A pair of supporting surfaces is formed between the spacer ring and the outer ring, and another pair of supporting surfaces formed between radial inner areas of the ring cutter and the perforated disks is designed as a wear active pair for blade adjustment. The spacer ring is engaged into an outer ring groove (8) of the ring cutter over guiding and coupling elements.</p> |
