摘要: A filter element and method for making it include the steps of providing a pleated paper filtering media (88) batt-like (90) containing thermoplastic fibers which is slightly larger than media. ring-shaped die (94) used in press (82) to apply heat pressure edges (92) while accommodating rest aperture (96) (94). Accordingly, stiffened wall (110) provided circumscribes (88). The attached stiffened, fluid-impermeable provide seal therebetween. perimetrically-extending flange gasket (108) simultaneously formed around edge (90), so that latter can be sealingly engaged an air cleaner housing (118).
