Reconstituted tobacco is shaped from tobacco materials corresponding to tobacco stems, tobacco stalks, leaf scraps and tobacco mud, which are produced during the manufacturing processes of tobacco products. Such tobacco materials might, for instance, be ground to a fine powder and then combined with water and sometimes with a binder, corresponding to guar gum, to type a slurry. This slurry is then cast onto a supportive floor, corresponding to a belt conveyor, and dried to kind a sheet (so known as ‘forged leaf) that can be faraway from the supportive surface and wound into bobbins.
Figures 1 to 12 reveals reduce strips of a first tobacco materials for incorporation in a minimize filler in accordance with the present invention. The strips have been cut from a sheet of reconstituted tobacco having a thickness from about 0.05 mm to about 1 mm in accordance with a primary minimize specification, wherein the primary cut specification units a predetermined first minimize width CW1 and a predetermined first reduce length CL1 . In addition, the first cut specification may additional set a predetermined first sectional cut width SCW1.
A tobacco minimize filler in accordance with any one of the previous claims, wherein the primary tobacco material is shredded into strips having a cut length from about 5 mm to about 60 mm. A tobacco reduce filler in accordance with any one of claims 2 to four, wherein the second tobacco material is a pure tobacco leaf materials. An angle of 90 levels Fashion tobacco pipe was thought-about to be undesirable, in that it will lead primarily to a shape quite just like the form of Figure 6, and so an angle of 60 degrees was chosen for the “V” elements. Further, the method preferably comprises the step of blending the minimize first tobacco materials and the cut second tobacco material.
A tobacco cut filler based on any one of the previous claims, whereby the first tobacco materials is a reconstituted tobacco sheet. Preferably, the minimize filler has a filling power of no much less than about 3.5 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. More preferably, the reduce filler has a filling energy of at least about 4 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles. In addition, or as an alternative, the reduce filler ideally has a filling power of less than about eight cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles.
These irregular items are intended to be related in measurement to tobacco lamina, such that they are often blended with the tobacco lamina and minimize. In particular, the blend is often reduce into particles having a predetermined minimize width. However, as a end result of the reconstituted tobacco sheet is quite randomly ripped into items, the tobacco fibres are generally not aligned in a uniform course. Tobacco rods had been prepared from a tobacco cut filler utilizing tobacco particles reduce in accordance with the specifications of Figures 1 1 and 12. In specific, a primary couple of blends had been used, that contained eighty five p.c by weight of natural tobacco particles and 15 p.c by weight of reconstituted tobacco particles minimize in accordance with specifications of Figures 1 1 and 12, respectively.
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 substantially uniform thickness, that might be produced by the rolling or casting of an aqueous slurry or pulp formed tobacco pipe from tobacco particles by one of a quantity of methods identified within the art. Suitable by-products embody tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced through the manufacturing course of.
The cut width of one such Y-shaped strip corresponds considerably to the space between the ends of the second and third strip parts as measured along a direction perpendicular to the course defined by an axis of the first strip portion. Within the identical Y-shaped strip, the sectional minimize width of each strip portion could instead be measured along a path considerably perpendicular to the axis of each strip portion. In some cases, corresponding to the place the cut strip of tobacco materials is substantially rectangular , the sectional reduce width and the strip cut width are the same.
