under a microscope. In a standard course of, reconstituted tobacco or tobacco stem material or both are sometimes blended with threshed tobacco lamina to endure a sequence of treatments, corresponding to conditioning and drying. To this function, a reconstituted tobacco sheet is typically ripped into randomly shaped sheet-like pieces having a non-uniform size, typically of a quantity of sq. centimetres.
In addition, a second couple of blends was used, that contained 70 % by weight of pure tobacco particles and 30 % by weight of reconstituted tobacco particles cut in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the minimize width of an individual minimize strip is taken on the level alongside the length of the strip that yields the most important cross-sectional area. Further, the filling power Fashion tobacco pipe of the shredded first tobacco material may be maximised by deciding on an appropriate first cut specification. This results in an improved filling energy of the minimize filler as a complete, particularly when the primary tobacco materials is blended with no less than one other tobacco material.
