Abstract
In a method for manufacturing a ceramic filter element for an exhaust gas filter for internal combustion engines, a combustible non-ceramic support web provided with flow channel is impregnated with ceramic slurry. Subsequently, the support web, formed in a desired geometric shape, is fired until the support web is combusted and a rigid filter body is produced. Before impregnating the support web, a combustible sealing bead is applied such onto the support web that the flow channels are closed alternatingly by the sealing bead.
