Reference numeral 2 denotes a rotation shaft that is rotatably mounted by a drive source (not shown) such as a motor of this flat-wound paper tube manufacturing apparatus. This rotation shaft 2 has a longitudinally long notched groove 3 formed therein. Two sheets of base paper forming a paper tube are arranged parallel to this rotating shaft 2 and at right angles to this rotating shaft 2 so as to be transportable. That is, the roll 4 is wound with one base paper, and the roll 4' is wound with the other base paper. The base paper of the roll 4 has a paper grain parallel to the axial direction of the rotating shaft 2, and the other base paper of the roll 4' has a paper grain that is perpendicular to the axial direction of the rotating shaft 2. The roll core 5 of one roll 4 is disposed perpendicular to the rotation axis 2, and the roll core 5 of the other roll 4 is disposed parallel to the rotation axis 2. Both base papers rewound and sent out from each roll 4, 4' intersect near a predetermined position of the rotating shaft 2. 6, 6' are tension rollers, 7,
7' is a main drive roller, and 8 and 8' are auxiliary drive rollers. Further, 9, 9' are glue rollers, and these rollers 9, 9' are arranged so that a part of the rollers is immersed in containers 10, 10' containing glue. By rotating ', glue can be applied to one side of the base paper. 12,1
2' is an auxiliary roller, which is similar to the above-mentioned gluing roller 9,
Together with 9', this serves to sandwich the base paper and assist in gluing the base paper, as well as to feed the base paper. Further, 11 and 11' are glue scraping tools, which remove excess glue adhering to the rollers 9 and 9' from the containers 10 and 1.
It scrapes off within 0'. Reference numerals 13 and 13' designate rollers for temporarily avoiding a stop when the cutter cuts the base paper to a desired size. Also 14,1
Reference numeral 4' denotes a base paper feed roller, and an annular convex portion 15, 15' is formed on its surface to prevent the base paper with glue from adhering to the roller surface as much as possible and to feed it smoothly. being considered. 16, 16' are rollers 14, 1 that sent the base paper
This is a cutter disposed in front of roller 4', and is used to cut both base papers sent out from rollers 4 and 4' into desired dimensions. The base paper sent out from the roller 4 is moved in the flow direction of the base paper, that is,
The cutter 16 automatically cuts the base paper so that the length of the base paper corresponds to the length of the paper tube when wound. Further, the cutting dimension in the length direction of the base paper sent out from the roll 4' is cut so as to be the same as the width dimension of the base paper sent out from the roll 4.
そして、裁断された上記両原紙は、重なり合つ

作をくり返し、順次紙管を形成する。 FIG. 2A shows that the vertically grained raw paper fed out from the roll 4 and cut (in the following explanation, the raw paper having grains parallel to the axial direction of the rotating shaft 2 is referred to as the vertically grained raw paper) is rotated. It is shown engaged with the notched groove 3 of the shaft 2 and set in a predetermined position. From this state, as shown in FIG. 2B, the rotation shaft 2 rotates once,
When the vertical grain paper is wound around the rotating shaft 2 once,
Between the rotary shaft 2 and the vertical grain paper, the horizontal grain raw paper fed from the roll 4' and cut by the cutter 16 (in the following explanation, the paper grain perpendicular to the axial direction of the rotary shaft 2) A base paper having a grain size (referred to as a horizontal grain base paper) is inserted. As shown in Figure 2C, the vertical grain paper and the horizontal grain paper are simultaneously wound around the rotating shaft 2, and as shown in Figure 2D, the vertical grain paper and the horizontal grain paper are alternately wound to form a stacked paper tube. Ru. Then, the formed paper tube is attached to the rotating shaft 2 by a hook (not shown).
be extracted from. Thereafter, the above-described series of operations is repeated again to sequentially form paper tubes.

After stacking the rotation axis 2 at the same time,
You are free to change the design so that it can be wound around. In addition, either the vertically grained paper fed out from the roll 4 and cut, or the vertically grained paper fed out and cut from the roll 4', is all wound around the rotating shaft 2 first, and then the paper is wound from above. It is also possible to wind a vertically grained base paper or a horizontally grained base paper opposite to the base paper to form a paper tube in which a vertically grained base paper layer group and a horizontally grained base paper layer group are layered.
