Publication number: 20100236206Abstract: In a method for manufacturing a filter element of layers of a flat material and a corrugated material resting against one another, wherein the corrugated material has peaks and valleys, an adhesive is applied onto the flat material or the peaks of the corrugated material in a direction substantially parallel to the peaks of the corrugated material to be glued onto the flat material. The peaks of the corrugated material are then glued onto the flat material. A filter element is thus produced of layers of a flat material and a corrugated material resting against one another, wherein the corrugated material has peaks and valleys, wherein the peaks of the corrugated material are glued onto the flat material by adhesive strips that extend substantially parallel to the peaks.Type: ApplicationFiled: March 19, 2010Publication date: September 23, 2010Applicant: MANN+HUMMEL GMBHInventors: Susanne Klupski, Jochen Linhart, Josef Rohrmeier
