Some have a filter element having a structure as shown in Japanese Patent Laid-Open No. That is, as shown in FIG. 3, a sheet of paper is fold-folded to form a large number of fold ridges, but the fold ridge piece 1a at one end is joined to the fold ridge piece 1b that is adjacent to the fold piece, and The fold piece 1b at the end and the adjacent fold piece 2a are joined together, and both ends of this piece are joined together to form an annular body. As shown in FIG. 4, the filter element having this structure is formed by fold-folding the paper body 3 having folds. The paper body 3 has a rectangular shape,
It has pleated fold lines 4 and 5 alternately at predetermined intervals. The fold line 4 is a triangle fold line 4a, 4b that widens toward one end.
And the fold line 5 has a triangular fold line extending toward the other end side.
It has 5a and 5b. The length l 1 of the base of each triangle crease line,
l 2 is set so that l 1 > l 2 . An adhesive layer 6 having a predetermined width is provided on the surface on one end side of the paper 3, and a contact layer 7 having a predetermined width is provided on the back surface on the other end side. The filter element is formed by folding the paper body 3 into a ring-shaped body.

いる。(Problems to be Solved by the Invention) Since the paper body 3 is pleated to form an annular body having different inner and outer diameters, it is provided with pleated folds having the relationship of l 1 > l 2 above. There is a need. Therefore, the sheet of paper 3
Is folded by a pleat folding machine (not shown), and when it continuously comes out of the folding machine, it becomes a fan shape instead of a rectangular shape (Fig. 5). Then, when the paper body 3 is moved on-bearing from the fold-folding machine to the next work machine, the structure does not go straight and causes a problem in production.

The lengths of the bases of the triangular portions surrounded by the triangular fold lines on one end side and the lengths of the bases of the triangular portions surrounded by the triangle fold lines on the other end side are substantially the same. It was a paper body.

Since they are substantially the same, even when the paper body is folded along the fold line, the obtained product does not have a fan shape but has a rectangular shape in which both ends of the paper body are substantially parallel. When the fold-folded paper body is formed into an annular shape, the triangular portion on the inner peripheral side is compressed and deformed, but is not damaged.

は、たとえばホットメルト樹脂により形成される。(Embodiment) FIG. 1 shows an overbody 10 showing an embodiment of the present invention, which is formed by forming a fold in a rectangular paper 11. The folds are
It consists of pleated fold lines 12, 13 and triangular fold lines 12a, 12b, 13a, 13b and auxiliary fold lines 14. The pleat fold lines 12 and 13 are alternately provided at a predetermined interval, and the pleat fold line 12 is formed with two triangular fold lines 12a and 12b that continuously extend toward one side wall of the paper 11 and the pleat fold lines 12 and 13 are also formed. The fold line 13 is formed with two triangular fold lines 13a and 13b extending toward the other end of the paper 11. The length l 1 of the base of the triangular portion surrounded by the triangular fold lines 12a and 12b and the length l 2 of the base of the triangular portion surrounded by the triangle fold lines 13a and 13b are substantially the same. Set to be length. Triangular fold line 13a, 1 at the other end of paper 11
An auxiliary fold line 14 extending inward from the bottom side for a predetermined length is provided on the bottom side of the triangular portion surrounded by 3b.
Such a paper body 10 is provided with an adhesive coating layer 15 with a predetermined width on the back surface at one end and an adhesive coating layer 16 with a predetermined width on the other end surface. Adhesive coating layers 15, 16
