    Abstract: A spacing and scoring tool for creating high density pleated filter media, and the media therefor is disclosed herein. A blade (14) having curvilinear portions (22, 22a) and linear portions (21, 21a) create an island pattern when scored into flat or corrugated media (16). The island are preferably located centrally upon the corrugation peaks (18) either at every peak or periodically. The resulting pattern when foled produces filter media with automatic pleat spacing and this structure can be used at very high pleat spacings beyond 10 pleats per inch. The blade (14) is solid on its contact face at the curvilinear portions for preventing island collapse when the media is folded.

    Abstract: A pleated media filter element is disclosed which includes pleat spacers which are an integral structural part of the pleated media. The construction of the pleat spacers is accomplished by scoring on the unfolded media a continuous line pattern upon the portion of the media which, when folded, forms a pleat tip of the element. When the scored media is folded into pleats the patterns each define areas on the respective pleat tips which are integral structural parts of the media itself. The configuration of the pattern causes a portion of the media at the pleat tip to project transversely relative to the respective pleat, serving thereby as an integral spacer to space the pleat apart from the pleats on either side thereof.

    Abstract: An air cleaner which includes a support (23) having a first concave conical surface (26) and compression means (50) extending along the axis of said surface away from the apex of said surface; an hollow inner filter (37) including a first end cap (41) with a rim (43) defining a first convex conical surface having the same apex angle as said first concave surface, and a second end cap (42) for axial engagement by said compression means; and a hollow, outer filter (32) including an end cap (57) with a resilient lip (61) extending inwardly to be sealingly received between said conical surfaces when said compression means engages said second end cap. The second end cap of the inner filter may have a second convex conical surface (47), and the outer filter may have a second end cap with a resilient lip extending to be sealingly engaged by the second convex conical surface.
