Abstract
An apparatus for the print throw-on and throw-off of the rubber blanket cylinder in the printing unit of a sheet-fed offset printing machine is described. For the throw-on and throw-off of the rubber blanket cylinder in relation to the impression cylinder and to the plate cylinder, the rubber blanket cylinder is mounted pivotably on both sides in eccentric bearings. The pivoting of the eccentric bearings takes place via two individually switchable actuating means, a print regulation mechanism being connected in series up from the actuating means. The two actuating means act on the eccentric bearings via a ternary member for the pivoting of the eccentric bearings, this arrangement selected in this way making it possible, in the case of larger thicknesses of printing material, to throw off the rubber blanket cylinder only from the plate cylinder. The print throw-off and throw-on thus causes lower torque jolts because of the smaller pivoting travel.
