Abstract: An extraction device of a platform for holding a blade fitted with an upstream flange, out of a turbomachine rotor disc, and extraction method using the device. The device includes a handle fitted with a radial annular shoulder extended by a threaded pin, a proximal ring and a distal ring having a tube extended by a radial collar and a sleeve. The proximal ring is arranged around the pin, the tapped distal ring being screwed onto the other end of the pin and the sleeve being arranged around the two rings between their respective collars. Screwing of the handle results in moving the distal ring towards the proximal ring, radial deformation of the distal part of the sleeve against the flared part of the cylindrical orifice of the flange and its being joined to the latter. It is possible to conjointly extract the platform and the device from the disc.

Abstract: A roll device as a spreader roll has a rotating hollow roll tube which at the ends thereof is rotatably mounted by means of bearing ends which are mounted in rotary bearings. The roll device has a tension element which runs so as to be eccentric to the central longitudinal axis of the roll tube through the roll tube and by internal tension toward the ends of the roll tube is impinged by a force with pressure. As a result, the roll tube is capable of being bent by way of an impingement of the tension element with a force, the deflection being transversely away from the longitudinal extent of said roll tube, if the tension element is tensioned in relation to the roll tube in an axial direction.
