Abstract
Disclosed is a device for transporting printing plates, having one coated and one uncoated surface, stacked in a holder to an exposure and developing station and for positioning them, comprising a holder for holding a plurality of printing plates stacked in alternating relationship with a plurality of separating sheets and a device for selectively positioning the holder substantially perpendicularly to the direction of transport of the printing plates so that the uncoated surface of each printing plate faces toward the direction of transport. A suction device engages the uncoated side of the first printing plate from the stack in the holder, and a device, movable horizontally in the direction of transport, is provided for transporting the suction device between a first position adjacent to the holder and a second position displaced from the first position in the direction of transport, to withdraw the engaged printing plate from the stack. A selectively engageable gripping device for the lower edge of the withdrawn printing plate is positioned beneath the second position of the transporting means. At least one nozzle is positioned adjacent to the holder and is pointing generally in…
