Embodiment 2

[0063] The manufacturing system of Example 2 has two slurry laminators 4 , and a powder disperser 22 is disposed between these laminators 4 . According to this manufacturing system, a cover sheet C is also formed on the bottom plate M, that is, the tobacco powder layer B. As shown in FIG. The cover sheet C is the same slurry laminated sheet as the carrier sheet A. Therefore, when the bottom plate M passes through the downstream laminator 4, as Figure 8 and Figure 9 As shown, the bottom plate M forms a three-layer structure, and the tobacco powder layer B is sandwiched between the holding sheet A and the cover sheet C.

[0064] In the case of the bottom plate M with a three-layer structure, the weight of each of the holding sheet A and the cover sheet C is 3 to 50 g / m 2 eg 9g / m 2 , the level of tobacco powder layer B is 30 ~ 200g / m 2 For example 132g / m 2 . The weight ratio of binder powder to tobacco leaf powder in the mixed powder is 10 to 90. The arrangement of the ...

Abstract

Sheet tobacco according to the present invention includes a carrier sheet made of nonwoven plant fibers, and a tobacco powder layer formed on the carrier sheet and containing a powder mixture of tobacco lamina powder and binder powder. In a sheet tobacco manufacturing process according to the present invention, a carrier sheet of plant fibers is formed by a nonwoven fabric production process, a tobacco powder layer is formed by spreading the powder mixture on the carrier sheet, and a cover sheet of plant fibers is optionally formed on the tobacco powder layer. Subsequently, the carrier sheet, the tobacco powder layer and the optical cover sheet are all together subjected to heating and pressing, thereby producing sheet tobacco with a two- or three-layer structure. The present invention also provides a manufacturing system for carrying out the sheet tobacco manufacturing process.

Description

technical field [0001] The present invention relates to a tobacco sheet for use as a shredded filler material for cigarettes or filter cigarettes, and to a method and system for its manufacture. Background technique [0002] Typically, such tobacco sheets are produced by one of calendering, papermaking or pulping. Each of these methods has advantages and disadvantages, however, whichever method is used, the tobacco sheet produced has a lower bulk. [0003] In addition, Japanese Patent Publication No. 56-19225 discloses a method for producing a tobacco sheet having high bulkiness. This known production method utilizes nonwoven fabric production technology. First, a sheet-like base is formed from fibrous tobacco material, and then the formed base is impregnated with a liquid binder to produce a tobacco sheet. [0004] In order to use the above-mentioned nonwoven fabric manufacturing technology, the tobacco raw material must be a fiber of a predetermin...
