Abstract

An inking unit for a printing machine including a duct consisting of a plurality of adjacent duct segments mounted individually on the duct roller of the machine wherein each duct segment forms a carrier for at least some of the ink metering elements. The mounting of the duct segments on the duct roller is such that it substantially eliminates the hydrodynamic pressure forces occurring at the duct roller and the ink metering elements during operation. As a result, the duct roller deflection and the influence thereof on the metering gap are greatly reduced so that readjustment of the ink metering elements with respect to one another during operation can be dispensed with.

Description

Die Erfindung betrifft ein Farbwerk für eine Druckmaschine mit einer Farbkastenwalze, einem an die Farbkastenwalze anstellbaren Farbkasten mit mehreren in ihrem Abstand zur Farbkastenwalze unabhängig voneinander einstellbaren Farbdosierelementen.The invention relates to an inking unit for a printing press with an ink fountain roller, an ink fountain that can be adjusted to the ink fountain roller, with a plurality of ink metering elements that can be adjusted independently of one another in terms of their distance from the ink fountain roller.

Bei Farbwerken dieser Art werden zur zonenweisen Dosierung des auf der Farbkastenwalze erzeugten Farbfilms, die einzelnen Farbdosierelemente in ihrem Abstand zur Farbkastenwalze so eingestellt, daß ein Dosierspalt entsteht, der die gewünschte Farbmenge durchfließen läßt. Hierbei treten je nach Größe des Dosierspalts zum Teil sehr hohe hydrodynamische Druckkräfte zwischen den Farbdosierelementen und der Farbkastenwalze auf. Diese Druckkräfte erreichen in Zonen mit geringstem Farbfluß einen um Zehnerpotenzen höheren Wert als in Zonen mit großem Farbfluß. Jede andere Einstellung der Farbdosierelemente hat daher eine andere Belastung und Durchbiegung der Farbkastenwalze über die gesamte Maschinenbreite zur Folge, so daß ein genaues Einregeln der einzelnen Farbdosierelemente zeitraubend und schwierig ist.In inking units of this type, the individual ink metering elements are adjusted in their distance from the ink fountain roller for zone-by-zone metering of the ink film produced on the ink fountain roller so that a metering gap is created which allows the desired amount of ink to flow through. Depending on the size of the metering gap, very high hydrodynamic pressure forces sometimes occur between the ink metering elements and the ink fountain roller. In zones with the lowest ink flow, these compressive forces reach a value ten powers higher than in zones with a large ink flow. Any other setting of the ink metering elements therefore results in a different load and deflection of the ink fountain roller over the entire machine width, so that precise adjustment of the individual ink metering elements is time-consuming and difficult.

Bei einem bekannten Farbwerk der angegebenen Art (DE-OS 2 723 845) weist ein die Farbdosierelemente tragender Halteblock des sich über die gesamte Druckmaschinenbreite erstreckenden Farbkastens einen Anschlag auf, der sich an die Farbkastenwalze anlegt, wenn der Halteblock an die Farbkastenwalze angestellt ist. Die Anlageflächen des Anschlags haben dabei eine Krümmung, die derjenigen der Farbkastenwalze entspricht. Mit dieser bekannten Vorrichtung soll eine direkte Einstellung des Halteblocks und der Farbdosierelemente gegenüber der Farbkastenwalze erreicht und Einflüsse durch die Lagerung der Farbkastenwalze und des Farbkastens im Maschinenrahmen vermieden werden. Die Durchbiegung der Farbkastenwalze kann mit dieser Vorrichtung jedoch nicht erfaßt und ausgeglichen werden.In a known inking unit of the type specified (DE-OS 2 723 845), a holding block of the inking elements carrying the ink metering elements, which extends across the entire width of the printing press, has a stop which bears against the inking roller when the holding block is engaged against the inking roller. The contact surfaces of the stop have a curvature that corresponds to that of the ink fountain roller. With this known device, a direct setting of the holding block and the ink metering elements with respect to the ink fountain roller is to be achieved and influences by the storage of the ink fountain roller and the ink fountain in the machine frame are to be avoided. The deflection of the ink fountain roller can not be detected and compensated for with this device.

Der Erfindung liegt die Aufgabe zugrunde, ein Farbwerk der eingangs genannten Art zu schaffen, bei dem die Einstellung der Farbdosierelemente von der Durchbiegung der Farbkastenwalze nicht mehr nachteilig beeinträchtigt wird.The invention has for its object to provide an inking unit of the type mentioned, in which the setting of the ink metering elements is no longer adversely affected by the deflection of the ink fountain roller.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Farbkasten aus mehreren, nebeneinanderliegenden Kastensegmenten besteht, die einzeln unmittelbar an der Farbkastenwalze gelagert sind, wobei jedes Kastensegment einen Träger für einen Teil der Farbdosierelemente bildet. Durch diese Aufteilung des Farbkastens in einzelne Kastensegmente, die aufgrund ihrer Lagerung der Durchbiegung der Farbkastenwalze folgen können, wird der Einfluß der Durchbiegung auf den Dosierspalt so erheblich verringert, daß ein Nachjustieren der Farbdosierelemente nicht mehr erforderlich ist.This object is achieved in that the ink fountain consists of several juxtaposed box segments, which are individually mounted directly on the ink fountain roller, each box segment forming a carrier for part of the ink metering elements. Due to this division of the ink fountain into individual fountain segments, which can follow the deflection of the ink fountain roller due to their mounting, the influence of the deflection on the metering gap is reduced so considerably that readjustment of the ink metering elements is no longer necessary.

In einer vorteilhaften Weiterbildung der Erfindung ist die Lagerung der Kastensegmente an der Farbkastenwalze so ausgebildet, daß sie die im Betrieb auftretenden hydrodynamischen Druckkräfte aufnimmt. Diese Weiterbildung der Erfindung hat den Vorteil, daß sich die Durchbiegung der Farbkastenwalze erheblich verringert, weil sich die wirksame Biegelänge der Farbkastenwalze auf den wesentlich geringeren Abstand der Lagerung der Kastensegmente vermindert. Da die Größe der Eigendurchbiegung von der vierten Potenz der Biegelänge bestimmt wird, wird durch diese erfindungsgemäße Maßnahme bereits bei der Aufteilung des Farbkastens in vier Kastensegmente eine so erhebliche Verringerung der Durchbiegung der Farbkastenwalze erzielt, daß sie bei der Einstellung der Farbdosierelemente vernachlässigt werden kann.In an advantageous development of the invention, the bearing of the box segments on the ink fountain roller is designed such that it absorbs the hydrodynamic pressure forces that occur during operation. This development of the invention has the advantage that the deflection of the ink fountain roller is significantly reduced because the effective bending length of the ink fountain roller is reduced to the much smaller distance between the storage of the box segments. Since the magnitude of the inherent deflection is determined by the fourth power of the bending length, this measure according to the invention already results in a considerable reduction in the deflection of the ink fountain roller when the ink fountain is divided into four fountain segments that it can be neglected when setting the ink metering elements.

Zur Lagerung der Kastensegmente ist nach einem weiteren Vorschlag der Erfindung ein Trägerkasten vorgesehen, der an der Farbkastenwalze gelagert ist und an dem die einzelnen Kastensegmente begrenzt schwenkbar befestigt sind. Hierdurch wird eine Lagerung geschaffen, die eine einfache Montage der Kastensegmente zu Wartungs- oder Reparaturzwecken ermöglicht.To support the box segments, a carrier box is provided according to a further proposal of the invention, which is mounted on the ink fountain roller and to which the individual box segments are fastened so as to be pivotable to a limited extent. This creates a storage that enables easy assembly of the box segments for maintenance or repair purposes.

Um eine genaue Ausrichtung der Kastensegmente parallel zur Farbkastenwalze zu ermöglichen, kann erfindungsgemäß die Lagerung der Kastensegmente an dem Trägerkasten quer zu ihrer Schwenkachse pendelnd ausgeführt sein.In order to enable a precise alignment of the box segments parallel to the ink fountain roller, the mounting of the box segments on the carrier box can be carried out transversely to their pivot axis.

Vorzugsweise trägt die Farbkastenwalze jeweils den seitlichen Enden der Kastensegmente benachbarte Lagerringe, an denen der Trägerkasten angeflanscht ist und an die sich die Kastensegmente mit einstellbaren Anschlägen anlegen. Hierdurch wird eine verschleißarme Lagerung geschaffen, die ein genaues Einstellen der Kastensegmente zur Farbkastenwalze ermöglicht. Dabei ist es vorteilhaft, wenn die Lagerringe in Nuten in der Farbkastenwalze eingebettet sind und ihr Außendurchmesser im Bereich des Hebers und der Farbdosierelemente nicht größer ist, als der Außendurchmesser der Farbkastenwalze. Auf diese Weise kann ein Heber mit einer durchgehenden Heberwalze ungehindert an die Farbkastenwalze heranbewegt werden. Im Bereich der Farbdosierelemente vereinfacht diese Ausbildung der Lagerringe die Abdichtung der Kastensegmente gegenüber der Farbkastenwalze.The ink fountain roller preferably carries bearing rings adjacent to the lateral ends of the barrel segments, to which the carrier box is flanged and to which the barrel segments bear with adjustable stops. This creates a low-wear bearing that enables the box segments to be precisely adjusted to the ink fountain roller. It is advantageous if the bearing rings are embedded in grooves in the ink fountain roller and their outer diameter in the area of the lifter and the ink metering elements is not greater than the outer diameter of the ink fountain roller. In this way, a lifter with a continuous lifter roller can be moved freely to the ink fountain roller. In the area of ink metering elements, this design of the bearing rings simplifies the sealing of the box segments from the ink box roller.

Eine besonders einfache Ausgestaltung der Farbkastenwalze besteht erfindungsgemäß darin, daß die Farbkastenwalze aus einer durchgehenden Welle und mehreren auf die Welle aufgeschobenen und drehfest mit ihr verbundenen Rohrsegmenten besteht, wobei jeweils ein Rohrsegment mit den Farbdosierelementen eines Kastensegments zusammenwirkt und daß jeweils auf beiden Seiten der Rohrsegmente ein Lagerring lose auf der Welle gelagert ist. Das axiale Spiel zwischen den Rohrsegmenten und den Lagerringen wird dabei vorteilhaft durch eine mit einem Ende der Welle verschraubte Spannmutter eingestellt, die mit einem festen Wellenbund am anderen Ende der Welle zusammenwirkt.A particularly simple embodiment of the ink fountain roller according to the invention is that the ink fountain roller consists of a continuous shaft and a plurality of tube segments pushed onto the shaft and connected to it in a rotationally fixed manner, one tube segment interacting with the ink metering elements of one tube segment and one on both sides of the tube segments Bearing ring is loosely mounted on the shaft. The axial play between the tube segments and the bearing rings is advantageously adjusted by a clamping nut screwed to one end of the shaft, which cooperates with a fixed shaft collar at the other end of the shaft.

Nach einem weiteren Vorschlag der Erfindung kann die axiale Fixierung der Rohrsegmente auf der Welle auch derart erfolgen, daß ein in der Mitte der Welle liegendes Rohrsegment axial unverschiebbar mit der Welle verbunden ist und daß zwischen den beiden äußeren Lagerringen und diesen benachbarten, an den Wellenenden befestigten Anschlagelementen Druckfedern eingespannt sind. Hierdurch wird erreicht, daß die einzelnen Rohrsegmente und die Lagerringe axial spielfrei gegeneinander gedrückt werden, wobei die Festlegung auf der Welle durch das in der Mitte liegende Rohrsegment erfolgt. Diese Ausgestaltung hat den Vorteil, daß eine Wärmeausdehnung der Rohrsegmente elastisch aufgenommen werden kann. Weiterhin hat diese Ausgestaltung den Vorteil, daß die Verschiebung der Rohrsegmente und der mit ihnen über die Lagerringe verbundenen Kastensegmente in axialer Richtung, die durch die Wärmeausdehnung der Rohrsegmente hervorgerufen wird, höchstens halb so groß ist, wie die Gesamtwärmeausdehnung der durch alle Rohrsegmente gebildeten Farbkastenwalze.According to a further proposal of the invention, the axial fixing of the pipe segments on the shaft can also be carried out in such a way that a pipe segment lying in the middle of the shaft is axially immovably connected to the shaft and that between the two outer bearing rings and those adjacent to them, fastened to the shaft ends Stop elements compression springs are clamped. This ensures that the individual pipe segments and the bearing rings are pressed axially against one another without play, the fixing on the shaft being carried out by the pipe segment lying in the middle. This configuration has the advantage that thermal expansion of the tube segments can be absorbed elastically. Furthermore, this embodiment has the advantage that the displacement of the tube segments and the box segments connected to them via the bearing rings in the axial direction, which is caused by the thermal expansion of the tube segments, is at most half as large as the total thermal expansion of the ink fountain roller formed by all tube segments.

Die Lagerung der Kastensegmente ist nach einem weiteren Vorschlag der Erfindung vorteilhaft elastisch ausgebildet. Hierzu sind zwischen den Kastensegmenten und dem Trägerkasten Federn eingespannt, durch die die Kastensegmente mit den einstellbaren Anschlägen an ihren seitlichen Enden gegen die Lagerringe auf der Farbkastenwalze gedrückt werden. Hierdurch können die Kastensegmente Bewegungen oder Verformungen der Farbkastenwalze folgen, ohne daß es zu Zwangskräften und zu einer Änderung ihres Abstands zur Farbkastenwatze kommt. Die Vorspannung der Federung ist dabei so ausgelegt, daß sie größer ist als die maximal auftretenden hydrodynamischen Druckkräfte an den Farbdosierelementen.The storage of the box segments is advantageously designed to be elastic according to a further proposal of the invention. For this purpose, springs are clamped between the box segments and the carrier box, by means of which the box segments with the adjustable stops at their lateral ends are pressed against the bearing rings on the ink fountain roller. As a result, the box segments can follow movements or deformations of the ink fountain roller without there being any constraining forces and a change in their distance from the ink fountain roller. The preload of the suspension is designed so that it is greater than the maximum hydrodynamic pressure forces that occur on the ink metering elements.

Die Anschläge werden vorteilhaft durch Einstellschrauben gebildet, die etwa in der Ebene der Farbdosierelemente liegen. Die Einstellschrauben an den benachbarten Enden zweier Kastensegmente liegen dabei vorzugsweise in Umfangsrichtung gegeneinander versetzt an dem gleichen Lagerring an. Hierdurch wird eine sehr gedrängte Bauweise erzielt, wodurch die farbfreien Zonen auf der Farbkastenwalze im Bereich der Lagerringe klein bleiben.The stops are advantageously formed by adjusting screws which lie approximately in the plane of the ink metering elements. The adjusting screws on the adjacent ends of two box segments are preferably offset from one another in the circumferential direction on the same bearing ring. This results in a very compact design, which means that the ink-free zones on the ink fountain roller remain small in the area of the bearing rings.

Zur Befestigung des Trägerkastens am Seitengestell der Druckmaschine ist erfindungsgemäß eine parallel zur Farbkastenwalze verlaufende Traverse vorgesehen, durch die der Trägerkasten in seiner Lage zur Farbkastenwalze fixiert ist. Nach einem weiteren Vorschlag der Erfindung sind die Rohrsegmente der Farbkastenwalze, die Kastensegmente und entsprechende Abschnitte des Trägerkastens als aufeinander abgestimmte Baumodule ausgebildet, die zur Bildung unterschiedlicher Farbwerksbreiten in beliebiger Anzahl aneinandergereiht werden können. Mit dieser Ausgestaltung besteht die Möglichkeit das erfindungsgemäße Farbwerk bei einem Minimum an unterschiedlichen Bauteilen den verschiedenen Maschinenbreiten anzupassen.To fasten the carrier box to the side frame of the printing machine, a traverse running parallel to the ink fountain roller is provided according to the invention, by means of which the carrier box is fixed in its position relative to the ink fountain roller. According to a further proposal of the invention, the tube segments of the ink fountain roller, the box segments and corresponding sections of the carrier box are designed as coordinated building modules which can be strung together in any number to form different inking unit widths. With this configuration, it is possible to adapt the inking unit according to the invention to the different machine widths with a minimum of different components.

Bei dem in Fig. 1 dargestellten Farbwerk besteht die Farbkastenwalze 1 aus einer durchgehenden Welle 2, die mit ihren beiden Enden in den Seitengestellen 3 einer Druckmaschine gelagert ist. Auf die Welle 2 sind in abwechselnder Reihenfolge Lagerringe 4 und Rohrsegmente 5 aufgeschoben derart, daß den Seitengestellen 3 jeweils ein Lagerring 4 benachbart ist. Die Rohrsegmente 5 sind durch Mitnehmerzapfen 6 mit der Welle 2 verbunden. In axialer Richtung sind die Lagerringe 4 und die Rohrsegmente 5 durch einen an der Welle 2 befestigten Ringbund 7 und eine mit der Welle 2 verschraubte Spannmutter 8 gehalten. Mit der Spannmutter 8 kann das an den Lagerringen 4 erforderliche axiale Bewegungsspiel eingestellt werden. Der Außendurchmesser der Lagerringe 4 und der Rohrsegmente 5 ist etwa gleich.In the inking unit shown in Fig. 1, the ink fountain roller 1 consists of a continuous shaft 2, which is supported with its two ends in the side frames 3 of a printing press. On the shaft 2 bearing rings 4 and tube segments 5 are pushed in alternating order such that the side frames 3 each have a bearing ring 4 adjacent. The pipe segments 5 are connected to the shaft 2 by driver pins 6. In the axial direction, the bearing rings 4 and the tubular segments 5 are held by an annular collar 7 fastened to the shaft 2 and a clamping nut 8 screwed to the shaft 2. With the clamping nut 8, the axial movement play required on the bearing rings 4 can be set. The outer diameter of the bearing rings 4 and the tube segments 5 is approximately the same.

An den Lagerringen 4 sind Stege 9 eines Trägerkastens 10 mit Schrauben befestigt. Der Trägerkasten 10 ist weiterhin durch eine Traverse 11 gehalten, die sich parallel zur Farbkastenwalze 1 erstreckt und in den Seitengestellen 3 befestigt ist. Zwischen zwei Stegen 9 befindet sich jeweils ein Kastensegment 12, das an den Stegen 9 in der Nähe der Traverse 11 schwenkbar gelagert ist. Der dargestellte Trägerkasten 10 weist fünf Stege 9 auf und kann daher vier Kastensegmente 12 aufnehmen. Aus Vereinfachungsgründen sind in der Zeichnung jedoch nur zwei Kastensegmente 12 dargestellt.On the bearing rings 4 webs 9 of a carrier box 10 are fastened with screws. The carrier box 10 is further held by a crossmember 11 which extends parallel to the ink fountain roller 1 and is fastened in the side frames 3. Between two webs 9 there is a box segment 12, which is pivotably mounted on the webs 9 in the vicinity of the crossbar 11. The carrier box 10 shown has five webs 9 and can therefore accommodate four box segments 12. For reasons of simplification, however, only two box segments 12 are shown in the drawing.

Jedes Kastensegment 12 trägt als Schieber 13 ausgebildete Farbdosierelemente und Stellvorrichtungen 14, mit denen der Abstand der einzelnen Schieber 13 zur Farbkastenwalze 1 unabhängig voneinander einstellbar ist. Die Stellvorrichtungen 14 können von Hand oder motorisch verstellt werden. Um die Schieber 13 in einem vorgegebenen Abstand zur Farbkastenwalze 1 zu halten sind die Kastensegmente 12 über Einstellschrauben 15, 16 unmittelbar an den Lagerringen 4 abgestützt. Die Anlage der Einstellschrauben 15, 16 an den Lagerringen 4 wird dabei durch Druckfedern 17 gewährleistet, die zwischen dem Trägerkasten 10 und den Kastensegmenten 12 eingespannt sind.Each box segment 12 carries ink metering elements and adjusting devices 14 designed as slides 13, with which the distance of the individual sliders 13 from the ink fountain roller 1 can be set independently of one another. The adjusting devices 14 can be adjusted by hand or by motor. In order to keep the slider 13 at a predetermined distance from the ink fountain roller 1, the box segments 12 are supported directly on the bearing rings 4 by means of adjusting screws 15, 16. The engagement of the adjusting screws 15, 16 on the bearing rings 4 is ensured by compression springs 17 which are clamped between the carrier box 10 and the box segments 12.

Die Einstellschrauben 14, 15 befinden sich an den seitlichen Enden der Kastensegmente 12 und liegen etwa in der gleichen Ebene wie die Schieber 13. Wie aus Fig. 3 zu sehen, liegen die Einstellschrauben 15 und die Einstellschrauben 16 in Umfangsrichtung gegeneinander versetzt an dem Lagerring 4 an, so daß an einem Lagerring 4 die benachbarten Enden zweier Kastensegmente 12 abgestützt sein können.The adjusting screws 14, 15 are located on the lateral ends of the box segments 12 and lie approximately in the same plane as the slides 13. As can be seen from FIG. 3, the adjusting screws 15 and the adjusting screws are located 16 offset in the circumferential direction against each other on the bearing ring 4, so that the adjacent ends of two box segments 12 can be supported on a bearing ring 4.

Bei Inbetriebnahme der Druckmaschine werden zunächst die Kastensegmente mit Hilfe der Einstellschrauben 15, 16 in eine Nullstellung gebracht, in der die Stirnkanten der Schieber 13 parallel an dem jeweils benachbarten Rohrsegment 5 der Farbkastenwalze 1 anliegen. Die Verstellung der Einstellschrauben 15, 16 kann dabei von Hand oder motorisch erfolgen. Anschließend werden die einzelnen Schieber 13 entsprechend dem gewünschten Farbprofil auf den erforderlichen Abstand zur Farbkastenwalze eingestellt. Die richtige Einstellung wird dabei ohne Schwierigkeiten nach vorher rechnerisch oder empirisch ermittelten Einstellwerten erreicht, da die Durchbiegung der Farbkastenwalze in den Abschnitten zwischen den Lagerringen 4 so gering ist, daß sie die Einstellung nicht beeinflußt. Auch Verformungen der Farbkastenwalze 1 durch Änderung der Betriebstemperatur und Lageänderungen der Farbkastenwalze 1 im Bereich ihrer Lagerung in den Seitengestellen bleiben auf den jeweils eingestellten Farbspalt ohne Einfluß, da die einzelnen Kastensegmente von den Druckfedern 17 ständig an die Lagerringe 4 angedrückt werden und den Bewegungen der Farbkastenwalze 1 folgen.When the printing press is started up, the box segments are first brought into a zero position with the aid of the adjusting screws 15, 16, in which the end edges of the slides 13 abut in parallel on the respectively adjacent tube segment 5 of the ink fountain roller 1. The adjustment screws 15, 16 can be adjusted by hand or by motor. The individual slides 13 are then set to the required distance from the ink fountain roller in accordance with the desired color profile. The correct setting is achieved without difficulty according to previously calculated or empirically determined setting values, since the deflection of the ink fountain roller in the sections between the bearing rings 4 is so small that it does not influence the setting. Deformations of the ink fountain roller 1 by changing the operating temperature and changes in position of the ink fountain roller 1 in the area of their storage in the side frames remain without influence on the ink gap set in each case, since the individual box segments are constantly pressed by the compression springs 17 against the bearing rings 4 and the movements of the ink fountain roller 1 follow.

Der auf der Farbkastenwalze 1 erzeugte Farbfilm wird in üblicher Weise von einer Heberwalze 18 auf eine nicht dargestellte Verreibwalze übertragen. Bei der Verreibung und Verteilung der Farbe im Farbwerk werden die im Bereich der Lagerringe 4 vorhandenen farbfreien Zonen egalisiert.The ink film produced on the ink fountain roller 1 is transferred in the usual way from a lifting roller 18 to a distribution roller, not shown. When the ink is rubbed and distributed in the inking unit, the ink-free zones in the area of the bearing rings 4 are equalized.

Durch den Aufbau des Farbwerks aus einzelnen Bausegmenten wird eine Modulbauweise erzielt, die mit geringem baulichen Aufwand eine Anpassung an unterschiedlich breite Druckmaschinen ermöglicht. Die Breite der einzelnen Baumodule wird dabei so festgelegt, daß jeweils durch Hinzufügung von einem oder mehreren Baumodulen die jeweils gewünschte Maschinenbreite erreicht wird. In Fig. 4 ist eine solche Anordnung veranschaulicht. Das Farbwerk besteht dort aus einem linken Endmodul 20, drei gleichen Zwischenmodulen 21 und einem rechten Endmodul 22. Wird eine andere Baubreite benötigt, so werden Zwischenmodule 21 hinzugefügt oder entfernt.By building the inking unit from individual building segments, a modular construction is achieved that allows adaptation to printing machines of different widths with little construction effort. The width of the individual building modules is determined so that the desired machine width is achieved by adding one or more building modules. Such an arrangement is illustrated in FIG. 4. The inking unit there consists of a left end module 20, three identical intermediate modules 21 and a right end module 22. If a different width is required, intermediate modules 21 are added or removed.

In Fig. 4 ist weiterhin eine axiale Lagerung der Lagerringe 4,4' und der Rohrsegmente 5 auf der Welle 2 gezeigt, bei der an beiden Enden der Welle angeordnete Druckfedern 24 die Lagerringe 4,4' und die Rohrsegmente 5 in axialer Richtung spielfrei gegeneinander drücken. Die Druckfedern 24 sind dabei zwischen den äußeren Lagerringen 4' und mit den Enden der Welle 2 verschraubten Schraubmuttern 23 eingespannt. Durch Verstellen der Spannmuttern 23 kann die Vorspannung der Federn 24 verändert werden. Zur genauen Lagefixierung der Lagerringe 4,4' und der Rohrsegmente 5 ist dabei das mittlere Rohrsegment 5 axial unverschiebbar mit der Welle 2 verbunden. Diese Ausbildung hat den Vorteil, daß Wärmeausdehnungen von den Druckfedern 24 elastisch aufgenommen werden können und nicht zu einem Verspannen der Rohrsegmente gegenüber den Lagerringen führen. Weiterhin wird durch die Mittenfixierung eine gleichmäßige Verteilung der Wärmedehnung nach beiden Seiten erreicht, so daß die maximale Verschiebung insbesondere der äußeren Lagerringe 4' gegenüber dem Maschinenständer nur halb so groß ist wie die durch Erwärmung hervorgerufene Längeausdehnung.4 also shows an axial mounting of the bearing rings 4, 4 'and the tube segments 5 on the shaft 2, in which the compression springs 24 arranged on both ends of the shaft, the bearing rings 4, 4' and the tube segments 5 in the axial direction without play against one another to press. The compression springs 24 are clamped between the outer bearing rings 4 'and screw nuts 23 screwed to the ends of the shaft 2. By adjusting the clamping nuts 23, the bias of the springs 24 can be changed. In order to fix the position of the bearing rings 4, 4 'and the tube segments 5 in an exact manner, the middle tube segment 5 is axially immovably connected to the shaft 2. This design has the advantage that thermal expansions can be absorbed elastically by the compression springs 24 and do not lead to the tube segments being braced relative to the bearing rings. Furthermore, a uniform distribution of the thermal expansion to both sides is achieved by the center fixation, so that the maximum displacement, in particular of the outer bearing rings 4 ', is only half as large as the longitudinal expansion caused by heating.
