Abstract
The present invention relates to a device and a method for unloading a sheet medium from a vacuum drum which may be a vacuum drum of an imagesetter for example, or a vacuum drum of an input scanning machine. The unloading is facilitated by the stiffness of sheet medium. When the vacuum holding a sheet medium is released, the stiffness of the sheet medium causes the sheet to separate from the drum. A roll forces the sheet onto the drum and the motion of the drum forces the sheet medium onto a table which has been moved into proximity of the drum. The sheet travels onto a transport mechanism which eventually takes over the moving of the sheet medium without requiring synchronism between the drum rotational speed and the transport mechanism.
