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.
