    • An inner sleeve portion in the form of a spacer sleeve is disclosed for being torsionally rigidly mounted on a rotogravure or flexographic mandrel that is to be rotated about its axis when used in a printing machine. The outer surface of the inner sleeve portion torsionally rigidly supports by an interference fit, an outer sleeve portion (the printing sleeve) that carries the printing matrices. The inner sleeve portion has a plurality of air channels extending from the inner surface through the outer surface. Pressurized air flowing through the channels assists in expanding the diameter of the innermost surface of the outer sleeve portion for alternatively mounting the outer sleeve portion onto the inner sleeve portion and dismounting the outer sleeve portion from the inner sleeve portion.
    • 公开了一种间隔套形式的内套筒部分,用于扭转地刚性地安装在轮转凹版印刷或柔性版心轴上,该凹版印刷或柔性版心轴在用于印刷机时绕其轴线旋转。 内套筒部分的外表面通过过盈配合扭转地刚性支撑,承载印刷基质的外套筒部分(印刷套筒)。 内套筒部分具有从内表面穿过外表面延伸的多个空气通道。 流过通道的加压空气有助于扩大外套筒部分的最内表面的直径,以便将外套筒部分可选地安装到内套筒部分上,并将外套筒部分从内套筒部分拆下。

    • A protection ring for a printing sleeve such as a sleeve or cylinder carrying the characters to be printed, or an adapter sleeve for supporting said sleeve or cylinder, the sleeve to be mounted on a rotary mandrel provided with a register pin, can include an annular body to be disposed on an end edge of the sleeve. The body defines a first coupling member for its detachable coupling to the sleeve, which is provided with a second coupling member for cooperating with the first coupling member. The body includes a register notch for cooperating with the mandrel's register pin. The body includes a first orientation element for properly orienting the ring on the sleeve, to enable the ring to be disposed on the sleeve such that the register notch lies in a position suitable for cooperation with the register pin.
    • 用于印刷套筒的保护环,例如承载要打印的字符的套筒或筒体,或用于支撑所述套筒或筒体的适配器套筒,安装在设置有定位销的旋转心轴上的套筒可以包括环形 主体被设置在套筒的端部边缘上。 主体限定了用于其与套筒的可拆卸联接的第一联接构件,其设置有用于与第一联接构件配合的第二联接构件。 主体包括与心轴的对准销配合的对准槽。 主体包括用于使环在套筒上适当地定向的第一定位元件,以使环能够设置在套筒上,使得对准凹口位于适合与对准销配合的位置。

    • An adapter sleeve has an external layer for supporting a printing cylinder carrying data and/or images to be printed. The adapter sleeve has an internal layer defining a bore enabling the sleeve to be mounted onto a rotary mandrel of a printing machine. Each opposite extreme end of the adapter sleeve includes a rigid, load-bearing, radial spacer member disposed between the layers to provide rigidity and indeformability during the use of the sleeve with time. The inner surface of each of the extreme end radial spacer members is defined by rigid and non-deformable material of very low coefficients of dynamic and static friction.
    • 适配器套筒具有用于支撑承载要打印的数据和/或图像的印刷滚筒的外部层。 适配器套筒具有限定孔的内部层,使得套筒能够安装到印刷机的旋转心轴上。 适配器套筒的每个相对的末端包括设置在层之间的刚性的承载的径向间隔件,以在套筒随时间的使用期间提供刚性和不可变形性。 每个极端径向间隔件的内表面由非常低的动态和静摩擦系数的刚性和不可变形的材料限定。
