摘要： A clamping device of a plate cylinder for recessed in-line varnishing in a rotary press which comprises two axis-parallel clamp bars having a top part and a bottom part, which are circumferentially adjustable in a parallel or an inclined relationship to one another in guides by means of clamp screws bearing against the plate cylinder, and which are axially adjustable by means of axial setscrews, and having a groove extending over the entire length of the clamp bars in the bottom part which provides for the insertion and fixing of reinforced bent ends of the blanket, and the top part is pivotally and slidably connected to the bottom part by locking devices and recesses for the clamping screws, and additional centering means are provided for at least two of the clamping screws.

摘要： A sheet gripper for a rotary press is provided having a hooked gripper finger pivotably connected at its lower end to a clamping element, and a roller disposed upon the gripper finger is biased against the guiding surfaces of a finger support element to ensure smooth changes from open and closed gripper finger positions, substantially without any vibrational motion or displacement resulting in the plane of sheet motion. Preferably, a compression spring is mounted in the clamping element to bias the roller against the gripper support element, the element having a rectilinear guide surface disposed substantially perpendicularly to a retaining surface, and a cam surface which extends upwardly and inclined outwardly from the rectilinear guide surface. Upon oscillation of the gripper shaft, the roller is guided along the rectilinear guide surface and cam surface, thereby defining accurate gripper finger motion.

摘要： A roller cleaning device for a varnishing system in a printing press has liquid-supplying means pivotally arranged above the rollers conveying varnish. The spatial distribution of the liquid-supplying means differs over the length of the rollers. The liquid-supplying means are closer together in two edge zones than in the central zone; the liquid-supplying means in the central zone have nozzles that are spaced apart from one another at a relatively large interval. The liquid-supplying means come into operation at stopping and at the onset and cessation of printing. The liquid-supplying means in the edge zone operate, in accordance with format width, throughout printing.
