    摘要： A vacuum drum assembly for a printing machine comprises a drum having an array of passageways distributed along its length and around its periphery to permit air to flow from outside the drum to inside the drum in response to reduced air pressure inside the drum, and an array of valve members, each valve member being movable between a closed position in which that valve member restricts at least one of the passageways and an open position in which the restriction of that passageway or those passageways is reduced. The arrangement is such that, when a partial area of the drum is wrapped with a sheet of material, at least some of the valves for the passageways adjacent the edges of that area are open, and the valves for the passageways which are not covered by the sheet and are not adjacent the edges of that area are closed. The open area of the drum is regulated such that it is small in regions where there is no paper. Accordingly, the open area of the drum is adapted to the shape and size of the paper and the position of the paper on the drum, while minimizing the required suction flow. A duplex printing machine comprises two such vacuum drum assemblies with their drums parallel. The air pressure inside the drums is reduced and the drums are counter-rotated. Material to be printed on is fed to the first drum so that the material can be held on the first drum by vacuum and rotated therewith, and a first print head prints on one side of the material. The material is then released from the first drum in a direction towards the second drum so that the material can be held on the second drum by vacuum and rotated therewith. A second print head then prints on the material on the second drum. The material is then released from the second drum.

    摘要翻译： 用于印刷机的真空鼓组件包括一个滚筒，该滚筒具有沿其长度和周围分布的通道阵列，以响应于滚筒内的减小的空气压力使得空气从滚筒外部流动到滚筒内部;以及阵列 的阀构件，每个阀构件可以在闭合位置之间移动，在关闭位置中，该阀构件限制至少一个通道和在该位置中限制该通道或那些通道的打开位置。 该布置使得当滚筒的一部分区域被一片材料包裹时，用于与该区域的边缘相邻的通道的至少一些阀是打开的，并且用于通道的阀不被 该片材并且不邻近该区域的边缘是封闭的。 鼓的开放区域被调节为使得在没有纸张的区域中它是小的。 因此，滚筒的开口面积适应于纸张的形状和尺寸以及纸张在滚筒上的位置，同时最小化所需的抽吸流量。 双面打印机包括两个这样的真空鼓组件，它们的鼓平行。 鼓内的空气压力减小，鼓反向旋转。 要印刷的材料被馈送到第一鼓，使得材料可以通过真空保持在第一滚筒上并与之一起旋转，并且第一印刷头在材料的一侧上印刷。 然后将材料从朝向第二滚筒的方向从第一滚筒释放，使得材料可以通过真空保持在第二滚筒上并与之一起旋转。 然后，第二打印头在第二鼓上的材料上打印。 然后将材料从第二鼓释放。
