For example, the characterizes from a z. B. two-digit number existing identifier "12" with its first digit marked with the number "1" roller lock 21, which in which in the Fig. 1 to 4 shown example of the dampening roller 04 is assigned, wherein in the number sequence with the second digit, which has been selected here as the number "2", a specific actuator 22 is meant in the roller lock 21 marked with the number "1". The identifier "15" in this example indicates the fixing device of the roller lock 21 marked with the number "1" Fig. 1 to 4 In the example shown, the identifier nm relates digit sequences with a first identification feature n with a number between "1" and "6" because six mutually different roller locks 21 are provided, and with a second identification feature m with a number between "1" and "5""for each four actuators 22 per roller lock 21 and the associated fixing device. Characterized in that in the printing unit 01 each roller lock 21, each of its actuators 22 and each fixing device is assigned an identifier nm, each roller lock 21, each actuator 22 and each fixing device can be clearly identified and addressed. The identifiers nm can z. B. in the control unit each be stored as an individual, unique address, whereby each roller lock 21, each actuator 22 and each fixing device by the control unit individually and independently of other arranged in the printing unit 01 roller locks 21, actuators 22 and fixing devices selected, selected can be addressed and controlled.

If both ends 18 of the same adjustable in the contact pressure and / or variable in position roller 04; 06; 07; 08; 09; 11 and / or at least one end 18 of two different respectively adjustable in the contact pressure and / or variable in position rollers 04; 06; 07; 08; 09; 11 each in a support bearing 21, that is mounted in a roller lock 21, with a radially displaceable roller receptacle 39, wherein each support bearing 21 at least one on the roller 04; 06; 07; 08; 09; 11 acting actuator 22, the control unit controls at least the actuator 22 of at least two support bearings 21 individually and independently of other support bearings 21 and actuators 22. The control unit thus controls at least one actuator 22 of a support bearing 21 individually and independently of an actuator 22 of another support bearing 21. The control unit may also groups of actuators 22 and support bearings 21 in common control, especially when these jointly controlled actuators 22 and support bearings 21 form a functional composite, so are always and inevitably set in a fixed relationship to each other due to their technical function in the printing process.

The at least two actuators 22 of each roller lock 21 are always arranged the same with respect to a specific position of the roller lock 21 in each roller lock 21 in its preferably circular distribution, so that in all roller locks 21 of a printing unit 01, the identification feature m of their actuators 22 and fixing always in can be assigned to the same order. Accordingly, for identically positioned actuators 22 in this order, the same identification feature m is always assigned. For example, the actuators 22 and fixing device are marked in an ascending order, wherein in this order for the fixing device, the identifier z. B. is awarded the highest value. Thus, the actuators 22 in each roller lock 21 are marked in a fixed sequence. For example, starting from a specific position on the circumference of the roller lock 21, the actuators 22 in each roller lock 21 in the circumferential direction in the same fixed order.

The actuators 22 are in each roller lock 21 in their preferred pneumatic execution in each case by a pressure medium line 41 with a pressure level 42 having a pressure medium source, for. As a compressor connected. Like in the Fig. 7 can be provided that are arranged in different roller locks 21 actuators 22, which have the same identification feature m in their respective arrangement in the respective roller lock 21, connected in a parallel circuit with the same pressure medium line 41 to the same pressure medium source or at least at the same pressure level 42 , Also arranged in the same roller lock 21 actuators 22 with a distinctive identification feature m with different pressure medium lines 41st connected to different pressure medium sources or at least at different pressure levels 42.

It can be provided that the actuators 22 arranged in the roller locks 21 are always pressurized and that the pending pressure only in the sense of a displacement of the controllable roller 04; 06; 07; 08; 09; 11 and / or to be changed on the controllable roller 04; 06; 07; 08; 09; 11 exerted contact force, if and as long as the fixing device of the relevant roller locksmith 21 is released, d. H. in the displacement of the controllable roller 04; 06; 07; 08; 09; 11 permitting operating position is located. If and as long as the fixing device of the relevant roller locksmith 21, the displacement of the controllable roller 04; 06; 07; 08; 09; 11 blocks, at least one of the actuators 22 pending pressure or a change in the pressure applied there does not affect the controllable roller 04; 06; 07; 08; 09; 11 off. If and as long as an effect on the controllable roller 04; 06; 07; 08; 09; 11 is not intended, the pressure medium lines 41 to the with this roller 04; 06; 07; 08; 09; 11 interacting actuators 22 are provided at least partially also without pressure or at least considerably reduced pressure as an alternative to their constant pressurization.

Preferably, with the same in their contact force controllable roller 04; 06; 07; 08; 09; 11 connected roller locks 21 on the same number of actuators 22 on. As in the example described here, the roller locks 21 of several or even all in each case in their contact force controllable rollers 04; 06; 07; 08; 09; 11 have the same number of actuators 22. In a printing unit 01 is usually a rack wall 36, in or at each of which a first bearing for the controllable in their contact force rollers 04; 06; 07; 08; 09; 11 and their adjacent rotary body 12; 13; 14; 16; 17, as "side I" and the opposite frame wall 36, each with a second bearing for the controllable in their contact force rollers 04; 06; 07; 08; 09; 11 and their adjacent rotary body 12; 13; 14; 16; 17 referred to as "page II".

According to the state of the art, actuators 22 engage with the same roller 04; 06; 07; 08; 09; 11 associated roller locks 21 a at both ends 18 of this roller 04; 06; 07; 08; 09; 11 in the same amount of pressing force in the roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 on the adjacent rotary body 12; 13; 14; 16; 17 off. However, if designed as a forme cylinder 12 rotational body 12 is not uniformly occupied in its axial direction with printing plates, but the forme cylinder 12 z. B. is occupied only in half or at least not consistently with printing plates, it is advantageous that at the two ends 18 of the same roller 04; 06; 07; 08; 09; 11 to be applied to the forme cylinder 12 applied contact pressure in the amount different. Thus, the vector sum of the radial forces Fn1 differs; Fn2; Fn3; Fn4 of the actuators 22 in the roller lock 21 on the "side I" of the vector sum of the radial forces Fn1; Fn2; Fn3; Fn4 of the actuators 22 in the roller lock 21 on the "side II".

In the in the Fig. 7 shown example of a pneumatic circuit of the actuators 22 of all arranged in the printing unit 01 roller locks 21 determine in the outgoing from a pressure medium source pressure line 41, preferably electrically or electromagnetically operated controllable devices, preferably as fast reaction proportional valves EP1; EP2; or EP3; EP4, z. B. 3/3-way proportional valves EP1; EP2; EP3; EP4 are formed, the pressure level 42 which is applied to the respective actuators 22, wherein z. B. each roller lock 21 of one of the proportional valves EP1; EP2; EP3; EP4 is assigned, wherein the control unit arranged in the roller locks 21 actuators 22 by means of the proportional valves EP1; EP2; EP3; EP4 actuated. With two further controllable devices provided in the circuit, preferably as electrically or electromagnetically actuated valves EP5; EP6, z. B. 5/2-way valves, are formed in the pressure line 41 on the way of the pressure medium from its pressure medium source to the actuators 22 in one Series connection in each case one of the proportional valves EP1; EP2; EP3; EP4 are arranged, can be selected whether actuators 22 on the "side I" of the controllable in their contact force roller 04; 06; 07; 08; 09; 11 with the same pressure as on the "side II" or with a different pressure applied. The pressure level 42 can with the proportional valves EP1; EP2; EP3; EP4 to any value z. B. between 0 bar and 10 bar, preferably between 0 bar and 6 bar, are set.

The fixing of roller locks 21 of the same roller 04; 06; 07; 08; 09; 11 are in their respective pressure line 41 z. B. connected in parallel and thus change their operating position preferably simultaneously. Preferably also electrically or electromagnetically operated valves V15; V25; V35; V45; V55; V65, z. B. 3/2-way valves V15; V25; V35; V45; V55; V65, each fixing device is optionally in a first operating position, in which the fixing device, the substantially radial displacement of the controllable in its contact force roller 04; 06; 07; 08; 09; 11 locks, or in a second operating position in which the fixing device, the substantially radial displacement of the controllable in its contact force roller 04; 06; 07; 08; 09; 11 releases brought.

Alternatively or in addition to that in the Fig. 7 shown wiring of the actuators 22 each roller lock 21 each be assigned a controllable device, wherein the controllable device each more, preferably all, connected to their respective pressure medium source pressure lines 41 of actuators 22 of the same roller lock 21 each simultaneously in a first operating position with a first pressure level 42nd and pressurized in a second operating position with a second pressure level 42, wherein in each of the two operating positions, the respective pressure level 42 present on the actuators 22 is different from zero for at least one of the actuators 22 of the same roller lock 21. All actuators 22 of the same roller lock 21 are thus at the same time each with their respective, preferably in the two operating positions of the controllable device from each other differing pressure level 42 pressurized. In the two operating positions of the controllable device, the pressure level 42 respectively present at several or all of the actuators 22 of the same roller lock 21 is also completely different, so that the actuators 22 of the same roller lock 21 are each pressurized with a different pressure level 42. Actuators 22 identified in the same identification feature m in different roller locks 21 can have the same pressure level 42, whereas actuators 22 of the same roller lock 21 with differing identification features m generally have different pressure levels 42. The change between the first operating position and the second operating position preferably takes place abruptly by a switching operation of the controllable device triggered by the control unit. The controllable device therefore acts on all actuators 22 of the same roller lock 21 leading pressure medium lines 41 equally and can, for. B. by a check valve with a plurality of mutually independent passages or more synchronously, ie simultaneously switching shut-off valves or a switching position of the proportional valves EP1; EP2; EP3; EP4 be realized. Since the setting of all involved in the change actuators simultaneously, that is performed synchronously, the setting is carried out by a roller 04; 06; 07; 08; 09; 11 in a roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 on an adjacent rotary body 12; 13; 14; 16; 17 applied pressing force quickly, ie within a very short time duration. As a result, when the inking unit 02 or dampening unit 03, in particular during an ongoing production of the printing unit carried out changing the setting an unstable, tends to oscillate operating state. If several each mounted in roller locks 21 rollers 04; 06; 07; 08; 09; 11 are provided, each roller lock 21 having an identification feature n, the control unit selects the each roller lock 21 associated controllable device in each case on the basis of the identification feature n.

The printing unit 01 can with respect to the rollers 04; 06; 07; 08; 09; 11 exercised Pressing forces have a standard configuration, the standard configuration having a set of values FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62, where each value is FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 with one of a roller 04; 06; 07; 08; 09; 11 of this printing unit 01 in a roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 on a respective roller 04; 06; 07; 08; 09; 11 adjacent rotational body 12; 13; 14; 16; 17 applied contact force corresponds. The standard configuration can consist, for example, of numerical values, value pairs or value series stored in a table or graph, wherein the control unit accesses these numerical values, value pairs or value series by means of a program running in the control unit for setting a desired contact pressure and these numerical values, value pairs or value ranges for adjustment used the desired contact force.

In the in the Fig. 1 . 2 and 7 example shown are in the printing unit 01 six controllable in their contact force rollers 04; 06; 07; 08; 09; 11 with a total of twelve roller strips N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 provided, each controllable in its contact force roller 04; 06; 07; 08; 09; 11 is mounted in each case in a roller lock 21, each with four actuators 22. Taking into account the possibility of being able to set differing pressing forces on the "side I" and on the "side II" of the printing unit 01, the standard configuration for this printing unit 01 can be a set of twenty-four values FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; Include FN62. For each of these roller strips N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 becomes the value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 of the respective contact force exerted there on a vector sum of the radial forces Fn1 exerted by actuators 22 of the same roller lock 21 at the same time; Fn2; Fn3; Fn4 optionally taking into account the controllable by their contact force roller 04; 06; 07; 08; 09; 11 due to their own mass on their neighboring Rotating body 12; 13; 14; 16; 17 formed at least partially exerted weight. Thus, each value is FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 for each of the contact forces five further values resulting from the four radial forces Fn1; Fn2; Fn3; Fn4 and optionally the mass of the controllable roller 04; 06; 07; 08; 09; 11 composed, assigned. Moreover, each value for a radial force Fn1; Fn2; Fn3; Fn4 be divided into an indication of their absolute value and direction of action.

The values FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 in the roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied contact forces, their respective assigned values for the radial forces Fn1; Fn2; Fn3; Fn4, preferably divided into magnitude and effective direction, and optionally the mass of the controllable rollers 04; 06; 07; 08; 09; 11 are preferably stored in a memory of the control unit. Likewise, the value of the gravitational constant for calculating the weight force from the mass of the controllable roller 04; 06; 07; 08; 09; 11 and for each in its contact force controllable roller 04; 06; 07; 08; 09; 11 each a value for the distance of the lying on its axis 19 midpoint of the roller 04; 06; 07; 08; 09; 11 from the center of its respective adjacent rotational body 12 in contact with it; 13; 14; 16; 17, wherein each value for one of the distances can be divided into an indication of the absolute value and the spatial direction.

In the standard configuration, due to the values stored in the memory of the control unit for the contact forces, FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 in touching contact between each other employed in their contact force controllable rollers 04; 06; 07; 08; 09; 11 and rotating bodies 12; 13; 14; 16; 17 on the roller 04; 06; 07; 08; 09; 11, on the rotary body 12; 13; 14; 16; 17 or at both a certain measure of the flattening of their respective cylindrical Lateral surface, wherein the chord of the flattening of the circumference of the roller 04; 06; 07; 08; 09; 11 or the rotating body 12; 13; 14; 16; 17 extending width of the roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 corresponds. The default configuration produces a degree of flattening that corresponds to a particular setpoint for the width of each roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 corresponds to the printing unit 01 under standard operating conditions to achieve a good quality for the printed product to be produced.

For non-standard operating conditions, because the diameter of one of the controllable in their contact force rollers 04; 06; 07; 08; 09; 11 or the diameter of one of the rotary bodies 12; 13; 14; 16; 17 z. B. swollen by a cloth inclusion, in particular by a moisture absorption, or has been reduced by wear, it is necessary to change due to the change in the diameter width of a roll strip or a plurality of roll strips N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; Correcting N62 so that the width of each roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 again corresponds to their nominal value. On the other hand, the operating conditions may also require that the width of each roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 is set to a new setpoint. In both cases, the roll strip N11 involved in each affected strip is; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied to a new value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62, with the result that values for the radial forces Fn1; Fn2; Fn3; Fn4 of the affected roller locks 21 are to be changed.

The control unit has at least one control element and z. B. via a display device for displaying one or more values FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 for those in a particular Roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied contact pressure. The reference numerals of the roller strips N11 selected here by way of example; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 may also be simultaneously identified as an identifier for the roller strips N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 can be used so that each roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 is clearly identifiable due to its identifier.

With the z. B. as a button, as a keyboard or as a pointer instrument formed control element of the control unit, a specific roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 z. B. from a list of all provided with an identification roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 of a printing unit 01 are selected or the identifier of a specific roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 is input to the control unit with its control. To each of these roller strips N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 is a value FN11 in the memory of the control unit, at least for the standard configuration; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62, in particular a setpoint for which in the roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied contact force stored. This value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 is used in selecting or entering the identifier of a particular roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 with the z. B. alphanumeric or graphics capable display device z. As numeric, alphanumeric, displayed in a diagram or in a pictogram.

The control element displays the displayed value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 for those in the roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied force to a new Value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 for those in the roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied pressing force by the displayed value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 z. B. continuously or stepwise, preferably in steps of 10% of the displayed value, is changed with the control. Or, the control selects from a list of available factors a certain factor by which the displayed value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 should be changed.

The control unit calculates FN11 for the new value; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 in the selected roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied force the associated values for the force exerted in the roller lock 21 radial forces Fn1; Fn2; Fn3; Fn4 and / or the pressures to be respectively set in the actuators 22 and stores the calculated values for the radial forces Fn1; Fn2; Fn3; Fn4 and / or the pressures in their memory. Likewise, the control unit also controls the valves V15; V25; V35; V45; V55; V65, the proportional valves EP1; EP2; EP3; EP4 and the valves EP5; EP6. Carrying out the calculation of new values FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 and / or the control of the valves V15; V25; V35; V45; V55; V65, the proportional valves EP1; EP2; EP3; EP4 and / or the valves EP5; EP6 is preferably carried out after the control unit to a certain, z. B. with the control input or selectable instruction has received.

The calculation of new values FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 for the contact forces takes into account that these values and the radial forces Fn1; Fn2; Fn3; Fn4 in their original and new states are each considered to be a vector size. Accordingly, the control unit applies calculate computation methods suitable for vector sizes. Thus, in addition to applicable algebraic calculation methods z. B. trigonometric calculation methods for calculating individual components of the respective vectors are used. In the calculation, the control unit incorporates, to the extent necessary, its previously entered substantially fixed values, e.g. B. the respective mass of the controllable rollers 04; 06; 07; 08; 09; 11 and the center distance for each controllable in their contact force roller 04; 06; 07; 08; 09; 11 to its respective adjacent rotary body 12; 13; 14; 16; 17. The result of the calculation can with the display device of the control unit z. For example, like the original values FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 are displayed.

In order in a selected roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 the new value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; To set FN62 of the applied there pressing force, actuates the control unit with at least one of the valves V15; V25; V35; V45; V55; V65 first the fixing device of that roller lock 21, in which the radial force Fn1; Fn2; Fn3; Fn4 at least one actuator 22 is set to the calculated new value, so that in this roller lock 21 mounted controllable roller 04; 06; 07; 08; 09; 11 is radially displaceable. Then, the control unit actuates at least one of the proportional valves EP1; EP2; EP3; EP4 and / or at least one of the valves EP5; EP6, the radial force Fn1; Fn2; Fn3; Fn4 at least one actuator 22 in the affected roller lock 21 to the calculated new value. Thereafter, the control unit again actuates the at least one previously actuated valve V15; V25; V35; V45; V55; V65 to the fixing device of that roller lock 21 in which the radial force Fn1; Fn2; Fn3; Fn4 at least one actuator 22 has been set to the calculated new value, to put in those operating position in which in this roller lock 21 mounted in its contact force controllable roller 04; 06; 07; 08; 09; 11 is no longer radially displaceable. With the new value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 for those in a selected roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; As a result, N62 also produces an altered width of this roller strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62.

The above-described variation of a value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 in a selected roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 exerted contact force can for several controllable in their contact force rollers 04; 06; 07; 08; 09; 11 occur simultaneously or sequentially. For example, the value FN11; FN12; FN21; Fn22; FN31; FN32 of all applicator rollers 04; 06; 07, ie the dampening roller 04 and the inking rollers 06; 07 applied contact forces changed simultaneously. Or it becomes the value FN21; Fn22; FN31; FN32; FN51; FN52; FN61; FN62 of all contact forces, the rollers 06; 07; 09; 11 of the inking unit 02, or the value FN11; FN12; FN41; FN42 of all contact forces, the rollers 04; 08 of the dampening unit 03, or the value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 of the contact forces of all rollers 04; 06; 07; 08; 09; 11 of the printing unit 01 changed simultaneously. Thus, groups of simultaneously variable values FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 are formed. With the control unit, the value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 the contact forces of all to be changed in their respective contact force rollers 04; 06; 07; 08; 09; 11 z. B. an inking unit 02 and / or a dampening unit 03 in a period of less than a minute, preferably in a period of a few seconds, be reset.

It can be provided that each value changed once or even several times FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 of a roller 04; 06; 07; 08; 09; 11 applied contact force z. B. with the control element of the control unit to the standard configuration corresponding value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62, in particular to the target value for the roll strip N11 in the corresponding roll strip; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied contact force, can be reset.

The control unit is z. B. formed as part of a printing press or at least to a printing unit 01 associated control station and thus associated with the printing press or the printing unit 01. Alternatively or additionally, the control unit z. B. as a mobile unit, for. B. as a notebook, which only if a value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 one in a roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 is to be changed, with the controllable device to be operated to carry out this change, d. H. in particular with the relevant proportional valves EP1; EP2; EP3; EP4, the valves EP5; EP6 and the valves V15; V25; V35; V45; V55; V65, is connected.

For making a change in the value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 one in a roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 may be required proof of authorization by performing before the change of the control unit with its control z. B. enter a valid password.

The change of the value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 one in a roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied during the rotation of the roller concerned 04; 06; 07; 08; 09; 11 are performed. If on the lateral surface of the forme cylinder 12 in the axial direction at least one channel with a preferably slot-shaped, in the axial direction of the forme cylinder 12 at least over the width of at least one printing plate continuous opening for receiving at the Formed bevelled becket Einhänbringeln, the change takes place the value FN11; FN21; FN31 in this roll strip N11; N21; N31 applied force when the opening of the channel and the roller strips N11; N21; N31 have no common overlapping surface, so that the roller 04; 06; 07 during the adjustment of the new value of its in this roll strip N11; N21; N31 does not press into the opening of the channel. The in a roll strip N11; N21; N31 applied pressure force is therefore changed by the control unit only at times during which to be adjusted and / or in its contact force to be changed roller 04; 06; 07 on the closed, usually solid trained part of the lateral surface of the forme cylinder 12 and / or on the surface of at least one mounted on the forme cylinder 12 printing form unrolls. During the overrunning of the opening of the channel, the control unit blocks any change in the setting of one in the roller strip N11; N21; N31 applied contact pressure.

To test this condition can on the forme cylinder 12 and / or on the roller 04; 06; 07 a the respective angular position of the forme cylinder 12 and / or the roller 04; 06; 07 detecting sensor, z. As a rotary encoder, be attached, which emits a signal corresponding to the respective angular position signal to the control unit, wherein the control unit this signal as a permission signal for the permissibility of a change in the setting of a roll strip N11; N21; N31 evaluates applied contact pressure. If the above condition is not met or only with difficulty, the forme cylinder 12 together with that roller 04; 06; 07, in their common roller strip N11; N21; N31 is the value FN11; FN21; FN31 is to be changed in the applied pressing force, in rotation, with such a speed that a rolling over of the opening of the channel by the roller 04; 06; 07 during the adjustment of the new value of its in this roll strip N11; N21; N31 applied contact force does not adversely affect because the rollover time is very short and thus outweighs the effect of inertia of the masses involved. Incidentally, the performance of the change of the value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 one in a roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied during the rotation of the affected roller 04; 06; 07; 08; 09; 11 also has the advantage that slip-stick effects are avoided. The change of the value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 one in a roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 applied pressing force is therefore during the rotation of the affected roller 04; 06; 07; 08; 09; 11 and its affected adjacent rotation body 12; 13; 14; 16; 17 at a speed z. B. of at least 3,000 revolutions per hour, preferably at least 5,000 revolutions per hour or more performed. Carrying out the change of the value FN11; FN12; FN21; Fn22; FN31; FN32; FN41; FN42; FN51; FN52; FN61; FN62 one in a roll strip N11; N12; N21; N22; N31; N32; N41; N42; N51; N52; N61; N62 force applied can therefore also be done during the ongoing production of the printing unit 01.
