Un trou rond (34a) est formé dans la roue menante (41) et un long trou (33) est formé dans le rouleau d'estampage (31). Un premier arbre (35a) d'une tige excentrique (35) est inséré dans le trou rond (34a) et un deuxième arbre (35b) de la tige excentrique est inséré dans le long trou (33). En faisant tourner la tige excentrique (35) à l'intérieur du trou rond (34a), les phases de la paire de rouleaux d'estampage (31, 32) dans la direction circonférentielle sont ajustées, ce qui facilite l'ajustement du glissement dans la direction circonférentielle entre la paire de rouleaux d'estampage et les distances entre les arbres et rend possible la formation de têtes d'engagement avec d'excellentes propriétés d'engagement.
