A method for producing a filter element provided with a sealing part in which the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, and a compensation space connected to the casting chamber for the expansion of the sealing material.

Method for producing a filter element provided with a sealing part

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.

Method for producing filter bellows

For a method for producing a filter element provided with a sealing part, wherein the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, a compensation space connected to the casting chamber is provided for the expansion of the sealing material.

An air filter insert including at least one filter element () and a seal () extending along outer edges of one side of the filter insert () and via which the filter insert is sealingly seated against housing sections () of a surrounding filter housing. The filter insert () 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 () may be at least partially covered on the inflow and/or discharge side by a semi-permeable component (), which at least partially equalizes the pressure distribution in the air stream. The filter element also may be supported in the filter housing via a circumferential seal () which is disposed on the outer periphery of the filter insert and received in a seat () of a lower housing section (), and a sealing pressure is applied by an upper housing section (), so that the overall height of the filter insert is decreased and the surface of the seal () is substantially co-planar with the surface of the filter insert ().
