Abstract (en)
[origin: US5167187A] A throw-on and throw-off device for a blanket cylinder in the printing unit of an offset press is provided wherein the blanket cylinder is mounted at both its ends in eccentric bushings and the pivoting throw-on/throw-off movement of the bushings is produced by a toggle-like linkage. Two parallel double-acting fluid pressure cylinders are connected by way of their piston rods to a cross link which is pivoted to one of the links of the toggle linkage. The two pressure cylinders can be individually supplied with compressed air either consecutively or simultaneously so that, in the first case, precise sequential throw-on of the blanket cylinder on the plate cylinder and subsequently on the impression cylinder can be achieved and, in the latter case, there can be a very rapid throw-off of the blanket cylinder from both the impression cylinder and the plate cylinder.
