Ce module d'alimentation comprend une pluralité de canaux d'alimentation (30, 40) dans lesquels se déplacent des éléments d'assemblage de différentes dimensions. Les canaux d'assemblage aboutissent à un emplacement de réception (50) adjacent à la tête d'insertion. Sur la base de l'accouplement entre l'emplacement de réception et les canaux d'alimentation, les éléments d'assemblage aux dimensionnements différents sont disposés individuellement dans l'emplacement de réception dans une orientation d'assemblage uniforme.
