The printing works 04 wise printing cylinder 06 ; 07 on which are to be set in pairs in print-on.

The methods and / or devices shown below can also be used on printing units 04 be applied advantageous in which the substrate 02 not web-shaped, but is designed as a bow.

It is essential now that one or more of the printing cylinder 06 ; 07 - At least for the period of setting a wegbegrenzenden stop - force controlled to each other are adjustable. Thus, the Anstelllage is found, which is based directly on the relevant parameters for printing "force" or "Anstelldruck" and is not determined by a detour, such as measuring and setting a width of the impression strip.

The storage and the actuators for this operating principle can be configured in many ways and will be described in more detail below. Likewise, this principle in printing works 04 or printing units 01 Be used in a variety of configurations, in the use of the functional principle based on an advantageous embodiment of a printing unit 01 or advantageous embodiment of a printing unit 04 is described.

The printing unit 01 In the present example, there are several (in the present case four) vertically stacked double printing units 03 for two-sided printing in rubber-against-rubber operation. The double printing units 03 - shown here in the form of bridge or n-printing - are each by two printing units 04 formed, each one as a transfer cylinder 06 and one as a form cylinder 07 trained cylinder 06 ; 07 , z. B. printing cylinder 06 ; 07 , as well as one inking unit each 08 and in the case of wet offset printing additionally a dampening unit 09 exhibit. In each case between the two transfer cylinders 06 becomes in anstelllage a (double) pressure point 05 educated. The components mentioned are only on the top double printing unit 03 of the 1 referred to, wherein the stacked (double) printing units 03 ; 04 However, essentially - especially in the embodiment of relevant to the invention - are identical. The double printing units 03 can - as well as the below-described advantageous feature of the linear arrangement - just as well contrary to the representation in 1 as to be upwardly opening U unit executed.

As in 2 and 3 the printing unit can be described 01 in an advantageous embodiments z. B. in the middle, ie in the region of the double pressure point (s) 05 , or as in 4 shown between form cylinder (s) 07 and inking unit (s) 08 be executed operationally divisible. Additionally are in 2 and 3 two supply systems explained in more detail below 75.1 ; 75.2 indicated for pressure medium.

Like also in 2 and 4 as an example, the inking can 08 (and possibly dampeners 09 ) as already multi-roll modules with their own frame 16 or a frame construction 16 trained and as pre-assembled modules in the printing unit 01 be formed usable. As explained in more detail below, the cylinders 06 ; 07 associated with them storage units 14 as preassembled or preassembled cylinder units 17 be educated. In an advantageous embodiment, the axes of rotation of the printing cylinder 06 ; 07 a printing unit 04 be executed lying in pressure-An substantially in a common plane E lying. The plane E takes z. B. an angle between 76 ° and 87 °, in particular between 80 ° and 85 ° to the plane of the inlet web.

In the following 2 and 3 is an advantageous embodiment of the printing unit 01 shown in the region of their double pressure point (s) 05 , operational, ie designed for setup and maintenance purposes (in contrast to disassembly or disassembly), divisible. The two separable parts are here with partial pressure units 01.1 and 01.2 designated.

These are the printing cylinder 06 ; 07 the several (four) stacked double printing units 03 rotatable in or on a right and a left frame or wall section 11 ; 12 , z. B. side frame 11 ; 12 stored in the way that the two printing cylinder 06 ; 07 of a same printing unit 04 the same frame or wall section 11 ; 12 assigned. Preferably, the printing cylinder 06 ; 07 several, especially all the train 02 printing units printed on the same side 04 on the same frame or wall section 11 ; 12 stored. The printing cylinder 06 ; 07 can in principle only one side, ie flying on only one end frame sections 11 be stored. Preferably, however, each partial pressure unit 01.1 ; 01.2 two frontal to the cylinders 06 ; 07 arranged frame sections 11 ; 12 intended. The two separable partial pressure units 01.1 and 01.2 have the respective frame sections 11 ; 12 and printing works 04 (Printing cylinders 06 ; 07 and inking 08 ) on.

The partial printing units 01.1 ; 01.2 are along a direction perpendicular to the axis of rotation of the cylinders 06 ; 07 moving towards or away from each other, preferably by one of both spatially fixed (here partial pressure unit 01.1 ), ie, for example, on a floor 13 the Druckereiraumes, a space-fixed support 13 , a mounting plate 13 or a mounting frame 13 for the printing unit 01 stationary, and the other (here partial pressure unit 01.2 ) movable in relation to the ground 13 or carrier 13 or mounting plate 13 or mounting frame 13 (in the following carrier 13 ) is stored.

For this purpose, the outer frame sections 12 in mutually corresponding, not shown bearing elements of the frame portion 12 and the vehicle 13 , z. B. together a linear guide 15 forming, stored. These can be designed as running in rails rollers or as a sliding or rolling body mounted mutually associated linear guide elements.

Preferably, the wall sections 11 ; 12 designed such that in its operating position A ( 2 ) are formed on their mutually facing side in pairs substantially complementary to each other form and together at their parting lines or lines of collision nevertheless form a substantially closed side front.

3 shows a maintenance position B of the printing unit 01 (without the in 2 indicated storage units 14 ), wherein the relative position of the partial pressure units 01.1 ; 01.2 each other by moving the frame sections 12 is effected. The relative position can in principle also be achieved in another embodiment, by both partial pressure units 01.1 ; 01.2 or their frame sections 11 ; 12 are movably mounted.

In a variant ( 4 ) of a separable printing unit 01 is the side frame 11 ; 12 not divisible in the way that the printing cylinder 06 ; 07 at the pressure point 05 be separated, but it is the printing cylinder 06 ; 07 in or on a common side frame 11 ; 12 stored undivided, while on both sides of the inking 08 receiving wall sections 18 in an operating position A (not shown) or a maintenance position B (shown) can be brought. The division takes place here between form cylinder 07 and color and possibly dampening unit 08 . 09 ,

Form and transfer cylinder 07 ; 06 can in an advantageous format design with a bale width of at least four, z. B. four or for particularly high product output six, juxtaposed standing printed pages in newspaper format, especially in broadsheet format, be formed. So can a double wide track 02 next to each other with four or a triple wide track 02 printed side by side with six newspaper pages, and the forme cylinder 07 corresponding to four or six printing plates, in particular with their ends aligned with each other, are occupied side by side. In a first format design, the cylinders 06 ; 07 a circumference which essentially corresponds to two printed pages arranged one behind the other in a newspaper format, in particular in broadsheet format.

In the versions of the printing unit 01 with form cylinders 07 This double-sized format (two newspaper pages circumferentially one after the other) advantageously has two channels circumferentially offset by 180 ° from each other for receiving the printing plates, which are preferably formed continuously over the entire effective length of the bale. The form cylinder 07 can then be equipped with four or six printing forms side by side and two printing plates in a row.

The transfer cylinder 06 has a double large format (two newspaper pages in a row behind each other) in one embodiment z. B. only one channel for receiving one or more juxtaposed blankets, which is preferably formed continuously over the entire effective bale length. The transfer cylinder 06 can then be equipped with a continuous over the bale length and over substantially the full extent reaching or with two or three over substantially the full extent reaching blankets juxtaposed.

In another version of the double-sized transfer cylinder 06 this two or three blankets may have side by side, wherein the respective adjacent to each other are offset by 180 ° in the circumferential direction. These staggered blankets can be held in two or three channel sections, which also in the longitudinal direction of the cylinder 06 side by side, the adjacent channel sections in the circumferential direction, however, are mutually offset by 180 °.

In another version, the cylinders 06 ; 07 However, even with a simple scope - a print page in particular newspaper page in the circumferential direction - be formed. It can be the transfer cylinder 06 also with double circumference and the form cylinder 07 be formed with a simple scope. In printing units 04 for commercial printing, the cylinders can 06 ; 07 be formed with circumferences, which corresponds to four lying tabloid pages.

Basically, the inking unit 08 be formed in different ways. So it can be like in 1 exemplified z. B. as einzughiges roller inking 08 z. B. with two Reibzylindern (eg., From the newspaper printing) or as exemplified in 2 and 3 shown as short ink works 08 be formed using a cup or scouring raster roller. In unillustrated embodiment, it can also be used as a roller inking unit 08 with two color trains and z. B. three friction cylinders (eg., From the commercial printing) to be executed.

In the case of dry offset is per printing unit 04 an inking unit 08 , but no dampening 09 intended. In wet offset is by the dampening 09 , strictly separated from the inking unit 08 or connected in parallel via a bridge roller with the inking unit 08 , Dampening solution supplied.

The dampening unit 09 can as dampening 09 with at least three rollers (in 1 represented). Preferably, the dampening unit 09 as so-called contactless dampening unit 09 , in particular spray dampening 09 , executed. Like also in 2 and 3 indicated, the printing units 04 in each case a handling device 19 have to support the printing form change. In a preferred embodiment, the handling device 19 as at least semi-automatic or even fully automatic printing form changer 19 executed.

Regardless of the below-described, advantageous embodiment of the storage as a storage unit 14 as well as their special design and arrangement, there is a pressure-on bodies of printing cylinders 06 ; 07 or at least a pressure-on points in the context of presetting a wegbegrenzenden stop by means of at least one actuator 43 , in particular by a force-controlled or via a force defined actuator 43 , By means of which for employment a defined or definable force F in pressure-on direction to the cylinder 06 ; 07 or whose pin is engageable. The decisive for the color transfer and thus the print quality, inter alia, line force in the Nippstellen is therefore not by an indirect parameter such. B. a measured impression strip, but by the balance of forces between the force F and between the cylinders 06 ; 07 resulting line force F _L and the resulting equilibrium defined.

For basic adjustment of a system, it is therefore provided in an advantageous embodiment that at least one cylinder 06 ( 07 ) during a period when setting - without effective Wegbegrenzung to the pressure point - only force controlled to the adjacent cylinder 06 ( 07 ) is adjustable. It is advantageous at least during a certain period of the adjustment process at the pressure point 05 involved cylinder 06 in a defined position, advantageously in the balance of forces weight found Anstelllage, fixable or at least in the direction of the pressure point 05 wegbegrenzbar.

In an advantageous embodiment of the printing unit 01 is provided, the cylinder 06 ; 07 in storage units 14 on the side frames 11 ; 12 rotatable to store, which the flight of the side frames 11 ; 12 do not penetrate and / or the cylinders 06 ; 07 with her bale 26 ; 27 including their cones 21 ; 22 a length L06; Have L07, which is less than or equal to a clear width L between the printing cylinder 06 ; 07 to both end faces supporting side frames 11 ; 12 ( 5 ). At the printing cylinders 06 ; 07 to both end faces supporting side frames 11 ; 12 it is preferably not laterally so open side frames, so that the cylinder 06 ; 07 axially removed, but to side frames 11 ; 12 which in the axial direction at least partially overlap with the end face of the mounted cylinder 06 ; 07 have, ie the cylinder 06 ; 07 , in particular its bearing (see below), is frontally through the two side frames 11 ; 12 at least partially framed.

Preferably, all four printing cylinder 06 ; 07 (but at least three) own storage unit 14 on, in which the on / off mechanism is already integrated. It can also work for three of the four cylinders 06 ; 07 the arrival / Abstellmechanismus having bearing units 14 and for the fourth storage units 14 be provided without on / off mechanism.

6 and 7 show a preferably based on linear trajectories bearing unit 14 in schematic longitudinal and cross section. The bearing unit which integrates the on / off mechanism 14 points next to a warehouse 31 , z. B. radial bearings 31 , For example, a cylindrical roller bearing 31 , for rotational storage of the cylinder 06 ; 07 bearing means 32 ; 33 for a radial movement of the cylinder 06 ; 07 - for pressure on or pressure off - on. For this purpose, the storage unit 14 (after mounting the bearing unit 14 fixed to the frame) carrier-resistant bearing elements 32 as well as against these movable bearing elements 33 on. The carrier-fixed and movable bearing elements 32 ; 33 are as cooperating linear elements 32 ; 33 and together with corresponding sliding surfaces or intermediate rolling elements as a whole linear bearing 29 educated. The linear elements 32 ; 33 in pairs take a radial bearing 31 receiving storage block 34 , z. B. slide 34 between themselves. bearing block 34 and the movable bearing elements 33 can also be made in one piece. The carrier-fixed bearing elements 32 are on a carrier 37 arranged, which in total with the side frame 11 ; 12 is connected or is. The carrier 37 is for example as a carrier plate 37 executed, which, for example, at least on a drive side a recess 38 for the penetration of a shaft 39 , z. B. drive shaft 39 one in 7 not shown pin 21 ; 22 a cylinder 06 ; 07 having. Also the frame wall 11 ; 12 on the drive side preferably has a recess or an opening for a drive shaft 39 on. On the opposite side of the drive side does not necessarily have a recess 38 or a recess in the side frame 12 ; 11 be provided.

Preferably, a length of the linear bearing 29 , In particular, at least one length of the frame-fixed in the assembled state bearing means 32 of the linear bearing 29 , considered in the direction of S direction smaller than a diameter of the associated printing cylinder 06 ; 07 ,

The coupling of the cylinder 06 ; 07 or the storage block 34 on a drive side of the printing unit 01 to a drive, for. B. directly to a drive motor and / or a drive train or gearbox, as in 6 for example, shown on the shaft 39 , which at the end near the cylinder one end of the pin 21 ; 22 includes and for example via a clamping device 24 with the pin 21 ; 22 torsionally rigid is connected. The clamping device 24 is here for example as z. T. slotted hollow shaft end formed, which the journal end (pin 21 ; 22 ) and is to be pulled together by means of a screw in such a way that a frictional rotationally fixed connection between the journal end (pin 21 ; 22 ) and hollow shaft inner surface can be produced. The coupling can also in other ways, for. B. in the circumferential direction having a positive connection, be executed. The wave 39 is through a recess in the side frame 11 ; 12 which is sufficiently large for the movement of the shaft 39 together with the storage block 34 is measured and which z. B. is formed in the manner of a slot. As a protection against dirt, a cover 28 be provided with a slot covering the collar, wel cher z. B. with the bearing block 34 but not with the wave 39 connected is.

To the cylinder-distal end of the shaft 39 is like in 6 illustrated one of possibly more serially arranged coupling 40 , in particular multi-plate clutch 40 , by a non-rotatable connection 36 , z. B. a clamping element 36 , can be coupled. In another, not shown embodiment is directly a drive motor or directly a gearbox with drive motor without angle and / or offset compensating coupling to the shaft 39 coupled. In this embodiment, the drive motor z. B. not fixed to the frame, but arranged cylinder-tight and is connected to the cylinder 06 ; 07 moved.

The training of linear bearings 29 in such a way that the cooperating bearing elements 32 ; 33 both on the assembly storage unit 14 - and not a part of the side frame 11 ; 12 the printing unit 01 - Are provided, allows pre-assembly and pre-adjustment or adjustment of the bearing voltage. The advantageous arrangement of the two the bearing block 34 encompassing linear bearings 29 allows a backlash-free adjustment, as the two linear bearings 29 are opposed in such a way that the bearing preload and the bearing forces an essential component in a direction perpendicular to the axis of rotation of the cylinder 06 ; 07 learn or record. The linear bearings 29 are thus adjustable in the direction to which it is at play-free positions of the cylinder 06 ; 07 also arrives.

In the 6 and 7 recognizable linear bearings 29 ( 32 . 33 ) thus each have pairs of corresponding, cooperating bearing means 32 and 33 or their guide surfaces or active surfaces, as sliding surfaces (not shown) formed or arranged therebetween rolling elements 23 , on. As in 15 shown, in a preferred embodiment, at least one of the two, advantageous both linear bearings 29 a storage unit 14 executed such that the two corresponding bearing means 32 and 33 in each case at least two guide surfaces 32.1 ; 32.2 ; 33.1 ; 33.2 have, which lie in two mutually inclined planes. The two guide surfaces 32.1 ; 32.2 ; 33.1 ; 33.2 (or their planes E1, E2) of the same storage means 32 ; 33 are z. B. V-shaped to each other, for. B. with an intermediate angle between 30 to 60 °, in particular between 40 and 50 °, inclined. The two guide surfaces 33.1 ; 33.2 ; 32.1 ; 32.2 of the cooperating bearing means 33 ; 32 are complementary in shape. At least one of the two pairings of cooperating guide surfaces 32.1 ; 32.2 ; 33.1 ; 33.2 is parallel to a plane E1, which has a component not equal to zero in the radial direction of the cylinder axis and thereby the degree of freedom of movement in a purely axial direction of the cylinder 06 ; 07 in derogation. Preferably, both pairings lie to planes E1; E2, both having a non-zero component in the radial direction of the cylinder axis, but in reverse tilt against the cylinder axis and thereby the degree of freedom of movement in both axial directions of the cylinder 06 ; 07 prevention. A section line of the two planes E1; E2 is parallel to the direction S

Is, as in 6 to recognize the storage block 34 between the two, two pairs of co-operating guide surfaces 32.1 . 33.1 and 32.2 ; 33.2 having linear bearings 29 bordered, in particular biased with a bias, so the bearing block 34 only a single degree of freedom of movement along the direction of adjustment S on.

The inclined active or guide surfaces 32.1 ; 32.2 ; 33.1 ; 33.2 are arranged so that they a relative movement of the bearing parts of the linear bearing 29 in the axial direction of the cylinder 06 ; 07 counteract, ie the camp is "tied off" in the axial direction.

Preferably, the linear bearings 29 both a cylinder 06 ; 07 frontally assigned storage units 14 two mutually arranged pairs of cooperating guide surfaces 32.1 ; 32.2 ; 33.1 ; 33.2 on. In this case, however, advantageously has at least one of the two radial bearings 31 the two storage units 14 a slight bearing clearance Δ31 in the axial direction.

In 6 and 15 have the guide surfaces 32.1 ; 32.2 the frame-fixed storage means 32 the linear guide 29 in the cone 21 ; 22 facing half space. The frame-fixed storage means 32 here enclose the storage block arranged between them 34 , The frame-fixed guide surfaces 32.1 ; 32.2 the two linear bearings 29 thus partially cover the guide surfaces 33.1 ; 33.2 of the storage block 34 with respect to an axial direction of the cylinder 06 ; 07 ,

For correct placement of the storage units 14 or cylinder units 17 including storage unit 14 , can installation aids 51 , z. B. dowel pins 51 in the side frame 11 ; 12 be provided, to which the storage unit 14 the fully assembled cylinder unit 17 is aligned before passing through releasable holding means 53 , z. B. screws 53 , or even cohesively by welding with the side frame 11 ; 12 get connected. For those already before insertion into the printing unit 01 to be made and / or readjusted after insertion adjustment of the bearing preload in the linear bearings 29 can appropriate means 54 , z. B. clamping screws 54 be provided ( 6 ). Preferably, the storage unit 14 - At least to the cylinder side - through a cover 57 weitge protected against contamination or even encapsulated executed as a unit.

In 6 is schematically the cylinder 06 ; 07 with cones 21 ; 22 and a preassembled storage unit 14 characterized. This assembly can thus be preassembled between the side frames 11 ; 12 the printing unit 01 easy to install and attached to designated locations. Preferably for a modular design are the storage units 14 for forming and transfer cylinders 07 ; 06 - if necessary, except for the permitted operational size of the travel - identical design. The pre-assembled design allows the effective inner surface of the radial bearing 31 and the outer effective lateral surface of the pin 21 ; 22 be cylindrical instead of tapered, as both the mounting of the bearing unit 14 on the cone 21 ; 22 as well as the setting of the bearing clearance outside the printing unit 01 can be done. The storage unit 14 can be shrunk, for example.

The assembly unit which can be mounted as a whole (storage unit 14 ) Is advantageous in the manner of an optionally partially open housing of z. B. the carrier 37 , and / or z. B. a frame (in 7 z. B. the four the storage unit 14 to all four sides outwardly bounding side members 92 ; 93 ; 94 ; 96 , z. B. side plates 92 ; 93 ; 94 ; 96 ) and / or z. B. the cover 57 ( 6 ). Within this housing or this frame are the radial bearing 31 bearing block 34 , the linear guides 29 and in an advantageous embodiment, for. B. the actuator 43 or the actuators 43 accommodated.

The frame-fixed bearing elements 32 are arranged substantially parallel to each other and define a direction of adjustment ( 7 ).

Pressure on is done by moving the bearing block 34 towards the pressure point by means of a by at least one actuator 43 on the storage block 34 applied force F, in particular by a force-controlled or via a force defined actuator 43 , By means of which for employment a defined or definable force F in pressure-on direction to the bearing block 34 can be brought ( 7 ). The decisive for the color transfer and thus the print quality, among other line force in the Nippstellen is therefore not by a travel, but by the balance of power between the force F and between the cylinders 06 ; 07 resulting line force F _L and the resulting equilibrium defined. In a first, not specifically illustrated embodiment are cylinders 06 ; 07 in pairs put together by the bearing block 34 with the corresponding adjusted force F over the actuator (s) 43 is charged. If several (eg three or four) are adjacent to one another in direct succession, each cylinder interacting in pairs 06 ; 07 executed without a possibility for fixing or limiting the travel S with a purely force-dependent adjustment mechanism, so it is indeed a. With respect to the required pressures (line forces) set system off and subsequently correct again, make a basic setting is due to the z. T. overlapping reactions difficult.

For basic adjustment of a system (with corresponding elevators, etc.), it is therefore provided in an advantageous embodiment that at least the two middle of the four cylinders 06 In other words, at least all of the two outer cylinders 07 different cylinders 06 at least during a period when setting in a defined position, advantageously in the Anstelllage found by the balance of forces, fixed or at least wegbegrenzbar.

Particularly advantageous is an embodiment, wherein the bearing block 34 - Even during operation - at least in one direction away from the pressure point against a force, eg. B. spring force, in particular a definable force, is movably mounted. This will - in contrast to pure Wegbegrenzung - on the one hand, a maximum line force when acting together cylinder 06 ; 07 defined, and on the other hand, a yield, for example, in a web break with subsequent winder on the cylinder 06 ; 07 , allows.

To one of the pressure point 05 facing side, the storage unit 14 - At least during the setting process - a portable stop 41 on, which the travel to the pressure point 05 limited. The stop 41 is locatable in such a way that the stop surface effective as a stop 44 along the direction of adjustment is variable at least in one area. It is thus in an advantageous embodiment, an adjusting device (adjustable stop 41 ) provided by means of which the position of a pressure near the end position of the bearing block 34 is adjustable. For Wegbegrenzung / adjustment serves z. B. a wedge drive described below. Placing the stop 41 can always be used manually or via an actuator ( 46 , see below) 46 respectively. Next is an advantageous embodiment in 6 and 7 not shown holding or clamping means provided by means of which the stop 41 set in the desired location. Next is at least one spring-acting element 42 , z. B. spring element 42 , provided, which on the storage block 34 a force F _R from the stop 41 in one direction from the way. Ie. the spring element 42 causes a pressure-off in the event that the bearing block 34 is not prevented from moving in any other way. Pressing is done by means of motion conditions of the storage block 34 towards the stop 41 by at least one actor 43 , In particular a force-controlled actuator 43 , By means of which for employment either a defined or definable force F in pressure-on direction to the bearing block 34 can be brought. Is this force F greater than the restoring force F _{R of} the spring elements 42 , so takes place with appropriate spatial training a hiring of the cylinder 06 ; 07 to the adjacent cylinder 06 ; 07 and / or hiring the storage block 34 to the stop 41 ,

Ideally, the applied force F, the restoring force F _R and the position of the stop 41 chosen so that between stop 41 and the abutment surface of the bearing block 34 no significant force .DELTA.F is transmitted in the set position, for example, | ΔF | <0.1 · (F - F _R ), in particular | ΔF | <0.05 * (F - F _R ), ideally | ΔF | ≈ 0. In this case, the contact force between the cylinders 06 ; 07 much above that by the actor 43 applied force F determined. The decisive for the color transfer and thus the print quality, among other things, line force in the Nippstellen is therefore not primarily by a travel, but with quasi-free stop 41 defined by the force F and the resulting equilibrium. Basically, after finding the basic setting with the appropriate forces F would be a removal of the stop 41 or a corresponding, effective only during the basic setting fixation conceivable.

The actor 43 can basically as any, a defined force F applying actuator 43 be executed. The actuator is advantageous 43 as actuatable by pressure medium actuating means 43 , in particular as a piston movable by a fluid 43 executed. Advantageous in terms of possible tilting is the arrangement of several, here two, such actuators 43 , As fluid preferably comes because of their incompressibility a liquid, for. As oil or water, used. In another embodiment, the actuator 43 Also as a piezo (piezoelectric force application) or as a magnet (magnetic force application), in particular electromagnet, be formed.

To operate here as a hydraulic piston 43 executed actuators 43 either inside or outside of the storage unit 14 a controllable valve 56 intended. This is performed, for example, electronically controlled and provides the hydraulic piston 43 in a position without pressure or at least to a lower pressure level, while in another position of the force F conditional pressure P is applied. In addition, a non-designated leakage line is provided here for safety.

In order to avoid excessive stopping / stopping distances and still to secure track winders, it can be found on the side of the bearing block away from the pressure side 34 a Wegbegrenzung by a mobile, force-limited stop 49 as overload protection 49 , z. B. spring element 49 be provided, which in the operational pressure-Ab, ie the piston 43 are relieved and / or retracted, although as a stop 49 for the storage block 34 serve in pressure-off position, in the case of a web winder or other excessive forces from the pressure point 05 but gives in and releases a larger path. A spring force of this overload protection 49 is therefore chosen larger than the sum of the forces from the spring elements 42 , When operational on / off is therefore only a very short travel, z. B. only 1 to 3 mm, providable.

The stop 41 is in the illustrated embodiment ( 7 ) as transversely to the direction of adjustment S movable wedge 41 executed, wherein when moving the same position of the respective effective stop surface 44 varies along the direction of adjustment S. The wedge 41 is supported, for example, on a carrier-resistant stop 58 from. The carrier-proof stop 58 is here z. B. by a side support 92 the storage unit 14 educated.

The one here as a wedge 41 executed stop 41 is by an actor 46 , For example, a pressure medium actuatable actuating means 46 such as a pressure medium actuated piston 46 in a working cylinder with (double-acting) piston via a z. B. as a piston rod 47 executed transmission element 47 or by an electric motor via a transmission element designed as a threaded spindle 47 , movable. This actor 46 may be either in both directions effective or, as shown here, designed as a one-way actuator, which when activated against a return spring 48 is working. The force of the return spring 48 is for the above reasons (largely force-free stop 41 ) so weak that the wedge 41 is kept in its correct position only against gravity or vibration forces.

Basically, the stop 41 also in another way (eg as plunger adjustable and fixable to the adjusting direction, etc.) in such a way that it has a stop surface that can be varied in the adjusting direction S and, at least during the setting process, can be fixed 44 for the movement of the storage block 34 in the direction of the pressure point 05 forms. In a non-illustrated embodiment, a place of the stop takes place 41 For example, directly parallel to the direction of adjustment S by a drive means, for example, a pressure medium actuated cylinder with (double-acting) piston or an electric motor.

8th shows as a double printing unit 03 executed printing unit 03 schematically per cylinder 06 ; 07 one on the side frame 11 arranged warehouse Ness 14 , In an advantageous embodiment, shown here form the centers of rotation of the cylinder in pressure-on position 06 ; 07 an imaginary connecting line or plane E (hereinafter referred to as "linear double printing unit"). Preferably, the plane E and the incoming or outgoing path are closed 02 a deviating from 52 ° internal angle α between 36 and 49 °, in particular from 80 to 48 °. The storage unit 14 the transfer cylinder 06 , in particular all cylinders 06 ; 07 , are in the assembled state in the in 8th illustrated embodiment of the side frame 11 arranged such that their adjusting directions S - z. B. reasons of a force-defined pressure-on setting (see below) - with the connection plane E a maximum angle of 15 ° includes, z. B. an acute angle β of about 2 ° to 15 °, in particular 4 to 10 ° form each other. Particularly advantageous in terms of assembly, this arrangement, when the adjustment direction S horizontal and the web 02 is substantially vertical.

In a modified version ( 1 ) of an angular (n or u printing unit 03 ) arranged double printing unit 03 is below the level E 'the connection plane of the pressure point 05 forming cylinder 06 and under plane E '', the connection plane between the forming and transfer cylinders 07 ; 06 be understood, and the above to the angle β in the direction of adjustment S at least one of the pressure point 05 forming cylinders 06 or the form cylinder 07 and the plane E 'or E''are related.

One of the bruise 05 forming cylinder 06 Can also be stationary and operationally inoperable (but possibly adjustable) in the side frame 11 ; 12 be arranged while the other along the adjustment direction S, is movably mounted.

A for switching on / off operational travel along the direction of adjustment S between pressure-off and pressure-on position is z. B. the transfer cylinder 06 at 0.5 to 3 mm, in particular at 0.5 to 1.5 mm, and the forme cylinder 07 at 1 to 5 mm, especially 1 to 3 mm.

For execution as a linear double printing unit 03 is the plane E against the plane of the incoming and outgoing rail 02 z. B. an angle α by 75 ° to 88 ° or 92 to 105 °, preferably by α 80 to 86 ° or 96 to 100 °, each on one side of the web (or 96 to 100 ° or α 80 to 86 ° on the other side of the track) inclined.

In one in another, in 9 illustrated embodiment are the storage units 14 the transfer cylinder 06 , in particular all cylinders 06 ; 07 , when mounted on the side frame 11 arranged such that their adjusting directions S coincide with the connecting plane E, ie form an acute angle β of about 0 °. All adjustment directions S coincide therewith and are not spaced apart.

Regardless of the in 8th and 9 shown slope of the travel paths to the plane E or E 'or E''(small tilt or not) is the schematic example of 10 below, an advantageous procedure for adjusting the cylinder 06 ; 07 (here to distinguish between left and right printing unit with the additions "1" and "2") or their pressure-on position shown:
First, a first, the pressure point 05 with defining cylinders 06.1 , z. B. transfer cylinder 06.1 in its position in pressure on position (ie actuators 43 are active) within the printing unit 01 and to the train 02 by placing the stops 41 (on both front sides) aligned. This can, as indicated here, by an example here as manually operable actuator 46 (Adjusting screw). Here, a pressure point defining so-called. "0-position" is determined.

Subsequently, when the stop is released 41 of the associated forme cylinder 07.1 ie the stop 41 was z. B. previously removed by pulling up, and still activated pressure-on position of the transfer cylinder 06.1 , ie activated actuators 43 the transfer cylinder 06.1 , for the pressure on position between form and transfer cylinder 07.1 ; 06.1 desired force F acted upon. This is done here by acting on the actuators 43 of the forme cylinder 07.1 with the desired contact pressure P. Is on the storage unit 14 of the first forme cylinder 07.1 also an adjustable stop 41 provided, in a first variant already this attack 41 now essentially force-free in contact with the corresponding stop surface of the bearing block 34 on the first form cylinder 07.1 to be brought.

When the print on position is activated (ie, the force applied to the pressure point 05 ) of the first two cylinders 06.1 ; 07.1 and pressure-down of the second forme cylinder 07.2 will, during or after the stop 41 of the third cylinder 06.2 is released, the second transfer cylinder 06.2 or its storage block 34 with the desired force (pressure P) applied to the pressure-on position, and upon reaching the equilibrium whose stop 41 essentially force-free in contact with the corresponding stop surface of the bearing block 34 brought. In this context, before, during or after, if not already done in the above variant, the stop 41 of the first forme cylinder 07.1 in contact with the assigned storage block 41 to be brought.

In a final step is - at free or previously released stop 41 - the second form cylinder 07.2 or its storage block 34 brought in pressure-on, while also the associated transfer cylinder 06.2 Also located in print-on. After reaching stationarity - if an attack 41 provided there - also on the second form cylinder 07.2 this stop 41 essentially force-free in contact with the corresponding stop surface of the bearing block 34 spent.

In this way, an optimally tuned for the printing process adjustment of the cylinder 06 ; 07 of the double printing unit 03 he follows.

In 11 is an embodiment of an interconnection of a pressure medium supply - suitable for implementing the above-mentioned procedure - shown. An outwardly open or closed fluid reservoir 61 is at a pressure level of a pressure P _L (eg, ambient pressure), which is lower than one of the restoring force F _{R of} the spring elements 42 a storage unit 14 corresponding pressure. The pressure medium (fluid) is passed through a compressor 62 , z. As a pump or turbine, compressed to a pressure level P _H or a pressure P _H , which corresponds to at least the pressure level P or pressure P required for the contact force F. In order to minimize pressure fluctuations due to removal of pressure medium, compressed fluid can advantageously be compressed in an accumulator to the pressure P _H 63 be held up. From the high pressure level P _H having pressure medium branch is via an actuator 64 , in particular an adjustable pressure reducer 64 , a supply route 66 depressed, the pressure level P through the pressure reducer 64 to the pressure level P suitable for the pressure on position and preselected pressure P (corresponding force F, possibly taking into account the restoring force F _R and possibly force .DELTA.F) is set or adjustable.

In 11 are dashed lines required for the pressure medium supply units fluid reservoir 61 , Compressor 62 , Pressure accumulator 63 and adjustable pressure reducer 64 to a supply system 75 summarized. The valves 56 Here are close to the cylinder outside the supply system 75 but could also be integrated into it centrally. The fluid reservoir 61 could also be outside the supply system 75 centrally available for several supply systems 75 be available together.

Adjusting the pressure reducer 64 can by a setting device 98 , in particular a control device 98 respectively. The adjustment preferably takes place via a signal line 99 remotely operated by the controller 98 ago. In the 11 In addition to the pressure level denoted by P in parentheses, three pressures P1, P2 and P3 are denoted by different levels or pressure levels P1, P2 and P3, which in an advantageous embodiment optionally by corresponding control of the pressure reducer 64 in the supply route 66 is available. These pressure levels P1, P2 and P3 correspond to different pressure-on-position force levels (see further development below).

In an advantageous embodiment, not shown, two different pressure levels P (eg P _DS for the contact force at the pressure point and P _DW for the contact force between the printing unit cylinders 06 ; 07 ) via two adjustable, in particular remotely adjustable pressure reducer 64 in two supply lines 66 be made available. In an advantageous embodiment, however, during the process for adjustment in a supply line 66 successively the pressure level P _DS for the contact force at the pressure point 05 and the pressure level P _DW for the contact force between the printing cylinders 06 ; 07 to be provided. In this case, during the adjustment process, for example via the pressure reducer, first the pressure level P _DS for the contact force at the pressure point 05 provided (and via the control device 98 or the machine control and the transfer cylinder 06 as required. Thereafter, the pressure level P _DW for the contact force between the forming and transfer cylinders 06 ; 07 provided and adjusting the form cylinder 07 performed. For the case described below, different pressure levels P1, P2, P3 (ie, resulting force levels) from each other for adjusting the cylinders 06 ; 07 are provided depending on certain machine data and / or certain consumable data and / or specific operating data, one of several, z. B. three, different pressure levels (eg P _DS1 , P _DS2 , P _DS3 for adjusting the transfer cylinder 07 selected, and then the form cylinder 07 set with a few, or also one of possible pressure levels P _DW4 , P _DW5 , P _DW6 . This variant offers a very high degree of adaptation to the conditions optimal for printing. The procedure described below for providing corresponding different specifications using the example of P1, P2 and P3 is based on the application with different treatment of transfer cylinders 06 and form cylinder 07 transferred to. In this case, then for that the transfer cylinder 06 a set of default values are available and maintained, while for the forme cylinder 07 relevant one or more own default values may be maintained. The pressure reducer 64 is then successively with the selected default value for the pressure level P _DS (from eg P _DS1 , P _DS2 , P _DS3 , ZB depending on the type of paper) and then with the selected default value for the pressure level P _DW (from eg P _DW4 , P _DW5 , P _DW63 , eg depending on the type of blanket) (see 23 ).

The inputs already related to 7 mentioned valves 56 , in particular multi-way valves, per adjustable cylinder 06 ; 07 are now with the supply line 66 the pressure P (or P1, P2, P3) connected. At two above-mentioned levels for forming and transfer cylinders 06 ; 07 are the inputs of the movable transfer cylinder 06 associated valves 56 z. B. with the pressure P _DS and the inputs of the form cylinders 07 associated valves 56 connected to the pressure P _DW . The outputs of the valves 56 are, for. B. via a common return line 101 , with the fluid reservoir 61 connected. The valves 56 are by a control device 103 , z. B. one of the two control devices 98 and 103 comprehensive common control device, adjustable. The adjustment preferably takes place via a signal line 102 remotely operated by the controller 103 ago.

The control device 98 and or 103 can, for. B. as a program routine, in a control room 104 or control computer 104 (dashed in 11 ) be located to control the printing press. If, for example, a command "pressure on" is output via a program routine or manually via an input means or a switch, the valves become 56 the cylinder concerned 06 ; 07 or printing units 04 by the control device 103 switched so that the ali 43 communicate with the pressure P of the supply line. With the command "pressure-down" the valves become 56 z. B. switched such that the actuators 43 communicate with the pressure level P _{L of} the reservoir.

A place of not purely manually movable executed stops 41 via the actuators as pressure medium actuators 46 executed adjusting means 46 For example, either advantageously via its own, a pressure P _S providing supply path 67 (shown) or possibly integrated into the above-mentioned pressure levels P (or P1, P2, P3). As in 11 illustrated, the pressure P _S providing fluid as a gaseous pressure medium, for. As compressed air, be provided in an open system. An input of one with the assigned actuator 46 connected valve 68 stands with the supply line 67 in conjunction, depending on the configuration of the actuator 46 (acting double-acting in both directions or only in one of two possible directions) one or two outlets of the valve 68 with one or two inputs of the actuator 46 are connected. Also the valves 68 are preferably by a control device, for. B. by means of the control device 103 adjustable. Preferably also here the adjustment via a signal line 106 remotely operated assigned by the control device 103 ago.

In an in 11 illustrated development is also for fixing the stop 41 an actuatable holding means 69 , For example, a plunger, provided by means of which the stop 41 can be kept in its substantially force-free position without changing its position when relieved by pressure-off points. Also this holding means 69 can for the purpose of actuation or release via appropriate lines and other valves 71 with the pneumatic supply line 67 be connected, and advantageous over the control device 103 be put. In the example shown, the holding means 69 trained to stop 41 optionally (when activated) frictionally engaged with respect to the bearing block 34 to terminals.

In an advantageous embodiment, instead of the stop 41 fixing holding means 69 a in 13 represented holding means 74 provided, by means of which the transmission member 47 , in particular the piston rod 47 or a corresponding extension piece, can be clamped. The holding means 74 can be in the actor 46 integrated, or as shown between actuator 46 and stop 41 be arranged in such a way that the transmission member 47 optionally fixable or freely movable in its direction of movement. The holding means 74 has, for example, two jaws 76 with breakthroughs 77 or at least recesses for embracing the transmission member 47 on, which is so with the transmission member 47 are in operative connection that they are in a first operating state in which the longitudinal axis of the breakthroughs 77 parallel to the transmission link 47 run, the transmission link 47 release, and in a second operating state, in which the longitudinal axes of the apertures 77 opposite the longitudinal axis of the transfer member 47 tilted, in particular spread apart, the latter with respect to a movement is clamped. Preferably, the retaining means 74 self-locking trained so that when not actuated holding means 74 , z. B. by the force of a spring 78 , the second operating state is taken. The operation of the jaws 76 takes place via such inclined surfaces of an actuator 79 that the jaws 76 in a first position of the actuator 79 tilted (see above) and not tilted in a second position. The holding means 74 , in particular the actuator 79 , in principle, manually, for example via a corresponding actuator, or advantageously by means of an actuator 81 , in particular remotely operable, non-manually operable. The actuator 81 is in 13 as acted upon with pressure medium cylinder 81 formed in which the piston formed as an actuator 79 is movable. Upon application of the pressure P _S ( 13a ) is carried out a release of the clamping - here by appropriate alignment of the jaws 76 or their breakthroughs 77 , In relaxation ( 13b ) he follows through the spring 78 a spreading or tilting of the jaws 76 and thus a jamming.

A return of the stop 41 can either through the in 7 illustrated spring 48 or else - as in 13 shown dashed - active through the training of the actor 46 cylinder which can be actuated as a pressure medium with a double-acting piston, that is to say with two pressure medium supply lines, one on each side of a piston 52 ,

In the illustration after 11 are the storage units 14 all four cylinders 06 ; 07 of the double printing unit 03 over a common supply route 66 through a common pressure accumulator 63 provided. This can be to a common line of the line of the supply line 66 even the storage units 14 the cylinder 06 ; 07 all double printing units 03 a printing tower 01 be connected. Ie. to supply the storage units 14 a printing tower 01 with the pressure P (P1, P2, P3) is a supply line 66 provided, which serially and / or in parallel (as shown) with the valves 56 the individual storage units 14 connected is.

In an in 21 variant shown is the supply of storage units 14 a printing unit 01 , in particular a printing tower 01 , with pressure medium of the adjustable pressure P (P1, P2, P3) several times, z. B. double, in particular for with separate units for each of the two partial pressure units 01.1 ; 01.2 , executed. In particular, for the storage units 14 the cylinder 06 ; 07 of printing works 04 , which are on one side of the track 02 are located (eg partial pressure unit 01.1 ) a first supply system 75.1 with all the necessary aggregates, z. B. with a first supply line 66.1 , a first pressure reducer 64.1 , a first accumulator 63.1 and a first compressor 62.1 , and for the storage units 14 the cylinder 06 ; 07 of printing works 04 , which are on the other side of the track 02 are located (eg partial pressure unit 01.2 ) a second supply system 75.2 with all the necessary aggregates, eg. B. with a second supply line 66.2 , a second pressure reducer 64.2 , a second pressure accumulator 63.2 and a second compressor 62.2 , be provided. In 1 is the double arrangement of supply systems for a printing tower 01 indicated schematically.

This double training per printing tower 01 is especially in printing towers 01 advantageous, which in the nature of 2 to 4 in the area of bruises 05 are formed separable. In this case, then, for example, all storage units 14 the one partial printing unit 01.1 through the aggregates of the first supply system and all storage units 14 the other partial printing unit 01.2 supplied by the aggregates of the second supply system with the pressure medium of the corresponding pressure level P (P1, P2, P3). The supply systems are designed here as fully functional pressure medium circuits.

In terms of redundancy, it is particularly advantageous if the two supply systems 75.1 ; 75.2 are formed at least one point selectively connectable to each other. The connection should each be downstream of the compressor 62.1 ; 62.2 , ie in relation to the environment overpressure having line region of the supply circuit, be arranged. This can basically be done between the two supply lines 66.1 . 66.2 in the range of the already correctly set pressure P (P1, P2, P3) via an optional openable valve. In the illustrated advantageous example, however, a connection in each case the high pressure P _H having pressure medium branch via a switchable valve 65 having direction 70 created. Thus, in the event that one of the two compressors 62.1 ; 61.2 fails, the valve 65 open, and the other supply route 66.1 ; 66.2 through the intact compressor 62.1 ; 62.2 be supplied with.

In the in 11 illustrated embodiment, all four cylinders 06 ; 07 through actuators 43 stored on / off adjustable, but only the attacks 41 the two form cylinder 07 and one of the transfer cylinders 06 not by hand, but via the pressure-actuated actuators 46 , in particular remotely operated, are adjustable. The stop 41 of the other transfer cylinder 06 is, for example by means of a designed as a screw actuator 46 , adjustable and lockable. He must therefore, for example, no holding means 69 exhibit.

In an above simpler variant, although all four cylinders 06 ; 07 by means of actuators 43 mounted linearly movable, with only the two transfer cylinders 06 movable stops 41 (if necessary with the above actuators 46 and / or holding means 69 ) exhibit.

In a further simplified embodiment, one of the two transfer cylinders 06 Although adjustable in its position, but not in the sense of an on / Abstellbewegung operatively movable but stored frame-fixed. The three other cylinders 06 ; 07 are then movably mounted in the sense of an on / off, in a first variant, all these three cylinders 06 ; 07 and in the second variant, only that of the specified transfer cylinder 06 different transfer cylinders 06 a movable stop 41 and possibly the holding means 69 having.

In development of the cylinder bearing are the bearing units 14 the form cylinder 07 and or the transfer cylinder 06 as in 12 shown schematically, on at least one end face even in camps 72 , z. B. linear bearings 72 , movably mounted in a direction of movement C, which is perpendicular to the cylinder axis of rotation and at least one component perpendicular to the direction of adjustment S has. Preferably, the direction of movement C is selected perpendicular to the direction of adjustment S and causes unilateral actuation an inclination (so-called. "Cooking") of the relevant cylinder 06 ; 07 , The adjustment of the cylinder 06 ; 07 can be via a manual or motorized actuator 73 , z. B. via a handwheel or preferably via a motor-operated adjusting spindle. Such additional storage of the storage unit (s) 14 on the form cylinder 07 allows it to be tilted and a passport adjustment, and allows on the transfer cylinder 06 its inclination.

The in the above embodiment of the storage units 14 provided actuator 43 is designed to provide a suitable for switching on or off adjusting travel .DELTA.S, and therefore preferably has a stroke corresponding at least .DELTA.S. The actor 43 is for adjusting the Anstelldruckes against each other employed rollers or cylinders 06 . 07 and / or provided for carrying out the Druckan - / - off and trained accordingly. The travel ΔS (or stroke) is for example at least 1 mm, advantageously at least 1.5 mm, in particular at least 2 mm. In 14 is an advantageous embodiment of a -. B. designed as a prefabricated component - actuator element 59 shown.

The actuator element 59 also includes a supply line 83 to supply the pressure chambers 82 with pressure medium of the pressure P. Preferably, the two pressure chambers 82 supplied by a common supply line and thus depressed or relieved in the same way. In 14 is the upper piston 43 but exemplary for both pistons 43 in a retracted and the lower piston 43 exemplary for both pistons 43 shown in an extended position. The supply line 83 For this reason, it was also only partially characterized as pressurized.

The piston 43 is against the pressure medium chamber 82 through one on the circumference of the piston 43 circumferential, close to pressure seal 86 sealed and a pressure chamber close sliding guide 87 guided. Advantageously, in addition, a second seal 88 and a second sliding guide 89 in a pressure chamber remote area of the piston 43 be provided. In a particularly advantageous embodiment, instead of or in addition to the second seal 88 The piston 43 to the outside in addition by a membrane 91 , z. B. rubber, in particular a rolling diaphragm 91 sealed. This is on the one hand around with the piston 43 and on the other hand on its outer circumferential line completely with the base body 84 or other fixed installations of the actuator element 59 connected.

In another, in 16 illustrated advantageous embodiment of the storage unit 14 are in contrast to the first embodiment, the actuators 43 not in a separate actuator element (previously 59 ), but in the frame construction, z. B. the pressure-point remote side support 94 , integrated. In this case, in the embodiment of actuable as pressure medium actuators 43 trained actors 43 the pressure cylinder as holes in the side support 94 be provided. Also, the feeders in this pressure medium space can as holes in the side support 94 be educated. However, it can also be differently designed force-controllable actuators 43 (As based on hydraulic, magnetic or piezoelectric forces) in the side support 94 be provided integrated. The recognizable with the appropriate components 7 matching parts are in 16 not specially provided with reference numerals. This design saves space and is therefore suitable when cylinders 06 ; 07 small extent, z. B. with a simple scope (only a circumference corresponding to a newspaper page) to be made. For the arrangement of the storage unit 14 in the printing unit 01 , the control and the procedure for setting and presetting is that in connection with the first execution of the storage unit 14 apply accordingly.

B. in the carriage 34 or storage block 34 , integrated. This is space saving and therefore particularly suitable when cylinder 06 ; 07 small extent, z. B. with a simple scope (only a circumference corresponding to a newspaper page) to be made. This applies regardless of the specific design of the force-controllable actuator 43 as based on hydraulic, magnetic or piezoelectric forces. Also in 17 are the ones made with the appropriate components 7 matching parts are in 16 not all provided with reference numerals. For the arrangement of the storage unit 14 in the printing unit 01 , the control and the procedure for setting and presetting is that in connection with the first execution of the storage unit 14 apply accordingly.

18 and 19 show further versions of the storage unit 14 , wherein in addition to at least one pressure point remote actuator 43 at least one actuator close to the pressure point 97 arranged. Generally speaking, at least one (here two) is the pressure point when activated 05 acting actor 43 and at least one (here two) actor away from the pressure point when activated 97 intended. The actors 97 are so between the movable and the frame-fixed part of the storage unit 14 arranged that when activated a force in one direction from the pressure point 05 away on the movable part of the storage unit 14 can be applied. The actors 43 are - as in the previous examples of the storage unit 14 - Such between the movable and the frame-fixed part of the storage unit 14 arranged that when activated a force in one direction to the pressure point 05 towards the movable part of the storage unit 14 can be applied. The actors 97 can be shown in the movable part (eg the slide 34 ) or in a frame-fixed part of the storage unit 14 be integrated. The at least one actor 97 is preferably also as force controllable actuators 97 (as based on hydraulic, magnetic or piezoelectric forces) formed.

In 18 are the off-press actuators 43 again in the movable part of the storage unit 14 , z. B. in the carriage 34 , integrated while in 19 Part of a frame-fixed actuator element 59 are. You can, however, like in 16 also be integrated in the frame.

In not shown variant, instead of the two single-acting actuators 43 ; 97 a double-acting actuator may be used, which can optionally be activated towards the pressure point or away from the pressure point, ie can be acted upon by corresponding pressure medium.

The variant of 18 respectively. 19 with at least one to the pressure point 05 acting and at least one of the pressure point 05 away acting actor 43 ; 97 or a double-acting actuator (not shown) is particularly advantageous in printing units 03 or double printing units 04 whose cylinder 06 ; 07 are aligned substantially in a vertical arrangement (with or without slight horizontal offset) to each other. With this additional actuator 97 is z. B. the own weight compensated. This is the case in particular as I-pressure units 01 trained printing units 01 how they z. B. are used in commercial printing. 20 schematically shows the arrangement of the cylinder 06 . 07 such an I-pressure unit 01 with the storage units 14 , In 20 are the cylinders 06 ; 07 the I-pressure unit 01 on top of each other on a plane (like the plane E in 2 ) arranged. This level then takes z. B. an angle between 76 ° and 87 °, in particular between 80 ° and 85 ° to the plane of the horizontal incoming web. In principle, however, the arrangement can also be other than in a plane. As in 20 exemplified, z. B. the two upper cylinder 06 ; 07 on the near-printed side of the storage unit 14 one or more second actuators 97 on, which can compensate, for example, at a corresponding pressure level, the weight. The lower cylinders 06 ; 07 have no second actuators here 97 on. When pressure is applied, however, they must be set at a pressure level higher than the upper cylinders by an amount corresponding to the weight force 06 ; 07 ,

As above 11 already indicated with the differing pressure levels P1, P2 and P3, it may be provided in a particularly advantageous development, different pressure levels P1, P2, P3 (ie, resulting force levels) for the employment of the cylinder 06 ; 07 to provide as a function of certain machine data and / or certain consumable data and / or specific operating data and preferably to provide corresponding default values.

The adjustable "pressure levels" are understood in Generalization of the concretely present advantageous example as adjustable "force levels" for the contact force and are conceptual in generalizing the doctrine accordingly transferred to.

The above procedure when adjusting the cylinder 06 ; 07 can then be maintained substantially. It is then z. B. only a program-based or manual selection of the relevant pressure level P; P1; P2; P3 from a plurality of possible levels with regard to the criteria determining the level to be set (eg printing stock and / or printing blanket). Of particular advantage is an embodiment, wherein a default for the pressure level P; P1; P2; P3 as a function of a condition, in particular a surface finish, of the material web to be printed 02 and / or depending on the blanket used, in particular properties of blankets from different manufacturers, takes place. A plurality of possible input values for the relevant criterion (eg material web 02 or blanket) are different basic values for a pressure level P to be set; P1, P2; Assigned to P3.

This assignment between criterion and basic value can be the operator z. B. present in tabular form as information, wherein the input value for the criterion associated basic value for the pressure level P; P1; P2; P3 then z. B. can be entered as desired value for the pressure in an input means of the control station accordingly. In an advantageous embodiment, the corresponding associations between the possible "input values" (eg types of paper or blanket types) and the recommended or predetermined "basic values" for the pressure level P; P1; P2; P3, however, in a data memory of the control device 98 or the central computer 104 held, displayable via a display device and an input means selectable.

The The procedure is described below using the example of pressure levels P1, P2, P3 explained. In principle, however, this is dependent on the execution of the used force-controllable actuator to transfer other physical quantities. The size to be controlled can then z. B. the current, the electrical voltage, an electrical line or other for the magnitude of the force generation be responsible physical quantities. Essential is that different input values for that criterion (Material web and / or blanket) different resulting screw down are assignable. The adjustable "pressure level" is shown below thus for the adjustable contact force.

22 and 23 show by way of example in each case at least one section of a z. B. on the display device to the controller 98 , to the control room 104 or to the central computer 104 belonging control unit 98 displayed or at least displayable program mask, each of these program masks serves the purpose, in conjunction with at least one of the control device 98 belonging control or input means, eg. As a keyboard or a pointer instrument, the z. B. from a cylinder 06 ; 07 Adjusting force applied to a neighboring body of revolution in a roll strip individually as needed and preferably remotely controlled an existing setting, z. B. also during an ongoing production of the printing unit 04 to be able to change. Both program masks show, by way of example, in each case schematically a printing unit designed as an eight-high tower 01 , where vertically over each other four double printing units 03 for generating a 4/4 pressure, wherein the respective transfer cylinders 06 the double printing works 03 are employed against each other. To each of the transfer cylinders 06 the double printing works 03 each is a form cylinder 07 hired. For details on the training of these double printing units 03 will be on the 1 to 4 each referenced with the associated description.

For adjustment between the transfer cylinders 06 the double printing works 03 exerted contact force can several, z. B. three different in magnitude pressure levels P1, P2, P3 be provided, each of these pressure levels pressure levels P1, P2, P3 depending on z. B. of a surface condition of the in the printing unit 01 printed substrate 02 , in particular the material web 02 , as a criterion is selected, the surface texture z. As the roughness and / or smoothness and / or the uniformity of the surface and / or the acceptance behavior of ink and / or the absorbency of the printing material 02 and / or the amount of coating at a coated surface of the printing substrate 02 concerns. For example, in order to produce a good print quality for a rough newsprint paper, a three to four times higher contact pressure is required compared to a very smooth art paper. The choice of the surface texture of the printed substrate 02 dependent pressure levels P1, P2, P3 can be in a comfortable way z. B. with displayed in the program screen or at least displayable buttons 107 ; 108 ; 109 respectively. In the in the 22 and 23 Each program mask shown is a field titled "Paper Selection" 111 showing in this field 111 several, z. B. three buttons 107 ; 108 ; 109 are provided for selecting the input value for a paper with a rough or a normal or a smooth surface. Each of these selectable input values is a specific, preferably specified by the manufacturer of the printing press, in the program masks unspecified value for the basic value of the pressure level P1; P2; P3, ie for between the transfer cylinders 06 the double printing works 03 associated pressing force, wherein the respective one of the pressure levels P1, P2, P3 associated pressing force by means of the respective storage unit 14 the transfer cylinder 06 arranged actuators 43 after the user of the press has made his decision regarding the selectable input values. The selection may also be made in other suitable ways, e.g. B. by opening so-called. "Pulldown" window and confirm the selection are made.

Furthermore, it can be provided that the respective between the transfer cylinders 06 the double printing works 03 applied pressing force starting from at least one of the selectable pressure level P, P1, P2, P3, preferably of all selectable pressure levels by a fine adjustment is variable. In the program masks of the 22 and 23 shown example, the fine adjustment in one of the selectable pressure level P, P1, P2, P3 outgoing percentage addition to increase the respective contact pressure, wherein the addition of z. B. in increments of one percent up to 100%, ie up to a doubling of the respective selected pressure level or the contact force corresponding value can take place. The added to the respective selected pressure level P, P1, P2, P3 addition is in the program masks z. B. within the printing unit shown schematically 01 z. B. by a numerically displayed percentage value in association with the respective transfer cylinders 06 the double printing works 03 in a window 112 appears. In the in the 22 and 23 example shown is the set addition for all double printing 03 + 5% each. It goes without saying that deviating values as well as for the double printing units 03 in each case also different values are adjustable.

Furthermore, it can be provided that each between one of the transfer cylinder 06 and one of the forme cylinders 07 applied contact force is changeable. The setting between one of the transfer cylinders 06 and one of the forme cylinders 07 applied contact pressure depends on Drucktucheigenschaften, z. B. after the elasticity and / or the compressibility of the transfer cylinders 06 drawn up blankets. 23 shows that z. B. in addition to the adjustability between the transfer cylinders 06 the double printing works 03 applied contact pressure in association with preferably each double printing unit 03 each a selection menu 113 is provided, each selection menu 113 z. B. has a list with several names or names of blankets with different technical properties, wherein the on the respective transfer cylinder 06 each currently wound blanket is selectable. Depending on the selected blanket is between the respective transfer cylinder 06 and the associated form cylinder 07 a specific, for the respective blanket specified value for the contact pressure or the pressure level P, P4, P5, P6 set, each of these settings in turn specify a certain level for the contact force.

Starting from this pressure level P, P1, P2, P3, which can be selected as a function of the blanket, can preferably be set between all transfer cylinders 06 and the respective associated form cylinder 07 the actually applied contact force can be changed by a fine adjustment, wherein the change z. B. as an addition z. B. in increments of one percent up to 100%, ie up to a doubling of the respective selected pressure level P, P1, P2, P3 of the contact force corresponding value can take place. The addition related to the selected pressure level is displayed in the program mask 23 z. B. within the printing unit shown schematically 01 z. B. by a numerically displayed percentage z. B. in association with one of the form cylinder 07 the double printing works 03 appears and is there z. B. also changeable or editable. In the in the 23 Example shown is the set addition for three of the four double printing units 03 + 15% each and for the top double printing unit 03 z. + 10%. It goes without saying that deviating values as well as for the double printing units 03 in each case also different values are adjustable.

The respective an input force associated with an input value (pressure or force level) and their fine position, be it the adjustment of the contact pressure depending on the surface condition of the printed substrate 02 and / or the adjustment of the contact pressure as a function of properties of the printing blanket used, in each case by means of the respective storage unit 14 the transfer cylinder 06 and / or the form cylinder 07 arranged actuators 43 ,

The changes the selection and / or the change The fine-tuning - for the criterion "paper selection" and / or for the criterion "blanket selection" - can be done through a forgivable password the underlying software is protected. In particular, however the criterion "paper selection" can be freely changed, However, the pressure technically more sensitive criterion "blanket selection" regarding selection and / or Fine-tuning for security reasons.

It is particularly advantageous when using kraftsteuerbarer employment that different thicknesses of the material web 02 must not be taken into account in the setting, since this is automatically taken into account by force-based placement as opposed to way-based placement. As described above, however, it is preferable to consider the surface property in adjusting the pressing force and the pressure level, respectively.

In embodiments, wherein the pressure levels P, P1, P2, P3 different cylinders 06 ; 07 and / or different printing units 04 and / or different double printing units 03 a printing unit 01 can be selected individually or be fine adjustable, either a plurality of supply systems (pressure medium circuits) can be provided in a first embodiment, or it can be individually adjusted cylinder 06 ; 07 or cylinder groups several controllable pressure reducers 64 provided on a common supply line.
