Patent ID: 7779499

Claim:
Method for the assembly of a stay comprising an inclined sheath and a bundle of substantially parallel tensioned reinforcements housed in the sheath and individually anchored in a first and a second anchoring zone, the reinforcements being installed in groups of N reinforcements, N being a number equal to or greater than 1, in which the sheath and some of the reinforcements are installed, comprising the steps of: /a/ connecting, in the vicinity of the one of said first and second anchoring zones, a group of N reinforcements to a shuttle locatable inside the sheath; /b/ driving the shuttle towards the other of said first and second anchoring zones by means of driving and guiding means; /c 1 / when the shuttle has arrived substantially in the vicinity of the other anchoring zone, detecting entanglement between the driving and guiding means in a portion contained substantially between the shuttle and the other anchoring zone; /c 2 / while the shuttle is substantially in the vicinity of the other anchoring zone, rotating the shuttle about its main axis in the opposite direction to the said entanglement in response to said detecting; /d/ separating the group of N reinforcements from the shuttle; and /e/ tensioning each reinforcement of the group between the anchoring zones.
