Abstract: The assembly apparatus comprises a frame for supporting the straps of the first set of straps in mutually parallel positions, clamping and engagement for clamping on each of the straps of a second set of straps in succession and for engaging them with the straps of the first set in position in the support frame, and at least one comb that is movable between a disengaged position and a position in which it engages each of the straps of the first set.

Abstract: The assembly apparatus (14) comprises a frame (16) for supporting the straps (2) of the first set of straps in mutually parallel positions, clamping and engagement means (30) for clamping on each of the straps (3) of a second set of straps in succession and for engaging them with the straps (2) of the first set in position in the support frame (16), and at least one comb (29) that is movable between a disengaged position and a position in which it engages each of the straps (2) of the first set. The support frame is secured to a fixed structure (15), the clamping and engagement means (30) and the comb (29) being mounted to move in respective planes perpendicular to the straps (2) of the first set on a carriage (22) which is itself mounted to move in a direction parallel to the longitudinal direction of the straps (2) of the first set, and the clamping means (30) comprise two jaws (30a, 30b) having studs for retracting the springs of the strap (3) of the second set of straps by pressing against them.

Abstract: In a turbomachine in which the stator includes at least one stage of pivole blades and a ring which is movable axially to operate the levers which rotate the blades, the ring is moved by varying the pressure of gas which is contained in sealed chambers and which exerts a force between the movable ring and another fixed ring. This arrangement enables a better distribution of the forces to be achieved than purely mechanical movement control systems.
