Abstract

The device uses a foil (4) of e.g. Cr steel wrapped around a rubber-coated cylinder (3) between the platen (1) and pressure roller (2). The foil carries two bumps riveted (14) or adhesively bonded to opposite sides, enabling it to be stretched by a tensioning device (16). An underlay (15) e.g. 1.65 mm thick on a 0.3 mm foil makes up the overall thickness to the 1.95 mm of the standard rubber coating commonly used for the same purpose.

Description

Die vorliegende Erfindung bezieht sich auf eine Gegendruck-Vorrichtung für die Durchführung von Perforationen und/oder Stanzungen an Offset-Bogenmaschinen.The present invention relates to a counterpressure device for performing perforations and / or punchings on offset sheet-fed machines.

Bei Offset-Bogenmaschinen ist der mit dem Druckzylinder - auch Gegendruckzylinder genannt - zusammenarbeitende Gummituchzylinder mit einem Gummituch versehen und steht mit einem definierten Druck gegen den Druckzylinder. Zur Erzeugung von Perforationen wird der Druckzylinder mit einem Perforationsband bespannt, während das Gummituch unverändert auf dem Gummituchzylinder belassen wird. Das Gummituch hat jedoch beim Perforieren den Nachteil, dass es infolge seiner Weichheit keine optimale Perforation gestattet und die Durchlaufgeschwindigkeit des ganzen Druckwerkes und eventuell weiterer angeschlossener Druckwerke begrenzt. Ausserdem werden die Bögen durch das Gummituch beim Perforieren verformt, so dass nachher kein ganzer Stapel mehr aufgeschichtet werden kann. Dasselbe gilt sinngemäss beim Stanzen, d.h. das Gummituch ist dazu zu nachgiebig.In offset sheetfed presses, the blanket cylinder that works with the impression cylinder - also known as the impression cylinder - is provided with a blanket and stands at a defined pressure against the impression cylinder. To create perforations, the printing cylinder is covered with a perforation band, while the blanket is left unchanged on the blanket cylinder. However, the rubber blanket has the disadvantage that it does not allow optimal perforation due to its softness and limits the throughput speed of the entire printing unit and possibly other connected printing units. In addition, the sheets are deformed by the rubber blanket during perforation, so that an entire stack can no longer be piled up afterwards. The same applies analogously to punching, i.e. the rubber blanket is too compliant.

Es hat sich ausserdem gezeigt, dass für das Durchführen von Perforationen und/oder Stanzungen oft kein Druckwerk frei ist, so dass mit dessen Durchführung zugewartet werden muss. Es ist daher wünschenswert, bei Offset-Bogenmaschinen mit Zusatzeinheiten, beispielsweise Lackierwerke, auf diese auszuweichen und für die Durchführung von Perforationen und/oder Stanzungen zu verwenden.It has also been shown that there is often no free printing unit for performing perforations and / or punching, so that it must be waited for to be carried out. It is therefore desirable in the case of offset sheet-fed machines with additional units, for example coating units, to switch to them and to use them to carry out perforations and / or punchings.

Es ist davon ausgehend Aufgabe der vorliegenden Erfindung eine Gegendruckvorrichtung für die Durchführung von Perforationen und/oder Stanzungen an Offset-Bogenmaschinen anzugeben, die es einerseits gestattet, eine höhere Durchlaufgeschwindigkeit und bessere Perforationen und/oder Stanzungen zu erzielen und anderseits die Möglichkeit bietet, weitere an die Offset-Bogenmaschine angeschlossene Einheiten wie Lackierwerke zu diesem Zwecke zu verwenden.Based on this, it is an object of the present invention to provide a counterpressure device for performing perforations and / or punchings on offset sheet-fed machines Specify which, on the one hand, allows a higher throughput speed and better perforations and / or punchings to be achieved and, on the other hand, offers the possibility of using other units such as coating units connected to the offset sheet machine for this purpose.

Diese Aufgabe wird mit der Gegendruckvorrichtung gemäss Patentanspruch 1 gelöst.This object is achieved with the back pressure device according to claim 1.

Sogenannte Perforationsbleche wurden früher im Buchdruck verwendet, doch wurden diese alten Buchdruckmaschinen durch die Offset-Bogenmaschinen technisch überholt und die dort verwendeten Perforationsbleche durch das Gummituch ersetzt.So-called perforated plates were previously used in letterpress printing, but these old letterpress machines were technically overhauled by offset sheetfed presses and the perforated plates used there were replaced by the rubber blanket.

Vorzugsweise weist die Metallfolie an ihrer Unter- oder Oberseite eine Unter- bzw. Auflage auf, um eine Gesamtdicke zu ergeben, die der entsprechenden Dicke des vorbekannten, üblichen Gummituchs entspricht.The metal foil preferably has a bottom or top surface on its underside or top side in order to give an overall thickness which corresponds to the corresponding thickness of the known, conventional rubber blanket.

Die Erfindung wird im folgenden anhand einer Zeichnung eines Ausführungsbeispiels näher erläutert.

The invention is explained below with reference to a drawing of an embodiment.
Fig. 1
shows schematically an arrangement of a printing and coating unit of an offset sheet machine,
Fig. 2
shows a section through the strip provided with strips according to the invention and
Fig. 3
shows a detail of Fig. 1 on a larger scale.

Fig. 1 zeigt schematisch eines von gegebenenfalls mehreren Druckwerken einer Offset-Bogenmaschine mit einem Plattenzylinder 1, einem Druckzylinder 2 und einem dazwischen angeordneten Gummituchzylinder 3, auf welchem anstatt eines Gummituchs eine Folie 4 aufgespannt ist. Wird das Druckwerk jedoch zum Drucken benutzt, ist auf dem Gummituchzylinder 3 das übliche Gummituch aufgespannt. Für das Perforieren wird auf den Druckzylinder 2 ein Perforationsband 5, siehe Fig. 3, aufgespannt, dessen Zähne in Richtung Gummituchzylinder 3 ausgerichtet sind, um das dazwischen gelangende Papier zu perforieren. Für das Stanzen werden dazu geeignete Mittel aufgebracht.1 schematically shows one of possibly several printing units of an offset sheet-fed machine with a plate cylinder 1, a printing cylinder 2 and a blanket cylinder 3 arranged in between, on which a film 4 is stretched instead of a blanket. Will the printing unit however, used for printing, the usual blanket is stretched on the blanket cylinder 3. For the perforation, a perforation band 5, see FIG. 3, is stretched onto the printing cylinder 2, the teeth of which are aligned in the direction of the blanket cylinder 3, in order to perforate the paper that passes between them. Suitable means are used for punching.

Die Verwendung einer Folie, z.B. aus Chromstahl, als Gegendruckmittel, ergibt nicht nur eine bessere, saubere Perforation oder Stanzung des Papiers sondern ermöglicht vor allem auch, die normale Druckgeschwindigkeit bei Offset-Bogenmaschinen beizubehalten, so dass das Bedrucken und das Perforieren oder Stanzen mit gleicher Geschwindigkeit erfolgen kann. Dies war vorher mit der Verwendung von Gummitüchern nicht möglich, da diese beim Perforieren oder Stanzen keine so hohen Geschwindigkeiten erlauben und somit die Geschwindigkeit bei diesem Arbeitsgang reduziert werden musste.The use of a film, e.g. made of chrome steel, as a counterpressure, not only results in a better, clean perforation or punching of the paper, but above all also enables the normal printing speed to be maintained with offset sheetfed presses, so that printing and perforating or punching can take place at the same speed. This was previously not possible with the use of rubber blankets, since these do not allow such high speeds when perforating or punching, and the speed had to be reduced during this operation.

In Fig. 1 erkennt man ausserdem das Farbwerk 6 mit den verschiedenen Farbwalzen, die die Druckfarbe auf den Plattenzylinder übertragen, sowie das Feuchtwerk 7. Der Papierbogen 8 gelangt von der Zwischentrommel 9 auf eine erste Anlegetrommel 10, von dieser auf den Druckzylinder 2 und anschliessend auf die zweite Anlegetrommel 11, von wo der Bogen gegebenenfalls auf eine weitere Trommel gelangt und, falls vorgesehen, auf ein weiteres Druckwerk oder zu einer Lackiereinheit 19.In Fig. 1 you can also see the inking unit 6 with the different inking rollers, which transfer the printing ink to the plate cylinder, and the dampening unit 7. The paper sheet 8 passes from the intermediate drum 9 to a first feed drum 10, from this to the printing cylinder 2 and then to the second feed drum 11, from where the sheet may reach another drum and, if provided, to another printing unit or to a coating unit 19.

In Fig. 3 sind der Plattenzylinder 1, der Druckzylinder 2 sowie der Gummituchzylinder 3 in vergrössertem Massstab im Querschnitt dargestellt. Der Plattenzylinder 1 mit der darauf aufgespannten Druckplatte 12 ist vorbekannt und je nach Maschinentyp unterschiedlich gebaut. In diesem Ausführungsbeispiel ist auf dem Druckzylinder 2 das Perforationsband 5 befestigt, wie dies bei vorbekannten Druckwerken bekannt ist. Dabei kann das Perforationsband längs oder quergespannt sein. Der Gummituchzylinder 3 ist erfindungsgemäss mit der Folie 4 bespannt, falls eine Perforation durchgeführt werden soll.In Fig. 3, the plate cylinder 1, the impression cylinder 2 and the blanket cylinder 3 are shown on an enlarged scale in cross section. The plate cylinder 1 with the printing plate 12 clamped thereon is previously known and is constructed differently depending on the type of machine. In this embodiment, this is on the impression cylinder 2 Perforation tape 5 attached, as is known in prior art printing units. The perforation band can be longitudinal or cross-stretched. The blanket cylinder 3 is covered with the film 4 according to the invention if a perforation is to be carried out.

Falls die Lackiereinheit 19 für die Perforation und/oder Stanzung verwendet werden soll, wird auf dem einen Zylinder, der Formzylinder 17, die Folie 4 befestigt und auf dem anderen Zylinder, der Druckzylinder 18, das Perforationsband oder die Stanzmittel aufgebracht, wobei beide Zylinder 17 und 18 die gleiche oder ähnliche Aufspann-Einrichtung 16 mit Schiene 13 wie die vorgenannten Zylinder aufweisen. Beim Lackierwerk 19 sind ferner die Dosierwalze 20 und die Lackauftragwalze 21 eingezeichnet, die beim Perforieren oder Stanzen selbstverständlich nicht im Eingriff mit dem Formzylinder 17 stehen. Unter der Dosier- und Lackauftragwalze ist eine Lackauffangwanne angedeutet.If the coating unit 19 is to be used for the perforation and / or punching, the forme cylinder 17, the film 4 is attached to one cylinder and the printing cylinder 18, the perforation band or the punching means is applied to the other cylinder, both cylinders 17 and 18 have the same or similar clamping device 16 with rail 13 as the aforementioned cylinders. In the coating unit 19, the metering roller 20 and the coating roller 21 are also shown, which of course are not in engagement with the forme cylinder 17 when perforating or punching. A paint collecting tray is indicated under the metering and paint application roller.

Die Folie 4 gemäss Fig. 2 ist in zwei gegenüber liegenden Leisten 13 gefasst, die mit der Folie verklebt und/oder vernietet sind. Falls keine Perforationen oder Stanzungen durchzuführen sind, wird auf dem Gummituchzylinder 3 ein übliches Gummituch aufgespannt, und das Perforationsband 5 selbstverständlich weggenommen. Der Aufzug des Gummituchzylinders weist eine genormte, dem Druckerzeugnis angepasste Dicke auf, so dass eine bestimmte Druckbeistellung zwischen dem Gummituchzylinder und dem damit kooperierenden Druckzylinder vorhanden ist, so dass die anstelle des Gummituchs tretende Folie, unter Berücksichtigung des Perforationsbandes oder Stanzbleches, die gleiche Dicke aufweisen muss. Dasselbe gilt sinngemäss für das Lackierwerk.The film 4 according to FIG. 2 is held in two opposite strips 13 which are glued and / or riveted to the film. If no perforations or punchings are to be made, a conventional rubber blanket is stretched on the blanket cylinder 3, and the perforation band 5 is of course removed. The elevator of the rubber blanket cylinder has a standardized thickness that is adapted to the printed product, so that a certain amount of pressure is provided between the rubber blanket cylinder and the printing cylinder cooperating with it, so that the film replacing the rubber blanket has the same thickness, taking into account the perforation band or punched sheet got to. The same applies analogously to the coating unit.

Da eine so dicke Folie nicht erforderlich ist und sich überdies nur schwer auf den Zylinder spannen lässt, wird eine dünne Folie von beispielsweise 0,3 mm verwendet und eine Unterlage 15 von 1,65 mm unter die Folie angebracht, um eine Normdicke von 1,95 mm zu erzielen. Dabei kann diese Unterlage je nach Verwendung eine unterschiedliche Steifigkeit aufweisen und z. B. eine Pressspanplatte sein. Vorzugsweise wird die Unterlage nur einseitig befestigt, wie dies durch die längere Niete 14 symbolisiert ist, kann jedoch auch an beiden Seiten befestigt werden oder nur an der Folie angebracht sein.Since such a thick film is not required and, moreover, it is difficult to clamp onto the cylinder, a thin film of, for example, 0.3 mm is used and a base 15 of 1.65 mm is attached under the film in order to achieve a standard thickness of 1. To achieve 95 mm. This pad can have a different stiffness depending on the use and z. B. be a particle board. The base is preferably only attached on one side, as symbolized by the longer rivets 14, but can also be attached on both sides or only attached to the film.

Zum Schonen der Folie kann es sich als zweckmässig erweisen, eine relativ harte Folie, beispielsweise aus Kunststoff, darauf zu spannen, die bei Bedarf durch eine neue Folie ersetzt werden kann. Selbstverständlich muss die Gesamtdicke dieselbe sein wie diejenige des für den bestimmten Einsatz entsprechenden, üblichen Gummituchs.To protect the film, it may prove expedient to stretch a relatively hard film, for example made of plastic, onto it, which can be replaced by a new film if necessary. Of course, the total thickness must be the same as that of the usual rubber blanket for the specific application.

Die Schienen 13 sind die gleichen wie diejenigen, die für das Gummituch verwendet werden, so dass die Aufspann-Einrichtung 16 auf dem Gummituchzylinder dieselbe oder eine ähnliche wie die vorbekannte bleibt, so dass bei der Verwendung der Folie für das Perforieren mitsamt der eventuellen Unter- und/oder Auflage anstatt des für diesen bestimmten Einsatz üblichen Gummituchs keine Aenderungen am Druckwerk oder Lackiereinheit vorgenommen werden müssen.The rails 13 are the same as those used for the rubber blanket, so that the clamping device 16 on the rubber blanket cylinder remains the same or similar to the previously known one, so that when the film is used for perforating together with the possible underside, and / or edition no changes to the printing unit or coating unit need to be made instead of the rubber blanket customary for this particular application.

Als Material für die Folie 4 kann Metall, z.B. Chromstahl, oder auch ein anderes geeignetes Metall oder ein geeigneter Kunststoff verwendet werden.Metal, e.g. Chrome steel, or another suitable metal or a suitable plastic can be used.

Es ist noch darauf hinzuweisen, dass ausser den bereits genannten Vorteilen, ein weiterer Vorteil darin besteht, dass bei der Perforation oder Stanzung mit der Folie die Bögen nicht verformt werden, so dass der gesamte Stapel wie vor der Bearbeitung gestapelt werden kann und dessen Wegtransport damit erheblich erleichtert wird, im Gegensatz zu den stark verformten Bögen nach der Perforation mittels Gummituchbezug. Dadurch ist es auch möglich, die Folie, oft auch Perforationsblech genannt, für das Stanzen verschiedenster Muster, z. B. von Adressfeldern und dergleichen zu verwenden.It should also be pointed out that in addition to the advantages already mentioned, another advantage is that the sheets are not deformed when perforating or punching with the film, so that the entire stack is like can be stacked before processing and its transport is thus made considerably easier, in contrast to the strongly deformed sheets after perforation with a rubber blanket cover. This also makes it possible to use the film, often also called perforation sheet, for punching a wide variety of patterns, e.g. B. use of address fields and the like.
