The reduce width of 1 such Y-shaped strip corresponds considerably to the space between the ends of the second and third strip portions as measured alongside a path perpendicular to the path defined by an axis of the first strip portion. Within the same Y-shaped strip, the sectional reduce width of every strip portion might as a substitute be measured alongside a direction substantially perpendicular to the axis of each strip portion. In some circumstances, similar to where the reduce strip of tobacco material is substantially rectangular , the sectional minimize width and the strip reduce width are the same.
Without wishing to be sure to theory, will probably be appreciated that in any chopping, rolling or extruding operation, the tobacco fibres typically align in a given path, which may thus be identified as the longitudinal direction of the tobacco materials. The “minimize size” of a reduce strip of tobacco material for incorporation in minimize fillers in accordance with the current invention may subsequently be measured along the principle direction of fibre alignment, which generally corresponds to the longitudinal direction. Thus, the minimize length of an individual minimize strip could be precisely measured utilizing a conventional measuring system under a microscope. In a traditional course of, reconstituted tobacco or tobacco stem materials or both are typically blended with threshed tobacco lamina to endure a sequence of therapies, corresponding to conditioning and drying. To this function, a reconstituted tobacco sheet is usually ripped into randomly formed sheet-like items having a non-uniform size, usually of several square centimetres.
The values of filling power are expressed when it comes to corrected cylinder quantity which is the cylinder volume of the tobacco materials at a reference moisture stage of 12.5 % oven volatiles. The cylinder quantity may be decided using a Borgwaldt densimeter DD60 or DD60A sort fitted with a measuring head for reduce tobacco and a tobacco cylinder container. The term “sinusoidal” is used to explain a minimize strip of tobacco materials formed substantially like a portion of a sine wave.
A tobacco cut filler in accordance with any one of the previous claims, whereby the primary tobacco materials is a reconstituted tobacco sheet. Preferably, the reduce filler has a filling power of at least about three.5 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. More ideally, the reduce filler has a filling power of at least about 4 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. In addition, or in its place, the cut filler preferably has a filling energy of lower than about 8 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles.
Alternative methods for the manufacture of reconstituted tobacco sheets are also recognized to the expert person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to refer to a web, preferably with considerably uniform thickness, that could be produced by the rolling or casting of an aqueous slurry or pulp fashioned Fashion tobacco pipe from tobacco particles by certainly one of a number of methods identified in the art. Suitable by-products include tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced through the manufacturing course of.
A tobacco minimize filler according to any one of many preceding claims, wherein the first tobacco material is shredded into strips having a reduce length from about 5 mm to about 60 mm. A tobacco reduce filler in accordance with any one of claims 2 to 4, wherein the second tobacco materials is a natural tobacco leaf material. An angle of ninety degrees tobacco pipe was thought-about to be undesirable, in that it would lead primarily to a shape quite much like the form of Figure 6, and so an angle of 60 levels was chosen for the “V” elements. Further, the tactic ideally includes the step of mixing the cut first tobacco material and the minimize second tobacco materials.
