Filter for Filtering Fluids

A filter for filtering a liquid or gaseous fluid comprising:

• a filter element (1) with a zigzag-folded filter medium (14;
• 106) including
• a raw side (105);
• and
• a clean side (104);
• a plurality of filter medium sections (120) joined to neighboring filter medium sections (120) along fold edges (F);
• a plurality of elongated adhesive sections (122) arranged on said filter medium (14;
• 106) and extending along at least two lines of adhesive (101), said at least two lines of adhesive (101) extending at least sectionwise at a slant or perpendicular to fold edges (F) of the filter medium;
• wherein on each line of said at least two lines of adhesive (101) at least one adhesive section (122) and least one interruption (107) of the adhesive are arranged;
• wherein said interruptions (107) of said adhesive of the different lines of adhesive (101), viewed in the direction of the fold edges (F), are displaced relative to each other such that by the interruptions (107) of the adhesive in said filter medium section (120) that extends between two neighboring fold edges (F) no passage (126) extending continuously parallel to the fold edges (F) is realized.
