ABSTRACT:
A printing plate clamping assembly is situated within a housing carried in a groove at the periphery of a plate cylinder. An adjusting shaft is supported for both rotation and translation by a plurality of spaced roller rings. A bearing support is carried by the adjusting shaft and receives a first end of a connecting link. A second end of this connecting link is received in a first end of a first lever arm of a clamping bar which has a clamping flap at a free end of a second lever arm. Movement of adjusting shaft in both a rotational and transitional manner effects proper printing plate end clamping over a wide range of plate thicknesses.
