Abstract

L'invention concerne un dispositif destiné à séparer un flux d'objets plats transportés (8) dans lequel le flux peut être dirigé au choix sur un premier chemin de transport (1) ou sur un deuxième chemin de transport (2) par un élément de séparation (3). À cet effet, l'élément de séparation (3) peut être déplacé par rapport au flux des objets plats (8) et laisse le flux sur le premier chemin de transport (1) dans une première position et dirige le flux sur le deuxième chemin de transport (2) dans une deuxième position. Lors de la transition de l'élément de séparation (3) de la première position dans la deuxième position, l'élément de séparation (3) est déplacé dans le flux avec une pointe de séparation (32) par un mouvement associé au flux et lors du retour de l'élément de séparation (3) de la deuxième position dans la première position, l'élément de séparation (3) est également sorti du flux par un mouvement associé au flux.
