Problems solved by technology

[0009] The combination of non-woven media can also be arranged in the form of two thin strips placed on the lateral ends of the pleats of the filter plate, but this solution cannot simply ensure a seal over the entire outer contour of the filter element continuity

Embodiment Construction

[0046] Figures 1 to 6 The manufacturing method of the filter element 1 is shown. like figure 1 As shown, the method comprises a first step a) consisting in providing a filter panel 2 consisting of a filter medium layer, eg of polyester elastic non-woven material. The synthetic material comprises in particular fibers whose core is of polyester material and whose sheath is of copolyester material, the sheath having a much lower melting point than the core. This layer is pleat folded to present a set of parallel pleats extending transversely between the first and second longitudinal edges 4,5. Usually, this layer is preformed by mooring, by gluing or welding (joining) the longitudinal ends of the folds 3 two by two, shaped with two tailless screws to form the first and second longitudinal ends 4 , 5 . The layer is then kept flat by providing a longitudinal connection, such as an adhesive strip or thin strip on top of the folds 3 (in the figure 1 The face shown is opposite to...

Abstract

It comprises the steps consisting of: a) providing a filtering panel (2) having a plurality of parallel folds (3) extending between a first planar longitudinal edge and a second planar longitudinal edge (5), the filtering panel (2) comprising, at the longitudinal ends of same, a first end fold (6) and a second end fold (7), b) raising and holding the first end fold (6) and the second end fold (7) in a plane substantially parallel to the planes of the longitudinal edges (5), and c) fixing a first sealing strip (8) on the first longitudinal edge, on a first portion (9) of the first end fold (6) and on a first portion (11) of the second end fold (7), and d) fixing a second sealing strip (12) to the second longitudinal edge (5), on a second portion (13) of the first end fold (6) and on a second portion (14) of the second end fold (7). The invention also concerns a filtering element (1) that can be obtained by means of said method of production.

Description

technical field [0001] The invention relates to a method for producing a filter element, which is an air filter (engine or cabin) for a motor vehicle. [0002] The invention also relates to a filter element, which is an air filter for a motor vehicle obtainable by the filtering method. Background technique [0003] Commercially available filter elements are mostly made of paper or synthetic material, pleated to increase the filter area achieved. These filter elements are provided with a joint that ensures a tight seal between the filter element and its receptacle (such as a cover-closed slot for an engine air filter), thus ensuring an undisturbed air-tightness commonly referred to as the "dirty air side". Strict separation between the volume of filtered air and the volume containing filtered air, commonly referred to as the "clean air side". [0004] The binders used can be of different compositions, such as thermoplastic resin or polyurethane cast over the filter element ...
