Abstract: In a method for producing a filter medium, at least one substrate layer of a nonwoven comprising cellulose fibers and/or synthetic polymer fibers is provided and a fiber layer of polymer fibers is deposited on the at least one substrate layer. Prior to depositing the fiber layer, a solvent is applied to the at least one substrate layer, wherein a material of the substrate layer and/or a material of the fiber layer is soluble in the solvent. A filter medium produced by the method has material-fused connections at crossing points of the polymer fibers and/or cellulose fibers of the substrate layer with the polymer fibers of the fiber layer.

Abstract: A filter insert piece has a filter element with first and second pleated sections each having parallel pleats. The first and second pleated sections each have an inflow side. A first flat outflow side of the first pleated section and a second flat outflow side of the second pleated section adjoin a common clean chamber of the filter element. A length of the pleats of the first and second pleated sections is such that a spacing of an outwardly positioned pleat end face of the pleats at the first or second inflow side, respectively, relative to the center axis increases or decreases monotonic from pleat to pleat. The respective end pleats of the first and of the second pleated sections have a different length extension measured from the outwardly positioned pleat end face of the first end pleats or the second end pleats relative to the center axis.

Abstract: A filter element for filtering liquids has a folded filter medium with outer fold edges and inner fold edges, wherein the inner and outer fold edges extend along a longitudinal axis of the filter element. A support body is provided with a first support body section and a second support body section, wherein the first support body section is facing the inner fold edges and hugs closely an envelope of the inner fold edges. An envelope of the outer fold edges and the second support body section hug closely at least sectionwise an outer circumferential surface of the filter element.

Abstract: A filter element for filtering a fluid is provided with a filter bellows made of a filter medium folded along fold edges in a zigzag shape to form folds, wherein the folds extend between oppositely positioned end face edges of the filter bellows. The filter bellows defines a raw side and a clean side of the filter element, wherein a fluid to be filtered flows from the raw side to the clean side. The filter medium has faces that are flowed through by the fluid to be filtered. The filter medium is provided at least on one of the faces that are flowed through with beads extending transversely to the fold edges. In a proper operating state of the filter bellows, the beads effect a flow of at least a portion of the fluid to be filtered in a direction perpendicular to the fold edges.

Abstract: A filter element is provided with a folded bellows that has a first pleated section with parallel arranged first pleats and a second pleated section with parallel arranged second pleats. The first pleats of the first pleated section are positioned at an angle relative to the second pleats of the second pleated section. The end face edges of the first pleats of the first pleated section adjoin a first clean chamber. The end face edges of the second pleats of the second pleated section adjoin a second clean chamber. The second clean chamber is delimited by a longitudinal side of an edge-side pleat of the first pleated section. The first and second clean chambers are connected to each other. A filter insert with such a filter element is provided.
