A printing machine 01 designed as a rotary printing machine 01, for example as a sheet-fed rotary printing press 01, is described by way of example below. The printing machine 01 is, for example, a printing machine 01 used in the printing of value. The printing machine 01 is designed as a printing machine 01 which prints a preferably sheet-shaped printing material 09, ie as a sheet-fed printing machine 01. The printing machine 01 has at least one printing unit 02 with at least one printing unit 08 and at least one inking unit on, wherein the at least one printing unit 08 has at least one forme cylinder 07. The at least one forme cylinder 07 is preferably designed as at least one plate cylinder 07. Preferably, a plurality of printing units 08 and a plurality of inking units are provided in the at least one printing unit 02 in order to print different printing inks on the same printing substrate 09 in a same production, for example according to the number of these inking units. In one embodiment, printing units 08 are arranged in the same printing unit 02, the preferably work according to different pressure principles. For example, at least one printing unit 08 is designed as a flat printing unit 08, for example an offset printing unit 08, and / or at least one other printing unit 08 is designed as a high-pressure unit 08, in particular an indirect high-pressure unit 08. These different printing units 08 then print, for example, in a same production a same printing substrate 09, more preferably by means of at least one common transfer cylinder 06. In one embodiment, at least one printing unit is designed as a steel engraving printing unit 08.

The printing machine 02 preferably has at least one printing material source 03 in the form of a sheet feeder 03. The printing press 01 preferably has at least one sheet deposit 04, which preferably has at least one and more preferably at least three discard piles. Preferably, at least one dryer along a transport path of the printing material 09 is arranged in front of the at least one storage stack, for example an infrared radiation dryer and / or an ultraviolet radiation dryer. For example, the printing machine has ten forme cylinders 07, in particular plate cylinders 07. A sheet-fed rotary printing machine 01 with a printing unit 02 with a plurality of printing units 08 is also exemplary in FIG Fig. 1 shown. For example, the printing machine 01 has at least one printing unit 08 and at least one dryer, each of which is arranged on the printing material 09 acting along a transport path of the printing material 09 before transfer cylinders 06 described below.

Preferably, the at least one printing unit 02 has at least one pair of transfer cylinders 06 formed as blanket cylinders 06, through the common contact area of which a printing gap 16 is defined. Preferably, each of the at least two transfer cylinders 06 is in rolling contact with at least one plate cylinder 07 and more preferably several, for example four plate cylinders 07. Preferably, the printing unit 02 is designed as a multi-color printing unit 02. Each This plate cylinder 07 is preferably associated with at least one inking unit. At least one printing plate 73 in the form of at least one and preferably exactly one printing plate 73 is preferably arranged on the at least one plate cylinder 07. Preferably, exactly one pressure plate 73 is arranged or provided on each plate cylinder 07, whose extension in an axial direction A of the plate cylinder 07 preferably corresponds to at least 75% and more preferably at least 90% of an extension of a cylinder bale 12 of the at least one plate cylinder 07 in this axial direction A. , Preferably, the at least one transfer cylinder 06 has a circumference which corresponds to an integer multiple of the circumference of the at least one plate cylinder 07, for example three times.

Preferably, each inking unit cooperating with a plate cylinder 07 is movably arranged away from this respective plate cylinder 07. As a result, the corresponding plate cylinder 07 is accessible for maintenance and in particular for a printing plate change. More preferably, the inking units of all cooperating with a common transfer cylinder 06 plate cylinder 07 are arranged together movable away from these plate cylinders 07 and further preferably stored in a common subframe. For example, with a corresponding arrangement of the at least one plate cylinder 07 and the associated inking unit, at least one printing plate store is moved up to the at least one plate cylinder 07. This at least one printing plate store contains at least one printing plate 73 to be placed on the at least one plate cylinder 07. The at least one printing plate store preferably contains a plurality of printing plates 73, which are assigned to a plurality of plate cylinders 07 and / or. The at least one pressure plate storage is used in addition to a controlled positioning of the pressure plate 73 relative to the corresponding plate cylinder 07 and a protection of the aufzulegenden pressure plate 73. Preferably, at least one spinning means, for example arranged a spinning roller, and / or serves to when placing the pressure plate 73rd on the plate cylinder 07 this pressure plate 73 to the plate cylinder 07 to press.

The pressure plate 73 preferably has a dimensionally stable carrier plate and at least one plate coating. The dimensionally stable carrier plate consists for example of a metal or an alloy, for example aluminum or steel. In at least one dry offset printing unit or waterless offset printing unit, at least one support plate made of steel is preferably used. In at least one wet offset printing unit, at least one aluminum support plate is preferably used. The carrier plate preferably has a thickness, that is to say a smallest dimension of 0.25 mm to 0.3 mm. The at least one plate coating defines a printed image of the printing plate 73. The printed image can be determined, for example, by virtue of parts of a surface of the printing plate 73 having hydrophobic properties, while other parts of the surface of the printing plate 73 have hydrophilic properties. Depending on the characteristics of an ink used, only selected areas of the printing plate 73 then transfer this printing ink. Such a printing plate 73 transfers color after a planographic printing process, in particular offset printing process. In this case, a waterless offset printing method can be used or a so-called wet offset printing method can be used, for which the printing unit then has at least one dampening unit.

Alternatively, the printed image is determined by the fact that the plate coating is first applied over the entire surface and is selectively cured in an exposure process, while the uncured areas are washed out, for example with water. Alternatively, a coating is selectively applied or selectively removed by other means, such as by etching or mechanically engraving. This results in areas, for example, not washed out areas, which are arranged elevated relative to the support plate and areas, such as washed out areas, which are lower and are formed for example by the exposed support plate. Such a printing plate 73 transfers ink by a high-pressure process, preferably on the corresponding transfer cylinder 06, from where from it is transferred to the substrate 09. Since the print image is only transferred from the transfer cylinder 06 to the printing material 09, this is an indirect high-pressure process.

The pressure plate 73 is alternatively formed as a stencil printing plate 73. Such a stencil printing plate 73 has, for example, relatively coarse raised areas which are completely colored and from which ink is transferred to a steel piercing cylinder. Such a steel engraving cylinder has fine engraving, in which the ink is stored while it is removed outside the engraving, for example, wiped off. Preferably, different printing inks are collected by a plurality of printing plates 73 on the steel engraving cylinder, wherein more preferably the regions of different colors on the steel engraving cylinder overlap at most minimally. By rolling contact and for example by pressing the ink is transferred from the engravings on a substrate. The printing plate 73 is alternatively designed as a flexographic printing plate 73 for direct or indirect flexographic printing. Regardless of the design of the printing plate 73, the printing plate 73 is used for a transfer of printing ink and / or paint. Accordingly, in the foregoing and hereinafter always when it comes to ink is meant, alternatively, a paint, in particular in the case of the flexographic printing plate 73rd

Regardless of the material used, the pressure plate 73 preferably has a front end 74 and a rear end 76. The front end 74 of the pressure plate 73 is preferably an advancing in a printing operation end 74 of the pressure plate 73. The rear end 76 of the pressure plate 73 is preferably a trailing in the printing operation end 76 of the pressure plate 73. The front end 74 of the pressure plate 73 preferably has a front contact portion 74, which serves to clamp the pressure plate 73 on the plate cylinder 07. This contact region preferably has no ink-transferring plate coating. The rear end 76 of the pressure plate 73 preferably has a rear contact region 76, which is a clamping of the pressure plate 73 on the plate cylinder 07 is used. This contact region preferably has no ink-transferring plate coating. Preferably, the pressure plate 73 in the contact areas exclusively from the dimensionally stable support plate. The contact areas ensure high reproducibility and high reliability of at least one clamping contact of the pressure plate 73 with components of the plate cylinder 07. The front end 74 and / or the rear end 76 of the pressure plate 73 is or are preferably as bent from a central portion of the pressure plate 73 deviating clamping portions 74; 76 trained. The clamping regions 74; 76 are preferably each angled between 15 ° and 40 ° with respect to the middle part of the pressure plate 73, more preferably between 17 ° and 22 ° at the front end 74 and between 35 ° and 40 ° at the rear end 76. Preferably, the front end 74 and the rear end 76 of the pressure plate 73 each have an extent in the circumferential direction D that is between 10 mm and 30 mm, more preferably at least 15 mm, and even more preferably between 15 mm and 20 mm. An application of the printing plate 73 on the plate cylinder 07 is preferably carried out at least partially by means of a laying device, for example an automatic plate feeder.

In a printing operation of the printing press 01, at least one sheet 09 tapped by a sheet feeder 03, preferably a sequence of several sheets 09, is fed to the printing unit 02. The printing unit 02 operates preferably in perfecting, wherein both sides of the printing material 09 are inked in the printing gap 16 at the same time. More preferably 16 multicolor printed images are transferred to the printing substrate 09 in a single printing step in the printing nip. These multicolor print images are preferably composed of individual color partial color images, which were previously transferred from a plurality of plate cylinders 07 to the corresponding transfer cylinder 06 and collected there. The printing unit 02 preferably consists of two halves of essentially the same construction. Each of the halves has a preferably designed as a blanket cylinder 06 transfer cylinder 06. The plate cylinder 07 and in particular on it arranged printing plates 73 are preferably inked by one inking unit, each with a different ink. The plate cylinders 07 preferably each transmit at least one printed image to the corresponding transfer cylinder 06, to which they are employed. As a result, a multicolored print image is preferably created on each transfer cylinder 06, which is further preferably transferred to the printing material 09 in a single step.

As described, for example, each transfer cylinder 06 is associated with a plurality of, preferably four, plate cylinders 07, wherein an inking unit is set or at least adjustable to each of these plate cylinders 07, so that preferably the two transfer cylinders 06 can jointly print, for example, up to eight printing inks. Preferably, at least one common counter-pressure cylinder 06 and the plate cylinder 07 engaged therewith and / or cooperating therewith are coupled to each other and to at least one common drive motor via at least one gear transmission. The inking units may be coupled thereto or coupled, but preferably each have their own drive motors.

The at least one plate cylinder 07 of the printing machine 01 will be explained in more detail below. At least the plate cylinders 07 cooperating with the transfer cylinders 06 are preferably designed substantially identical in construction. Each plate cylinder preferably has the cylindrical bale 12 and two cylindrical pins 17.

The at least one front pressing element 23 is preferably designed as at least one front leaf spring 23, more preferably as at least one front spring packet 23, which consists of several, in particular flat abutting leaf springs 23. The at least one clamping device 21 has at least one front adjusting element 24 by means of which 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 effected. Preferably, the at least one front pressing element 23 is deformable by means of the at least one front adjusting element 24 in itself. Preferably, the at least one front pressing element 23 can be shortened by means of the at least one front adjusting element 24 with respect to a substantially radial direction. Preferably, the at least one front pressing element 23 extends over at least 75% and more preferably at least 90% of an axial length of the cylinder bale 12.

The at least one front clamping device 21 preferably has at least two front pressing elements 23 and / or at least one radially inner front clamping element 26. The at least two front pressing elements 23 are in turn preferably each formed as at least one leaf spring 23 and more preferably each as at least one spring assembly 23, each consisting of several, in particular flat abutting leaf springs 23. The at least one radially inner front clamping element 26 is preferably designed as at least one radially inner front clamping strip 26 extending in the axial direction A, preferably over at least 75% and more preferably at least 90% of the axial length of the at least one channel 13 a radially inner front clamping element 26 is preferably movably arranged in and / or counter to a front clamping direction B, in particular to the at least one radially outer front clamping element 22 and / or of the at least a radially outer front clamping element 22 away. 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 immovably arranged with respect to the axial direction A. The at least one front pressing element 23 and preferably the at least two front pressing elements 23 are or are preferably in contact with the at least one radially inner front clamping element 26. Radial directions B; C, the axial direction A and the circumferential direction D refer to the cylindrical bale 12 and / or the axis of rotation 11 of the plate cylinder 07th

Preferably, the at least one radially inner front clamping element 26 by means of the at least one front pressing element 23 and further preferably by means of the at least two front pressing elements 23 in the front clamping direction B to the at least one radially outer front clamping element 22 to be acted upon and / or acted upon , The at least one front adjusting element 24 is preferably in direct contact with the at least one front pressing element 23. Preferably, in the circumferential direction D with respect to the plate cylinder 07, the at least one front adjusting element 24 is arranged between the at least two radially inner front pressing elements 23. The at least one front actuating element 24 is preferably designed as at least one front clamping release drive 24, more preferably as at least one front dissolving body 24 which can be acted upon and / or acted upon by a pressure medium and even more preferably as at least one front dissolving hose 24, in particular front clamping dissolving hose 24, which is further preferably filled with a fluid and / or can be filled, for example with compressed air. If, in the following, the front clamping release hose 24 is mentioned, this also generally refers to a front release body 24 which can be acted upon and / or acted upon by a pressure medium. Preferably, the compressed air 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 acted upon. However, the at least one front adjusting element 24 can also be designed as at least one hydraulic cylinder 24 and / or at least one pneumatic cylinder 24 and / or at least one electric motor 24. However, the simplicity of construction in the case of a clamping release tube 24 is advantageous.

Irrespective of the design of the at least one front adjusting element 24, activation of the at least one front adjusting element 24 preferably causes a shortening of the at least one front pressing element 23 and preferably of 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 adjusting element 24 in a direction orthogonal to the axial direction A and orthogonal to the front clamping direction B. This takes place, for example, in the form of a deflection of the at least one front pressing element 23 and preferably by means of opposite deflections of the at least two front pressing elements 23 causes a movement of the at least one radially inner front clamping element 26 away from the at least one radially outer front clamping element 22 and thus opening a front clamping gap 27. The front clamping gap 27 is preferably dur 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 formed. The at least two front pressing elements 23 are preferably flexibly connected to the front base body 37, more preferably such that they can not be removed therefrom, but nevertheless are movable relative to it, in particular during its deformation. The at least two front pressing elements 23 are preferably flexibly connected to the at least one radially inner front clamping element 26, more preferably such that they can not be removed therefrom, but nevertheless are movable relative to it, in particular during its deformation. In particular, that is preferably the at least one radial inner front clamping element 26 so flexibly connected to the at least two front pressing elements 23, so that a shortening of the at least one front pressing element 23 inevitably causes a movement of the at least one radially inner front clamping element 26 against the front clamping direction B.

In a preferred embodiment, the at least two front pressing elements 23 are substantially, in particular apart from a deflection or curvature, arranged parallel to each other and extend in the axial direction A and substantially in a second orthogonal direction of extent, preferably at least one radial component having. Preferably, however, the second extension direction is slightly curved and each front pressing member 23 slightly curved, since the at least two front pressing elements 23 are constantly under a more or less large bias. This is preferably independent of a state of the front clamping release hose 24 of 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 Klemmlöseschlauch 24, enough space available to be completely relaxed. The at least one front clamping release hose 24 is preferably arranged between the at least two front pressing elements 23 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 of the at least one front clamping device 21 and / or connected to the at least one front clamping element 22. The at least one front clamping release hose 24 is arranged, viewed at least from a preferably axial direction A, between the at least two front connecting elements.

At least one of the at least two front pressing elements 23 and preferably both front pressing elements 23 are preferably movable, more preferably pivotable fixed to the base body 37 of the at least one front clamping device 21, 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 attached to the at least one radially inner front clamping element 26, more preferably by means of at least one of the at least two connecting elements. On both sides of the at least one front clamping release hose 24, at least one clamping element is arranged so as to prevent removal of ends of the at least two front pressing elements 23 from each other over a maximum distance. This causes, when the at least one front clamping release tube 24 is inflated, the at least two front pressing elements 23 do not merely pivot away from each other, but bulge outward from the at least one front clamping release tube 24, since their ends do not extend from the ends of the adjacent pressing elements 23 can remove. Preferably, at least one clip element is formed by the at least one radially inner front clamping element 26. Preferably, at least one clip element is formed by the base body 37 of the at least one front clamping device 21.

However, due to the formed curvature, the at least two front pressing elements 23 shorten, for example, with respect to a direction from one connecting element through the at least one front clamping release hose 24 to another connecting element, in particular with respect to the front clamping direction B. In particular, a rectilinear 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 26 moves relative to the base body 37 of the at least one front clamping device 21 and in particular to this and the clamping is released. For example, the at least two connecting elements are formed as connecting pins, which protrude through slots of the at least two front pressing elements 23 and at its two ends in each case with the Base body 37 of the at least one front clamping device 21 or with the at least one radially inner front clamping element 26 are connected.

When the at least one front actuating element 24 is deactivated, a restoring force of the at least one front pressing element 23 causes the at least one radially inner front clamping element 26 to move toward the at least one radially outer front clamping element 22 and thus to close the front clamping gap 27. Such deactivation the at least one front adjusting element 24 consists, for example, in a lowering of the pressure in the interior of the front clamping solution hose 24, for example, to an ambient pressure, in particular atmospheric pressure. Preferably, the at least one front pressing element 23 and more preferably are the at least two front pressing elements 23 at any time under an at least minimum bias, regardless of whether the at least one front clamping device 21 is open or closed and regardless of whether a pressure plate 73 in the front nip 27 is or not. In particular, the front leaf springs 23, more preferably the at least one front spring packet 23 are slightly bent and biased at all times.

The at least one radially inner front clamping element 26 is preferably always held by means of at least one front pressure element 28, for example at least one front pressure spring 28 with respect to the circumferential direction D in a defined position, for example pressed against a front alignment surface 29. The front alignment surface 29 is preferably arranged between the at least one front pressure element 28 and the first channel wall 18. The front alignment surface 29 is preferably a surface 29 of the at least one front base body 37. In particular, a force exerted by the at least one front pressure element 28 on the at least one radially inner front clamping element 22 acts in a direction toward the first channel wall 18. The force exerted by the at least one front pressure element 28 is preferably smaller than that of the at least one front one Pressing element 23 applied force in the clamped state. This ensures that the at least one radially inner front clamping element 26 is held in a defined position in the circumferential direction D, but is not impaired by movements of the at least one front pressure element 28 in the front clamping direction B. The position defined in the circumferential direction D ensures that the pressure plate 73 is not unintentionally moved during the clamping process. Thereby, a high precision of the position of the pressure plate 73 is maintained in its clamped state and in particular during the clamping operation.

The at least one radially inner front clamping element 26 and / or the at least one radially outer front clamping element 22 preferably has or have at least one surface of a hardened material, for example hardened steel, which preferably additionally or alternatively with a structure of regular and / or irregular Elevations and / or depressions is provided, for example, intersecting rectilinear notches.

The at least one rear adjusting element 64 is preferably designed as at least one rear clamping dissolving drive 64, more preferably as a rear dissolving body 64 which can be acted upon and / or acted upon by a pressure medium and even more preferably as at least one rear dissolving hose 64, in particular behind the rear clamping hose 64, which is also preferred a fluid filled and / or filled, for example, with compressed air. If, in the following, the rear clamping solution hose 64 is mentioned, this also generally means a rear release body 64 that can be acted upon and / or acted upon by a pressure medium. Preferably, the compressed air in an interior of at least one rear Klemmlöseschlauchs 64 with a pressure of up to 8 bar or more acted upon and / or acted upon. However, the at least one rear adjusting element 64 can also be designed as at least one hydraulic cylinder 64 and / or at least one pneumatic cylinder 64 and / or at least one electric motor 64. However, the simplicity of construction in the case of a clamping release hose 64 is advantageous.

Regardless of the configuration of the at least one rear control element 64, activation of the at least one rear control element 64 preferably effects a shortening of the at least one rear contact element 63 and preferably of the at least two rear contact elements 63 in at least the rear clamping direction C, more preferably at least by an extension of the at least one rear actuating element 64 in a direction orthogonal to the axial direction A and orthogonal to the rear clamping direction C. This takes place, for example, in the form of a deflection of the at least one rear pressing element 63 and preferably by means of opposite deflections of the at least two rear pressing elements 63 causes a movement of the at least one radially inner rear clamping element 66 away from the at least one radially outer rear clamping element 62 and thus opening a rear clamping gap 67. The rear Clamping gap 67 is preferably formed by the at least one radially outer rear clamping element 62 on the one hand and the at least one radially inner rear clamping element 66 on the other. The at least two rear pressing elements 63 are preferably flexibly connected to the rear base body 71, more preferably such that they can not be removed therefrom but are nevertheless movable relative to it, in particular during its deformation. The at least two rear pressing members 63 are preferably flexibly connected to the at least one radially inner rear clamping member 66, more preferably such that they can not be removed therefrom but are still movable relative thereto, in particular during their deformation. In particular, the at least one radially inner rear clamping element 66 is thus preferably flexibly connected to the at least two rear pressing elements 63 so that a shortening of the at least one rear pressing element 63 the at least one radially inner rear clamping element 66 necessarily causes a movement of the at least one radially inner rearward Clamping elements 66 against the rear clamping direction C causes.

In a preferred embodiment, the at least two rear pressing elements 63 are substantially, in particular apart from a deflection or curvature, arranged parallel to each other and extend in the axial direction A and substantially in a second orthogonal direction of extent, preferably at least one radial component having. Preferably, however, the second extension direction is slightly curved and each rear contact element 63 slightly curved, since the at least two rear contact elements 63 are constantly under a more or less large bias. This is preferably the case regardless of a state of the rear Klemmlöseschlauchs 64 and in particular due to the fact that a space is dimensioned so that the at least two rear contact elements 63 never, especially not with completely deflated rear Klemmlöseschlauch 64, enough space available to be completely relaxed. The at least one rear grommet hose 64 is between the at least two rear pressing elements 63 and preferably also extends in the axial direction A. The at least two rear pressing elements 63 are movable by means of at least two rear connecting elements, in particular pivotable with each other and / or with the main body 71 of the at least one rear clamping device 61 and / or with the at least one rear clamping element 62 connected. The at least one rear clamping release hose 64 is arranged, viewed at least from a preferably axial direction A, between the at least two rear connecting elements.

At least one of the at least two rear pressing elements 63 and preferably both rear pressing elements 63 are preferably movable, more preferably pivotally attached to the main body 71 of the at least one rear clamping device 61, more preferably by means of at least one of the at least two rear connecting elements. The at least two rear pressing elements 63 are preferably movable, more preferably pivotally attached to the at least one radially inner rear clamping element 66, more preferably by means of at least one of the at least two connecting elements. On both sides of the at least one rear clamping release hose 64, at least one clamping element is arranged so as to prevent removal of ends of the at least two rear pressing elements 63 from each other over a maximum distance. This causes inflation of the at least one rear gripper hose 64 to cause the at least two rear abutment members 63 to pivot away from each other rather than arch outwardly away from the at least one grommet hose 64, since their ends are not spaced from the ends of the adjacent press members 63 can remove. Preferably, at least one clip element is formed by the at least one radially inner rear clamping element 66. Preferably, at least one clip element is formed by the base body 71 of the at least one rear clamping device 61.

However, for example, with respect to a direction from one connecting element through the at least one rear clamping release hose 64 to another connecting element, in particular with respect to the rear clamping direction C, the at least two rear pressing elements 63 shorten due to the formed curvature. In particular, a rectilinear distance between two ends of the same rear one Pressing 63 shortened. As a result, the at least one radially inner rear clamping element 66 moves relative to the main body 71 of the at least one rear clamping device 61 and in particular to this and the clamping is released. For example, the at least two connecting elements are designed as connecting pins, which project through slots of the at least two rear pressing elements 63 and are connected at their two ends to the main body 71 of the at least one rear clamping device 61 or to the at least one radially inner rear clamping element 66.

Upon deactivation of the at least one rear actuating element 64, a restoring force of the at least one rear pressing element 63 causes a movement of the at least one radially inner rear clamping element 66 on the at least one radially outer rear clamping element 62 and thus closing the rear clamping gap 67. Such a deactivation the at least one rear actuating element 64 consists, for example, in a lowering of the pressure in the interior of the rear clamping hose 64, for example, to an ambient pressure, in particular atmospheric pressure. Preferably, this is at least one rear contact pressure 63 and more preferably the at least two rear contact elements 63 at any time under an at least minimum bias, regardless of whether the at least one rear clamping device 61 is open or closed and regardless of whether a pressure plate 73 in the rear nip 67 is or not. In particular, the rear leaf springs 63, more preferably the at least one rear spring package 63 are preferably slightly bent and biased at all times.

The at least one radially inner rear clamping element 66 is preferably always held by means of at least one rear pressure element 68, for example at least one rear pressure spring 68 with respect to the circumferential direction D in a defined position, for example pressed against a rear alignment surface 69. The rear alignment surface 69 is preferably arranged between the at least one rear pressure element 68 and the second channel wall 19. The rear alignment surface 69 is preferably a surface 69 of the at least one rear base body 71. In particular, a force exerted by the at least one rear pressure element 68 on the at least one radially inner rear clamping element 62 acts in one direction towards the second channel wall 19. The force exerted by the at least one rear pressure element 68 is preferably smaller than the force exerted by the at least one rear pressure element 63 in the clamped state. This ensures that the at least one radially inner rear clamping element 66 is held in the circumferential direction D in a defined position, but is not affected by the at least one rear pressure element 68 with respect to movements in the rear clamping direction C. The position defined in the circumferential direction D ensures that the pressure plate 73 is not unintentionally moved during the clamping process. Thereby, a high precision of the position of the pressure plate 73 is maintained in its clamped state and in particular during the clamping operation.

The at least one radially inner rear clamping element 66 and / or the at least one radially outer rear clamping element 62 preferably has or have at least one surface of a hardened material, for example hardened steel, which preferably additionally or alternatively has a structure of regular and / or irregular Elevations and / or depressions is provided, for example, intersecting rectilinear notches. This improves in the case of a clamped pressure plate 73 a frictional connection between the pressure plate 73 on the one hand and the at least one radially inner rear clamping element 66 and / or the at least one radially outer rear clamping element 62 on the other.

The at least one rear clamping device 61 is preferably part of at least one carriage 102 of the at least one tensioning device 101. The at least one carriage 102 and thus the at least one rear clamping device 61 is preferably arranged to be movable at least partially along a tensioning path and / or in a tensioning direction E. Preferably, the clamping path extends orthogonal to the axis of rotation 11 of the plate cylinder 07. Preferably, the clamping path extends within a plane whose surface normal is oriented parallel to the axis of rotation 11 of the plate cylinder 07. The tensioning path preferably extends substantially in and / or against the circumferential direction D or more preferably in and / or against a tensioning direction E which is preferably tangential to the circumferential direction D. Preferably, the at least one carriage 102 extends within the at least one channel 13 along the tensioning path the at least one front clamping device 21 arranged to be movable.

A distance traveled for clamping the clamping distance is preferably between 0.1 mm and 2 mm long, more preferably between 0.5 mm and 1.2 mm. The tensioning direction E is preferably aligned parallel to the second bottom surface 108 of the channel 13 in the region of the rear clamping device 61. The maximum adjustment path of the at least one carriage 102 is preferably at least as large relative to the cylindrical bale 12 of the plate cylinder 07 in and / or counter to the tensioning direction E as a dimension measured in the tensioning direction E of an intended or actual contact surface of one in the at least one rear clamping device 61 clamped pressure plate 73 with the at least one radially outer clamping element 62 of the at least one rear clamping device 61st The at least one rear clamping device 21 is preferably mounted by means of at least one anchoring, for example at least one, for example, along this second bottom surface 108 of the channel 13 preferably substantially in a direction orthogonal to the axis of rotation 11 of the plate cylinder 07 extending rail. As a result, the entire rear clamping device 61 is preferably at least linearly movable relative to the cylindrical bale 12. This serves on the one hand a simplified introduction of the rear end 76 of the pressure plate 73 in the at least one rear clamping device 61 and on the other hand a voltage and / or orientation of both in the at least one front clamping device 21 and the at least one rear clamping device 61 clamped pressure plate 73rd

At least one drive 104 embodied as a tensioning drive 104 is arranged in connection with the at least one second clamping device 61. By means of the at least one tensioning drive 104, at least one preferably adjustable force can be exerted and / or exerted on the at least one carriage 102 which points in a direction from the second passage wall 19 to the at least one carriage 102. Preferably, the at least one tensioning drive 104 is arranged between a first support surface 103 of the at least one carriage 102 and the second passage wall 19. The at least one tensioning drive 104 is preferably designed as at least one actuating body 104 that can be acted upon and / or acted upon by a pressure medium. Such a pressure medium is for example a hydraulic medium or a pneumatic medium, in particular air. The at least one tensioning drive 104 is further preferably designed as at least one tensioning hose 104. The at least one adjusting body 104 and preferably the at least one tensioning hose 104 can preferably be acted upon by pressures of up to 10 bar and more. However, the at least one tensioning drive 104 can also be designed as at least one hydraulic cylinder 104 and / or at least one pneumatic cylinder 104 and / or at least one electric motor 104. The at least one tensioning drive 104 is preferably supported against a relative to the plate cylinder 07 rigidly arranged component or a part of the plate cylinder 07 itself, for example, the second channel wall 19. If in Previous or hereinafter of the at least one tensioning hose 104 is mentioned, so it is also generally meant at least one actuatable and / or acted upon by a pressure means actuating body 104.

Preferably, at least one return element 106 is arranged, for example at least one spring 106 designed as a return spring 106; 107. The at least one return element 106 causes a restoring force on the at least one carriage 102, which is oriented counter to the clamping direction E. The at least one return element 106 is supported in one embodiment against a relative to the plate cylinder 07 rigidly arranged component or a part of the plate cylinder 07 itself. Preferably, however, the at least one restoring element 106 is identical to the supporting body 107 formed as a spring 107, which is supported both on the at least one first clamping device 21 and on the at least one second clamping device 61 and by means of which the at least one first clamping device 21 against the first Channel wall 18 is pressed. As long as the at least one tensioning drive 104 is deactivated, the at least one carriage 102 is arranged in a first, also peripheral position closer to the second channel wall 19 position of the at least one carriage 102, in particular because of the at least one restoring element 106 on the at least one carriage applied restoring force.

The at least one tensioning device 101 preferably has at least one fixing device 109, by means of which the at least one second clamping device 61 can be fixed in its position and in particular while maintaining a tension of the pressure plate 73, in particular at least with respect to movements of the at least one carriage 102 onto the second channel wall 18 to. In the following, two different embodiments of the fixing device 109 will be described.

A first embodiment of the fixing device 109 will be described below. In the first embodiment, the fixing device 109 at least one preferred adjustable rear spacer 131, which is preferably designed as at least one rear adjusting screw 131. The at least one rear spacer 131 is preferably mounted in the at least one carriage 102 and in the at least one rear clamping device 61, in particular in the rear main body 71, by means of a bearing which preferably has at least one thread or is formed as a thread It is also possible to support the at least one rear spacer 131 by means of a bearing in a component of the cylinder bale 12 or a component rigidly arranged relative to the cylinder bale 12. The at least one rear spacer 131 is movable relative to the at least one carriage 102, in particular in its relative position to the at least one carriage 102 adjustable, for example by a screwing movement in the at least one thread. The at least one rear spacer 131 is preferably movable together with the at least one carriage 102. The at least one rear spacer 131 can be arranged 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. In the at least one extended position of the at least one rear spacer 131, the at least one rear spacer 131 preferably protrudes further in a direction towards the second channel wall 19 beyond a rear edge surface 132 of the at least one carriage 102 facing the second channel wall 13 than in FIG the retracted position.

If the at least one rear spacer 131 is mounted by means of a bearing in a component of the cylinder bale 12 or a component rigidly arranged relative to the cylindrical bale 12, the at least one rear spacer 131 is in particular in at least one retracted position and in at least one and preferably several extended Positions relative to the cylindrical bale 12 can be arranged. In the at least one extended position of the at least one rear spacer 131, the at least one rear spacer 131 then preferably protrudes beyond the in a direction to be pointed towards the at least one carriage 102 the at least one carriage 102 facing the second channel wall 13 addition than in the retracted position.

The at least one return element 106 causes, as already described, a restoring force on the at least one carriage 102, which is oriented counter to the clamping direction E. If no opposing forces act, the at least one carriage 102 is thus pressed against the second channel wall 19. Depending on the position of the at least one rear spacer 131, however, the at least one carriage 102 is prevented from coming closest to the second channel wall 19, and in particular to its peripheral position. If the at least one rear spacer 131 is in the retracted position and the at least one rear spacer 131 and / or the at least one carriage 102 itself are in contact with the second channel wall 19, the at least one carriage 102 is farther from the at least one front one Clamping device 21 disposed away as if the at least one rear spacer 131 is in an extended position and in contact with the second channel wall 13. Accordingly, even the smallest distances between the at least one front clamping opening 27 and the at least one rear clamping opening 67 behave. A pressure plate 73 which is clamped in the at least one front clamping device 21 and in the at least one rear clamping device 61 and placed around the cylindrical bale 12 is thus deactivated Clamping drive 104 depending on the position of the at least one rear spacer 131 more or less tensioned. The fixing device 109 in the first embodiment therefore counteracts the clamping force of the pressure plate 73 and / or the restoring force of the at least one restoring element 106 and thus fixes the at least one carriage 102 and thus the at least one rear clamping device 61.

The fixing device 109 in the first embodiment is preferably operated such that a pressure plate 73 clamped both in the at least one front clamping device 21 and in the at least one rear clamping device 61 is tensioned by the at least one tensioning drive 104 is activated, for example by the pressure element is acted upon and / or acted actuator 104, in particular the tensioning tube 104 is subjected to a pressure and expands so that it moves the at least one carriage 102. In this case, the at least one rear spacer 131 is initially arranged in the retracted position relative to the at least one carriage 102. The at least one carriage 102 and thus the entire at least one rear clamping device 61 moves toward the at least one front clamping device 21. As a result, the pressure plate 73 wound around the plate cylinder 07 is tensioned. The at least one carriage 102 preferably moves so far that a desired tension of the pressure plate 73 is reached or more preferably at least slightly exceeded. Subsequently, the at least one rear spacer 131 is moved from the retracted position to a defined extended position. Subsequently, the tensioning drive 104 is deactivated, for example by reducing the pressure in the tensioning hose 104, for example to ambient pressure, in particular atmospheric pressure. Optionally, the at least one carriage 102 again moves towards the second channel wall 19 until the at least one rear spacer 131 contacts the second channel wall 19 at respectively one and preferably exactly one spacer contact point 133 and thereby stops the at least one slide 102. Alternatively, the at least one carriage 102 contacts the at least one spacer 131 mounted in the cylinder bale 12 to stop the at least one carriage 102.

The rear clamping device 61 is in this state, as already described, thereby held in its position that the restoring force of the at least one restoring element 106 and / or the voltage of the pressure plate 73, the at least one carriage 102 and thus the at least one rear clamping device 61 against the second channel wall 19 presses, but in a fixed by the position of the at least one rear spacer 131 distance. For this, no drive must remain permanently activated and, in particular, no hose must be permanently pressurized. The at least one tensioning drive 104, the at least one rear spacer 131 and the at least one rear adjusting element 64 are preferably supported against a same component of the carriage 102 and the at least one rear clamping device 62, more preferably against the rear body 71. Operations of at least one tensioning drive 104, the at least one rear spacer 131 and the at least one rear adjusting 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. The exact position of the at least one rear spacer 131 thus defines a maximum tension force acting on the tensioned pressure plate 73. Preferably, a plurality, more preferably at least four of the described rear spacers 131 are arranged spaced from one another in the axial direction A. In a preferred embodiment, the at least one rear spacer 131 is adjustable in position by means of at least one drive 134 designed as a distance drive 134. The at least one distance drive 134 is preferably designed as at least one electric motor 134. The at least one distance drive 134 may also be designed as a pneumatic and / or hydraulic drive 134. The at least one distance drive 134 and / or the at least one rear spacer 131 further preferably has at least one distance sensor, which detects a position of the at least one distance drive 134, for example a rotational angle position of the at least one electric motor and / or the one position of the at least one rear spacer 131 recorded. Preferably, the at least one distance sensor is connected to the machine control and / or the at least one distance drive 134 is connected to the machine control. Alternatively or additionally, a position of the at least one spacer 131 is 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 variably adjustable rear stop actuator 112, for example, at least one rear stop screw 112. The at least one rear stop actuating element 112 preferably has at least one stop gear 113, for example in order to enable a finer adjustment of the position of the at least one rear stop actuating element 112. The at least one rear stop actuating element 112 is preferably mounted in at least one bearing 122, which is designed, for example, as a bearing block 122. Preferably, the at least one rear stop actuating element 112 is connected to the at least one bearing 122 via at least one thread. The at least one bearing 122 is preferably arranged stationary relative to the cylindrical bale 12, for example formed as part of the cylinder bale 12. The at least one stop body 111 is preferably arranged on the at least one carriage 102 and can be moved together with it. The at least one rear stop actuating element 112 is preferably arranged delimiting the maximum travel of the at least one carriage 102. The maximum travel of the at least one carriage 102 is then preferably limited at one end by the at least one rear stop actuator element 112 and at another end by the second channel wall 19. By changing the position of the at least one rear stop actuating element 112 with respect to the clamping direction E, the maximum travel of the at least one carriage 102 is adjustable, in particular extendible and / or shortenable.

Preferably, at least one carriage clamping element 114 is arranged on the at least one carriage 102. The at least one carriage clamping element 114 is preferably arranged to be movable relative to the at least one carriage 102 by means of at least one drive 116 designed as a slide-release drive 116. By means of the at least one carriage release drive 116, the at least one carriage clamping element 114 with a first carriage clamping surface 117 of the at least one channel 13 in and / or outside Contactable. In a fixed position of the at least one carriage 102, the at least one carriage release drive 116 is supported on the one hand on the at least one carriage 102 and thus on the at least one rear clamping device 61, and on the other hand the at least one carriage release drive 116 is supported on the at least one carriage clamping element 114 first carriage clamping surface 117 of the channel 13 from. The at least one carriage 102 and thus the at least one second clamping device 61 preferably again supports itself on one of the first carriage clamping surface 117 of the channel 13 opposite the second carriage clamping surface 118 of the channel 13. As a result, the at least one carriage 102 is fixed in the channel 13. Preferably, the at least one carriage release drive 116 is constructed analogously to the principle of the at least one front clamping device 21 and / or the at least one rear clamping device 61.

For this purpose, the at least one carriage release drive 116 preferably has at least one and more preferably at least two carriage contact elements 119. The at least one Schlittenanpresselement 119 is preferably formed as at least one carriage leaf spring 119, more preferably as at least one front carriage spring assembly 119, which consists of several, in particular flat abutting leaf springs 119. The at least one carriage release drive 116 preferably has at least one carriage release plate 121. The at least one carriage release plate 121 is preferably designed as at least one carriage release hose 121, which is filled with a fluid and / or can be filled, for example with compressed air. Preferably, the compressed air in an interior of the at least one Schlittenlöseschlauchs 121 with a pressure of up to 10 bar or more acted upon and / or acted upon. The at least one carriage release plate 121 can also be designed as at least one hydraulic cylinder 121 and / or at least one pneumatic cylinder 121 and / or at least one electric motor 121.

Irrespective of the design of the at least one carriage freesteller 121, activation of the at least one carriage freestanding plate 121 preferably effects shortening of the carriage at least one Schlittenanpresselements 119 and preferably the at least two Schlittenanpresselemente 119 in at least one carriage clamping direction F, which is further preferably oriented parallel to the second clamping direction C. This is done for example by means of a deflection of the at least one Schlittenanpresselements 119 and preferably by means of mutually opposite deflections of the at least two Schlittenanpresselemente 119. This causes movement of the at least one Schlittenklemmelements 114 away from the first carriage clamping surface 117 and thus releasing the at least one carriage 102th Das at least one, and preferably the at least two carriage press members 119 are preferably flexibly connected to the at least one carriage 102, more preferably such that they can not be removed therefrom but still be movable relative thereto, in particular during their deformation. The at least one and preferably the at least two carriage pressing members 119 are preferably flexibly connected to the at least one carriage clamping element 114, more preferably such that they can not be removed therefrom but are still movable relative thereto, in particular during their deformation. In particular, the at least one carriage clamping element 114 is thus flexibly connected to the at least one carriage pressing element 119 such that a shortening of the at least one carriage pressing element 119 necessarily causes the at least one carriage clamping element 114 to move against the carriage clamping direction F and thus to release the at least one carriage clamping element 114 at least one carriage 102 and thus the at least one fixing device 109 causes.

The at least two Schlittenanpresselemente 119 are preferably, in particular apart from a deflection or curvature, arranged parallel to each other and extend in the axial direction A and substantially in an orthogonal thereto 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 are constantly under a more or less large bias. This is preferably the case regardless of a state of the Schlittenlöseschlauchs 121 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 Schlittenlöseschlauch 121, enough space available to complete to be relaxed. The at least one sled release tube 121 is arranged between the at least two Schlittenanpresselementen 119 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 pivotally with each other and / or with the main body 71 of the at least one rear Clamping device 61 and / or connected to the at least one carriage clamping element 114. The at least one carriage release hose 121 is arranged, viewed at least from a preferably axial direction A, 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 attached to the main body 71 of the at least one rear clamping device 61, 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 attached to the carriage clamping element 114, more preferably by means of at least one of the at least two connecting elements. On both sides of the Schlittenlöseschlauchs 121 at least one clip element is arranged to prevent removal of ends of the at least two Schlittenanpresselemente 119 from each other over a maximum distance. This causes that upon inflation of the Schlittenlöseschlauchs 121, the at least two Schlittenanpresselemente 119 not only swing away from each other, but bulge away from the hose to the outside, since their ends are not from the ends of the adjacent Remove carriage pressing elements 119. Preferably, at least one clip element is formed by the at least one carriage clamping element 114. Preferably, at least one clip element is formed by the base body 71 of the at least one rear clamping device 61

By virtue of the formed curvature, however, the at least two carriage pressing elements 119 shorten, for example, with respect to a direction from one connecting element through the carriage-releasing hose 121 to another connecting element. In particular, a straight-line distance between two ends of one and the same Schlittenanpresselements 119 is shortened. As a result, the at least one carriage clamping element 114 moves relative to the main body 71 of the at least one rear clamping device 61 and in particular to this and the clamping is released. For example, the at least two connecting elements are formed as connecting pins, which protrude through slots of the at least two Schlittenanpresselemente 119 and are connected at its two ends respectively to the main body 71 of the at least one rear clamping device 71 or with the at least one carriage clamping element 114.

Upon deactivation of the at least one carriage free plate 121, a restoring force of the at least one carriage actuating element 119 causes movement of the at least one carriage clamping element 114 towards the first carriage clamping surface 117 and thereby clamping the at least one carriage 102 and the rear body 71 and thus the at least one fixing device 109. Such a deactivation of the at least one front slide plate 121 consists, for example, in a lowering of the pressure in the interior of the slide tube hose 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 109th dissolved or clamped and regardless of where the at least one carriage 102 is located. In particular, the carriage leaf springs 119, more preferably the at least one carriage spring package 119 are slightly bent and biased at all times.

The fixing device 109 in the second embodiment is preferably operated such that a pressure plate 73 clamped both in the at least one front clamping device 21 and in the at least one rear clamping device 61 is first tensioned by activating the at least one tensioning drive 104, for example by the Clamping hose 104 is pressurized and expands to move the at least one carriage 102. In this case, the fixing device 109 is initially released, for example by the carriage release tube 121 is pressurized and thereby the two carriage spring assemblies 119 deformed such that the at least one carriage clamping element 114 is withdrawn. The at least one carriage 102 and thus the entire at least one rear clamping device 61 moves toward the at least one front clamping device 21. As a result, the pressure plate 73 wound around the plate cylinder 07 is tensioned. The at least one carriage 102 preferably moves so far until the at least one stop body 111 contacts the at least one rear stop actuating element 112 at a stop contact 123 and thereby stops the at least one carriage 102. The at least one rear stop actuating element 112 is preferably already arranged in a position which ensures an optimum position of the at least one carriage 102 as soon as the at least one stop body 111 contacts the at least one rear stop actuating element 112. Then, the fixing device 109 is clamped, for example, by the pressure in the Schlittenlöseschlauch 121 is reduced so much that the Schlittenfederpakete 119 relax and thereby press the at least one carriage clamping element 114 against the first carriage clamping surface 117. As soon as the fixing device 109 is clamped, the tensioning drive 104 is deactivated, for example by reducing the pressure in the tensioning hose 104, for example to ambient pressure, in particular atmospheric pressure. The rear clamping device 61 is held in its position in this state in that the fixing device 109 clamps the at least one carriage 102 and thus the at least one rear clamping device 61 in its position in the channel 13. For this, no drive must remain permanently activated and, in particular, no hose must be permanently pressurized. The at least one tensioning drive 104, the at least one carriage free plate 121 and the at least one rear adjusting element 64 are preferably supported against a same component 71 of the carriage 102 and the at least one rear clamping device 62, more preferably against the rear body 71. Actuations of the at least one tensioning drive 104, the at least one carriage free plate 121 and the at least one rear actuating element 64 are preferably independently executable.

The exact position of the at least one rear stop actuator element 112 defines the maximum travel of the at least one carriage 102. The exact position of the at least one rear stop actuator element 112 thus defines a maximum tension force acting on the tensioned pressure plate 73. Preferably, a plurality, more preferably at least two and even more preferably at least four of the rear stop actuating elements 112 described are arranged spaced from one another in the axial direction A. In a preferred embodiment, the at least one rear stop actuating element 112 is adjustable in its position by means of at least one drive designed as a stop drive.

Preferably, the at least one stop body 111 is movably arranged between a stop position and a passing position, preferably in a direction orthogonal to the tensioning direction E, for example in the axial direction A. In the stop position, the at least one stop body 111 is at least opposite to the tensioning direction E a rear stop actuator element 112. The interaction then takes place as described above. In the passing position, the at least one stop body 111 is located outside an extension of the at least one rear stop element 112 in the tensioning direction E. As long as the at least one stop body 111 is in the passing position, the at least one stop body 111 thus does not limit the travel of the at least one Schlittens 102. This allows a greater travel than the set for clamping operations maximum travel of the at least one carriage 102 without the at least one rear stop actuator 112 would have to be set differently. This facilitates placement of the pressure plate 73 on the plate cylinder 07 and thus allows a particularly effective introduction of the pressure plate 73 in the at least one rear clamping device 61st

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

More preferably, the pressure in the at least one front clamping release hose 24 is reduced, in particular until the at least one front clamping release hose 24 is under an ambient pressure, in particular atmospheric pressure. As a result, the at least one front clamping release hose 24 preferably shrinks. The at least one front pressing element 23 preferably uses the space that is freed and stretches and preferably the two front pressing elements 23 extend and move toward one another in some opposite direction. Preferably, the at least one radially inner front clamping element 26 moves towards the at least one radially outer front clamping element 22 and the front clamping gap 27 is closed. In a support process, which is part of the third process, for example, the pressure plate 73 is preferably placed on the lateral surface 124 of the plate cylinder 07. This happens, for example, by the plate cylinder 07 is pivoted about its axis of rotation 11 and thereby, preferably by means of a Support device, such as a pressure roller, the pressure plate 73 is pressed against the lateral surface 124 of the plate cylinder 07. Optionally, at least one base can be arranged between the lateral surface of the plate cylinder 07 and the pressure plate 73, for example to compensate for deviations of the diameter from an ideal diameter.

Before and / or at the same time and / or afterwards, the at least one carriage 102 is preferably moved from its peripheral position along the clamping path about an insertion path onto the at least one front clamping device 21 and the first channel wall 18 to a central or inner position. The insertion distance is preferably between 10 mm and 30 mm, more preferably at least 15 mm and even more preferably between 15 mm and 25 mm long. For this purpose, the at least one drive 104 designed as a tensioning drive 104 is activated. More preferably, the at least one tensioning hose 104 is acted upon by compressed air, which is under a pressure of preferably between 1 bar and 10 bar, more preferably between 4 bar and 6 bar. Since the at least one tensioning hose 104 is preferably supported both on the second channel wall 19 and on the at least one slide 102, the at least one slide 102 is thus preferably moved. Following the plate cylinder is preferably rotated about its axis of rotation 11 while the pressure plate 73 is placed on the lateral surface. In this case, it is preferably pressed against this lateral surface of the at least one plate cylinder 07 by means of at least one pushing means, for example a spinning roller.

In other words, the rear end 76 of the pressure plate 73 is brought into an effective range of the at least one rear clamping device 61 in its peripheral position. Subsequently, the at least one carriage 102 is preferably moved from its central or inner position along the clamping path about the insertion path to the second channel wall 19 in its peripheral position. For this purpose, the at least one tensioning drive 104 is preferably deactivated. More preferably, the pressure in the at least one tensioning hose 104 is reduced, in particular until the at least one front tensioning hose 104 is under an ambient pressure, in particular atmospheric pressure.

Preferably, the rear end 76 of the pressure plate 73 is at least partially enclosed by the at least one rear clamping gap 67 of the at least one rear clamping device 61, while the at least one carriage 102 is moved along the clamping path from its inner position to the second channel wall 19 to its edge position , It is equally possible to change the order of the fourth method procedure and of the parts of the fifth method procedure, for example to open the at least one rear clamping element 61 only when the carriage 102 is already in its central or inner position.

A sixth operating state, which is also referred to as the rear inserting state of the plate cylinder 07, preferably differs from the fifth operating state only in that the rear end 76 of the pressure plate 73 fits into the at least one rearward one Clamping device 61 and in particular in the rear clamping gap 67 is inserted and that the at least one carriage 102 is in the peripheral position.

In a sixth process operation, which is also called the rear clamping process, the at least one rear clamping device 61 and in particular the rear clamping gap 67 is closed, thereby trapping the rear end 76 of the pressure plate 73 in the at least one rear clamping device 61 and in particular in the rear clamping gap 67 , For this purpose, the at least one rear adjusting element 64 is preferably deactivated. More preferably, the pressure in the at least one rear clamping solution hose 64 is reduced, in particular until the at least one rear clamping solution hose 64 is under an ambient pressure, in particular atmospheric pressure. The at least one rear contact element 63 preferably uses the space released and stretches and preferably the two rear contact elements 63 extend and move towards each other at least partially in the opposite direction. Preferably, the at least one radially inner rear clamping element 66 moves toward the at least one radially outer rear clamping element 62 and the rear clamping gap 67 is closed.

A seventh operating state of the plate cylinder 07, which is also called the rear clamping state, differs from the sixth operating state preferably only in that the at least one rear clamping device 61 and in particular the rear clamping gap 67 is closed and that the rear end 76 of the pressure plate 73 in the at least one rear clamping device 61 and in particular in the rear clamping gap 67 is clamped and that the at least one rear control element 64 is deactivated and more preferably that the at least one rear Klemmlöseschlauch 64 is under an ambient pressure, in particular atmospheric pressure and that the at least one rear contact 63 less is strongly bent.

A seventh process operation, which is also called clamping operation, depends on the embodiment of the fixing device 109. The seventh process operation is preferably carried out in connection with the fixing device 109 in the first embodiment, as described below. First, in a first portion of the tensioning operation, the pressure plate 73 is preferably prepared by moving the at least one carriage 102 towards the at least one front clamping device 21 and the first channel wall 18, more preferably further than providing it with a pressure plate 73 is. In particular, the at least one carriage 102 is moved away from the second channel wall 19. Preferably, the pressure plate 73 is thereby tensioned with a first force. Preferably, the pressure plate 73 is thereby stretched with more than it is provided for a printing operation with this pressure plate 73. For this purpose, the at least one tensioning drive 104 is activated. More preferably, the at least one tensioning hose 104 is acted upon by 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 tensioning hose 104 is preferably supported both on the second channel wall 19 and on the at least one carriage 102, the at least one carriage 102 is thus moved. The pressure is preferably selected to be higher than that provided in the rear insertion process, because it is necessary to work against the stress built up in the pressure plate 73. Subsequently, in a second section of the clamping operation, the pressure plate 73 is relieved again by the at least one carriage 102 is moved back to the second channel wall 19, more preferably in its peripheral position. For this purpose, at least one tensioning drive 104 is deactivated. More preferably, the pressure in the at least one tensioning hose 104 is reduced, in particular until the at least one front tensioning hose 104 is under a lower pressure, for example an ambient pressure, in particular atmospheric pressure.

Following this, in a third section of the tensioning process, the at least one slide 102 is preferably moved toward the at least one front clamping device 21 and the first channel wall 18, more preferably further than for a printing operation is provided. Preferably, the pressure plate is tensioned with a second force. Preferably, the second force is the same size as the first force. The preferred fast clamping beyond the measure provided in the printing operation ensures that a clamping force can affect the pressure plate 73 along the entire circumference of the pressure plate 73 and not only an edge region is influenced, in particular stretched, by the tension force due to static friction. For this purpose, in turn, the at least one tensioning drive 104 is activated. More preferably, the at least one tensioning hose 104 is acted upon by compressed air, which is under a pressure of preferably between 2 bar and 8 bar, more preferably between 2 bar and 5 bar for a pressure plate 73 with a support plate made of aluminum and between 3 bar and 6 bar for a printing plate 73 with a support plate made of steel. Preferably, the pressure plate 73 and in particular its rear end 76 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 61. The at least one carriage 102 is initially arranged in an intermediate state closer to the first channel wall 18 and the at least one first clamping device 21, as provided in the printing operation. Now, the at least one rear spacer 131 is set to a position relative to the at least one carriage 102, which defines a certain distance of the at least one rear clamping device 61 of the second channel wall 19, which ensures a pressure of the pressure plate 73 provided in the printing operation. For this purpose, the at least one rear adjusting screw 131 is preferably rotated relative to the at least one carriage 102 and / or relative to the cylindrical bale 12 about its threaded axis, more preferably by means of the at least one drive 134 designed as a distance drive 134. Subsequently, the pressure plate 73 becomes partially again relieved by the at least one carriage 102 is moved back to the second channel wall 19, preferably until the at least one rear spacer 131 comes into contact with the second channel wall 19 at the at least one distance contact point 133. For this purpose, at least one tensioning drive 104 is preferably at least partially deactivated. More preferably, the pressure in the at least one tensioning hose 104 is reduced, in particular until the at least one tensioning hose 104 is under a lower pressure than before, for example under an ambient pressure, in particular atmospheric pressure. The pressure plate 73 is now stretched and the plate cylinder 07 is in an eighth operating state in a first embodiment. In particular, in the first section of the clamping operation and in the third section of the clamping operation, the pressure inside the tensioning hose 104 is at least temporarily greater than in the second section of the tensioning operation. Preferably, a third force, with which the pressure plate 73 is tensioned in the eighth operating state, is smaller than the first force and / or the second force, with which the pressure plate 73 is tensioned during the first section and / or during the third section of the tensioning process becomes.

The eighth operating state in the first embodiment, which is also called the clamping state or printing operating state, preferably differs from the seventh operating state when using the fixing device 109 in the first embodiment only in that the at least one carriage 102 has a greater distance from the second channel wall 19 as in the seventh operating state, and that the at least one carriage 102 is spaced from the first channel wall 18 by a smaller distance than in the seventh operating state and the at least one rear spacer 131 is changed in position relative to the at least one carriage 102 such that the at least one rear spacer 131 with respect to the circumferential direction D is arranged relative to the at least one carriage 102 toward the rear channel wall 19 as in the seventh operating state and that the pressure plate 73 is stretched on the lateral surface 124 of the plate cylinder 07. In this eighth operating state, the plate cylinder 07 is ready for a printing operation and / or the plate cylinder is in the printing operation.

On the other hand, the seventh process operation, which is also called clamping operation, is preferably carried out in connection with the fixing device 109 in the second embodiment, as described below. First, in a first section of the Tensioning preferably prepares the pressure plate 73 by moving the at least one carriage 102 toward the at least one front clamping device 21 and the first channel wall 18, more preferably further than is intended for a printing operation. In particular, the at least one carriage 102 is moved away from the second channel wall 19. For this purpose, the fixing device 109 is preferably first achieved by activating the at least one drive 116, which is preferably designed as a slide-release drive 116. For this purpose, for example, the pressure in the Schlittenlöseschlauch 121 is increased to such an extent that the Schlittenfederpakete 119 deform and thereby the at least one carriage clamping element 114 detaches from the first carriage clamping surface 117. Preferably, the at least one stop body 111 is moved into its passing position in order to facilitate the movements of the at least one slide 102 described below, more preferably by means of the drive designed as at least one positioning drive. Now the at least one tensioning drive 104 is activated. More preferably, the at least one tensioning hose 104 is acted upon by 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 tensioning hose 104 is supported both on the second channel wall 19 and on the at least one carriage 102, the at least one carriage 102 is thus moved. The pressure is preferably selected to be higher than that provided in the rear insertion process, because it is necessary to work against the stress built up in the pressure plate 73.

Subsequently, in a second section of the clamping operation, the pressure plate 73 is relieved again by the at least one carriage 102 is moved back to the second channel wall 19, more preferably in its peripheral position. For this purpose, at least one tensioning drive 104 is deactivated. More preferably, the pressure in the at least one tensioning hose 104 is reduced, in particular until the at least one front tensioning hose 104 is under a lower pressure, for example an ambient pressure, in particular atmospheric pressure. Then, the at least one stop body 111 is preferably first moved into the stop position, more preferably by means of at least one drive designed as a positioning drive. Previously and / or subsequently and / or at the same time, the at least one rear stop actuating element 112 is preferably moved relative to the cylindrical bale 12 with respect to the clamping direction E into a stop target position, more preferably by means of the at least one drive designed as a stop drive. More preferably, the at least one rear stop screw 112 is rotated about its threaded axis. As a result, as described, the maximum travel of the at least one carriage 102 and thus the maximum clamping force acting on the tensioned pressure plate 73 are determined.

Now, in a third section of the clamping operation, the at least one carriage 102 is preferably moved towards the at least one front clamping device 21 and the first channel wall 18 and, in particular, away from the second channel wall 19 until the at least one rear stop actuating element 112 contacts the at least one stop body 111 , A continuation of the movement of the at least one carriage 102 is then not possible because of the contact of the at least one rear stop actuating element 112 with the at least one stop body 111. For this purpose, in turn, the at least one tensioning drive 104 is activated. More preferably, the at least one tensioning hose 104 is acted upon by compressed air, which is under a pressure of preferably between 2 bar and 8 bar, more preferably between 2 bar and 5 bar for a pressure plate 73 with a support plate made of aluminum and between 3 bar and 6 bar for a printing plate 73 with a support plate made of steel.

Subsequently, the fixing device 109 is clamped, for example, by the pressure in the Schlittenlöseschlauch 121 is reduced so that the Schlittenfederpakete 119 relax and thereby press the at least one carriage clamping element 114 against the first carriage clamping surface 117, for example, to ambient pressure, in particular atmospheric pressure. As soon as the fixing device 109 is clamped, the tensioning drive 104 is deactivated, for example by reducing the pressure in the tensioning hose 104, for example to ambient pressure, in particular atmospheric pressure. The back Clamping device 61 is held in its position in this state in that the fixing device 109 clamps the at least one carriage 102 and thus the at least one rear clamping device 61 in its position in the at least one channel 13. The pressure plate 73 is now stretched and the plate cylinder 07 is in an eighth operating state in a second embodiment.

The eighth operating state in the second embodiment, which is also called the clamping state or printing operating state, preferably differs from the seventh operating state when using the fixing device 109 in the second embodiment only in that the at least one carriage 102 has a greater distance from the second channel wall 19 as in the seventh operating state and that the at least one carriage 102 from the first channel wall 18 has a smaller distance than in the seventh operating state and that the at least one stop body 111 contacts the at least one rear stop actuator 112 and that the pressure plate 73 on the lateral surface 124 of Plate cylinder 07 is tensioned. In this eighth operating state, the plate cylinder 07 is ready for a printing operation and / or the plate cylinder is in the printing operation.

Regardless of the embodiment of the clamping operation, the pressure plate 73 and in particular its rear end 76 preferably remains clamped in the rear clamping device 61 at least from the beginning of the first portion of the tensioning operation to the end of the third portion of the tensioning operation. Regardless of the embodiment of the clamping operation, the at least one carriage 102 is preferably moved toward the at least one front clamping device 21 and the first channel wall 18 by means of a first force in the first section of the clamping operation, thereby tensioning the pressure plate 73, which is preferably the same size. such as a second force with which, in the third section of the clamping operation, the at least one carriage 102 moves toward the at least one front clamping device 21 and the first channel wall 18, thereby tensioning the pressure plate 73. Preference is given to a first central or first inner The situation in which the at least one carriage 102 stops in the first portion of the tensioning operation, closer to the second channel wall 19 as a second central or second inner layer in which the at least one carriage 102 stops in the third portion of the tensioning operation. This is due to the fact that the pressure plate 73 settles in the first portion of the tensioning process, thereby loosening tension and reducing any voids, so that the pressure plate 73 is set in total.

Regardless of the embodiment of the fixing device 109, at least one test print is preferably carried out in at least one eighth process operation. A copy of a printed product, for example a sheet 09, is printed for this proof. On the basis of the resulting print image is evaluated whether and how far the plate tension should be changed and / or if and how far an inclined position of the pressure plate 73 should be changed on the plate cylinder 07 and / or if and how far a convex and / or concave deformation of front end 74 of the pressure plate 73 and / or the rear end 76 of the pressure plate 73 should be changed. Should the print image already be perfect, all settings of the tensioning device 101 are retained. This process is preferably repeated as many times as necessary. More preferably, no more than this a trial print is necessary to set a complete and final adjustment of the plate cylinder 07 and even more preferably all cooperating with a common transfer cylinder 06 plate cylinder 07.

Otherwise, in at least one ninth process operation, adjustments of the settings of the tensioning device 101 are carried out in accordance with the evaluation in the eighth process operation. Regardless of the type of adjustments, the fixing device 109 is first released again and the pressure plate 73 is at least partially relaxed.

When using the first embodiment of the fixing device 109, the at least one carriage 102 is first removed from the second channel wall 19 and moved toward the first channel wall 18 and the at least one front clamping device 21 in the ninth process operation. Preferably, the at least one tensioning drive 104 is activated for this purpose. More preferably, the at least one tensioning hose 104 is acted upon by compressed air, which is under a pressure of preferably between 3 bar and 10 bar, until the at least one carriage 102 carries out said movement. Then, the at least one carriage 102 is stopped. Now, the at least one rear spacer 131 is set to a position relative to the at least one carriage 102 and / or relative to the cylindrical bale 12, the wall 19 allows a smaller distance of the at least one rear clamping device 61 of the second channel. For this purpose, the at least one rear adjusting screw 131 is preferably rotated relative to the at least one carriage 102 and / or relative to the cylindrical bale 12 about its threaded axis, more preferably by means of the at least one distance drive 134. Subsequently, the pressure plate 73 is relieved again by the at least a carriage 102 is again moved towards the second channel wall 19, preferably until the at least one carriage 102 is again in its peripheral position and / or until the at least one rear spacer 131 engages with the second channel wall 19 and / or the at least one carriage 102 the at least one contact pad 133 comes into contact. For this purpose, the at least one tensioning drive 104 is preferably at least partially deactivated. More preferably, the pressure in the at least one tensioning hose 104 is reduced, in particular until the at least one tensioning hose 104 is under a lower pressure than before, for example under an ambient pressure, in particular atmospheric pressure.

When using the second embodiment of the fixing device 109, the at least one tensioning drive 104 is preferably activated in the ninth method operation. More preferably, the at least one tensioning hose 104 is acted upon by compressed air, which is under a pressure of preferably between 3 bar and 10 bar. The least a carriage 102 and in particular the at least one rear stop actuating element 112 is now pressed by the at least one tensioning drive 104 with a sufficiently large force against the at least one stop body 111. Now, the fixing device 109 is preferably first of all released, for example by increasing the pressure in the carriage release hose 121 to such an extent that the carriage spring packs 119 deform and thereby detach the at least one carriage clamping element 114 from the first carriage clamping surface 117. Following the pressure plate 73 is relieved again by the at least one carriage 102 is moved back to the second channel wall 19, preferably until the at least one carriage 102 is again in its peripheral position and / or until the at least one rear spacer 131 with the second channel wall 19 at the at least one distance contact point 133 comes into contact. For this purpose, at least one tensioning drive 104 is preferably at least partially deactivated. More preferably, the pressure in the at least one tensioning hose 104 is reduced, in particular until the at least one tensioning hose 104 is under a lower pressure than before, for example under an ambient pressure, in particular atmospheric pressure.

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

In a partial process for correcting an inclined position of the pressure plate 73 and / or in a partial process for correcting a convex and / or concave deformation of the front end 74 of the pressure plate 73, at least one of the at least two and preferably the at least two second support locations 34; 36 set. For this purpose, the at least two are preferred as the front adjusting screws 39; 41 formed front contact body 39; 41 in their position relative to the at least one front clamping device 21, in particular to the at least one radially outer front clamping element 22 and / or adjusted relative to the cylindrical bale 12. Further preferred is at least one and in particular the at least two front adjusting screws 39; 41 about its threaded axis relative to the at least one front Clamping device 21 and / or rotated relative to the cylindrical bale 12, more preferably by means of the at least one as a front biasing drive 43; 44 formed drive 43; 44. Since preferably at all support points 33; 34; 36, the first channel wall 18 and the at least one front clamping device 21, in particular the at least one radially outer front clamping element 22, in particular in the form of the bulge and the at least two front contact body 39; 41 are in contact with each other, by adjusting the at least two second support points 33; 34 a deflection and / or an inclined position of the at least one first clamping device 21 relative to the first channel wall 18 is influenced.

If, for example, the at least two front adjusting screws 39; 41 moves at its setting relative to the bulge of the at least one first clamping device 21 away from the first channel wall 18, so form the first channel wall 18 facing ends of the at least two front adjusting screws 39; 41 together with the preferably with respect to the axial direction A arranged therebetween bulge no straight line. By acting forces, for example due to the formed as a spring 107 supporting body 107 and / or the tensioned pressure plate 73, then at least the at least one front clamping device 21 is deformed such that axially outer portions of the at least one front clamping device 21 and the tensioned pressure plate 73 stronger first channel wall 18 are drawn, as an axially central region of the at least one first clamping device 21 and the clamped pressure plate 73. The spanned pressure plate 73 is thus deformed convexly at its front end 74. Such a convex deformation at the front end 74 of the pressure plate 73 preferably propagates through the entire pressure plate 73 in the circumferential direction D and is further preferably set to oppose a concave deformation of the printed image on the pressure plate 73.

If, for example, the at least two front adjusting screws 39; 41 at their setting relative to the bulge of the at least one first clamping device 21st moved towards the first channel wall 18, so the first channel wall 18 facing ends of the at least two front adjusting screws 39; 41 together with the preferably with respect to the axial direction A arranged therebetween bulge no straight line. By acting forces, for example due to the formed as a spring 107 supporting body 107 and / or the tensioned pressure plate 73, then at least the at least one front clamping device 21 is deformed such that axially outer regions of the at least one front clamping device 21 and the tensioned pressure plate 73 less are drawn to the first channel wall 18, as an axially central region of the at least one first clamping device 21 and the clamped pressure plate 73. The spanned pressure plate 73 is thus deformed concave at its front end 74. Such a concave deformation at the front end 74 of the pressure plate 73 preferably propagates through the entire pressure plate 73 in the circumferential direction D and is further preferably adjusted so that it counteracts a convex deformation of the printed image on the pressure plate 73.

If, for example, the at least two front adjusting screws 39; 41 in their setting relative to the bulge of the at least one first clamping device 21 moves opposite to each other, so the first channel wall 18 facing ends of the at least two front adjusting screws 39; 41 together with the preferably arranged with respect to the axial direction A between them bulge preferably further a straight line, which, however, is oriented obliquely relative to the front clamping gap. By acting forces, for example due to the formed as a spring 107 supporting body 107 and / or the tensioned pressure plate 73, then the at least one front clamping device 21 is preferably pressed together with the clamped pressure plate 73 to the front channel wall 18 that the at least one front Clamping device 21 preferably together with the clamped pressure plate 73 relative to the front channel wall 18 preferably rotates about a substantially radial alignment axis. This alignment axis preferably passes through the first support point 33. This happens in particular because a first axial outer region of the at least one front clamping device 21 and the clamped pressure plate 73 are pulled further to the first channel wall 18, as a second axially outer region of the at least one front clamping device 21 and the tensioned pressure plate 73 located on another axial side of the first support 33rd 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 is thus placed at its front end 74 obliquely on the plate cylinder 07. Such an oblique position of the pressure plate 73 preferably propagates through the entire pressure plate 73 in the circumferential direction D and is further preferably adjusted so that it counteracts an oblique position of the printed image on the pressure plate 73.

If necessary, that is, in particular with a correspondingly deformed print image on the pressure plate 73, the at least two front adjusting screws 39; 41 is set so that a mixture of an inclined position of the pressure 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 in superposition of the effects described above.

An inclination of the pressure plate 73 by means of the at least one front clamping device 21 may also require a compensating inclination and a movement in the axial direction A of the at least one, connected by the at least one rear clamping device 61 to the pressure plate 73 carriage 102 and / or the at least one itself by the flexible mounting 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 axial drive 141 formed as a 141, the at least one rear clamping device 61 and more preferably the at least one carriage 102 in the axial direction A in its position adjustable. A maximum offset of at least a 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 for correcting the plate tension is carried out analogously to the respective seventh process operation, depending on the embodiment of the fixing device 109. However, on the one hand, the first clamping and subsequent unloading of the pressure plate 73 is preferably dispensed with, and on the other hand, depending on the embodiment of the fixing device 109, the at least one rear stop actuator 112 or the at least one rear spacer 131 is set according to the desired new plate tension. If the plate tension has already assumed the ideal value during the trial print in the eighth process operation, the seventh process operation for tensioning the pressure plate 73 is again performed as described above, but using the previously used settings of the at least one rear stop actuating element 112 or the at least one rear spacer 131. An advantage of re-tensioning the pressure plate 73 is, for example, that reproducible conditions prevail and the plate tension can be adjusted uniformly over the entire extent of the pressure plate 73. Therefore, the pressure plate 73 at any setting of 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 tensioned.

After the register has been measured for all printing inks and / or printing plates 73 and compared with a desired printed image, necessary corrections of the printed image are preferably determined and converted into corrections of the settings of the at least one rear clamping device 61. Should a partial image originating from a specific printing plate 73 be too short, it is preferable to calculate a changed setting of the at least one rear spacer 131, which means a greater elongation cause the corresponding pressure plate 73. If a partial image originating from a specific printing plate 73 is too long, an altered setting of the at least one rear spacer 131 is preferably calculated therefrom, which causes a weaker stretching of the corresponding printing plate 73. In one embodiment, these corrections are made at different axially spaced rear spacers 131 of a same plate cylinder 07 independently of each other and in particular different from one another, more preferably based on different correction values determined for different axial positions.

For a correction of a circumferential register error and / or a page register error, a circumferential register adjustment and / or side register adjustment arranged on a cylinder pin 17 of the plate cylinder 07 is preferably used. The pressure plate 73 itself remains unchanged in such settings of the circumferential register and / or the side register clamped on the plate cylinder 07.

Preferably, the method for clamping and / or clamping the printing plate 73 on the plate cylinder 07 is machine-controlled. For this purpose, all drives 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 slide 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 are connected to the machine control and / or by the machine control controlled and / or controllable and more preferably regulated and / or regulated by the machine control. Preferably, the at least one front control element 24 and / or the at least one rear control element 64 are connected to the machine control and / or controlled by the machine control and / or controllable and further preferably controlled and / or controlled by the machine control. In the case of trained as hoses clamping drives 104 and / or actuators 24; 64 and / or Schlittenlöseschläuchen 121 is a control and / or regulation means of the machine control preferably in a control and / or regulation of the pressure prevailing therein by means of the machine control.

A precision of the printing result can be further increased if a profile is created for each plate cylinder 07, which represents deviations of the shape of this plate cylinder 07 of an ideal cylindrical shape and then when each imaging and / or exposure of the pressure plate 73en this respective profile is taken into account , In this way, for example, errors in the printed image can be avoided, which would be caused by a peripheral speed of the pressure plate 73 fluctuates due to the shape of the plate cylinder 07, although an angular velocity of the plate cylinder 07 remains constant. The printing plate 73 can compensate for such regular, geometrically induced fluctuations, for example by at least partially stretched and / or compressed portions of the printed image to be printed.

The method for arranging, in particular for clamping and / or tensioning the pressure plate 73 on the plate cylinder 07 thus preferably comprises at least one front clamping device 21 and in particular the front clamping gap 27 closed in a process operation and thereby the front end 74 of the pressure plate 73rd is clamped in the at least one front clamping device 21 and in particular in the front clamping gap 27 that rotated in a process operation of the plate cylinder about its axis of rotation 11 while the pressure plate 73 is placed on the lateral surface, that in a process operation, the rear end 76 of the pressure plate 73rd placed in the effective range of at least one rear clamping device 61 in its peripheral position on the plate cylinder 07 is that closed in a process operation the at least one rear clamping device 61 and in particular the rear clamping gap 67 while the rear end 76 of the pressure plate 73 in d he at least one rear clamping device 61 and in particular in the rear nip 67 is clamped that in a process operation, the at least one carriage 102 is moved to the at least one front clamping device 21 and the first channel wall 18 to a central or inner position that this central or inner layer as the reference position of the at least one carriage 102 is determined that a trial print is carried out and in particular a register accuracy of the inks of different plate cylinder is compared to each other and thereby a corrected central or inner position of the carriage 102 is determined, then the pressure plate 73 is relieved again, preferably by the at least one carriage 102 again is moved toward the second channel wall 19, more preferably in its peripheral position, that thereafter the at least one slide 102 is again moved towards the at least one front clamping device 21 and the first channel wall 18, up to the corrected central or inner position a targeted th voltage of the printing plate 73 corresponds and that the operations from the execution of the proof, if necessary, be repeated several times until the registration stops satisfactorily.

7. Method according to Claim 1, 2, 3, 4, 5 or 6, characterised in that the at least one tensioning drive (104) is designed as at least one control body (104) that can be acted on and/or is acted on by a pressure means and in that in the first section of the tensioning process and in the third section of the tensioning process at least temporarily a pressure within the control body (104) is in each case greater than in the second section of the tensioning process.
8. Method according to Claim 1, 2, 3, 4, 5, 6 or 7, characterised in that during the entire tensioning process a pressure within a rear release body (64), which can be acted on and/or is acted on with a pressure means, of the least one rear clamping device (61) is equal to an ambient pressure.
9. Method according to Claim 1, 2, 3, 4, 5, 6, 7 or 8, characterised in that in a preceding front clamping process, firstly the at least one front clamping device (21) is closed and at the same time the front end (74) of the printing plate (73) is clamped into the at least one front clamping device (21).
10. Method according to Claim 1, 2, 3, 4, 5, 6, 7, 8 or 9, characterised in that in a rear clamping operation the at least one rear clamping device (61) is closed and at the same time the rear end (76) of the printing plate (73) is clamped into the at least one rear clamping device (61).
11. Method according to Claim 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10, characterised in that in the first section of the tensioning process the at least one slide (102) is moved towards the at least one front clamping device (21) and the first channel wall (18) whereby the printing plate (73) is tensioned with a first force which is just as great as a second force, with which the at least one slide (102) is moved towards the at least one front clamping device (21) and the first channel wall (18) in the third section of the tensioning process whereby the printing plate (73) is tensioned.
12. Method according to Claim 11, characterised in that at the latest after conclusion of the third section of the tensioning process the printing plate (73) is tensioned with a third force that is smaller than the first force and/or the second force.
13. Method according to Claim 11 or 12, characterised in that here a first internal position, in which the at least one slide (102) stops in the first section of the tensioning process, is closer to the first channel wall (18) than a second internal position, in which the at least one slide (102) stops in the third section of the tensioning process.
14. Method according to Claim 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or 13, characterised in that in the tensioning process, firstly, at least one rear stop adjusting element (112) relative to the cylinder barrel (12), supported in a bearing (122) arranged fixed relative to the cylinder barrel (12), is moved into a target stop position and in that then the at least one slide (102) is moved by means of the at least one tensioning drive (104) together with the rear end (76) of the printing plate (73) tensioned in the at least one clamping device (61) towards the at least one front clamping device (21) and the first channel wall (18), until the at least one rear stop adjusting element (112) touches at least one stop body (111) and in that then a fixing device (109) is clamped and the least one slide (102) is held in its position.
