The printing press 01 is for example a printing press used in value printing 01 , This printing press 01 is as a preferably sheet-shaped substrate 09 printing press 01 trained, so as a sheet-fed press 01 , This printing press 01 has at least one printing unit 02 with at least one printing unit 08 and at least one inking unit, wherein the at least one printing unit 08 at least one form cylinder 07 having. Preferably, in the at least one printing unit 02 several printing units 08 and several inking units provided to print in a same production different inks on the same substrate 09 to print, for example, according to the number of these color works. In one embodiment, in the same printing unit 02 printing units 08 arranged, which work according to different pressure principles. For example, at least one printing unit 08 as a flat printing unit 08 , For example, an offset printing unit 08 trained and is at least another printing unit 08 as a high pressure work 08 for example, as a steel engraving printing plant 08 and / or an indirect high-pressure plant 08 educated. These different printing works 08 For example, then print the same substrate in the same production 09 , more preferably by means of at least one common transfer cylinder 06 , The printing press 02 preferably has at least one printing material source 03 in the form of a sheet feeder 03 on. The printing press 01 preferably has at least one sheet storage 04 which preferably has at least one and more preferably at least three discard piles. For example, the printing press has ten forme cylinders 07 on. A sheet-fed rotary printing machine 01 with a printing unit 02 with several printing units 08 is also exemplary in 1 shown.

Preferably, the at least one printing unit 02 at least a pair of as blanket cylinders 06 trained transfer cylinders 06 on, through whose common contact area a pressure nip 16 is fixed. Preferably, each of the at least two transfer cylinders 06 with at least one forme cylinder 07 and more preferably several, for example four, form cylinders 07 in rolling contact. The printing unit is preferred 02 as a multi-color printing unit 02 educated. Each of these form cylinder 07 is preferably associated with at least one inking unit. Preference is given to the at least one forme cylinder 07 arranged at least one printing form in the form of a printing plate. The at least one forme cylinder 07 is so as at least one plate cylinder 07 educated. Preferred is on each forme cylinder 07 exactly one printing form arranged or provided, whose extension in an axial direction A of the forme cylinder 07 preferably at least 75% and more preferably at least 90% of an expansion of a cylindrical bale 12 of the forme cylinder 07 in this axial direction A corresponds.

The printing form preferably has a dimensionally stable support plate and at least one plate coating. The dimensionally stable carrier plate consists for example of a metal or an alloy, for example aluminum or steel. In at least one dry offset printing unit or waterless offset printing unit, at least one support plate made of steel is preferably used. In at least one wet offset printing unit, at least one aluminum support plate is preferably used. The carrier plate preferably has a thickness, that is to say a smallest dimension of 0.25 mm to 0.3 mm. The at least one plate coating defines a printed image of the printing plate. The printed image can be defined, for example, in that parts of a surface of the printing form have hydrophobic properties, while other parts of the surface of the printing plate have hydrophilic properties. Depending on the characteristics of an ink used, only selected areas of the printing form will then transfer this ink. Such a printing form transfers color after a planographic printing process, in particular offset printing process. In this case, a waterless offset printing method can be used or a so-called wet offset printing method can be used, for which the printing unit then has at least one dampening unit. However, the printed image can also be determined, for example, by first applying the entire surface of the plate coating and selectively hardening it in an exposure step, while the uncured regions are washed out, for example with water. This results in not washed-out areas which are arranged elevated relative to the support plate and washed-out areas which are lower and are formed for example by the exposed support plate. Such a printing form transfers color to the corresponding transfer cylinder after a high-pressure process 06 from where they are on the substrate 09 is transmitted. Since the print image only from the transfer cylinder 06 on the substrate 09 is transmitted, this is an indirect high pressure process.

Both the leading end in printing operation and the trailing end of the printing forme in the printing operation preferably have a contact area which has no ink transfer plate coating, but a clamping of the printing plate on the plate cylinder 07 serves. Preferably, the printing forme in the contact areas consists exclusively of the dimensionally stable carrier plate.

The printing unit 02 works best in perfecting, with both sides of the substrate 09 in the nip 16 dyed at the same time. Further preferred are in the printing nip 16 multicolored print images in a single printing step on the substrate 09 transfer. These multicolor print images are preferably composed of individual color partial color images, previously of several cylinders 07 on the appropriate transfer cylinder 06 transferred and collected there. The printing unit 02 preferably consists of two substantially identically constructed halves. Each of the halves has a preferred as a blanket cylinder 06 trained transfer cylinder 06 on. The plate cylinders 07 are preferably colored by one inking unit with a different printing ink. The plate cylinders 07 preferably each transmit at least one printed image on the corresponding transfer cylinder 06 to which they are employed.

The at least two front pressing elements 23 are preferred with the front body 37 flexibly connected, more preferably such that they can not be removed from it, but are still movable relative to it, in particular during its deformation. The at least two front pressing elements 23 are preferred with the at least one radially inner front clamping element 26 flexibly connected, more preferably such that they can not be removed from it, but are still movable relative to it, in particular during its deformation. In particular, therefore, the at least one radially inner front clamping element is preferred 26 with the at least two front contact elements 23 so flexibly connected, so that a shortening of the at least one front pressing element 23 inevitably a movement of the at least one radially inner front clamping element 26 opposite to the front clamping direction B causes.

In a preferred embodiment, the at least two front pressing elements 23 essentially, in particular apart from a deflection or curvature, arranged parallel to one another and extend in the axial direction A and substantially also in a second extension direction orthogonal thereto, which preferably has at least one radial component. Preferably, however, the second extension direction is slightly curved and each front pressing element 23 slightly curved, as the at least two front pressing elements 23 constantly under a more or less great bias.

Both sides of the at least one front Klemmlöseschlauchs 24 At least one clip element is a removal of ends of the at least two front pressing elements 23 arranged to prevent each other beyond a maximum distance. This causes inflation of the at least one front grommet hose 24 the at least two front pressing elements 23 not just swing away from each other, but from the at least one front Klemmlöseschlauch 24 buckle outward since their ends do not extend from the ends of the adjacent pressing elements 23 can remove.

This occurs, for example, in the form of a deflection of the at least one rear pressing element 63 and preferably by means of mutually opposite deflections of the at least two rear pressing elements 63 , This causes a movement of the at least one radially inner rear clamping element 66 from the at least one radially outer rear clamping element 62 away and thus opening a rear clamping gap 67 , The rear clamping gap 67 is preferred by the at least one radially outer rear clamping element 62 on the one hand and the at least one radially inner rear clamping element 66 on the other hand. The at least two rear contact elements 63 are preferred with the rear body 71 flexibly connected, more preferably such that they can not be removed from it, but are still movable relative to it, in particular during its deformation. The at least two rear contact elements 63 are preferred with the at least one radially inner rear clamping element 66 flexibly connected, more preferably such that they can not be removed from it, but are still movable relative to it, in particular during its deformation. In particular, therefore, the at least one radially inner rear clamping element is preferred 66 with the at least two rear contact elements 63 so flexibly connected, so that a shortening of the at least one rear pressing element 63 the at least one radially inner rear clamping element 66 inevitably a movement of the at least one radially inner rear clamping element 66 causes against the rear clamping direction C.

In a preferred embodiment, the at least two rear pressing elements 63 essentially, in particular apart from a deflection or curvature, arranged parallel to one another and extend in the axial direction A and substantially also in a second extension direction orthogonal thereto, which preferably has at least one radial component. Preferably, however, the second extension direction is slightly curved and each rear contact element 63 slightly arched, since the at least two rear pressing elements 63 constantly under one more or stand less bias.

Both sides of the at least one rear clamping hose 64 At least one clamping element is a distance from ends of the at least two rear pressing elements 63 arranged to prevent each other beyond a maximum distance. This causes inflation of the at least one rear gripper hose 64 the at least two rear contact elements 63 not just swing away from each other, but from the at least one rear gripper hose 64 buckle outward since their ends do not extend from the ends of the adjacent pressing elements 63 can remove.

As long as the at least one tension drive 104 is disabled, that is at least one sled 102 in a first, also referred to as peripheral location, the second channel wall 19 closer position of the at least one carriage 102 disposed in particular because of the at least one return element 106 on the at least one carriage exerted restoring force.

The at least one tensioning device 101 preferably has at least one fixing device 109 on, by means of which the at least one second clamping device 61 is fixable in their position and in particular while maintaining a tension of the printing plate, in particular at least with respect to movements on the second channel wall 18 to. In the following, two different embodiments of the fixing device 109 described.

A first embodiment of the fixing device 109 is described below. In the first embodiment, the fixing device 109 at least one preferably adjustable rear spacer 131 on, which is preferred as at least one rear adjusting screw 131 is trained. The at least one rear spacer 131 is by means of a bearing, which preferably has at least one thread or is formed as a thread, preferably in the at least one carriage 102 and in the at least one rear clamping device 61 stored, in particular in the rear body 71 , But it is also possible, the at least one rear spacer 131 by means of a bearing in a component of the cylinder bale 12 to store. The at least one rear spacer 131 is relative to the at least one sled 102 movable, in particular in its relative position to the at least one carriage 102 adjustable, for example by a screw in the at least one thread. The at least one rear spacer 131 is preferably together with the at least one carriage 102 movable. The at least one rear spacer 131 is in particular in at least one retracted position and in at least one and preferably a plurality of extended positions relative to the at least one carriage 102 arranged. In the at least one extended position of the at least one rear spacer 131 the at least one rear spacer protrudes 131 preferably further in one on the second channel wall 19 pointing direction via one of the second channel wall 13 facing rear edge surface 132 of the at least one sled 102 out than in the retracted position.

The at least one return element 106 causes, as already described, a restoring force on the at least one carriage 102 , which is oriented counter to the clamping direction E. If no opposing forces act, the at least one slide 102 So against the second channel wall 19 pressed. Depending on the position of the at least one rear spacer 131 will be the at least one sled 102 but prevented from the second channel wall 19 to come as close as possible and especially to its outskirts. Is the at least one rear spacer 131 in the retracted position and is the at least one rear spacer 131 and / or the at least one sled 102 even with the second channel wall 19 in contact, it is at least a sled 102 further from the at least one front clamping device 21 arranged away as if the at least one rear spacer 131 in an extended position and in contact with the second channel wall 13 located. Correspondingly, even the smallest distances between the at least one front clamping opening behave 27 and the at least one rear clamping opening 67 , One in the at least one front clamping device 21 and in the at least one rear clamping device 61 clamped and around the cylinder barrel 12 placed printing form is thus with deactivated tensioning drive 104 depending on the position of the at least one rear spacer 131 more or less tense. The fixing device 109 in the first embodiment, therefore, the clamping force of the pressure plate and / or the restoring force of the at least one restoring element acts 106 against and thus fixes the at least one slide 102 and thus the at least one rear clamping device 61 ,

The fixing device 109 in the first embodiment is preferably operated such that one in both the at least one front clamping device 21 as well as in the at least one rear clamping device 61 clamped printing form is first stretched by the at least one tensioning drive 104 is activated, for example by the tension hose 104 is pressurized and expands so that it at least one slide 102 emotional. In this case, the at least one rear spacer 131 initially in the retracted position relative to the at least one carriage 102 arranged. The at least one sled 102 and thus the entire at least one rear clamping device 61 moves to the at least one front clamping device 21 to. This will cause the around the plate cylinder 07 wound printing form stretched. The at least one sled 102 preferably moves so far that a desired voltage of the printing form is reached or more preferably at least slightly exceeded. Following is the at least one rear spacer 131 moved from the retracted position to a defined extended position. Following is the tension drive 104 deactivated, for example by the pressure in the tension hose 104 is reduced, for example, to ambient pressure, in particular atmospheric pressure. Optionally, the at least one carriage moves 102 back to the second channel wall 19 until the at least one rear spacer 131 the second channel wall 19 in each case at least one and preferably exactly one Distance contact point 133 touched and thereby the at least one sled 102 is stopped.

The rear clamping device 61 is in this state, as already described, thereby held in position that the restoring force of the at least one return element 106 and / or the tension of the printing forme the at least one carriage 102 and thus the at least one rear clamping device 61 against the second channel wall 19 presses, but in one by the position of at least one rear spacer 131 fixed distance. For this, no drive must remain permanently activated and, in particular, no hose must be permanently pressurized. The at least one tension drive 104 that at least a rear spacer 131 and that at least one rear actuator 64 are preferred against a same component of the carriage 102 and the at least one rear clamping device 62 supported, more preferably against the rear body 71 , Actuations of the at least one tensioning drive 104 , the at least one rear spacer and the at least one rear control element 64 are preferably independently executable.

The exact position of the at least one rear spacer 131 defines the minimum distance of the at least one carriage 102 from the second channel wall 19 , Due to the exact position of the at least one rear spacer 131 Thus, a maximum acting on the tensioned pressure form clamping force is set. Preference is given to several, more preferably at least four of the described rear spacers 131 arranged in the axial direction A spaced from each other. In a preferred embodiment, the at least one rear spacer 131 by means of at least one as a distance drive 134 trained drive 134 adjustable in position. The at least one distance drive 134 is preferred as at least one electric motor 134 educated. The at least one distance drive 134 Can also be used as a pneumatic and / or hydraulic drive 134 be educated. The at least one distance drive 134 and / or the at least one rear spacer 131 further preferably comprises at least one distance sensor having a position of the at least one distance drive 134 , For example, detects a rotational angle position of the at least one electric motor and / or the one position of the at least one rear spacer 131 detected. Preferably, the at least one distance sensor is connected to the machine control and / or is the at least one distance drive 134 connected to the machine control. Alternatively or additionally, a position of the at least one spacer 131 manually adjustable.

A second embodiment of the fixing device 109 has at least one stop body 111 and at least one preferably in its position relative to the cylindrical bale 12 and / or the at least one carriage 102 specifically adjustable rear stop actuator 112 , For example, at least one rear stop screw 112 on. The at least one rear stop actuator 112 preferably has at least one stop gear 113 on, for example, a finer adjustment of the position of the at least one rear stop actuator element 112 to enable. The at least one rear stop actuator 112 is preferred in at least one camp 122 stored, for example, as a storage block 122 is trained. Preferably, this is at least one rear stop actuator 112 via at least one thread with the at least one bearing 122 in connection. The at least one camp 122 is preferably stationary relative to the cylindrical bale 12 arranged, for example as part of the cylinder bale 12 educated. The at least one stop body 111 is preferred on the at least one carriage 102 arranged and movable together with this. The at least one rear stop actuator 112 is preferably the maximum travel of the at least one carriage 102 limited arranged. The maximum travel of the at least one carriage 102 is then preferred at one end by the at least one rear stop actuator 112 and at another end through the second channel wall 19 limited. By changing the position of the at least one rear stop actuator element 112 with respect to the clamping direction E is the maximum travel of the at least one carriage 102 adjustable, in particular extendible and / or shortenable.

At least one carriage clamping element is preferred 114 on the at least one sled 102 arranged. The at least one carriage clamping element 114 is preferably by means of at least one as Schlittenlöseantrieb 116 trained drive 116 relative to the at least one carriage 102 movable 114 arranged. By means of the at least one carriage release drive 116 this is at least one carriage clamping element 114 with a first carriage clamping surface 117 of the at least one channel 13 into and / or out of contact. In a fixed position of the at least one carriage 102 the at least one carriage release drive is supported 116 on the one hand on the at least one slide 102 and thus on the at least one rear clamping device 61 From and supports the at least one slide release drive 116 on the other hand, via the at least one carriage clamping element 114 at the first carriage clamping surface 117 of the canal 13 from.

The at least one sled 102 and thus the at least one second clamping device 61 in turn, preferably relies on one of the first Sleigh clamping surface 117 of the canal 13 opposite second carriage clamping surface 118 of the canal 13 from. As a result, the at least one sled 102 in the channel 13 fixed. Preferably, the at least one carriage release drive 116 analogous to the principle of at least one front clamping device 21 and / or the at least one rear clamping device 61 built up.

For this purpose, the at least one carriage release drive 116 preferably at least one and more preferably at least two Schlittenanpresselemente 119 on. The at least one Schlittenanpresselement 119 is preferred as at least one carriage leaf spring 119 formed, more preferably as at least one front carriage spring package 119 , consisting of several, in particular flat adjacent leaf springs 119 consists. The at least one carriage release drive 116 preferably has at least one carriage release plate 121 on. The at least one sledge freezer 121 is preferred as at least one carriage release hose 121 formed, which is filled with a fluid and / or fillable, for example, with compressed air. Preferably, the compressed air is in an interior of the at least one carriage release hose 121 with a pressure of up to 10 bar or more acted upon and / or charged. The at least one sledge freezer 121 can also as at least one hydraulic cylinder 121 and / or at least one pneumatic cylinder 121 and / or at least one electric motor 121 be educated.

Regardless of the training of at least one sled freestanding 121 causes activation of the at least one carriage free plate 121 preferably a shortening of the at least one Schlittenanpresselements 119 and preferably the at least two Schlittenanpresselemente 119 in at least one carriage clamping direction F, which is further preferably oriented parallel to the second clamping direction C. This happens, for example, by means of a deflection of the at least one Schlittenanpresselements 119 and preferably by means of oppositely directed deflections of the at least two Schlittenanpresselemente 119 , This causes a movement of the at least one carriage clamping element 114 from the first carriage clamping surface 117 away and thus releasing the at least one carriage 102 , The at least one and preferably the at least two Schlittenanpresselemente 119 are preferred with the at least one carriage 102 flexibly connected, more preferably such that they can not be removed from it, but are still movable relative to it, in particular during its deformation. The at least one and preferably the at least two Schlittenanpresselemente 119 are preferred with the at least one carriage clamping element 114 flexibly connected, more preferably such that they can not be removed from it, but are still movable relative to it, in particular during its deformation. In particular, therefore, the at least one carriage clamping element is preferred 114 with the at least one Schlittenanpresselement 119 connected so flexible, so that a shortening of the at least one Schlittenanpresselements 119 the at least one carriage clamping element 114 inevitably a movement of the at least one carriage clamping element 114 against the carriage clamping direction F and thus a release of the at least one carriage 102 and thus the at least one fixing device 109 causes.

The at least two Schlittenanpresselemente 119 are preferred, in particular apart from a deflection or curvature, arranged parallel to each other and extend in the axial direction A and substantially in a thereto orthogonal further, for example, third extension direction, which preferably has at least one radial component. Preferably, however, the further, for example third extension direction is slightly curved and each Schlittenanpresselement 119 slightly curved, since the at least two Schlittenanpresselemente 119 constantly under a more or less great bias. This is preferably also independent of a state of the Schlittenlöseschlauchs 121 the case and in particular due to the fact that the space is dimensioned so that the at least two Schlittenanpresselementen 119 never, especially not with completely empty sled-tube 121 , enough space is available to be completely relaxed. The at least one carriage release hose 121 is between the at least two Schlittenanpresselementen 119 arranged and preferably also extends in the axial direction A. The at least two Schlittenanpresselemente 119 are movable by means of at least two connecting elements, in particular pivotable with each other and / or with the base body 71 the at least one rear clamping device 61 and / or with the at least one carriage clamping element 114 connected. The at least one carriage release hose 121 is arranged at least from a preferred axial direction A viewed between the at least two connecting elements.

At least one of the at least two Schlittenanpresselemente 119 and preferably both Schlittenanpresselemente 119 are preferably movable, more preferably pivotally mounted on the body 71 the at least one rear clamping device 61 fastened, more preferably by means of at least one of the at least two connecting elements. The at least two Schlittenanpresselemente 119 are preferably movable, more preferably pivotally mounted on the carriage clamping element 114 fastened, more preferably by means of at least one of the at least two connecting elements. Both sides of the Slide release hose 121 At least one clamping element is a distance from ends of the at least two Schlittenanpresselemente 119 arranged to prevent each other beyond a maximum distance. This causes inflation of the carriage release tube 121 the at least two Schlittenanpresselemente 119 not just swing away from each other, but bulge away from the tube to the outside, since their ends are not each of the ends of the adjacent Schlittenanpresselemente 119 can remove. At least one clip element is preferred by the at least one carriage clamping element 114 educated. At least one clip element is preferred by the main body 71 the at least one rear clamping device 61 educated

Due to the formed curvature shorten the at least two Schlittenanpresselemente 119 however, for example, with respect to a direction of a connector through the carriage release tube 121 to another connector. In particular, a straight-line distance between two ends of one and the same Schlittenanpresselements 119 shortened. As a result, the at least one carriage clamping element moves 114 relative to the main body 71 the at least one rear clamping device 61 and in particular to this and the clamping is solved. For example, the at least two connecting elements are designed as connecting pins that pass through slots of the at least two Schlittenanpresselemente 119 protrude through and at its two ends in each case with the main body 71 the at least one rear clamping device 71 or with the at least one carriage clamping element 114 are connected.

Upon deactivation of the at least one carriage blank 121 causes a restoring force of the at least one front Schlittenanpresselements 119 a movement of the at least one carriage clamping element 114 on the first carriage clamping surface 117 to and thus a jamming of the at least one carriage 102 and the back body 71 and thus the at least one fixing device 109 , Such deactivation of the at least one front carriage blank plate 121 For example, there is a decrease in the pressure inside the carriage release tube 121 , For example, to an ambient pressure, in particular atmospheric pressure. Preferably, this is at least one Schlittenanpresselement 119 and more preferably are the at least two Schlittenanpresselemente 119 at any time under an at least minimum bias, regardless of whether the at least one fixing device 109 is solved or clamped and regardless of where the at least one sled 102 located. In particular, the carriage leaf springs 119 , more preferably, the at least one carriage spring package 119 slightly bent and biased at all times.

The fixing device 109 in the second embodiment is preferably operated such that one in both the at least one front clamping device 21 as well as in the at least one rear clamping device 61 clamped printing form is first stretched by the at least one tensioning drive 104 is activated, for example by the tension hose 104 is pressurized and expands so that it at least one slide 102 emotional. Here is the fixing device 109 first solved, for example by the Schlittenlöseschlauch 121 is pressurized and thereby the two carriage spring assemblies 119 deformed such that the at least one carriage clamping element 114 withdrawn. The at least one sled 102 and thus the entire at least one rear clamping device 61 moves to the at least one front clamping device 21 to. This will cause the around the plate cylinder 07 wound printing form stretched. The at least one sled 102 preferably moves so far until the at least one stop body 111 the at least one rear stop actuator 112 at a stop contact 123 touched and thereby the at least one sled 102 is stopped. The at least one rear stop actuator 112 is preferably already arranged in a position which is an optimal position of the at least one carriage 102 ensured once the at least one stopper body 111 the at least one rear stop actuator 112 touched. Then the fixing device 109 clamped, for example by the pressure in Schlittenlöseschlauch 121 as far as reduced, that the Schlittenfederpakete 119 relax and thereby the at least one carriage clamping element 114 against the first carriage clamping surface 117 press. Once the fixer 109 is clamped, the tensioning drive 104 deactivated, for example by the pressure in the tension hose 104 is reduced, for example, to ambient pressure, in particular atmospheric pressure.

The rear clamping device 61 is thereby held in its position in this state, that the fixing device 109 the at least one sled 102 and thus the at least one rear clamping device 61 in their position in the canal 13 clamps. For this, no drive must remain permanently activated and, in particular, no hose must be permanently pressurized. The at least one tension drive 104 , the at least one sled freezer 121 and that at least one rear actuator 64 are preferred to a same component 71 of the sled 102 and the at least one rear clamping device 62 supported, more preferably against the rear body 71 , Actuations of the at least one tensioning drive 104 , of at least a sledge plate 121 and the at least one rear control element 64 are preferably independently executable.

The exact location of the at least one rear stop actuator element 112 defines the maximum travel of the at least one carriage 102 , Due to the exact location of the at least one rear stop actuator element 112 Thus, a maximum acting on the tensioned pressure form clamping force is set. Preference is given to a plurality, more preferably at least two and even more preferably at least four of the described rear stop actuating elements 112 arranged in the axial direction A spaced from each other. In a preferred embodiment, this is at least one rear stop actuator 112 adjustable in position by means of at least one drive designed as a stop drive. The at least one stop drive is preferably designed as at least one electric motor. The at least one stop drive can also be designed as a pneumatic and / or hydraulic drive.

Alternatively or additionally, a position of the at least one rear stop actuating element 112 manually adjustable.

Preferably, the at least one stop body 111 arranged movably between a stop position and a passing position, preferably in a direction orthogonal to the clamping direction E, for example in the axial direction A. In the stop position, the at least one stop body is located 111 with respect to the clamping direction E with respect to the at least one rear stop actuating element 112 , The interaction then happens as described above. In the passing position is the at least one stop body 111 outside an extension of the at least one rear stop actuator element 112 in the clamping direction E. Solange the at least one stop body 111 is in the passing position limits the at least one stop body 111 ie in particular not the travel of the at least one carriage 102 , This allows a greater travel than the set for clamping operations maximum travel of the at least one carriage 102 , without that at least one rear stop actuator 112 would have to be set differently. This facilitates placing the printing forme on the plate cylinder 07 and thus allows a particularly effective introduction of the printing form in the at least one rear clamping device 61 ,

In a preferred embodiment, the at least one stop body 111 by means of at least one drive designed as a positioning drive in its position adjustable, in particular between the stop position and the passing position movable.

The following is a method for arranging, in particular for clamping and / or clamping the printing plate on the plate cylinder 07 described.

In a first operating state of the plate cylinder, which is also referred to as the initial state 07 There is preferably no printing forme in contact with the at least one tensioning device 101 , The at least one front clamping device 21 and in particular the front clamping gap 27 is preferably closed. The at least one front control element 24 is preferably deactivated. More preferably, the at least one front Klemmlöseschlauch stands 24 under an ambient pressure, in particular atmospheric pressure. The at least one rear clamping device 61 is preferably closed. The at least one rear control element 64 is preferably deactivated. More preferably, the at least one rear Klemmlöseschlauch 64 under an ambient pressure, in particular atmospheric pressure. The at least one sled 102 is preferably with the second channel wall 19 in contact, especially in its peripheral location. Preferably, the at least one rear spacer is located 131 in the retracted position.

In a first method step, which is also referred to as a front opening step, the at least one front clamping device 21 open. For this purpose, the at least one front control element is preferred 24 activated. More preferably, the at least one front clamping release hose 24 subjected to compressed air, which is under a pressure of preferably between 3 bar and 10 bar, more preferably between 5 bar and 7 bar. As a result, the at least one front clamping release hose expands 24 from and relies on the at least one and preferably on the two front pressing elements 23 from. The at least one front contact pressure element 23 bends through and preferably bend the two front pressing elements 23 in the opposite direction. As a result, this becomes at least one radially inner front clamping element 26 from the at least one radially outer front clamping element 22 removed, preferably by 0.9 mm to 1.5 mm, and the front nip 27 will be opened.

A second operating state, the front open operating state of the plate cylinder 07 is preferably distinguished from the first operating state only in that the at least one front clamping device 21 and in particular the front clamping gap 27 is open and that at least one front actuator 24 is activated and more preferably that the at least one front Klemmlöseschlauch 24 under an elevated pressure of preferably between 3 bar and 10 bar, more preferably between 5 bar and 7 bar, and that the at least one front pressing element 23 is more bent.

In a third method step, which is also called the front clamping step, the at least one front clamping device 21 and in particular the front clamping gap 27 closed while the front end of the printing plate in the at least one front clamping device 21 and in particular in the front nip 27 trapped. For this purpose, the at least one front control element is preferred 24 disabled. More preferably, the pressure in the at least one front Klemmlöseschlauch 24 reduced, in particular until the at least one front Klemmlöseschlauch 24 is under an ambient pressure, in particular atmospheric pressure. As a result, the shrinks at least one front Klemmlöseschlauch 24 , The at least one front contact pressure element 23 Uses the space becoming free and stretches and preferably stretch the two front pressing elements 23 and sometimes move towards each other in the opposite direction. As a result, the at least one radially inner front clamping element moves 26 on the at least one radially outer front clamping element 22 to and the front nip 27 will be closed.

A seventh method step, which is also called a clamping step, depends on the embodiment of the fixing device 109 from. The seventh method step becomes associated with the fixing device 109 in the first embodiment, preferably as described below. First, in a first section of the clamping step, the printing forme is preferably prepared by the at least one carriage 102 on the at least one front clamping device 21 and the first channel wall 18 is moved to, more preferably further than it is intended for a printing operation with this printing form. In particular, the at least one carriage is thereby 102 from the second channel wall 19 moved away. For this purpose, the at least one tensioning drive 104 activated. More preferably, the at least one tension hose 104 subjected to compressed air, which is under a pressure of preferably between 3 bar and 10 bar, more preferably between 6 bar and 8 bar. Since the at least one tension hose 104 both on the second channel wall 19 as well as on the at least one sled 102 supported, is thus the at least one slide 102 emotional. The pressure is preferably selected to be higher than that provided in the rear insertion step, because it is necessary to work against the stress that builds up in the printing form. Subsequently, in a second section of the clamping step, the printing plate is relieved again by the at least a sled 102 back to the second channel wall 19 is moved to, more preferably in its peripheral position. This is at least one tension drive 104 disabled. More preferably, the pressure in the at least one tension hose 104 reduced, in particular until the at least one front hose hose 104 is under a lower pressure, for example an ambient pressure, in particular atmospheric pressure.

Following this, in a third section of the clamping step, the at least one slide is preferably again 102 on the at least one front clamping device 21 and the first channel wall 18 to move, more preferably further than intended for a printing operation. This is in turn the at least one tensioning drive 104 activated. More preferably, the at least one tension hose 104 subjected to compressed air, which is under a pressure of preferably between 2 bar and 8 bar, more preferably between 2 bar and 5 bar for a printing plate with a support plate made of aluminum and between 3 bar and 6 bar for a printing plate with a support plate made of steel. Preferably, the printing forme and in particular its rear end remains at least from the beginning of the first section of the clamping step to the end of the third section of the clamping step in the rear clamping device 61 clamped. The at least one sled 102 is initially in an intermediate state closer to the first channel wall 18 and the at least one first clamping device 21 arranged as provided in the printing operation. Now the at least one rear spacer 131 to a position relative to the at least one carriage 102 adjusted, the a certain distance of at least one rear clamping device 61 from the second channel wall 19 specifies that ensures a provided in the printing operation voltage of the printing form. Preference is given to the at least one rear adjusting screw 131 relative to the at least one carriage 102 rotated about its threaded axis, more preferably by means of the at least one as a distance drive 134 trained drive 134 , Following the printing form is relieved again by the at least one slide 102 back to the second channel wall 19 is moved to the at least one rear spacer 131 with the second channel wall 19 at the at least one distance contact point 133 comes into contact. This is at least one tension drive 104 preferably deactivated at least partially. More preferably, the pressure in the at least one tension hose 104 reduced, in particular until the at least one tension hose 104 is under a lower pressure than before, for example under an ambient pressure, in particular atmospheric pressure. The printing form is now stretched and the plate cylinder 07 is in an eighth mode in a first embodiment.

The eighth operating state in the first embodiment, which is also called the clamping state or the pressure operating state, differs when the fixing device is used 109 in the first embodiment of the seventh operating state preferably only in that the at least one carriage 102 from the second channel wall 19 has a greater distance than in the seventh operating state and that the at least one carriage 102 from the first canal wall 18 has a smaller distance than in the seventh operating state and that the at least one rear spacer 131 in its position relative to the at least one carriage 102 is changed so that the at least one rear spacer 131 with respect to the circumferential direction D relative to the at least one carriage 102 continue towards the back canal wall 19 is arranged to than in the seventh operating state and that the printing forme on the lateral surface 124 of the plate cylinder 07 is curious. In this eighth operating state is the plate cylinder 07 ready for a printing operation and / or the plate cylinder is in the printing operation.

The seventh method step, which is also called the clamping step, in contrast, in connection with the fixing device 109 in the second embodiment, preferably as described below. First, in a first section of the clamping step, the printing forme is preferably prepared by the at least one carriage 102 on the at least one front clamping device 21 and the first channel wall 18 is moved to, more preferably further than it is intended for a printing operation. In particular, the at least one carriage is thereby 102 from the second channel wall 19 moved away. For this purpose, the fixing device is preferably first 109 solved by the at least one, preferably as Schlittenlöseantrieb 116 trained drive 116 is activated. For this example, the pressure in Schlittenlöseschlauch 121 is increased so far that the carriage spring assemblies 119 deform and thereby the at least one carriage clamping element 114 from the first carriage clamping surface 117 solves. Preferably, the at least one stop body 111 moved to its passing position to the movements of the at least one carriage described below 102 to facilitate, more preferably by means of at least one designed as a positioning drive. Now the at least one tension drive 104 activated. More preferably, the at least one tension hose 104 subjected to compressed air, which is under a pressure of preferably between 3 bar and 10 bar, more preferably between 6 bar and 8 bar. Since the at least one tension hose 104 both on the second channel wall 19 as well as on the at least one sled 102 supported, is thus the at least one slide 102 emotional. The pressure is preferably chosen higher than in the rear inserting step provided because it must be worked against the stress building up in the printing form.

Following in a second section of the clamping step, the printing plate is relieved again by the at least one carriage 102 back to the second channel wall 19 is moved to, more preferably in its peripheral position. This is at least one tension drive 104 disabled. More preferably, the pressure in the at least one tension hose 104 reduced, in particular until the at least one front hose hose 104 is under a lower pressure, for example an ambient pressure, in particular atmospheric pressure. Then it is preferred first of the at least one stop body 111 moved into the stop position, more preferably by means of at least one designed as a positioning drive. Before and / or after and / or at the same time, this becomes at least one rear stop actuating element 112 with respect to the clamping direction E preferred relative to the cylinder barrel 12 moved in a Anschlagungsolllage, more preferably by means of at least one drive designed as a stop drive. Further preferred is the at least one rear stop screw 112 turned around its thread axis.

Now, in a third section of the clamping step, the at least one slide is again preferred 102 on the at least one front clamping device 21 and the first channel wall 18 to and in particular from the second channel wall 19 away moves to the at least one rear stop actuator 112 the at least one stop body 111 touched. A continuation of the movement of the at least one sled 102 is then because of the contact of the at least one rear stop actuator 112 with the at least one stop body 111 not possible. This is in turn the at least one tensioning drive 104 activated. More preferably, the at least one tension hose 104 subjected to compressed air, which is under a pressure of preferably between 2 bar and 8 bar, more preferably between 2 bar and 5 bar for a printing plate with a support plate made of aluminum and between 3 bar and 6 bar for a printing plate with a support plate made of steel.

Preferably, the printing forme and in particular its rear end remains at least from the beginning of the first section of the clamping step to the end of the third section of the clamping step in the rear clamping device 61 clamped.

Following is the fixing device 109 clamped, for example by the pressure in Schlittenlöseschlauch 121 as far as reduced, that the Schlittenfederpakete 119 relax and thereby the at least one carriage clamping element 114 against the first carriage clamping surface 117 press, for example, to ambient pressure, in particular atmospheric pressure. Once the fixer 109 is clamped, the tensioning drive 104 deactivated, for example by the pressure in the tension hose 104 is reduced, for example, to ambient pressure, in particular atmospheric pressure. The rear clamping device 61 is thereby held in its position in this state, that the fixing device 109 the at least one sled 102 and thus the at least one rear clamping device 61 in their position in the at least one channel 13 clamps. The printing form is now stretched and the plate cylinder 07 is in an eighth mode in a second embodiment.

In this eighth operating state is the plate cylinder 07 ready for a printing operation and / or the plate cylinder is in the printing operation.

Is preferred regardless of the embodiment of the fixing device 109 carried out in at least one eighth step, at least one proof. A copy of a printed product, such as a bow 09 , is printed for this proof. On the basis of the resulting print image is evaluated whether and how far the plate tension should be changed and / or if and how far an oblique position of the printing plate on the forme cylinder 07 should be changed and / or whether and how far a convex and / or concave deformation of the front end of the printing plate should be changed. If the print image is already perfect, all settings of the clamping device 101 maintained. This process is preferably repeated as many times as necessary. More preferably, no more than this one proof is necessary to complete and final adjustment of the plate cylinder 07 and even more preferably all with a common transfer cylinder 06 cooperating plate cylinder 07 set.

Otherwise, in at least a ninth method step adjustments of the settings of the clamping device 101 carried out according to the evaluation in the eighth step. Regardless of the type of adjustments, the fixer will first be used 109 solved again and the printing form at least partially relaxed.

When using the first embodiment of the fixing device 109 in the ninth step of the process, the at least one slide is first of all 102 again from the second channel wall 19 away and onto the first canal wall 18 and the at least one front clamping device 21 too moved. The at least one tensioning drive is preferred for this purpose 104 activated. More preferably, the at least one tension hose 104 acted upon by compressed air, which is under a pressure of preferably between 3 bar and 10 bar, to the at least one carriage 102 performs the said movement. Then the at least one sled 102 stopped. Now the at least one rear spacer 131 to a position relative to the at least one carriage 102 adjusted, the closer spacing of the at least one rear clamping device 61 wall of the second channel 19 allowed. Preference is given to the at least one rear adjusting screw 131 relative to the at least one carriage 102 rotated about its threaded axis, more preferably by means of the at least one distance drive 134 , Following the printing form is relieved again by the at least one slide 102 back to the second channel wall 19 is moved to, preferably until the at least one carriage 102 is again in its peripheral position and / or until the at least one rear spacer 131 with the second channel wall 19 at the at least one distance contact point 133 comes into contact. This is at least one tension drive 104 preferably deactivated at least partially. More preferably, the pressure in the at least one tension hose 104 reduced, in particular until the at least one tension hose 104 is under a lower pressure than before, for example under an ambient pressure, in particular atmospheric pressure.

When using the second embodiment of the fixing device 109 In the ninth method step, the at least one tensioning drive is preferred 104 activated. More preferably, the at least one tension hose 104 subjected to compressed air, which is under a pressure of preferably between 3 bar and 10 bar. The at least one sled 102 and in particular the at least one rear stop actuator 112 is now from the at least one tensioning drive 104 with sufficient force against the at least one stop body 111 pressed. Now, the fixing device is preferred first 109 solved, for example by the pressure in Schlittenlöseschlauch 121 is increased so far that the carriage spring assemblies 119 deform and thereby the at least one carriage clamping element 114 from the first carriage clamping surface 117 solves. Following the printing form is relieved again by the at least one slide 102 back to the second channel wall 19 is moved to, preferably until the at least one carriage 102 is again in its peripheral position and / or until the at least one rear spacer 131 with the second channel wall 19 at the at least one distance contact point 133 comes into contact. This is at least one tension drive 104 preferably deactivated at least partially. More preferably, the pressure in the at least one tension hose 104 reduced, in particular until the at least one tension hose 104 is under a lower pressure than before, for example under an ambient pressure, in particular atmospheric pressure.

Regardless of the embodiment of the fixing device 109 Then one or more of the following sub-steps are performed.

In a sub-step for correcting an inclined position of the printing forme and / or in a sub-step for correcting a convex and / or concave deformation of the front end of the printing plate, at least one of the at least two and preferably the at least two second supporting points will be used 34 ; 36 set. For this purpose, the at least two are preferred as the front adjusting screws 39 ; 41 trained front contact body 39 ; 41 in their position relative to the at least one front clamping device 21 , in particular to the at least one radially outer front clamping element 22 set. Further preferred is at least one and in particular the at least two front set screws 39 ; 41 about its threaded axis relative to the at least one front clamping device 21 rotated, more preferably by means of at least one as a front biasing drive 43 ; 44 trained drive 43 ; 44 , Because preferred at any time at all support points 33 ; 34 ; 36 the first channel wall 18 and the at least one front clamping device 21 , in particular the at least one radially outer front clamping element 22 , in particular in the form of the bulge and the at least two front contact body 39 ; 41 are in contact with each other, by adjusting the at least two second support points 33 ; 34 a deflection and / or an inclined position of the at least one first clamping device 21 relative to the first channel wall 18 affected.

For example, the at least two front screws 39 ; 41 at their setting relative to the bulge of the at least one first clamping device 21 from the first canal wall 18 moved away, so form the first channel wall 18 facing ends of the at least two front screws 39 ; 41 together with the preferably with respect to the axial direction A arranged therebetween bulge no straight line. By acting forces, for example because of as a spring 107 trained support body 107 and / or the tensioned printing plate, then at least the at least one front clamping device 21 deformed such that axially outer portions of the at least one front clamping device 21 and the clamped pressure form stronger to the first channel wall 18 are drawn as an axially middle region of the at least one first clamping device 21 and the clamped printing form. The spanned printing form is thus deformed convexly at its front end. Such a convex deformation at the front end of the printing form preferably propagates through the entire printing form in the circumferential direction D and is further preferably adjusted so that it counteracts a concave deformation of the printed image on the printing form.

For example, the at least two front screws 39 ; 41 at their setting relative to the bulge of the at least one first clamping device 21 on the first canal wall 18 moved to, so form the first channel wall 18 facing ends of the at least two front screws 39 ; 41 together with the preferably with respect to the axial direction A arranged therebetween bulge no straight line. By acting forces, for example because of as a spring 107 trained support body 107 and / or the tensioned printing plate, then at least the at least one front clamping device 21 deformed such that axially outer portions of the at least one front clamping device 21 and the clamped pressure form less strong to the first channel wall 18 are drawn as an axially middle region of the at least one first clamping device 21 and the clamped printing form. The spanned printing form is thus deformed concave at its front end. Such a concave deformation at the front end of the printing form preferably propagates through the entire printing form in the circumferential direction D and is further preferably adjusted so that it counteracts a convex deformation of the printed image on the printing form.

For example, the at least two front screws 39 ; 41 at their setting relative to the bulge of the at least one first clamping device 21 moved in opposite directions, so form the first channel wall 18 facing ends of the at least two front screws 39 ; 41 together with the preferably arranged with respect to the axial direction A between the bulge further a straight line, which is, however, oriented obliquely relative to the front clamping gap. By acting forces, for example because of as a spring 107 trained support body 107 and / or the tensioned printing form, then becomes the at least one front clamping device 21 preferably together with the clamped printing form to the front channel wall 18 pressed that at least one front clamping device 21 preferably together with the clamped pressure form relative to the front channel wall 18 preferably rotates about a substantially radial alignment axis. This alignment axis preferably passes through the first support point 33 , This happens in particular because a first axially outer region of the at least one front clamping device 21 and the clamped printing form on to the first channel wall 18 as a second axially outer region of the at least one front clamping device 21 and the unfolded printing form located on another axial side of the first support point 33 is located as the first axially outer region. For example, the first axially outer region of the side I is assigned and the second axially outer region of the side II is assigned. The spanned printing form is thus at its front end obliquely on the plate cylinder 07 hung up. Such an oblique position of the printing form preferably propagates through the entire printing form in the circumferential direction D and is further preferably adjusted so that it counteracts an inclined position of the printed image on the printing form.

If necessary, that is, in particular with correspondingly deformed printed image on the printing plate, the at least two front set screws 39 ; 41 adjusted so that in superposition of the effects described above, a mixture of a skew of the printing plate on the plate cylinder 07 on the one hand and a convex and / or concave deformation of the printing forme on the other hand results.

An inclination of the printing form by means of the at least one front clamping device 21 optionally also requires a compensating inclination and a movement in the axial direction A of the at least one, by the at least one rear clamping device 61 carriage connected to the pressure plate 102 and / or the at least one rear clamping device 61 itself. Due to the flexible storage and / or anchoring of the at least one carriage 102 and / or the at least one rear clamping device 61 on the one hand and by the at least one Seiteneinstellvorrichtung 144 , in particular the at least one as axial drive 141 trained drive 141 on the other hand, is the at least one rear clamping device 61 and more preferably, the at least one carriage 102 adjustable in position in the axial direction A. A maximum offset of the at least one carriage 102 and the at least one rear clamping device 61 in the axial direction A, in particular from the end position to the end position preferably between 1 mm and 10 mm, more preferably between 3 mm and 6 mm.

A sub-step for correcting the plate tension, depending on the embodiment of the fixing device 109 carried out analogously to the respective seventh method step. However, on the one hand, preference is given to dispense with the first clamping and subsequent relieving of the printing form on the one hand and, on the other hand, depending on the embodiment of the fixing device 109 the at least one rear stop actuator 112 or the at least one rear spacer 131 is adjusted according to the desired new plate tension. If the plate tension has assumed the ideal value already in the trial printing in the eighth method step, the seventh method step for tensioning the printing plate is preferably carried out again as described above, but using the previously used settings of the at least one rear stop actuating element 112 or the at least one rear spacer 131 , An advantage of re-tensioning the printing form is, for example, that reproducible conditions prevail and the plate tension can be adjusted uniformly over the entire extent of the printing plate. Therefore, the printing for any adjustment of at least two front set screws 39 ; 41 and / or the at least one rear stop actuating element 112 or the at least one rear spacer 131 completely re-tensioned.

For a correction of a circumferential register error and / or a page register error, one on a cylinder pin is preferred 17 of the plate cylinder 07 arranged circumferential register adjustment and / or side register adjustment used. The printing form itself remains unchanged in such settings of the circumferential register and / or the side register on the plate cylinder 07 clamped.

Preferably, the method runs for clamping and / or clamping the printing plate on the plate cylinder 07 machine-controlled. For this purpose, all drives are preferred 43 ; 44 ; 104 ; 116 ; 134 ; 141 , in particular the at least one front pretensioning drive 43 ; 44 and / or the at least one tensioning drive 104 and / or the at least one carriage release drive 116 and / or the at least one distance drive 134 and / or the at least one axial drive 141 and / or the at least one stop drive connected to the machine control and / or controlled by the machine control and / or controllable and more preferably regulated and / or controlled by the machine control. The at least one front adjusting element are also preferred 24 and / or the at least one rear adjusting element 64 connected to the machine control and / or controlled by the machine control and / or controllable and more preferably regulated and / or controlled by the machine control. In the case of tensioning drives designed as hoses 104 and / or actuators 24 ; 64 and / or carriage release hoses 121 There is a control and / or regulation by means of the machine control preferably in a control and / or regulation of the pressure prevailing therein by means of the machine control.
