Abstract

The invention relates to a fitting device for producing the arrangement for locking a sealing element, arranged at the front end on a rotor of a turbine, against a displacement in the circumferential direction, the sealing element locking moving blades arranged on the rotor against an axial displacement. Furthermore, the invention comprises a method of producing the arrangement for locking a sealing element, arranged at the front end on a rotor of a turbine, against a displacement in the circumferential direction. The quality of the fitting can be further increased by means of a modular, mobile fitting device which secures the sealing element for the duration of the bending operation.
