    • A printing machine has a plurality of rubbing rollers which are rotatable about respective rubbing axes and serve to transfer ink to a form roller. Each of these rubbing rollers is connected via a link to a respective cam follower engaging in a respective continuous circumferential cam groove in a cam that rotates about an axis parallel to the roller axis. The cam follower is normally nonrotatable about the cam but its angular position about the cam can be adjusted so as to closely control the inking characteristic of the respective rubbing roller. The angular position of each rubbing roller is determined by means of a calculator which is set up to hold a diagram on which is plotted the inking density of the material to be printed against the form roller position. A plurality of sliders each corresponding to a respective rubbing roller are independently displaceable on the support adjacent the diagram and each carry indicia indicating the inking characteristic of the respective rubbing roller. These sliders are adjusted for the desired inking characteristic and then each rubbing roller is adjusted so that it is at the angular position indicated by the respective pointer on the respective slider relative to a scale on the calculator support.
    • 印刷机具有多个摩擦辊,它们能绕各个摩擦轴线转动并用于将油墨转印到成型辊上。 这些摩擦辊中的每一个通过连杆连接到在相对于平行于辊轴线的轴线旋转的凸轮中的相应的连续周向凸轮槽中的相应凸轮从动件。 凸轮从动件通常不能绕凸轮转动,而是可以调整其围绕凸轮的角度位置,以便紧密地控制相应的摩擦辊的着墨特性。 每个摩擦辊的角位置是通过计算器来确定的,该计算器被设置为保持绘制相对于成形辊位置的待印刷材料的着墨密度的图。 每个对应于相应的摩擦辊的多个滑块可以在邻近图的支撑件上独立地移动,并且每个进位指示各摩擦辊的着墨特性。 调整这些滑块以达到所需的着墨特性,然后调整每个摩擦辊,使其相对于计算器支撑件上的刻度位于相应滑块上的相应指针所指示的角位置。
