Abstract

During register control of a cylinder of a printing unit, a drive causes the cylinder to shift in the axial position thereof by a designated extent in order to adjust the side register. The shift in the axial position of the cylinder ensues in conjunction with a change in the rotation angle position of a drive of the cylinder.

Durch die DE 34 09 194 A1 ist eine Registerregelung bekannt, wobei eine Relativbewegung zweier Zylinder in Umfangsrichtung mittels einer axialen Relativbewegung zweier schrägverzahnter Zahnräder erfolgt. Eine Verstellung des Seitenregisters, ohne dass gleichzeitig das Umfangsregister verstellt wird, erfolgt durch Relativbewegung zweier zusätzlicher gerade verzahnter Zahnräder.By DE 34 09 194 A1 a register control is known, wherein a Relative movement of two cylinders in the circumferential direction by means of an axial Relative movement of two helical gears takes place. An adjustment of the Page register, without simultaneously the circumferential register is adjusted by Relative movement of two additional straight toothed gears.

In der DE 196 03 663 A1 ist ein Formzylinder und der mit diesem zusammen wirkende Übertragungszylinder parallel mittels eines Motors antreibbar. Über ein Getriebe ist der Formzylinder axial verstellbar. Das auf dem Zapfen des Formzylinders angeordnete schrägverzahnte Stimrad ist zwecks Umfangsregisterverstellung axial auf dem Zapfen bewegbar angeordnet.In DE 196 03 663 A1 is a form of cylinder and acting together with this Transfer cylinder drivable in parallel by means of a motor. About a gear is the Form cylinder axially adjustable. The arranged on the journal of the forme cylinder helical spur gear is for the purpose of circumferential register adjustment axially on the pin movably arranged.

In der DE 37 12 702 A1 ist ein sechs Zylinder aufweisendes Druckwerk offenbart, dessen Zylinder alle über Schrägverzahnung miteinander in Antriebsverbindung stehen. Der rotatorische Antrieb der Zylinder erfolgt über ein Antriebszahnrad auf einen der sechs Zylinder. Eine seitliche Verstellung des Formzylinders, und eine daraus resultierende Änderung im Umfangsregister, wird kompensiert, indem die Position des Formzylinders festgestellt, und darauf hin der Übenragungszylinder in die gleiche Richtung verschoben wird.In DE 37 12 702 A1 discloses a six cylinder exhibiting printing unit, whose Cylinders are all in drive connection with each other via helical gearing. Of the Rotational drive of the cylinder via a drive gear on one of the six Cylinder. A lateral adjustment of the forme cylinder, and a resulting Change in the circumferential register, is compensated by the position of the forme cylinder determined, and then the Überstragungszylinder moved in the same direction becomes.

Die US 37 17 092 A offenbart ein Druckwerk, dessen Zylinder über eine Schrägverzahnung von einem Hauptantrieb aus antreibbar sind. Zur Regelung des Selten- und des Umfangsregisters sind je Druckwerk zwei zusätzliche Antriebe vorgesehen. Bei Seitenregisterverstellung wird gleichzeitig eine Korrektur des durch die Schrägverzahnung verursachten Fehlers mittels des Antriebes für das Umfangsregister durchgeführt.The US 37 17 092 A discloses a printing unit whose cylinder over a Helical teeth are driven by a main drive. To regulate the Rare and circumferential registers are two additional drives per printing unit intended. When Seitenregisterverstellung is at the same time a correction of the Helix caused error by means of the drive for the circumferential register carried out.

Die JP 11 25 46 54 A zeigt ein Verfahren und eine Vorrichtung zur Registerregelung, wobei ein Signal zur Seitenregistereinstellung einer Registersteuerung und einer Recheneinheit zugeführt wird. Die Seitenregisterregelung wird nun durch die Registersteuerung vorgenommen. Die Recheneinheit ermittelt anhand des Signals einen Korrekturwert für das Umfangsregister und führt diesen der Antriebssteuerung des Antriebsmotors zu.JP 11 25 46 54 A shows a method and a device for register control, wherein a signal to the page register setting a register control and a Arithmetic unit is supplied. The page register control is now controlled by the Register control made. The arithmetic unit determines a signal based on the signal Correction value for the circumferential register and guides it to the drive control of the Drive motor too.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Registerregelung zu schaffen.The invention has for its object to provide a method and an apparatus for Register regulation.

Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1, 2, 8 oder 10 gelöst.The object is achieved by the features of claims 1, 2, 8 or 10th solved.

Die mit der Erfindung erzielbaren Vorteile für gekoppelte Zylinder bestehen insbesondere darin, dass ein geringer mechanischer Aufwand, z. B. bei der Anzahl der zu bewegenden Zylinder oder der Anzahl von Zahnradverbindungen, erforderlich ist, und somit auch möglichst wenig Quellen für ein die Druckqualität negativ beeinflussendes Zahnradspiel vorliegen.The achievable with the present invention advantages for coupled cylinders are in particular in that a low mechanical effort, z. B. in the number of moving Cylinder or the number of gear connections, and thus also as few sources for a printing quality negatively influencing gear play available.

Auch weist die vorliegende Registerregelung ein hohes Maß an Flexibilität auf, da die elektronische Regelung nahezu frei programmierbar und nicht allein durch Mechanik vorgegeben ist.Also, the present register regime has a high degree of flexibility as the Electronic control almost freely programmable and not only by mechanics is predetermined.

Die Regelung gewährleistet eine einfache, schnelle und robuste Korrektur des Umfangsregisters in Verbindung mit der Regelung des Seitenregisters, ohne dass hierfür zusätzliche Antriebe oder aufwendige Getriebe zur Korrektur des Umfangsregisters erforderlich sind.The control ensures a simple, fast and robust correction of the Circular register in connection with the regulation of the page register, without this additional drives or complex gears to correct the circumferential register required are.

Von besonderem Vorteil im Hinblick auf die Belastbarkeit und die Festigkeit von Zahnrädern ist es, dass der Antriebszug vollständig mittels Schrägverzahnung erfolgen kann. Der Antriebszug ist trotz Schrägverzahnung in einer Flucht bzw. Antriebsebene anordenbar. Auch dies trägt zur Vereinfachung der Mechanik und zur Raumersparnis bei. Of particular advantage in terms of resilience and strength of It is gearwheels that the drive train is completely made by helical gearing can. The drive train is in spite of helical gearing in an alignment or drive plane arranged. This also contributes to the simplification of the mechanics and to the space savings.

Der Antrieb kann mittels eines Ritzels vom Antriebsmotor auf ein Zahnrad, oder aber nahezu koaxial zum Zylinder auf dessen Zapfen direkt, ggf. unter Zwischenschaltens eines Planetengetriebes, erfolgen.The drive can by means of a pinion from the drive motor to a gear, or almost coaxial to the cylinder on the pin directly, possibly with interposition a planetary gear, done.

Da die Änderungen von Umfangsregister und Seitenregister im Zusammenspiel der beiden Motoren, des Antriebsmotors und des Motors für die axiale Verstellung, erfolgt, kann der Antrieb mittels des Antriebsmotors wahlweise an einem der beiden gemeinsam angetriebenen Zylinder, z. B. am Formzylinder oder am Übertragungszylinder, erfolgen.Since the changes of the circumferential register and the page register are interlinked with each other both motors, the drive motor and the motor for the axial adjustment, takes place, can the drive by means of the drive motor either at one of the two together driven cylinder, z. B. on the forme cylinder or on the transfer cylinder done.

In vorteilhafter Ausführung weist der gemeinsame Antrieb der beiden Zylinder, z. B. zwecks Relativbewegung in Umfangsrichtung, keine formschlüssige Antriebsverbindung zu einem weiteren Formzylinder, beispielsweise eines Formzylinders eines weiteren Druckwerkes, auf.In an advantageous embodiment, the common drive of the two cylinders, z. B. for the purpose of relative movement in the circumferential direction, no positive drive connection to a further forme cylinder, for example a forme cylinder of another Printing unit, on.

Ein Druckwerk einer Druckmaschine, z. B. einer Rotationsdruckmaschine, weist einen ersten Zylinder 01, z. B. einen Formzylinder 01, und einen mit diesem in Druck-An-Stellung zusammen wirkenden zweiten Zylinder 02, z. B. einen Übertragungszylinder 02, auf. Der Übertragungszylinder 02 bildet mit einem nicht dargestellten dritten Zylinder, z. B. einem zweiten Übertragungszytinder eines zweiten Druckwerks oder einem Gegendruckzylinder eine Druckstelle. Ein dem Formzylinder 01 zugeordnetes Farbwerk und ggf. ein Feuchtwerk sind nicht dargestellt.A printing unit of a printing press, z. B. a rotary printing machine, has a first cylinder 01, z. B. a forme cylinder 01, and one with this in Pressure-on-position cooperating second cylinder 02, z. B. one Transfer cylinder 02, on. The transfer cylinder 02 does not form with one illustrated third cylinder, z. B. a second Übertragungszytinder a second Printing unit or an impression cylinder a pressure point. A forme cylinder 01 associated inking unit and possibly a dampening unit are not shown.

Der zweite Zylinder 02 kann, beispielsweise für Druckwerke aus dem Hochdruck, auch als Gegendruckzylinder 02 ausgeführt sein, der in diesem Fall mit dem ersten Formzylinder 01 eine Druckstelle bildet.The second cylinder 02 can, for example, for printing units from the high pressure, as well Counter-pressure cylinder 02 be executed, in this case with the first forme cylinder 01 forms a pressure point.

Die beiden Zylinder 01; 02 weisen stimseitig jeweils Zapfen 03; 04 auf und stehen durch zwei an Zapfen 03; 04 drehfest und axial unverschiebbar angeordneten, miteinander kämmenden Zahnrädern 06; 07 (07 strichliert dargestellt) in Antriebsverbindung. Die Zahnräder 06; 07 sind in vorteilhafter Ausführung zwecks Festigkeit und Belastbarkeit der Antriebsverbindung mit Schrägverzahnung ausgeführt. Die beiden Zylinder 01, 02 weisen einen gemeinsamen Antrieb 08, z. B. einen Antriebsmotor 08 für den rotatorischen Antrieb der Zylinder 01; 02 auf, welcher beispielsweise als Elektromotor ausgebildet und bezüglich seiner Drehwinkellage regelbar ist.The two cylinders 01; 02 have end-side each journal 03; 04 up and stand by two pins on 03; 04 rotationally fixed and arranged axially immovable, with each other meshing gears 06; 07 (07 dashed lines) in drive connection. The Gears 06; 07 are in an advantageous embodiment for the purpose of strength and resilience of Drive connection with helical teeth executed. The two cylinders 01, 02 point a common drive 08, z. B. a drive motor 08 for the rotary drive the cylinder 01; 02, which, for example, designed as an electric motor and is adjustable with respect to its angular position.

Einer der Zylinder 01; 02, im Beispiel der Formzylinder 01, weist auf einer seiner Stirnseiten eine nicht näher beschriebene Einrichtung zum axialen Verschieben des Formzylinders 01 um einen Betrag ± ΔL auf. Dies kann mittels eines hydraulisch oder motorisch betätigbaren Antriebs 09 erfolgen, welcher jedoch eine definierte Bewegung und einen Rückschluss über den zurückgelegten Weg oder die jeweilige Position, ggf. mittels zusätzlicher Sensoren, zulässt.One of the cylinders 01; 02, in the example of the forme cylinder 01, points to one of his End faces a device not described in detail for the axial displacement of the Form cylinder 01 by an amount ± .DELTA.L on. This can be done by means of a hydraulic or motor actuated drive 09 done, which, however, a defined movement and a conclusion about the distance traveled or the respective position, if necessary by means of additional sensors, allows.

In den Ausführungsbeispielen wird diese Einrichtung durch den Motor 09 dargestellt, mittels welchem beispielsweise über eine nicht dargestellte Gewindespindel oder in sonstiger Weise der Formzylinder 01 axial bewegbar ist. Die aktuelle Lage des Formzylinders 01 ist beispielsweise mittels eines Drehpotentiometers ablesbar, welches in Wirkverbindung mit der nicht dargestellten Motorwelle steht. Der Motor 09 kann auch bezüglich seiner Drehwinkellage regelbar ausgeführt sein, so dass beispielsweise über die Anzahl der Umdrehungen und die momentane Winkellage eine eindeutige Information über die axiale Lage des Formzylinders 01 möglich ist.In the exemplary embodiments, this device is represented by the motor 09, by means of which, for example, via a threaded spindle, not shown, or in otherwise, the forme cylinder 01 is axially movable. The current situation of the Form cylinder 01 can be read for example by means of a rotary potentiometer, which in Active connection with the motor shaft, not shown, is. The engine 09 can also be made adjustable with respect to its angular position, so that, for example, over the number of revolutions and the instantaneous angular position unambiguous information about the axial position of the forme cylinder 01 is possible.

Im ersten Ausführungsbeispiel (Fig. 1) erfolgt der Antrieb der beiden Zylinder 01; 02 vom Antriebsmotor 08 auf den Formzylinder 01, wobei das mit dem Formzylinder 01 verbundene Zahnrad 06 mit einem ebenfalls schrägverzahnten Antriebsrad 11, z. B. einem Zahnrad 11 wie beispielsweise mit einem Ritzel 11 des Antriebsmotors 08, kämmt. Der Antriebsmotor 08 und das mit einer Welle 12 des Antriebsmotors 08 verbundene Ritzel 11 sind hierbei gestellfest angeordnet, der Formzylinder 01 mit dem Zahnrad 06 jedoch in axialer Richtung bewegbar gelagert. Der Antrieb vom Antriebsmotor 08 auf das Zahnrad 06 kann u. U. auch über ein Getriebe erfolgen.In the first embodiment (Figure 1), the drive of the two cylinders 01; 02 from Drive motor 08 on the forme cylinder 01, wherein the with the forme cylinder 01 connected gear 06 with a likewise helical drive wheel 11, z. B. a gear 11 such as with a pinion 11 of the drive motor 08, meshes. The drive motor 08 and connected to a shaft 12 of the drive motor 08 Pinion 11 are arranged fixed to the frame, the form cylinder 01 with the gear 06th but movably mounted in the axial direction. The drive from the drive motor 08 on the Gear 06 can u. U. also be done via a transmission.

Beide Antriebe 08; 09, der Antriebsmotor 08 sowie der Motor 09, sind mit einer Regeleinrichtung 13 verbunden, welche dem Antriebsmotor 08 eine Drehwinkellage  bzw. eine Änderung in der Drehwinkellage Δ und dem Motor 09 eine Position L bzw. den Betrag ΔL für die axiale Verschiebung vorgeben kann. Die Regeleinrichtung 13 kann einer Antriebssteuerung 14 nach- oder vorgeschaltet, in eine Maschinensteuerung integriert oder auch mit einem Leitstand verbunden sein.Both drives 08; 09, the drive motor 08 and the motor 09, are with a Control device 13 connected, which the drive motor 08 a rotational angle position  or a change in the rotational angle position Δ and the motor 09 a position L or the Amount ΔL can specify for the axial displacement. The control device 13 can one Drive control 14 downstream or upstream, integrated in a machine control or be connected to a control room.

Soll nun eine Verstellung des Seitenregisters, d. h. eine axiale Verschiebung des Formzylinders 01 um einen Betrag ΔL erfolgen, ohne dass gleichzeitig eine Änderung des Umfangsregisters resultiert, so wird in der Regeleinrichtung 13 ein zu diesem Betrag ΔL korrespondierender Wert für die erforderliche Änderung in der Drehwinkellage Δ des Antriebsmotors 08 ermittelt. Diese Änderung in der Drehwinkellage Δ wirkt der durch die Relativbewegung der schrägverzahnten Zahnräder 06; 07; 11 bedingten Änderung im Umfangsrichtung entgegen und kompensiert diese. Es erfolgt gleichzeitig eine axiale Bewegung des Formzylinders 01 um den Betrag ΔL mittels des Motors 09 und eine die in Umfangsrichtung durch die Schrägverzahnung bedingte Verstellung kompensierende Änderung der Drehwinkellage Δ des Antriebsmotors 08. If now an adjustment of the page register, d. H. an axial displacement of the Form cylinder 01 by an amount .DELTA.L be done without simultaneously changing the Peripheral register results, so is in the control device 13 to this amount .DELTA.L corresponding value for the required change in the angular position Δ of Drive motor 08 determined. This change in the rotational angle position Δ acts through the Relative movement of the helical gears 06; 07; 11 conditional change in the Circumferential direction and compensates for this. There is simultaneously an axial Movement of the forme cylinder 01 by the amount .DELTA.L by means of the motor 09 and one in the Circumferential direction compensated by the helical toothing conditional adjustment Change of the rotational angle position Δ of the drive motor 08.

Eine Korrektur des Formzylinders 01 relativ zu einem nicht dargestellten weiteren Druckwerk oder einer Verarbeitungsstation in Umfangsrichtung wird mittels der Änderung in der Drehwinkellage Δ des Antriebsmotors 08 vorgenommen.A correction of the forme cylinder 01 relative to a further, not shown Printing unit or a processing station in the circumferential direction is by means of the change made in the rotational position Δ of the drive motor 08.

Vorteilhaft in der Ausführung nach Fig. 1 ist es, dass der Antriebszug in einer Flucht ausgeführt werden kann und dass eine Seitenregisterregelung mit Korrektur des Umfangsregisters über die Drehwinkellage  erfolgt, ohne dass eine Änderung einer Drehwinkellage des mit der zu bedruckenden Bahn zusammenwirkenden Übertragungszylinders resultiert. Unter Änderung der Drehwinkellage  ist eine relative Drehwinkellage  zu verstehen, und nicht die betriebsbedingte Winkelgeschwindigkeit. Die relative Änderung wird der betriebsbedingten Winkelgeschwindigkeit bzw. Winkellage z. B. überlagert.It is advantageous in the embodiment according to FIG. 1 that the drive train is in alignment can be executed and that a page register control with correction of the Circumferential register on the angular position  without a change of a Angular position of the cooperating with the web to be printed Transfer cylinder results. By changing the angular position  is a relative Angular position  to understand, and not the operational angular velocity. The relative change is the operational angular velocity or angular position z. B. superimposed.

In einem zweiten Ausführungsbeispiel (Fig. 2) erfolgt der Antrieb der beiden Zylinder 01; 02 am Übertragungszylinder 02, beispielsweise koaxial zu einer Rotationsachse des Übertragungszylinders 02 an dessen Zapfen 04.In a second embodiment (FIG. 2), the drive of the two cylinders 01 takes place; 02 on the transfer cylinder 02, for example, coaxial with a rotational axis of the Transfer cylinder 02 at the pin 04.

Vom Zahnrad 06 kann beispielsweise unter Beibehaltung eines eindeutigen Momentenflusses, und damit mit verringerter Gefahr von Zahnflankenwechseln, auf ein nicht dargestelltes Farbwerk und/oder Feuchtwerk abgetrieben werden.From gear 06, for example, while maintaining a unique Moment flow, and thus with reduced risk of tooth flank changes, on a Not shown inking and / or dampening be driven off.

Eine axiale Verschiebung des Formzylinders 01 um einen Betrag ΔL erfolgt hier, indem in der Regeleinrichtung 13 wieder der dem Betrag ΔL entsprechende Wert für die Änderung in der Drehwinkellage Δ ermittelt wird, und die beiden Werte an die Antriebe 08; 09, den Antriebsmotor 08 und den Motor 09, gegeben werden. Eine reine Änderung im Umfangsregister, d. h. in der Drehwinkellage  des Formzylinders 01 relativ zu einem nicht dargestellten weiteren Druckwerk oder einer Verarbeitungsstation, erfolgt allein über die Änderung in der Drehwinkellage Δ des Antriebsmotors 08. An axial displacement of the forme cylinder 01 by an amount ΔL takes place here in the controller 13 again corresponding to the amount .DELTA.L value for the change is determined in the rotational angle position Δ, and the two values to the drives 08; 09, the Drive motor 08 and the motor 09, are given. A pure change in the Circumferential register, d. H. in the rotational angular position  of the forme cylinder 01 relative to a not shown further printing unit or a processing station, takes place solely on the change in the rotational position Δ of the drive motor 08th

Die Ausführung nach Fig. 2 ist für den Fall besonders vorteilhaft, wenn z. B. ein Farbwerk über denselben Antriebsmotor 08 angetrieben, aber ein eindeutiger Momentenfluß erreicht werden soll.The embodiment of FIG. 2 is particularly advantageous for the case when z. B. an inking unit driven via the same drive motor 08, but a unique moment flow should be achieved.

Von großem Vorteil ist die Registerregelung auch für einen unabhängig vom Übertragungszylinder 02 durch einen eigenen Antriebsmotor 08 angetriebenen Formzylinder 01 (die Unabhängigkeit ist in Fig. 1 durch die strichlierte Darstellung des Zahnrades 07 symbolisiert). Die über eine hinterlegte Abhängigkeit zwischen der Änderung in axialer Richtung ΔL und der erforderlichen Änderung in der Drehwinkellage Δ ausgeführte Korrektur ist schnell und robust. Ein ggf. erforderliches Nachregeln im Rahmen der idR vorhandenen Regelung für das Umfangsregister kann ohne große Ausschläge und ohne ein längeres Nachschwingen erfolgen. Im Idealfall tritt kein Nachregeln bzw. Nachschwingen im Umfangsregister auf.Of great advantage is the register control also for an independent of Transfer cylinder 02 driven by its own drive motor 08 Form cylinder 01 (the independence is shown in Fig. 1 by the dashed line of the Gear 07 symbolizes). The over a deposit dependency between the Change in the axial direction ΔL and the required change in the angular position Δ executed correction is fast and robust. A possibly necessary readjustment in The usually existing regulation for the circumferential register can be used without large Rashes and without a long ringing done. Ideally, no occurs Readjustment or reverberation in the scope register.

In der Regelung des Umfangsregisters in Verbindung mit einer Änderung in der axialen Lage des Formzylinders 01 kann auch dessen, z. B. mittels Sensoren, ermittelte Lage L selbst oder eine über den Antrieb 09 abgreifbare Information über die Lage L als Wert für die Korrektur einfließen.In the regulation of the circumferential register in conjunction with a change in the axial Location of the forme cylinder 01 can also be, z. B. by means of sensors, determined location L itself or via the drive 09 can be tapped information about the position L as a value for incorporate the correction.

Die Ankopplung des Antriebsmotors 08 aus dem ersten Ausführungsbeispiel (Fig. 1) kann auch auf das zweite Ausführungsbeispiel (Fig. 2) übertragen werden und umgekehrt. Wird im ersten Ausführungsbeispiel (Fig. 1) jedoch der Formzylinder 01 koaxial angetrieben, so ist eine in der Länge veränderbare, nicht dargestellte Kupplung zwischen Antriebsmotor 08 und Formzylinder 01 anzuordnen, welche den axialen Weg bei Änderung der axialen Lage ΔL des Formzylinders 01 aufnimmt.The coupling of the drive motor 08 from the first embodiment (FIG. 1) can be transferred to the second embodiment (Fig. 2) and vice versa. Becomes in the first embodiment (FIG. 1), however, the forme cylinder 01 is driven coaxially, then is a variable in length, not shown coupling between the drive motor 08 and form cylinder 01 to order, which the axial path when changing the axial Position .DELTA.L of the forme cylinder 01 receives.

Der Antriebsverbund der beiden Ausführungsbeispiele (Fig. 1 und 2), aus den beiden Zylindern 01; 02 und ggf. dem Farb- und u. U. einem Feuchtwerk, weist keine formschlüssige Antriebsverbindung zu einem ggf. in der Druckmaschine angeordneten weiteren Formzylinder auf. Er weist in vorteilhafter Ausführung auch keine formschlüssige Antriebsverbindung mit einem zusammenwirkenden Druckwerk oder einem Gegendruckzylinder auf.The drive network of the two embodiments (FIGS. 1 and 2), of the two Cylinders 01; 02 and possibly the color and u. U. a dampening unit, has none positive drive connection to an optionally arranged in the printing press on another form cylinder. He has in an advantageous embodiment, no positive Drive connection with a cooperating printing unit or a Impression cylinder on.

In allen Ausführungsbeispielen erfolgt zwecks Einstellung des Seitenregisters eine Änderung einer axialen Lage des Formzylinders 01 um einen Betrag ΔL in Verbindung mit einer korrespondierenden Änderung in der Drehwinkellage Δ des Antriebes 08.In all embodiments, for the purpose of setting the page register is a Change of an axial position of the forme cylinder 01 by an amount ΔL in conjunction with a corresponding change in the rotational position Δ of the drive 08th

Vorteilhaft ist die Regelung des Seitenregisters mittels der beiden Antriebe 08; 09 gleichzeitig und innerhalb gleicher Zeitspannen und, z. B. für den Fall linearer Zusammenhänge, ggf. gleicher Zeitrampen. Die Werte für die Zusammenhänge zwischen Δ und ΔL können als Funktion Δ(ΔL) oder als Wertetabelle in der Regeleinrichtung 13 hinterlegt sein. Anhand dieser Funktion bzw. Wertetabelle können dann auch Zeitrampen für die beiden möglichst synchron auszuführenden Bewegungen durch die Antriebe 08; 09 ermittelt bzw. hinterlegt werden. Die Werte bzw. die Funktion können z. B. über die wirksamen Radienverhältnisse und die Schräge der Verzahnung am Formzylinder definiert sein. Der Zusammenhang wird in jedem Fall entsprechend der Schrägverzahnung vorgegeben, was ein störungsfreies Drucken ermöglicht. Ein Nachregeln des Umfangsregisters im Anschluß an eine Seitenregisterregelung kann so vermieden oder zumindest stark reduziert werden.Advantageously, the regulation of the side register by means of the two drives 08; 09 simultaneously and within equal time periods and, for. B. in the case of linear Connections, if necessary equal time ramps. The values for the relationships between Δ and ΔL can be used as a function Δ (ΔL) or as a value table in the control device 13 be deposited. Using this function or table of values, time slots can also be used for the two possible movements to be performed synchronously by the drives 08; 09 be determined or deposited. The values or the function can, for. B. over the effective radii ratios and the slope of the teeth on the forme cylinder be defined. The connection is in each case according to the Beveling predetermined, which allows trouble-free printing. One Readjustment of the circumferential register following a page register control may be so be avoided or at least greatly reduced.

Es kann auch direkt die Information über die Lage L bzw. Lageänderung ΔL in der Regeleinrichtung 13 dazu herangezogen werden, die Drehwinkellage  entsprechend zu ändern. Auch in diesem Fall wird die Korrektur nicht erst durch die Messung eines auftretenden Fehlers, sondern in direktem Zusammenhang mit der axialen Lage L bzw. deren Änderung ΔL herbeigeführt. It can also directly the information about the position L or change in position .DELTA.L in the Regulating device 13 are used to the rotational angle position  accordingly to change. Even in this case, the correction is not only by the measurement of a occurring error, but in direct connection with the axial position L or whose change ΔL brought about.
