ルタ濾材の製造方法を提供することを目的とする。[Problems to be Solved by the Invention] However, in the case of the above manufacturing method, the zigzag-shaped air filter material obtained is formed in such a way that the filter materials a through which air passes are arranged in parallel at regular intervals, so that Since the airflow is parallel to the airflow d (in the direction of the arrow) passing through the air filter, the air entering from one side e of the filtering material a initially becomes the airflow d parallel to the filtering material a, but the airflow d is parallel to the filtering material a. In order for the airflow to be discharged from the other side f, the direction of the airflow d must cross the filtering medium a in a direction perpendicular to the filtering medium a. Since pressure cannot be obtained, there is a problem of high pressure loss. Therefore, the zigzag shape of the filter medium may be formed into a continuous mountain shape with a sharp tip or a sawtooth shape, but it has been difficult to form the filter medium into such a zigzag shape. An object of the present invention is to provide a method for manufacturing a zigzag air filter medium that eliminates such problems.

In the figures, 1 is a filter medium made of a nonwoven fabric such as glass fiber, polyester, polypropylene, etc., and 2 and 3 are both sides of the filter medium 1. The adhesive layer made of EVA resin, polyamide resin, polyester resin, etc. is shown. Note that, considering that the adhesive is solidified during the manufacturing process, a hot melt type adhesive such as polyester resin is most suitable. First, as shown in FIG. 2, adhesive is applied linearly to both side edges 4 of a sheet-shaped filter medium 1, respectively, to form adhesive layers 2 and 3. continue,
As shown in FIG. 1, a pair of triangular molds 5 having acute-angled tip portions 4 are arranged so that the tip portions 4 face each other and can freely move forward and backward through each other.
After supplying the filter medium 1 sheet with the adhesive layers 2 and 3 softened between the two pressing molds 5 while retracting as shown by the imaginary line in FIG. The sheet of filter medium 1 is sandwiched between both pressing molds 5, and the adhesive layers 2 and 3 are solidified at room temperature.The sheet of filter medium 1 is held in a state where the apex 6 is at an acute angle as shown in FIG. The adhesive layers 2 and 3 on the outer side of each zigzag vertex 6 are thicker, and the adhesive layers 2 and 3 on the inner side of each zigzag vertex 6 are thicker. A zigzag-shaped air filter medium 7 was created by forming the air filter medium thinly. When the filter medium 1 is bent by the triangular mold 5, the softened adhesive layers 2 and 3 are crushed by the tip 4 of the triangular mold 5, and the filter medium 1 is pressed and folded into a continuous mountain shape. is formed. Further, in this case, after applying the adhesive layers 2 and 3 to both sides of the filter medium 1, it is preferable to fold the filter medium 1 while the adhesive layers 2 and 3 are not solidified. A zigzag air filter medium 7 having a continuous mountain shape with an acute angle apex 6 obtained by the method described above.
Since the apex 6 is held at an acute angle by the solidified adhesive layers 2 and 3, the shape is a continuous chevron or sawtooth shape, and as shown in FIG. 4, it passes through the air filter. Since it crosses the airflow 8 (in the direction of the arrow) diagonally, the air that enters from one side 9 of the filter medium 1 passes through the filter medium 1 without being blocked by the filter medium 1, and from the other side 10 of the filter medium 1. Since it is easily discharged, the pressure loss of the filter medium 1 can be maintained low.

ことが出来る効果が有る。[Effects of the Invention] When the method of the present invention is used, the obtained filter medium is maintained in a continuous chevron shape or a sawtooth zigzag shape by the adhesive layer solidified on both sides of the filter medium, unlike the conventional method. Compared to filter media formed in parallel, it has the effect of less pressure loss, and has an adhesive layer applied to both sides of both sides. After bending the filter media with a triangular die, the adhesive layer is solidified. As a result, the folded filter media is formed into a continuous chevron shape by the solidified adhesive layer.
Alternatively, there is an effect that the zigzag shape of the saw blade can be easily and reliably maintained. In addition, the adhesive layer formed on both sides of the filter medium is formed at regular intervals on one side of the filter medium, with the adhesive layer being thick at the center and thinnest at both ends, and at the center of one side. If the adhesive layer is thinnest at the center of the other side corresponding to the part and thickest at both ends, the filter material can be bent at the center where the adhesive layer is thinnest. This has the advantage that the bending work can be done easily and reliably.
