    Abstract: 1,121,896. Filter element. GENERAL MOTORS Ltd. 7 July, 1967 [21 July, 1966; 25 Feb., 1967], Nos. 32844/66 and 9117/67. Headings B1D and BIT. [Also in Division B5] A filter element, for the air intake or lubricating oil circuit of an I.C. engine, comprises a flat pleated panel of resin-impregnated paper, pleat ends joined to form pockets which open on one face to which a sealing strip 37, of polyvinyl chloride, is secured. Peripheral grooves 30 (Figs. 10-12, not shown) are indented in the pleat crowns, and the flange 45 of a peripheral metal or cardboard frame around the element engages the mould 31 into which the element is pressed and forces the liquid plastics into grooves 30 and between pleats. Frame 41 may be made in one or two pieces and forms part of the finished element. The element is passed through an oven with the mould, to cure the plastics and resin. In Figs. 10-21, the grooves 30 are formed by vibratory wheels or hammers in the uncured paper. In Figs. 4-9, not shown, the grooves are made by pressing the element down on to a central member (20) of the two-part mould in which the sealing strip is formed. In Figs. 1-3. not shown, strips (4) of stiffer plastics are applied to the element before the moulding step, which adds further plastics thereto.

    Abstract: A filter element has a zigzag-folded filter medium. Filter medium sections joined by a fold edge define an intermediate fold space, respectively, with a fold base and fold peaks opposite the fold base. An elongate support section is arranged in the intermediate fold space on a filter medium surface of one of the filter medium sections. The support section extends perpendicular to the fold edges between fold base and fold peak. The support section has a height extension perpendicular to the filter medium surface that increases in longitudinal direction of the support section from fold base to fold peak. The support section has a free side facing away from the filter medium surface. The support section has a width extension parallel to the fold edges. The width extension decreases parallel to the filter medium surface and perpendicular to the longitudinal direction from fold peak to fold base.

    Abstract: An air filter may include a bellows made of an air-permeable filter medium, which is folded in a longitudinal direction to form a plurality of folds, for filtering air, and a supporting frame for supporting the bellows. The supporting frame may be a substantially closed comb-like ring having a plurality of supporting teeth. At least two supporting teeth adjacent in the longitudinal direction may fix at least two folds of the bellows also adjacent in the longitudinal direction to a predefined distance from each other. The comb-like ring may include two fold blades and two outer bands connecting the fold blades. The fold blades may be inserted in a transverse direction running transversely to the longitudinal direction into respective end folds of the bellows. The two outer bands may have the supporting teeth, including high supporting teeth and low supporting teeth.
