  • Method and apparatus for exchanging a roll of a printing press
    Patent number: 6142073
    Abstract: A side shift mechanism for a deck of a printing press enables a roll, for example, a plate roll and/or an anilox roll, to be shifted axially so that one end of the roll extends out of the frame of the press. The extended roll or a sleeve on the roll is thereby made accessible for easy exchange. After the roll or sleeve is exchanged, the roll is shifted back to its original position.
