The aim of the invention is to create a device which enables rational provision of printing plates of various types and sizes for the most different types of printing plate scanners, in spite of having means which are as few as constructively possible. To this end, a device is provided for loading and/or unloading printing plates into and out of a scanner, especially a drum scanner, said device comprising suction means which are used to receive printing plates, especially thermoprinting plates, and are provided with at least one suction plate and at least two suction heads connected to a vacuum system. The suction plate is embodied as a segment of a cylinder and can be deformed at least in terms of the surface form thereof.
L'invention vise à créer un dispositif qui, tout en étant de conception la plus simple possible, met à disposition de façon rationnelle des plaques d'impression de type et de dimension les plus divers pour des types d'appareil d'exposition les plus variés. A cet effet, sur un dispositif servant à charger et/ou décharger des plaques d'impression sur un appareil d'exposition, notamment un appareil d'exposition à tambour, un moyen d'aspiration pour recevoir des plaques d'impression, notamment des plaques de thermo-impression, comprend au moins une plaque d'aspiration et au moins deux têtes aspirantes reliées à un système de dépression. Selon l'invention, la plaque d'aspiration a la forme d'un segment cylindrique et sa forme peut être modifiée, du moins son plan.
