摘要: A pleating method comprises disposing a filter material on a support surface and compressing a portion of the filter material between first and second pleating surfaces to form a pleat, where at least one of the pleating surfaces is curved or extends at an acute angle with respect to a support surface.

摘要: A filter includes a cylindrical filter element having a longitudinal axis, first and second end surfaces, and a plurality of longitudinal pleats. Each of the pleats has a pair of legs with first and second surfaces. The pleats are in a laid-over state in which the first surface of each leg is in intimate contact with the first surface of an adjoining leg and the second surface of each leg is in intimate contact with the second surface of an adjoining leg over substantially the entire height of each leg and over a continuous region extending for at least approximately 50% of the axial length of the filter element. An impervious end cap is connected to the first end surface of the filter element.
