Auf ihre strukturierte Fläche ist eine dünne, die Mikrorauhheit ausgleichende Chromschicht (7) aufgebracht. Diese Chromschicht verbessert das Anlaufverhalten der bogenführenden Folie und verlängert deren Lebensdauer, insbesondere aber wird das gute Farbabgabeverhalten über die gesamte Lebensdauer der Folie annähernd konstant gehalten.A sheet-guiding film, one surface of which is smooth and the opposite surface of which is provided with statically uniformly distributed, equally high spherical caps (3), serves as an elevator for impression cylinders of rotary offset printing machines for perfecting. The film consists of two layers. The carrier layer (6) is made of chemically resistant, wear-resistant and unyielding material. It has good ink release behavior. A thin chrome layer (7) which compensates for the micro-roughness is applied to its structured surface. This chrome layer improves the tarnishing behavior of the sheet-guiding film and extends its service life, but in particular the good ink delivery behavior is kept almost constant over the entire service life of the film.

Description

Die Erfindung betrifft eine bogenführende Folie als Aufzug für Gegendruckzylinder von Rotations-Offsetdruckmaschinen für Schön- und Widerdruck, deren eine Fläche glatt ausgebildet und deren gegenüberliegende Fläche mit statistisch gleichmäßig verteilten, gleich hohen Kugelkalotten versehen ist.The invention relates to a sheet-guiding film as an elevator for impression cylinders of rotary offset printing machines for perfecting, one surface of which is smooth and the opposite surface of which is provided with statistically uniformly distributed, equally high spherical caps.

Nach der DE-PS 12 58 873 ist bekannt, ein Aluminiumblech oder die Mantelfläche von Widerdruck- bzw. Bogenführungszylindern beispielsweise durch Sandstrahlen aufzurauhen und dann mit einer dünnen Chromschicht zu überziehen. Die tragenden Flächenteile der so geschaffenen Fläche sind unregelmäßig hoch und verschieden groß. Relativ spitze Tragflächen werden naturgemäß vom Papier schneller abgenutzt sein als flächige. An den abgenutzten Stellen kommt das Trägermaterial, z. B. Stahl oder Aluminium, zum Vorschein. Das Farbabgabeverhalten dieser freigelegten Flächen des Trägermaterials ist derart schlecht, daß die gesamte Mantelfläche zur Führung von frisch bedruckten Bogenseiten bei Schön- und Widerdruck nicht mehr taugt. Außerdem dringen an diesen stark abgenutzten Flächenteilen die beim Offsetverfahren verwendeten chemischen Mittel ein. Es kommt zum Korrodieren.According to DE-PS 12 58 873 it is known to roughen an aluminum sheet or the outer surface of counterpressure or sheet guiding cylinders, for example by sandblasting, and then to coat it with a thin chrome layer. The load-bearing parts of the surface created in this way are irregularly high and of different sizes. Relatively pointed wings will naturally wear out of paper faster than flat ones. At the worn areas, the carrier material, e.g. B. steel or aluminum, to the fore. The ink release behavior of these exposed surfaces of the carrier material is so poor that the entire outer surface is no longer suitable for guiding freshly printed sheet pages in perfecting. In addition, the chemical agents used in the offset process penetrate these heavily worn areas. It corrodes.

Durch die DE-OS 28 20 549 ist ferner eine metallische Bogenführungsfolie bekannt geworden, die mindestens zwei Schichten aufweist. Eine Trägerschicht aus Aluminium oder Kupfer ist einseitig durch Sandbestrahlung aufgerauht und vernickelt. Auf diese zweite Schicht aus Nickel kann noch eine weitere dünne Lage aus Hartnickel aufgetragen sein.From DE-OS 28 20 549 a metallic sheet guide film is also known, which has at least two layers. A support layer made of aluminum or copper is roughened on one side by sandblasting and nickel-plated. Another thin layer of hard nickel can be applied to this second layer of nickel.

Das Aufrauhen der Trägerschicht mit Hilfe eines Sandstrahlverfahrens erzeugt tragende Flächen, die ungleich hoch und verschieden groß sind. Die während des Druckprozesses von der druckfrischen Bogenunterseite abgenommene Farbe wird daher unregelmäßig beim Verlassen des Druckspaltes wieder abgegeben. Es kommt zu Farbumverteilungen und damit zur Verschlechterung des Druckbildes. Ferner bietet eine solche Bogenführungsfläche aufgrund zu großer und zu unterschiedlicher Täler eine unzureichende Unterlage für den Bogen beim Aufbringen des Widerdrucks.Roughening the support layer with the help of a sandblasting process creates load-bearing surfaces that are unevenly high and different that are big. The ink removed from the freshly printed underside of the sheet during the printing process is therefore released irregularly when it leaves the printing nip. Color redistribution occurs and the print image deteriorates. Furthermore, such a sheet guiding surface provides an inadequate base for the sheet when applying the counterpressure due to the valleys being too large and too different.

Eine dreischichtige Bogenführungsfläche hat überdies den Nachteil, daß die Struktur der aufgerauhten Oberfläche eine Abschwächung erfährt. Die Täler werden enger und die tragenden Hochplateaus größer. Dies hat zur Folge, daß sich bei einer dreischichtigen Bogenführungsfolie das Farbabgabeverhalten verschlechtert. Darüberhinaus ist es schwierig, die dreischichtigen Bogenführungsfolien an den Enden zwecks Einspannen abzubiegen, da die Hartnickelschicht dabei reißt.A three-layer sheet guiding surface also has the disadvantage that the structure of the roughened surface is weakened. The valleys become narrower and the load-bearing plateaus become larger. The result of this is that the ink release behavior deteriorates in the case of a three-layer sheet guiding film. In addition, it is difficult to bend the three-layer sheet guiding films at the ends for the purpose of clamping, since the hard nickel layer tears in the process.

Aufgabe der Erfindung ist es, die Lebensdauer der bogenführenden Folien zu verlängern, deren Farbabgabeverhalten zu verbessern und vor allem deren Farbabgabeverhalten über die gesamte Lebensdauer der Folie annähernd konstant zu halten.The object of the invention is to extend the life of the sheet-guiding films, to improve their ink-release behavior and, above all, to keep their color-release behavior approximately constant over the entire life of the film.

Gelöst wird die Aufgabe dadurch, daß auf die strukturierte Fläche einer chemisch beständigen, verschleißfesten und unnachgiebigen Trägerschicht mit gutem Farbabgabeverhalten eine dünne, die Mikrorauheit ausgleichende Chromschicht aufgebracht ist.The object is achieved in that a thin, micro-roughness-compensating chromium layer is applied to the structured surface of a chemically resistant, wear-resistant and unyielding carrier layer with good ink release behavior.

Das Farbabgabeverhalten einer Fläche ist abhängig von ihrer Struktur und ihrem Material. Die Ausbildung der tragenden Flächen als Kugelkalotten begünstigt das Abziehen angenommener Farbe. Materialien wie Chrom, Nickel, Chromnickelstahl oder bestimmte Kunststoffe begünstigen zusätzlich die Farbabgabe.The color release behavior of a surface depends on its structure and material. The formation of the load-bearing surfaces as spherical spheres favors the removal of the assumed color. Materials such as chrome, nickel, chromium-nickel steel or certain plastics additionally promote color delivery.

Die Trägerschicht kann deshalb beispielsweise aus einer mittels Galvanoformung hergestellten Nickelfolie, einem durch Ätzen oder Prägen bearbeiteten Chromnickelstahlblech oder aus gepreßten Kunststoffolien mit hohem Elastizitätsmodul, z. B. Hartpolyamidfolien, bestehen. Die aufgebrachte Chromschicht kann beispielsweise eine Dicke von 0,01 bis 0,03 mm aufweisen. Sie gleicht die Mikrorauhheit einer Nickel-, Chromnickelstahl- oder Kunststoffschicht weitgehend aus und bietet somit eine glattere Oberfläche als die Trägerschicht.The carrier layer can therefore, for example, from a nickel foil produced by means of electroforming, a chromium-nickel steel sheet processed by etching or embossing, or from pressed plastic foils with a high modulus of elasticity, e.g. B. hard polyamide films exist. The applied chrome layer can have a thickness of 0.01 to 0.03 mm, for example. It largely compensates for the micro-roughness of a nickel, chromium-nickel steel or plastic layer and thus offers a smoother surface than the carrier layer.

Dies hat zur Folge, daß eine verchromte, bogenführende Folie schon in der Anfahrzeit bestes Farbabgabeverhalten zeigt sowie schneller zu waschen ist, als die anfangs etwas rauhere Trägerschicht.The consequence of this is that a chrome-plated, sheet-guiding film already shows the best ink release behavior in the start-up time and is easier to wash than the initially somewhat rougher carrier layer.

Vor allem aber wird die Lebensdauer der bogenführenden Folie um die Standzeit der sehr harten Chromschicht verlängert. Dabei bleibt das Farbabgabeverhalten einer solchen verchromten, bogenführenden Folie praktisch über die gesamte Lebensdauer konstant, weil nach dem Verschleiß der sehr dünnen Chromschicht an den bogentragenden Flächenteilen die zum Vorschein kommende Trägerschicht gleichfalls gute Farbabgabeeigenschaften aufweist.Above all, however, the life of the sheet-guiding film is extended by the life of the very hard chrome layer. The ink release behavior of such a chrome-plated, sheet-guiding film remains practically constant over the entire service life, because after the wear of the very thin chrome layer on the sheet-bearing surface parts, the carrier layer that appears also has good ink release properties.

Besonders vorteilhaft ist die Verwendung von purem Nickel als Trägerschicht, weil sich die chemische Beständigkeit von Chrom und Nickel gegenüber den im Offsetdruck verwendeten Chemikalien ergänzen. So kann beispielsweise die dünne Chromschicht Durch Aufbringen von Rapidschwärzer beschädigt werden. Nickel ist jedoch gegen Rapidschwärzer beständig. Andererseits greifen bestimmte Wischwasserzusätze u. U. in Verbindung mit örtlichem Leitungswasser Nickel an. Chrom widersteht diesen Chemikalien. Die dünne Chromschicht verhindert also bei Verwendung ungünstiger Wischwasserzusätze den frühzeitigen Verschleiß einer Nickelfolie.The use of pure nickel as a carrier layer is particularly advantageous because the chemical resistance of chromium and nickel is complementary to the chemicals used in offset printing. For example, the thin chrome layer Damaged by applying rapid blacker. However, nickel is resistant to rapid blackers. On the other hand, certain washer fluid additives U. in connection with local tap water nickel. Chromium resists these chemicals. The thin chrome layer prevents the premature wear of a nickel foil when using unfavorable cleaning water additives.

Da die dünne Chrom schicht nicht nur hart, sondern auch spröde ist, würde sie beim Abkanten der Einspannenden einer bogenführenden Folie sehr leicht abplatzen. Aus diesem Grunde ist es vorteilhaft, die Trägerschicht an den Einspannenden abzukanten, bevor die Chromschicht aufgebracht wird.Since the thin chrome layer is not only hard, but also brittle, it would flake off very easily if the clamping end of a sheet-guiding film was bent. For this reason, it is advantageous to fold the carrier layer on the clamping ends before the chrome layer is applied.

Die Erfindung wird im folgenden durch ein Ausführungsbeispiel anhand der Zeichnung näher erläutert.The invention is explained in more detail below by an embodiment with reference to the drawing.

Es zeigt:

  • Fig. 1 einen Ausschnitt der strukturierten Fläche einer bogentragenden Folie nach der Erfindung,
  • Fig. 2 den Schnitt A-B durch diesen Folienausschnitt und
  • Fig. 3 den Schnitt C-D durch denselben Folienausschnitt.
It shows:
  • 1 shows a detail of the structured surface of an arch-carrying film according to the invention,
  • Fig. 2 shows the section AB through this film section and
  • Fig. 3 shows the section CD through the same film section.

Wie man aus der Fig. 1 ersehen kann, ist die strukturierte Fläche 1 der bogenführenden Folie 2 von Tragflächen in Form von Kugelkalotten 3 übersät. Diese Kugelkalotten 3 sind statistisch gleichmäßig verteilt angeordnet, d. h. ihre Verteilung ist nicht symmetrisch, nähert sich jedoch der Symmetrie. Statistisch gleichmäßig bedeutet auch, daß auf einer Flächeneinheit etwa die gleiche Anzahl von Kugelkalotten 3 vorgesehen wird. Dadurch ist gewährleistet, daß die Zwischenräume, die Täler 4, hinsichtlich ihrer Größe und Gestalt nicht wesentlich voneinander abweichen. Grundsätzlich ist also auch eine gleichförmige Unterlage eines zu bedruckenden Bogens gewährleistet.As can be seen from FIG. 1, the structured surface 1 of the sheet 2 guiding the sheet is covered with wings in the form of spherical caps 3. These spherical caps 3 are arranged in a statistically uniform distribution, ie their distribution is not symmetrical, but approximates symmetry. Statistically even also means that approximately the same number on one unit of area of spherical caps 3 is provided. This ensures that the gaps, the valleys 4, do not differ significantly in size and shape. Basically, a uniform base of a sheet to be printed is also guaranteed.

Wie aus den Figuren 2 und 3 zu entnehmen ist, sind die Kugelkalotten 3 alle gleich hoch. Die Kuppen der Kugelkalotten 3 bilden somit eine Tragebene 5. Die Kalottenform der Tragflächen und die Bildung der Tragebene 5 gewährleisten eine ausgezeichnete Abstützung des auf der anderen Seite zu bedruckenden Bogens. Diese Anordnung der Kugelkalotten 3 verhindert außerdem das vorzeitige Abnutzen höher stehender Tragflächen, wie es bei bekannten, bogentragenden Folien der Fall ist.As can be seen from FIGS. 2 and 3, the spherical caps 3 are all of the same height. The domes of the spherical caps 3 thus form a supporting plane 5. The spherical shape of the supporting surfaces and the formation of the supporting plane 5 ensure excellent support of the sheet to be printed on the other side. This arrangement of the spherical caps 3 also prevents premature wear of higher-lying wings, as is the case with known sheet-supporting foils.

Die bogenführende Folie 2 besteht gemäß Figur 2 aus zwei Schichten, nämlich der Trägerschicht 6 aus Nickel und der Deckschicht 7 aus Chrom. Die Trägerschicht 6 kann beispielsweise durch Galvanoformung hergestellt werden, wobei allerdings die tragenden Kuppen noch eine relativ große Mikrorauheit aufweisen. In einem anderen Bad kann die dünne Chromschicht 7 aufgebracht werden. Sie wird an ihrer Oberfläche wesentlich glatter als die Trägerschicht 6. Dadurch hat eine solche bogentragende Folie vom Beginn der Nutzung an ein gleich gutes Farbabgabeverhalten, während bei der Nutzung der Trägerfolie allein erst nach einer gewissen Glättung der Mikrorauheit das optimale Farbabgabeverhalten erzielt wird. Auch läßt sich die verchromte Oberfläche besser waschen als die geringfügig rauhere Fläche der Trägerschicht 6.2, the sheet-guiding film 2 consists of two layers, namely the carrier layer 6 made of nickel and the cover layer 7 made of chrome. The carrier layer 6 can be produced, for example, by electroforming, although the load-bearing tips still have a relatively high level of micro roughness. The thin chrome layer 7 can be applied in another bath. Its surface becomes much smoother than the carrier layer 6. As a result, such a sheet-bearing film has an equally good color release behavior from the start of use, while when using the support film alone, the optimal color release behavior is achieved only after a certain smoothing of the micro-roughness. The chrome-plated surface can also be washed better than the slightly rougher surface of the carrier layer 6.

Nach Herstellung der Trägerschicht 6 mittels Galvanoformung sind zunächst die Einspannkanten 8 abzubiegen, bevor im Chrombad die Deckschicht 7 aufgebracht wird.After production of the carrier layer 6 by means of electroforming The clamping edges 8 must first be bent before the cover layer 7 is applied in the chrome bath.

Das Ausführungsbeispiel kann insofern Abwandlungen erfahren, als statt der durch Galvanoformung hergestellten Trägerschicht 6 aus Nickel ein geprägtes bzw. geätztes Chrom-Nickel-Stahlblech oder eine geprägte bzw. geätzte Kunststoffolie, z. B. ein in Bezug auf gutes Farbabgabeverhalten geeignetes Hartthermoplast,aus PVC, Polyester, Polyamid oder Glas Verwendung findet. Der Thermoplast muß jedoch einen hohen Elastizitätsmodul aufweisen, weil er andernfalls im Druckspalt aufgrund des Walkprozesses nachgeben würde und das Breiterdrucken hervorriefe.The exemplary embodiment can be modified insofar as, instead of the carrier layer 6 made of nickel produced by electroforming, an embossed or etched chromium-nickel steel sheet or an embossed or etched plastic film, eg. B. a suitable in terms of good color delivery hard thermoplastic made of PVC, polyester, polyamide or glass is used. However, the thermoplastic must have a high modulus of elasticity, because otherwise it would give way in the printing nip due to the flexing process and would cause wider printing.
