ABSTRACT:
The positioning device is used in an exposing and developing apparatus for printing forms comprising an exposure table having an exposure position with a forward side, a rear side, and two lateral sides, and a transport device for transporting printing forms onto the exposure table. The positioning device comprises a mechanism for positioning individual printing forms in the transverse direction comprising stop pins mounted on the exposure table on one side of the exposure position, a pressure member mounted opposite the stop members and a pressure mechanism for moving the pressure member laterally of the exposure position toward the stop pins for forcing a printing form laterally against the stop pins. The device also includes a mechanism for longitudinally positioning individual printing forms comprising a stop mounted on the exposure table on the exposure position front side and a slide mounted for movement forward of the exposure position for forcing a printing form toward the forward stop, the transverse positioning mechanism and the longitudinal positioning mechanism are actuated simultaneously.
