[0002] Tobacco sheet is also called reconstituted tobacco, homogenized tobacco and the like, which is made of tobacco scraps, tobacco dust, tobacco stems or low-grade tobacco leaves, with adhesive and other additives, and is processed into a man-made tobacco sheet. The tobacco sheet can be used as a raw material of tobacco products to replace natural cigar inner leaf to make cigars, or is cut into tobacco shreds to be used as raw materials of cigarettes. The tobacco sheet used as the cigar inner leaf is rolled into a disc shape, and the tobacco sheet used as the raw material of cigarettes is cut into a fine thread shape. The tobacco sheet is made of low-grade tobacco raw materials and leftover materials, which has the advantages of low cost, good filling property and reduction of tar content in smoke, and has been widely used in tobacco product production. At present, the papermaking method, the thick slurry method and the roll pressing method are commonly used in the tobacco sheet manufacturing field, especially the roll pressing method, which is most suitable for the requirements of the new tobacco process.

[0003] The roll pressing method for manufacturing the tobacco sheet is based on the principle that the tobacco sheet slurry is extruded into a sheet shape by using a pressing roller.
