Abstract

The support device comprises a fixed bearing for the forme roller (4) wherein the bearing is set in the frame of the offset printer and is displaceable relative to the plate cylinder and the roller mounted in front of same. Separate adjusters (15-20) are provided for moving the forme roller opposite the plate cylinder and forward roller (3). Each adjuster runs radially to the plate cylinder of forward roller. The connection between the rotary axis of the plate cylinder and an axis (A1) of the forme roller is at right-angles to the connection of the axis with the rotary axis of the immersion roller.

Description

Die Erfindung betrifft eine Vorrichtung zur Lagerung einer Auftragwalze nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for mounting an applicator roller according to the preamble of claim 1.

In Feuchtwerken von Offsetdruckmaschinen sind Auftragwalzen vorgesehen, die der Zufuhr von Feuchtmittel auf einen eine Druckform tragenden Plattenzylinder dienen. Diese Auftragwalzen müssen mittels Stellmitteln gegenüber mit ihnen zusammenwirkenden Walzen und gegenüber dem Plattenzylinder an- und abstellbar sein. Durch die bisher bekannte Art und Weise der Gestaltung der Stellmittel ist es bedingt, daß bei der Rotation des Plattenzylinders Ungleichförmigkeiten in den Ablauf hineinkommen. Der Grund dafür ist, daß die Druckform auf dem Plattenzylinder festgespannt werden muß, wodurch sich an dessen Oberfläche mehr oder weniger große kanalförmige Unterbrechungen ergeben. Beim Überlaufen dieser Unterbrechungen in der Oberfläche des Plattenzylinders bzw. des sogenannten Zylinderkanals kann eine Auftragwalze also eine dieser Fehlstelle folgende Bewegung ausführen. Dadurch ergeben sich infolge der entstehenden Relativbewegungen zwischen den Walzen Unregelmäßigkeiten beim Transport des Feuchtmittels.In dampening units of offset printing machines, application rollers are provided, which are used to supply dampening solution to a plate cylinder carrying a printing form. These applicator rollers must be able to be turned on and off by means of adjusting means in relation to rollers which interact with them and in relation to the plate cylinder. Due to the previously known manner of designing the adjusting means, it is necessary for irregularities to get into the sequence when the plate cylinder rotates. The reason for this is that the printing form has to be clamped onto the plate cylinder, which results in more or less large channel-shaped interruptions on its surface. When these interruptions overflow in the surface of the plate cylinder or the so-called cylinder channel, an application roller can therefore execute a movement following this flaw. This results in irregularities in the transport of the dampening solution due to the resulting relative movements between the rollers.

Die Nachteile treten insbesondere bei konventionellen Walzenlagerungen auf. Hierbei ist eine Walze jeweils an beiden Seiten mit einem Walzenzapfen in einem Schwenkarm gelagert, der mittels eines Kurven- oder sonstigen Abstellgetriebes zu den Nachbarwalzen und dem Plattenzylinder hin bewegbar ist bzw. von diesen abstellbar ist. Das Kurvengetriebe wirkt gegen Federkraft. Das Abrollen der Auftragwalzen auf dem Plattenzylinder ist insbesondere durch die Anstellung über Federkraft nachteilig. Jede Radialbewegung der Auftragwalze beim Überlaufen des Zylinderkanals am Plattenzylinder wird durch die Anstellfedern in einer unregelmäßigen Bewegung zutage treten, auch wenn man durch Festanschläge versucht diese Bewegungen zu begrenzen.The disadvantages occur particularly with conventional roller bearings. Here, a roller is supported on both sides with a roller journal in a swivel arm, which can be moved by means of a cam or other shut-off gear to the adjacent rollers and the plate cylinder or can be removed from them. The cam mechanism works against spring force. The rolling of the application rollers on the plate cylinder is disadvantageous in particular due to the spring force. Every radial movement of the applicator roller when the cylinder channel overflows on the plate cylinder will show up in an irregular movement due to the adjusting springs, even if one tries to limit these movements by means of fixed stops.

Aufgabe der Erfindung ist es daher, eine Lagerung für eine Auftragwalze vorzusehen, die die geschilderten Nachteile vermeidet und eine exakte Einstellung der Auftragwalze sowohl zu dem Plattenzylinder als auch zu den Nachbarwalzen gestattet.The object of the invention is therefore to provide storage for an applicator roller avoids the disadvantages described and allows an exact adjustment of the application roller both to the plate cylinder and to the neighboring rollers.

Die Lösung der Aufgabe gestaltet sich nach den Merkmalen des Kennzeichens des Patentanspruches 1. Hierbei ist eine Lösung gefunden worden, die die An- und Abstellbewegung der Auftragwalze in optimaler Weise an die mit ihr zusammenwirkenden Walzen bzw. Zylinder gestattet. Weiterhin können die An- und Abstellbewegungen unabhängig voneinander zu dem Plattenzylinder und zu den Nachbarwalzen gesteuert werden. Außerdem ergibt sich durch die sozusagen gestellfeste Lagerung ein ruckfreier Betrieb auch beim Überlaufen von Fehlstellen im Plattenzylinder in Form von Zylinderkanälen. Weiterhin sind Betriebsweisen möglich, bei denen die Auftragwalze von den Nachbarwalzen abgestellt aber am Plattenzylinder angestellt bleibt.The solution to the problem is based on the features of the characterizing part of patent claim 1. A solution has been found which allows the on and off movement of the application roller in an optimal manner to the rollers or cylinders interacting with it. Furthermore, the on and off movements can be controlled independently of one another to the plate cylinder and to the neighboring rollers. In addition, the mounting, so to speak, which is fixed to the frame, results in jerk-free operation even when defects in the plate cylinder are overrun in the form of cylinder channels. Furthermore, modes of operation are possible in which the application roller is parked by the neighboring rollers but remains on the plate cylinder.

In Fig. 1 ist eine Übersicht eines Feuchtwerkes in einer Offsetdruckmaschine dargestellt. Das Feuchtwerk besteht aus einem Wasserkasten 1, einer Tauchwalze 2, einer daran angestellten Dosierwalze 3 und einer Auftragwalze 4, die zwischen der Tauchwalze 2 und einem Plattenzylinder 7 angeordnet ist. Die Auftragwalze 4 ist mittels einer Brückenwalze 5 mit einer ersten Farbwalze 6 verbunden. Die Farbwalze 6 und die Auftragwalze 4 sind an dem Plattenzylinder 7 angestellt. Der Plattenzylinder 7 weist an seinem Umfang in der Kontur Unterbrechungen auf, die der Aufspannung einer Druckform dienen. Bei Rotation des Plattenzylinders wird diese Unterbrechung in der Oberflächenkontur, der sogenannte Zylinderkanal auch die Position der Auftragwalze 4 und der Farbwalze 6 überlaufen. Um einer ungleichförmigen Bewegung der Auftragwalze 4 vorzubeugen, ist eine spezielle Walzenlagerung vorgesehen, wie sie in Fig. 2 im Schnitt gezeigt ist.1 shows an overview of a dampening unit in an offset printing press. The dampening unit consists of a water tank 1, an immersion roller 2, a metering roller 3 attached to it and an application roller 4 which is arranged between the immersion roller 2 and a plate cylinder 7. The application roller 4 is connected to a first inking roller 6 by means of a bridge roller 5. The inking roller 6 and the application roller 4 are employed on the plate cylinder 7. The plate cylinder 7 has on its circumference in the contour interruptions that serve to set up a printing form. When the plate cylinder rotates, this interruption in the surface contour, the so-called cylinder channel, also overflows the position of the application roller 4 and the inking roller 6. Around To prevent a non-uniform movement of the application roller 4, a special roller bearing is provided, as shown in section in FIG. 2.

In Fig. 2 ist für eine Walzenseite dargestellt, daß die Auftragwalze 4 mittels eines Kurzen Walzenzapfens 8 in einer Lagerschale 9 eingelegt ist. Die Lagerschale 9 ist entsprechend einem sogenannten Walzenschloß ausgebildet, in dem der Walzenzapfen 8 derart festlegbar ist, daß die Auftragwalze 4 allen Bewegungen der Lagerschale 9 folgt. Der Walzenzapfen 8 ist außerdem stirnseitig mit einer Ausnehmung 10 versehen. Beim Einsetzen der Auftragwalze 4 in die Lagerschale 9 übergreift die Ausnehmung 10 ein scheibenförmiges Antriebselement 11, das mit einer Antriebswelle 12 gekoppelt und von einem Antriebszahnrad 13 rotativ angetrieben wird. Die Auftragwalze 4 wird mittels der beschriebenen Vorrichtungen beim Einlegen in die Lagerschale 9 koaxial und unverrückbar mit der Antriebswelle 12 verbunden. Die Antriebswelle 12 wiederum ist innerhalb eines Gestellteiles 14, das mit der Druckmaschine fest verbunden ist, verstellbar gelagert. Dazu ist ein erster Stellexzenter 15 in dem Gestellteil 14 gelagert und innerhalb dieses ersten Stellexzenters 15 ist ein zweiter Stellexzenter 16 gelagert. Der Stellexzenter 16 wiederum weist eine Lagerung für die Antriebswelle 12 auf. An den Stellexzentern 15, 16 sind Stellhebel 17, 18 vorgesehen, die der Verdrehung der Stellexzenter 15, 16 dienen. An den Stellhebeln 17, 18 greifen, hier nur schematisch dargestellte, Stellstangen 19, 20 an. Somit wird der Stellexzenter 15 über den Stellhebel 17 von der Stellstange 19 gehalten bzw. bewegt. Der Stellexzenter 16 wird am Stellhebel 18 von der Stellstange 20 gehalten bzw. bewegt.2 shows for a roller side that the applicator roller 4 is inserted into a bearing shell 9 by means of a short roller pin 8. The bearing shell 9 is designed according to a so-called roller lock, in which the roll neck 8 can be fixed in such a way that the application roller 4 follows all movements of the bearing shell 9. The roll neck 8 is also provided on the end face with a recess 10. When the applicator roller 4 is inserted into the bearing shell 9, the recess 10 engages over a disk-shaped drive element 11 which is coupled to a drive shaft 12 and is rotatably driven by a drive gear 13. The application roller 4 is connected coaxially and immovably to the drive shaft 12 by means of the devices described when it is inserted into the bearing shell 9. The drive shaft 12 is in turn adjustably mounted within a frame part 14 which is firmly connected to the printing press. For this purpose, a first positioning eccentric 15 is mounted in the frame part 14 and a second positioning eccentric 16 is mounted within this first positioning eccentric 15. The eccentric 16 in turn has a bearing for the drive shaft 12. Adjusting levers 17, 18 are provided on the adjusting eccentrics 15, 16 and serve to rotate the adjusting eccentrics 15, 16. Actuating rods 19, 20 engage the adjusting levers 17, 18, shown only schematically here. The actuating eccentric 15 is thus held or moved by the actuating rod 19 via the actuating lever 17. The adjusting eccentric 16 is held or moved on the adjusting lever 18 by the adjusting rod 20.

In Fig. 3 ist die Anordnung der Stellexzenter 15, 16 zu ihrem Bewegungsantrieb näher dargestellt. Insbesondere ist die Zuordnung der Exzentrizitäten bzw. der Achslagen der Stellexzenter 15, 16 zur Antriebswelle 12 bzw. zur Achse der Auftragwalze 4 gezeigt. Hierbei ist zu beachten, daß für die Auftragwalze 4 eine Achse A1, für den Stellexzenter 15 eine Achse A2 und für den Stellexzenter 16 eine Achse A3 vorgesehen ist. Die Achsen A1, A2 und A3 stehen in einer bestimmten Beziehung zueinander, deren Ausführung und Zweck weiter unten näher erläutert wird. Auf die Stellexzenter 15, 16 wirken über eine einstellbare Drehverbindung 21 die Stellstangen 19, 20. Die Stellstangen 19, 20 werden mittels eines Antriebshebels 22 beaufschlagt. Am Antriebshebel 22 greift ein Pneumatikzylinder 23 an.In Fig. 3, the arrangement of the eccentric 15, 16 for their movement drive is shown in more detail. In particular, the assignment of the eccentricities or the axial positions of the positioning eccentrics 15, 16 to the drive shaft 12 or to the axis of the application roller 4 is shown. It should be noted here that an axis A1 is provided for the applicator roller 4, an axis A2 for the adjusting eccentric 15 and an axis A3 for the adjusting eccentric 16. The axes A1, A2 and A3 have a certain relationship to one another, the design and purpose of which are explained in more detail below. The adjusting rods 19, 20 act on the adjusting eccentrics 15, 16 via an adjustable rotary connection 21. The adjusting rods 19, 20 are acted upon by a drive lever 22. A pneumatic cylinder 23 engages on the drive lever 22.

Wie in Fig. 3 gezeigt liegen die Achsen A1, A2 und A3 nicht koaxial, sondern voneinander entfernt. Die Achsen A1 und A2 bilden eine Exzentrizität E1 der Auftragwalze 4 gegenüber dem Plattenzylinder 7. Die Achsen A2 und A3 bilden eine Exzentrizität E2 der Auftragwalze 4 gegenüber der Tauchwalze 2, wobei die Exzentrizität E2 sich im Abstand der Drehachsen der Stellexzenter 15, 16 darstellt. Die Abstände und die Orientierung sind so gewählt, daß die Stellmöglichkeiten möglichst ideale radiale Bewegungen ergeben. So ist die Achse A1 der Auftragwalze 4 zu der Achse A2 des Stellexezenters 15 so angeordnet, daß die dem Abstand entsprechende Exzentrizität E1 in etwa rechtwinklig zur Verbindung der Achse A1 der Auftragwalze 4 und der Achse des Plattenzylinders 7 liegt. Entsprechend liegt die Achse A3 des Stellexzenters 16 zu der Achse A2 des Stellexzenters 15 um die Exzentrizität E2 versetzt etwa rechtwinklig zur Orientierung der Achsverbindung zwischen Auftragwalze 4 und Tauchwalze 2. Damit ist sichergestellt, daß sich die jeweilige Exzentrizität E1 bzw. E2 beim An- bzw. Ab- bzw. Einstellen annähernd radial an der zugeordneten Stellebene auswirkt.As shown in Fig. 3, the axes A1, A2 and A3 are not coaxial, but apart. The axes A1 and A2 form an eccentricity E1 of the application roller 4 with respect to the plate cylinder 7. The axes A2 and A3 form an eccentricity E2 of the application roller 4 with respect to the immersion roller 2, the eccentricity E2 being the distance between the axes of rotation of the adjusting eccentrics 15, 16. The distances and the orientation are chosen so that the adjustment possibilities result in ideal radial movements. Thus, the axis A1 of the application roller 4 to the axis A2 of the eccentric 15 is arranged such that the eccentricity E1 corresponding to the distance is approximately perpendicular to the connection of the axis A1 of the application roller 4 and the axis of the plate cylinder 7. Correspondingly, the axis A3 of the positioning eccentric 16 is offset from the axis A2 of the positioning eccentric 15 by the eccentricity E2 approximately at right angles to the orientation of the axis connection between the applicator roller 4 and the dipping roller 2. This ensures that the respective eccentricity E1 or E2 during the approach or Removal or adjustment affects approximately radially at the assigned setting level.

In Fig. 4 ist noch einmal die Verbindung zwischen dem Antriebshebel 22 und den Stellhebeln 17, 18 gezeigt. Die Stellstangen 19, 20 sind innerhalb des Antriebshebels 22 drehbar mittels Kontermuttern gesichert. Sie werden in den Stellhebeln 17, 18 in Gleitstücken 24, 25 eingeschraubt. Bei einer Bewegung des Antriebshebels 22 sind so auch Ausgleichsbewegungen der Stellstangen 19, 20 gegenüber sowohl dem Antriebshebel 22 als auch gegenüber den Stellhebeln 17, 18 möglich.4 shows the connection between the drive lever 22 and the actuating levers 17, 18 again. The adjusting rods 19, 20 are rotatably secured within the drive lever 22 by means of lock nuts. They are screwed into slide levers 24, 25 in the adjusting levers 17, 18. When the drive lever 22 moves, compensating movements of the actuating rods 19, 20 relative to both the drive lever 22 and the actuating levers 17, 18 are also possible.

In Fig. 5 ist die Lagebeziehung der Auftragwalze 4 einerseits zum Plattenzylinder 7 bzw. andererseits zu der Tauchwalze 2 aufgezeigt. Werbei ist dargestellt, daß die Auftragwalze 4 in zwei Anstellrichtungen A und B zu positionierbar ist. Die Anstellrichtungen A und B liegen jeweils radial zur benachbarten Oberfläche des Plattenzylinders 7 bzw. der Tauchwalze 2. Eine An- bzw. Abstellbewegung der Auftragwalze 4 soll also gleichzeitig möglichst radial zum Plattenzylinder 7 und auch radial zur Tauchwalze 2 erfolgen. Die Anstellrichtung A entspricht der Verbindung zwischen der Achse A1 der Auftragwalze 4 und der Achse der Tauchwalze 2. Die Anstellrichtung B entspricht der Verbindung zwischen der Achse A1 der Auftragwalze 4 und der Achse des Plattenzylinders 7. Durch die Überlagerung der Anstellrichtungen A und B beim gleichzeitigen Anstellen an beide Oberflächen ist eine radiale Anstellung nicht in gleicher Weise möglich, da eine kombinierte An-/Abstellbewegung angestrebt wird.5 shows the positional relationship of the application roller 4 on the one hand to the plate cylinder 7 and on the other hand to the dipping roller 2. It is shown that the applicator roller 4 can be positioned in two directions of adjustment A and B. The adjustment directions A and B are each radially to the adjacent surface of the plate cylinder 7 or the plunger roller 2. An on or off movement of the applicator roller 4 should therefore take place at the same time as radially as possible to the plate cylinder 7 and also radially to the plunger roller 2. The adjustment direction A corresponds to the connection between the axis A1 of the applicator roller 4 and the axis of the plunger roller 2. The adjustment direction B corresponds to the connection between the axis A1 of the applicator roller 4 and the axis of the plate cylinder 7. By overlapping the adjustment directions A and B at the same time Starting on both surfaces radial adjustment is not possible in the same way, since a combined on / off movement is sought.

Zur Verbesserung der Einstellmöglichkeiten und zur Optimierung der Stellauswirkungen kann außerdem vorgesehen sein, eine Verstellmöglichkeit des Plattenzylinders 7 so anzuordnen, daß die Bewegung tangential zur Auftragwalze 4 erfolgt. Dazu sollte auch die Anordnung der Achsverbindungen zwischen Plattenzylinder 7 und Auftragwalze 4, sowie zwischen Auftragwalze 4 und Tauchwalze 2 rechtwinklig zueinander ausgeführt sein. Beispielsweise bei Änderung des wirksamen Umfangs am Plattenzylinder 7 durch Unterlegen der Druckform ist eine Abstandsänderung zum benachbarten Druckwerkszylinder erforderlich, um die sogenannte Druckbeistellung dh. den Anstelldruck neu zu justieren. Bei dieser Verstellung soll aber die Einstellung der Auftragwalze nicht beeinflußt werden, da sie ja selbständig vorgenommen wird. Durch die Anordnung der Stellebenen in rechtem Winkel zueinander wird dieses Problem behoben. Dabei wird die Beistellung der Auftragwalze 4 durch die tangentiale Verschiebung nur minimal beeinflußt. Außerdem ist keine Nachführung der Auftragwalze 4 bei größeren Stellwegen erforderlich, die aufgrund der fehlenden Anfederung der Auftragwalze 4 sonst erforderlich sein könnte.In order to improve the setting options and to optimize the adjustment effects, provision can also be made to arrange an adjustment possibility of the plate cylinder 7 in such a way that the movement is tangential to the application roller 4. For this purpose, the arrangement of the axis connections between plate cylinder 7 and applicator roller 4, and between applicator roller 4 and plunger roller 2 should be carried out at right angles to one another. For example, when changing the effective circumference of the plate cylinder 7 by placing the printing form underneath, a change in the distance to the adjacent printing unit cylinder is required in order to provide the so-called printing. to readjust the starting pressure. With this adjustment, however, the setting of the application roller should not be influenced, since it is carried out independently. This problem is solved by arranging the positioning planes at right angles to one another. The provision of the applicator roller 4 is only minimally influenced by the tangential displacement. In addition, no tracking of the applicator roller 4 is required for larger travel ranges, which could otherwise be necessary due to the lack of springing of the applicator roller 4.

In der Ausführungsform nach der Erfindung sind die beiden Stellexzenter 15, 16 so angeordnet, daß wie oben beschrieben je einer der Stellexzenter 15, 16 genau der optimalen Abstellbewegung zur Tauchwalze 2 bzw. zum Plattenzylinder 7 entspricht. Durch die gemeinsame Bewegung beim An- und Abstellen der Auftragwalze 4 ergibt sich ein optimierter Mittelwert für die Stellbewegung beim Verstellen der Auftragwalze 4. Die unabhängige Positionierung der Auftragwalze 4 relativ zum Plattenzylinder 7 bzw. zur Tauchwalze 2 erfolgt in optimaler Weise über die Stellstangen 19, 20, indem diese in den Gleitstücken 24, 25 ein- oder ausgeschraubt werden. Damit wird die Grundposition der Auftragwalze 4 festgelegt. Damit kann die Einstellung sowohl annähernd radial zum Plattenzylinder 7, als auch zur Tauchwalze 2 ausgeführt werden. Die An- und Abstellbewegung ist eine optimale Kombination aus den Anstellbewegungen relativ zu den beiden Einzelelementen Plattenzylinder 7 bzw. Tauchwalze 2.In the embodiment according to the invention, the two adjusting eccentrics 15, 16 are arranged in such a way that, as described above, one of the adjusting eccentrics 15, 16 corresponds exactly to the optimal stopping movement to the dipping roller 2 or to the plate cylinder 7. The joint movement when the applicator roller 4 is turned on and off results in an optimized mean value for the actuating movement when adjusting the applicator roller 4. The independent positioning of the applicator roller 4 relative to the plate cylinder 7 or the immersion roller 2 takes place in an optimal manner via the actuating rods 19, 20 by screwing them into or out of the sliders 24, 25. The basic position of the application roller 4 is thus determined. The setting can thus be carried out both approximately radially with respect to the plate cylinder 7 and with the immersion roller 2. The switch-on and switch-off movement is an optimal combination of the switch-on movements relative to the two individual elements plate cylinder 7 and plunger roller 2.

In Fig. 6 ist die abgestellte Position der Auftragwalze 4 dargestellt und die Abstellbewegung bzw. Anstellbewegung in Form eines Doppelpfeiles aufgezeigt. Die kombinierte Stellrichtung aus der Bewegung der beiden Stellexzenter 15, 16 weist sozusagen in den Spalt zwischen Plattenzylinder 7 und Tauchwalze 2.In Fig. 6 the parked position of the applicator roller 4 is shown and the parking movement or positioning movement is shown in the form of a double arrow. The combined Setting direction from the movement of the two adjusting eccentrics 15, 16 points, so to speak, into the gap between plate cylinder 7 and plunger roller 2.

In Fig. 7 ist eine besondere Positionierung der Auftragwalze 4 gezeigt. Es kann in bestimmten Fällen erforderlich sein, die Auftragwalze 4 nur zum Plattenzylinder 7 und zur Farbwalze 6 über die Brückenwalze 5 hin anzustellen. Dies ist durch die getrennte Positionierung der beiden Stellexzenter 15, 16 möglich. Hierzu wird der Stellexzenter 16, der die Anstellung zur Tauchwalze 2 bewirkt soweit verdreht, daß in der angestellten Position in Folge des Bewegung des Pneumatikzylinders 23 keine Berührung mehr zwischen der Auftragwalze 4 und der Tauchwalze 2 gegeben ist. In dieser Postition kann die Auftragwalze 4 als zusätzliche Farbauftragwalze verwendet werden. Dies ist beispielsweise bei der Verwendung von sogenannten wasserlosen Druckformen in der Offsetdruckmaschine nützlich.7 shows a special positioning of the applicator roller 4. In certain cases it may be necessary to apply the application roller 4 only to the plate cylinder 7 and to the inking roller 6 via the bridge roller 5. This is possible through the separate positioning of the two adjusting eccentrics 15, 16. For this purpose, the adjusting eccentric 16, which causes the adjustment to the dipping roller 2, is rotated to such an extent that there is no longer any contact between the application roller 4 and the dipping roller 2 in the employed position as a result of the movement of the pneumatic cylinder 23. In this position, the applicator roller 4 can be used as an additional inking roller. This is useful, for example, when using so-called waterless printing forms in the offset printing press.

Die Anwendung der speziellen Lagerung der Auftragwalze 4 mittels der beiden Stellexzenter 15, 16 ist nicht auf die gezeigte Ausführungsform beschränkt. Wesentliche ist die bezüglich der benachbarten Funktionselemente starre Lagerung und die gegenüber den verschiedenen Funktionselementen unabhängige Einstellbarkeit. Diese Merkmale sind auch mittels anderer technischer Mittel ausführbar.The application of the special mounting of the application roller 4 by means of the two adjusting eccentrics 15, 16 is not limited to the embodiment shown. What is essential is the rigid support with respect to the neighboring functional elements and the adjustability that is independent of the various functional elements. These features can also be implemented using other technical means.

Die Vorrichtung ist an allen Auftragwerken in Druckmaschinen einsetzbar, in denen eine Auftragwalze zu einem Formzylinder und einer eine Flüssigkeit zuliefernden Walze anzustellen ist. Hier kommen auch Farbwerke und Lackierwerke in Betracht. Weiterhin ist ein Einsatz in anderen Beschichtungseinrichtungen mit Walzen vorstellbar.The device can be used on all applicators in printing presses in which an applicator roller is to be used to form a forme cylinder and a roller supplying a liquid. Inking units and coating units are also considered here. Use in other coating devices with rollers is also conceivable.
