Description

Die Erfindung betrifft eine in einem axial verlaufenden Spannkanal eines Zylinders angeordnete Vorrichtung zum Befestigen einer biegsamen Platte auf dem Umfang des Zylinders zum Befestigen einer Lack- oder Druckplatte oder eines Gummituchs auf dem Umfang eines Lack- oder Gummituchzylinders einer Lackiermaschine mit am Anfang und am Ende der Platte ausgebildeten, in den Spannkanal weisenden Kanten, wobei mit einer Anfangskantenbefestigungseinrichtung die Anfangskante der Platte sowie mit einer Endkantenbefestigungseinrichtung die Endkante der Platte gehalten ist.The invention relates to an axially extending Clamping channel of a cylinder arranged device to attach a flexible plate the circumference of the cylinder for fastening a varnish or printing plate or a rubber blanket on the circumference of a lacquer or blanket cylinder a painting machine with in the beginning and formed at the end of the plate, in the Edges pointing to the tensioning channel, with an initial edge fastening device the start edge the plate and with an end edge fastening device held the end edge of the plate is.

Aus der deutschen Offenlegungsschrift 40 11 303 ist eine Vorrichtung der eingangs genannten Art bekannt. Der Anfang und das Ende eines auf einen Zylinder aufgespannten Gummituchs werden zwischen einer Unter- und einer Oberschiene geklemmt. Zum Spannen des Gummituchs werden Ober- und Unterschiene gemeinsam radial nach innen in den Zylinder hineinverlagert. Die Befestigungseinrichtung für das Gummituch erstreckt sich über einen relativ langen Umfangsbereich des Zylinders, so daß ein entsprechender Abschnitt des Gesamtumfangs nicht als Abwälzlänge zur Verfügung steht. From German published patent application 40 11 303 a device of the type mentioned is known. The beginning and the end of one on a cylinder stretched blanket are between a Bottom and top rail clamped. To the Tensioning the rubber blanket becomes the top and bottom rails together radially inwards into the cylinder in shifts. The fastening device for the rubber blanket extends over a relative long circumferential area of the cylinder, so that a corresponding section of the total scope is not is available as gear length.

Das französische Patent mit der Veröffentlichungsnummer 2 082 373 zeigt ein L-Profil, das auf der einen Seite des Plattenendes angeordnet ist, und eine Leiste, die auf der anderen Seite am Plattenende positioniert wird. Beide Teile werden unter Zwischenschaltung der Platte miteinander vernietet.The French patent with the publication number 2 082 373 shows an L-profile on the one side of the plate end is arranged, and a bar on the other side at the plate end is positioned. Both parts are under Intermediate connection of the plate riveted together.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die bei einfacher Bauweise nur sehr wenig Platz beansprucht, so daß Anfangs- und Endkante der Platte sehr nahe beieinanderliegen. Dies hat zur Folge, daß fast die volle Umfangslänge des Lackierzylinders als nutzbare Lackierlänge zur Verfügung steht. Die nutzbare Abwälzung des Lackierzylinderumfangs ist somit sehr groß, das heißt, es besteht eine optimale Formatnutzung.The invention has for its object a device of the type mentioned at the beginning, which takes up very little space with a simple design, so that the start and end edge of the plate are very close together. As a consequence, that almost the full circumferential length of the painting cylinder available as usable painting length stands. The usable rolling of the coating cylinder circumference is therefore very large, that is, it exists optimal format use.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Die Erfindung sieht somit vor, daß für die Befestigung der Platte auf dem Zylinder lediglich die Anfangs- und Endkante mittels der Anfangseinhängeleiste beziehungsweise der Endeinhängeleiste hintergriffen werden. Anfangs- und Endeinhängeleiste können sich daher mit nur sehr geringem Abstand gegenüberliegen, wobei der Abstand lediglich so groß sein muß, daß einerseits durch ein relatives Aufeinanderzubewegen der beiden Leisten ein Spannen der Platte auf den Umfang des Zylinders möglich ist, das heißt, es muß ein hinreichender Spannweg realisierbar sein, und andererseits der Anfangs- und/oder Endkante ein hinreichend großer Eintrittsspalt zur Verfügung stehen, um den Hintergriff zur jeweiligen Befestigungseinrichtung bei der Montage zur ermöglichen beziehungsweise bei der Demontage lösen zu können.This object is achieved by the features of claim 1 solved. The invention thus provides that for the attachment of the plate only the start and end edge on the cylinder by means of the initial hanging bar or of the end hanging bar become. Start and end mounting rails can be therefore facing each other with only a very short distance, the distance must only be so large that on the one hand by moving relative to each other of the two strips stretch the plate the size of the cylinder is possible, that is, it a sufficient span must be possible, and on the other hand the start and / or end edge sufficiently large entry gap available stand around the rear handle to the respective fastening device to enable during assembly or to be able to solve during disassembly.

Wenn im Zuge dieser Anmeldung von einer Ausgestaltung der Platte geredet wird, so ist dies stets auch immer derart zu verstehen, daß diese Ausgestaltung nicht direkt an der Platte vorgesehen ist, sondern an den Profilendleisten, das heißt, die Profilendleisten werden quasi als Bestandteil der Platte angesehen, wobei sie jedoch separate Bauteile darstellen. Wenn also beispielsweise davon gesprochen wird, daß eine Ausnehmung im Bereich der Anfangskante und/oder der Endkante der Platte angeordnet ist, so bedeutet dieses gleichfalls, daß sich die Ausnehmung auch im Bereich der Anfangskante und/oder Endkante der Profilendleiste/Profilendleisten befinden kann.If in the course of this registration of a configuration the record is being talked about, this is always the case also always to be understood in such a way that this configuration is not intended directly on the plate, but on the profile end strips, that is, the End strips are more or less part of the Plate viewed, however, separate components represent. If so, for example it is said that a recess in the area of Arranged the beginning edge and / or the end edge of the plate is, this also means that the recess is also in the area of the start edge and / or end edge of the profile end strip / profile end strips can be located.

Es ist vorgesehen, daß die Profilendleiste beziehungsweise die Profilendleisten an der Platte durch Klemmbefestigung gehalten ist/sind. Hierzu weist jede Profilendleiste vorzugsweise einen Klemmkanal auf, in den die Platte zur Befestigung eingreift. Es ist jedoch auch möglich, daß die Profilendleiste an der Platte durch Klebung gehalten ist. Auch in diesem Falle kann die Profilendleiste einen Kanal aufweisen, in den das Plattenende beziehungsweise der Plattenanfang unter Zwischenschaltung eines Klebers eingreift.It is envisaged that the profile end strip or the profile end strips on the plate Is / are held. This points each profile end strip preferably a clamping channel in which the plate engages for fastening. However, it is also possible that the profile end bar is held on the plate by gluing. Also in In this case, the profile end bar can be a channel have, in which the plate end or the beginning of the record with the interposition of a Glue engages.

Vorteilhaft ist es, wenn die Endeinhängeleiste in tangentialer Richtung von der Spannwelle auskragt. Hinsichtlich einer gedachten Radialen des Zylinders divergiert die Endeinhängeleiste -im Querschnitt gesehen- zu dieser Radialen, wobei der die Endkante der Platte hintergreifende Bereich der Endeinhängeleiste etwa im Bereich des Schnittpunktes der Radialen mit der Umfangslinie des Zylinders liegt. Vorzugsweise divergiert -mit entgegengesetzter Neigung- hierzu die die Anfangskante aufnehmende Anfangseinhängeleiste (ebenfalls im Querschnitt gesehen), das heißt, die beiden Leisten verlaufen geneigt aufeinander zu und bilden zwischen sich nur einen möglichst schmalen Spalt aus, der etwa auf Höhe einer gedachten am äußeren Umfang des Zylinders entlanglaufenden Linie liegt.It is advantageous if the end hanging rail in protrudes tangentially from the tension shaft. Regarding an imaginary radial of the cylinder the end suspension strips diverged - in cross section seen- to this radial, with the the trailing edge area behind the panel of the end suspension rail around the intersection of the radial lies with the circumference of the cylinder. Preferably diverges - with opposite inclination - for this purpose the start hanging bar that receives the start edge (also seen in cross section), that is, the two ledges are inclined towards each other and only form between themselves the narrowest possible gap, which is about Height of an imaginary on the outer circumference of the cylinder along the line.

Die Endeinhängeleiste ist vorzugsweise in sich elastisch, nämlich als Federelement ausgebildet. Durch die elastische Eigenschaft können Ungenauigkeiten an den Enden der Platte, die beispielsweise durch Fertigungstoleranzen (Parallelitätsungenauigkeiten) bewirkt sind, ausgeglichen werden. Da die Endeinhängeleiste an der bereits erwähnten Spannwelle angeordnet ist, läßt sie sich -durch Drehen der Spannwelle- in Richtung der Anfangseinhängeleiste bewegen, wodurch die Platte auf dem Umfang des Zylinders gespannt wird. Insbesondere ist der Spannwelle ein Federelement, vorzugsweise in Form eines Torsionsstabes, zugeordnet, wodurch die Platte stets unter Zugspannung gesetzt ist, wodurch eventuelle Aufwalzeffekte und so weiter aufgenommen werden. Zusätzlich oder alternativ zu der Ausbildung der Endeinhängeleiste als Federelement kann vorgesehen sein, daß die Endeinhängeleiste exzentrisch gelagert ist, das heißt sie kann im Bereich ihres einen Endes verstellt werden, um mögliche Parallelitätsungenauigkeiten der Platte auszugleichen. Das exzentrische Lager befindet sich -wie bereits erwähnt- in einem Endbereich der Endeinhängeleiste, während der andere Endbereich entsprechend verschwenkbar gelagert ist. Da auch am Plattenanfang Parallelitätsungenauigkeiten und dergleichen auftreten können, ist vorzugsweise vorgesehen, daß die Anfangseinhängeleiste ebenfalls den Parallelitätsungenauigkeiten angepaßt werden kann, indem eine "bewegliche" Anfangseinhängeleisten-Befestigung vorliegt. Dies ist vorzugsweise dadurch realisiert, daß der eine Endbereich der Anfangseinhängeleiste mittels eines Befestigungselements, beispielsweise einer Gewindeschraube, durchgriffen wird, derart, daß eine Verschwenkmöglichkeit der Anfangseinhängeleiste geschaffen ist und daß im anderen Endbereich der Anfangseinhängeleiste eine Verstellmöglichkeit, insbesondere mittels eines Hebelmechanismus' besteht, so daß ein entsprechendes Schrägstellen der Anfangseinhängeleiste möglich wird.The end hanging strip is preferably elastic in itself, namely designed as a spring element. By the elastic property can cause inaccuracies at the ends of the plate, for example, by Manufacturing tolerances (parallelism inaccuracies) are caused to be balanced. Because the end hook arranged on the already mentioned tension shaft it can be turned by turning the Tensioning shaft - in the direction of the initial hanging bar move, creating the plate on the circumference of the cylinder is excited. In particular, the tension shaft a spring element, preferably in the form of a Torsion bar, assigned, which makes the plate is always under tension, which means possible Rolling effects and so on added become. In addition or as an alternative to the training the end suspension bar can act as a spring element be provided that the end hanging bar eccentric is stored, that means it can in the area one end be adjusted to make possible Compensate for parallelism inaccuracies of the plate. The eccentric camp is - as already mentioned - in an end area of the end suspension rail, while the other end area accordingly is pivotally mounted. Since also at the beginning of the record Parallelism inaccuracies and the like can occur is preferably provided that the initial hanging bar also the parallelism inaccuracies can be adjusted by a "moveable" start mounting bracket attachment is present. This is preferably achieved by that the one end area of the start hanging bar by means of a fastening element, for example a threaded screw is such that a pivoting possibility of Initial hanging bar is created and that in the other End area of the start hanging bar one Adjustment option, in particular by means of a lever mechanism exists, so that a corresponding It is possible to incline the initial mounting rail becomes.

Der Hintergriffswinkel der Anfangs- und/oder Endkante ist kleiner als 90°, vorzugsweise etwa 60°, das heißt, es liegt quasi ein Formschluß zur jeweiligen Einhängeleiste vor. Schon eine geringfügige Spannung der Platte schließt auf diese Art und Weise aus, daß sich ein Plattenende lösen kann. Andererseits können die Enden der Platte ohne Kraftaufwand beim Lösen der Umfangsspannung abgehoben werden, das heißt, ein Plattenwechsel ist außerordentlich einfach und ohne Mühe möglich.The grip angle of the start and / or end edge is less than 90 °, preferably about 60 °, that is, there is virtually a positive connection to the respective Hanging bar in front. A slight one The tension of the plate closes in this way and Way out that one end of the plate can come loose. on the other hand can the ends of the plate without effort lifted when releasing the circumferential tension become, that is, a plate change is extraordinary easy and effortless.

Bevorzugt ist vorgesehen, daß die Anfangseinhängeleiste und/oder die Endeinhängeleiste im Bezug auf die Anfangskanten- und/oder die Endkantenausbildung in ihrem jeweiligen Hintergriffsbereich derartige Querschnittskonturen aufweisen, daß ein formangepaßtes, großflächiges Aufeinanderliegen der Teile erzielt ist. Dies bietet optimale Sicherheit und Reproduzierbarkeit.It is preferably provided that the initial hanging bar and / or the end hanging rail in the cover on the start edge and / or the end edge formation in their respective backhand area have such cross-sectional contours that a Form-fitting, large-area superimposition of the Parts is achieved. This offers optimal security and reproducibility.

Die Platte kann -nach einer bevorzugten Ausführungsform- ein Kunststoffträgermaterial aufweisen, insbesondere Polyester oder aus diesem Material bestehen. In einem solchen Falle ist die Platte technisch ähnlich einem Gummituch, kann jedoch beispielsweise als Lackplatte zum Lackieren verwendet werden.According to a preferred embodiment, the plate can have a plastic carrier material, in particular polyester or consist of this material. In such a case, the plate is technical similar to a rubber blanket, but can for example used as a lacquer plate for painting become.

Schließlich ist es vorteilhaft, wenn die paßgenaue Lage der Platte -in Laufrichtung des Zylindersdurch ein spielfreies Einhängen der Anfangskante an der Anfangseinhängeleiste erzielt ist. Dies wird automatisch dann sichergestellt, wenn die Platte bei der Montage paßgenau über die Anfangseinhängeleiste gehängt und dann in dieser Position um den Zylinderumfang gespannt wird.Finally, it is advantageous if the exact fit Position of the plate in the direction of the cylinder a play-free attachment of the start edge the initial hanging bar is achieved. this will automatically ensured when the plate during assembly, it fits snugly over the start hanging bar hung and then in this position around the Cylinder circumference is tensioned.

Die Figur 1 zeigt einen Abschnitt eines Zylinders 1, der als Lackierzylinder 2 ausgebildet ist und in einer nicht dargestellten Lackiermaschine verwendet wird. Der Zylinder 1 wird -parallel zu seiner Rotationsachse- von einem Spannkanal 3 durchsetzt, der in die Mantelfläche 4 des Lackierzylinders 2 mündet. Im Querschnitt gesehen weist der Spannkanal 3 eine teilkreisförmige Wandungskontur 5 auf, deren Kreismittelpunkt 6 auf einer Radialen 7 des Lakkierzylinders 2 liegt. Auf der Druckanfangsseite DA geht die teilkreisförmige Wandungskontur 5 in eine Stufenkontur 8 über, die eine Grundfläche 9 und eine Seitenfläche 10 aufweist, wobei Grund- und Seitenfläche vorzugsweise rechtwinklig aufeinanderstehen. Gegenüber einer gedachten, rechtwinklig zur Radialen 7 verlaufenden Ebene 11 schließt die Grundfläche 9 einen spitzen Winkel ein, verläuft also zur Ebene 11 geneigt. Auf der dem Druckende DE zugeordnete Seite des Spannkanals 3 geht die teilkreisförmige Wandungskontur 5 in eine etwa ebene Wandungskontur 12 über, die unter einem spitzen Winkel zur Radialen 7 derart verläuft, daß sie zu dieser Radialen mit Vergrößerung der Entfernung vom Drehpunkt des Lackierzylinders 2 konvergiert. Die Wandungskontur 12 und auch die Seitenfläche 10 münden in die Mantelfläche 4 jeweils unter Ausbildung eines Radius' ein. Figure 1 shows a portion of a cylinder 1, which is designed as a painting cylinder 2 and in used a painting machine, not shown becomes. The cylinder 1 becomes parallel to its axis of rotation penetrated by a tension channel 3, the opens into the outer surface 4 of the painting cylinder 2. Viewed in cross section, the tensioning channel 3 a part-circular wall contour 5, whose Circle center 6 on a radial 7 of the painting cylinder 2 lies. On the print start page DA the part-circular wall contour 5 goes into one Step contour 8 over a base 9 and has a side surface 10, base and The side surface is preferably at right angles to each other. Opposite an imaginary one, perpendicular to the Radial 7 level 11 closes the Base 9 an acute angle, runs so inclined to level 11. On the end of printing DE assigned side of the clamping channel 3 goes the part-circular Wall contour 5 in an approximately flat Wall contour 12 above that pointed under a Angle to the radial 7 is such that it is too of these radials with increasing distance from Pivot point of painting cylinder 2 converges. The Wall contour 12 and also the side surface 10 open in the lateral surface 4 with training of a radius.

Innerhalb des Spannkanals 3 lagert drehbar eine hohle Spannwelle 13, die -im Bereich ihrer Mantelfläche 14- eine Abflachung 15 aufweist, an der eine Endkantenbefestigungseinrichtung 16 angeordnet ist, die eine Endeinhängeleiste 17 aufweist. Im Querschnitt der Figur 1 gesehen erstreckt sich die Endeinhängeleiste 17 auskragend von der Spannwelle 13 weg, wobei das freie Ende 18 der Endeinhängeleiste 17 sich etwa bis zur gedachten Mantelfläche 4 innerhalb des Spannkanals 3 erstreckt. Die Befestigung der Endeinhängeleiste 17 an der Spannwelle 13 erfolgt mittels Gewindeschrauben 19, von denen mehrere über die Länge der Anordnung verteilt beabstandet zueinander angeordnet sind, wobei jede Gewindeschraube 19 eine Aufnahmebohrung der Endeinhängeleiste 17 durchsetzt und in eine Gewindebohrung der hohlen Spannwelle 13 eingeschraubt ist.A is rotatably supported within the tensioning channel 3 hollow tension shaft 13, -in the area of its lateral surface 14- has a flat 15 on which one End edge fastening device 16 is arranged, which has an end hanging bar 17. In cross section seen in Figure 1, the end hanging strip extends 17 projecting from the tension shaft 13 away, with the free end 18 of the end hanging bar 17 approximately up to the imaginary lateral surface 4 within of the tension channel 3 extends. The attachment the end hanging bar 17 on the tension shaft 13 takes place by means of threaded screws 19, several of which spaced apart over the length of the arrangement are arranged to each other, each threaded screw 19 a receiving bore of the end hanging bar 17 interspersed and in a threaded hole the hollow tension shaft 13 is screwed.

Eine entsprechende Möglichkeit ist bei der Endeinhängeleiste 17 gegeben. Diese wird dadurch geschaffen, daß ein Ende der Endeinhängeleiste 17 exzentrisch gelagert ist, so daß mögliche Parallelitätsungenauigkeiten der Platte 28 ausgeglichen werden können.In the step contour 8 is an initial edge fastening device 22 used, which is an initial hanging bar 23 has. The start hanging bar 23 is in one end region with a Threaded screw 24 connected to the painting cylinder 2. For this purpose, the start hanging bar 23 a stepped bore 25 on the threaded screw 24 is penetrated, the threaded portion the threaded screw 24 in a corresponding Threaded bore 26 of the painting cylinder 2 is screwed in. In the area of their other end the initial hanging bar 23 has an adjustment device, especially a lever-like one Adjustment device so that it is in the circumferential direction of the painting cylinder 2 considered Axis of rotation of the painting cylinder inclined can be to any parallelism inaccuracies one on the outer surface 4 of the painting cylinder Compensate 2 flexible plate 28 to be fastened to be able to. A corresponding possibility is given at the end hanging bar 17. This is created in that one end of the end hook 17 is mounted eccentrically, so that possible parallelism inaccuracies of the plate 28 can be compensated.

Mittels einer von der Endkantenbefestigungseinrichtung 16 und der Anfangskantenbefestigungseinrichtung 22 gebildeten Vorrichtung 27 wird die biegsame Platte 28 auf der Mantelfläche 4 des Lackierzylinders 2 befestigt. Die Platte 28 ist als Lackplatte 29 ausgebildet, so daß mit ihr Lackierarbeiten durchgeführt werden können. Die Platte 28 weist an ihrem Anfang 30 eine Kante 31 und an ihrem Ende 32 eine Kante 33 auf, wobei die Kante 31 eine Anfangskante 34 und die Kante 33 eine Endkante 35 bildet. Anfangskante 34 und Endkante 35 sind durch Abbiegen der jeweiligen Endbereiche der Platte 28 gebildet. Die Abbiegung ist derart erfolgt, daß die Anfangskante 34 beziehungsweise die Endkante 35 jeweils einen spitzen Winkel zu der Mantelfläche 4 angepaßten Kontur der Platte 28 bilden. Durch diese hakenförmigen Konturen werden Hintergriffswinkel von vorzugsweise etwa 60° gebildet. Den Hintergriffswinkeln entsprechende Gegenkonturen sind an der Anfangseinhängeleiste 23 sowie im Bereich des freien Endes 18 der Endeinhängeleiste 17 ausgebildet. Die Anordnung ist derart getroffen, daß die Anfangseinhängeleiste 23 und die Endeinhängeleiste 17 in ihrem jeweiligen Hintergriffsbereich derartige Querschnittskonturen aufweisen, daß ein formangepaßtes, großflächiges Aufliegen der Anfangskante 34 und der Endkante 35 der Platte 28 vorliegt. Die an die Anfangskante 34 und die Endkante 35 angrenzenden Bereiche der Platte 28, die auf der gedachten Mantelflächenkontur des Lackierzylinders 2 liegen beziehungsweise etwa der Mantelflächenkontur folgen, stützen sich ebenfalls flächig an entsprechenden Bereichen der Anfangseinhängeleiste 23 sowie Endeinhängeleiste 17 ab.By means of one of the end edge fastening device 16 and the leading edge fastener 22 formed device 27 becomes the flexible Plate 28 on the outer surface 4 of the painting cylinder 2 attached. The plate 28 is a lacquer plate 29 trained so that painting work with her can be carried out. The plate 28 instructs an edge 31 at its beginning 30 and 32 at its end an edge 33, the edge 31 being a starting edge 34 and the edge 33 forms an end edge 35. Start edge 34 and end edge 35 are by bending of the respective end regions of the plate 28. The turn is made so that the start edge 34 and the end edge 35 each adapted an acute angle to the lateral surface 4 Form the contour of the plate 28. Through this hook-shaped Contours become backhand angles from preferably formed about 60 °. The rear grip angles corresponding counter contours are on the initial hanging bar 23 and in the area of Free end 18 of the end hanging bar 17 is formed. The arrangement is such that the Start hanging bar 23 and the end hanging bar 17 in their respective rear grip area Cross-sectional contours have a shape-matched large contact of the start edge 34 and the end edge 35 of the plate 28 is present. That at the start edge 34 and the end edge 35 adjacent areas of the plate 28, which on the imaginary lateral surface contour of the painting cylinder 2 or approximately the outer surface contour follow, are also supported extensively on corresponding Areas of the initial hanging bar 23 as well as end hanging bar 17 from.

Eine korrekte seitliche Ausrichtung der Platte 28 auf dem Zylinder 1, also beispielsweise die Mittellage, ist durch die Ausrichteinrichtung 42 sichergestellt. Diese weist einen Stift 43 mit Kopf 43' auf, der mit einem Ende in der Anfangseinhängeleiste 23 gehalten wird und dessen anderes, freies Ende in den Spannkanal 3 weist. Der aus der Anfangseinhängeleiste 23 austretende Stift 43 überragt mit der Unterseite seines Kopfes 43' die Oberfläche der Anfangseinhängeleiste 23 etwa um eine Länge, die der Dicke der Platte 28 entspricht. Der Stift 43 durchdringt eine Ausnehmung 44, die in die Anfangskante 34 der Platte 28 eingebracht ist und eine Anschlagkante 45 bildet. Hierdurch ist ein reproduzierbares, paßgenaues seitliches Positionieren der Platte 28 möglich. Die Ausnehmung 44 wird überflüssig, wenn die Anschlagkante 45 von einer Seitenkante der Platte 28 gebildet wird, die in diesem Fall zur seitlichen Ausrichtung der Platte 28 bis zum Kontakt an den Stift 43 herangefahren wird. Selbstverständlich kann der Stift 43 beziehungsweise die Ausrichteinrichtung 42 auch an der Endeinhängeleiste 17 angeordnet sein. Es können auch mehrere Ausrichteinrichtungen 42 vorgesehen sein. Der besseren Übersicht wegen ist lediglich eine Ausrichteinrichtung 42 in Figur 1 dargestellt.Correct lateral alignment of plate 28 on cylinder 1, for example the middle position, is ensured by the alignment device 42. This has a pin 43 with a head 43 ' on the one with an end in the start hanging bar 23 is held and its other, free End in the clamping channel 3 points. The one from the initial hanging bar 23 protruding pin 43 protrudes with the bottom of his head 43 'the surface the initial hanging bar 23 about one Length corresponding to the thickness of the plate 28. The Pin 43 penetrates a recess 44 which in the Start edge 34 of the plate 28 is introduced and forms a stop edge 45. This is a reproducible, precise lateral positioning the plate 28 possible. The recess 44 will superfluous if the stop edge 45 of a Side edge of the plate 28 is formed, which in in this case for the lateral alignment of the plate 28 move up to contact with pin 43 becomes. Of course, the pin 43 or the alignment device 42 also on the End hanging bar 17 may be arranged. It can several alignment devices 42 are also provided his. For the sake of clarity, it is only an alignment device 42 shown in Figure 1.

Es ergibt sich folgende Funktion: Um eine Platte 28 auf den Lackierzylinder 2 zu spannen, wird zunächst im Bereich des Druckanfanges DA die Anfangskante 34 in Hintergriff zur Anfangseinhängeleiste 23 gebracht, dann um die Mantelfläche 4 des Lackierzylinder 2 herumgelegt und anschließend die Endkante 35 in Hintergriff zur Endeinhängeleiste verbracht. Die Spannwelle 13 befindet sich dabei in einer derartigen Drehstellung, daß die Endeinhängeleiste 17 keinen Zug auf die Endkante 35 ausübt. Die Platte 28 wird nun mittels der Ausrichteinrichtung 42 in die gewünschte seitliche Position verbracht. Anschließend wird mittels des Torsionsstabes 21 eine Federspannung auf die Spannwelle 13 ausgeübt, derart, daß sich das freie Ende 18 der Endeinhängeleiste 17 der Anfangseinhängeleiste 23 nähert, wodurch die Endkante 35 mit Federspannung hintergriffen und auf diese Art und Weise die Platte 28 fest auf die Mantelfläche 4 des Lackierzylinders 2 gespannt wird. Für eine Demontage wird der erwähnte Hintergriff gelöst, das heißt, die Spannwelle 13 wird im Gegenuhrzeigersinn (Figur 1) gedreht, so daß die Endkante 35 freigegeben wird und die Platte 28 vom Lackierzylinder 2 entnommen werden kann. The following function results: around a plate 28 To tension on the painting cylinder 2 is first in the area of the print start DA the start edge 34 brought into engagement with the start hanging bar 23, then around the lateral surface 4 of the painting cylinder 2 laid around and then the end edge 35 spent in rear grip on the end hanging bar. The tensioning shaft 13 is in such a way Rotation position that the end hanging bar 17th does not exert any tension on the end edge 35. The plate 28 is now shown in FIG the desired lateral position is spent. Subsequently becomes a by means of the torsion bar 21 Spring tension exerted on the tension shaft 13, such that that the free end 18 of the end hanging bar 17 approaches the initial hanging bar 23, whereby grip the end edge 35 with spring tension and in this way, the plate 28 firmly on the Shell surface 4 of the painting cylinder 2 stretched becomes. For a disassembly, the mentioned rear grip is used solved, that is, the tension shaft 13 is in Counterclockwise (Figure 1) rotated so that the End edge 35 is released and the plate 28 from Paint cylinder 2 can be removed.
