Abstract

L'invention fournit un dispositif de fabrication de bande de fermeture dans lequel un axe de connexion côté levier (55a) connectant une extrémité d'une agrafe (55) et une troisième partie extrémité (52C) d'un levier (52), et un axe de connexion côté lame (55b) connectant l'autre extrémité de l'agrafe (55) et une seconde lame (41), sont disposés en rang sensiblement en ligne droite suivant la direction verticale de la seconde lame (41). Ainsi, il est possible de stabiliser le déplacement dans la direction verticale de la seconde lame (41), la position d'entrée d'une puissance d'entraînement vis-à-vis de la seconde lame (41) s'approchant du centre de gravité de cette dernière, et il est également possible d'augmenter les propriétés de suivi d'un rouleau vis-à-vis de la rotation d'un axe d'entraînement lors d'un entraînement à grande vitesse.
