Definitions
- the invention relates to an elevator of a forme cylinder of a rotary printing press according to the preamble of claim 1.
- DE 28 03 908 A1 discloses a device for fastening a rubber blanket on a cylinder of a rotary printing press for offset printing, with a printing blanket having a plurality of layers being integrally connected on its side facing the cylinder to a thin metal plate which is fastened with a magnetic one Cylinder works together.
- the layers of the printing blanket arranged cohesively on the metal plate include, among other things, a compressible layer. Between the metal plate and the cylinder, the blanket can be used for correction purposes with intermediate layers - usually in offset printing. Plastic films to correct the overall thickness - to be relined. Such layer structures and intermediate layers differ significantly from those for printing plates in high pressure or flexographic printing.
- the US 46 28 815 A shows a device for fastening a printing plate for flexographic printing, the metallic plate being padded by an elastic layer in the printable area and being held magnetically on the cylinder in the non-padded area.
- DE 38 32 515 A1 discloses the attachment of a pressure plate with an elastic base, the base having magnetic powder for the purpose of attachment to a cylinder surface.
- the US 36 70 646 A shows a printing form for flexographic printing, the printing form on a saddle fixed to the cylinder is arranged.
- the saddle In the area of the printing form ends, the saddle has permanent magnets in the circumferential direction, by means of which the ends of the printing form are held on the saddle.
- a pressure plate has a magnetizable base plate and a rubber layer on the base plate.
- the pressure plate can be attached to a magnetic cylinder by means of magnetic force.
- a forme cylinder disclosed in DE 34 14 533 A1 has a base with elastic properties between the printing form and its outer surface.
- the printing form is attached, for example, by means of adhesive films to prevent undesired changes in location, and can also be securely positioned using register aids.
- the invention has for its object to provide an elevator of a forme cylinder of a rotary printing press.
- an elastic substructure between the printing form and the jacket of the cylinder is advantageous when fastening an elevator on forme cylinders of rotary printing presses, in particular a printing form of a form cylinder for a high-pressure or flexographic printing unit.
- This elastic substructure compensates for tolerances in the thickness of the printing form and in the concentricity of the cylinder.
- such a substructure should advantageously be arranged under the printing form, usually a polymer plate. This also applies in particular when there is increased wear on the printing form, for example when using special ones aggressive colors should be avoided. This is, for example, with increased hardness for the printing form - e.g. B. about 70 Shore - achieved in connection with the structure according to the invention.
- a reversibly deformable, elastic substructure is particularly advantageous in order to ensure that the somewhat harder printing form is evenly applied with ink.
- the advantages that can be achieved with the invention consist in particular in that, by executing the elevator in several layers, consisting of an inner layer of elastic material and an outer layer that supports the printing form with its raised relief, simplified manufacture of the elevator, quality improvements due to less deformation and less fluctuation in tolerance as well as an at least partial recyclability can be achieved.
- An essential of the advantages mentioned is that production is simplified, in particular for printing forms with a raised relief.
- a two-stage production of the printing form whereby, for example, a metal plate is first pre-bent for processing and then an elastic substructure is glued on, is not necessary since the thickness of the split version is smaller than that of a firmly connected, multi-layer printing form, a so-called sandwich plate.
- the risk of collapse, such as exists when a sandwich panel with an elastic substructure that has just been rolled off is advantageously not present. As a result, it is possible to produce the printing form evenly, and thus significantly more cost-effectively.
- the two layers When assembling the elevator, the two layers can be hung in the area of one end in a register device for the printing form, and then both can be drawn onto the outer surface. This prevents wrinkles and allows the resulting bumps to lie one on top of the other.
- Another advantage of the design of the multi-layer elevator is that the elastic substructure which is not firmly connected to the printing form, for example a polymer plate arranged on a sheet, remains usable, while, for example, only the printing form containing the relief is replaced.
- the only drawing shows a schematic representation for the attachment of a multi-layer elevator to a forme cylinder.
- a forme cylinder 01 is arranged, which has at least magnetic areas on its outer surface 02.
- the magnetic field can be generated by permanent magnets or by electromagnets.
- magnets, in particular permanent magnets, of high magnetic force is advantageous.

- the substructure 04 is located on the outer surface 02 between the outer surface 02 and the outer surface 04 Printing form 06.
- the substructure 04 consists of a reversibly deformable and / or elastic, in an advantageous embodiment compressible material or at least, in the case of a multilayer structure, has an elastic, compressible layer.
- the substructure 04 is single-layer, compressible and closed-pore. By using closed-pore materials for the compressible layer of the substructure 04, a second layer to protect the pores against moisture, color and dirt is not necessary.
- a multi-layer structure of the substructure 04 is also suitable, wherein, particularly when using open-pore materials as a compressible layer, the open pores are covered by a second layer, not shown is provided.
- open-pore cell structures such as. B. polyurethane elastomers
- a cover against moisture penetration of the open-cell surface by a plastic such as a film made of polyester. This cover can be provided on both sides of the compressible layer, preferably integrally connected to it.
- the printing form 06 for example a printing form 06 for high or low pressure, has a multilayer structure and has a first layer 07 facing the substructure 04 and a second layer 08 which is connected to the first layer 07 in a form-fitting or material-locking manner.
- the first layer 07 of the outer layer 06 has, at least in some areas, on its side 09 facing the outer surface 02 of the cylinder 01, a magnetically attractable material, preferably containing a ferromagnetic material.
- the first layer 07 is designed as a metal sheet 07, which is attracted to the lateral surface 02 of the cylinder 01 by the magnetic force.
- the second layer 08 On a side 11 of the plate 07 facing away from the lateral surface 02 of the cylinder 01, the second layer 08, which cooperates with a second cylinder or a printing material during the printing process, is arranged.
- the layer 08 is designed as a polymer plate 08 for high-pressure or flexographic printing, and on its side facing away from the plate 07 it has a printing relief 12 projecting out of the layer 08.
- One or more further layers can be arranged between the first 07 and the second layer 08.
- One or more layers, for example a lacquer or protective layer, can also be arranged on the side 09 of the layer 07.
- the configuration is that facing away from the cylinder 01 Surface of layer 08 with a Shore hardness of 60 ° to 80 ° possible, which allows the use of more aggressive colors and a stronger mechanical load on the surface.
- Layer 08 can u. U. also be a rubber plate with a relief 12 for flexographic printing.
- the relief 12 can be a negative or a positive shape, depending on the procedure.
- the outer layer 06 is designed as a printing form 06 for high or flexographic printing, the polymer plate 08 being applied directly to the plate 07 as the substrate 07 or as the carrier plate 07.
- the printing form 06 is produced from the sheet metal 07 and the polymer plate 08 or polymer layer 08 according to the doctoring principle and thus has very small thickness tolerances.
- Register devices 13, for example register pins 13, can be arranged on the lateral surface 02 of the cylinder 01 for the precisely fitting support and fastening of the substructure 04 and the printing form 06 during assembly.
- This arrangement of a register pin 13 on the outer surface 02 is particularly simple and allows an otherwise continuous outer surface 02. Due to the magnetic holding, the register device 13 does not have to perform a holding function in the radial direction.
- positions 04 and 06 on the lateral surface 02 can also be positioned in a register-exact manner, for example a stop in the circumferential and / or axial direction of the cylinder 01.
- the layers 04 and 06 can, for example, on a leading end, also be folded and be hooked with this bent end into a narrow channel running in the axial direction of the cylinder 01. By hanging or positioning the substructure 04 using the same register device 13, complicated positioning is avoided. A push of the respective layers 04; 06 on the lateral surface 02 can now be fixed in such a way that it lies in a narrow area and does not enlarge the non-printing area.
- register pins 13 are arranged on the lateral surface 02, corresponding recesses 14 and 16 are in the base 04 and in the printing form 06 Form of a slot or provided as a punch. Such recesses 14 and 16 are also provided if the register pins 13 are arranged in a channel opening or on a flat surface 02.
- the two layers 04 and 06 of this multi-layer elevator 03 can now be produced in a simple manner, since the dimensions of the layers 04 and 06, in particular a thickness d06 of the printing form 06, have become smaller in comparison with a single-layer structure of a multi-layer elevator.
- the thickness d06 is composed of a thickness d08 of the polymer layer 08, for example 0.3 ⁇ d08 ⁇ 1 mm, preferably between 0.9 mm and 1 mm, and a thickness d07 of the first layer 07, e.g. 0.1 mm ⁇ d07 ⁇ 0.3 mm, together. Accordingly, an overall thickness d06 of the printing form 06 of, for example, 0.4 mm ⁇ d06 ⁇ 1.3 mm is maintained.
- a thickness d04 of the compressible substructure 04 is, for example, between 0.3 mm and 0.7 mm, in a preferred embodiment between 0.4 mm and 0.6 mm. In addition, if the surfaces of the substructure 04 have to be covered, the thickness of the film is added. A length of the register pin 13 is larger than the thickness d04 and smaller than the sum of the thickness d04 and d06.
- the multi-layer elevator 03 consisting of the substructure 04 and the pressure plate 06, is assembled and fastened onto the cylinder 01 as follows: First, the loose substructure 04, possibly already provided with film on both sides, with its cutouts 14 in the cylinder 01 located register pins 13 inserted. This is used only for register-oriented alignment and securing against slipping in the circumferential direction of the cylinder 01 and not for radial fixation on the lateral surface 02.
- the substructure 04 is held radially on the lateral surface 02 by the printing form 06 which is now also used in register form.
- the printing form 06 is used here likewise inserted with their recesses 16 into the provided register pins and held on the lateral surface 02 of the cylinder 01 by interaction of the magnetic cylinder 01 with the metallic sheet 07.
- the two layers 04; 06 now preferably wound together on the circumference of the cylinder 01. This prevents creasing and unevenness of the base 04.
- the substructure 04 arranged between the printing form 06 and the lateral surface 02 is now held on the cylinder 01. It is no longer necessary to glue substructure 04 to cylinder 01 or glue substructure 04 to printing form 06.
- holding or releasing the multi-layer elevator 03 can advantageously take place by switching the current supplying the magnet on and off.

Such layer structures and intermediate layers differ significantly from those for printing plates in high pressure or flexographic printing.
Die US 46 28 815 A zeigt eine Vorrichtung zur Befestigung einer Druckplatte für den Flexodruck, wobei die metallische Platte im druckbaren Bereich durch eine elastische Schicht unterfüttert ist, und im nicht elastisch unterfütterten Bereich magnetisch am Zylinder gehalten ist.The US 46 28 815 A shows a device for fastening a printing plate for flexographic printing, the metallic plate being padded by an elastic layer in the printable area and being held magnetically on the cylinder in the non-padded area.
Die DE 38 32 515 A1 offenbart die Befestigung einer Druckplatte mit einem elastischen Unterlageboden, wobei der Unterlageboden Magnetpulver zum Zweck der Befestigung auf einer Zylinderoberfläche aufweist.DE 38 32 515 A1 discloses the attachment of a pressure plate with an elastic base, the base having magnetic powder for the purpose of attachment to a cylinder surface.
Die US 36 70 646 A zeigt eine Druckform für den Flexodruck, wobei die Druckform auf einem fest am Zylinder angeordneten Sattel angeordnet ist. Der Sattel weist im Bereich der Druckformenden in Umfangsrichtung Permanentmagneten auf, mittels derer die Enden der Druckform am Sattel gehalten werden.The US 36 70 646 A shows a printing form for flexographic printing, the printing form on a saddle fixed to the cylinder is arranged. In the area of the printing form ends, the saddle has permanent magnets in the circumferential direction, by means of which the ends of the printing form are held on the saddle.
In der US 40 40 351 A weist eine Druckplatte eine magnetisierbare Grundplatte und eine Gummischicht auf der Grundplatte auf.

The pressure plate can be attached to a magnetic cylinder by means of magnetic force.
Ein in der DE 34 14 533 A1 offenbarter Formzylinder weist zwischen der Druckform und seiner Mantelfläche eine Unterlage mit elastischen Eigenschaften auf. Die Druckform wird beispielsweise mittels Haftfolien gegen unerwünschte Ortsveränderung befestigt, und kann zusätzlich mittels Registerhilfsmitteln sicher positioniert werden.A forme cylinder disclosed in DE 34 14 533 A1 has a base with elastic properties between the printing form and its outer surface. The printing form is attached, for example, by means of adhesive films to prevent undesired changes in location, and can also be securely positioned using register aids.
Der Erfindung liegt die Aufgabe zugrunde, einen Aufzug eines Formzylinders einer Rotationsdruckmaschine zu schaffen.The invention has for its object to provide an elevator of a forme cylinder of a rotary printing press.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.
Vorteilhaft beim Befestigen eines Aufzuges auf Formzylindern von Rotationsdruckmaschinen, insbesondere einer Druckform eines Formzylinders für ein Hochdruck- oder Flexo-Druckwerk, ist die Anordnung eines elastischen Unterbaus zwischen der Druckform und dem Mantel des Zylinders. Dieser elastische Unterbau gleicht beispielsweise Toleranzen in der Dicke der Druckform und in der Rundlaufgenauigkeit des Zylinders aus. Bei überbreiten Zylindern eines Imprinterdruckwerkes für den Hoch- oder Flexodruck sollte vorteilhafter Weise unter der Druckform, i.d.R. einer Polymerplatte, ein derartiger Unterbau angeordnet werden. Dies gilt insbesondere auch dann, wenn ein erhöhter Verschleiß der Druckform, beispielsweise bei Verwendung spezieller, insbesondere aggressiver Farben vermieden werden soll. Dies wird beispielsweise mit einer erhöhten Härte für die Druckform - z. B. ca. 70 Shore -, in Verbindung mit dem erfindungsgemäßen Aufbau erreicht. In diesem Fall ist ein reversibel verformbarer, elastischer Unterbau von besonderem Vorteil um eine gleichmäßige Beaufschlagung der etwas härteren Druckform mit Farbe zu gewährleisten.The arrangement of an elastic substructure between the printing form and the jacket of the cylinder is advantageous when fastening an elevator on forme cylinders of rotary printing presses, in particular a printing form of a form cylinder for a high-pressure or flexographic printing unit. This elastic substructure compensates for tolerances in the thickness of the printing form and in the concentricity of the cylinder. In the case of extra-wide cylinders of an imprinter printing unit for high or flexographic printing, such a substructure should advantageously be arranged under the printing form, usually a polymer plate. This also applies in particular when there is increased wear on the printing form, for example when using special ones aggressive colors should be avoided. This is, for example, with increased hardness for the printing form - e.g. B. about 70 Shore - achieved in connection with the structure according to the invention. In this case, a reversibly deformable, elastic substructure is particularly advantageous in order to ensure that the somewhat harder printing form is evenly applied with ink.
Weiter ist es für einen schnellen Wechsel der Druckform, insbesondere für Zylinder eines Imprinterdruckwerkes, von Vorteil, die Druckform mittels Magnetkraft auf dem Mantel des Zylinders zu befestigen.Furthermore, for a quick change of the printing form, in particular for cylinders of an imprinter printing unit, it is advantageous to attach the printing form to the jacket of the cylinder by means of magnetic force.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass durch eine Ausführung des Aufzuges in mehreren Lagen, aus einer inneren Lage elastischen Materials, und einer äußeren, die Druckform mit ihrem erhabenen Relief tragenden Lage, eine vereinfachte Herstellung des Aufzuges, Qualitätsverbesserungen durch geringere Verformung und geringere Schwankung in der Toleranz als auch eine zumindest teilweise Wiederverwertbarkeit erreicht werden.The advantages that can be achieved with the invention consist in particular in that, by executing the elevator in several layers, consisting of an inner layer of elastic material and an outer layer that supports the printing form with its raised relief, simplified manufacture of the elevator, quality improvements due to less deformation and less fluctuation in tolerance as well as an at least partial recyclability can be achieved.
Ein wesentlicher, der genannten Vorteile ist, dass, insbesondere für Druckformen mit erhabenem Relief, eine Herstellung vereinfacht wird. Eine zweistufige Fertigung der Druckform, wobei beispielsweise eine Metallplatte zunächst abwicklungsgerecht vorgebogen und dann ein elastischer Unterbau aufgeklebt wird, ist nicht erforderlich, da die jeweilige Dicke in der geteilten Ausführung kleiner als die einer fest miteinander verbundenen mehrschichtigen Druckform, einer sogenannten Sandwichplatte, ist. Die Gefahr des Einfallens, wie sie beim Abrollen einer eben hergestellten Sandwichplatte mit elastischem Unterbau besteht, ist in vorteilhafter Weise nicht gegeben. Infolge dessen ist es möglich die Druckform eben, und damit deutlich kostengünstiger, herzustellen.An essential of the advantages mentioned is that production is simplified, in particular for printing forms with a raised relief. A two-stage production of the printing form, whereby, for example, a metal plate is first pre-bent for processing and then an elastic substructure is glued on, is not necessary since the thickness of the split version is smaller than that of a firmly connected, multi-layer printing form, a so-called sandwich plate. The risk of collapse, such as exists when a sandwich panel with an elastic substructure that has just been rolled off is advantageously not present. As a result, it is possible to produce the printing form evenly, and thus significantly more cost-effectively.
Vorteilhaft ist auch, dass eine Verbesserung der Druckqualität erreichbar ist, indem Verzerrungen, die aus dem Krümmungsradius beim Befestigen einer dicken, eben hergestellten und mehrschichtigen Druckform auf einem zylindrischen Körper resultieren, durch den nicht miteinander fest verbundenen, mehrlagigen Aufbau aus Druckform und Unterbau vermieden werden. Längungen des Druckbildes werden verkleinert. Insbesondere bei dicken Schichtaufbauten wie beispielsweise bei Hochdruck- bzw. Flexodruckverfahren, d. h. beim Druck mit merklich profilierter Oberfläche, macht sich beim Abrollen einer dicken, eben gefertigten einteiligen Druckform ein Übertragungsfehler bemerkbar.It is also advantageous that an improvement in print quality can be achieved by making distortions that arise from the radius of curvature when attaching a thick one Produced and multilayer printing form on a cylindrical body result, by the non-firmly connected, multilayer structure of printing form and substructure are avoided. Elongations of the printed image are reduced. Particularly in the case of thick layered structures such as, for example, high-pressure or flexographic printing processes, ie printing with a noticeably profiled surface, a transmission error becomes noticeable when a thick, one-piece printing form is just rolled off.
Auch für Verbundwerkstoffe spezifische Probleme, wie beispielsweise Schwankungen in der Toleranz der verschiedenen, fest zusammengefügten Teile und daraus resultierende wechselseitige Spannungen, aber auch der sich addierenden Dicketoleranzen werden vermieden. Zwischen den Lagen besteht in vorteilhafter Weise die Möglichkeit des Ausgleichs in Umfangsrichtung des Zylinders.Problems specific to composite materials, such as fluctuations in the tolerance of the different, firmly joined parts and the resulting mutual stresses, but also the thickness tolerances that add up, are avoided. Between the layers there is advantageously the possibility of compensation in the circumferential direction of the cylinder.
Bei Montage des Aufzugs können die beiden Lagen im Bereich eines Endes in eine Registereinrichtung für die Druckform eingehängt werden, und anschließend beide auf die Mantelfläche aufgezogen werden. So wird Faltenbildung vermieden und ein Aufeinanderliegen der entstehenden Stöße ermöglicht.When assembling the elevator, the two layers can be hung in the area of one end in a register device for the printing form, and then both can be drawn onto the outer surface. This prevents wrinkles and allows the resulting bumps to lie one on top of the other.
Vorteilhaft an der Ausführung des mehrlagigen Aufzuges ist weiter, dass der nicht fest mit der Druckform, beispielsweise einer auf einem Blech angeordneten Polymerplatte, verbundene elastische Unterbau weiterverwendbar bleibt, während beispielsweise nur die das Relief enthaltende Druckform ausgetauscht wird.Another advantage of the design of the multi-layer elevator is that the elastic substructure which is not firmly connected to the printing form, for example a polymer plate arranged on a sheet, remains usable, while, for example, only the printing form containing the relief is replaced.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.
Die einzige Zeichnung zeigt eine schematische Darstellung für die Befestigung eines mehrlagig aufgebauten Aufzuges auf einem Formzylinder.The only drawing shows a schematic representation for the attachment of a multi-layer elevator to a forme cylinder.
In einer Rotationsdruckmaschine, z. B. einer Hochdruck- bzw. Flexodruckmaschine, ist ein Formzylinder 01, angeordnet, welcher auf seiner Mantelfläche 02 zumindest magnetische Bereiche aufweist. Das magnetische Feld kann hierbei durch Permanentmagneten oder auch durch Elektromagneten erzeugt sein. Vorteilhaft ist die Verwendung von Magneten, insbesondere Permanentmagneten, hoher Magnetkraft.In a rotary printing machine, e.g. B. a high-pressure or flexographic printing machine, a forme cylinder 01 is arranged, which has at least magnetic areas on its outer surface 02. The magnetic field can be generated by permanent magnets or by electromagnets. The use of magnets, in particular permanent magnets, of high magnetic force is advantageous.
Auf der Mantelfläche 02 des Formzylinders 01 der Rotations-Hochdruck- bzw. Flexodruckmaschine wird ein mehrlagiger Aufzug 03 befestigt. Der mehrlagige Aufzug 03 besteht im wesentlichen aus einer inneren Lage 04, beispielsweise einem elastischen Unterbau 04, und einer äußeren Lage 06, in Form einer einer Druckform 06. Der Unterbau 04 befindet sich im montierten Zustand auf der Mantelfläche 02 zwischen der Mantelfläche 02 und der Druckform 06.A multi-layer elevator 03 is attached to the lateral surface 02 of the forme cylinder 01 of the rotary high-pressure or flexographic printing machine. The multilayer elevator 03 essentially consists of an inner layer 04, for example an elastic substructure 04, and an outer layer 06, in the form of a printing form 06. The substructure 04 is located on the outer surface 02 between the outer surface 02 and the outer surface 04 Printing form 06.
Der Unterbau 04 besteht aus einem reversibel verformbaren und/oder elastischen, in vorteilhafter Ausführung kompressiblem Material oder weist zumindest, bei mehrschichtigem Aufbau, eine elastische, kompressible Schicht auf. Im Beispiel ist der Unterbau 04 einschichtig, kompressibel und geschlossenporig ausgeführt. Durch Verwendung geschlossenporiger Materialen für die kompressible Schicht des Unterbaus 04 ist eine zweite Schicht zum Schutz der Poren gegen Feuchtigkeit, Farbe und Schmutz nicht erforderlich.The substructure 04 consists of a reversibly deformable and / or elastic, in an advantageous embodiment compressible material or at least, in the case of a multilayer structure, has an elastic, compressible layer. In the example, the substructure 04 is single-layer, compressible and closed-pore. By using closed-pore materials for the compressible layer of the substructure 04, a second layer to protect the pores against moisture, color and dirt is not necessary.
Grundsätzlich ist jedoch auch ein mehrschichtiger Aufbau des Unterbaus 04 geeignet, wobei, insbesondere bei Verwendung von offenporigen Materialien als kompressible Schicht, ein Abdecken der offenen Poren durch eine zweite, nicht dargestellte Schicht vorgesehen ist. Vorteilhaft bei Verwendung offenporiger Zellstrukturen, wie z. B. Polyurethan-Elastomeren, ist eine Abdeckung gegen Eindringen von Feuchtigkeit der offenporigen Oberfläche durch einen Kunststoff wie beispielsweise eine Folie aus Polyester. Diese Abdeckung kann beidseitig der kompressiblen Schicht, vorzugsweise stoffschlüssig mit dieser verbunden, erfolgen.Basically, however, a multi-layer structure of the substructure 04 is also suitable, wherein, particularly when using open-pore materials as a compressible layer, the open pores are covered by a second layer, not shown is provided. Advantageous when using open-pore cell structures, such as. B. polyurethane elastomers, is a cover against moisture penetration of the open-cell surface by a plastic such as a film made of polyester. This cover can be provided on both sides of the compressible layer, preferably integrally connected to it.
Die Druckform 06, beispielsweise eine Druckform 06 für den Hoch- oder Tiefdruck, ist mehrschichtig aufgebaut und weist eine dem Unterbau 04 zugewandte erste Schicht 07 und eine mit der ersten Schicht 07 form- oder stoffschlüssig verbundene zweite Schicht 08 auf. Die erste Schicht 07 der äußeren Lage 06 weist, zumindest bereichsweise, auf ihrer der Mantelfläche 02 des Zylinders 01 zugewandten Seite 09, ein magnetisch anziehbares, vorzugsweise einen ferromagnetischen Stoff enthaltendes, Material auf. Im Beispiel ist die erste Schicht 07 als metallisches Blech 07 ausgeführt, welches durch die magnetische Kraft zur Mantelfläche 02 des Zylinders 01 angezogen wird. Grundsätzlich ist es jedoch auch möglich, die Mantelfläche 02 des Zylinders 01 aus magnetisch anziehbarem Material, und die Schicht 07 aus magnetischem Material auszuführen, damit sich die Lage 06 und die Mantelfläche 02 magnetisch anziehen.The printing form 06, for example a printing form 06 for high or low pressure, has a multilayer structure and has a first layer 07 facing the substructure 04 and a second layer 08 which is connected to the first layer 07 in a form-fitting or material-locking manner. The first layer 07 of the outer layer 06 has, at least in some areas, on its side 09 facing the outer surface 02 of the cylinder 01, a magnetically attractable material, preferably containing a ferromagnetic material. In the example, the first layer 07 is designed as a metal sheet 07, which is attracted to the lateral surface 02 of the cylinder 01 by the magnetic force. In principle, however, it is also possible to design the outer surface 02 of the cylinder 01 from magnetically attractable material and the layer 07 from magnetic material so that the layer 06 and the outer surface 02 attract magnetically.
Auf einer der Mantelfläche 02 des Zylinders 01 abgewandten Seite 11 des Bleches 07 ist die zweite, beim Druckvorgang mit einem zweiten Zylinder oder einem Bedruckstoff zusammen wirkende Schicht 08 angeordnet. Die Schicht 08 ist als Polymerplatte 08 für den Hoch- bzw. Flexodruck ausgebildet, wobei sie auf ihrer dem Blech 07 abgewandten Seite ein aus der Schicht 08 heraus ragendes, druckendes Relief 12 aufweist. Zwischen erster 07 und zweiter Schicht 08 können noch eine oder mehrere weitere Schichten angeordnet sein. Auch auf der Seite 09 der Schicht 07 können noch eine oder mehrere Schichten, beispielsweise eine Lack- oder Schutzschicht angeordnet sein. Bei Anordnung eines elastischen Unterbaus 04 ist die Ausbildung der vom Zylinder 01 abgewandten Oberfläche der Schicht 08 mit einer Shore-Härte von 60° bis 80° möglich, was die Verwendung aggressiverer Farben und eine stärkere mechanische Belastung der Oberfläche erlaubt. Die Schicht 08 kann u. U. auch eine Gummiplatte mit einem Relief 12 für den Flexodruck sein. Das Relief 12 kann je nach Verfahrensweise eine Negativ- oder eine Positivform darstellen. Im Beispiel ist die äußere Lage 06 als Druckform 06 für den Hoch- oder Flexodruck ausgebildet, wobei die Polymerplatte 08 direkt auf dem Blech 07 als Untergrund 07 bzw. als Trägerplatte 07 aufgebracht ist. In vorteilhafter Ausführung wird die Druckform 06 aus dem Blech 07 und der Polymerplatte 08 bzw. Polymerschicht 08 nach dem Abrakelprinzip hergestellt und weist somit sehr geringe Dicketoleranzen auf.On a side 11 of the plate 07 facing away from the lateral surface 02 of the cylinder 01, the second layer 08, which cooperates with a second cylinder or a printing material during the printing process, is arranged. The layer 08 is designed as a polymer plate 08 for high-pressure or flexographic printing, and on its side facing away from the plate 07 it has a printing relief 12 projecting out of the layer 08. One or more further layers can be arranged between the first 07 and the second layer 08. One or more layers, for example a lacquer or protective layer, can also be arranged on the side 09 of the layer 07. If an elastic substructure 04 is arranged, the configuration is that facing away from the cylinder 01 Surface of layer 08 with a Shore hardness of 60 ° to 80 ° possible, which allows the use of more aggressive colors and a stronger mechanical load on the surface. Layer 08 can u. U. also be a rubber plate with a relief 12 for flexographic printing. The relief 12 can be a negative or a positive shape, depending on the procedure. In the example, the outer layer 06 is designed as a printing form 06 for high or flexographic printing, the polymer plate 08 being applied directly to the plate 07 as the substrate 07 or as the carrier plate 07. In an advantageous embodiment, the printing form 06 is produced from the sheet metal 07 and the polymer plate 08 or polymer layer 08 according to the doctoring principle and thus has very small thickness tolerances.
Für die passgenaue Auflage und Befestigung des Unterbaus 04 und der Druckform 06 bei der Montage können auf der Mantelfläche 02 des Zylinders 01 Registereinrichtungen 13, beispielsweise Registerstifte 13 angeordnet sein. Diese Anordnung eines Registerstiftes 13 auf der Mantelfläche 02 ist besonders einfach und läßt eine ansonsten durchgehende Mantelfläche 02 zu. Aufgrund des magnetischen Haltens hat die Registereinrichtung 13 keine Haltefunktion in radialer Richtung zu leisten. Anstelle von Registerstiften 13 kann auch in anderer Weise für eine registergenaue Positionierung der Lagen 04 und 06 auf der Mantelfläche 02 gesorgt werden wie beispielsweise einem Anschlag in Umfangs- und/oder in axialer Richtung des Zylinders 01. Die Lagen 04 und 06 können, beispielsweise an einem vorlaufenden Ende, auch abgekantet sein und mit diesem abgekanteten Ende in einen schmalen, in axialer Richtung des Zylinders 01 verlaufendem Kanal eingehängt sein. Durch das Einhängen bzw. Positionieren des Unterbaus 04 mittels derselben Registereinrichtung 13, wird ein aufwendiges Positionieren vermieden. Ein Stoß der jeweiligen Lagen 04; 06 auf der Mantelfläche 02 ist nun derart festlegbar, daß er in einem engen Bereich liegt und den nichtdruckenden Bereich nicht vergrößert.Register devices 13, for example register pins 13, can be arranged on the lateral surface 02 of the cylinder 01 for the precisely fitting support and fastening of the substructure 04 and the printing form 06 during assembly. This arrangement of a register pin 13 on the outer surface 02 is particularly simple and allows an otherwise continuous outer surface 02. Due to the magnetic holding, the register device 13 does not have to perform a holding function in the radial direction. Instead of register pins 13, positions 04 and 06 on the lateral surface 02 can also be positioned in a register-exact manner, for example a stop in the circumferential and / or axial direction of the cylinder 01. The layers 04 and 06 can, for example, on a leading end, also be folded and be hooked with this bent end into a narrow channel running in the axial direction of the cylinder 01. By hanging or positioning the substructure 04 using the same register device 13, complicated positioning is avoided. A push of the respective layers 04; 06 on the lateral surface 02 can now be fixed in such a way that it lies in a narrow area and does not enlarge the non-printing area.
Sind, wie im Beispiel dargestellt, Registerstifte 13 auf der Mantelfläche 02 angeordnet, so sind im Unterbau 04 und in der Druckform 06 entsprechende Ausnehmungen 14 und 16 in Form eines Schlitzes oder als Stanzung vorgesehen. derartige Ausnehmungen 14 und 16 sind auch vorgesehen, wenn die Registerstifte 13 in einer Kanalöffnung oder auf einer Abflachung der Mantelfläche 02 angeordnet sind.If, as shown in the example, register pins 13 are arranged on the lateral surface 02, corresponding recesses 14 and 16 are in the base 04 and in the printing form 06 Form of a slot or provided as a punch. Such recesses 14 and 16 are also provided if the register pins 13 are arranged in a channel opening or on a flat surface 02.
Eine Herstellung der beiden Lagen 04 und 06 dieses mehrlagigen Aufzuges 03 kann nun in einfacher Weise eben erfolgen, da die Abmessungen der Lagen 04 und 06, insbesondere eine Dicke d06 der Druckform 06 im Vergleich zu einem einlagigen Aufbau eines mehrschichtigen Aufzuges kleiner geworden ist. Die Dicke d06 setzt sich aus einer Dicke d08 der Polymerschicht 08, beispielsweise 0,3 < d08 < 1 mm, vorzugsweise zwischen 0,9 mm und 1 mm, und einer Dicke d07 der ersten Schicht 07, z.B. 0,1 mm < d07 < 0,3 mm, zusammen. Demzufolge wird eine gesamte Dicke d06 der Druckform 06 von beispielsweise 0,4 mm <d06 < 1,3 mm eingehalten. Eine Dicke d04 des kompressiblen Unterbaus 04 liegt beispielsweise zwischen 0, 3 mm und 0,7 mm, in bevorzugter Ausführung zwischen 0,4 mm und 0,6 mm. Hinzu kommt, falls die Oberflächen des Unterbaus 04 abgedeckt werden müssen, jeweils die Dicke der Folie. Eine Länge des Registerstiftes 13 ist größer als die Dicke d04 und kleiner als die Summe der Dicke d04 und d06.The two layers 04 and 06 of this multi-layer elevator 03 can now be produced in a simple manner, since the dimensions of the layers 04 and 06, in particular a thickness d06 of the printing form 06, have become smaller in comparison with a single-layer structure of a multi-layer elevator. The thickness d06 is composed of a thickness d08 of the polymer layer 08, for example 0.3 <d08 <1 mm, preferably between 0.9 mm and 1 mm, and a thickness d07 of the first layer 07, e.g. 0.1 mm <d07 <0.3 mm, together. Accordingly, an overall thickness d06 of the printing form 06 of, for example, 0.4 mm <d06 <1.3 mm is maintained. A thickness d04 of the compressible substructure 04 is, for example, between 0.3 mm and 0.7 mm, in a preferred embodiment between 0.4 mm and 0.6 mm. In addition, if the surfaces of the substructure 04 have to be covered, the thickness of the film is added. A length of the register pin 13 is larger than the thickness d04 and smaller than the sum of the thickness d04 and d06.
Eine Montage und die Befestigung des mehrlagigen Aufzuges 03, bestehend aus dem Unterbau 04 und der Druckplatte 06 auf den Zylinder 01 erfolgt folgendermaßen: Zunächst wird der lose Unterbau 04, ggf. beidseitig bereits mit Folie versehen, mit seinen Aussparungen 14 in die am Zylinder 01 befindlichen Registerstifte 13 eingelegt. Dies dient ausschließlich dem registerhaltigen Ausrichten und dem Sichem gegen Verrutschen in Umfangsrichtung des Zylinders 01 und nicht zur radialen Fixierung auf der Mantelfläche 02. Auf der Mantelfläche 02 radial gehalten wird der Unterbau 04 durch die nun ebenfalls registerhaltig eingesetzte Druckform 06. Die Druckform 06 wird hierbei ebenfalls mit ihren Aussparungen 16 in die vorgesehenen Registerstifte eingesetzt und durch Wechselwirkung des magnetischen Zylinders 01 mit dem metallischen Blech 07 an der Mantelfläche 02 des Zylinders 01 gehalten. Die beiden Lagen 04; 06 werden nun vorzugsweise gemeinsam auf dem Umfang des Zylinders 01 gewickelt. Hierdurch wird eine Faltenbildung und Ungleichmäßigkeit des Unterbaus 04 vermieden. Der zwischen Druckform 06 und Mantelfläche 02 angeordnete Unterbau 04 wird nun am Zylinder 01 gehalten. Ein Kleben des Unterbaues 04 auf den Zylinder 01 oder das verkleben von Unterbau 04 mit der Druckform 06 ist nicht mehr erforderlich. Bei Verwendung von Elektromagneten zur Erzeugung des Magnetfeldes auf der Mantelfläche 02 kann ein Halten bzw. Lösen des mehrlagigen Aufzuges 03 in vorteilhafter Weise durch Ein- und Ausschalten des den Magneten versorgenden Stromes erfolgen.The multi-layer elevator 03, consisting of the substructure 04 and the pressure plate 06, is assembled and fastened onto the cylinder 01 as follows: First, the loose substructure 04, possibly already provided with film on both sides, with its cutouts 14 in the cylinder 01 located register pins 13 inserted. This is used only for register-oriented alignment and securing against slipping in the circumferential direction of the cylinder 01 and not for radial fixation on the lateral surface 02. The substructure 04 is held radially on the lateral surface 02 by the printing form 06 which is now also used in register form. The printing form 06 is used here likewise inserted with their recesses 16 into the provided register pins and held on the lateral surface 02 of the cylinder 01 by interaction of the magnetic cylinder 01 with the metallic sheet 07. The two layers 04; 06 now preferably wound together on the circumference of the cylinder 01. This prevents creasing and unevenness of the base 04. The substructure 04 arranged between the printing form 06 and the lateral surface 02 is now held on the cylinder 01. It is no longer necessary to glue substructure 04 to cylinder 01 or glue substructure 04 to printing form 06. When using electromagnets to generate the magnetic field on the outer surface 02, holding or releasing the multi-layer elevator 03 can advantageously take place by switching the current supplying the magnet on and off.
