  • Patent number: 10556200
    Abstract: In a method for producing two or more filter bellows, a bellows with a filter medium with fold edges is provided, wherein the filter medium is running in a running direction. A cutting path is carried out in the bellows with the filter medium in a direction that, at least in some regions, is transverse relative to the fold edges such that the filter bellows are produced in parallel and the cutting path creates end edge faces and/or side faces of the filter bellows and the filter bellows are embodied lying adjacent to each other and symmetrical or point-symmetrical relative to each other in the running direction and/or transverse to the running direction. A filter element with such a filter bellows and a filter system with such a filter element and filter bellows arranged in a filter housing are provided.

  • Publication number: 20180361300
    Abstract: A filter bellows with zigzag-folded filter medium has first and second fold edges extending between opposite end edge faces of the filter medium. The filter bellows has opposite end faces with an end fold. The filter bellows in use has a raw fluid-side surface and a clean fluid-side surface. First fold edges are positioned at the raw fluid-side surface and second fold edges are positioned at the clean fluid-side surface. The filter bellows has a passage extending between raw fluid-side surface and clean fluid-side surface. The passage has a first opening at the raw fluid-side surface provided with a first cross section and a second opening at the clean fluid-side surface provided with a second cross section. When projecting the first and second openings onto each other, one cross section, at least with sections thereof, is arranged outside of the other cross section.

  • Publication number: 20180168404
    Abstract: A filter medium is embossed to form embossments and the filter medium is then cut at least in some sections by a cutting device such as a water jet, a laser beam, an ultrasonic cutting device, or a cutter, by moving a point of impact of the cutting device relative to the filter medium to produce a cutting line. After cutting, the filter medium is folded. Alternatively, the filter medium is folded to folds and then at least some of the folds are pulled apart at least partially. In a region of the folds which have been pulled apart, the filter medium is cut at least in some sections thereof by the cutting device by moving a point of impact of the cutting device relative to the filter medium to produce a cutting line. After cutting, the folds are reset.

  • Patent number: 7637976
    Abstract: An air filter insert including at least one filter element (2; 4; 11) and a seal (3; 7) extending along outer edges of one side of the filter insert (2; 4; 11) and via which the filter insert is sealingly seated against housing sections (5, 6) of a surrounding filter housing. The filter insert (2; 4; 11) is configured such that the air can easily flow into or out of the structural space on the one side of the filter element with a minimum pressure drop. The filter insert (11) may be at least partially covered on the inflow and/or discharge side by a semi-permeable component (12), which at least partially equalizes the pressure distribution in the air stream.
