用濾材の製造方法を提供することを目的とする。However, in the case of the above-mentioned manufacturing method, the filter medium for a zigzag air filter obtained is folded from the one side of the filter medium 1 because the filter medium 1 for passing air is folded at a constant interval. When the air that has entered is discharged from the other side of the filter medium 1, the air flow direction becomes orthogonal to the filter medium 1, and the predetermined air flow pressure cannot be obtained unless the pressure of the air that is passed through is increased. . On the other hand, the applicant of the present invention has proposed a method for manufacturing an air filter medium which reduces pressure loss because the direction of the filter medium is inclined with respect to the air flow direction, as disclosed in Japanese Patent Laid-Open No. 4-300612. . This manufacturing method is a method for manufacturing a zigzag air filter medium obtained by folding a filter medium made of a non-woven fabric in a zigzag manner, wherein a resin layer to be a space retaining material is applied and formed on at least the front and back surfaces of both sides of the filter medium sheet. While the filter medium is uncured, the folded part of the filter medium is sharply angled by sandwiching it between two pressing dies of triangular pressing dies that can advance and retreat without piercing each other and whose tips are opposite to each other. To form. However, the above-mentioned manufacturing method has a problem that a triangular die having an acute angle is required to form the folded portion of the filter medium at an acute angle, resulting in an increase in manufacturing cost. Therefore, the present invention provides a zigzag-shaped filter material for an air filter with less pressure loss, and in order to form the folded portion of the filter material at an acute angle, a special mold or the like is not required, and the resin layer to be the spacing member is formed. An object of the present invention is to provide a method for manufacturing a filter material for a zigzag-shaped air filter, which makes it possible to form the folded portion at an acute angle by utilizing pressing.

ではない。BEST MODE FOR CARRYING OUT THE INVENTION According to the manufacturing method of the present invention, a resin layer formed by coating on the outer side surface of the filter medium when folded can press the top portion of the adjacent filter medium. As described above, when the resin layer is applied and formed, the resin layer is applied and formed so that the thickness of the resin layer becomes thicker in the vicinity of the top of the filter medium. The resin layer is
The spacing material is applied and formed on at least both sides of the front and back surfaces of the filter material, and solidifies to form the spacing material. The formation of coating on both sides of the resin layer includes a method in which both sides of the front and back surfaces of the filter medium are linearly formed, and a case in which only the outer surface of the folded filter medium is linearly formed. As the resin layer, for example,
EVA resin, polyamide resin, polyester resin and the like can be used, but from the viewpoint of solidification during the manufacturing process, a hot-melt type resin such as polyester resin is preferable. Further, in the present invention, the resin layer is formed so as to be thicker near the top of the filter medium. As a method for coating and forming a resin layer having such a change in thickness, it is conceivable to control the injected resin layer to increase the thickness of the resin in the vicinity of the top of the filter medium. When the resin is applied while moving at a high speed, it is preferable to apply the resin layer in two steps so that the resin is easily applied to the vicinity of the top of the filter medium. It should be noted that the vicinity of the apex refers to less than 1/2 of the distance between the apex of the zigzag and the center line located between the apex and the valley of the zigzag. This is 1/2 the distance from the top of the zigzag to the centerline.
This is because when the resin layer is applied as described above, pressing force is less likely to be applied only to the tops of the adjacent filter media formed by the resin layer having the above thickness. Further, as the filter medium used in the present invention, for example, glass fiber, polyester,
It can be made of a nonwoven fabric such as polypropylene, but is not particularly limited as long as it has a filtering function.
