摘要： 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.

摘要翻译： 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。

摘要： An ink or liquid pickup roller is partially immersed in a bath of liquid and is rotated about a horizontal axis in one rotational sense. An applicator roller spaced from the pickup roller is rotated about its horizontal axis in the same rotational sense. A transfer roller is rotated in the opposite rotational sense about its horizontal axis and radially continuously engages the applicator roller. This transfer roller also is oscillated about the axis of the applicator roller into periodic contact with the roller to receive therefrom a coating of ink or other printing liquid. The transfer roller therefore rolls off the pickup and applicator rollers, but the peripheral velocities of the transfer roller is different from the peripheral velocities of the pickup and the applicator rollers.

摘要翻译： 墨水或液体拾取辊部分地浸没在液体浴中，并且在一个旋转方向上围绕水平轴线旋转。 与拾取辊间隔开的涂布辊绕其水平轴线以相同的旋转方向旋转。 转印辊绕其水平轴线以相反的旋转方向旋转，并且径向地连续地接合涂布辊。 该转印辊也绕着施加辊的轴线摆动，与辊子定期接触，从而接收油墨或其它印刷液体的涂层。 因此，转印辊滚动拾取器和涂布辊，但转印辊的圆周速度不同于拾取器和涂布辊的圆周速度。

摘要： An arrangement for facilitating the mounting of printing plates on a plate cylinder of an offset printing machine. Two arms are mounted atop the machine at the opposite lateral sides thereof and have free ends provided with hooks. A rail is suspended from these hooks and carries quick-coupling devices which engage the trailing edge of a printing plate to be mounted. The hooks are suspended on ropes which are wound upon rollers mounted on the free ends of the arms; turning of the rollers in a sense causing unwinding of the ropes is resisted by torque springs or similar devices; this resistance can be varied to compensate for printing plates of different weights. Thus, the weight of the printing plate cannot cause the ropes to unwind; however, when the leading edge of the printing plate is connected to the plate cylinder and the cylinder is slowly rotated to take the plate up on it, the pull exerted by the cylinder causes unwinding of the ropes.

摘要： A four-bar kinematic chain has an input member which includes a portion formed with a guide channel, an elongated output member that is pivoted intermediate its end portions, and a link member having one end pivoted to one end portion of the output member and another end portion provided with a sliding block received in the guide channel. A crank drive is connected with the input member for oscillating the same and the guide channel, to thereby effect oscillatory movement of the other end portion of the output member and concomitant movement of an element to which the other end portion is coupled. An arrangement is provided for arresting the sliding block at selected locations in the guide channel, to thereby permit a variation in the stroke and frequency of the movements of the other end portion of the output member.

摘要： A plate clamping device for clamping flexible printing plates in rotary printing machines includes an upper guiding rail and a lower guiding rail to receive and clamp a printing plate therebetween. The device is provided with two spaced from one another bolts and a clamping arrangement centrally positioned between said bolts. The clamping arrangement includes an eccentric stud extending normally to the elongation of the lower rail and a wedged key mounted between the upper rail and the stud. The stud has a surface having a flat portion, a transition curved portion and a cylindrical portion. The wedged key is arranged in engagement with this surface and upon rotation of the stud the key may rest on the flat portion of the stud when the device is in a plate-releasing position or the key may engage with the cylindrical portion of the stud whereby the key is self-arrested and the rails clamp a printing plate.

摘要： The liquid-distributing roller assembly for printing machines is composed of two opposite pairs of guiding tracks secured to the machine walls. One track supports for rectilinear movement a two-stage transmission gear unit in which one end of the shaft is supported for rotation; the other end of the shaft is supported for rotation and for a rectilinear movement in the opposite track. The shaft supports for rotation and for an axial displacement a liquid distributing roller which at one end is connected to a first spur gear rotatable on one end of the shaft and being in permanent engagement with an elongated transmission gear. The latter is also in permanent engagement with a second spur gear which is connected for joint rotation to the shaft. The other end of the shaft supports a cam which engages a cam follower connected to the distributing roller so that as soon as the latter is rotated an axial reciprocating movement is generated by the cam mechanism.

摘要： A printing press is provided with a safety device mounted in the vicinity of a gap formed between two counter printing rollers for preventing the gap from intrusion by foreign elements, such as a mop or the hand of an operator. The device includes a four-link transmission unit operatively interconnected between pivotable guard plates and a cam switch adapted to actuate an end switch of the printing press to shut the latter off. The guard plates are swung away from the rollers so that the gap is enlarged.

摘要： An operator safety device includes a plurality of covers for covering parts of a machine to protect an operator against contact with these parts when the machine is in operation. At least some of the covers are movable between a closed position where the covers do not cover these parts and the latter are readily accessible and constitute a danger of accidents. A switch is operable for shutting down the machine when at least one of the covers moves from the closed into the open position. A linkage connects the covers with the switch for actuating the latter whenever at least one of the covers moves from the closed into the open position.
