  • Master loading and unloading apparatus for a lithographic printing machine
    Patent number: 4008660
    Abstract: An apparatus is disclosed for loading a master onto and unloading the master from the rotating master cylinder in a lithographic printing machine at substantially the same angular position of cylinder rotation. The apparatus includes external grippers for gripping a master edge and moving it into the proximity of the cylinder through a master delivery path. Internal grippers for gripping and later releasing the master edge in the proximity of the cylinder are mounted in the cylinder and are extendable beyond the cylinder surface during a first angular sector of cylinder rotation to describe a master receiving path that intersects the master delivery path in a loading merger region. The internal grippers are also extendable beyond the cylinder surface in a second angular sector of cylinder rotation to describe a master release path.
