Abstract

L'invention concerne une machine de duplication. La machine comprend un cylindre d'impression pourvu d'un premier dispositif de préhension servant à saisir le bord avant de la feuille et d'un second dispositif de préhension servant à saisir le bord arrière de la feuille, ce second dispositif étant agencé pour être inversé après la formation d'une première image sur la feuille en vue de la production d'une autre image sur son autre face, des moyens étant également prévus pour permettre un mouvement relatif du cylindre et du premier dispositif de préhension pour adapter la machine à des dimensions différentes de feuilles de copie. Application aux machines de duplication double-face.
