ABSTRACT:
A cylinder of a rotary offset printing machine is provided with a gapless lock-up means for an offset plate or metal backed offset blanket by setting into the cylinder a fixed jaw and a movable jaw that have facing undercut surfaces defining a recess within which the end tabs of an offset plate or metal backed blanket are received. As the jaws are closed the end tabs are clamped firmly between the jaws. A slight tendency of the end tabs to bulge at the outer margins of the jaws is overcome by an anti-creep means which is distorted between the end tabs as the jaws close so as to produce an inward force component on the end tabs.
