Abstract

Parts used to make filters that have corrugated folds. And has a ring shape with a ridge fold And indentations alternately along the radial This part is placed on the first mold with a convex part. Protruding radial The first one is equal to the number of The ridges of the folds of the annular parts. And the number of the first circular grooves Equivalent to the number of indentations of the folds of the annular parts, the ridges of the folds are placed along the pattern above the first convex protrusion, and the indentations of the folds are directed down accordingly in the first groove. Thus, an annular part is pressed between the first mold and the second mold. The second mold has a protrusion. Come the second one along the curve And wear down in order In the first groove with the indentation of the fold that will be supported there and the second circular groove will be supported, respectively, with the protrusion. The first one, with the ridges of the crease to be inserted into it, the annular part is heated while being pressed between the first and second molds, which forms the shape of the filling. Annular filter and after that this annular filter is cooled.
