ない等の欠点があった。However, in the conventional folding device, since the folding board 111 is a plate member fixed, friction with the web Y traveling along the folding board 111 is large, and the web Y is often broken. There was an accident such as breaking. For this reason, there are drawbacks in that it cannot be folded at a particularly high speed, and it is not suitable for manufacturing a tissue using a soft web.

As shown in FIG. 1 (A), the end surface 1a of the folding roller 1 on the free end side is aligned with the fold line L of the web W, and the web W on the exit side is moved in the traveling direction as shown in FIG. Tension f
When applied, the web W1 which is bent in an eight shape and is not in contact with the roller 1 of the running web W is about to be folded at a right angle. The position where this folding starts is always constant, which is the position P directly below the end face 10 of the folding roller 1. Therefore, it is always folded from the polygonal line L. When the portion of the web W1 which is not in contact with the roller 1 is pressed by the holding plate 2 on the exit side of the roller 1, the web W1 is completely folded on the web W0. As described above, in the present invention, the folding can be performed at the same position at all times, and the folding roller 1 is rotatable, so that the friction with the web W is small and the web is not torn. Therefore, it is suitable for high-speed folding and soft web folding.
