ABSTRACT:
A plate exchange apparatus for a printing press includes a plate holding unit and positioning members. The plate holding unit is supported on frames such that a distal end thereof is movable between an operative position and a retracted position. At the operative position, the distal end of the plate holding unit comes close to plate lockup devices disposed in a gap of a plate cylinder. The distal end of the plate holding unit is retracted from the operative position to the storing position. The positioning members are provided at the distal end of the plate holding unit to be brought into contact with a member on the plate cylinder when the plate holding unit is located at the operative position.
