  • Patent number: 4200045
    Abstract: A loading arrangement for obtaining an equally distributed pressure load in a cylinder stack included in a printing unit of an offset printing press, comprising a plurality of cylinders each having a cylindrical body portion and stub shafts at both ends, journalled in bearings. The arrangement includes axially short load rollers for producing a pressure load to the outermost cylinders of the stack. The rollers are located to act on portions between the bearings of the cylinders, and hence, the pressure load is transmitted directly to the body portions of the outermost cylinders. This minimizes the deflection of the cylinders.
