Description

In der heutigen Hülsentechnik, d. h. in der Technologie für den kanallosen Druck - und zwar mit Gummituch und Druckform - ist es üblich zum Aufbringen der hülsenförmigen Druck- oder Übertragungsform auf eine Druckwalze, die Druck- oder Übertragungsform unter Aufweiten mittels Druckluft auf die Druckwalze aufzuschieben. Die Wegnahme der Druckluft bewirkt ein formschlüssiges Anlegen der Druck- oder Übertragungsform nach dem Prinzip einer Schrumpfpassung auf der Druckwalze. Durch erneute Zufuhr von Druckluft kann die Druck- oder Übertragungsform wieder von der Druckwalze genommen werden.In today's sleeve technology, d. H. in technology for canalless printing - and with a blanket and printing form - it is common to apply the sleeve-shaped printing or transfer form on a printing roller, the printing or Form of transmission with expansion by means of compressed air on the pressure roller to postpone. The removal of the compressed air results in a positive engagement the printing or transmission form according to the principle of a shrink fit on the Pressure roller. By re-supplying compressed air, the compressed or Transfer form to be removed from the printing roller again.

Ein Beispiel dieser Hülsentechnik zeigt Dokument EP-A-0 366 395.An example of this sleeve technique is shown in document EP-A-0 366 395.

In der Regel ist eine solche Druckwalze aus einem metallischen Werkstoff gefertigt und weist vorzugsweise als Korrosionsschutz vor gängigen Druckmedien eine Chrombeschichtung auf.Such a pressure roller is usually made of a metallic material and preferably has a corrosion protection against common print media Chrome plating.

Aus der deutschen Patentanmeldung P 43 42 159.8 ist eine derartige Druckwalze bekannt geworden. Dort ist eine hülsenförmige Druckform beschrieben. Die Hülse, deren Innendurchmesser kleiner als der Zylinderdurchmesser des tragenden Teils ist, wird nach dem Vorzentrieren mittels eines kegelförmigen Fasenstücks des Druckwalzenkörpers mechanisch auf den größeren Zylinderdurchmesser aufgeweitet, so daß die Hülse über ein Luftkissen vollständig auf den Walzenkörper aufgeschoben werden kann.Such a pressure roller is known from German patent application P 43 42 159.8 known. A sleeve-shaped printing form is described there. The sleeve, whose inner diameter is smaller than the cylinder diameter of the supporting part is, after precentering by means of a conical chamfer piece of the Pressure roller body mechanically on the larger cylinder diameter widened, so that the sleeve over an air cushion completely on the roller body can be postponed.

Desweiteren ist es heutzutage in der Druckindustrie bekannt, zur Justage von herkömmlichen Gummitüchern und plattenförmigen Druckformen, aber auch zur Verlängerung und zur Verminderung des Druckbildes Kunststoff-Folien als Unterlage zu verwenden. Die Übertragung solcher Kunststoff-Folien auf die Hülsentechnik ist jedoch bis jetzt nicht möglich. Furthermore, it is known today in the printing industry for the adjustment of conventional blankets and plate-like printing forms, but also for Extension and reduction of the print image plastic film as a base to use. The transfer of such plastic films to the sleeve technology is however not possible until now.

In der EP 0 452 184 A1 ist eine Gummituchhülse für einen Gummituchzylinder ohne. Spannkanal gezeigt, die mittels einer klebenden Zwischenschicht auf der Umfangsfläche des Gummituchzylinders fixiert ist. In EP 0 452 184 A1 there is a blanket sleeve for a blanket cylinder. Tension channel shown, which is by means of an adhesive intermediate layer on the Circumferential surface of the blanket cylinder is fixed.

Aufgabe der vorliegenden Erfindung ist es deshalb, eine gattungsbildende Druckwalze derart weiterzubilden, daß beim Aufschieben einer hülsenförmigen Druck- oder Übertragungsform auf die Druckwalze diese genau und ortsfest auf der Druckwalze justiert, bzw. montiert werden kann, ohne daß das der Hülsentechnik zugrunde liegende Prinzip eingeschränkt wird.The object of the present invention is therefore a to further develop the generic printing roller in such a way that Slip on a sleeve-like printing or transfer form the pressure roller adjusts it precisely and stationary on the pressure roller, or can be assembled without the base of the sleeve technology principle is limited.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Bevorzugte Ausgestaltungen der übergeordneten Maßnahmen sind den Unteransprüchen zu entnehmen.This object is achieved by the features of the claim 1 solved. Preferred configurations of the overriding measures can be found in the subclaims.

Ein bevorzugtes Ausführungsbeispiel der Erfindung wird im folgenden unter Bezugnahme der Zeichnung beschrieben.A preferred embodiment of the invention is as follows described with reference to the drawing.

Die einzige Figur zeigt stark schematisiert einen teilweisen Längsschnitt einer Druckwalze, auf deren Walzenkern 1 teilweise eine Druck- oder Übertragungsform 2 aufgeschoben ist.The single figure shows a partial schematic Longitudinal section of a pressure roller, on the roller core 1 partially one Printing or transfer form 2 is postponed.

Der Walzenkern 1 ist üblicherweise als Hohlkörper ausgebildet, der im Vergleich zur hülsenförmigen Druck- oder Übertragungsform 2 eine größere Wandstärke aufweist. Größtenteils ist der Walzenkern 1 mit einem größeren Zylinderdurchmesser ausgeführt als der Innendurchmesser der Druck- oder Übertragungsform 2 beträgt.The roller core 1 is usually designed as a hollow body in comparison to the sleeve-shaped printing or transfer form 2 a larger one Has wall thickness. For the most part, the roll core 1 with one larger cylinder diameter than the inner diameter of the Printing or transmission form 2.

Um das Aufziehen der Druck- oder Übertragungsform 2 zu erleichtern, ist an einer Stirnseite der Druckwalze ein Zylinderstück in Form eines Vorzentrierkonuses 3 mit kleinerem Durchmesser als der Innendurchmesser des Druckzylinders 2 vorgesehen, mittels diesem der Druckzylinder 2 grob auf der Druckwalze positioniert werden kann.In order to facilitate the mounting of printing or transfer form 2, is a cylinder piece in shape on one end of the pressure roller a pre-centering cone 3 with a smaller diameter than that Inside diameter of the printing cylinder 2 is provided, by means of this Printing cylinder 2 can be roughly positioned on the printing roller.

Durch ein weiteres Aufschieben auf einen kegelförmigen Aufschiebekonus 4 der Druckwalze wird der Druckzylinder 2 auf einen Durchmesser entsprechend dem Durchmesser des Oberflächenbereichs 5 des Walzenkerns 1, in dem die Luftauslaßbohrungen 6 münden, aufgeweitet. Beim Passieren der Luftauslaßbohrungen 6 wird der Druckzylinder 2 durch die austretende Luft elastisch gedehnt und kann auf einem Druckluftpolster in seine Endposition auf der Druckwalze gleiten.By pushing it further onto a conical one Sliding cone 4 of the printing roller, the printing cylinder 2 is on a Diameter corresponding to the diameter of the surface area 5 of the roll core 1, in which the air outlet holes 6 open, expanded. When passing the air outlet holes 6, the Printing cylinder 2 stretched elastically by the escaping air and can be in its final position on the on a compressed air cushion Slide the print roller.

Zwischen der Oberfläche des Walzenkerns 1 und der Innenoberfläche des hülsenförmigen Druckzylinders 2 ist eine dünne Zwischenschicht 7 zur Justage und besseren Verankerung des Druckzylinder 2 auf der Druckwalze vorgesehen.Between the surface of the roll core 1 and the inner surface of the sleeve-shaped impression cylinder 2 is a thin intermediate layer 7 for adjustment and better anchoring of the pressure cylinder 2 on the Print roller provided.

Dafür weist die Oberfläche des Walzenkerns 1 einen entsprechend der Dicke der dünnen Zwischenschicht 7 abgesetzten Bereich 9 in Form einer Durchmesserveringerung auf, so daß die Oberflächenbereiche 5 des Walzenkerns 1, in die die Luftauslaßbohrungen 6 münden, gegenüber dem abgesetzten Bereich 9 erhöht liegen.For this purpose, the surface of the roll core 1 has a corresponding Thickness of the thin intermediate layer 7 of the offset region 9 in shape a reduction in diameter so that the surface areas 5 of the roll core 1, into which the air outlet holes 6 open, lie higher than the offset area 9.

Der abgesetzte Bereich 9 des Walzenkerns 1 ist rundum mit der dünnen Zwischenschicht 7 belegt, derart, das der Oberflächenbereich 5 mit den Luftauslaßbohrungen 6 und der abgesetzte Oberflächenbereich 9 des Walzenkerns 1 mit der Zwischenschichtbelegung plan verlaufen. Beide Stirnseiten einer derartigen Druckwalze können gleich ausgeführt sein.The stepped area 9 of the roll core 1 is all around with the thin one Intermediate layer 7 is coated, in such a way that the surface area 5 also the air outlet holes 6 and the stepped surface area 9 of the roll core 1 with the interlayer covering run flat. Both end faces of such a pressure roller can be the same be executed.

Im vorliegenden Beispiel ist die dünne Zwischenschicht 7 eine selbstklebende Kunststoff-Folie, die leicht austauschbar ist. Zum genauen Zuschnitt der Folie auf dem Walzenkern 1 ist zwischen einem abgesetzten Bereich 9 und einem erhöht liegenden Bereich 5 jeweils rundum des Walzenkerns 1 verlaufend ein Einstich 8 zur Führung eines Schneidwerkzeuges vorgesehen.In the present example, the thin intermediate layer 7 is one self-adhesive plastic film that is easy to replace. To the exact cutting of the film on the roll core 1 is between one offset area 9 and an elevated area 5 each A groove 8 runs around the roll core 1 for guidance a cutting tool provided.

Alternativ zur Folie kann die dünne Zwischenschicht 7 auch als Beschichtung der kompletten Oberfläche, vorzugsweise des abgesetzten Oberflächenbereichs 9 des Walzenkerns 1 ausgebildet sein. Die Beschichtung kann aus Kunststoff, Lack, metallischem Basiswerkstoff oder aus keramischen Werkstoffen bestehen. As an alternative to the film, the thin intermediate layer 7 can also be used as Coating of the entire surface, preferably the stepped one Surface area 9 of the roll core 1 may be formed. The Coating can be made of plastic, paint, metallic base material or consist of ceramic materials.

Im Besonderen ist als Zwischenschicht 7 eine GfK-Beschichtung vorgesehen, die thermisch isolierend wirkt. Ein weiterer Vorteil einer solchen Beschichtung wäre die thermische Isolation des Walzenkerns 1, wodurch eine Kühlung der hülsenförmigen Druckform 2 erleichtert wäre.In particular, a GfK coating is used as the intermediate layer 7 provided that acts thermally insulating. Another advantage such a coating would be the thermal insulation of the Roll core 1, whereby cooling of the sleeve-shaped printing form 2nd would be relieved.

Andererseits verhindert eine thermisch isolierende Zwischenschicht 7 einen unerwünschten Abfluß von Wärme von der hülsenförmigen Druckform in den Walzenkern 1. Dies wiederum hat Vorteile beim Befüllen von Tiefdruckformhülsen mit einer thermoplastischen Substanz, sowie allgemein bei durch Wärme unterstützten Thermotransferverfahren.On the other hand, a thermally insulating intermediate layer 7 prevents an undesirable outflow of heat from the sleeve-shaped Printing form in the roll core 1. This in turn has advantages in Filling of gravure form sleeves with a thermoplastic Substance, as well as in general in the case of heat-assisted Thermal transfer process.

Es ist auch denkbar, eine Kunststoff-Folie auf die komplette Oberfläche des Walzenkerns 1, der dann keinen abgesetzten Oberflächenbereich aufweist, zu kleben. Hierbei müssen dann die Luftauslaßbohrungen in der Folie ausgespart werden.It is also conceivable to complete a plastic film Surface of the roll core 1, which is then no stepped Surface area to stick. Here, the Air outlet holes in the film can be left out.

Analog dazu kann natürlich die dünne Zwischenschicht auch selbst als austauschbare Hülse ausgebildet sein.Analogously, the thin intermediate layer can of course also be used as replaceable sleeve be formed.

Auf einer derart ausgebildeten Druckwalze ist es somit möglich, hülsenförmige Druckzylinder in Form von Gummitüchern oder Druckformen wie bei dem herkömmlichen Offset-Druck, bei dem die Gummitücher und Druckformen nicht hülsenförmig vorliegen, einerseits zu justieren und andererseits eine optimale Haftung auf dem Walzenkern zu bieten.On a printing roller designed in this way it is thus possible sleeve-shaped printing cylinders in the form of rubber blankets or Printing forms as in conventional offset printing, in which the Blankets and printing forms are not sleeve-shaped, on the one hand to adjust and on the other hand optimal adhesion on the To offer roll core.
