Abstract

L'invention concerne une chaîne dentée comprenant une pluralité de maillons dentés (1) qui disposent respectivement d'au moins deux ouvertures (2a, 2b) espacées l'une de l'autre par lesquelles un système de boulon (3) en forme de tige, adapté en longueur à la largeur de la chaîne, est introduit pour relier les différents maillons dentés (1), le système de boulon (3) se terminant du côté frontal à l'intérieur de la région d'un chanfrein (5) de l'ouverture (2a; 2b) d'un maillon extérieur (4) pour y être riveté sans dépasser, le système de boulon riveté (3) étant relié par liaison de matière à la paroi de l'ouverture (2a, 2b) dans la région périphérique de la tête de rivet (6) sur le bord extérieur du chanfrein (5).
