  • Printing unit with interchangeable printing sleeve
    Patent number: 11390067
    Abstract: The present invention discloses a printing unit with an automated sleeve change process. A sleeve can be prepared for the next printing job while the current job is running, thereby reducing the changeover time. Also, the printing unit can handle printing sleeves of very different sizes without any special additional adjustments to be made. The printing unit translates the printing roller and the inking roller on a horizontal line to engage and dis-engage the printing roller. The invention is convenient for large printing sleeves because the sleeve can be slipped over a shaft that remains in the unit. The setup results in a very rigid system, which guarantees an excellent printing quality.
