  • Device for shifting oscillating rollers in a printing machine
    Patent number: 5134939
    Abstract: An oscillating roller for offset printing machines has a central shaft fitted for appropriate rotation into a frame of the machine, and a concentric oscillating cylinder. A cotter fitted on the cylinder engages in a guiding groove of the shaft in order to ensure common rotation of the two components without preventing their respective axial shifts. Two chambers made up by the cylinder and the shaft can be alternatively subjected to hydraulic pressure in order to cause the cylinder to shift axially in the one or the other direction.
