Definitions
- the invention relates to a device for feeding and changing printing forms on the printing form cylinder of printing presses, in which the printing form cylinder in a cylinder pit has a holding device assigned to the beginning of the printing, which has a detection area for receiving the front edge of the printing plate in the form of a detection area that extends over the Provides format-wide gap.
- EP 0 567 754 A1 discloses an apparatus for feeding a printing plate to a plate cylinder of a printing press.
- At least one easily rotatable roller serves as an element for holding and guiding a printing plate, the side of the roller facing the printing unit in a plate changing position essentially lying on a straight line which runs parallel to the clamping surfaces of the device for receiving the printing plate front edge and runs obliquely between these clamping surfaces up out leads out to the printing unit.
- a suction cup can also be arranged on this straight line as a further element for holding and guiding the pressure plate. The suction cup can be vented by providing a hole in the rear area of the pressure plate.
- EP 0 570 702 A1 relates to a device for feeding printing plates onto the plate cylinder of printing machines, in particular sheet-fed offset printing machines.
- an insertion rail that extends over the format width can be adjusted on the outer circumference of the plate cylinder in the area of the print start in such a way that the front edge of the pressure plate can be inserted directly into the detection area of the print start clamping rail via the insertion surface formed by the insertion rail.
- the outer circumference of the plate cylinder thus forms a funnel-shaped area for the leading edge of the printing plate with the insertion rail. All components guiding or supporting the pressure plate during the insertion are arranged in front of the plate cylinder, which limits its accessibility.
- the invention has for its object to improve a printing form changing device so that on the one hand the handling of the printing forms on the changing device itself is simplified and the accessibility to the printing unit is maintained.
- the space in front of the printing unit cylinders is in the Operation, so accessible when changing non-disk, so that there are no impairments for the printer.
- the printing plates can be removed from the magazine both through side openings and from above, the printing plate magazine takes these ergonomic features into account to a high degree.
- the pivotable holding element to be provided with a projection which in the horizontal position of the holding element reaches the surface of the printing form cylinder.
- the holding element which can be pivoted about an axis, has upper and lower receiving elements which, in the exemplary embodiment shown, are designed as suction plates subjected to negative pressure.
- the holding element is arranged above a magazine which is divided by a partition.
- the dividing wall dividing the magazine into a front and rear chamber is provided in its upper region with a strong curvature which improves the positioning of the printing plate to be newly fed to the surface of the printing form cylinder.
- the rear chamber is arranged somewhat higher than the front chamber of the magazine in order to both make it easier to grasp the new printing form to be fed by the pivoting holding element and to simplify the handling of the plates for the printer.
- the projection of the pivotable holding element forms in its horizontal position with a guide on the magazine an inlet gap into which the rear part of the printing form to be removed from the cylinder is inserted and temporarily fixed there by receiving means provided on the underside of the holding element.
- FIG. 1 shows the side view of a printing form changing device with a printing form to be applied provided in a chamber of a magazine.
- a printing unit lying below the printing material web comprises a transfer cylinder 110 and a printing form cylinder 101, on which a first printing form 111 is applied.
- a protective device 108 is assigned to the pair of cylinders 101 and 110 and can be actuated via an actuating unit 117.
- the printing form cylinder 101 is assigned a pressure element 107, which is provided by a by means of an actuating unit 115, lever 116 moved to the surface of the printing form cylinder 101 and can be removed therefrom.
- the printing form cylinder 101 receives the front and the rear folded end of the printing form 111 in a channel 114, in which a holding device 113 is located. This is shown only schematically in FIG. 1 and is not the subject of the present invention.
- a pair of printing formes 102 and a pivotable holding element 103 are assigned to the pair of cylinders 101, 110.
- the pivotable holding element 103 comprises a projection 109 which, when set against the surface of the plate cylinder 101, engages over a lower guide 104 of the printing form magazine 102 and in this position forms an inlet gap for a printing form 111 to be removed from the printing form cylinder 101.
- the pivotable holding element 103 can be moved about a pivot axis 119 by means of an actuating unit 118 and is provided with upper and lower receiving elements 105 and 106.
- a hydraulic unit can also function as the actuating unit 118; an electromotive actuator would also be conceivable.
- suction plates acted upon by vacuum act as receiving elements 105 and 106.
- Magnetic devices or the printing form 111 and 112 form-fittingly fixing receiving elements would also be conceivable.
- the printing form magazine 102 comprises two chambers 123 and 124. These are separated from one another by a partition 122, the bottom of the rear chamber 124 being arranged somewhat higher than that of the front chamber 123. As a result, the printing forms 112 to be applied in the magazine 102 are so high that that they are the top Receiving elements 105 of the pivotable holding element 103 lie opposite each other in its vertical position and the second printing form 112 can be easily gripped by the latter.
- the partition 122 has a strong curvature 125 in the upper region, which on the one hand forms the inlet gap for a printing form 111 to be removed from the printing form cylinder 101 and on the other hand supports the positioning of the printing form 112 to be applied to the surface of the plate cylinder 101.
- Fig. 2 shows a holding element pivoted into its operating position.
- the two cylinders 101 and 110 slowly rotate backwards, the protective device 108 being pivoted away from the gap between the cylinder surfaces.
- the pivotable holding element 103 swings into a position parallel to the guide 104 and uses it to define an inlet gap.
- the pressing element 107 is now placed on the surface of the printing form 111 to be removed.
- Fig. 3 the release of a rear printing form end is shown.
- the holding device 113 in the channel 114 of the printing form cylinder 101 releases the rear end of the printing form 111 to be removed. Due to the inherent elasticity of the printing form 111, the end of the printing form 111 extends from the channel 114 and strikes the projection 109 of the pivotable holding element 103. The slow backward movement of the printing form cylinder 101 causes the rear part of the printing form 111 to be removed from the printing form cylinder 101 to enter the front chamber 123 into the inlet channel formed by the projection 109 and the guide 104.
- the projection 109 is characterized by the inherent rigidity of the Printing form 111 resulting curvature of the printing form 111 held so that the printing form 111 does not contact the surface of the transfer cylinder 110 during removal from the printing form cylinder 101.
- FIG. 4 shows the state in which the first printing forme 111 has already largely been moved into the front chamber 123.
- the lower receiving element 106 is activated, which brakes the printing form 111 to be removed from the cylinder 101. Since the first printing form 111 is now fixed by the lower receiving element 106, the holding device 113 also releases the front edge 120 of the printing form 111. Due to the elasticity of the first printing form 111, the front edge 120 now also extends from the channel 114; the first printing form 111 is now held only by the lower receiving element 105.
- the cylinder continues its backward rotation, whereby - thanks to the positioning of the first printing form 111 on its surface and the resulting rolling contact - the printing form 111 is pushed further into the front chamber 123.
- the receiving element 106 now releases the first printing form 111; the pivotable holding element 103 pivots upward to the second printing form 112, which is now to be applied.
- the released, first printing form 111 now moves, due to gravity, into the front chamber 123 of the printing form magazine 102.
- the rotation of the cylinder 101 is stopped and the upper receiving elements 105 fix the second printing form 112 in the rear, somewhat higher-lying chamber 124 of the printing form magazine 102. Since this second printing form 112 has to be bent to convey to the surface of the printing form cylinder 101, there are two receiving elements 105 provided on the pivotable holding element 103. The one so fixed Printing form 112 is now made by swiveling the holding element 103 to the surface of the printing form cylinder 101.
- the front edge 120 of the printing form 112 is set against the surface of the printing form cylinder 101 by pivoting the holding element 103.
- the pressure element 107 is turned off by the cylinder 101, the printing form cylinder 101 rotates slowly forward.
- the front edge 120 of the second printing form 112 springs into the holding device 113, as a result of which the second printing form 112 is slowly drawn onto the circumference of the printing form cylinder 101.
- the upper receiving elements 105 remain activated during the opening of the second printing form 112. If these are, for example, suction plates subjected to negative pressure, the negative pressure is present until the second printing form 112 is largely guided around the printing form cylinder 101.
- the rear edge 121 has approached the upper receiving elements 105, the pressing element 107 - here embodied as a roller, which is mounted on a lever 116 - is placed against the printing plate 112 to be newly applied.
- the second printing form 112 is released by the upper receiving elements 105, as a result of which the rear end of the second printing form 112 springs upward away from the pivotable holding element 103.
- the printing form cylinder 101 completes one revolution.
- the channel 114 together with the holding device 113 lies opposite the pressing element 107.
- the pressing element 107 supports the pressure form 112 nestling against the surface of the printing form cylinder 101.
- the second Printing form 112 is, as it were, ironed on before its rear edge 121 is clamped.
- the pivotable holding element 103 pivots back into its vertical position, the removed printing form 111 can now be removed from the magazine 102.
- the protective device 108 is also pivoted back into the gap between the transfer cylinder 110 and the printing form cylinder 101.

Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Zuführen und Wechseln von Druckformen auf den Druckformzylinder von Druckmaschinen, bei welcher der Druckformzylinder in einer Zylindergrube eine dem Druckanfang zugeordnete Haltevorrichtung aufweist, die zur Aufnahme der Vorderkante der Druckplatte einen zu öffnenden Erfassungsbereich in Form eines sich über die Formatbreite erstreckenden Spaltes vorsieht.The invention relates to a device for feeding and changing printing forms on the printing form cylinder of printing presses, in which the printing form cylinder in a cylinder pit has a holding device assigned to the beginning of the printing, which has a detection area for receiving the front edge of the printing plate in the form of a detection area that extends over the Provides format-wide gap.
Aus dem Stande der Technik, EP 0 431 364 A2, ist eine Handhabungsvorrichtung zur Beschickung von Plattenzylindern an Rollenrotationsmaschinen bekannt geworden. An einer Führung ist ein vertikal bewegbarer und schwenkbar angebrachter Roboterarm vorgesehen, der durch wenigstens ein Gelenk in Armabschnitte gegliedert ist und der an dem von der Führung am weitesten entfernten Armabschnitt einen Handhabungskopf aufweist. Mittels dieser Vorrichtung ist die Druckformentnahme an höher gelegenen Druckwerken von Rotationsdruckmaschinen in Turmbauweise möglich.From the prior art, EP 0 431 364 A2, a handling device for loading plate cylinders on roller rotating machines has become known. Provided on a guide is a vertically movable and pivotably mounted robot arm which is divided into arm sections by at least one joint and which has a handling head on the arm section furthest from the guide. With this device, the printing form removal at higher lying printing units of rotary printing presses in tower construction is possible.
EP 0 567 754 A1 offenbart einen Vorrichtung zum Zuführen einer Druckplatte zu einem Plattenzylinder einer Druckmaschine. Als Element zum Halten und Führen einer Druckplatte dient mindestens eine leicht drehbare Rolle, wobei die druckwerkzugewandte Seite der Rolle in einer Plattenwechselposition im wesentlichen auf einer Geraden liegt, welche parallel zu den Klemmflächen der Einrichtung zur Aufnahme der Druckplattenvorderkante verlaufend zwischen diesen Klemmflächen hindurchführt und schräg nach oben aus dem Druckwerk herausführt. Auf dieser Geraden kann zudem als weiteres Element zum Halten und Führen der Druckplatte ein Saugnapf angeordnet werden, der dadurch entlüftbar ist, daß eine Bohrung im hinteren Bereich der Druckplatte vorgesehen ist.EP 0 567 754 A1 discloses an apparatus for feeding a printing plate to a plate cylinder of a printing press. At least one easily rotatable roller serves as an element for holding and guiding a printing plate, the side of the roller facing the printing unit in a plate changing position essentially lying on a straight line which runs parallel to the clamping surfaces of the device for receiving the printing plate front edge and runs obliquely between these clamping surfaces up out leads out to the printing unit. A suction cup can also be arranged on this straight line as a further element for holding and guiding the pressure plate. The suction cup can be vented by providing a hole in the rear area of the pressure plate.
EP 0 570 702 A1 bezieht sich auf eine Vorrichtung zum Zuführen von Druckplatten auf den Plattenzylinder von Druckmaschinen, insbesondere Bogenoffsetdruckmaschinen. An den in eine bestimmte Winkelposition verfahrbaren Plattenzylinder ist eine sich über die Formatbreite erstreckende Einführschiene derartig an den Außenumfang des Plattenzylinder im Bereich des Druckanfangs anstellbar, daß die Vorderkante der Druckplatte über die durch die Einführschiene gebildete Einführfläche direkt in den Erfassungsbereich der Druckanfangspannschiene eingeführt werden kann. Der Außenumfang des Plattenzylinders bildet somit mit der Einführschiene einen trichterförmigen Bereich für die Druckplattenvorderkante. Alle die Druckplatte während der Einführung führenden bzw. abstützenden Komponenten sind vor dem Plattenzylinder angeordnet, was dessen Zugänglichkeit einschränkt.EP 0 570 702 A1 relates to a device for feeding printing plates onto the plate cylinder of printing machines, in particular sheet-fed offset printing machines. On the plate cylinder, which can be moved into a certain angular position, an insertion rail that extends over the format width can be adjusted on the outer circumference of the plate cylinder in the area of the print start in such a way that the front edge of the pressure plate can be inserted directly into the detection area of the print start clamping rail via the insertion surface formed by the insertion rail. The outer circumference of the plate cylinder thus forms a funnel-shaped area for the leading edge of the printing plate with the insertion rail. All components guiding or supporting the pressure plate during the insertion are arranged in front of the plate cylinder, which limits its accessibility.
Der Erfindung liegt die Aufgabe zugrunde, eine Druckformwechseleinrichtung so zu verbessern, daß einerseits die Handhabung der Druckformen an der Wechseleinrichtung selbst vereinfacht und die Zugänglichkeit zum Druckwerk erhalten bleibt.The invention has for its object to improve a printing form changing device so that on the one hand the handling of the printing forms on the changing device itself is simplified and the accessibility to the printing unit is maintained.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the features of patent claim 1.
Da lediglich ein verschwenkbares Halteelement sowohl zur Abnahme der auf dem Druckformzylinder befindlichen Druckform als auch zur Zuführung der neu aufzubringenden Druckform vorgesehen ist, ist der Raum vor den Druckwerkzylindern im Betrieb, also bei Nicht-Platten-Wechsel zugänglich, so daß keinerlei Beeinträchtigungen für den Drucker gegeben sind. Die Entnahme der Druckformen aus dem Magazin kann sowohl durch seitliche Öffnungen als auch von oben erfolgen, das Druckformmagazin trägt diesen ergonomischen Erleichterungen in hohem Maße Rechnung.Since only a pivotable holding element is provided both for removing the printing form located on the printing form cylinder and for feeding the new printing form to be applied, the space in front of the printing unit cylinders is in the Operation, so accessible when changing non-disk, so that there are no impairments for the printer. The printing plates can be removed from the magazine both through side openings and from above, the printing plate magazine takes these ergonomic features into account to a high degree.
Weitere Ausgestaltungen der erfindungsgemäßen Einrichtung sehen vor, das schwenkbare Halteelement mit einem Vorsprung auszustatten, der in horizontaler Lage des Halteelementes an die Oberfläche des Druckformzylinders heranreicht. Das um eine Achse schwenkbare Halteelement verfügt über obere und untere Aufnahmeelemente, die im dargestellten Ausführungsbeispiel als unterdruckbeaufschlagte Saugteller ausgeführt sind. Das Halteelement ist oberhalb eines Magazins angeordnet, welches durch eine Trennwand geteilt ist. Die das Magazin in eine vordere und hintere Kammer teilende Trennwand ist in ihrem oberen Bereich mit einer starken Krümmung versehen, die die Anstellung der jeweils neu zuzuführenden Druckplatte an die Oberfläche des Druckformzylinders verbessert. Die hintere Kammer ist etwas höher als die vordere Kammer des Magazines angeordnet, um sowohl ein leichteres Ergreifen der neu zuzuführenden Druckform durch das schwenkbare Halteelement zu erzielen als auch dem Drucker die Handhabung der Platten zu vereinfachen. Der Vorsprung des schwenkbaren Halteelementes bildet in dessen horizontaler Lage mit einer Führung am Magazin einen Einlaufspalt, in welchen der rückwärtige Teil der vom Zylinder abzunehmenden Druckform eingeführt und dort von an der Unterseite des Halteelementes vorgesehenen Aufnahmemitteln temporär fixiert wird.Further refinements of the device according to the invention provide for the pivotable holding element to be provided with a projection which in the horizontal position of the holding element reaches the surface of the printing form cylinder. The holding element, which can be pivoted about an axis, has upper and lower receiving elements which, in the exemplary embodiment shown, are designed as suction plates subjected to negative pressure. The holding element is arranged above a magazine which is divided by a partition. The dividing wall dividing the magazine into a front and rear chamber is provided in its upper region with a strong curvature which improves the positioning of the printing plate to be newly fed to the surface of the printing form cylinder. The rear chamber is arranged somewhat higher than the front chamber of the magazine in order to both make it easier to grasp the new printing form to be fed by the pivoting holding element and to simplify the handling of the plates for the printer. The projection of the pivotable holding element forms in its horizontal position with a guide on the magazine an inlet gap into which the rear part of the printing form to be removed from the cylinder is inserted and temporarily fixed there by receiving means provided on the underside of the holding element.

In Fig. 1 ist die Seitenansicht einer Druckformwechseleinrichtung mit einer in einer Kammer eines Magazins vorgesehenen aufzubringenden Druckform dargestellt.1 shows the side view of a printing form changing device with a printing form to be applied provided in a chamber of a magazine.
Ein unterhalb der Bedruckstoffbahn liegendes Druckwerk umfaßt einen Übertragungszylinder 110 sowie einen Druckformzylinder 101, auf welchem eine erste Druckform 111 aufgebracht ist. Dem Zylinderpaar 101 und 110 ist eine Schutzvorrichtung 108 zugeordnet, die über eine Stelleinheit 117 betätigbar ist. Dem Druckformzylinder 101 ist ein Andruckelement 107 zugeordnet, welches von einem mittels einer Stelleinheit 115 bewegten Hebel 116 an die Oberfläche des Druckformzylinders 101 an- und von dieser wieder abstellbar ist.A printing unit lying below the printing material web comprises a
Der Druckformzylinder 101 nimmt jeweils das vordere und das hintere abgekantete Ende der Druckform 111 in einem Kanal 114 auf, in welchem sich eine Haltevorrichtung 113 befindet. Diese ist in Fig. 1 lediglich schematisch dargestellt und nicht Gegenstand der vorliegenden Erfindung.The
Dem Zylinderpaar 101, 110 ist ein Druckformmagazin 102 sowie ein verschwenkbares Halteelement 103 zugeordnet. Das verschwenkbare Halteelement 103 umfaßt einen Vorsprung 109, der im an die Oberfläche des Plattenzylinders 101 angestellten Zustand eine untere Führung 104 des Druckformmagazins 102 übergreift und in dieser Lage einen Einlaufspalt für eine vom Druckformzylinder 101 abzunehmende Druckform 111 bildet.A pair of
Das schwenkbare Halteelement 103 ist mittels einer Stelleinheit 118 um eine Schwenkachse 119 bewegbar und mit oberen und unteren Aufnahmeelementen 105 bzw. 106 versehen. Als Stelleinheit 118 kann neben einer Pneumatik auch eine Hydraulik fungieren; ebensogut wäre auch ein elektromotorischer Stellantrieb denkbar. Als Aufnahmeelement 105 und 106 fungieren im dargestellten Ausführungsbeispiel unterdruckbeaufschlagte Saugteller. Auch magnetische Einrichtungen oder die Druckform 111 und 112 formschlüssig fixierende Aufnahmeelemente wären denkbar.The
Das Druckformmagazin 102 umfaßt zwei Kammern 123 und 124. Diese sind durch eine Trennwand 122 voneinander getrennt, wobei der Boden der hinteren Kammer 124 etwas höher angeordnet ist als der der vorderen Kammer 123. Dadurch stehen die jeweils aufzubringenden Druckformen 112 im Magazins 102 so hoch, daß sie den oberen Aufnahmeelementen 105 des schwenkbaren Halteelementes 103 in dessen senkrechter Lage gegenüberliegen und ein leichtes Ergreifen der zweiten Druckform 112 durch diese möglich ist. Die Trennwand 122 weist im oberen Bereich eine starke Krümmung 125 auf, welche zum einen den Einlaufspalt für eine vom Druckformzylinder 101 abzunehmende Druckform 111 bildet und zum anderen die Anstellung der aufzubringenden Druckform 112 an die Oberfläche des Plattenzylinders 101 unterstützt.The
Fig. 2 zeigt ein in seine Betriebsposition geschwenktes Halteelement.Fig. 2 shows a holding element pivoted into its operating position.
Die beiden Zylinder 101 und 110 drehen langsam rückwärts, wobei die Schutzeinrichtung 108 aus dem Spalt zwischen den Zylinderoberflächen weggeschwenkt wird. Das verschwenkbare Halteelement 103 schwingt in eine zur Führung 104 parallele Position und definiert mit dieser einen Einlaufspalt. Das Andrückelement 107 wird nun an die Oberfläche der abzunehmenden Druckform 111 angestellt.The two
In Fig. 3 ist die Freigabe eines hinteren Druckformendes dargestellt.In Fig. 3 the release of a rear printing form end is shown.
Die Halteeinrichtung 113 im Kanal 114 des Druckformzylinders 101 gibt das hintere Ende der abzunehmenden Druckform 111 frei. Aufgrund der der Druckform 111 innewohnenden Elastizität, fährt das Ende der Druckform 111 aus dem Kanal 114 aus und schlägt am Vorsprung 109 des schwenkbaren Halteelementes 103 an. Die langsame rückwärtige Bewegung des Druckformzylinders 101 bewirkt, daß der rückwärtige Teil der vom Druckformzylinder 101 abzunehmenden Druckform 111 in den durch den Vorsprung 109 und die Führung 104 gebildeten Einlaufkanal in die vordere Kammer 123 einläuft. Durch den Vorsprung 109 wird die sich durch die Eigensteifigkeit der Druckform 111 ergebende Krümmung der Druckform 111 gerade so gehalten, daß die Druckform 111 die Oberfläche des Übertragungszylinders 110 während der Abnahme vom Druckformzylinder 101 nicht kontaktiert.The holding
In Fig. 4 ist der Zustand gezeigt, in welchem die erste Druckform 111 schon weitgehend in die vordere Kammer 123 eingefahren ist. Nunmehr wird das untere Aufnahmeelement 106 aktiviert, welche die vom Zylinder 101 abzunehmende Druckform 111 abbremst. Da die erste Druckform 111 nun durch das untere Aufnahmeelement 106 fixiert wird, gibt die Halteeinrichtung 113 auch die Vorderkante 120 der Druckform 111 frei. Durch die Elastizität der ersten Druckform 111 fährt nunmehr auch die Vorderkante 120 aus dem Kanal 114 aus; die erste Druckform 111 ist nunmehr nur durch das untere Aufnahmeelement 105 gehalten.4 shows the state in which the
Nunmehr setzt der Zylinder seine rückwärts gerichtete Rotation fort, wodurch - dank der Anstellung der ersten Druckform 111 an dessen Oberfläche und den dadurch bewirkten Rollkontakt - die Druckform 111 weiter in die vordere Kammer 123 geschoben wird. Das Aufnahmeelement 106 gibt nunmehr die erste Druckform 111 frei; das schwenkbare Halteelement 103 schwenkt nach oben an die zweite, die nunmehr aufzubringende Druckform 112 an. Die freigegebene, erste Druckform 111 fährt nunmehr, bedingt durch die Schwerkraft, in die vordere Kammer 123 des Druckformmagazins 102 hinein.Now the cylinder continues its backward rotation, whereby - thanks to the positioning of the
Die Rotation des Zylinders 101 wird gestoppt und die oberen Aufnahmelemente 105 fixieren die zweite Druckform 112 in der hinteren, etwas hoher gelegenen Kammer 124 des Druckformmagazins 102. Da diese zweite Druckform 112 zur Förderung an die Oberfläche des Druckformzylinders 101 gebogen werden muß, sind zwei Aufnahmeelemente 105 am schwenkbaren Halteelement 103 vorgesehen. Die derart fixierte Druckform 112 wird nun durch Schwenken des Halteelementes 103 an die Oberfläche des Druckformzylinders 101 angestellt.The rotation of the
Wie in Fig. 5 dargestellt, wird die Vorderkante 120 der Druckform 112 durch das Verschwenken des Halteelemente 103 an die Oberfläche des Druckformzylinders 101 angestellt. Das Andrückelement 107 wird vom Zylinder 101 abgestellt, der Druckformzylinder 101 dreht sich langsam vorwärts. Bei der Passage des Kanals 114 federt die Vorderkante 120 der zweiten Druckform 112 in die Halteeinrichtung 113 ein, wodurch die zweite Druckform 112 langsam auf den Umfang des Druckformzylinders 101 gezogen wird. Wahrend des Aufziehens der zweiten Druckform 112 bleiben die oberen Aufnahmeelemente 105 aktiviert.
