ABSTRACT:
An arrangement for securing impression as well as skew adjustment of one cylinder relative to another in a printing press. One of the cylinders has a bearing assembly occupying a cylindrical opening in the press frame. The bearing assembly includes a cylinder bearing having parallel planar support surfaces on opposite sides. An annular eccentric guide bearing has a cylindrical outer surface which is fitted into the cylindrical opening in the frame. The guide bearing is provided with opposed parallel way surfaces perpendicular to the plane containing the axes of the cylinders for slidably receiving and supporting the cylinder bearing. A first adjustment is provided for rockably positioning the guide bearing. The cylindrical opening in the frame has an axis which is offset, in a direction parallel to the way surfaces, from the axis of the cylinder bearing so that as the guide bearing is rockably adjusted the first cylinder is moved toward and away from the second cylinder thereby to vary the degree of impression. A second adjusting means is interposed between the cylinder bearing and the frame for positioning the cylinder bearing along the way surfaces thereby to adjustably skew the first cylinder with respect to the second. In the preferred form of the invention the parallel way surfaces are defined by a diametrical open-ended slot formed in the guide bearing.
