A method for producing contoured filter elements, wherein
- at least one filtering medium is applied to a strap-form backing material and detachably secured thereto, and
- the filtering medium is cut on the strap-form backing material to form the contoured filter elements, wherein the contoured filter elements can be detached for use from the strap-form backing material,
- wherein
- the strap-form backing material is provided,
- to form an outer contour of the filter elements the filtering medium is cut on the strap-form backing material, wherein the strap-form backing material remains uncut along the outer contour of the filter elements, and
- to form an inner contour of the filter elements at least one hole is cut into the filter elements, wherein the filter elements and the strap-form backing material are cut along the inner contour.
A filter element arrangement with a strap-form backing material, on which a plurality of contoured filter elements are detachably arranged, wherein the filter elements are formed by cutting a filtering medium applied to the strap-form backing material,
- wherein
- the filter elements are formed on the strap-form backing material by cutting with an outer contour, wherein the strap-form backing material remains uncut along the outer contour of the filter elements, and
- the filter elements have an inner contour with at least one hole, wherein the hole is cut into the filter elements and the strap-form backing material.
