Le dispositif de liaison de renfort 1 est pourvu : d'un mécanisme d'alimentation 2 qui fournit le câble 301, qui est enroulé autour d'une bobine 24, au moyen de la rotation d'un moteur d'alimentation 21 ; d'un mécanisme de guidage 4 qui guide le câble 301, qui est fourni par le mécanisme d'alimentation 2, autour des renforts 201 ; d'un mécanisme de coupe 6 qui coupe le câble 301, qui est fourni par le mécanisme d'alimentation 2, à un emplacement prescrit ; d'un mécanisme de torsion 5 qui tord le câble 301 autour des renforts 201 ; d'un dispositif de commande 101. Le dispositif de commande 101 estime la longueur d'alimentation L× du câble 301 et commande l'alimentation du câble 301 sur la base de la longueur d'alimentation L× estimée.
