A brush ring for roller brush in a cleansing machine includes a ring (10C) having a U-shaped cross section. Openings (11) with upstanding walls (12) are made in the ring and the bent-over ends of the hairpin-like bristle bundles (16) are thrust into the openings. The bent-over bristles are free inwards of the inside of the ring, and a locking wire (15) is taken through these ends to form a locking wire ring on the inside of the annular bar for reliably retaining the bristle bundles in the openings when the ring is rotated during operation. |
