Abstract (en)
[origin: EP2447474A1] The arrangement has blade-sided bases adapted for holding blades (3) in an accommodating channel (2) that is formed in a wall of fluid flow path of a turbo machine. Intermediate fillers (4) separating the bases are accommodated in a form-fit manner and fixed in a force-fit manner. The fillers fill the channel under formation of a constraining contour-free gas-flow side surface between the bases. Laterally perpendicular threaded bores for channel bases are provided in the fillers and are provided with screws (5) that are tightened by its adjustment against the channel bases.
