<p>The method involves providing a layer of smooth material (1) and another layer of corrugated material (2), where the corrugated material has corrugation crests and corrugation troughs. The corrugation crests of the corrugated material is adhesively bonded at the smooth material, and an adhesive (5) is applied on the smooth material parallel to the corrugation crests to be bonded using a roller (9) or on the corrugation crests. The smooth material and/or the corrugated material are made of filter flies material i.e. cellulose material, and a filter element is soaked in ceramic fluid. An independent claim is also included for a filter element comprising a layer of smooth material and another layer of corrugated material.</p> |
