    • Intaglio printing cylinder, comprising a core of a virtually undeformable material and a multilayer sleeve joined releasably thereto. The new intaglio printing cylinder especially is more durable than prior cylinders of a similar type, and it is interchangeable with conventional solid metal intaglio printing cylinders. The new intaglio printing cylinder is characterized by the fact that on the outside of the first, inner layer of the sleeve a plurality of ribs projecting outwardly and running substantially in the longitudinal direction of the cylinder are disposed. This intaglio printing cylinder has an improved stability, especially against circumferential shifting or displacement within the sleeve and thus is more durable. An additional improvement of its working characteristics is achieved by a continuous electrical continuity from the core to the outer copper layer. The new intaglio printing cylinder is especially suitable as a substitute for the solid metal printing cylinders still in use. It offers the advantage that, with a single core, a plurality of sleeves of different outside diameters can be used.
    • 凹版印刷滚筒包括几乎不可变形材料的芯和可释放地连接到其上的多层套筒。 新的凹版印刷滚筒特别比现有类似类型的滚筒更耐用,并且可以与传统的固体金属凹版印刷滚筒相互替换。 新的凹版印刷滚筒的特征在于,在第一套筒的外侧设置有沿着圆筒的纵向方向向外突出并且大致沿着圆柱体的纵向延伸的多个肋。 这种凹版印刷滚筒具有改进的稳定性,特别是对于套筒内的周向移动或位移,因此更耐用。 通过从芯到外部铜层的连续电连续性,可以进一步提高其工作特性。 新的凹版印刷滚筒特别适用于仍在使用的固体金属印刷滚筒的替代品。 其优点在于,使用单个芯,可以使用多个不同外径的套筒。

    • 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.
    • 公开了一种印刷辊,其包括具有中心中空管状部分和两个外部轴颈部分的三件式心轴组件。 每个轴颈部分具有形成在其中的液压流体通道和周向地安装在其上的圆柱形套筒,其内表面适于被液压流体系统加压。 可移动的中空印刷滚筒可滑动地安装在三件式心轴上,并且通过在安装在每个轴颈上的圆柱形套筒上施加液压而摩擦地保持在外部轴颈位置。

    • A printing roll is mounted in a printing machine in such a way that a sleeve on its outer surface can be removed axially while the roll remains substantially in its working position. One end bearing of the roll is free of axial restraint relative to the roll and is removably secured to a side frame of the machine. For axial positioning, an adjustable restrainer engages the roll axle at that end. Beyond the other side frame a counterpoise acts on the roll axle to support the roll when the one end bearing is removed. The counterpoise may be a hydraulically operated pull roll, permanently engaged to the roll axle through a yoke and a rolling contact bearing.
    • 印刷辊安装在印刷机中,使得其外表面上的套筒可以轴向地移除,同时辊保持基本上处于其工作位置。 辊的一端轴承相对于辊没有轴向约束,并且可移除地固定到机器的侧框架上。 对于轴向定位,可调限制器在该端接合辊轴。 在另一侧框架之外,当移除一端轴承时,平衡杆作用在辊轴上以支撑辊。 平衡阀可以是液压操作的拉辊,通过轭和滚动接触轴承永久地接合到辊轴。
