e In the register remote adjustment developed by ULTRA-M, A, N, and G, a device for adjusting the first plate cylinder in the axial and circumferential directions and a thermomotor that interacts through the aP Yaderick are attached to the printing device. There is. The respective position of the printing form cylinder within the range of the adjustment stroke is transmitted via a chain transmission to a measuring I-tensionometer connected to the gear block on the display of the operator console. Input of the correction value is performed via a selector switch. The corresponding display value of the console instrument must be added to the detected correction value.

The selector switch is operated until the calculator appears, and at the same time an adjustment operation is performed.

This structure has the disadvantage that high demands are placed on the personnel and that the time required for inputting the correction values is considerable.

In addition, there is a register adjustment device operated from a central control panel (magazine "Der Polygraph" 30 (1977)).

Company g) is publicly known.

A serze motor for axial and circumferential register adjustment is attached to the printing device. The relevant position of the plate cylinder is displayed in digital form on a central console by means of an electrical measuring device. The input of correction values for the adjustment of the plate cylinder is carried out during intermediate calculations by pressing the pushbutton until the correction value appears on the digital display. Adjustment operations are performed simultaneously with the input of correction values.

Even with this structure, high demands are placed on the staff, and the time required to input the correction values is quite long.

A significant disadvantage of the two structures is that they do not take advantage of the registration hole/registration pin method of plate making. This is because there is no fixed reference position that is automatically set for the plate cylinder.

The intention of the present invention is to reduce the number of operations required for printing presses.

The aim is to shorten adjustment time and increase effective capacity.

It is an object of the invention that correction values for register adjustment are related to automatically set plate cylinder reference positions, that inputs are processed simply and clearly in the form of measured values, and that all printing devices He is developing a method by which the adjustment of the plate cylinder can be carried out quickly. Another object of the invention is to provide an apparatus for implementing the above method, which allows IJ alignment operations to be performed with high precision.

This object is achieved according to the invention as follows. In other words, before the start of trial cutting, it is installed in the printing device and the serze motor is activated! By means of the axial and circumferential control devices M, the printing devices ya and y are simultaneously moved to the reference position, and trial cutting is then carried out thereon. During trial cutting evaluation, misregistration belonging to each printing device is detected as a difference in size and direction in the axial direction and/or circumferential direction. This misregistration is used as a correction value for the displacement of the plate cylinder, and is stored sequentially at the time of machine stop t7S: during machine operation using a numerical keypad on the central operation console. The magnitude and direction of the stored correction values are visually displayed on a digital display of the central console as an axial and/or circumferential displacement belonging to the printing device in question. During operation of the machine, the V4!1 operation of each stamp is performed simultaneously on each stamp device. The end of the adjustment operation is visually indicated on the digital display as reaching a value of zero and/or erasing the displayed value. The register adjustment is carried out by assigning to each adjusting device an axial and circumferential adjusting thermomotor. Each servo motor.

A controller sets the plate cylinder reference position and is driven from a central console, interacts with an electronic counting device and is coupled to a self-generator located within said controller.

Next, the present invention will be explained with reference to examples.

The plate cylinder l of a sheet-fed rotary printing press is supported on a side 42 (FIG. 1). Axial and circumferential plate cylinder adjustment.
