Segment of a circle for holding a filter segment

摘要

The circular segment has two opposing lateral sections, where each lateral section includes an inner surface for guiding a filter segment, and a corresponding outer surface (9) executed as an adjacent surface for the corresponding outer surface of another circular segment. Detachable individual elements (6) are linked to each other, where two of the individual elements have the same type of structure. The individual elements have a common connecting plane that is perpendicular to the outer surface, where the individual elements are arranged mirror-symmetrically.
