Dans ce dispositif de traitement de feuilles, une paire d'éléments de guidage de forme cylindrique (34a, 34b), entraînés en rotation au niveau du point faisant avancer les feuilles, sont opposés et espacés au niveau de l'intervalle dans lequel se déplacent les feuilles, une pluralité de parties saillantes (342) se dressent verticalement, à un intervalle prédéterminé, sur la périphérie de chacune des surfaces opposées des éléments de guidage circulaires (34a, 34b). Lorsqu'une feuille à l'avance, l'extrémité avant de la feuille est guidée entre les parties saillantes adjacentes (342) par les éléments de guidage circulaires (34a, 34b). Lors du passage de la feuille, la partie saillante (342) est conçue pour reculer depuis la surface inférieure de la feuille, et la face arrière de la feuille est retenue par une partie saillante (342) à la position suivante.
