摘要：
The present invention concerns a pleated filter media (12) extending in an axial direction (x), a transverse direction (y) that is perpendicular to the axial direction (x), and a lateral direction (z) that is perpendicular to the axial direction (x) and perpendicular to the transverse direction (y), the pleated filter media (12) comprising: a plurality of pleats (24) comprised of pleat segments (26) extending in the axial direction (x) between first and second axial ends (28a, 28b) and extending in the transverse direction (y) between first and second sets of pleat tips (30a, 30b) which are at least partially defined by first and second sets of bend lines (22a, 22b);
wherein axial flow channels (32) are defined between the pleat segments (26) in the lateral direction (z);
wherein the plurality of pleats (24) has a width in the transverse direction (y) that varies along the axial direction (x) at least along a portion of the plurality of pleats; and
wherein the portion of the plurality of pleats comprises at least a first linear portion (34a) extending at an angle to the axial direction (x) and a second linear portion (37b) extending at an angle to the axial direction (x).
wherein axial flow channels (32) are defined between the pleat segments (26) in the lateral direction (z);
wherein the plurality of pleats (24) has a width in the transverse direction (y) that varies along the axial direction (x) at least along a portion of the plurality of pleats; and
wherein the portion of the plurality of pleats comprises at least a first linear portion (34a) extending at an angle to the axial direction (x) and a second linear portion (37b) extending at an angle to the axial direction (x).
