The ring (1) has a set of guide vanes (12) arranged among fastening rings (10, 11, 11') and fixed in respective angular position, where the rings are arranged coaxially. The guide vanes include a positioning aid on an end face partially corresponding to an outer contour of the end face. The guide vanes are fixed with regard to angular position by the arrangement of the positioning aid in an opening (14) corresponding to the shape of the positioning aid in the second fastening ring. An independent claim is also included for a method for manufacturing a nozzle ring. |
