Claims (1)
して中空筒状の本体を形成したフイルタエレメン
トにおいて、前記帯状濾紙1は、その展開状態に
おいて、周方向に水平に平行して複数のひだ形成
用谷折り筋2を等間隔に形成するとともに、該谷
折り筋2上にて一定間隔で交叉する斜方向のひだ
形成用山折り筋3を平行して複数形成し、これら
ひだ形成用折り筋2及び3を折目として前記筒状
本体を上下方向に屈曲してひだを形成させて両折
筋の交点4を角部とする多角の中空筒状体を構成
したことを特徴とするフイルタエレメント。 In a filter element in which a hollow cylindrical main body is formed by bending a sheet of band-shaped filter paper into pleats, the band-shaped filter paper 1 has a plurality of pleats formed horizontally in parallel to the circumferential direction in its unfolded state. Valley creases 2 are formed at equal intervals, and a plurality of diagonal pleat forming mountain creases 3 are formed in parallel and intersect with each other at regular intervals on the valley creases 2. A filter element characterized in that the cylindrical body is bent in the vertical direction using fold lines 2 and 3 to form pleats, thereby forming a polygonal hollow cylindrical body whose corners are intersection points 4 of both fold lines. .
