The manipulation can be via control elements of or interacting with the fields of the screen control device 57 and in the case of a touch-sensitive and / or touchscreen-capable version of the screen 56 possibly directly by interaction with appropriately provided screen areas or in a mixed form by activating the relevant axial section a _j representing field on the screen 56 and manipulation of the setting on the operating device 57 respectively.

A remotely operated means in this sense - in contrast to a single spot on the spot - that the control elements 66 can be set centrally in the same control interface, and not only individually by each decentralized for each of the switching and / or adjusting means along the row of axial sections a _j provided mechanical or electrical control elements.

The control device 46 is at least trained by operators on the control interface via control elements 66 for one or more axial sections aj and / or drying elements 41 _k made positioning commands, z. B. actuated at the actuators actuating pulses, inputs or changes in value, by implementing a control of the affected switching and / or adjusting means 47 _v in a defined manner.

This condition should be met for example at a preferred operating pressure and / or in a distance corresponding to the normal distance, the operating pressure in this case, for example, between 1 and 6 bar, preferably between 2 and 5 bar, in particular at 3.0 bar above ambient pressure. In the case that there is no sharp-edged beam profile in the axial direction, the above-mentioned definition - namely the length of the effective or axial section a _j in the axial direction between the two 50% final values - is applicable for the respective effective width b _j .

In a second embodiment for the formation and arrangement of the independently adjustable axial sections a _j (see, for example, FIG. 10 ) are the execution of the drying elements 41 _k , in particular blowing elements 41 _k , the relative arrangement of the drying elements 41 _k , in particular blowing elements 41 _k to each other and to the surface F of the rotational body 12 ; 13 ; 14 ; 19 ; 23 ; 24 ; 26 ; 27 ; 33 ; 34 ; 36 and / or the present beam angle α formed such that several, preferably all in the direction of printing width staggered adjacent active or axial sections a _j in pairs significantly, ie at least 20%, in particular at least 30%, preferably 40% to 60% of their width b _j with an adjacent axial section a _j - z. B. calculated at least from at least one of the two ends of the axial section a _j ago - overlap. This condition should be met, for example, at a preferred operating pressure in a distance corresponding to the normal distance, wherein the operating pressure, for example, between 1 and 6 bar, preferably between 2 and 5 bar, in particular at 3.0 bar above ambient pressure. In the case that there is no sharp-edged beam profile in the axial direction, the definition mentioned above can also be used for the respective effective width b _j .

In a third embodiment, not shown, for the formation and arrangement of the independently adjustable axial sections a _j are the execution of the drying elements 41 _k , in particular blowing elements 41 _k , the relative arrangement of the drying elements 41 _k , in particular blowing elements 41 _k to each other and to the surface F of the rotational body 12 ; 13 ; 14 ; 19 ; 23 ; 24 ; 26 ; 27 ; 33 ; 34 ; 36 and / or the present beam angle α formed in such a manner and acted upon by a resource, that in a first operating situation, several or all of the adjacent active forces offset in the direction of the printing width or axial sections a _j when a first, z. B. lower of two different operating pressures are mutually spaced or substantially adjoin one another, ie no or at most an overlap of less than 20%, in particular less than 10% of the effective width b _j each other, and in a second operating situation when a second, z. B. higher of the two different operating pressures in pairs significantly, that overlap at least 20%, in particular at least 30%, preferably 40% to 60% of its width b _j with an adjacent axial section a _j . This should be met for example at respective operating pressure in a distance corresponding to the normal distance, wherein the first and the second operating pressure, for example, in each case between 1 and 6 bar, preferably between 2 and 5 bar, with the proviso that the second operating pressure is greater than the first. Again, in the case that in the axial direction no sharp-edged beam profile is present for the respective effective width b _j above definition applicable.

In the second embodiment and arrangement of the independently adjustable axial sections a _j or in the operating situation of the third embodiment and arrangement with significant overlapping, it is possible, during operation, to activate a mutually different selection of one or more of the drying elements 41 _k optionally or at the same time one or more by two adjacent drying elements 41 _k simultaneously treated sections "2 l" and one or more by only one drying element 41 _k treated sections "l" and / or one or more untreated sections "-" on the by the drying device 39 Covered effective width to create and / or train. For illustration are in 11 as an example, the drying elements 41 _k and 41 _{k + 1} activated or their switching and / or adjusting means in the switching state "on", while the drying elements 41 _k-1 (only hinted) and 41 _{k + 2 are} disabled or their switching and / or adjusting means in the switching state "off",

In a first embodiment of the device with respect to the placement of the drying elements 41 _k - Which on all of the above on the arrangement and design of the axial sections a _j and / or on all the above refinements and developments of the drying elements 41 _k can be obtained - the device for adjusting and / or changing the axially extending dampening solution profile is adapted to the drying elements 41 _k and / or the switching and / or adjusting means 47 _{s associated} therewith between - in particular only - two switching states, namely an active ("on") and an inactive ("off") switching state. From the controller 46 For this purpose, each of the drying elements 41 _k and / or the associated switching and / or adjusting means 47 _s via the signal connection 64 can be acted upon by a switching state "on" and a switching state "off" representing signal, wherein one of these two signals by the "zero signal", ie the signal at rest in the signal level or form, may be given.

For example, in view of the associated costs, the switching and / or adjusting means 47 _{s are} preferred here as between at least two switching states, namely between at least one passive state and at least one active state of the relevant drying element 41 _k causing switching state, switchable switching and / or adjusting means 47 _v , Preferably as only between these two switching states "on" and "off" switchable switching and / or adjusting means 47 _v educated. They are z. B. as an electrical on / off switch or in particular as an optional openable and closable fluid valves 47 _v executed, by which, depending on the corresponding switching and / or adjusting means 47 _v present, by the controller A via the control signal S _V assigned switching state, the supply of the working medium, z. B. with a radiation underlying electric power or preferably with a jet S underlying fluid flow, on or off. In this embodiment, the switching and / or adjusting means 47 _v preferably designed as a binary switchable between a switching state "on" and a switching state "off" and / or driven.

A place of drying elements 41 _k or the switching and / or adjusting means 47 _{s associated} therewith-optionally optionally and in addition to an implemented control routine, for example coupled to a zonal dampening solution measurement and / or to a color zone setting-at an above-mentioned operator interface via, for example, above-mentioned control elements 66 and the controller 46 manually by the operator. By operating personnel at the operator interface for one or more axial sections aj and / or drying elements 41 _k Defaults or changes made are then implemented by appropriate control of the affected switching and / or adjusting means 47 _v in a defined manner. Thus, for example, one of the circuitry of the axial sections a _j associated adjusting elements 66 , z. B. the k-th actuator 66 _{k are changed} with respect to its circuit state representing value by the relevant actuator 66 For example, the button in question 66 or the respective button or button pair 66 or the relevant field in the screen mask 69 actuated and / or modified accordingly. In the case of the first embodiment for setting the drying elements 41 _k , namely between only the two switching states "on" and "off", the switching can be done by pressing a button on a real or virtual, generated as a field on the screen button 66 or by a change of a value representing the intended switching state X _k in a specific drying element 41 _k relevant field 66 a screen mask 69 respectively. In the case of binary only to be asked when placing a z. B. only two values X _k , z. B. X _k ∈ {0, 1}, are selected, where here representatively for other types of expressions the value 0 for an inactive and the value 1 is shown (see, eg. 11 ).

In an advantageous embodiment, in which, for example, an above-mentioned central switching and / or adjusting means 48 is provided, in addition to the binary setting of the drying elements 41 _k and / or the switching and / or adjusting means 47 _{s associated} therewith a setting of a level in the operating medium potential in the above sense, for example a setting of the for all or at least several of the same supply line 63 supplied with equipment drying elements 41 _k or switching and / or adjusting means 47 _s pressure levels to be provided.

A site of multiple drying elements 41 _k upstream central switching and / or adjusting means 48 can - optionally optionally and in addition to an implemented, for example, to a zonal dampening and / or to a color zone setting coupled control routine - at an above-mentioned operator interface by pressing an adjusting elements 71 if necessary, the control device 46 manually by the operator. Defaults or changes made by operating personnel on the operator interface for a variable representing the operating medium level and thus the respective beam power in their maximum effect are then achieved by appropriate control of the switching and / or actuating means 48 implemented in a defined manner. For example, to place a z. B. button or button pair 71 trained actuator 71 on the table or on the control panel 57 or a relevant field 71 in a separate or an above-mentioned screen or display mask 54 ; 69 be provided and operable over which the height of the level by pressing a real or virtual button 71 and / or by entering or changing a value representing the level height Z, z. As a percentage of the maximum possible level, in a field 72 , Display and / or input field 72 , the screen mask 54 ; 69 can be changed. (see eg 11 and 12 ).

In a second embodiment of the device with respect to the placement of the drying elements 41 _k - Which on all of the above on the arrangement and design of the axial sections a _j and / or on all the above refinements and developments of the drying elements 41 _k can be obtained - the device for adjusting and / or changing the axially extending dampening medium profile is adapted to the related to a peripheral portion of the cooperating rotating body in an axial section effect, for. As related to a peripheral portion of the co-rotating body effective beam power, not only between the two limit switching states, z. Example, a maximum value corresponding state, which corresponds to the maximum provided for applying beam power, and an inactive state, resulting in a beam power zero at z. B. switched off drying element 41 _k but in addition to be able to spend in one or more further discrete states or in states of an intermediate continuous Stellereichs for the beam power. These are the drying elements 41 _k or the associated switching and / or adjusting means 47 _s with corresponding signals representing these switching states S _V or signal sequences S _V acted upon.

The drying elements associated with the axial sections for removal of the dampening solution 41 _k or the associated switching and / or adjusting means 47 _s are thus - in particular via actuatable by operating elements and a control means connected to the control elements - each individually in the extent of their temporally or area averaged interaction between an inactive operating state, representing a maximum value active operating state and at least one intervening intermediate intermediate active operating state variable.

The realization of the application of the between the limit switching states "on" (= "max") and "off" (= "zero") intermediate values for the o. G. In principle, area-related beam power to be applied can be produced in different ways, for example by varying the size of the area-related beam power (eg the area-related radiant power in the case of electromagnetic radiation or the area-related mass flow in the case of a fluid flow S) or by varying the proportion to be acted upon Time unit or a beaufschlagendem peripheral portion - be accomplished.

Thus, under the above-mentioned temporal averaging for the degree of the action, a mean value of the average value of the averaging over time can be obtained for a given stationary operating state In the case of a continuous and constant application of this value, the value of the application, for example, the per unit time, z. B. per second, applied electromagnetic radiation or preferably applied amount of air, and in the case of a discontinuous, z. B. pulsed exposure to the averaging over a full cycle resulting average value of the action, for example, the applied in the cycle electromagnetic radiation or preferably the amount of air acted upon. For both the continuous and the discontinuous case, this value represents the "beam power" of the electromagnetic or the fluid jet present in the relevant operating state. In a possible alternative embodiment of different types, eg. B. mechanical action of a squeegee or acceptance device, this time-averaged value can be generalized understood in terms of a measure of the time-related impact as "acting". Parallel to this can under the area average a - for a particular steady-state operation - from the averaging over through the dry element 41 _k be treated surface area resulting average value of the action, this value in the case of a continuous and constant application of the value of the application, for example, the per unit area, z. B. per m ² , applied electromagnetic radiation or preferably applied amount of air, and in the case of a discontinuous, z. B. pulsed loading corresponding to the averaging over the treated surface in a full cycle average value of the action, for example, applied to the surface treated in this cycle electromagnetic radiation or preferably applied amount of air corresponds. Both for the continuous and for the discontinuous case can be for the present case, a relative speed between dry element 41 _k and surface to be treated F the time-related and the area-related value for the degree of action with knowledge of the effective width b _j and relative speed into each other.

In a first embodiment, in which, for example, as a switching and / or adjusting means 47 _v og binary switching and / or adjusting means 47 _V application can be applied to one or more intermediate values for the beam power by varying the portion to be acted upon in the considered peripheral portion by clocking the admission, ie by means of a pulsed, also referred to as pulsed beam S. On a peripheral portion of the co-rotating body is by the drying element 41 _k in the respective axial section a _j in a first time interval, a beam S in the switching state "on" and in a second time interval in the switching state "off" no beam S deployed, wherein the time intervals may correspond or deviate from each other. Depending on the ratio of the example adjustable intervals can be z. B. vary on the peripheral portion in the axial section a _j applied beam power.

In the control device 46 For this purpose, a control logic "A", z. B. as electronic circuit "A" and / or as algorithm "A", be implemented by which the desired - set for example by the operator on the control interface - amount of applied for the affected axial section a _j beam power or this radiation power expressing averaged or effective switching state in a correspondingly clocked signal, in particular a correspondingly clocked signal sequence S _V for acting on the relevant drying element 41 _k or the associated switching and / or adjusting means 47 _{s is} processed. In the case of the drying elements designed as blowing elements 41 _k flows, for example, in the operating in the switching state "on" interval with open switching and / or adjusting means 47 _s , z. B. valve 47 _v , the fluid flow S out, while in the operated in the switching state "off" interval no fluid S flows out.

By the control device 46 are thus several or all of the drying elements 41 _k basically individually, ie basically in the clock frequency and / or the phase components between "on" and "off" - different from each other and / or independently, clocked between a switching state "off" and a switching state "on" operated and / or operable. In this case, this timing means no on or off, as it occurs in a change from one to another setting for the effect to be achieved, but for a certain adjustment of the average effect to be achieved to achieve this - ie higher-frequency - in the on-off modulation. By a control device 46 are thus several or all of the drying elements 41 _k in one of the active operating states individually clocked between a switching state "off" and a switching state "on" operable or operated.

A clock frequency for the passage of a cycle between the change in the switching state "on" to the next change to the next switching state "on" can with the machine speed of the printing unit, ie directly or indirectly with the rotational frequency of one or more of the rotary body 12 ; 13 ; 14 ; 19 ; 23 ; 24 ; 26 ; 27 ; 33 ; 34 ; 36 , the cylinder to be inked 13 ; 19 , of the printing unit 11 ; 21 , z. B. with this rotation body 12 ; 13 ; 14 ; 19 ; 23 ; 24 ; 26 ; 27 ; 33 ; 34 ; 36 itself or with a rotationally coupled to this component or drive or with a mechanical or electronic master axis, be correlated. The clock frequency can be z. B. between 0 cycles per revolution of the forme cylinder and 100, or even 500 cycles per revolution of the forme cylinder be variable. In an advantageous development, in particular for cycle numbers of z. B. less than 20 cycles per revolution of the forme cylinder, the respective number of cycles per revolution of the forme cylinder is not selected or set integer.

The phase components can in principle be symmetrical, i. H. 50%: be distributed 50%, but advantageously at least within a range between 30%: 70% and 70%: 30%, preferably even between 20%: 80% and 80%: 20%, based on the ratio of the phase lengths "An ":" To be variable "or varied.

In a second, instead of the first or optionally optionally or in combination with this intended or to be provided, the application takes place with one or more intermediate values for the beam power by varying the thickness of the through the drying element 41 _k delivered on a unit area of the applied surface F related beam power. On a peripheral portion of the co-rotating body is or is by the drying element 41 _k in the relevant axial section a _j then, for example, in an operating situation, a beam S with, for example, a first beam power - z. B. first radiant power to electromagnetic radiation or a fluid jet S with a first mass flow - and in a different mode of operation with respect to the first beam power z. B. higher energy beam power -. B. stronger electromagnetic radiation or a fluid jet with a larger mass flow - acted upon or acted upon. Depending on the set beam power also varies in the axial portion a _j total applied in the respective peripheral portion beam power.

For this purpose, in the case of as blowing elements, for example, as switching and / or adjusting means 47 _v a switching and / or adjusting means which can be brought into more than two discrete, defined switching states 47 _v , preferably a switching and / or adjusting means 47 _v with a continuous control range, provided by the controller with corresponding signals S _V , in particular control signals S _V can be acted upon. In the case of the drying elements designed as blowing elements 41 _k is z. B. as switching and / or adjusting means 47 _v a continuous valve 47 _v , in particular a proportional valve 47 _v intended. In the control device 46 can be a control logic "B", z. B. as electronic circuit "B" and / or algorithm "B", be implemented by which the desired - for example, set by the operator on the user interface - set for the affected axial section A _j switching state in the associated control signal S _V for acting on the relevant drying element 41 _k or the associated switching and / or adjusting means 47 _{s is} processed.

In an embodiment which is advantageous for both embodiments, in which, for example, an above-mentioned central switching and / or adjusting means 48 is provided, in addition to - for example, clocked or clocked and / or varied in strength or variable - points of the drying elements 41 _k and / or the switching and / or adjusting means 47 _{s associated} therewith a setting of a level in the operating medium potential in the above sense, for example a setting of the for all or at least several of the same supply line 63 supplied with equipment drying elements 41 _k or switching and / or adjusting means 47 _s present on the input pressure levels P _E be provided.

For both mentioned embodiments, a setting of the drying elements 41 _k or the switching and / or adjusting means 47 _{s associated} therewith-optionally optionally and in addition to an implemented control routine, for example coupled to a zonal dampening solution measurement and / or to a color zone setting-at an above-mentioned operator interface via, for example, above-mentioned control elements 66 and the controller 46 manually by the operator. By operating personnel at the operator interface for one or more axial sections aj and / or drying elements 41 _k Defaults or changes made are then implemented by appropriate control of the affected switching and / or adjusting means 47 _v in a defined manner. Thus, for example, one of the circuitry of the axial sections a _j associated adjusting elements 66 , z. B. the k-th actuator 66 _{k are changed} with respect to its circuit state representing value by the relevant actuator 66 For example, the button in question 66 or the relevant pair of buttons 66 or the relevant field in the screen mask 69 correspondingly long actuated and / or modified in value. In the case of the second embodiment for setting the drying elements 41 _k , namely between more than the two switching states "on" and "off", the setting can be made by a longer or by a corresponding multiple keystrokes on a real or virtual, generated as a field on the screen button 66 or by changing a value Y _k representing the intended switching state in a specific drying element 41 _k concerned field 66 a screen mask 69 respectively. In this more than merely binary case to be asked when placing a z. B. more than two values y _k comprehensive, more or less finely graded stock of values, z. B. in percentage steps or, for example, in 10% steps (Y _k ∈ {0%, 10%, 20% ... 100%}, are selected, wherein the selected representation is representative of different scale divisions and / or sizes (see eg 12 ).

In addition to or independent of the described possibility of influencing the dampening solution profile by the operator via a place on the relevant user interface can also be on the switching and / or adjusting means 47 _v acting, based on a zonal measurement of the dampening solution guide and / or a control measurement of the printing result control loop and / or a coupling of the setting in the axial sections a _j with an adjustment of inking zones z _i Control and / or regulation process be provided with appropriate control or regulation means.
