ABSTRACT:
Disk shaped print masters are guided by means of a carrousel in step wise rotation through a series of processing stations. Support elements for the print masters are arranged on the periphery of the carrousel. A displaceable radially locking pin is associated with each support element in the carrousel in its outer normal position, the pin engages a peripheral notch of the master disk (D) located on the support element (TR), thereby defining its rotational position. The locking pins may be displaced radially inward in selected processing stations by common mechanical means thereby disengaging them from the master disks. The device makes it possible in a mechanically simple and inexpensive manner to immobilize the print masters during their transportation and to release them in certain processing stations.
