Abstract:
A method for attaching an abradable piece support by crimping to the radially inner wall of a vane sector of a turbomachine, comprises deforming opposite rims of the radially inner wall on opposite free axial ends of the abradable piece support respectively, jointly, by means of two pressure blocks (40A, 40B) respectively, which are attached to each other and delimiting a space (42) between them intended to accommodate a median portion of the abradable piece support. A crimping attachment device (30) comprising such pressure blocks can in particular be operated by means of a conventional press, and can enable the method for attaching the abradable piece support to be automated.
