Abstract

L'invention concerne un dispositif guide-feuilles pour un cylindre de transfert (1) dont le rôle est de guider une feuille saisie sur le côté d'un cylindre de transfert et entraînée par celui-ci du fait de la rotation du cylindre de transfert. L'objectif de l'invention est de créer des solutions grâce auxquelles il est possible de réaliser en peu de temps une modification de la configuration d'un dispositif guide-feuilles associé à un cylindre de transfert ou au moins son nettoyage. Selon l'invention, cet objectif est atteint par un dispositif guide-feuilles pour un cylindre de transfert avec un caisson de soufflage (2) et un déflecteur (3) qui recouvre le caisson de soufflage dans la direction du cylindre de transfert et forme une surface (F) de guidage des feuilles tournée vers le trajet de passage des feuilles. Le déflecteur peut être retiré du caisson de soufflage et le caisson de soufflage est intégré dans la presse d'impression de manière à pouvoir pivoter autour d'un axe de basculement (K) qui s'étend parallèlement à l'axe de rotation (x) du cylindre de transfert. Au niveau de chacune des deux zones latérales du caisson de soufflage, une glissière d'insertion (4) est formée, dans laquelle la partie de bordure latérale du déflecteur peut coulisser.
