    • A filter element (1) with a tubular folded bag (2) of folded filter material, which has a plurality of fold blades (3) adjacent each other in the longitudinal direction (10) of the folded bag (2) a closure cover (4) is attached at at least one axial end (7) of the folded bag (2). In order to provide a filter element which can be bent to any desired curved form while maintaining a high degree of filtration performance, and can be produced in a cost effective manner, the fold blades (3) of a folded bag (2) are provided with a combination of diagonal folds extending at an angle relative to each other such that the fold blades (3) in the longitudinal direction (10) of the folded bag extend back and forth and thereby form a three-dimensional crown structure (18). At least the outer margin of the closure cover (4) has a form corresponding to the crown structure (18) of the fold blades (3).
    • 一种具有折叠过滤材料的管状折叠袋(2)的过滤元件(1),其具有在折叠袋(2)的纵向方向(10)上彼此相邻的多个折叠叶片(3),封闭盖 4)安装在折叠袋(2)的至少一个轴向端(7)上。 为了提供可以弯曲成任何期望的弯曲形式同时保持高度的过滤性能并且可以以成本有效的方式制造的过滤元件,提供折叠袋(2)的折叠刀片(3) 其中对角折叠的组合相对于彼此以一定角度延伸,使得折叠袋的纵向方向(10)上的折叠叶片(3)前后延伸,从而形成三维冠状结构(18)。 封闭盖(4)的至少外边缘具有对应于折叠叶片(3)的冠部结构(18)的形式。
