    摘要: An approach to providing folded flute ends in z-filter media is provided. The approach generally involves providing an initial deformation in a flute or corrugation to form at least one foldable tip and then folding the at least one foldable tip over. Techniques for both supported deformation and unsupported deformation are provided. Preferred corrugated media having fold arrangements, filter constructions having such fold arrangements, and filter system using such filter constructions are provided.
