Insbesondere im Mehrfarbendruck ist es für die Qualität eines herzustellenden Druckerzeugnisses wichtig, dass am Druck desselben Druckbildes beteiligte Druckformen in im Druckprozess einander nachfolgenden Druckwerken einer Druckmaschine registerhaltig an ihrem jeweiligen Formzylinder angeordnet sind, um voneinander verschiedene, von unterschiedlichen Druckwerken gedruckte, aber zu demselben Druckbild gehörende Farbauszüge des Druckerzeugnisses auf dem Bedruckstoff passgenau aufeinander zu drucken. Um eine registerhaltige, insbesondere Seiten registerhaltige Ausrichtung und Zuführung von Druckformen zu ihrem jeweiligen Formzylinder zu ermöglichen, werden die am Druckprozess beteiligten Druckformen folgendermaßen vorbereitet.In multi-color printing in particular, it is important for the quality of a printed product to be produced that printing forms involved in the printing of the same print image are arranged in register in the printing units of a printing press which follow one another in the printing process on their respective forme cylinders in order to have different printing units printed by different printing units but belonging to the same printing image To print color separations of the printed product on the substrate precisely on each other. In order to enable registering, in particular page registration, alignment and feeding of printing forms to their respective forme cylinders, the printing forms involved in the printing process are prepared as follows.
Eine z. B. in einem Offsetdruckverfahren einzusetzende Druckform 02 wird derart hergestellt, dass eine Rohdruckform mit einem Druckbild bebildert (Fig. 2 und 3) und ihre Form dem beabsichtigten Einsatz in einer Druckmaschine angepasst wird. Die Rohdruckform kann z. B. aus einer dünnen, flexiblen, rechteckförmigen Platte bestehen, wobei deren Längen- und Breitenmaß eine Toleranz von z. B. ± 1 mm aufweisen kann. Diese große Toleranz ist insbesondere für im Mehrfarbendruck einzusetzende Druckformen 02 nicht akzeptabel, da Register im Druckprozess, z. B. Seitenregister, Umfangsregister, Farbregister, z. B. mit einer Genauigkeit zwischen 0,005 mm und 0,03 mm, vorzugsweise zwischen 0,01 mm und 0,02 mm eingestellt sein müssen, um ein qualitativ akzeptables Druckerzeugnis mit einem Druckbild ausreichender Bildschärfe herzustellen.A z. B. to be used in an offset printing process, printing form 02 is produced in such a way that a raw printing form is illustrated with a print image (FIGS. 2 and 3) and its shape is adapted to the intended use in a printing press. The Printing form can z. B. consist of a thin, flexible, rectangular plate, the length and width of which have a tolerance of z. B. can have ± 1 mm. This large tolerance is particularly unacceptable for printing forms 02 to be used in multicolor printing, since registers in the printing process, e.g. B. page register, circumferential register, color register, z. B. must be set with an accuracy between 0.005 mm and 0.03 mm, preferably between 0.01 mm and 0.02 mm in order to produce a qualitatively acceptable printed product with a print image of sufficient image sharpness.
Die zu bebildernde Fläche der Druckform 02 ist ihre Arbeitsfläche. Die Arbeitsfläche der Druckform 02 wird innerhalb eines durch zwei parallele Linien begrenzten Satzspiegels 11 durch eine Bebilderungsvorrichtung oder in einer Bebilderungsvorrichtung mit einem Druckbild z. B. fotografisch bebildert. Die zwei parallelen Linien 12; 13 des Satzspiegels 11 sind dabei parallel zur Transportrichtung eines das Druckbild im Druckprozess in der Druckmaschine aufnehmenden Bedruckstoffes ausgerichtet. Es wird zumindest eine Kante 14 der Druckform 02 nach der Bebilderung der Arbeitsfläche parallel zu den beiden parallelen Linien 12; 13 des Satzspiegels 11 beschnitten. Vorzugsweise werden zwei parallele Kanten 14; 16 der Druckform 02 nach der Bebilderung der Arbeitsfläche parallel zu den beiden parallelen Linien 12; 13 des Satzspiegels 11 beschnitten. Damit erfolgt der Beschnitt der zumindest einen Kante 14; 16 der Druckform 02 in Abhängigkeit von dem auf der Druckform 02 aufgebrachten Druckbild, sodass mindestens diese eine Kante 14; 16 stets parallel zum Satzspiegel 11 ausgerichtet ist. Die beschnittene Kante 14; 16 hat also immer einen festen Bezug zu dem auf der Druckform 02 aufgebrachten Druckbild. Diese Maßnahme ist vorteilhaft, da dadurch ein registerhaltiges Ausrichten des Druckbildes erleichtert wird. Wenn sichergestellt ist, dass die Druckform 02 exakt parallel zur Transportrichtung des das Druckbild aufnehmenden Bedruckstoffes einem Formzylinder 01 der Druckmaschine zugeführt und auf dem Formzylinder 01 montiert wird, werden am Formzylinder 01 für die Registereinstellung der Druckform 02 entsprechende EinStellvorrichtungen, z. B. Registerstifte o. ä. nicht mehr benötigt. Im Herstellungsverfahren der registerh altigen Druckform 02 wird diese in der Ebene ihrer Arbeitsfläche vorzugsweise in zwei zueinander orthogonalen Richtungen verschiebbar gelagert, wobei der Verschiebeweg im Bereich weniger hunderstel Millimeter liegt. Gleichfalls wird die Druckform 02 in der Ebene ihrer Arbeitsfläche vorzugsweise um eine zur Arbeitsfläche der Druckform 02 lotrechte Achse drehbar gelagert. Dazu kann ein auch drehbarer XY-Tisch vorgesehen sein, der für die aufliegende Druckform 02 eine hohe Positioniergenauigkeit gewährleistet.The area of the printing form 02 to be imaged is its working area. The working surface of the printing form 02 is within a type area 11 delimited by two parallel lines by an imaging device or in an imaging device with a print image, e.g. B. photographically illustrated. The two parallel lines 12; 13 of the type area 11 are aligned parallel to the transport direction of a printing material receiving the print image in the printing process in the printing press. At least one edge 14 of the printing form 02 is drawn parallel to the two parallel lines 12; 13 of the type area 11 cropped. Preferably two parallel edges 14; 16 of the printing form 02 after the illustration of the work surface parallel to the two parallel lines 12; 13 of the type area 11 cropped. This trims the at least one edge 14; 16 of the printing form 02 as a function of the printing image applied to the printing form 02, so that at least this one edge 14; 16 is always aligned parallel to the type area 11. The trimmed edge 14; 16 therefore always has a fixed reference to the printed image applied to the printing form 02. This measure is advantageous because it facilitates register-oriented alignment of the print image. If it is ensured that the printing form 02 is fed to a forme cylinder 01 of the printing press and mounted on the forme cylinder 01 exactly parallel to the transport direction of the printing material receiving the print image, corresponding adjusting devices, e.g. B. register pins or the like are no longer required. In the manufacturing process of the registered printing form 02, it is preferably mounted so that it can be displaced in the plane of its working surface in two mutually orthogonal directions, the displacement path being in the range of a few hundredths of a millimeter. Likewise, the printing form 02 is preferably rotatably mounted in the plane of its working surface about an axis perpendicular to the working surface of the printing form 02. For this purpose, an XY table, which can also be rotated, can be provided, which ensures a high positioning accuracy for the printing form 02 lying thereon.
Es ist vorteilhaft vorzusehen, dass die Druckform 02 an mindestens einer zu ihrer mindestens einen beschnittenen Kante 14; 16 orthogonalen Kante 17 mit einem winklig abgebogenen Schenkel 18 versehen wird (Fig. 1 ), wobei der abgebogene Schenkel 18 der Montage der Druckform 02 auf dem Formzylinder 01 dient und wobei die Abkantung des Schenkels 18 vorzugsweise nach dem Beschnitt der Kante 14; 16 erfolgt. Dieser abgebogene Schenkel 18 ist insbesondere am vorlaufenden Ende der Druckform 02 ausgebildet. Der Abbiegewinkel kann z. B. ausgehend von der Arbeitsfläche der Druckform 02 zwischen 45° und 135° liegen, vorzugsweise z.B. bei 45° ± 10° oder bei 90 °± 10°. Die Biegjng des Schenkels 18 erfolgt in eine von der Arbeitsfläche der Druckform 02 abgewandte Richtung. Die Druckform 02 kann vorzugsweise auch an zwei parallelen zu ihrer beschnittenen Kante 14; 16 orthogonalen Kanten 17; 19 jeweils mit einem winklig abgebogenen Schenkel 18; 21 versehen werden, also auch an ihrem nachlaufenden Ende einen abgewinkelten Schenkel 21 aufweisen (in den Fig. 2 und 3 sind die Kante 17 und der daran ausgebildete Schenkel 18 der Druckform 02 verdeckt). Vorzugsweise wird die Arbeitsfläche der Druckform 02 rechteckförmig ausgebildet, wobei die Arbeitsfläche durch zwei parallele beschnittene Kanten 14; 16 und zwei dazu rechtwinklige Biegekanten 17; 19 begrenzt ist. Der Abbiegewinkel der Schenkel 18; 21 ist vorzugsweise derart gewählt, dass die Druckform 02 mittels einer Vorrichtung automatisch, d. h. durch eine fernbetätigbare Stelleinrichtung, zugeführt und gleichfalls automatisch auf der Mantelfläche des Formzylinders 01 montiert und befestigt werden kann.It is advantageous to provide that the printing form 02 has at least one edge 14; 16 orthogonal edge 17 is provided with an angularly bent leg 18 (FIG. 1), the bent leg 18 being used for mounting the printing form 02 on the forme cylinder 01 and wherein the bending of the leg 18 is preferably carried out after trimming the edge 14; 16 takes place. This bent leg 18 is formed in particular at the leading end of the printing form 02. The turning angle can e.g. B. starting from the working surface of the printing forme 02 are between 45 ° and 135 °, preferably for example at 45 ° ± 10 ° or at 90 ° ± 10 °. The bending of the leg 18 takes place in a direction facing away from the working surface of the printing form 02. The printing form 02 can preferably also on two parallel to its trimmed edge 14; 16 orthogonal edges 17; 19 each with an angled leg 18; 21 are provided, ie also have an angled leg 21 at their trailing end (in FIGS. 2 and 3, the edge 17 and the leg 18 of the printing form 02 formed thereon are covered). The working surface of the printing form 02 is preferably of rectangular design, the working surface being formed by two parallel trimmed edges 14; 16 and two bending edges 17 at right angles thereto; 19 is limited. The bending angle of the legs 18; 21 is preferably selected such that the printing form 02 is fed automatically by means of a device, that is to say by means of a remotely operable actuating device, and likewise can be automatically mounted and fastened on the outer surface of the forme cylinder 01.
Im Herstellungsverfahren der registerhaltigen Druckform 02, insbesondere in Verbindung mit ihrer Bebilderung, wird ihre Arbeitsfläche mit mindestens zwei voneinander beabstandeten Markierungen versehen, anhand derer die mindestens eine zu beschneidende Kante 14; 16 der Druckform 02 parallel zu den beiden Linien 12; 13 des Satzspiegels 11 ausgerichtet wird. Die Markierungen können auf der Arbeitsfläche der Druckform 02 außerhalb des Satzspiegels 11 angebracht werden. Vorteilhaft ist jedoch die Ausbildung der Markierungen innerhalb des Satzspiegels 11 und/oder im Bereich des mindestens einen abzukantenden Schenkels 18; 21 , insbesondere auf einem der abzukantenden Schenkel 18; 21. Es ist vorteilhaft, innerhalb des Satzspiegels 11 auf der Arbeitsfläche der Druckform 02 angebrachte Markierungen nahe der Biegekanten 17; 19 anzubringen, damit die Markierungen einen möglichst großen Abstand voneinander aufweisen. So ist ein nahezu über die gesamte Länge der Druckform 02 reichender Abstand L von Vorteil (Fig. 1 ). Die Markierungen können auch als ein Teil des Druckbildes ausgebildet sein. Die Markierungen werden vorzugsweise maschinendetektierbar ausgebildet, z. B. als ein Kreuz oder als ein Kreis. Die Markierungen sind derart ausgebildet, dass sie vorzugsweise mit einem Sensor, z. B. mit einem optischen Sensor detektiert werden können, insbesondere mit einer Videokamera, wobei der Sensor sein Ausgangssignal einer das Ausgangssignal auswertenden Steuereinrichtung zur Verfügung stellt. Ein als eine Videokamera ausgebildeter Sensor stellt sein Ausgangssignal einer bildauswertenden Steuereinrichtung zur Verfügung.In the manufacturing process of the register-containing printing form 02, in particular in connection with its illustration, its working surface is provided with at least two markings spaced apart from one another, on the basis of which the at least one edge 14; 16 of the printing form 02 parallel to the two lines 12; 13 of the type area 11 is aligned. The markings can be placed on the working surface of the printing form 02 outside the type area 11. However, the formation of the markings within the type area 11 and / or in the region of the at least one leg 18 to be bent is advantageous; 21, in particular on one of the legs 18; 21. It is advantageous to place markings inside the type area 11 on the working surface of the printing form 02 near the bending edges 17; 19 so that the markings are as far apart as possible. A distance L extending almost over the entire length of the printing form 02 is advantageous (FIG. 1). The markings can also be formed as part of the printed image. The markings are preferably made machine-detectable, e.g. B. as a cross or as a circle. The markings are designed such that they are preferably connected to a sensor, e.g. B. can be detected with an optical sensor, in particular with a video camera, the sensor making its output signal available to a control device evaluating the output signal. A sensor designed as a video camera makes its output signal available to an image-evaluating control device.
Die während ihrer Herstellung in einer Verstellvorrichtung verschiebbar und/oder drehbar gelagerte Druckform 02 wird z. B. von der Steuereinrichtung in Abhängigkeit von den detektierten Markierungen vor dem Beschnitt ihrer Kante(n) 14; 16 und/oder vor der Biegung ihres/ihrer Schenkel(s) 18; 21 in ihrer Lage ausgerichtet. Dazu wird die in der Verstellvorrichtung ausgerichtete Druckform 02 vor dem Beschnitt ihrer Kante(n) 14; 16 und/oder vor der Biegung ihres/ihrer Schenkel(s) 18; 21 in der ausgerichteten Lage z. B. mit einer Saugvorrichtung fixiert. Vorzugsweise erst nach dem Beschnitt der Kante(n) 14; 16 und/oder nach der Biegung des/der Schenkel(s) 18; 21 der Druckform 02 wird die Fixierung wieder gelöst, sodass die in ihrer Lage ausgerichtete Druckform 02 während ihrer mechanischen Bearbeitung durch Beschnitt und/oder Biegung der Kante(n) 14; 16 fixiert bleibt. Beschnitt und Biegung der Kante(n) 14; 16 erfolgt demnach vorzugsweise ohne eine zwischenzeitliche Veränderung der Lage der ausgerichteten Druckform 02.The movable and / or rotatably mounted printing form 02 during its manufacture in z. B. by the control device depending on the detected markings before trimming their edge (s) 14; 16 and / or before the bend of their leg (s) 18; 21 aligned in their position. For this purpose, the printing form 02 aligned in the adjusting device is trimmed prior to the trimming of its edge (s) 14; 16 and / or before the bend of her leg (s) 18; 21 in the aligned position z. B. fixed with a suction device. Preferably only after the edge (s) 14; 16 and / or after the bending of the leg (s) 18; 21 of the printing form 02, the fixation is released again, so that the printing form 02 aligned in its position during its mechanical processing by trimming and / or bending the edge (s) 14; 16 remains fixed. Trimming and bending of the edge (s) 14; 16 therefore preferably takes place without an interim change in the position of the aligned printing form 02.
Es ist ein besonderer Vorteil, dass die in der zuvor beschriebenen Weise angefertigte Druckform 02 ohne eine Registerstanzung ausgebildet wird und ohne eine Registerstanzung in der Druckmaschine einsatzbereit ist.It is a particular advantage that the printing form 02 produced in the manner described above is designed without a register punch and is ready for use in the printing press without a register punch.
Die mittels des zuvor beschriebenen Verfahrens hergestellte Druckform 02 wird mit ihrer zumindest einen nach der Bebilderung ihrer Arbeitsfläche parallel zu den parallelen Linien 12; 13 des Satzspiegels 11 beschnittenen Kante 14; 16 dem Formzylinder 01 der Druckmaschine zugeführt, während des Zuführens für eine registerhaltige Positionierung seitlich zu diesem Formzylinder 01 ausgerichtet und dort auf dem Formzylinder 01 montiert. Außer der positionsgenauen Anordnung bewirkt die seitliche Ausrichtung der Druckform 02 auch, dass die beschnittene Kante 14; 16 der Druckform 02 und damit auch die zu dieser Kante 14; 16 parallelen Linien 12; 13 ihres Satzspiegels 11 orthogonal zur Achse 22 des Formzylinders 01 ausgerichtet werden. In den Figuren ist jeweils nur ein einziger Formzylinder 01 angedeutet, jedoch versteht sich, dass die vorgeschlagene Vorrichtung an allen am Druckprozess für ein bestimmtes Druckerzeugnis beteiligten Druckwerken vorgesehen sein kann, sodass mehrere dieser Vorrichtungen in derselben Druckmaschine angeordnet sind. Aus Gründen der Übersichtlichkeit wurde hier auf eine mehrfache Darstellung der Vorrichtung verzichtet.The printing form 02 produced by means of the previously described method is parallel to the parallel lines 12; 13 of the type area 11 trimmed edge 14; 16 fed to the forme cylinder 01 of the printing press, aligned laterally to this forme cylinder 01 during the feeding for register-based positioning and mounted there on the forme cylinder 01. In addition to the precise positioning, the lateral alignment of the printing form 02 also causes the trimmed edge 14; 16 of the printing form 02 and thus also the edge 14; 16 parallel lines 12; 13 of its type area 11 are aligned orthogonally to the axis 22 of the forme cylinder 01. Only a single forme cylinder 01 is indicated in the figures, but it goes without saying that the proposed device can be provided on all printing units involved in the printing process for a specific printed product, so that several of these devices are arranged in the same printing press. For reasons of clarity, the device has not been shown multiple times.
Im Folgenden wird die Vorrichtung zur Zuführung eines registerhaltig hergestellten Aufzugs 02, vorzugsweise einer registerhaltig hergestellten Druckform 02 zum Formzylinder 01 näher beschrieben. Die in axialer Richtung positionsgenaue Zuführung der Druckform 02 zum Formzylinder 01 erfolgt z. B. über einen Tisch oder aus einem Magazin heraus, und zwar vorzugsweise derart, dass ein abgekantetes Ende der Druckform 02 in einen sich in Längsrichtung des Formzylinders 01 unter dessen Mantelfläche erstreckenden Kanal 28 eingeführt werden kann, wobei der Kanal 28 an der Mantelfläche des Formzylinders 01 eine z. B. schlitzförmige Öffnung 29 vorzugsweise mit einer Schlitzweite S zwischen 1 mm und 3 mm aufweist (Fig. 2 und 3). Im Kanal 28 ist eine Halte Vorrichtung 03 angeordnet, wobei die Haltevorrichtung 03 in der bevorzugten Ausführung als eine im Kanal 28 angeordnete Klemmvorrichtung 03 ausgebildet ist (Fig. 1 ). Die Enden der Druckform 02 können jedoch auch durch die Formgebung von Ende und Kanal 28 ohne Klemmeinrichtung 03, d. h. allein durch einen Formschluss, gehalten werden. Damit die Druckform 02 hinsichtlich der axialen Richtung des Formzylinders 01 in der richtigen Lage, d. h. in einer zur axialen Richtung des Formzylinders 01 orthogonalen Ausrichtung, zugeführt und gegebenenfalls fixiert wird, ist außerhalb des Formzylinders 01 eine Vorrichtung 04 zum Führen der registerhaltig hergestellten Druckform 02 vorgesehen.In the following, the device for feeding an elevator 02 produced in register, preferably a printing form 02 manufactured in register, is used for Forme cylinder 01 described in more detail. The positionally accurate feeding of the printing form 02 to the forme cylinder 01 takes place, for. B. over a table or out of a magazine, preferably in such a way that a folded end of the printing form 02 can be inserted into a channel 28 extending in the longitudinal direction of the forme cylinder 01 under its outer surface, the channel 28 on the outer surface of the forme cylinder 01 a z. B. slot-shaped opening 29 preferably with a slot width S between 1 mm and 3 mm (Fig. 2 and 3). A holding device 03 is arranged in the channel 28, the holding device 03 in the preferred embodiment being designed as a clamping device 03 arranged in the channel 28 (FIG. 1). However, the ends of the printing form 02 can also be held by the shaping of the end and the channel 28 without a clamping device 03, that is to say solely by a positive fit. A device 04 for guiding the printing form 02 produced in register is provided outside the form cylinder 01 so that the printing form 02 is supplied in the correct position, ie in an orientation orthogonal to the axial direction of the form cylinder 01, with respect to the axial direction of the form cylinder 01 ,
Die Vorrichtung 04 zum Führen der Druckform 02 weist z. B. eine zur Achse 22 des Formzylinders 01 , d. h. in dessen Längsrichtung, im Wesentlichen parallele Schwenkachse 26 auf, um welche mindestens ein Anschlag 06; 07 schwenkbar ist. Dieser Anschlag 06; 07 ist beispielsweise abgeschwenkt für eine Betriebssituation, in welcher kein Druckformwechsel stattfinden soll und angeschwenkt, wenn eine Druckform 02 zugeführt wird. Über die Länge des Formzylinders 01 , welche im Wesentlichen der Breite von z. B. vier Druckseiten, z. B. Zeitungsseiten, entspricht, sind z. B. vier derartige Anschläge 06 (für jede von den vier Druckformen 02 jeweils einer) an einer Welle angeordnet. Die Druckformen 02 werden z. B. mittels Federkraft (nicht dargestellt) an den jeweiligen seitlichen Anschlag 06; 07 gedrückt. Es sind z. B. zusätzlich über die Länge des Formzylinders 01 bzw. der Welle zwei Anschläge 07 vorgesehen, welche für den Fall doppelt breiter Druckformen 02 anschwenkbar sind. Die verschwenkbaren Anschläge 06; 07 sind z. B. in eine Anordnung eines voll- oder halbautomatischen Plattenwechslers integrierbar. Die axiale Position der Anschläge 06; 07, die z. B. als dünne Platten („Flügel") an einer zu verschwenkenden Traverse 27, z. B. einem Vierkantrohr, angeordnet sind, kann gegebenenfalls eigens oder/und die gesamte Vorrichtung 04 zum Führen der Druckform 02 justierbar sein. Insbesondere können die Anschläge 06; 07 zur Veränderung ihrer jeweiligen Position in Axialrichtung 22 des Formzylinders 01 an der Traverse 27 zumindest innerhalb eines definierten Stellbereichs verschiebbar angeordnet sein.The device 04 for guiding the printing form 02 has, for. B. on the axis 22 of the forme cylinder 01, ie in its longitudinal direction, substantially parallel pivot axis 26 about which at least one stop 06; 07 is pivotable. This stop 06; 07 is, for example, pivoted away for an operating situation in which no printing form change is to take place and pivoted when a printing form 02 is fed. Over the length of the forme cylinder 01, which is essentially the width of z. B. four printed pages, e.g. B. newspaper pages, are z. B. four such stops 06 (one for each of the four printing plates 02) arranged on a shaft. The printing forms 02 are z. B. by means of spring force (not shown) on the respective lateral stop 06; 07 pressed. There are e.g. B. in addition over the length of the forme cylinder 01 or the shaft two stops 07 are provided, which can be pivoted 02 in the case of double-wide printing plates. The pivotable stops 06; 07 are e.g. B. can be integrated into an arrangement of a fully or semi-automatic plate changer. The axial position of the stops 06; 07, the z. B. are arranged as thin plates ("wings") on a crossbar 27 to be pivoted, for example a square tube, can optionally or / and the entire device 04 for guiding the printing form 02 be adjustable. In particular, the stops 06 ; 07 to change their respective position in the axial direction 22 of the forme cylinder 01 on the cross member 27 can be arranged at least within a defined adjustment range.
In einer Weiterbildung weist die Vorrichtung 04 zum Führen der Druckform 02 auf einer von den Anschlägen 06; 07 verschiedenen Seite eine Rolle 08 oder mehrere Rollen 08 auf, welche zum Abnehmen der Druckform 02 vom Formzylinder 01 nach entsprechendem Verschwenken der Vorrichtung 04 zum Führen der Druckform 02 die anzunehmende Druckform 02 niederhalten, sodass diese positionsgenau auf dem Tisch, z. B. an einem Anschlag 06; 07 zu liegen kommt. Eine weitere Hilfsvorrichtung 09 für das Aufziehen oder Abnehmen der Druckform 02 kann gleichfalls eine Rolle oder mehrere anstellbare Rolle aufweisen (Fig. 1).In one development, the device 04 for guiding the printing form 02 has one of the stops 06; 07 different side a roll 08 or more rolls 08, which hold the printing plate 02 to be accepted for removing the printing form 02 from the form cylinder 01 after corresponding pivoting of the device 04 for guiding the printing form 02, so that these are positioned precisely on the table, e.g. B. at a stop 06; 07 comes to rest. Another auxiliary device 09 for pulling or removing the printing form 02 can likewise have one roll or several rollable rolls (FIG. 1).
Für diese Vorrichtung 04 zum seitlichen Ausrichten mindestens einer einem Formzylinder 01 einer Druckmaschine zuzuführenden Druckform 02, wobei mindestens ein in axialer Richtung des Formzylinders 01 wirksamer, die zuzuführende Druckform 02 seitlich ausrichtender Anschlag 06; 07 außerhalb des Formzylinders 01 in einer Zuführebene der Druckform 02 angeordnet ist, ist vorzugsweise vorgesehen, dass die zuvor zugeführte Druckform 02 oder eine andere auf dem Formzylinder 01 angeordnete Druckform 02 in einer Abführebene 23 der Druckform 02 vom Formzylinder 01 abführbar ist. Falls der Anschlag 06; 07 während des Zuführens der Druckform 02 zumindest teilweise in die Abführebene 23 greift, ist sicherzustellen, dass der Anschlag 06; 07 während des Abführens der Druckform 02 aus der Abführebene 23 entfernt ist, weshalb der Anschlag 06; 07 aus der Abführebene 23 z. B. durch eine Schwenkbewegung herausgeführt wird, um das Abführen der Druckform 02 nicht zu behindern.For this device 04 for the lateral alignment of at least one printing forme 02 to be fed to a forme cylinder 01 of a printing press, at least one stop 06; which is more effective in the axial direction of the forme cylinder 01 and laterally aligning the printing forme 02 to be fed. 07 is arranged outside the forme cylinder 01 in a feed plane of the printing form 02, it is preferably provided that the previously supplied printing form 02 or another printing form 02 arranged on the form cylinder 01 can be removed from the form cylinder 01 in a discharge plane 23 of the printing form 02. If the stop 06; 07 during the feeding of the printing form 02 at least partially reaches into the discharge plane 23, it must be ensured that the stop 06; 07 is removed from the discharge plane 23 during the removal of the printing form 02, which is why the stop 06; 07 from the discharge level 23 z. B. is brought out by a pivoting movement, so as not to hinder the removal of printing form 02.
Fig. 3 zeigt in Axialrichtung des Formzylinders 01 mehrere nebeneinander angeordnete zuzuführende Druckformen 02 und eine vom Formzylinder 01 abzuführende Druckform 02, wobei die abzuführende Druckform 02 unterhalb der Zuführebene 24 vom Formzylinder 01 abgeführt wird. In der Darstellung der Fig. 3 verdeckt die Zuführebene 24 die in ihrer Abführebene 23 abzuführende Druckform 02 zum größten Teil.3 shows in the axial direction of the forme cylinder 01 a plurality of printing forms 02 to be supplied arranged next to one another and a printing form 02 to be discharged from the forme cylinder 01, the printing form 02 to be discharged being discharged from the forme cylinder 01 below the feed plane 24. In the illustration in FIG. 3, the feed plane 24 largely covers the printing form 02 to be discharged in its discharge plane 23.
Vorzugsweise sind die Zuführebene 24 der Druckform 02 und die Abführebene 23 der Druckform 02 zueinander versetzt angeordnet, z. B. vertikal zueinander versetzt angeordnet (Fig. 2 und 3). In einer besonderen Ausführung können sich die Zuführebene 24 der Druckform 02 und die Abführebene 23 der Druckform 02 zumindest teilweise überlappen, also zumindest teilweise deckungsgleich und sogar identisch sein. Der Anschlag 06; 07 ist um die zur Längsachse des Formzylinders 01 im Wesentlichen parallele Schwenkachse 26 in die Zuführebene 24 der Druckform 02 hinein oder aus dieser heraus schwenkbar angeordnet. Der Anschlag 06; 07 ist vorzugsweise auf der schwenkbaren Traverse 27 angeordnet. Mit dem Anschlag 06; 07 ist die Druckform 02 dem Formzylinder 01 in axialer Richtung positionsgenau zuführbar, wobei die axiale Position des Anschlags 06; 07 vorzugsweise justierbar ausgeführt ist und dafnit bedarfsgerecht unterschiedliche Betriebsstellungen aufweisen kann. Wenn über die Länge des Formzylinders 01 mehrere, z. B. vier axial voneinander beabstandete Anschläge 06 vorgesehen sind, so sind diese Anschläge 06 vorzugsweise gleichzeitig schwenkbar. An unterschiedlicher axialer Position angeordnete Anschläge 06; 07 können aber auch zu unterschiedlichen Zeitpunkten in die Abführebene 23 der Druckform 02 eingreifen. Für die Vorrichtung 04 zum Führen der Druckform 02 sind demnach infolge der Schwenkbewegung um die Schwenkachse 26 unterschiedliche Betriebsstellungen definiert, und zwar, ob überhaupt einer der Anschläge 06; 07 in die Zuführebene 24 und/oder die Abführebene 23 der Druckform 02 greift und wenn dem so ist, welcher der Anschläge 06; 07 in die Zuführebene 24 und/oder die Abführebene 23 der Druckform 02 greift. Ein Anschlag 06 zum Ausrichten einer schmalen Druckform 02 greift zu einem anderen Zeitpunkt in die Abführebene 23 der Druckform 02 ein als ein eine breite Panoramadruckform 02 ausrichtender Anschlag 07, wobei eine Panoramadruckform 02 in axialer Richtung des Formzylinders 01 z. B. die doppelte Breite einer normal breiten Druckform 02 aufweist. Gleichfalls können an unterschiedlicher axialer Position angeordnete Anschläge 06; 07 zu voneinander verschiedenen Zeitpunkten aus der Abführebene 23 der Druckform 02 entfernt sein. Des Weiteren sind in einer Betriebsstellung an unterschiedlicher axialer Position angeordnete Anschläge 06; 07 gleichzeitig aus der Abführebene 23 entfernt. Die Vorrichtung 04 zum Führen der Druckform 02 ist hinsichtlich ihrer unterschiedlichen Betriebsstellungen fernbetätigbar, vorzugsweise von einer der Druckmaschine zugeordneten Steuereinrichtung, z. B. einem Leitstand, steuerbar.Preferably, the feed plane 24 of the printing form 02 and the discharge plane 23 of the printing form 02 are arranged offset from one another, for. B. vertically offset from each other (Fig. 2 and 3). In a special embodiment, the feed plane 24 of the printing form 02 and the discharge plane 23 of the printing form 02 can at least partially overlap, that is to say they are at least partially congruent and even identical. The stop 06; 07 is arranged so as to be pivotable about the pivot axis 26, which is essentially parallel to the longitudinal axis of the forme cylinder 01, into or out of the feed plane 24 of the printing form 02. The stop 06; 07 is preferably arranged on the pivotable cross member 27. With the stop 06; 07, the printing form 02 can be fed to the forme cylinder 01 in the axial direction with exact position, the axial position of the stop 06; 07 is preferably adjustable and can therefore have different operating positions as required. If over the length of the forme cylinder 01 several, for. B. four axially spaced stops 06 are provided, these stops 06 are preferably pivotable at the same time. Stops 06; arranged at different axial positions; 07 can also intervene in the discharge plane 23 of the printing form 02 at different times. Accordingly, different operating positions are defined for the device 04 for guiding the printing form 02 as a result of the pivoting movement about the pivot axis 26, specifically whether one of the stops 06; 07 engages in the feed plane 24 and / or the discharge plane 23 of the printing form 02 and, if so, which of the stops 06; 07 into the feed plane 24 and / or the discharge plane 23 of the printing form 02 attacks. A stop 06 for aligning a narrow printing form 02 engages in the discharge plane 23 of the printing form 02 at a different time than a stop 07 aligning a wide panoramic printing form 02, with a panorama printing form 02 in the axial direction of the forme cylinder 01 e.g. B. has twice the width of a normal wide printing form 02. Likewise, stops 06; 07 at different times from the discharge plane 23 of the printing form 02. Furthermore, in an operating position, stops 06; 07 removed from the discharge level 23 at the same time. The device 04 for guiding the printing form 02 can be operated remotely with regard to its different operating positions, preferably by a control device assigned to the printing press, e.g. B. a control center, controllable.
Der Anschlag 06; 07 wirkt auf den seitlichen Rand der Druckform 02, insbesondere auf zumindest eine der beschnittenen Kanten 14; 16, die parallel zu dem auf der Druckform 02 aufgebrachten Druckbild, d. h. parallel zu einer Begrenzungslinie 12; 13 von dessen Satzspiegel 11 , ausgerichtet ist. Dadurch, dass die Druckform 02, deren zumindest eine beschnittene Kante 14; 16 in einer festen Relation zu dem auf der Druckform 02 aufgebrachten Druckbild steht, in einer durch den Anschlag 06; 07 positionsgenauen Ausrichtung dem Formzylinder 01 zugeführt wird, kann diese Druckform 02 auf der Mantelfläche des Formzylinders 01 registerhaltig montiert werden, ohne dass es weiterer Einstellmittel zur Registerung dieser Druckform 02 bedarf.The stop 06; 07 acts on the lateral edge of the printing form 02, in particular on at least one of the trimmed edges 14; 16, which is parallel to the printed image applied to the printing form 02, i. H. parallel to a boundary line 12; 13 of the type area 11, is aligned. The fact that the printing form 02, the at least one trimmed edge 14; 16 is in a fixed relation to the printed image applied to the printing form 02, in a position indicated by the stop 06; 07 positionally accurate alignment is fed to the forme cylinder 01, this printing form 02 can be mounted in register on the lateral surface of the forme cylinder 01 without the need for further adjustment means for registering this printing form 02.
Um ein Verklemmen der zuzuführenden Druckform 02 während ihrer Zuführung zum Formzylinder 01 wirksam zu vermeiden, ist zu beiden sich längs zur Zuführrichtung erstreckenden Seiten der zuzuführenden Druckform 02 jeweils mindestens ein in axialer Richtung des Formzylinders 01 wirksamer, die zuzuführende Druckform 02 seitlich ausrichtender Anschlag 06; 07 außerhalb des Formzylinders 01 angeordnet, wobei einer von diesen beiden die zuzuführende Druckform 02 seitlich ausrichtenden Anschlägen 06; 07 in einem Lager 31 mit einem in axialer Richtung des Formzylinders 01 wirksamen Federelement 32 gelagert ist, wobei der in diesem Lager 31 gelagerte Anschlag 06; 07 gegen eine von dem Federelement 32 ausgeübte Kraft in axialer Richtung des Formzylinders 01 verschiebbar ist (Fig. 6 und 7). Somit wird mindestens eine dem Formzylinder 01 zuzuführende Druckform 02, vorzugsweise jedoch jede dem Formzylinder 01 zuzuführende Druckform 02 seitlich zwischen einem in axialer Richtung des Formzylinders 01 starren und einem federnd gelagerten Anschlag 06; 07 geführt.In order to effectively avoid jamming of the printing form 02 to be supplied while it is being fed to the forme cylinder 01, at least one stop 06, which laterally aligns the printing form 02 to be supplied, is more effective on both sides of the printing form 02 to be fed along the feed direction. 07 arranged outside the forme cylinder 01, one of these two laterally aligning stops 06; 07 is mounted in a bearing 31 with a spring element 32 which is effective in the axial direction of the forme cylinder 01, the stop 06; 07 is displaceable in the axial direction of the forme cylinder 01 against a force exerted by the spring element 32 (FIGS. 6 and 7). Thus, at least one printing forme 02 to be fed to the forme cylinder 01, but preferably each printing forme 02 to be fed to the forme cylinder 01 is laterally between a rigid in the axial direction of the forme cylinder 01 and a resilient stop 06; 07 led.
Vorzugsweise ist das Lager 31 mit dem in axialer Richtung des Zylinders 01 wirksamen Federelement 32 in oder an der in axialer Richtung des Zylinders 01 verlaufenden Traverse 27 angeordnet. In der bevorzugten Ausführung ist für jede der in axialer Richtung des Formzylinders 01 nebeneinander angeordneten Druckformen 02 ein in einem Lager 31 mit einem in axialer Richtung des Formzylinders 01 wirksamen Federelement 32 gelagerter Anschlag 06; 07 vorgesehen.The bearing 31 is preferably arranged with the spring element 32 acting in the axial direction of the cylinder 01 in or on the cross member 27 extending in the axial direction of the cylinder 01. In the preferred embodiment, for each of the printing forms 02 arranged next to one another in the axial direction of the forme cylinder 01, a stop 06; supported in a bearing 31 with a spring element 32 which is effective in the axial direction of the forme cylinder 01; 07 provided.
Eine Ausgestaltung von in einem Lager 31 mit einem in axialer Richtung des Formzylinders 01 wirksamen Federelement 32 gelagerten Anschlägen 06; 07 ist in den Fig. 4 bis 7 dargestellt, wobei Fig. 6 eine Detailansicht der Fig. 4 zeigt. Der Übersichtlichkeit halber wurde in den Fig. 2 und 3 nur der hinsichtlich der Traverse 27 jeweils starr angeordnete Anschlag 06; 07 dargestellt. In der Fig. 5 sind die in den Fig. 2 und 3 benötigten Anschläge 06; 07 vollständig dargestellt. Die Fig. 7 zeigt ausschnittsweise einen Längsschnitt durch die vorzugsweise als ein Hohlprofil ausgebildete Traverse 27, wobei das Hohlprofil z. B. einen runden (Fig. 4) oder einen rechteckigen (Fig. 5), insbesondere quadratischen Querschnitt aufweist. In den Fig. 4 bis 7 ist der hinsichtlich der Traverse 27 starre Anschlag mit dem Bezugszeichen 06 und der hinsichtlich der Traverse 27 axial bewegliche Anschlag mit dem Bezugszeichen 07 gekennzeichnet. Diese Bezugszeichen 06; 07 werden nachfolgend entsprechend dieser Zuordnung verwendet. In der Fig. 4 sind die Anschläge 06; 07 an der Traverse 27 um einen stumpfen Winkel versetzt angeordnet, in der Fig. 5 jeweils mit einem Versatz von 180°. SowoH der hinsichtlich der Traverse 27 starre Anschlag mit dem Bezugszeichen 06 als auch der hinsichtlich der Traverse 27 axial bewegliche Anschlag mit dem Bezugszeichen 07 können in axialer Richtung der Traverse 27 zumindest innerhalb eines bestimmten Stellbereichs einstellbar und damit justierbar ausgebildet sein. Ihre Eigenschaft, starr bzw. axial beweglich zu sein, bezieht sich nur auf denjenigen Betriebszustand, in welchem sie eine dem Formzylinder 01 zuzuführende Druckform 02 während des Zuführvorgangs seitlich ausrichten und/oder führen.An embodiment of stops 06; supported in a bearing 31 with a spring element 32 which is effective in the axial direction of the forme cylinder 01; 07 is shown in FIGS. 4 to 7, FIG. 6 showing a detailed view of FIG. 4. For the sake of clarity, only the stop 06; 07 shown. In FIG. 5 the stops 06; 07 fully shown. 7 shows a section of a longitudinal section through the cross member 27, which is preferably designed as a hollow profile. B. has a round (Fig. 4) or a rectangular (Fig. 5), in particular square cross-section. 4 to 7, the stop which is rigid with respect to the crossmember 27 is identified by the reference symbol 06 and the stop which is axially movable with respect to the crossmember 27 by the reference symbol 07. These reference numbers 06; 07 are used in accordance with this assignment below. 4, the stops 06; 07 arranged on the traverse 27 offset by an obtuse angle, in FIG. 5 each with an offset of 180 °. Both the stop with the reference numeral 06, which is rigid with respect to the cross member 27, and the stop with the reference numeral 07, which is axially movable with respect to the cross member 27, can be designed to be adjustable and thus adjustable in the axial direction of the cross member 27 at least within a certain adjustment range. Their property of being rigid or axially movable only relates to the operating state in which they laterally align and / or guide a printing form 02 to be fed to the forme cylinder 01 during the feeding process.
In dem in den Fig. 4 bis 6 gezeigten Beispiel ist im Inneren der Traverse 27 jeweils an jedem Lager 31 eines in axialer Richtung des Formzylinders 01 beweglichen Anschlags 07 eine Linearführung 33 vorgesehen, wobei der in axialer Richtung des Formzylinders 01 bewegliche Anschlag 07 jeweils mit dem beweglichen Teil der Linearführung 33 fest verbunden ist. In axialer Richtung des Formzylinders 01 nicht beweglich ausgebildete Anschläge 06 sind nach ihrer vorab gewählten axialen Positionierung mit der Traverse 27 fest verbunden. Die Traverse 27 weist an den Positionen der beweglichen Anschläge 07 jeweils eine Öffnung 34, z. B. ein in axialer Richtung des Formzylinders 01 gerichtetes Langloch 34 auf, um den jeweiligen beweglichen Anschlag 07 mit der im Inneren der Traverse 27 angeordneten Linearführung 33 zu verbinden. Das Federelement 32 ist innerhalb der Linearführung 33 oder stirnseitig an der Linearführung 33 angeordnet und an einer Seite mit einer gegenüber der Traverse 27 nicht beweglichen Halterung 36 verbunden (Fig. 7). Das Federelement 32 ist z. B. als eine Feder 32, insbesondere als eine schraubenförmige, zylindrische oder als eine tellerförmige Feder 32, als ein federelastischer Körper 32, z. B. ein ausreichend weicher Gummipuffer, oder als eine z. B. aus zwei zusammenwirkenden Federblechen bestehende Parallθlogrammverschiθbung ausgebildet. Ein in axialer Richtung des Formzylinders 01 gerichteter Federweg des Federelementes 32 liegt z. B. im Bereich von ± 0,5 mm bis ca. 2 mm, vorzugsweise ± 0,5 mm bis 1 mm. Das Federelement 32 ist vorzugsweise vorgespannt. Die Linearführung 33 lässt sich innerhalb eines durch den Federweg des Federelementes 32 vorgegebenen, maximal zulässigen Verschiebungsweges durch eine an den mit der Linearführung 33 verbundenen beweglichen Anschlag 07 in axialer Richtung des Formzylinders 01 angreifende Kraft verschieben, was in der Fig. 7 jeweils durch einen parallel zur Traverse 27 gerichteten Doppelpfeil am beweglichen Anschlag 07 angedeutet ist, wodurch eine z. B. fertigungsbedingte Schwankung der sich in axialer Richtung des Formzylinders 01 erstreckenden Breite der dem Formzylinder 01 zuzuführenden Druckform 02 bedarfsgerecht ausgleichbar ist und ein Verklemmen der zuzuführenden Druckform 02 während ihrer Zuführung zum Formzylinder 01 vermieden werden kann. Trotz der Flexibilität, d. h. der Verschiebbarkeit des mit der Linearführung 33 verbundenen beweglichen Anschlags 07 erhält die dem Formzylinder 01 zuzuführende Druckform 02 aufgrund der federelastischen Lagerung dieses beweglichen Anschlags 07 eine ausreichende seitliche Stabilität für ihre registerhaltige Zuführung zum Formzylinder 01. Die zumindest eine in Relation zum Druckbild der Druckform 02 beschnittene Kante 14; 16 dieser Druckform 02 wird durch den federelastisch gelagerten beweglichen Anschlag 07 zuverlässig an dem hinsichtlich der Traverse 27 starren Anschlag 06 sowohl seitlich ausgerichtet als auch während des Zuführens dieser Druckform 02 an diesem starren Anschlag 06 geführt.In the example shown in FIGS. 4 to 6, a linear guide 33 is provided in the interior of the crossmember 27 on each bearing 31 of a stop 07 movable in the axial direction of the forme cylinder 01, the stop 07 movable in the axial direction of the forme cylinder 01 also being provided the movable part of the linear guide 33 is firmly connected. Stops 06 which are not designed to be movable in the axial direction of the forme cylinder 01 are fixedly connected to the crossmember 27 after their preselected axial positioning. The cross member 27 has at the positions of the movable stops 07 an opening 34, for. B. an elongated hole 34 directed in the axial direction of the forme cylinder 01 in order to connect the respective movable stop 07 to the linear guide 33 arranged in the interior of the cross member 27. The spring element 32 is arranged inside the linear guide 33 or on the end face on the linear guide 33 and is connected on one side to a holder 36 which is not movable with respect to the crossmember 27 (FIG. 7). The spring element 32 is, for. B. as a spring 32, in particular as a helical, cylindrical or as a plate-shaped spring 32, as a resilient body 32, for. B. a sufficiently soft rubber buffer, or as a z. B. formed from two interacting spring plates Parallθlogrammverschiθbung. A directed in the axial direction of the forme cylinder 01 spring travel of the spring element 32 is z. B. in the range of ± 0.5 mm to about 2 mm, preferably ± 0.5 mm to 1 mm. The spring element 32 is preferably biased. The linear guide 33 can be displaced within a maximum permissible displacement path predetermined by the spring travel of the spring element 32 by a force acting on the movable stop 07 connected to the linear guide 33 in the axial direction of the forme cylinder 01, which in each case in FIG. 7 by a parallel to the crosshead 27 directed double arrow on the movable stop 07 is indicated, whereby a z. B. production-related fluctuation of the in the axial direction of the forme cylinder 01 extending width of the form cylinder 01 to be fed printing form 02 can be compensated for as needed and jamming of the printing form 02 to be supplied during its feeding to the form cylinder 01 can be avoided. Despite the flexibility, ie the displaceability of the movable stop 07 connected to the linear guide 33, the printing form 02 to be fed to the forme cylinder 01 receives sufficient lateral stability due to the spring-elastic mounting of this movable stop 07 for its register-oriented feed to the forme cylinder 01. The at least one in relation to Print image of printing form 02 trimmed edge 14; 16 of this printing form 02 is reliably aligned by the spring-mounted movable stop 07 on the stop 06, which is rigid with respect to the crossmember 27, and is guided on this rigid stop 06 while this printing form 02 is being fed.
Zumindest der in axialer Richtung des Formzylinders 01 beweglich gelagerte Anschlag 07 kann an seiner der dem Formzylinder 01 zuzuführenden Druckform 02 zugewandten Seite für diese Druckform 02 eine Führungshilfe z. B. in Form einer in die Anschlagsf lache eingelassenen oder angeformten Nut aufweisen. Der in axialer Richtung des Formzylinders 01 beweglich gelagerte Anschlag 07 ist z. B. als ein lotrecht von der Traverse 27 abstehender Stift oder Steg ausgebildet, wohingegen der mit der Traverse 27 starr verbundene Anschlag 06 winkelförmig mit einer vergleichsweise großen, der dem Formzylinder 01 zuzuführenden Druckform 02 zugewandten Führungsfläche ausgebildet ist. Die dem Formzylinder 01 zuzuführende Druckform 02 wird während des Zuführvorgangs, d. h. während ihrer zum Formzylinder 01 gerichteten Transportbewegung, zwischen den Anschlägen 06; 07 in vorzugsweise gleitendem Berührungskontakt mit diesen Anschlägen 06; 07 hindurchgeführt. Dabei übt die Druckform 02 einerseits auf den in axialer Richtung des Formzylinders 01 beweglich gelagerten Anschlag 07 gegen das Federelement 32 eine Kraft aus, andererseits wird diese Druckform 02 in Reaktion auf ihre Abstützung an dem in axialer Richtung des Formzylinders 01 beweglich gelagerten Anschlag 07 während ihrer zum Formzylinder 01 gerichteten Transportbewegung gegen den für diese Druckform 02 wirksamen, hinsichtlich der Traverse 27 starr angeordneten Anschlag 06 gedrückt. Durch ein Zusammenwirken der mit den Anschlägen 06; 07 ausgebildeten Vorrichtung 04 zum Führen der Druckform 02 mit der registerhaltig hergestellten Druckform 02 kann eine zumindest seitenregistergenaue Positionierung der Druckform 02 auf der Mantelfläche eines Formzylinders 01 erreicht werden, weil durchgängig durch den gesamten Montagevorgang ein fester Bezug zwischen dem auf der Druckform 02 durch die Bebilderung aufgebrachten Druckbild und der mithilfe der Anschläge 06; 07 vorgenommenen Positionierung dieser Druckform 02 auf dem Formzylinder 01 bestehen bleibt. At least the stop 07, which is movably mounted in the axial direction of the forme cylinder 01, can be provided with a guide aid for this printing forme 02 on its side facing the forme cylinder 01. B. in the form of a recessed or molded into the stop surface. The stop 07 movably mounted in the axial direction of the forme cylinder 01 is e.g. B. formed as a perpendicular from the cross member 27 projecting pin or web, whereas the stop 06 rigidly connected to the cross member 27 is angularly formed with a comparatively large guide surface 02 to be fed to the forme cylinder 02. The printing form 02 to be fed to the forme cylinder 01 is between the stops 06; during the feeding process, ie during its transport movement directed towards the forme cylinder 01; 07 preferably in sliding contact with these stops 06; 07 passed through. On the one hand, the printing form 02 exerts a force on the stop 07 movably mounted in the axial direction of the forme cylinder 01 against the spring element 32, on the other hand, this printing form 02 becomes responsive to its support on the stop 07 which is movably supported in the axial direction of the forme cylinder 01 during its to the forme cylinder 01 directed transport movement against the effective for this printing form 02, rigidly arranged with respect to the cross member 27 stop 06. By cooperation of the stops 06; 07 designed device 04 for guiding the printing form 02 with the printing form 02 produced in register, the printing form 02 can be positioned at least on the register side on the lateral surface of a forme cylinder 01, because throughout the entire assembly process, a fixed relationship between that on the printing form 02 and the images applied printed image and with the help of the stops 06; 07 made positioning of this printing form 02 on the forme cylinder 01 remains.
