摘要： PROBLEM TO BE SOLVED: To provide both a method for transporting capable of reducing clogging of a shred tobacco layer at a shoe and a tongue of a winding pipe part, stabilizing a production process and product qualities and reducing a manufacturing cost and an apparatus for the method. SOLUTION: A shred tobacco layer T is adsorbed on a tobacco band 8 having a great number of holes, adsorbing shred tobacco on its under surface, holding and transporting the shred tobacco. The cross-sectional shape of the shred tobacco layer at a face perpendicular to the advance direction of the tobacco band 8 is made in such a way that the shred tobacco layer T is formed so as to widen the shred tobacco layer T in the cross-section with increase in the thickness of the shred tobacco layer from the tobacco band 8. The shred tobacco is transported to a winding pipe part to compress the shred tobacco layer T in an approximately circular section.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a cigarette, capable of easily improving the winding hardness of the cigarette without requiring specific process and facilities, and a cigarette production unit. SOLUTION: This method for producing the cigarette is provided by forming a chopped tobacco layer TL by sucking the chopped tobacco T with a tobacco band 2, conveying the chopped tobacco layer TL accompanying with its traveling, on the one hand, traveling a winding paper P through a compression forming passage 10 and loading the chopped tobacco layer TL sent out from the tobacco band 2 on the winding paper P for compression forming as a prescribed form. Since the traveling speed of the tobacco band 2 is increased relatively based on the traveling speed of the winding paper P, the arrangement of the chopped tobacco layer TL is changed.

摘要： PROBLEM TO BE SOLVED: To enable the measurement of the amount of the diametrical distortion of cut tobacco by making up a cylindrical container whose diameter is freely enlargeable from a plurality of container frames and a compressing rod, compressing cut tobacco in the container, measuring the amount of axial distortion, and obtaining the amount of the movement of the container frames at the time when the diameter of container is enlarged and the stress exerted on the container frames becomes zero. SOLUTION: A cylindrical container 2 is formed with a container frame 1 as the minimum inner circumferential location, and a predetermined amount of cut tobacco is inserted into it. A compressing rod 9 is lowered by a crosshead controlling part to compress the cut tobacco in the axial direction of the cylindrical container 2 under a predetermined load. A pressure sensor 5 detects a laterally displacing force exerted from the cut tobacco to the container frame 1, and a container frame supporting body 3 is moved by a lateral displacement controlling part to a location where stress becomes zero. A location detecting device 8 obtains the amount of displacement of the container frame 1 at the time when stress becomes zero, and it is taken as the amount of lateral distortion of the cut tobacco and outputted with the amount of vertical distortion exerted on the cut tobacco by the compressing rod 9. By this, it is possible to efficiently measure the Poisson's ratio of compression of the cut tobacco.

摘要： PROBLEM TO BE SOLVED: To provide the cut tobacco-feeding device of a tobacco-rolling machine, capable of uniforming the cross-sectional hardness (elastic modulus) of a cigarette without related to its direction and capable of improving the uniformity of the rolling hardness. SOLUTION: A tobacco hand driven and extensively spanned between a chimney portion 5 and a pipe-winding portion 3 comprises two endless belts 6a, 6b disposed in parallel to each other. The lateral directions of the endless belts and their cross-sectional shape are changed by the use of guides 13, 14, 15 disposed on the back surfaces of the endless belts 6a, 6b. The layer of a cut tobacco Tk adsorbed to the surface of the endless belt is rounded into a bar-like shape, thereby randomizing the arrangement directions of the cut tobacco and feeding the randomized cut tobacco into the pipe-winding portion. The excessive part of the cut tobacco adsorbed to the surfaces of the endless belts 6a, 6b is cut off with a trimming disk 9 to adjust the amount of the adsorbed cut tobacco, and the layer of the cut tobacco is subsequently rounded by the control of the cross-sectional shape of the endless belts 6a, 6b.

摘要： PROBLEM TO BE SOLVED: To prevent tobacco from slipping off from the tip without causing movement and slip of cut tobacco in rolled paper and prevent breaking of cut tobacco and dispersion of packed density by providing a means for increasing abrasion coefficient with cut tobacco in the inside of rolled paper. SOLUTION: This cigarette is obtained by providing many protruded parts 10 for increasing abrasion coefficient with cut tobacco on the inside of rolled paper 4. These protruded parts 10 are obtained by subjecting at least the top of cigarette, preferably whole area of rolled paper 4 to embossing finish. The embossing finish area preferably has air permeability larger than that of rolled paper 4 at the stage before carrying out embossing finish.
