Abstract
In accordance with the invention, a plate-clamping mechanism is provided for clamping and locking flexible printing plates on a printing cylinder wherein a clamping jaw fitted into a cylinder cavity has a leading edge for clamping one end of printing plate which is (1) non-parallel to the cylinder's axis of rotation and (2) coincident with the periphery of the cylinder when the clamping jaw is in its opened or closed position. In addition, the clamping jaw's axis of rotation is parallel to the jaw's leading edge. Such a clamping jaw eliminates any void between the printing plate and the cylinder surface which might otherwise exist after the plate is tensioned and clamped: such a void is common in printing cylinders with clamping jaws having leading edges non-parallel to the cylinder's axis of rotation.
