摘要： A plate cylinder and printing plate holder for the cylinder is provided, which is capable of adjusting relative positions of plural printing plate holders and fixing the printing plate holders on the plate cylinder without causing misalignments of images among printing plates held by the printing plate holders even after overprinting. A plate cylinder (2) is equipped with at least two printing plates (P) wrapped around the outer circumference thereof. The plate cylinder comprises printing plate holders (6, 7) provided each per printing plate (P) for holding the printing plates (P) on the outer circumference of the plate cylinder. The printing plate holders include one printing plate holder (6) provided in a stationary state and fixed against the plate cylinder and other printing plate holders (7) provided adjustable to move in the circumferential direction of the plate cylinder (2) and fixable against the plate cylinder.

摘要： An apparatus for positional adjustment of a plate cylinder in both lateral and circumferential directions thereof for image registration in a multicolor, offset rotary printing press. A lateral adjustment mechanism includes a spur gear which is motor driven bidirectionally, and which travels laterally back and forth, to cause lateral displacement of the plate cylinder. The gear has a pin erected eccentrically thereon for abutment against a fixed limit stop on the press frame in order to limit the bidirectional rotation of the gear and hence to prevent the plate cylinder from being driven laterally beyond limits. A circumferential adjustment mechanism includes another spur gear which is motor driven bidirectionally, and which also travels laterally back and forth, to cause circumferential displacement of the plate cylinder. This second gear has a double-ended pin extending eccentrically therethrough and having its ends projecting in opposite directions therefrom. The double-ended pin is to hit a pair of limit stops on the press frame, which are spaced from each other laterally of the gear, in the event of bidirectional circumferential displacement of the plate cylinder beyond limits.

摘要翻译： 一种印版滚筒在其横向和圆周方向上的位置调整的装置，用于在多色偏移旋转印刷机中进行图像配准。 横向调节机构包括正向电动机驱动的正齿轮，并且横向前后移动，导致印版滚筒的横向位移。 齿轮具有偏心地设置在其上的销，用于抵靠在压机框架上的固定限位挡块上，以限制齿轮的双向旋转，从而防止印版滚筒横向驱动超出限制。 圆周调节机构包括另一正齿轮，该正齿轮是电动双向驱动的，并且还可横向前后移动，以引起印版滚筒的周向位移。 该第二齿轮具有双端销，其偏心地延伸穿过其端部并且其端部从其相反的方向突出。 如果印版滚筒的双向周向位移超出限制，则双端销将在压机框架上相对于齿轮横向彼此间隔开。

摘要： An inking device for feeding ink that is fed to an ink rail to a printing plate on a plate cylinder via a group of rollers that are sequentially in contact with each other, comprising a first roller part of the outer periphery of which faces an ink feeding surface of the ink rail, a second roller that is disposed downstream of the first roller in the ink feeding process and in contact with the outer periphery of the first roller on the downstream side in the rotating direction from the position at which the first roller faces the ink feeding surface of the ink rail, a third roller that is in contact with the first roller on the downstream side in the rotating direction from the position at which the second roller comes in contact with the outer periphery of the first roller, and a fourth roller that is in contact with the outer peripheries of the second and third rollers and blocks the front side in the rotating direction of the first and second rollers at the position where the first and second rollers are in contact with each other; ink droplets and ink particles produced at the contact area of the first and second rollers by the rotation thereof being contained in a space enclosed by the first through fourth rollers.
