Abstract

Cet appareil de conversion de pas d'étiquette RFID comprend un premier guide de repli pour replier une première feuille de support, un second guide de repli pour replier une seconde feuille de support de telle sorte que l'extrémité repliée de la seconde feuille de support fait face à l'extrémité repliée de la seconde feuille de support, et un dispositif de récupération pour récupérer une seconde étiquette RFID à partir de la première feuille de support. Le premier guide de repli et le second guide de repli se font face l'un par rapport à l'autre à travers un espace qui est plus petit que la taille de direction d'agencement d'étiquettes RFID. La vitesse d'alimentation de la seconde feuille de support est réglée de telle sorte que la distance entre des première et troisième étiquettes RFID de la seconde feuille de support est inférieure à la distance entre des première et troisième étiquettes RFID de la première feuille de support.
