  • Patent number: 7779499
    Abstract: A method for assembly of a stay includes a series of steps that include connecting in the vicinity of an anchoring zone, a new group of N reinforcements to a shuttle located within the sheath of a stay to be installed. The shuttle is driven towards another anchoring zone by means of driving and guiding means. When the shuttle has arrived substantially in the vicinity of the anchoring zone, and as long as entangling is detected between the driving and guiding means in a portion contained substantially between the shuttle and the first anchoring zone, the shuttle is rotated about its main axis in the opposite direction to the said entangling. The group of N reinforcements is then separated from the shuttle. Each reinforcement of the group is tensioned between the anchoring zones. The preceding steps are repeated until the installation of the reinforcements is completed.
