脱开状态橡皮布滚筒运动程度不同的印刷单元及印刷机
摘要：
一种用于印刷卷筒纸(3)的印刷单元(7至14)包括机架(28)以及至少上侧印刷组(20A)和下侧印刷组(20B)。每个印刷组包括橡皮布滚筒(22A，22B)和印版滚筒(24A，24B)。印刷单元还包括滚筒支撑和移动机构(26)，该移动机构使得印刷单元具有使橡皮布滚筒(22A，22B)彼此相互抵靠并且抵靠在印版滚筒上(24A，24B)的至少一个滚筒接触状态以及使橡皮布滚筒(22A，22B)彼此分开的至少一个滚筒脱开状态。在滚筒脱开状态，上侧橡皮布滚筒(22A)相对于其在滚筒接触状态中的位置被抬升第一高度(h1)，下侧橡皮布滚筒(22B)相对于其在滚筒接触状态中的位置被降低不同于第一高度的第二高度(h2)。所述印刷单元适用于例如印刷书籍的胶印机。
摘要（英）：

A printing unit for printing a web of paper is provided. The printing unit includes a frame and at least an upper printing group and a lower printing group, each printing group including a blanket cylinder and a plate cylinder. The printing unit also including a cylinder support and movement and having at least one throw-on configuration in which the blanket cylinders are pressed against each other and against the plate cylinders, and at least one throw-off configuration in which the blanket cylinders are spaced apart from each other. In the throw-off configuration, the upper blanket cylinderhas been raised by a first height relative to the position which it occupies in a throw-on configuration, and the lower blanket cylinder has been lowered by a second height relative to the position which it occupies in a throw-on configuration, and the second height is different from the first height. The printing unit is suitable to offset point machine such as book printing.
