Abstract (en)
[origin: EP1980366A1] The device (1) has a blade root (3), blade platform (4) and blade sheet (5) with a blasting cubicle (6), which includes an insert opening (8). A jet unit delivers an accelerated shot into the blasting cubicle, and a holder (7) for the turbine blade. A seal (11) is provided for sealing a gap (10) between the holder and blade platform within a region of the insert opening, and preventing withdrawl of dust, developed during radiation from the blasting cubicle. The seal seals the gap from the cubicle interior.
