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： The invention relates to a device for supplying a shingled or overlapping sheet stream from a stack of sheets of a sheet feeder to a feed table of a sheet-processing machine with a belt table. The belt table is provided with at least one revolvingly driven suction belt, which is in operative connection with at least two suction boxes that can be acted upon by negative pressure. The invention can include a device for taking hold of the sheets. The invention also relates to altering a device so that, independently of the material to be processed, a last sheet of a sheet stream can be easily aligned. This objective is accomplished as follows: after the last sheet is detected and its front edge has been placed against the front guide stops, the operation of the suction belt is stopped.

摘要： A method for cleaning cylinders of rotary printing presses simplifies the changing of cleaning cloths. The exact effective length of the cleaning cloth available for the cleaning process can also be determined in the course of changing the cleaning cloth. A fresh supply roller carrying a fresh cleaning cloth 5 is inserted into the second cleaning cloth depot for replacing the soiled supply roll. The start of the cleaning cloth on the fresh supply roller is fixed in place on a spindle located in the first cleaning cloth depot and the fresh cleaning cloth is wound onto the spindle to form a fresh supply roll while determining the length of cloth wound on the spindle. The end of the fresh cleaning cloth remains in the second cleaning cloth depot and now forms the receiving roll during the cleaning process.

摘要： The drive for the multicolor rotary press has a main drive shaft, a connected synchronized gear train which extends substantially parallel to the drive shaft and which connects the press mechanisms with each other and a torsion spring-rod which couples the main drive shaft and the synchronized gear train. For coupling the main drive shaft with the synchronized gear train the torsion spring-rod is mounted on an axle journal of a press cylinder. To provide a drive for operation of the press at several different operating speeds a force-locking or frictionally-engaging coupling clutch is mounted on bevel gear shafts located between the press cylinder of one press mechanism drivable by a torsion spring-rod and another press cylinder of an adjacent press mechanism carrying a transversely moving linkage. One of the bevel gear shafts is driven by another gear coupled with the main drive shaft, so that, when the clutch is engaged, particularly at start-up and low speed operation, the press cylinders are driven without the torsion spring-rod, but when the clutch is disengaged, the press cylinders are driven through the torsion spring-rod thus damping oscillations due to gear teeth tolerances.

摘要： An ink metering method for an inking mechanism of a rotary printing machine having an ink fountain, a doctor roller, a separate electric motor for driving the doctor roller and a low speed of rotation relative to the printing machine, includes the selection of a rate at which the electric motor imparts to the doctor roller discrete angular motions; and selecting by a second selector switch the magnitude of the angular motions. A circuit arrangement for carrying out the method includes a time selection unit which delivers at its output a series of pulses at a desired rate; an increment evaluation unit which receives at its input a number of pulses corresponding to the magnitude of the angular motion performed by the electric motor and compares the momentary number with a preset desired number corresponding to a desired magnitude of the angle of rotation.

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 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.
