In addition, a second couple of blends was used, that contained 70 % by weight of natural tobacco particles and 30 % by weight of reconstituted tobacco particles cut in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the reduce width of a person minimize strip is taken on the point along the length of the strip that yields the most important cross-sectional area. Further, the filling energy of the shredded first tobacco material could be maximised by deciding on an appropriate first reduce specification. This leads to an improved filling energy of the cut filler as an entire, notably when the primary tobacco materials is blended with at least one other tobacco materials.
In most well-liked embodiments, the first tobacco material is a pre-processed tobacco material. By “pre-processed tobacco materials” reference is made all through the specification to a tobacco materials produced by man from pure tobacco versus occurring naturally as such. It would due to this fact be fascinating to provide an alternate tobacco reduce filler having improved filling power. At the same time, it will Filling cut tobacco be fascinating to offer a novel process for manufacturing tobacco reduce filler, whereby the filling power of the tobacco cut filler is improved and the manufacturing of tobacco dust is decreased. The present invention relates to the manufacturing of tobacco cut filler comprising reconstituted tobacco and to a smoking article formed from a tobacco rod comprising the reduce filler in accordance with the invention.
Figures 1 to 12 exhibits reduce strips of a primary tobacco materials for incorporation in a reduce 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 first minimize specification, wherein the primary cut specification units a predetermined first reduce width CW1 and a predetermined first minimize length CL1 . In addition, the first minimize specification might further set a predetermined first sectional minimize width SCW1.
A tobacco reduce filler according to any one of many preceding claims, whereby the first tobacco materials is shredded into strips having a cut size from about 5 mm to about 60 mm. A tobacco reduce filler according to any certainly one of claims 2 to four, wherein the second tobacco materials is a natural tobacco leaf materials. An angle of 90 levels was thought of to be undesirable, in that it will lead basically to a form fairly much like the shape of Figure 6, and so an angle of 60 levels was chosen for the “V” parts. Further, the strategy preferably comprises the step of mixing the reduce first tobacco material and the reduce second tobacco material.
Further, the second Y-shaped construction includes a second branching node from which a rectangular structure branches off. In the embodiment of Figure 1 1 , the cut strip contains a first Y-shaped construction together with a primary branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped construction includes a second branching node from which a 3rd Y-shaped structure branches off.
The values of filling energy are expressed when it comes to corrected cylinder quantity which is the cylinder quantity of the tobacco materials at a reference moisture degree of 12.5 % oven volatiles. The cylinder volume could additionally be decided utilizing a Borgwaldt densimeter DD60 or DD60A kind fitted with a measuring head for minimize tobacco and a tobacco cylinder container. The term “sinusoidal” is used to describe a reduce strip of tobacco materials shaped substantially like a portion of a sine wave.
