In a bladed rotor of the kind in which each blade has curved side surfaces and having fingers fitted in depressions of a shell and an opening of a core, the depressions of the shell and the opening of the core for receiving therein corresponding fingers of the blades are shaped and arranged so as to have, with respect to an elevational view of the rotor, longitudinal axes which coincide with straight lines extending radially through the center of the rotor, respectively. A die assembly for forming such depressions or openings in the shell or core is also provided. In such a die assembly, first and second die sections are adjustable in relative circumferential position for thereby adjusting the relative circumferential position relationship between the first and second groups of depressions or openings in the shell or core to be produced.
