Abstract
A method for automatically feeding a printing plate in proper registry to a plate cylinder in a printing machine is disclosed. Pursuant to the disclosed method, a printing plate is advanced by a plate conveyor towards a clamping rail on the plate cylinder. After the leading edge is inserted into the clamping rail, the in-register condition of the leading edge of the printing plate is independently sensed at two sensing sites. If the leading edge of the printing plate is in register at only one site, the printing plate is released from the plate conveyor for a period of time to permit the printing plate to align itself. The printing plate is then held again by the plate conveyor and the advancement of the plate is resumed. This process is repeated until the independent sensors both indicate that registry has been achieved.
