摘要： To improve the uniformity of application of damping liquid, typically water, to a plate cylinder (8) of an offset rotary printing machine, a non-contacting, typically spray damper (18) sprays or otherwise applies damping liquid on a damping liquid accepting cylinder (19) with a hard, preferably chrome-plated surface. The damping liquid is applied to the plate cylinder by an application cylinder or roller (21) having a soft, for example rubber or textile surface. A transfer cylinder (20) transfers the water between the accepting roller (19) and the application roller (21). In accordance with the invention, the transfer roller (20) has a soft, for example rubber surface. The soft or rubber surface apparently causes formation of an ink-damping liquid emulsion on the surface thereof which is extremely fine grain to provide a highly uniform coating of damping liquid to the application roller (21). To improve the fineness of damping liquid distribution, more than one (201, 202) such transfer cylinders may be used, each having a soft, typically rubbery surface. Without such soft, rubbery surface transfer cylinders, the minimum number of rollers, for example three (19, 20, 21) would not be possible while still providing a uniform film of damping liquid to the plate cylinder.
摘要翻译：为了提高阻尼液体（通常为水）到偏移旋转印刷机的印版滚筒（8）的均匀性，非接触式典型的喷雾阻尼器（18）将缓冲液喷射到阻尼液体容纳缸（19）具有硬的，优选镀铬的表面。阻尼液通过具有柔软例如橡胶或纺织物表面的施加气缸或辊（21）施加到印版滚筒。传送滚筒（20）在接受辊（19）和施加辊（21）之间传送水。根据本发明，转印辊（20）具有柔软的，例如橡胶表面。柔软或橡胶表面显然导致在其表面上形成一种极其细小的墨水阻尼液体乳液，以向施加辊（21）提供高度均匀的阻尼液涂层。为了提高阻尼液体分布的细度，可以使用多于一个（201,202）这样的转移圆筒，每个具有柔软的，通常是橡胶状的表面。没有这种软的橡胶表面转印滚筒，最少数量的滚子，例如三个（19,20,21）将是不可能的，同时仍向印版滚筒提供均匀的阻尼液膜。

摘要： To permit ready access of operators to printing cylinders located above each other, in which the paper web is introduced laterally towards the cylinders in an upwardly directed path, a guide roller (6) is provided which is held at the end of pivot arms (8) and movable from a position remote from the printing cylinders, so that the upwardly directed path (A) will provide access to an operator standing beneath the then horizontally extending portion of the path, and a position close to the printing cylinders, so that the upwardly extending path (A') will be close to the printing cylinders and permit an operator standing on a movable platform (10) to reach the upper printing cylinders (right side of the figure). The movable platform (10) preferably is hinged upwardly of a platform on which the operator can stand if access to the lower cylinders is desired.

摘要： The invention relates to a drive arrangement for a changeable satellite printing mechanism of a rotary printing machine in which at least two main subject matter printing cylinders, that is, cylinders directly carrying subject matter to be printed, or transfer cylinders, can be selectively engaged with a common counter cylinder or with each other, in which arrangement the main subject matter printing cylinders can be selectively coupled with the counter cylinder or with each other while maintaining registry by selective teeth engagement of one or two sets of cylinder gears secured to the drive shafts of the printing cylinders, and at least one of the two subject matter cylinders is rotatable about a predetermined angle upon shifting of their drive shafts.
