Description

The invention relates to a method for arranging each at least one printing plate on at least two plate cylinders of a printing press.

In printing presses, for example, forme cylinders are used which are designed as plate cylinders and carry printing plates in the form of printing plates. These printing plates can be replaced. For this purpose, a device is necessary, which fixes the pressure plate releasably attached to the forme cylinder. With increasing demands on the precision of the printed products produced with the printing press, the demands placed on the precision with which the printing plate is arranged on the forme cylinder also increase. For example, in value printing demands are made, which requires a precision of the position of the printing plates at least relative to each other in the range of micrometers. Such accuracies are not achievable with Plattenklemmungen conventional sheetfed presses.

By the DE 41 29 831 A1 and the DE 195 11 956 A1 in each case a plate cylinder is known, wherein the plate cylinder has a channel in which a clamping device is arranged, which has a radially outer clamping element which is immovably disposed relative to a base body of the clamping device and wherein the clamping device comprises a pressing element, which arranged radially further inside is, as the radially outer clamping element and wherein the clamping device comprises an actuating element, by means of which the pressing element is at least partially movable relative to the radially outer clamping element at least in and / or against a clamping direction.

By the DE 41 29 831 A1 It is furthermore known that the clamping device has a radially inner clamping element which is always held in a defined position with respect to a circumferential direction by means of at least one front pressing element.

By the WO 93/03925 A1 there is known a plate cylinder having a channel in which a tensioning device is arranged which has a clamping device movable on a carriage within the channel.

By the DE 42 39 089 A1 , the EP 0 579 017 A1 and the EP 0 711 664 A1 Methods and apparatus for clamping and register correction of printing plates are known.

By the DE 42 35 393 A1 For example, a register setting device and a method for register adjustment are known, register marks being used.

By the DE 10 2007 057 455 A1 a device is known in which a printing plate lying on a plate cylinder can be deformed. For adjustment of the printing plate in the circumferential direction already performed adjustments of the printing plate in the axial direction are initially reversed.

By the US 2006/0174792 A1 For example, a method is known in which an ink-jet printhead is deformed by thermal expansion to respond to a change in width of a sheet-shaped plastic substrate.

By the DE 20 35 278 A a method for arranging each at least one printing plate on at least two plate cylinders of a printing machine is known, wherein the at least two plate cylinders each have at least one channel, in each of which at least one clamping device is arranged, each having at least one front clamping device, in which a front end a respective pressure plate is clamped and in each case has at least one rear clamping device, in which a rear end of this respective pressure plate is clamped.

ISBN 3-540-66941-8 discloses a method in which at least one register pattern of a printing material is detected in an inspection process by means of at least one register sensor and at least implicitly depending on it in an evaluation process new settings for at least one adjustment at least one the tensioning devices are calculated. Corrections of a circumferential register are made by rotating die cylinders.

The invention has for its object to provide a method for arranging each at least one printing plate on at least two plate cylinders of a printing machine, with a high degree of precision and reproducibility of the position of the printing plates is possible in a simple manner.

The object is achieved by the features of claim 1.

The achievable with the present invention consist in particular in that a laying a printing plate on a form of a plate cylinder form cylinder is simple and can be performed with high precision. Also, a high reproducibility of the position of the printing plate on the plate cylinder is advantageous. In particular, in printing machines in which several form cylinder interact with a common transfer cylinder, results the advantage of a particularly high precision, since only one point is present at which the substrate is provided with printing ink and therefore the precision of the printed image depends exclusively on the precision of the position of the printing inks on the common transfer cylinder and thus ultimately on the precision, with which the printing plates are arranged on the forme cylinders and with which the forme cylinders are arranged relative to one another.

Preferably, a plate cylinder, in particular a plate cylinder of a printing press, which preferably has at least one channel in which preferably at least one clamping device is arranged, wherein the at least one clamping device preferably at least one radially outer clamping element, in particular at least one radially outer terminal strip, which or which is preferably arranged immovably relative to a base body of the at least one clamping device, wherein preferably the at least one clamping device has at least one pressing element which is arranged radially further inward than the at least one radially outer clamping element and wherein preferably the at least one clamping device at least one Actuating element, by means of which the at least one pressing element at least partially relative to the at least one radially outer clamping element and more preferably relative to a cylindrical bale of the plate cylinder at least in and / or opposite n a clamping direction is movable, one or more of the features described below.

However, a force to be expended by the actuating element is just as great, because instead a travel of the at least one actuating element is doubled, since the at least one actuating element arranged between the at least two pressing elements can each move on both pressing elements. If a release hose, in particular Klemmlöseschlauch is used as an actuating element, no higher pressure must therefore be achievable or achieved for a doubled force in the Klemmlöseschlauch, as with only one pressing.

Preferably, at least one rectilinear connecting line between the at least two pressing elements of the at least one clamping device intersects the at least one actuating element of this at least one clamping device.

Preferably, in the at least partial relaxation of the at least one pressure plate, a compressive force acting on this pressure plate is reduced by preferably at least 50%, more preferably at least 75% and even more preferably at least 90%. Preferably, when the at least one pressure plate is completely relaxed, a clamping force acting on this pressure plate is reduced by 100%.

The new settings for the at least one adjustment element are preferably determined by means of a computer, more preferably the machine control or a computer connected in circuit technology with the machine control, and further preferably calculated. The at least one register sensor is preferably designed as at least one optical register sensor, for example an area camera. Preferably, the at least one register sensor is connected in terms of circuitry to the machine control.

Preferably, the method is characterized in that the printing material has at least one register pattern which has at least two reference elements, in particular register marks, which originate from different printing plates and are preferably printed with different printing inks and that preferably with respect to each register pattern a reference element, in particular a register mark , is defined as the base reference element, in particular the base register mark, and that in the inspection process actual positions relative to target positions of all reference elements, in particular register marks of the at least one register pattern preferably relative to the base reference element, in particular the base register mark of the respective at least one register pattern are further preferred by the at least a register sensor are detected.

Preferably, the method is characterized in that in the case of at least one occurring in the circumferential direction, exceeding a tolerance range deviation of a position relative to a desired position in the evaluation process and preferably taking into account further detected register pattern new settings for at least one adjustment of those at least one Tensioning device can be determined and preferably calculated, in which the at least one pressure plate is, for example erroneously tensioned or was, which has caused at least one circumferentially deviating register mark and in a first fitting at least this at least one example erroneously tensioned pressure plate at least with respect to the circumferential direction at least partially and more preferably fully relaxed and then changed clamped in the circumferential direction on the respective plate cylinder.

Preferably, the method is characterized in that in the evaluation process new settings for at least one adjustment at least two and more preferably all fixtures are determined and further preferably calculated in each of which at least one pressure plate is, for example erroneously tensioned or was and in the first fitting process at least these at least two and preferably all For example, erroneously tensioned pressure plates at least partially and more preferably completely relaxed at least with respect to the respective circumferential direction and remain clamped in the respective at least one front clamping device and the respective at least one rear clamping device in particular the respective at least one clamping device and then preferably by means of the respective at least one Clamping device according to the newly determined, preferably calculated settings for the respective at least one adjustment changed in the circumferential direction on the respective plate cylinder are clamped.

Preferably, the method is characterized in that in the evaluation process, the new settings for a plurality of adjusting elements of one or more clamping devices at the same time and / or taking into account mutual influences of the plurality of adjusting elements are determined and preferably calculated.

Preferably, the method is characterized in that the first fitting process of at least two, for example, incorrectly tensioned printing plates at least temporarily takes place simultaneously.

Preferably, the method is characterized in that at least two register patterns are printed on the substrate in at least one of the inspection process preceding test printing, which are composed of at least two of at least two different printing plates derived reference elements and in particular register marks. In particular, their printing ink was thus transferred from different printing plates directly or preferably indirectly to the printing substrate.

Preferably, the method is characterized in that in the first fitting process, a voltage within the at least one pressure plate with respect to the axial direction remains unchanged.

Preferably, the method is characterized in that the at least one adjusting element of the at least one clamping device is designed as at least one front contact body, by means of which a distance of the at least one front clamping device from the first channel wall of the at least one channel is adjustable and / or that at least an adjusting element of the at least one tensioning device is designed as at least one rear spacer, by means of which a distance of the at least one rear clamping device from the second channel wall of the at least one channel is adjustable and / or that the at least one adjusting element of the at least one clamping device is designed as at least one axial drive is, by means of which a position of the at least one rear clamping device with respect to the axial direction is adjustable parallel to a rotation axis of the respective plate cylinder.

Preferably, the method is characterized in that at least two arranged on opposite surfaces of the substrate register pattern in the inspection process preferably by mutually mechanically and / or circuitry coupled sensors, in particular register sensors and / or detected simultaneously and processed together in the evaluation process. The simultaneous detection offers the advantage that this ensures that the printing material can not have been moved between detecting a front side and detecting a rear side. Since the position of the at least two sensors is preferably known and / or constant with respect to each other, precise data can be obtained therefrom via the register of front side and rear side. Preferably, detection areas of the at least two register sensors face each other. Further preferably, the printing material is arranged between the at least two register sensors when detecting the at least two simultaneously registered register marks. Joint processing offers the advantage that mutual influences can be taken into account. For example, a changed setting of a front adjustment element may require a changed setting of a rear adjustment element which initially appears to be already perfectly adjusted. This applies both to a printed image on the front side of the printing material relative to a printed image on the back of the printing substrate, as well as different partial printing images on a common side of the printing substrate.

Preferably, the method is characterized in that a number of registered register patterns evaluated and taken into consideration are at least as large as a sum of setting elements of at least two plate cylinders designed as front contact bodies and / or rear spacers. More preferably, this number is at least eight per printing plate, more preferably at least fourteen per printing plate. In particular, register patterns are preferred recorded and evaluated both a front and a back of the substrate.

Preferably, the method is characterized in that, especially in the case of at least one with respect to a rotation axis of the at least one forme cylinder occurring in the axial direction, exceeding a tolerance range deviation of an actual position relative to a desired position in the evaluation preferably taking into account further registered register pattern new Settings for at least one temperature of at least one, for example, in its axial extent faulty, arranged on the at least one plate cylinder pressure plate and / or at least one cylinder bale of the at least one plate cylinder and / or at least one cooperating with this pressure plate and / or this at least one plate cylinder temperature control, in particular Temperierfluids determined and preferably calculated and in a second fitting process, the at least one temperature of at least one pressure plate and / or this at least one cylinder bale and / or this temperature control, in particular tempering according to the new settings is changed. This is due to the fact that in cases where one compares multiple register patterns arranged at different axial positions and in which a particular ink is axially different than the other inks, this error can be compensated for with temperature if it is is not a recoverable by means of conventional side register devices error, such as a constant axial displacement of the pressure plate and / or the plate cylinder. An advantage is in particular that thereby a uniform change of a width of the corresponding print image at least the corresponding ink can be achieved, in particular independent of a position of the printing form in the circumferential direction and in particular over an entire print image length and in particular independent of the printed images of the remaining printing inks. Preferably, the at least one tempering fluid is at least one tempering liquid, for example substantially water, optionally with additives such as rust inhibitors or the like.

Preferably, the method is characterized in that in the evaluation at least one temperature of at least one further pressure plate and / or at least one temperature of a cylinder bale of at least one further plate cylinder and / or at least one temperature of at least one temperature control, for example tempering of another plate cylinder and / or a Ambient temperature of the printing press and / or a temperature of the printing material in the determination and preferably calculation of the new settings for the at least one temperature of at least one defective, for example, in its axial extent pressure plate and / or the at least one cylinder bale and / or the temperature control.

The new settings for the at least one temperature are preferably determined by means of a computer, more preferably the machine control or a computer connected in circuit technology with the machine control, in particular calculated. However, it is also possible in principle that these new settings are determined by an operator, for example by calculation and / or with the aid of predetermined setting constellations, for example value tables.

Preferably, the method is characterized in that after the adjustment process, a temperature difference between two different printing plates, which are arranged on different plate cylinders, is greater or smaller than before the fitting process.

Preferably, the method is characterized in that in the inspection process at least two register patterns are detected, each having at least one originating from a same printing plate reference element, in particular at least one derived from a same printing plate register mark.

Preferably, the method is characterized in that in the evaluation process preferably taking into account further registered register pattern new settings for at least two, more preferably all, for example, in their axial extent faulty printing plates are determined and preferably calculated and in the second fitting process, the at least one Temperature of these pressure plates and / or respective cylindrical bales of the respective plate cylinder and / or temperature control are changed according to the new settings.

Preferably, the method is characterized in that in the second fitting operation, a tension within the at least one pressure plate with respect to a circumferential direction is maintained unchanged. Since an angular position of pixels, in particular in the case of a temperature-dependent change of dimensions of the corresponding printing plate, does not depend on the temperature, it is not necessary to make any adjustments after the temperature change that affect the angular position and / or circumferential direction D.

Preferably, the method is characterized in that the setting of the at least one Setting element and more preferably all newly adjusted adjusting machine-controlled and made by means of at least one corresponding drive. In particular, in combination with the detection of the at least one register pattern by means of the at least one sensor, in particular register sensor thus preferably results in an automated and autonomous ablauf capable method for arranging the at least one pressure plate on the at least one plate cylinder.

Preferably, the method is characterized in that the at least one pressure plate is at least partially and more preferably fully relaxed at least with respect to the circumferential direction by at least one carriage supporting the at least one rear clamping device along a tensioning path of the at least one disposed in the same channel front Clamping device is removed and / or that at least one pressure plate is clamped changed by at least one at least one rear clamping device carrying carriage along a clamping path to the at least one, disposed in the same channel front clamping device is moved to after at least one adjustment again was set.

Preferably, the method is characterized in that the at least one pressure plate is tensioned changed by first the at least one carriage is moved together with the clamped in the at least one rear clamping device rear end of the pressure plate on the at least one front clamping device and the first channel wall and in that thereafter at least one rear spacer is adjusted to a position relative to the at least one carriage and / or relative to a cylindrical bale of the at least one plate cylinder which at least in a region of said at least one rear spacer has a given distance from the at least one rear clamping device second channel wall independently defines a tensioning drive and that subsequently the tensioning drive is deactivated and the at least one carriage together with the at least one rear clamping device is thereby held in its position along the tensioning path that a force exerted by the tensioned pressure plate presses the at least one slide over the at least one rear spacer against the second channel wall. In one possible mode of operation, at least two rear adjusting elements are changed in their position relative to the at least one slide and / or relative to the second channel wall to different degrees. As a result, the at least one rear clamping device and in particular its at least one radially inner and / or its at least one radially outer clamping element is preferably elastically deformed in itself, preferably in the circumferential direction. As a result, as viewed along its axial extent, the printing form is tensioned to a different extent in the circumferential direction and deformed accordingly. Thus, for example, convex and / or concave errors in the arrangement of printed images can be adapted to printing plates.

Preferably, the method is characterized in that each setting element is associated with exactly one, in its position with respect to the axial direction with this respective adjustment at least partially matching register pattern. Then it is possible to deduce relatively easily and directly from the register patterns necessary new settings of the setting elements. Alternatively, for example, if the substrate is too narrow in printing machines with a variable substrate width, settings of the adjustment elements are determined from positions of a plurality of register patterns, preferably calculated. In particular, this is necessary if as preferred substrates with very different widths, for example with widths between 400 mm and 900 mm are used.

Preferably, in a front opening operation, the at least one front clamping device is opened. Preferably, a front end of the pressure plate is inserted into a front clamping gap of the at least one front clamping device in a front loading operation. Preferably, in a front clamping operation, the at least one front clamping device is closed and in the process the front end of the pressure plate is clamped in the at least one front clamping device. Preferably, the printing plate is then placed in a support operation on a lateral surface of the plate cylinder.

Preferably, in a rear opening operation, the at least one rear clamping device is opened and before and / or simultaneously and / or thereafter the at least one carriage along the clamping path from an edge position or spaced edge position to an insertion distance to the at least one front clamping device and the first channel wall to a central or internal situation moves. The spaced-apart edge layer is preferably a layer in which the at least one carriage is arranged at a distance of a defined reserve distance, for example between 4 mm and 6 mm, from the second channel wall. This reserve route serves to increase a potential tension travel. The term central position serves to distinguish between the peripheral position and / or the spaced edge position and in particular does not mean that the situation must be exactly in the middle. Preferably, in a rear loading operation, a rear end of the printing plate, which has meanwhile been placed around the plate cylinder, laid on the plate cylinder so that it is at least one Component protrudes in the circumferential direction via a second channel wall with the lateral surface of the plate cylinder connecting edge and then the at least one carriage along the clamping path from its central or inner layer to the insertion path to the second channel wall moves to its edge position or ebvorzugt its spaced edge position. Preferably, the rear end of the pressure plate is at least partially enclosed by at least one rear nip of the at least one rear clamping device, while the at least one carriage along the clamping path from its central or inner position on the second channel wall is moved to its edge position or its spaced edge position. The term "enclose" is understood here to mean that at least one straight-line connection of at least one radially inner clamping element of the at least one rear clamping device with at least one radially outer clamping element of the at least one rear clamping device intersects the rear end of the pressure plate. Preferably, in a rear clamping operation, the at least one rear clamping device is closed while the rear end of the pressure plate is clamped in the at least one rear clamping device.

Preferably, in a tensioning operation, the at least one carriage is moved along the tensioning path toward the at least one front clamping device and the first channel wall, and the pressure plate is thereby tensioned. Preferably, in a first section of a clamping operation, the at least one carriage is moved along the clamping path toward the at least one front clamping device and the first channel wall. Preferably, the pressure plate is tensioned with a first force. Preferably, the printing plate is stretched with stronger than it is provided for a printing operation with this pressure plate. Preferably, in a second portion of the clamping operation, the pressure plate is relieved again by the at least one carriage is moved back to the second channel wall. Preferably, in a third section of the clamping operation, the at least one carriage is again moved toward the at least one front clamping device and the first channel wall. Preferably, the pressure plate is tensioned with a second force. Preferably, the first force is the same size as the second force. Preferably, the pressure plate remains clamped at least from the beginning of the first portion of the clamping operation to the end of the third portion of the clamping operation in the rear clamping device. Depending on the embodiment of the preferably used at least one rear clamping device, one of the two embodiments of the clamping operation described below is preferably used.

In a first embodiment of the clamping operation and in particular of the third section of the clamping operation, the at least one carriage is preferably initially coupled to the at least one front clamping device and the first channel wall by means of the at least one tensioning drive together with the rear end of the pressure plate clamped in the at least one rear clamping device is moved and is thereafter preferably at least one rear spacer, which is preferably part of the at least one carriage, set to a position relative to the at least one carriage, which determines a certain distance of the at least one rear clamping device of the second channel wall independently of the at least one tensioning drive , and after the at least one tensioning drive is deactivated, the at least one carriage, together with the at least one rear clamping device, is held in its position along the tensioning path in that one of the tensioned Dru Back plate exerted force presses the at least one slide over the at least one rear spacer against the second channel wall. Preferably, at least after deactivation of the at least one tensioning drive, the at least one rear spacer is in contact with the second channel wall and at the same time with the at least one carriage and thereby determines the distance of the at least one rear clamping device from the second channel wall independently of the at least one tensioning drive.

In a second embodiment of the clamping operation is preferably at least one, preferably in a fixedly mounted relative to the cylindrical ball bearings, rear stop actuator moved relative to the cylindrical bale in a Anschlagungsolllage and is then preferably the at least one carriage by means of at least one tensioning drive together with the in the at least one rear clamping device clamped rear end of the pressure plate on the at least one front clamping device and the first channel wall moves until the at least one rear stop actuator touches at least one stop body and is then preferably clamped at least one fixing and holds these at least one fixing preferably at least one carriage is in its position, for example, by a pressure in a carriage release tube designed as a carriage release plate is reduced and preferably so far that sled spring packages en span and thereby preferably at least one carriage clamping element is pressed against a first carriage clamping surface and then preferably the at least one tensioning drive is deactivated, for example by a pressure in a tensioning tube designed as a tensioning drive is reduced, for example, to ambient pressure.

Advantages of this plate cylinder and / or this method consist for example in that preferably a tensioning drive also used can be brought into a position such that a laying of the rear end of the pressure plate is facilitated and in particular in a substantially radial direction and without manual threading of the pressure plate in the rear clamping device is made possible, since preferably the rear clamping device is moved so in that it surrounds the rear end of the pressure plate, wherein nevertheless the radially outer clamping element is immovable relative to the slide and thus a particularly stable clamping can be achieved.

Another advantage of a preferred embodiment of the plate cylinder and / or the method is, for example, that in a clamped and / or tensioned state of the pressure plate no drive a clamping device or clamping device must be activated.

Another advantage is that with repeated application of the method with the same or a different printing plate very precisely reproducible results of the position and tension of the printing plate can be achieved.

The at least one data input is preferably connected in circuit technology to the at least one register sensor. The at least one register sensor is preferably designed as at least one area camera.

Preferably, the method and / or the system for register control and / or the tensioning device is based on the principle that the corresponding printing forme is first clamped on the forme cylinder and prepared by being once stretched and relaxed again and then that the printing plate by means of at least a slide is acted upon by a first clamping force which causes an expansion of the printing plate and thus the printed image and that then a minimal reduction of the clamping force to a second clamping force, in which the pressure plate initially remains taut to carry out a trial print. If it turns out that changes are to be made, the pressure plate is first at least partially and preferably fully relaxed and then acted upon by means of the at least one carriage with a newly determined third clamping force, which causes a change in elongation of the printing plate and the printed image. This is followed, in turn, by a minimal reduction of the clamping force to a fourth clamping force, in which preferably a printing operation is carried out. Preferably, a difference between the first clamping force and the second clamping force is significantly smaller than a difference between the first clamping force and the third clamping force.

A sheet-fed rotary printing machine 01 with a printing unit 02 with several printing units 08 is also exemplary in 1 shown. For example, the printing press has 01 at least one printing unit 08 and at least one dryer, each on the substrate 09 acting along a transport path of the printing substrate 09 before transfer cylinders described below 06 are arranged.

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 plate cylinder 07 and more preferably several, for example four plate cylinders 07 in rolling contact. The printing unit is preferred 02 as a multi-color printing unit 02 educated. Each of these plate cylinders 07 is preferably associated with at least one inking unit. Preference is given to the at least one plate cylinder 07 at least one printing form 73 in the form of at least one and preferably exactly one printing plate 73 arranged. Preferred is on each plate cylinder 07 exactly one printing plate 73 arranged or provided, whose extension in an axial direction A of the plate cylinder 07 preferably at least 75% and more preferably at least 90% of an expansion of a cylindrical bale 12 of the at least one plate cylinder 07 in this axial direction A corresponds.

This is the corresponding plate cylinder 07 for maintenance and in particular for a pressure plate change accessible. Further preferred are the inking units all with a common transfer cylinder 06 cooperating plate cylinder 07 together from these plate cylinders 07 arranged movably away and further preferably stored in a common subframe.

The at least one clamping device 21 has at least one front actuator 24 on, by means of a relative movement of the at least one front pressing element 23 relative to the at least one radially outer front clamping element 22 and thereby preferably at the same time relative to the cylindrical bale 12 of the plate cylinder 07 is feasible. This is preferably at least one front pressing element 23 by means of the at least one front actuating element 24 deformable. This is preferably at least one front pressing element 23 by means of the at least one front actuating element 24 shortened with respect to a substantially radial direction. Preferably, the at least one front pressing element extends 23 over at least 75% and more preferably at least 90% of an axial length of the cylinder bale 12 ,

Preferably, the at least one front clamping device 21 at least two front pressing elements 23 and / or at least one radially inner front clamping element 26 on. The at least two front pressing elements 23 are again preferred in each case as at least one leaf spring 23 and more preferably each as at least one spring package 23 formed, each of a plurality of, in particular flat abutting leaf springs 23 consist. The at least one radially inner front clamping element 26 is preferred as at least one radially inner front terminal strip 26 formed, which extends in the axial direction A, preferably over at least 75% and more preferably at least 90% of the axial length of the at least a channel 13 , The at least one radially inner front clamping element 26 is preferably arranged movably in and / or against a front clamping direction B, in particular on the at least one radially outer front clamping element 22 to and / or from the at least one radially outer front clamping element 22 path. The front clamping direction B preferably has essentially in the radial direction. This means that the front clamping direction B preferably has at least one component in the radial direction which is larger than an optionally present component in the circumferential direction D. The front clamping direction B is preferably aligned orthogonal to the axial direction A. The at least one radially inner front clamping element 26 is preferably arranged immovably with respect to the axial direction A. The at least one front contact pressure element 23 and preferably the at least two front pressing elements 23 is or preferably with the at least one radially inner front clamping element 26 in contact. Radial directions B; C, the axial direction A and the circumferential direction D refer to the cylinder barrel 12 and / or the axis of rotation 11 of the plate cylinder 07 ,

This is preferably at least one radially inner front clamping element 26 by means of the at least one front pressing element 23 and more preferably by means of the at least two front pressing elements 23 in the front clamping direction B on the at least one radially outer front clamping element 22 to be acted upon and / or charged with a force. The at least one front control element 24 is preferably with the at least one front pressing element 23 in direct contact. It is preferred in the circumferential direction D with respect to the plate cylinder 07 the at least one front control element 24 between the at least two radially inner front pressing elements 23 arranged. The at least one front control element 24 is preferred as at least a front Klemmlöseantrieb 24 , more preferably as at least one can be acted upon and / or acted upon by a pressure medium front release body 24 and even more preferred than at least one front release tube 24 , in particular front Klemmlöseschlauch 24 formed, which is further preferably filled with a fluid and / or filled, for example with compressed air. If below from the front clamp release hose 24 the speech is, so it is also generally a acted upon by a pressure medium and / or acted on front release body 24 meant. Preferably, the compressed air is in an interior of the at least one front Klemmlöseschlauchs 24 with a pressure of up to 8 bar or more acted upon and / or charged. The at least one front control element 24 but also as at least one hydraulic cylinder 24 and / or at least one pneumatic cylinder 24 and / or at least one electric motor 24 be educated. The simplicity of construction in the case of a clamp release hose 24 is however advantageous.

Regardless of the design of the at least one front control element 24 causes activation of the at least one front actuating element 24 preferably a shortening of the at least one front pressing element 23 and preferably the at least two front pressing elements 23 in at least the front clamping direction B, more preferably at least by an extension of the at least one front actuating element 24 in a direction orthogonal to the axial direction A and orthogonal to the front clamping direction B. This happens, for example, in the form of a deflection of the at least one front pressing element 23 and preferably by means of mutually opposed deflections of the at least two front pressing elements 23 , This causes a movement of the at least one radially inner front clamping element 26 from the at least one radially outer front clamping element 22 away and thus opening a front clamping gap 27 , The front clamping gap 27 is preferred by the at least one radially outer front clamping element 22 on the one hand and the at least one radially inner front clamping element 26 on the other hand. 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 arched, since the at least two front pressers 23 constantly under a more or less great bias. This is preferably also independent of a state of the front Klemmlöseschlauchs 24 the case and in particular due to the fact that a space is dimensioned so that the at least two front pressing elements 23 never, especially not with completely empty front grommet hose 24 , enough space is available to be completely relaxed. The at least one front grommet hose 24 is preferably between the at least two front pressing elements 23 arranged and preferably also extends in the axial direction A. The at least two front pressing elements 23 are movable by means of at least two front connecting elements, in particular pivotable with each other and / or with the main body 37 the at least one front clamping device 21 and / or with the at least one front clamping element 26 connected. The at least one front grommet hose 24 is at least from a preferred axial direction A considered between the at least two front connecting elements arranged.

At least one of the at least two front pressing elements 23 and preferably both front pressing elements 23 are preferably movable, more preferably pivotally mounted on the body 37 the at least one front clamping device 21 fastened, more preferably by means of at least one of the at least two front connecting elements. The at least two front pressing elements 23 are preferably movable, more preferably pivotally mounted on the at least one radially inner front clamping element 26 fastened, more preferably by means of at least one of the at least two connecting elements. 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. At least one clip element is preferred by the at least one radially inner front clamping element 26 educated. At least one clip element is preferred by the main body 37 the at least one front clamping device 21 educated.

The formed curvature shorten the at least two front pressing elements 23 However, for example, with respect to a direction of a connecting element through the at least one front Klemmlöseschlauch 24 to another connecting element, in particular with respect to the front clamping direction B. In particular, a straight-line distance between two ends of one and the same front pressing element 23 shortened. As a result, the at least one radially inner front clamping element moves 26 relative to the main body 37 the at least one front clamping device 21 and in particular to this and the clamping is solved.

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.

In particular, a straight-line distance between two ends of one and the same rear pressing element 63 shortened. As a result, the at least one radially inner rear clamping element moves 66 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 which pass through oblong holes of the at least two rear pressing elements 63 protrude through and at its two ends in each case with the main body 71 the at least one rear clamping device 61 or with the at least one radially inner rear clamping element 66 are connected.

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 adjusting element 131 , in particular a 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 or relative to the cylinder barrel 12 store rigidly arranged component. 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 19 facing rear edge surface 132 of the at least one sled 102 out than in the retracted position.

Is that at least a rear spacer 131 by means of a bearing in a component of the cylinder bale 12 or relative to the cylinder barrel 12 mounted rigidly mounted component, so is the at least one rear spacer 131 in particular in at least one retracted position and in at least one and preferably a plurality of extended positions relative to the cylinder barrel 12 arranged. In the at least one extended position of the at least one rear spacer 131 the at least one rear spacer protrudes 131 then preferably further in one on the at least one carriage 102 pointing direction over the at least one sled 102 facing second channel wall 19 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 none acting opposite forces, 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 19 located. Accordingly, even the smallest distances between the behave at least one front Klammspalt 27 and the at least one rear cleft gap 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 laid pressure plate 73 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 acts 73 and / or the restoring force of the at least one return element 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 pressure plate 73 is first stretched by the at least one tensioning drive 104 is activated, for example by the acted upon by a pressure medium and / or acted actuator 104 , in particular 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 plate 73 curious; excited. The at least one sled 102 preferably moves so far that a desired tension of the printing plate 73 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. Alternatively, the touched at least one slide 102 the at least one in the cylinder barrel 12 stored spacers 131 to the at least one sled 102 to stop.

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 plate 73 the at least one sled 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 131 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 is thus a maximum on the tensioned pressure plate 73 applied clamping force. 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 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 movably 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 rear clamping device 61 in turn preferably rests on one of the first carriage 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 rear 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. On both sides of the sledge-loosening 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 lowering of the pressure in the Inside of the sled-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 pressure plate 73 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 plate 73 curious; excited. The at least one sled 102 preferably moves so far until a balance between by the at least one tensioning drive 104 applied force and this counteracting forces sets. This is the case, for example, if a certain pressure inside the tension hose 104 prevails. Then it is preferred that at least one rear stop actuator 112 so far on the at least one sled 102 to move until the at least one rear stop actuator 112 the at least one stop body 111 at a stop contact 123 touched. The at least one rear stop actuator 112 is then 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 61 supported, more preferably against the rear body 71 , Actuations of the at least one tensioning drive 104 , the at least one sled 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 is thus a maximum on the tensioned pressure plate 73 applied clamping force. 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. The at least one stop drive and / or the at least one rear stop actuator 112 further preferably has at least one sensor which detects a position of the at least one stop drive, for example a rotational angle position of the at least one electric motor and / or the one position of the at least one rear stop element 112 detected.

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 movable 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 is the at least one stop body 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 plate 73 on the plate cylinder 07 and thus allows a particularly effective introduction of the printing plate 73 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.

Subsequently, in a third section of the tensioning process, 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 minimally further than intended for a printing operation. The printing plate is preferred 73 stretched with a second force. Preferably, the second force is the same size as the first force. The preferred fast clamping over the measure provided in printing operation ensures that a clamping force extends along the entire circumference of the printing plate 73 on the printing plate 73 can affect and not due to static friction only an edge area influenced by the clamping force, in particular, is stretched.

For this purpose, the at least one tensioning 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 plate 73 is now curious and the plate cylinder 07 is in an eighth mode in a first 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.

The seventh process operation, which is also called clamping process, in contrast, in connection with the fixing device 109 in the second embodiment, preferably as described below. First, in a first portion of the tensioning process, the pressure plate is preferred 73 prepared by the at least one sled 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 selected to be higher than that provided in the rear insertion process, because against which in the pressure plate 73 Constant voltage must be worked.

Following in a second section of the clamping process, the pressure plate 73 Relieved by the at least one 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.

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.

Following is the fixing device 109 clamped, for example by the pressure in Slide release hose 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 plate 73 is now curious and the plate cylinder 07 is in an eighth mode in a second embodiment.

Regardless of the embodiment of the clamping operation is preferred in the first portion of the clamping operation, the at least one carriage 102 by means of a first force on the at least one front clamping device 21 and the first channel wall 18 to move while keeping the pressure plate 73 tensioned, which is preferably the same size as a second force, with the at least one carriage in the third section of the tensioning process 102 on the at least one front clamping device 21 and the first channel wall 18 to move while keeping the pressure plate 73 is tense.

Such a convex deformation at the front end 74 the printing plate 73 can be at least partially through the entire printing plate 73 propagate in the circumferential direction D. The convex deformation at the front end 74 the printing plate 73 is preferably set to cause a concave deformation of the printed image on the printing plate 73 counteracts. It may be necessary, even at the rear end 76 the printing plate 73 take appropriate action, for example, at least one rear adjustment 131 adjusted accordingly.

For example, the at least two front contact body 39 ; 41 , in particular setscrews 39 ; 41 at their setting relative to the bulge of the at least one front 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 contact body 39 ; 41 , in particular setscrews 39 ; 41 for example, no straight line and / or a line other than previously curved together with the convexity preferably arranged with respect to the axial direction A therebetween. By acting forces, for example because of as a spring 107 trained support body 107 and / or the tensioned pressure plate 73 , then at least the at least one front clamping device 21 so preferably elastically deformed that axially outer portions of the at least one front clamping device 21 and the clamped pressure plate 73 less strong to the first channel wall 18 moved and / or pulled, for example, as an axially central region of the at least one front clamping device 21 and the clamped pressure plate 73 , The clamped pressure plate 73 So it's at the front end 74 concave deformed. Such a concave deformation at the front end 74 the printing plate 73 can be at least partially through the entire printing plate 73 propagate in the circumferential direction D. The concave deformation at the front end 74 the printing plate 73 is preferably set to give a convex deformation of the printed image on the printing plate 73 counteracts. Again, it may be necessary, even at the far end 76 the printing plate 73 take appropriate action, for example, at least one rear adjustment 131 adjusted accordingly.

For example, the at least two front contact body 39 ; 41 , in particular setscrews 39 ; 41 at their setting relative to the bulge of the at least one front clamping device 21 moved in opposite directions, so form the first channel wall 18 facing ends of the at least two front contact body 39 ; 41 , in particular setscrews 39 ; 41 together with the bulge preferably arranged with respect to the axial direction A therebetween, preferably furthermore a straight line or a line curved in the same way as previously, but which is relative to the front clamping gap 27 and / or the first channel wall 18 is aligned obliquely. By acting forces, for example because of as a spring 107 trained support body 107 and / or the tensioned pressure plate 73 , then becomes the at least one front clamping device 21 preferably together with the clamped pressure plate 73 such to the first channel wall 18 pressed that at least one front clamping device 21 preferably together with the clamped pressure plate 73 relative to the first 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 pressure plate 73 continue to the first canal wall 18 as a second axially outer region of the at least one front clamping device 21 and the clamped pressure plate 73 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 clamped pressure plate 73 So it's at the front end 74 obliquely on the plate cylinder 07 hung up. Such an oblique position of the printing plate 73 preferably grows through the entire pressure plate 73 in the circumferential direction D and is further preferably adjusted so that they a skew of the printed image on the printing plate 73 counteracts.

If necessary, that is, in particular with a correspondingly deformed printed image on the printing plate 73 , the at least two are front screws 39 ; 41 adjusted so that in superposition of the effects described above, a mixture of a skew of the printing plate 73 on the plate cylinder 07 on the one hand and a convex and / or concave deformation of the pressure plate 73 on the other hand results.

An inclination of the pressure plate 73 by means of the at least one front clamping device 21 possibly also requires a compensating inclination and / or a movement in the axial direction A of the at least one, by the at least one rear clamping device 61 with the pressure plate 73 connected carriage 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, is preferably between 1 mm and 10 mm, more preferably between 3 mm and 6 mm.

A partial process of the adjustment process to correct the plate tension and thus the length of the pressure plate 73 in the direction of contact on the one hand and the correction of convex and / or concave deformations of the rear end 76 the printing form 73 On the other hand, depending on the embodiment, the fixing device 109 preferably carried out analogously to the respective seventh process operation. However, on the one hand, preference is given to the first clamping and subsequent relieving of the pressure plate 73 waived 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 adjusted according to the desired new plate tension. Should the settings of the at least one rear stop actuator 112 or the at least one rear spacer 131 already assumed the ideal value in the trial process in the eighth process, it is preferred as described above, the seventh process operation for tensioning the printing plate 73 again, but using the previously used settings of the at least one rear stop actuator 112 or the at least one rear spacer 131 , An advantage of re-tensioning the printing plate 73 is, for example, that reproducible conditions prevail and the plate tension uniformly over the entire extent of the pressure plate 73 can be adjusted. That's why the printing plate becomes 73 at any setting the at least two front 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.

Having the tab for all inks and / or printing plates 73 measured and compared with a desired pressure image are preferably determined in an inspection process and an evaluation process necessary corrections of the printed image and in corrections of the settings of the at least one rear clamping device 61 transformed. Should be one of a certain pressure plate 73 If the resulting partial image is too short, then it is preferred to change the setting of the at least one rear spacer 131 determined and preferably calculated that a greater elongation of the corresponding pressure plate 73 cause. Should be one of a certain pressure plate 73 If the original partial image is too long, then it is preferred to change the setting of the at least one rear spacer 131 determined and preferably calculated that a weaker strain of the corresponding pressure plate 73 cause. In one embodiment, these corrections are made at different axially spaced rear spacers 131 a same plate cylinder 07 independently of one another and in particular with each other differently, more preferably on the basis of different correction values which are determined for different axial positions.

All are preferably on a second side of the printing substrate 09 arranged register pattern 151 built up the same among themselves, for example, six-color. Due to the dimensions of the register pattern 151 It is possible, especially narrow areas at the beginning and at the end of a particular substrate 09 with the register patterns 151 to provide and thereby keep a lot of waste paper low. A thickness of the lines of the reference elements 152 is preferably at most 0.5 mm.

In the inspection process, actual layers are preferred to desired positions of all reference elements 152 , in particular register marks 152 the at least one register pattern 151 preferably relative to the base reference element 153 , in particular the basic registration mark 153 the respective at least one register pattern 151 and / or preferably detected by means of the at least one register sensor. At least two register patterns are preferred in the inspection process 151 detected, each at least one of a same pressure plate 73 originating reference element 152 . in particular at least one of a same pressure plate 73 originating register mark 152 exhibit. For the sake of simplicity, register patterns are preferred 151 on the same side of the substrate 09 are arranged and each having a plurality of printing inks, detected sequentially, while register pattern 151 on different sides of the substrate 09 are arranged to be detected simultaneously to increase register accuracy.

In the case of at least one occurring in the circumferential direction D, exceeding a tolerance range deviation of an actual position relative to a desired position in the evaluation process are preferred and in particular taking into account further detected register pattern 151 new settings for at least one setting element 39 ; 41 ; 131 ; 144 at least one tensioning device 101 determined and preferably calculated, in which the at least one pressure plate 73 for example, is erroneously stretched or was, the at least one deviating in the circumferential direction D register mark 151 has caused. In the evaluation process, further preference is given to new settings for at least one adjustment element in each case 39 ; 41 ; 131 ; 144 at least two, even more preferably all clamping devices 101 determined and preferably calculated, in each of which at least one pressure plate 73 for example, is erroneously tense or was. Further preferred in the evaluation process are the new settings for a plurality of adjustment elements 39 ; 41 ; 131 ; 144 one or more fixtures 101 at the same time and / or taking into account mutual influences of the multiple adjustment elements 39 ; 41 ; 131 ; 144 determined and preferably calculated.

This in turn preferably takes place taking into account further registered register patterns 151 , A change in the temperature of a cylinder bale 12 conditionally preferably also a change in the temperature of the pressure plate arranged thereon 73 and vice versa.

An absolute position of different, on the same side of the substrate 09 arranged register pattern 151 each other is not necessarily relevant, as long as a relative position of reference elements 152 within each register pattern 151 given to each other with sufficient accuracy. An absolute position on different sides of the substrate 09 arranged, directly opposite each other register pattern 151 is very relevant especially in securities printing. Therefore, in each case a reference element is preferred in the evaluation process 152 a first, on the first page of the substrate 09 arranged register pattern 151 as the first base reference element 153 established. After that, a reference element is preferred 152 one of the first register pattern 151 opposite on the second side of the substrate 09 arranged second register pattern 151 as second base reference element 153 established. Preferences for plate cylinder are then preferred 07 determined and preferably calculated, by means of which the other reference elements 152 of the first register pattern 151 to the first base reference element 153 be aligned. Preferences for plate cylinder are then preferred 07 determined and preferably calculated, by means of which the other reference elements 152 of the second register pattern 151 to the second base reference element 153 be aligned.

An operator can preferably influence the method, for example by confirming or modifying new settings proposed by the machine control after the evaluation process, or by restarting the inspection process and / or the evaluation process, in particular with the manual selection of another reference element 152 as a basic reference element 153 , This can be advantageous if, for example, only the previous base reference element 153 from the other reference elements 152 deviates strongly.

In a first fitting process, at least one, for example, incorrectly tensioned printing plate is preferred 73 at least partially and more preferably completely relaxed at least with respect to the circumferential direction D and remains in the at least one front clamping device 21 and the at least one rear clamping device 61 clamped and is in accordance with the newly determined and preferably recalculated settings for the at least one adjustment 39 ; 41 ; 131 ; 144 , in particular the at least one front adjusting element 39 ; 41 and / or the at least one rear adjusting element 131 changed in the circumferential direction D on the respective plate cylinder 07 curious; excited. Under an at least partial relaxation of the printing plate 73 is understood that a on this pressure plate 73 is preferably reduced by at least 50%, more preferably at least 75%, and even more preferably at least 90%. For this purpose, preference is given to a pressure in which preferably as at least one actuatable with a pressure medium and / or acted actuator body 104 trained tensioning drive 104 preferably at least 50%, more preferably at least 75% and even more preferably at least 90% reduced. Under a complete relaxation of the printing plate 73 is understood that the on this pressure plate 73 acting clamping force by 100%, that is reduced to zero, so that in the connection no pressure plate 73 in the appropriate direction, here the circumferential direction D exciting force occurs more.

Further preferred are in the first fitting process at least two and even more preferably all, for example, incorrectly tensioned printing plates 73 at least partially and more preferably completely relaxed, at least with respect to the respective circumferential direction D, and preferably remain in the respective at least one front clamping device 21 and the respective at least one rear clamping device 61 the respective at least one clamping device 101 clamped and are subsequently preferably by means of the respective at least one clamping device 101 in accordance with the newly determined and preferably newly calculated settings for the respective at least one setting element 39 ; 41 ; 131 ; 144 changed in the circumferential direction D on the respective plate cylinder 07 curious; excited. Preferably, the first fitting process of at least two, for example erroneously tensioned printing plates 73 at least temporarily at the same time. In the first fitting process, a tension within the at least one pressure plate preferably remains 73 with respect to the axial direction A unchanged. The setting of the at least one adjusting element is preferred 39 ; 41 ; 131 ; 144 and more preferably all newly adjusted adjustment elements 39 ; 41 ; 131 ; 144 machine-controlled and by means of at least one corresponding drive 43 ; 44 ; 134 ; 141 performed. The at least one printing plate is preferred 73 after re-tensioning the at least one pressure plate 73 at least minimally relieved, to at least two rear adjustment elements 131 both with at least one the at least one rear clamping device 61 carrying sled 102 as well as with the second channel wall 19 stay in contact.

In the fitting process or preferably in a second fitting process, the at least one temperature of the at least one pressure plate is preferred 73 and / or the at least one cylinder bale 12 and / or the temperature control, in particular tempering changed according to the new settings. In particular, therefore, new settings for a temperature of a temperature control medium designed as a tempering fluid are preferably determined and preferably calculated in the evaluation process, the temperature being that of the plate cylinder 07 flows through, on which the at least one, for example, in their axial Expansion faulty pressure plate 73 is tense and is changed in the second adjustment process, the temperature of this tempering fluid formed as tempering according to the new settings. Preferably, the temperature of the temperature control, in particular tempering is measured and controlled. For example, it can be empirically or computationally recorded beforehand which temperature changes are necessary in order to achieve desired length changes in the print image. The tempering fluid is preferably controlled with an accuracy of 0.3 ° C or better. The temperature of the tempering fluid is preferably changed within a temperature range of at most 20 ° C. The temperature control means may for example also have an alternative or additional heating, which is designed, for example, as at least one electrical heating resistor and / or at least one radiant heater.

A temperature difference between two different printing plates is preferred 73 on different plate cylinders 07 are arranged, after the fitting process larger or smaller than before the fitting process. This includes in particular those cases in which there is no temperature difference before the fitting process, but then there is a temperature difference and those cases in which before the fitting a temperature difference is present, but then no longer and such cases in which before the fitting process and After the adjustment process temperature differences are present, but different. In the optionally second adaptation process, the temperatures of two and preferably all of the printing plates which are defective, for example, in their axial extent, are preferred 73 and / or respective cylindrical bales 12 the respective plate cylinder 07 and / or tempering changed according to the new settings. In the optionally second adaptation process, a stress within the at least one pressure plate is preferred 73 maintained unchanged with respect to a circumferential direction D. As an angular position of pixels, especially at a temperature-induced change in length of the printing plate 73 is not dependent on the temperature, but due to expansion at most a radial position of the pixels is changed, it is not necessary to make adjustments after the temperature change, which affect the angular position and / or circumferential direction D. The angular position is alone by the corresponding drive of the plate cylinder 07 established. Radial changes in the position of the printing plate 73 have at most such effects that a minimally changed rolling behavior of the printing plate 73 on the transfer cylinder 06 is produced. However, the affected a print quality preferably at least not noticeable.

Preferred is a number of registered register patterns evaluated with mutual consideration 151 at least as large as a sum of front contact bodies 39 ; 41 and / or rear spacers 131 trained adjustment elements 39 ; 41 ; 131 one of the at least two plate cylinders 07 , Preferred is a number of registered register patterns evaluated with mutual consideration 151 at least eight per printing plate 73 , more preferably fourteen per printing plate 73 , A preferred arrangement of register patterns 151 provides that with respect to the axial direction A at least one register pattern 151 has a same axial position, as at least one adjusting element 39 ; 41 ; 131 , Another arrangement of register patterns 151 provides that at least one adjustment 39 ; 41 ; 131 in its position with respect to the axial direction A not with a register pattern 151 matches. In this case, corresponding conversions are necessary. This is especially the case when a particularly narrow substrate 09 is used, which is narrower than a maximum distance between two adjustment elements 39 ; 41 ; 131 in the axial direction A.

The evaluation process may also overlap with the fitting process, for example, such that only the at least one printing plate 73 For example, partially or completely relaxed and then that the evaluation process takes place and that then the at least one printing plate 73 is stretched again.

In the case of a new setting of at least one temperature, for example a tempering agent, in particular tempering fluid, a particularly rapid adaptation is preferably achieved by means of overriding the temperature control. The tempering fluid is preferably at least partially within the at least one bore 126 arranged and more preferably able to flow through them. Preferably, the plate cylinder 07 the at least one hole 126 on, in which a tempering fluid, for example water with a rust inhibitor, arranged and / or can be arranged and / or which can be flowed through and / or flowed through by a tempering fluid. More preferably, the plate cylinder 07 several holes 126 further preferably each over at least 90% of the axial length of the cylinder bale 12 of the plate cylinder 07 extend. This will be a contact surface of the cylinder bale 12 enlarged with the tempering fluid. Further preferred is in at least one bore 126 at least one flow body 136 ; 137 and / or balancing body 136 ; 137 arranged. A flow body 136 ; 137 serves to a relatively large cross section of the at least one bore 126 thereby reducing, on the one hand, a flow velocity of the tempering fluid in the at least one bore 126 on the other hand for a turbulent flow and thus a better heat transfer between cylindrical bales 12 and to create tempering fluid. This will cause the cylinder barrel 12 and thus also the pressure plate arranged thereon 73 more effective tempered. A compensation body 136 ; 137 serves to unbalance the plate cylinder 07 compensate. At least one first flow body is preferred 136 ; 137 formed tubular, so that it flows outside passing therethrough tempering thereof is unaffected, whether still a second compensating body 137 inside the first compensation body 136 is arranged to compensate for imbalances or not.

Preferably, the fitting process is performed on a plurality of plate cylinders 07 the printing press 01 and more preferably on all plate cylinders 07 the printing press 01 at least temporarily at the same time.

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 plate 73 even with such settings of the circumferential register and / or the page register remains unchanged on the plate cylinder 07 clamped.

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.

In particular, an adjustment of all adjustment elements preferably takes place 39 ; 41 ; 131 ; 144 , in particular as a front contact body 39 ; 41 trained front adjustment elements 39 ; 41 and the as a rear spacer 131 trained rear adjustment elements 131 motor-driven and / or machine-controlled, more preferably regulated by the machine control.

Precision of the printing result can be further increased if for each plate cylinder 07 a profile is created, the deviations of the shape of this plate cylinder 07 represents an ideal cylindrical shape and then when imaging and / or exposing the printing plates 73 each respective profile is considered.
