エレメト。 Folding lines 2 for forming mountain folds in the longitudinal direction of one filter paper 1
are formed in parallel at regular intervals, and intersect on the creases 2 for forming the mountain pleats to form creases 3 for forming the valley pleats forming a rhombus and extending in an oblique direction. The filter paper is bent using fold lines 2 and 3 as folds to form mountain folds 2a and valley folds 3a, respectively, and folded folds are formed to form a rhombus between the intersection points in the transverse direction of the fold lines 3 for forming valley pleats. A folding line 5 for forming a folding pleat is formed in the center of the folding line 4 and the folding line 4 for forming a folding pleat.
are folded alternately in the longitudinal direction to form folded corner portions 4a, and folded creases 5 for forming folded pleats are formed.
A folded filter element in which a folded folded portion 5a is formed as a fold, and the entire folded folded structure is formed into a wavy folded structure.
