Abstract

The invention relates to a filter element for filtering liquids having a filter belt (1), made of a filtering nonwoven fabric, which can be folded in a zigzag. The nonwoven fabric contains metal fibers, glass fibers and/or polyester fibers. The filter belt (1) folded in a zigzag is made from pre-embossed plates of a filtering nonwoven fabric, or from a rolled strip of a filtering nonwoven fabric. The individual surfaces of the zigzag shape can be formed by pre-embossing (3, 4, 5,6 ), preferably for star folding.
