A method for forming a filter mat (1) suitable for filter fluids includes forming at least one web section (39) of a mat web (9) and at least one welding line (13, 15, 41) that seals the layers of at least one web section (39) of the mat web (9) to each other. Subsequently, at least one cut (19, 37) is carried out along the at least one welding line (13, 15, 41) such that the at least one web section (39) is cut forming at least one sealed edge region (43). |
