Definitions
- the invention relates to a sheet-fed offset printing machine according to the five-cylinder system, with a counter-pressure cylinder taking over the sheets to be printed from an investor, to which, viewed in the transport direction of the sheets, two offset rubber cylinders, each working with a plate cylinder, are placed one behind the other, the counter-pressure cylinder has twice the circumference, based on the circumference of the rubber cylinders.
- a machine of this type is known from the specialist book "Introduction to offset printing " by Wolfgang Walenski, Eggen specialist book series, page 113. With this machine, a sheet can be printed on one side with double face printing. A reversing device would be required for reverse printing.
- page 155 of the same specialist book shows a sheet-fed offset printing machine for face and reverse printing, in which a sheet to be printed is passed between two blanket cylinders, with one blanket carrying a gripper system worked.
- the object of the invention is to further develop a printing press of the first-mentioned type in such a way that a sheet fed into the machine can be provided with triple face printing and an additional back pressure with little additional space.
- a major advantage of the sheet-fed offset rotary printing press is that it is also possible to apply a double perfecting and an impression if two sheets are placed on the double-sized impression cylinder during each revolution.
- Fig. 1 shows a printing unit 1, which comprises a so-called double-sized impression cylinder 2, on which two printing plates 3 and 4 are attached.
- An inking and dampening unit 5, 6 is arranged below the impression cylinder 2 for inking the printing plates 3, 4.
- An offset rubber cylinder 7, to which a plate cylinder 8 is assigned, is employed on the impression cylinder. Seen in the transport direction of the sheets to be printed, a further offset rubber cylinder 9 is placed behind the blanket cylinder 7 on the impression cylinder 2, to which a plate cylinder 10 is assigned.
- a sheet 11 coming from a conventional sheet system is picked up by a conventional gripper system (not shown in more detail), which is arranged, for example, in front of the printing plate 4, and is guided past the two rubber cylinders 7, 9, after which the sheet is passed to another printing unit or to the sheet transfer point 12 Sheet delivery, for example via a chain system, is supplied.
- the previously colored printing image on an offset plate 3, which is mounted in mirror image with respect to a DiLitho plate 4, on the impression cylinder 2 was advantageously transferred to the rubber cylinder 7, since no sheet is fed to the printing unit 1 while the printing plate 3 runs past the blanket cylinder 7.
- the illustration according to FIG. 2 shows that a sheet 11 can be gripped by the gripper system assigned to the pressure plate 4 and can be provided with a double front printing by the rubber cylinder 7 and with a back pressure by the printing plate 4.
- a further imprint takes place through the rubber cylinder 9, so that the sheet at the sheet transfer point 12 is provided with a triple face print and an impression.
- the main advantage of the printing machine comes into play according to the invention if only one sheet is applied during each revolution of the impression cylinder 2, so that a second print image is produced by one plate, for example plate 3, which in this case acts as an offset printing plate the blanket cylinder 7 can be transferred.
- the aforementioned triple face printing (offset) plus a backprint (DiLitho) is possible without the printing unit becoming significantly more voluminous.

Description
Die Erfindung betrifft eine Bogen-Offsetrotationsdruckmaschine nach dem Fünfzylinder-System, mit einem die zu bedruckenden Bogen von einem Anleger übernehmenden Gegendruckzylinder, an den, in Transportrichtung der Bogen gesehen, hintereinander zwei mit jeweils einem Plattenzylinder zusammenarbeitende Offset-Gummizylinder angestellt sind, wobei der Gegendruckzylinder den doppelten Umfang, bezogen auf den Umfang der Gummizylinder, aufweist.The invention relates to a sheet-fed offset printing machine according to the five-cylinder system, with a counter-pressure cylinder taking over the sheets to be printed from an investor, to which, viewed in the transport direction of the sheets, two offset rubber cylinders, each working with a plate cylinder, are placed one behind the other, the counter-pressure cylinder has twice the circumference, based on the circumference of the rubber cylinders.
Eine Maschine dieser Art ist aus dem Fachbuch «Einführung in den Offsetdruck" von Wolfgang Walenski, Eggen-Fachbuchreihe, Seite 113, bekannt. Mit dieser Maschine kann ein Bogen auf einer Seite mit einem zweifachen Schöndruck bedruckt werden. Für Widerdruck wäre eine Wendevorrichtung erforderlich. Darüber hinaus zeigt die Seite 155 des gleichen Fachbuches eine Bogen-Offsetdruckmaschine für Schön- und Widerdruck, bei dem ein zu bedruckender Bogen zwischen zwei Gummizylindern hindurchgeführt wird, wobei ein Gummizylinder ein Greifersystem trägt. Hier wird also im sogenannten «Blanked to Blanket»-Druckbetrieb gearbeitet.A machine of this type is known from the specialist book "Introduction to offset printing " by Wolfgang Walenski, Eggen specialist book series, page 113. With this machine, a sheet can be printed on one side with double face printing. A reversing device would be required for reverse printing. In addition, page 155 of the same specialist book shows a sheet-fed offset printing machine for face and reverse printing, in which a sheet to be printed is passed between two blanket cylinders, with one blanket carrying a gripper system worked.
Aufgabe der Erfindung ist es, eine Druckmaschine der erstgenannten Art so weiterzubilden, dass mit einem geringen Aufwand an zusätzlichem Raum ein in die Maschine geführter Bogen mit dreifachem Schöndruck und einem zusätzlichen Widerdruck versehen werden kann.The object of the invention is to further develop a printing press of the first-mentioned type in such a way that a sheet fed into the machine can be provided with triple face printing and an additional back pressure with little additional space.
Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Patentanspruchs gelöst.This object is achieved by applying the features of the characterizing part of the patent claim.
Ein wesentlicher Vorteil der Bogen-Offsetrotationsdruckmaschine liegt darin, dass auch die Aufbringung eines zweifachen Schön- und eines Widerdruckes möglich ist, wenn während einer jeden Umdrehung des doppelt grossen Gegendruckzylinders zwei Bogen an diesen angelegt werden.A major advantage of the sheet-fed offset rotary printing press is that it is also possible to apply a double perfecting and an impression if two sheets are placed on the double-sized impression cylinder during each revolution.
Im folgenden wird die erfindungsgemässe Bogen-Offsetrotationsdruckmaschine anhand von Ausführungsbeispielen beschrieben, wobei Bezug auf die beiliegende Zeichnung genommen wird. In dieser zeigen:The sheet-fed offset rotary printing press according to the invention is described below using exemplary embodiments, reference being made to the accompanying drawing. In this show:
Fig. 1 und 2 in schematischer Darstellung die erfindungsgemässe Bogen-Offsetrotationsdruckmaschine.1 and 2 in a schematic representation of the sheet-fed offset printing press according to the invention.
Fig. 1 zeigt ein Druckwerk 1, das einen sogenannten doppelt grossen Gegendruckzylinder 2 umfasst, auf dem zwei Druckplatten 3 und 4 befestigt sind. Unterhalb des Gegendruckzylinders 2 ist für die Einfärbung der Druckplatten 3, 4 ein Farb- und Feuchtwerk 5, 6 angeordnet. An den Gegendruckzylinder ist ein Offset-Gummizylinder 7 angestellt, dem ein Plattenzylinder 8 zugeordnet ist. In Transportrichtung der zu bedruckenden Bogen gesehen, ist hinter dem Gummizylinder 7 ein weiterer Offset-Gummizylinder 9 an den Gegendruckzylinder 2 angestellt, dem ein Plattenzylinder 10 zugeordnet ist.Fig. 1 shows a
Ein von einer üblichen Bogenanlage kommender Bogen 11 wird durch ein herkömmliches, nicht näher dargestelltes Greifersystem, das beispielsweise vor der Druckplatte 4 angeordnet ist, erfasst und an den beiden Gummizylindern 7, 9 vorbeigeführt, wonach an der Bogenübergabestelle 12 der Bogen einem weiteren Druckwerk oder einem Bogenausleger, beispielsweise über ein Kettensystem, zugeführt wird.A
Bei der in Fig. 1 gezeigten Winkelstellung des Gegendruckzylinders 2 wurde das auf einer Offset-Platte 3, die spiegelbildlich gegenüber einer DiLitho-Platte 4, auf dem Gegendruckzylinder 2 montiert ist, befindliche, zuvor eingefärbte Druckbild in vorteilhafter Weise auf den Gummizylinder 7 übertragen, da während des Vorbeilaufens der Druckplatte 3 an dem Gummizylinder 7 kein Bogen dem Druckwerk 1 zugeführt wird. Somit wird der Gummizylinder 7 zum einen von dem Plattenzylinder 8 her und zum anderen von der Offsetplatte 3 her, d. h. zweifach eingefärbt. Die Darstellung gemäss Fig. 2 lässt erkennen, dass ein Bogen 11 von dem der Druckplatte 4 zugeordneten Greifersystem erfasst und zum einen vom Gummizylinder 7 mit einem zweifachen Schöndruck und von der Druckplatte 4 mit einem Widerdruck versehen werden kann. Bei einer weiteren Drehung des Gegendruckzylinders 2 erfolgt dann ein weiterer Aufdruck durch den Gummizylinder 9, so dass der Bogen an der Bogenübergabestelle 12 insgesamt mit dreifachem Schöndruck und einem Widerdruck versehen ist.In the angular position of the
Mit dieser Druckmaschine ist es des weiteren in vorteilhafter Weise möglich, einen durch die Maschine zu führenden Bogen mit zweifachem Schöndruck mittels der Gummizylinder 7 und 9 sowie mit einem Widerdruck mittels zwei DiLitho-Platten 3 und 4 zu versehen, wenn bei einer jeden Umdrehung des Gegendruckzylinders 2 zwei Bogen zugeführt werden.With this printing machine, it is also advantageously possible to provide a sheet to be fed through the machine with double face printing by means of the rubber cylinders 7 and 9 and with a back pressure by means of two DiLitho plates 3 and 4, if with each revolution of the
Der Hauptvorteil der Druckmaschine kommt jedoch dann erfindungsgemäss zum Tragen, wenn nur ein Bogen während einer jeden Umdrehung des Gegendruckzylinders 2 angelegt wird, so dass jeweils durch eine Platte, beispielsweise durch die Platte 3, die in diesem Fall als Offsetdruckplatte wirkt, ein zweites Druckbild auf den Gummizylinder 7 übertragen werden kann. In diesem Fall ist der eingangs erwähnte dreifache Schöndruck (Offset) plus einem Widerdruck (DiLitho) möglich, ohne dass das Druckwerk wesentlich voluminöser wird.The main advantage of the printing machine, however, comes into play according to the invention if only one sheet is applied during each revolution of the
