Abstract

Agrafeuse automatique dans laquelle des bandes d'agrafes (11) sont chargées depuis un rouleau (16) d'agrafes dans la partie arrière de la machine le long d'un guide (12). Un système d'entraînement (13) fait avancer par intermittence la bande d'agrafes vers un élément de commande (60). Ce dernier entraîne la partie supérieure de la première agrafe de la bande à forcer le passage de celle-ci dans une pièce.
