Abstract

L'invention concerne un dispositif de fabrication d'une étiquette de sécurité, comprenant : un cliché et une fraise qui forment entre eux une fente de fraisage et qui coopèrent entre eux pour réaliser un fraisage sur un article souple comportant un support et une couche de métal, au moins une structure d'antenne et un élément de pont dans la couche de métal, tandis que l'article est transporté dans une direction de transport à travers la fente de fraisage, la structure d'antenne comportant une première et une deuxième extrémité d'antenne. Le dispositif comprend en outre une unité de pliage/contact qui est agencée dans la direction de transport de l'article en aval de la fente de fraisage et qui sert à plier l'article transporté à travers la fente de fraisage de sorte que l'élément de pont chevauche une ligne entre la première et la deuxième extrémité d'antenne.
