Abstract
A tool for holding a blade blank (1) comprises a frame (13) in which a control system using clamping jaws (18, 19) and lifters (30, 34, 35) grips the blade and holds it in position vertically on two supporting faces (22, 23), while the blade has been laid on three lateral faces (41, 42, 43). The blade is thus simultaneously held in a precise position and gripped sufficiently tightly, with a single control main mechanism. The mounting of the blade is thus greatly simplified and it may be subjected without further precaution to a manufacturing operation such as welding by friction to a rotor disk.
