Abstract From the Canadian patent

A printing blanket holding bar and printing blanket assembly using the same are provided herein. The holding bar comprises a substantially U-shaped member having a bight and a pair of legs extending from opposite ends of the bight and a blanket clamping arm carried by the bight. The arm is adapted to cooperate with the bight to fix an associated end portion of a printing blanket therebetween with the legs being adapted quickly to attach and to detach the holding bar relative to a bar support. Each of the pair of holding surfaces when they are employed, are the sole means for holding the bar on the bar support. This assures operation of an associated printing press with a minimum down time.
