Description

  The present invention relates to a plate cylinder of a printing press as described in the superordinate concept of claim 1.

  In many cases, a printing press supports a plate (printing plate) configured as a mounting type printing plate and uses a plate cylinder configured as a printing plate mounting type plate cylinder. Such plates can be exchanged. For this purpose, an apparatus for fixing the printing plate to the plate cylinder in a detachable manner is necessary. As the demand for accuracy of printed products manufactured by a printing press increases, so does the demand for accuracy of placing the printing plate on the plate cylinder. For example, high-quality printing imposes a requirement that accuracy in the micrometer range is necessary at least at the mutual position of the printing plate. Such accuracy is not achievable with plate clamps of conventional sheet-fed printing presses.

  The problem underlying the present invention is to provide a plate cylinder for a printing press.

  This problem is solved by the configuration described in the characterizing portion of claim 1.

  The advantage obtained by the present invention is that the mounting (placement) of the printing plate on the plate cylinder configured as a printing plate mounting type cylinder can be carried out easily and with high accuracy. In particular, a corresponding device comprising as few movable components as possible is simply constructed. The favorable high reproducibility of the position and orientation of the plate on the plate cylinder is also advantageous. High clamping force also increases the accuracy of the plate position and orientation. This provides a particularly high precision advantage, particularly in a preferred printing press in which a plurality of plate cylinders cooperate with a common rubber cylinder. This is because there is only one place where ink is applied to the substrate, and therefore the accuracy of the printed image is the accuracy of the ink position on the common rubber cylinder, and eventually the printing plate is on the plate cylinder. This is because the accuracy of arrangement and the accuracy of the plate cylinders are dependent only on each other.

However, the power consumed by the adjusting element is exactly the same. This is because, instead, the adjustment distance of at least one adjustment element is doubled. This is because at least one adjusting element arranged between at least two pressing elements can be moved towards both pressing elements, respectively. Thus, if a release tube, in particular an unclamping tube, is used as the adjustment element, it is not necessary for the unclamping tube to be able to achieve a higher pressure than the single pressing element due to the double adjustment force or There is no need to achieve high pressure.

This is because when a plurality of register patterns arranged at different axial positions are compared and a given ink is arranged differently in the axial direction relative to another ink, and an error occurs. If the error is not an error that can be resolved by a common left-right registration device (eg, constant axial movement of the printing plate and / or plate cylinder), this error is based on being able to be corrected by temperature.

The spaced end positions are preferably positions where at least one carriage is spaced from the second groove wall by a predetermined storage section, for example 4 mm to 6 mm. This reserve section is used to increase the potential clamping distance. Here, the concept of a central position is for distinguishing between end positions and / or spaced end positions, and in particular means that the position need not be exactly centered. Preferably, in the rear insertion process, the rear end of the printing plate previously placed around the plate cylinder has the second groove wall and the plate in the circumferential direction with the rear end being at least a predetermined portion.

  Preferably, in the clamping process, the at least one carriage is moved along the clamping path towards the at least one forward clamping device and the first groove wall, whereby the plate is clamped. Preferably, in the first step of the clamping process, the at least one carriage is moved along the clamping path towards the at least one forward clamping device and the first groove wall. In that case, the printing plate is preferably clamped with a first force. In this case, the printing plate is preferably tightened more strongly than set for the printing operation using this printing plate. Preferably, in the second step of the clamping process, the plate is again relaxed by moving the at least one carriage again towards the second groove wall. Preferably, in the third step of the clamping process, a new at least one carriage is moved towards the at least one forward clamping device and the first groove wall. In this case, the printing plate is preferably clamped with the second force. Preferably, the first force is exactly the same as the second force. Preferably, the printing plate is clamped or clamped on the rear clamping device from the start of the first step of the clamping process to the end of the third step of the clamping process. Depending on the configuration of the at least one rear clamping device that is preferably used, one of both forms described below of the clamping process is preferably used.

  In the first form of the clamping process, in particular the third step of the clamping process, preferably at least one carriage is first clamped into at least one rear clamping device of the printing plate by at least one clamping drive. With at least one rear clamping end, which is moved towards at least one front clamping device and the first groove wall, after which it is preferably part of at least one carriage, preferably at least one rear The spacer is adjusted to a predetermined position relative to the at least one carriage, the predetermined position being independent of the at least one clamping drive and at least one rearward from the second groove wall.

  An advantage of this plate cylinder and of this method is, for example, that the clamping drive can also preferably be used to move the rear clamping device to the following position. In this position, the rear end of the printing plate can be easily mounted, and can be made in a substantially radial direction without manually inserting the printing plate into the rear clamping device. This is because the rear clamping device is preferably moved so as to surround the rear edge of the plate. Moreover, in this case, the radially outer clamping element is stationary relative to the carriage, so that a particularly stable clamping can be achieved.

  An advantage of a preferred form of the plate cylinder and / or method is that, for example, the clamping device or the drive of the clamping device does not have to be operated while the printing plate is clamped and / or clamped.

A minimal reduction of the clamping force to the force is made, in which case the printing plate remains initially clamped for trial printing. When it becomes clear that a change is to be made, the printing plate is first at least partially, preferably fully relaxed, and then subjected to a modified extension of the printing plate and the printed image by at least one carriage. The newly determined third clamping force to be generated is applied. Subsequently, a minimum reduction of the clamping force to the fourth clamping force is performed, and a printing operation is preferably performed at that time. Preferably, the difference between the first clamping force and the second clamping force is much smaller than the difference between the first clamping force and the third clamping force.

The staff is to be protected. When using a clamping drive, in particular, a very high force is generated, since a high force is exerted on the corresponding device for clamping and / or aligning the printing plate. If, for example, the carriage is in a position where there is a gap between the carriage and the groove wall, for example at the same time the printing plate is not yet arranged on the plate cylinder or the printing plate is no longer arranged on the plate cylinder. Therefore, the operator's finger can access the gap. In the event of a failure of the drive device that moves the carriage to this position and holds it, the carriage moves towards the groove wall, possibly with a large force and / or speed, creating a danger in this gap. This risk arises due to the large adjustment distance and / or movement of the carriage, especially in the absence of a clamped printing plate.

  A first embodiment of the fixing device 109 will be described below. In a first embodiment, the fixing device 109 has at least one preferably adjustable rear adjustment element 131, particularly preferably an adjustable rear spacer 131. This spacer 131 is preferably configured as at least one rear adjustment screw 131. The at least one rear spacer 131 is preferably connected to the at least one carriage 102 and the at least one rear clamping device 61 via a support, preferably having at least one thread or configured as a thread. In particular, it is supported by the rear base body 71. Further, the at least one rear spacer 131 can be supported by a support portion provided on a constituent part of the cylinder 12 or a constituent part arranged so as not to move relative to the cylinder 12. The at least one rear spacer 131 is movable relative to the at least one carriage 102 and is adjustable in particular relative to the at least one carriage 102, for example by screw movement in at least one thread. is there. At least one rear spacer 131 is preferably movable with at least one carriage 102. The at least one rear spacer 131 can be arranged in at least one shortened position and in at least one, preferably a plurality of extended positions, in particular relative to the at least one carriage 102. In at least one extended position of the at least one rear spacer 131, the at least one rear spacer 131 is preferably further in the direction toward the second groove wall 19 than in the shortened position. The carriage 102 protrudes from the rear end surface 132 near the second groove wall 19.

  When at least one rear spacer 131 is supported by a support part provided on a component part of the trunk 12 or a component arranged relatively stationary with respect to the cylinder 12 via the support part. The at least one rear spacer 131 can be arranged in at least one shortened position and in at least one, preferably a plurality of extended positions, in particular relative to the barrel 12. In at least one extended position of the at least one rear spacer 131, the at least one rear spacer 131 is preferably further in the direction toward the at least one carriage 102 than in the shortened position. It protrudes from the second groove wall 19 closer to 102.

  As described above, the at least one return adjustment element 106 causes a return adjustment force applied to the at least one carriage 102 oriented in a direction opposite to the clamping direction E. In other words, at least one carriage 102 is pressed against the second groove wall 19 unless an opposing force acts. However, depending on the position of the at least one rear spacer 131, the at least one carriage 102 is prevented from reaching the second groove wall 19 as much as possible and in particular reaching the end position of the carriage 102. If at least one rear spacer 131 is in a shortened position and at least one rear spacer 131 and / or at least one carriage 102 itself is in contact with the second groove wall 19, then at least one carriage 102 is arranged further away from at least one front clamping device 21 than when at least one rear spacer 131 is in a predetermined extended position and is in contact with the second groove wall 19. Yes. The minimum distance between the at least one front clamping gap 27 and the at least one rear clamping gap 67 is also corresponding. That is, a plate 73 clamped by at least one front clamping device 21 and at least one rear clamping device 61 and placed around the cylinder 12 is at least one when the clamping drive 104 is inactive. Depending on the position of the rear spacer 131, it is tightened to some extent.

It is operated so that 73 is first tightened. In this embodiment, the at least one rear spacer 131 is first arranged in a shortened position relative to the at least one carriage 102. At least one carriage 102 and thus the entire at least one rear clamping device 61 moves towards at least one front clamping device 21. Thereby, the printing plate 73 wound around the plate cylinder 07 is tightened, that is, tightened, tensioned or tensioned. The at least one carriage 102 preferably moves to such an extent that the desired tension of the plate 73 is obtained or more preferably at least slightly exceeded. Subsequently, the at least one rear spacer 131 is moved from the shortened position to a predetermined extended position.

For this reason, it is not necessary to keep the drive operating continuously, in particular it is not necessary to keep the tube continuously supplied with pressure. At least one clamping drive 104, at least one rear spacer 131 and at least one rear adjustment element 64 are preferably supported on the same component of the carriage 102 and at least one rear clamping device 62.

  The exact position of the at least one rear spacer 131 determines the minimum distance of the at least one carriage 102 from the second groove wall 19. Therefore, the maximum clamping force acting on the clamped printing plate 73 is determined by the exact position of the at least one rear spacer 131. Preferably a plurality, more preferably at least four of the aforementioned rear spacers 131 are spaced apart from one another in the axial direction A.

The at least one carriage clamp element 114 is preferably arranged to be movable relative to the at least one carriage 102 by at least one drive device 116 configured as a carriage release drive device 116. The at least one carriage release drive 116 causes the at least one carriage clamp element 114 to be brought into contact with and / or out of contact with the first carriage clamp surface 117 of the at least one groove 13. In the fixed position of the at least one carriage 102, the at least one carriage release drive 116 is supported on the one hand by at least one carriage 102 and thus by at least one rear clamping device 61 and on the other hand at least by one. One carriage release driving device 116 is supported on the first carriage clamp surface 117 of the groove 13 via at least one carriage clamp element 114.

However, preferably, at least two carriage pressing elements 119 are always under some degree of preload, so another, for example the third extending direction, draws a slight arc and each carriage pressing element 119 is slightly curved. This is preferably true regardless of the state of the carriage release tube 121, especially for at least two carriage pressing elements 119, especially when the carriage release tube 121 is completely empty. This is because the size of the mounting space is set so that there is not enough room for relaxation. At least one carriage release tube 121 is arranged between at least two carriage pressing elements 119 and preferably also extends in the axial direction A. At least two carriage pressing elements 119 are movable, in particular pivotable, by at least two coupling elements, to each other and / or to the base body 71 of at least one rear clamping device 71 and / or to at least one carriage clamping element 114. Are combined. At least one carriage release tube 121 is arranged between at least two coupling elements, at least preferably in the axial direction A.

The at least two carriage pressing elements 119 are preferably movably, more preferably pivotably attached to the carriage clamp element 114, more preferably by at least one of the at least two coupling elements. ing. At least one clamping element is disposed on each side of the carriage release tube 121 so as to prevent the ends of at least two carriage pressing elements 119 from exceeding the maximum separation distance. The arrangement of the clamping elements is such that the ends of the clamping elements cannot be separated from the ends of the adjacent carriage pressing elements 119, so that when the carriage release tube 121 expands, at least two carriage pressing elements 119 are arranged. Does not just pivot away from each other, but causes it to curve outward in the direction away from the tube. Preferably, the at least one clamping element is formed by at least one carriage clamp element 114. Preferably, the at least one clamping element is formed by a base body 71 of at least one rear clamping device 61.

  However, due to the formation of the curvature, the at least two carriage pressing elements 119 shorten, for example, in the direction from one coupling element through the carriage release tube 121 toward the other coupling element. In particular, the linear spacing between the two ends of the same carriage pressing element 119 is shortened. Thereby, the at least one carriage clamping element 114 moves relative to the base body 71 of the at least one rear clamping device 61, in particular towards the base body 71, and the clamping is released. For example, the at least two coupling elements are configured as coupling pins, the coupling pins passing through the slots of the at least two carriage pressing elements 119 and at each end at the base of at least one rear clamping device 61. Coupled to the body 71 or to at least one carriage clamp element 114.

An example of such deactivation of the at least one forward carriage release member 121 is a pressure drop inside the carriage release tube 121, for example to ambient pressure, in particular to atmospheric pressure.

In this embodiment, the fixing device 109 is such that, for example, the carriage release tube 121 is pressurized with a predetermined pressure, whereby both carriage spring sets 119 are deformed and at least one carriage clamp element 114 is pulled back. This is canceled. At least one carriage 102 and thus the entire at least one rear clamping device 61 moves towards at least one front clamping device 21. Thereby, the printing plate 73 wound around the plate cylinder 07 is tightened. The at least one carriage 102 preferably moves until an equilibrium is established between the force applied by the at least one clamping drive 104 and the force opposite this force. This equilibrium is established when a predetermined pressure is applied to the inside of the tightening tube 104. In this case, preferably, the at least one rear stopper adjusting element 112 contacts the at least one stopper body 11 at the stopper contact portion 123 toward the at least one carriage 102.

It is pinched by. As soon as the fixing device 109 is clamped, the clamping drive 104 is deactivated, for example by reducing the pressure in the clamping tube 104 to, for example, ambient pressure, in particular atmospheric pressure.

For this purpose, preferably at least one rear adjustment screw 131 is rotated about its thread axis relative to at least one carriage 102 and / or relative to the barrel 12. More preferably, at least one drive 134 configured as a spacer drive 134 is more preferably rotated until at least one rear spacer 131 contacts the second groove wall 19. . Subsequently, the printing plate 73 is reduced in clamping force, for example, preferably by moving at least one carriage 102 at least minimally and again towards the second groove wall 19, preferably by at least one rear spacer. 131 is again partially relaxed by contacting the second groove wall 19 at at least one spacer contact point 133, preferably fully supported there. For this purpose, at least one clamping drive 104 is preferably at least partially deactivated. More preferably, the pressure in the at least one clamping tube 104 is reduced, in particular the at least one clamping tube 104 is reduced to a lower pressure than before, for example to ambient pressure, in particular under atmospheric pressure. The plate 73 is now tightened and the plate cylinder 07 is in the eighth operating state in the first embodiment. In particular, in the first step of the tightening process and the third step of the tightening process, at least temporarily, the pressure in the tightening tube 104 is higher than the second step of the tightening process, respectively. Preferably, the third force for clamping the printing plate 73 in the eighth operating state is the first force and / or for clamping the printing plate 73 during the first step and / or the second step of the clamping process. Is at least less than the second force.

  The eighth operation state of the first embodiment, which is also referred to as a tightening state or a printing operation state, is preferably at least 1 when the fixing device 109 according to the first embodiment is used. One carriage 102 has a greater spacing from the second groove wall 19 than in the seventh state, and at least one carriage 102 has a smaller spacing from the first groove wall 18 than in the seventh operating state. The position of the at least one rear spacer 131 is changed relative to the at least one carriage 102, and the at least one rear spacer 131 is relative to the at least one carriage 102 in the circumferential direction D. Relatively to the second groove wall 19 rather than in the seventh operation state, the printing plate 73 is clamped on the peripheral surface 124 of the plate cylinder 07. It is different in that there only. In this eighth operating state, the plate cylinder 07 is ready for a printing operation and / or the printing cylinder is in a printing operation.

  On the other hand, regarding the fixing device 109 according to the second embodiment, the seventh method process, which is also referred to as a tightening process, is preferably performed as described below. First, in the first step of the clamping process, preferably at least one carriage 102 is moved towards at least one forward clamping device 21 and first groove wall 18, more preferably in a printing operation. The printing plate 73 is prepared by being moved more than set for the printing. In this case, in particular, the at least one carriage 102 is moved away from the second groove wall 19. For this purpose, the fixing device 109 is first released by actuating at least one drive device 116, which is configured as a carriage release drive device 116. For this purpose, for example, the pressure in the carriage release tube 121 is increased and the carriage spring set 119 is deformed, whereby the at least one carriage clamp element 114 is released from the first carriage clamp surface 117. Preferably, at least one stopper body 111 is moved to the passing position, thereby facilitating the later movement of at least one carriage 102 by at least one drive device, more preferably configured as a positioning drive device. Can be. Thereupon, at least one tightening drive 104 is activated. More preferably, the at least one clamping drive 104 is pressurized with compressed air, preferably under a pressure of 3 bar to 10 bar, more preferably 6 bar to 8 bar. The at least one clamping tube 104 is supported by both the second groove wall 19 and at least one carriage 102, so that at least one carriage 102 is moved. This pressure is preferably selected to be higher than that set in the rear insertion process because it is necessary to work against the tension formed on the plate 73.

  Subsequently, in the second step of the clamping process, the plate 73 is moved by moving the at least one carriage 102 again toward the second groove wall 19 and, more preferably, at its end position. Relaxed again. For this purpose, at least one clamping drive 104 is deactivated. More preferably, the pressure in the at least one clamping tube 104 is reduced, in particular the at least one forward clamping tube 104 is reduced to a lower pressure, for example ambient pressure, in particular atmospheric pressure. Then, preferably, at least one rear stopper adjustment element 112 is first moved relative to the barrel 12 with respect to the clamping direction E, more preferably to the stopper target position. It is moved by at least one drive device configured as a drive device.

  Therefore, preferably, in the third step of the clamping process, at least one carriage 102 is newly moved towards at least one front clamping device 21 and the first groove wall 18, in particular the second groove. It is moved away from the wall 19 until a desired clamping force is obtained. For this purpose, at least one clamping drive 104 is again activated. More preferably, the at least one clamping tube 104 is preferably 2 bar to 8 bar, more preferably a printing plate 73 with a support plate made of aluminum, and a plate with a support plate made of steel, 2 bar to 5 bar. The plate 73 is pressurized with compressed air under a pressure of 3 to 7 bar. Before and / or after and / or simultaneously, at least one stopper body 111 is moved to the stopper position, more preferably by means of a drive device configured as at least one positioning drive device, preferably at least One rear stopper adjustment element 112 is moved until it contacts at least one stopper body 111.

  For this purpose, more preferably, at least one rear stop screw 112 is rotated about its screw axis. As a result, as described above, the maximum adjustment distance of at least one carriage 102 and, consequently, the maximum clamping force acting on the clamped printing plate 73 are determined. The continuation of the movement of the at least one carriage 102 is in this case impossible due to the contact between the at least one rear stopper element 112 and the at least one stopper body 111.

  Subsequently, the fixing device 109 is clamped, in which case, for example, the pressure in the carriage release tube 121 causes the carriage spring set 119 to relax so that at least one carriage clamp element 114 is brought into contact with the first carriage clamp surface 117. To the extent that it is pressed, for example, it is reduced to ambient pressure, in particular to atmospheric pressure. As soon as the fixing device 109 is clamped, the clamping drive 104 is deactivated, for example by reducing the pressure in the clamping tube 104 to eg ambient pressure, in particular atmospheric pressure. In this state, the rear clamping device 61 fixes the at least one carriage 102 and thus the at least one rear clamping device 61 at a predetermined position in the at least one groove 13. In that position. At this time, the printing plate 73 is tightened, and the plate cylinder 07 is in the eighth operating state in the second embodiment.

  The eighth operation state in the second embodiment, which is also referred to as the tightening state or the printing operation state, is preferably at least the seventh operation state when using the fixing device 109 in the second embodiment. One carriage 102 has a greater spacing from the first groove wall 19 than in the seventh operating state, and at least one carriage 102 has a smaller spacing from the first groove wall 18 than in the seventh operating state. The only difference is that at least one stopper body 111 contacts at least one rear stopper adjusting element 112 and the plate 73 is clamped on the peripheral 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 printing cylinder is in a printing operation.

  Regardless of the embodiment of the clamping process, the plate 73, in particular its rear end 76, is preferably clamped at the rear from at least the start of the first step of the clamping process to the end of the third step of the clamping process. It remains clamped to the device 61. Regardless of the embodiment of the tightening process, preferably in the first step of the tightening process, the at least one carriage 102 has at least one forward clamping device 21 and the first groove wall 18 by a first force. The plate 73 is clamped at this time. The first force is preferably moved in the third step of the clamping process by moving the at least one carriage 102 towards the at least one forward clamping device 21 and the first groove wall 18 to form the printing plate 73. Is the same magnitude as the second force for tightening. Preferably, in this case, the first central position or the first inner position where the at least one carriage 102 stops in the first step of the clamping process is the third step of the clamping process of the at least one carriage 102. The second groove wall 19 is closer to the second central position than the second central position or the second inner position. This is based on the fact that the printing plate 73 descends in the first step of the clamping process, at which time the tension is relieved and any gaps present are reduced, ie the printing plate 73 is adjusted overall. ing.

  Preferably, regardless of the embodiment of the fixing device 109, at least one trial printing is performed in at least one eighth method step. Printing for the trial printing is performed on a sample of a printed product, for example, a sheet 09. Based on the formed printed image, whether and how much the plate tension should be changed and / or whether or not the inclination position of the plate 73 on the plate cylinder 07 should be changed and how much Whether and / or to what degree the convex and / or concave deformation of the front end 74 of the plate 73 and / or the rear end 76 of the plate 73 should be changed Evaluated on whether to change. If the printed image is already satisfactory, all adjustments of the clamping device 101 are maintained. This process is preferably repeated as many times as necessary. More preferably, in order to determine the complete and final adjustment of the plate cylinder 07, more preferably the complete and final adjustment of all the plate cylinders 07 working with one common rubber cylinder 06, it is no longer necessary. This process does not require trial printing.

  If necessary, in at least one ninth method step, an adaptation adjustment of the clamping device 101 is preferably performed in response to the evaluation in the eighth method step. The ninth method process is also called the adaptation process. Regardless of the shape of the fit, preferably the fixing device 109 is first released again and the printing plate 73 is at least partially relaxed.

  When the first embodiment of the fixing device 109 is used, in the ninth method process or adaptation process, the at least one carriage 102 is first moved away from the second groove wall 19 again and the first groove wall 18. And moved toward the at least one forward clamping device 21. For this purpose, at least one clamping drive 104 is preferably activated. More preferably, the pressure medium can be pressurized and / or pressurized until at least one carriage 102 performs the aforementioned movement towards the first groove wall 18 and / or at least one forward clamping device 21. The at least one regulating body 104, in particular at least one clamping tube 104, is pressurized with a pressure medium, compressed air, preferably under a pressure of 3 bar to 10 bar. The at least one carriage 102 is then stopped, for example by contact with at least one stopper and / or force balance between at least one adjustment body 104 and at least one return adjustment element 106. Thus, at least one rear spacer 131 from the second groove wall 19 is at least one rear spacer 131 relative to the at least one carriage 102 and / or relative to the barrel 12. Adjusted to a position that allows for a smaller spacing. For this purpose, preferably at least one rear adjustment screw 131 is rotated about its thread axis relative to at least one carriage 102 and / or relative to the barrel 12. More preferably, it is rotated by at least one spacer drive 134. Preferably, at least one spacer drive 134 is controlled by a machine controller. Subsequently, at least one carriage 102 is moved again towards the second groove wall 19 away from the first groove wall 18 and / or at least one front clamping device 21, preferably at least 1 One carriage 102 is again at its end position and / or at least one rear spacer 131 is moved at least one spacer contact point 133 until it contacts the second groove wall 19 and at least one carriage 102 at the same time. As a result, the printing plate 73 is relaxed again. For this purpose, at least one clamping drive 104 is preferably at least partially deactivated. More preferably, the pressure in the at least one adjustment body 104, in particular the clamping tube 104, pressurized with a pressure medium is reduced, in particular the at least one adjustment body 104, in particular the clamping tube 104, has a lower pressure than before, For example, it is reduced to ambient pressure, in particular to atmospheric pressure.

  In use of the second embodiment of the fixing device 109, in the ninth method step, preferably at least one clamping drive 104 is first activated. More preferably, at least one clamping tube 104 is pressurized with compressed air, preferably under a pressure of 3 bar to 10 bar. At least one carriage 102, in particular at least one rear stop adjusting element 112, is then pressed against at least one stop body 111 with a sufficiently large force by at least one clamping drive 104. Next, the fixing device 109 is preferably released first, for example in this case the pressure in the carriage release tube 121 causes the carriage spring set 119 to be deformed, whereby the at least one carriage clamp element 114 is moved to the first carriage clamp. It is raised to the extent that it is released from the surface 117. Subsequently, the printing plate 73 is relaxed again, in which case at least one carriage 102 is again moved towards the second groove wall 19 and preferably at least one carriage 102 is again located at its end position. And / or at least one rear spacer 131 is moved until it contacts the second groove wall 19 at at least one spacer contact point 133. For this purpose, at least one first clamping drive 104 is preferably at least partially deactivated. More preferably, the pressure in the at least one clamping tube 104 is reduced, in particular the at least one clamping tube 104 is reduced to a lower pressure than before, for example to ambient pressure, in particular under atmospheric pressure.

  Then, regardless of the embodiment of the fixation device 109, one or more of the following partial processes are performed as one or more parts of the adaptation process.

  In a partial process of the fitting process for correcting the inclined position of the printing plate 73 and / or in a partial process of the fitting process for correcting the convex and / or concave deformation of the front end 74 of the printing plate 73, At least one of the at least two support points 34; 36, preferably at least two second support points 34; 36, are newly adjusted if necessary. To this end, preferably at least one front clamping device 21, in particular at least one radial direction, in the front contact body 39; 41 configured as at least two, preferably front adjustment screws 39; 41. The position relative to the outer front clamping element 22 and / or the trunk 12 is adjusted. More preferably, the at least two forward contact bodies 39; 41 are repositioned by at least one drive 43; 44 configured as a front auxiliary drive 43; 44. More preferably, at least one, in particular at least two front adjustment screws 39; 41, relative to the at least one front clamping device 21 and / or in the barrel 12 about its thread axis. Relative to the rotation. Preferably, at all times at all support points 33; 34; 36, the first groove wall 18 and at least one front clamping device 21, in particular at least one radially outer front clamping element 22, Particularly with respect to the first groove wall 18 by adjustment of the at least two second support points 33; 34, since they are in contact with each other in the form of protrusions and at least two forward contact bodies 39; The preferred at least one forward clamping device 21 is influenced by the elastic bending and / or tilting position. As a result, it is possible to correct a corresponding position defect of a print image originating from a specific printing plate 73 relative to the position of at least one printing image originating from at least one other printing plate 73.

  For example, the direction in which the at least two front contact bodies 39; 31, in particular the adjusting screw 39; 41, move away from the first groove wall 18 relative to the projection of the at least one front clamping device 21 during the adjustment. The ends of the at least two forward contact bodies 39; 41, in particular the adjusting screws 39; 41, close to the first groove wall 18, are preferably arranged between them in the axial direction A. With the protrusion, for example, it does not form a straight line and / or forms a separate line from the previous curved line. At least one front clamping device 21 is clamped with at least one front clamping device 21 by means of a force acting on the support body 107 configured as a spring 107 and / or a clamped printing plate 73, for example. The axially outer area of the printing plate 73 is moved toward the first groove wall 18 more strongly than the axially central area of at least one front first clamping device 21 and the clamped printing plate 73. And / or preferably elastically deformed, for example to be pulled. That is, the clamped printing plate 73 is deformed into a convex shape at the front end 74 thereof. Such a convex deformation at the front end 74 of the printing plate 73 may propagate at least partially in the circumferential direction D throughout the printing plate 73. The deformation of the convex surface at the front end 74 of the printing plate 73 is preferably adjusted to counteract the concave deformation of the printed image on the printing plate 73. In some cases, it is necessary to take corresponding measures on the rear end 76 of the printing plate 73, for example, to adjust the at least one rear adjustment element 131 with corresponding changes.

  For example, at least two front contact bodies 39; 41, in particular an adjustment screw 39; 41, when adjusting, are directed towards the first groove wall 18 relative to the projection of the at least one front clamping device 21. When moved, the ends of the at least two forward contact bodies 39; 41, in particular the adjusting screws 39; 41, close to the first groove wall 18, preferably with respect to the axial direction A, project between them. With the part, for example, it does not form a straight line and / or forms a separate line from the previous curved line. At least one front clamping device 21 is clamped with at least one front clamping device 21 by means of a force acting on the support body 107 configured as a spring 107 and / or a clamped printing plate 73, for example. The axially outer region of the printing plate 73 is moved toward the first groove wall 18 with a slightly lower strength than the at least one front clamping device 21 and the axially central region of the clamped printing plate 73. Is preferably elastically deformed, such as being pulled and / or pulled. That is, the tightened printing plate 73 is deformed into a concave shape at the front end 74 thereof. Such a concave deformation at the front end 74 of the printing plate 73 can propagate at least partially in the circumferential direction D throughout the printing plate 73. The concave deformation at the front end 74 of the printing plate 73 is preferably adjusted to counter the convex deformation of the printed image on the printing plate 73. Again, in some cases, it is necessary to take corresponding measures on the rear end 76 of the plate 73, for example to adjust the at least one rear adjustment element 131 with corresponding changes.

  For example, if at least two front contact bodies 39; 41, in particular the adjusting screw 39; 41, are moved relative to each other relative to the protrusion of the at least one front clamping device 21 during the adjustment, The end of the at least two forward contact bodies 39; 41, in particular the adjusting screw 39; 41, close to the first groove wall 18, preferably with respect to the axial direction A, with a protrusion arranged therebetween Continues to form a straight line or a curved line of exactly the same strength as before, but this line is oriented obliquely with respect to the front clamping gap 27 and / or the first groove wall 18. . Due to the force acting on the support body 107 and / or the clamped printing plate 73, for example configured as a spring 107, the at least one front clamping device 21 is preferably at least one with the clamped printing plate 73. The two front clamping devices 21 are preferably rotated relative to the first groove wall 18 together with the clamped printing plate 73, preferably about a substantially radial direction adjustment axis. 1 is pressed against the groove wall 18. This directional axis preferably extends through the first support location 33. This is particularly the case when the first zone on the axially outer side of the at least one front clamping device 21 and the clamped printing plate 73 is the first of the at least one front clamping device 21 and the clamped printing plate 73. The reason is that the support portion 33 is pulled toward the first groove wall 18 further than the second region outside in the axial direction, which is located on the axial direction side different from the first region outside in the axial direction. Done in For example, the axially outer first region corresponds to side I, and the axially outer second region corresponds to side II. That is, the front end 74 of the tightened printing plate 73 is attached to the plate cylinder 07 obliquely. Such an inclined position of the plate 73 is preferably propagated in the circumferential direction D throughout the printing plate 73, and more preferably, such an inclined position is opposed to the inclined position of the printed image on the printing plate 73. Adjusted to do.

  If necessary, in particular if the printed image on the plate 73 is deformed accordingly, the at least two front adjustment screws 39; 41 overlap the above-mentioned effects while on the plate cylinder 07. The position is adjusted so that a combination of the inclined position of the printing plate 73 and, on the other hand, the convex and / or concave deformation of the printing plate 73 itself occurs.

  The inclined position of the printing plate 73 by the at least one front clamping device 21 is optionally at the same time at least one carriage 102 coupled to the printing plate 73 by at least one rear clamping device 61 and / or at least one rear It is necessary to move in the inclined position and / or the axial direction A for correcting the clamping device 61 itself. Flexible support and / or fixing of at least one carriage 102 and / or at least one rear clamping device 61 on the one hand and at least one side adjustment device 144, in particular an axial drive device on the other hand. By means of the drive device 141, the position of at least one rear clamping device 61, more preferably at least one carriage 102, can be adjusted in the axial direction A. The maximum displacement of the at least one carriage 102 and the at least one rear clamping device 61 in the axial direction A, in particular from the end position to the end position, is preferably 1 mm to 10 mm, more preferably 3 mm to 6 mm. .

  Part of the adaptation process for correcting the plate tension on the one hand and hence the length of the plate 73 in the circumferential direction, and on the other hand for correcting the convex and / or concave deformations of the rear end 76 of the plate 73. The process is preferably performed in the same way as the seventh method process, depending on the embodiment of the fixing device 109. However, in this case, preferably, on the one hand, the first clamping of the printing plate 73 and subsequent relaxation is not necessary, and on the other hand, at least one rear stop adjustment element 112, depending on the embodiment of the fixing device 109. Alternatively, the at least one rear spacer 131 is adjusted according to the desired new plate tension. If the adjustment of the at least one rear stop adjustment element 112 or the at least one spacer 131 has already taken up an ideal value in the trial printing in the eighth method step, preferably as described above A seventh method step for tightening 73 is newly performed, but using the previously used adjustment of at least one rear stop adjustment element 112 or at least one rear spacer 131. The advantage of the new clamping of the printing plate 73 is that, for example, a reproducible situation occurs and the printing plate tension can be adjusted uniformly over the entire stretched length of the printing plate 73. Therefore, the plate 73 is completely retightened during the adjustment of each of the at least two front adjustment screws 39; 41 and / or at least one rear stopper adjustment element 112 or at least one rear spacer 131.

  After all the ink and / or printing plate 73 registers (register marks, register marks) are measured and compared with the target printed image, the required correction of the printed image is preferably determined in the inspection and evaluation processes. , Converted into an adjustment correction of the at least one rear clamping device 61. If the partial image originating from a particular printing plate 73 is too short, this preferably determines and preferably calculates a modified adjustment of at least one rear spacer 131. This adjustment results in a correspondingly strong extension of the printing plate 73. If the partial image originating from a particular printing plate 73 is too long, this preferably determines and preferably calculates a modified adjustment of at least one rear spacer 131. This adjustment results in a weak extension of the corresponding printing plate 73. In one embodiment, these corrections are performed separately and independently from each other in different rear spacers 131 of the same plate cylinder 07 which are spaced apart from one another in the axial direction. More preferably, it is performed based on various correction values obtained for different axial positions.

  In the following, the inspection process, the evaluation process and / or the adaptation process will be described in detail. Through these processes, for example, a registration failure can be grasped and corrected particularly quickly and reliably.
