Abstract
A magazine for the automated changing of printing plates of a sheet-fed offset printing machine. The magazine includes a guiding apparatus which can be put into place on the plate cylinder for purposes of conveying used printing plates out of the plate cylinder and for feeding new printing plates to the cylinder. The guiding apparatus may be formed by a sheet-metal profile. Provision is made of further guiding surfaces and a holder so that the used printing plate may be locked by the holder. An operator then only need pull the plate a short distance out of the gripping region of a leading edge clamping rail. Stops are provided for a printing plate so that the new printing plate can be deposited on the stops. By virtue of putting the guiding apparatus into place, the new printing plate is shifted toward the plate cylinder and can be fed into the front clamping rail by the operator.
