ABSTRACT:
A mechanism for securing and tightening a blanket on a cylinder of a printing press, particularly an offset press, which includes a rockable clamping shaft mounted in the groove on the cylinder together with a movable jaw member on the shaft, the jaw member being rockable between open and closed positions about an axis which extends longitudinally adjacent the surface of the shaft, so that when the shaft is in a reference position and the jaw member is open, an entryway is created which faces chordwise of the cylinder. The jaw member is held open against a force of bias by a stop surface on the cylinder for reception of a reinforcing bar at the end of the blanket, but when the shaft is manually rotated away from its reference position the jaw is automatically closed to capture the bar following which the bar is swung in a direction to tighten the blanket. A similar mechanism, in mirror image, is provided in the groove for the other end of the blanket, the mechanisms being shielded by a permanently installed gap cover. The latter defines slots along its longitudinal edges aligned with the entryways and through which the ends of the blanket are fed and retracted.
