ABSTRACT:
An arrangement for securing pure skew adjustment of a cylinder, for example, a plate cylinder in a sheet-fed rotary printing press relative to an adjacent blanket cylinder. A bearing assembly at one end of the plate cylinder includes a cylinder bearing telescoped over the shaft and having flat support surfaces thereon facing radially outward in opposite directions. A guide bearing having a cylindrical outer surface is formed with a central window for receiving the cylinder bearing. The window defines a pair of flat inwardly facing way surfaces spaced parallel to one another for snug reception of the flat support surfaces on the cylinder bearing. The window also defines side walls spaced sufficiently to permit freedom of adjustment of the cylinder bearing along the way surfaces. An eccentric sleeve is fitted between the guide bearing and the frame with means for rockably adjusting the same to move the plate cylinder toward and away from the blanket cylinder thereby to vary the impression. A second adjustment is interposed between the cylinder bearing and the frame for locating the cylinder bearing in a desired position along the way surfaces thereby to adjustably skew the plate cylinder with respect to the blanket cylinder. A key anchored to the frame is provided for holding the guide bearing in a phase position in which the way surfaces therein are constantly oriented perpendicular to a plane which normally contains the axes of the cylinders, notwithstanding the rocking movement of the sleeve.
