Abstract

L'invention concerne un procédé de réalisation d'éléments d'accès faciles à ouvrir et un appareil pour sa mise en oeuvre. Pour mieux assurer l'intégrite de l'élément d'accès, en particulier dans une tôle tenace telle que l'acier, ledit procédé consiste, après formage dudit élément d'accès et incision longitudinale jusqu'à fracture de ce dernier, à réaliser une bande estampable du métal le long d'un bord de la ligne de fracture et recouvrant ledit bord et à estamper et déployer la bande radialement pour qu'elle recouvre plus intimement la ligne de fracture afin de la fermer hermétiquement couvercles de boîtes Application à la fabrication en série de couvercles de boîtes faciles à ouvrir.
