Beschreibung
Zusammenfassung:	An apparatus for processing a lithographic printing plate material comprising a development unit (5) including a development cavity (6), said cavity comprising a bottom plate (10), a cover plate (7) and sidewalls (21,22) which together define a volume which is closed with the exception of an entry aperture (8) which allows a plate material to enter the cavity and an exit aperture (9) which allows a plate material to leave the cavity; characterised in that the cover plate (7) is provided with at least one protruding element at the side facing the development unit. L'invention concerne un appareil pour traiter un matériau de plaque d'impression lithographique comprenant une unité de développement (5) comportant une cavité de développement (6), ladite cavité comprenant une plaque inférieure (10), une plaque de couverture (7), et des parois latérales (21, 22) qui définissent ensemble un volume qui est fermé à l'exception d'une ouverture d'entrée (8) qui permet à un matériau de plaque d'entrer dans la cavité et d'une ouverture de sortie (9) qui permet à un matériau de plaque de quitter la cavité ; caractérisé par le fait que la plaque de couverture (7) comprend au moins un élément en saillie sur le côté faisant face à l'unité de développement.
