Abstract
A printing roller is disclosed comprising a three-piece mandrel assembly having a central hollow tubular section and two outer journal sections. Each journal section has hydraulic fluid passageways formed therein and a cylindrical sleeve circumferentially mounted thereon, the inner surface of which is adapted to be pressurized by the hydraulic fluid system. A removable hollow printing cylinder slidably is mounted onto the three piece mandrel and is frictionally held at the outer journal locations through the application of hydraulic pressure upon the cylindrical sleeves mounted upon each journal.
