Abstract

Flexible printing plates are produced by a printing plate producing machine and then transferred at a transfer station to a series of grippers mounted on an endless roller chain and which can be swiveled and opened by cooperating connecting links to engage the printing plates. The printing plates are then brought to an unloading station where the grippers are pneumatically opened in a receiving head and the printing plates are dropped into a plate stacker for guiding the printing plates into a series of bins.
