An adjustment device for the cylinders in the printing unit of a printing press, particularly for the blanket or forme cylinder of a printing or varnishing unit in an offset sheet printing press, is described. The cylinder is carried on each side in the frame walls via an eccentric bearings (1). To swivel the eccentric bearings (1), an actuation device acting in common on both is arranged, which can include a print switching device for throwing one cylinder on and off with respect to another, as well as an adjusting device to adjust for differing paper thickness. In accordance with the invention, adjustment means (16-22) are provided enabling one eccentric bearing (1) to be additionally adjusted with respect to the other. This enables the cylinder to be adjusted in parallel with respect to a cylinder cooperating with it and also obliquely thereto, in a fashion actuatable during machine running. The adjustment means may include an adjustment drive (22) fixed to the frame. |
