Description

Die Erfindung betrifft einen Sleeve, insbesondere eine Gummituchhülse, für eine Druckmaschine.The invention relates to a sleeve, in particular a blanket sleeve, for a printing press.

Sleeves begünstigen ein ruhiges und stossfreies Abrollen von Druckmaschinenzylindern aufeinander infolge der fehlenden Unterbrechung von sonst üblicherweise vorhandenen Spannkanälen am Umfang der Zylinder.Sleeves favor a quiet and shock-free unwinding of printing press cylinders due to the lack of interruption of otherwise commonly existing clamping channels on the circumference of the cylinder.

Die DE 199 50 643 A1 offenbart einen Sleeve für eine Offset-Rollenrotationsdruckmaschine, welcher einen insgesamt vierschichtigen Aufbau aufweist. Der Sleeve gemäß DE 199 50 643 A1 verfügt über eine als Trägerschicht ausgebildete Innenschicht, nämlich eine Metallhülse, sowie eine als Deckschicht ausgebildete, der Druckübertragung dienende Außenschicht, wobei zwischen der Trägerschicht und der Deckschicht zwei weitere Schichten vorhanden sind. An die innere Trägerschicht schließt sich eine kompressible Schicht an, an die äußere Deckschicht schließt sich eine Schicht aus einem nicht dehnbaren Material an. Die sich an die Trägerschicht anschließende kompressible Schicht und die sich an die Deckschicht anschließende Schicht aus nicht dehnbarem Material sind miteinander verbunden.The DE 199 50 643 A1 discloses a sleeve for an offset web-fed rotary printing press having an overall four-layered construction. The sleeve according to DE 199 50 643 A1 has an inner layer formed as a carrier layer, namely a metal sleeve, as well as an outer layer designed as a cover layer and serving for pressure transmission, wherein two further layers are present between the carrier layer and the cover layer. The inner support layer is followed by a compressible layer, to the outer cover layer is followed by a layer of a non-stretchable material. The compressible layer adjoining the carrier layer and the layer of non-stretchable material adjoining the cover layer are connected to one another.

Ein solcher vierschichtig ausgebildeter Sleeve gemäß DE 199 50 643 A1 erfordert einen hohen Fertigungsaufwand und ist damit teuer.Such a four-layer trained sleeve according to DE 199 50 643 A1 requires a high production cost and is therefore expensive.

Die EP 0 594 986 A offenbart eine Offset-Gummituchhülse für einen Kanallosen Gummituchzylinder.The EP 0 594 986 A discloses an offset blanket sleeve for a channelless blanket cylinder.

Es liegt der hier vorliegenden Erfindung das Problem zugrunde, einen neuartigen Sleeve mit Trägerhülse, insbesondere eine neuartige Gummituchhülse, für eine Druckmaschine zu schaffen.It is the object of the present invention to provide a novel sleeve with a carrier sleeve, in particular a novel blanket sleeve, for a printing press.

Dieses Problem wird durch einen Sleeve und eine Trägerhülse, insbesondere eine Gummituchhülse, für eine Druckmaschine gemäß Patentanspruch 1 bzw. 7 gelöst.This problem is solved by a sleeve and a carrier sleeve, in particular a blanket sleeve, for a printing machine according to claim 1 or 7.

Nach einem ersten Aspekt der Erfindung wird ein Sleeve, insbesondere eine Gummituchhülse und eine Trägerhülse gemäß Anspruch 1, für eine Druckmaschine mit einem zweischichtigen Aufbau umfassend eine als Trägerschicht ausgebildete Innenschicht und eine als Deckschicht ausgebildete, der Druckübertragung dienende Außenschicht vorgeschlagen, wobei die Außenschicht bzw. die Deckschicht unmittelbar auf die Innenschicht bzw. die Trägerschicht aufgebracht ist.According to a first aspect of the invention, a sleeve, in particular a rubber blanket sleeve and a carrier sleeve according to claim 1, proposed for a printing machine with a two-layer structure comprising an inner layer formed as a carrier layer and an outer layer serving as a cover layer, the pressure transmission serving, wherein the outer layer or the cover layer is applied directly to the inner layer or the carrier layer.

Nach einem zweiten Aspekt der Erfindung wird ein Sleeve, insbesondere eine Gummituchhülse und eine Trägerhülse gemäß Anspruch 7, für eine Druckmaschine mit einem dreischichtigen Aufbau umfassend eine als Trägerschicht ausgebildete Innenschicht, eine als Deckschicht ausgebildete, der Druckübertragung dienende Außenschicht und eine zwischen der Trägerschicht und der Deckschicht angeordnete Registerschicht vorgeschlagen, wobei die Außenschicht bzw. die Deckschicht und die Innenschicht bzw. die Trägerschicht auf unterschiedlichen Seiten der Registerschicht unmittelbar auf die Registerschicht aufgebracht sind.According to a second aspect of the invention is a sleeve, in particular a blanket sleeve and a carrier sleeve according to claim 7, for a printing press with a three-layer structure comprising an inner layer formed as a carrier layer, an outer layer serving as a cover layer, the pressure transmission serving outer layer and between the carrier layer and the Cover layer arranged arranged register layer, wherein the outer layer or the cover layer and the inner layer or the carrier layer are applied on different sides of the register layer directly on the register layer.

Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung.Preferred embodiments of the invention will become apparent from the dependent claims and the description below.

Ausführungsbeispiele der Erfindung werden, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert. Dabei zeigt:

Fig. 1:

Embodiments of the invention will be described, without being limited thereto, with reference to the drawings. Showing:
Fig. 1:
a schematic cross section through a sleeve according to the invention for a printing press according to a first embodiment of the present invention; and
Fig. 2:
a schematic cross section through a sleeve according to the invention for a printing press according to a second embodiment of the present invention.

Nachfolgend wird die hier vorliegende Erfindung unter Bezugnahme auf Fig. 1 und 2 in größerem Detail beschrieben.Hereinafter, the present invention will be described with reference to FIG Fig. 1 and 2 described in more detail.

Fig. 1 zeigt die besonders bevorzugte Ausführungsform eines Sleeve 10 für eine Offsetdruck-Druckmaschine im Sinne der hier vorliegenden Erfindung. Der Sleeve 10 gemäß Fig. 1 verfügt über einen zweilagigen bzw. zweischichtigen Aufbau. Der Sleeve 10 umfasst eine als Trägerschicht 11 ausgebildete Innenschicht und eine als Deckschicht 12 ausgebildete, der Druckübertragung dienende Außenschicht. Die Außenschicht bzw. Deckschicht 12 ist unmittelbar auf die Innenschicht bzw. die Trägerschicht 11 aufgebracht. Fig. 1 shows the particularly preferred embodiment of a sleeve 10 for an offset printing press according to the present invention. The sleeve 10 according to Fig. 1 has a two-layer or two-layer structure. The sleeve 10 comprises an inner layer designed as a carrier layer 11 and an outer layer designed as a cover layer 12 and used for pressure transmission. The outer layer or cover layer 12 is applied directly to the inner layer or the carrier layer 11.

Es liegt demnach im Sinne der hier vorliegenden Erfindung, die Anzahl der Schichten des Sleeve zu verringern. Nach dem Ausführungsbeispiel der Fig. 1 umfasst der Sleeve 10 lediglich zwei Schichten, nämlich die Trägerschicht 11 sowie die Deckschicht 12. Hierdurch vereinfacht sich einerseits der Aufbau des Sleeve 10 und andererseits ist derselben mit geringeren Kosten herstellbar.It is therefore within the meaning of the present invention to reduce the number of layers of the sleeve. According to the embodiment of Fig. 1 the sleeve 10 comprises only two layers, namely the carrier layer 11 and the cover layer 12. This simplifies on the one hand the construction of the sleeve 10 and on the other hand can be manufactured at a lower cost.

Nach einer bevorzugten Weiterbildung des Ausführungsbeispiels der Fig. 1 ist die Trägerschicht 11 inkompressibel ausgebildet. Die inkompressible Trägerschicht 11 kann zum Beispiel metallisch ausgebildet sein. Nach einer Alternative hierzu ist die Trägerschicht kompressibel ausgebildet und vorzugsweise aus einem faserverstärkten Verbundwerkstoff gebildet.According to a preferred embodiment of the embodiment of Fig. 1 the carrier layer 11 is formed incompressible. The incompressible carrier layer 11 may be formed, for example, metallic. According to an alternative to this, the carrier layer is formed compressible and preferably formed from a fiber-reinforced composite material.

Unabhängig davon, ob die Trägerschicht 11 kompressibel oder inkompressibel ausgebildet ist, ist die Trägerschicht 11 ebenso wie die Deckschicht 12 zu einer Hülse bzw. einem Hohlzylinder verschweißt, sodass der Sleeve 10 auf einen Zylinder einer Druckmaschine aufgeschoben werden kann.Regardless of whether the carrier layer 11 is formed compressible or incompressible, the carrier layer 11 as well as the cover layer 12 is welded to a sleeve or a hollow cylinder, so that the sleeve 10 can be pushed onto a cylinder of a printing press.

Die als Trägerschicht 11 ausgebildete Innenschicht verfügt vorzugsweise über eine Dicke von 0,1 mm bis maximal 100 mm, sodass die Trägerschicht 11 zur Änderung der Drucklänge eingesetzt werden kann.The inner layer formed as a carrier layer 11 preferably has a thickness of 0.1 mm to a maximum of 100 mm, so that the carrier layer 11 can be used to change the printing length.

Die unmittelbar auf die Trägerschicht 11 aufgebrachte Deckschicht 12 dient, wie bereits erwähnt, der Druckübertragung und ist entweder kompressibel oder inkompressibel ausgebildet. Die Deckschicht 12 verfügt vorzugsweise über eine Dicke zwischen 0,1 mm und 10 mm.The cover layer 12 applied directly to the carrier layer 11 serves, as already mentioned, for pressure transmission and is designed to be either compressible or incompressible. The cover layer 12 preferably has a thickness between 0.1 mm and 10 mm.

Besonders bevorzugt ist eine Ausführungsform des Sleeve 10, bei welcher die Deckschicht 12 mit einem Lack oder einem anderen Material versiegelt ist.Particularly preferred is an embodiment of the sleeve 10, in which the cover layer 12 is sealed with a lacquer or other material.

Fig. 2 zeigt ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Sleeve 13, welcher über einen dreilagigen bzw. dreischichtigen Aufbau verfügt. Der Sleeve 13 gemäß Fig. 2 verfügt über eine als Trägerschicht 14 ausgebildete Innenschicht, eine als Deckschicht 15 ausgebildete Außenschicht und eine zwischen der Trägerschicht 14 und der Deckschicht 15 angeordnete Registerschicht 16. Die Innenschicht 14 ist unmittelbar mit einer Innenseite der Registerschicht 16 verbunden. Die Deckschicht 15 ist unmittelbar mit einer Außenseite der Registerschicht 16 verbunden. Auch im Ausführungsbeispiel der Fig. 2 ist die Anzahl der Lagen bzw. Schichten des Sleeve gegenüber dem Stand der Technik reduziert. Auch mit dem Sleeve 13 der Fig. 2 können demnach die Herstellkosten minimiert werden. Fig. 2 shows a further embodiment of a sleeve 13 according to the invention, which has a three-layer or three-layer structure. The sleeve 13 according to Fig. 2 has an inner layer formed as a carrier layer 14, an outer layer formed as a cover layer 15 and a register layer 16 arranged between the carrier layer 14 and the cover layer 15. The inner layer 14 is directly connected to an inner side of the register layer 16. The cover layer 15 is directly connected to an outer side of the register layer 16. Also in the embodiment of Fig. 2 the number of layers of the sleeve is reduced compared to the prior art. Also with the sleeve 13 of the Fig. 2 Accordingly, the manufacturing costs can be minimized.

Beim Sleeve 13 der Fig. 2 ist die Trägerschicht 14 sowie die Deckschicht 15 vorzugsweise kompressibel ausgebildet. Die Registerschicht 16 ist vorzugsweise aus einem inkompressiblen Hartgummi oder einem faserverstärktem Verbundwerkstoff oder einem metallischen Werkstoff gebildet.When Sleeve 13 the Fig. 2 the carrier layer 14 and the cover layer 15 is preferably formed compressible. The register layer 16 is preferably formed of an incompressible hard rubber or a fiber reinforced composite material or a metallic material.

Es ist auch möglich, dass die Trägerschicht 14 inkompressibel und die Deckschicht 15 kompressibel oder die Trägerschicht 14 kompressibel und die Deckschicht 15 inkompressibel ausgebildet ist, bei vorzugsweise jeweils inkompressibel ausgebildeter Registerschicht 16.It is also possible for the carrier layer 14 to be incompressible and the cover layer 15 to be compressible or the carrier layer 14 to be compressible and the cover layer 15 to be incompressible, with the register layer 16 preferably formed incompressibly in each case.

Die erfindungsgemäßen Sleeves 10 und 13 finden vor allem in Offsetdruck-Druckmaschinen Verwendung. Derartige Sleeve-Offsetdruckmaschinen verfügen in der Regel nur über kleine oder gar keine Spannkanäle an den sogenannten Druckformzylindern bzw. Plattenzylindern. Somit ist eine Schwingungsanregung der Druckzylinder minimal, sodass die erfindungsgemäßen Sleeves problemlos verwendet werden können.The sleeves 10 and 13 according to the invention are mainly used in offset printing presses. Such sleeve offset printing machines usually have only small or no clamping channels on the so-called printing cylinders or plate cylinders. Thus, a vibration excitation of the printing cylinder is minimal, so that the inventive sleeves can be used easily.

Die erfindungsgemäßen Sleeves 10 und 13 sind insgesamt flexibel ausgebildet und sind strumpfartig auf eine feste, nicht-dargestellte Trägerhülse aufgezogen , um dann zusammen mit der Trägehülse auf einem Zylinder einer Druckmaschine positioniert zu werden:The sleeves 10 and 13 according to the invention are flexible overall and are stocking mounted on a solid, not shown support sleeve to then be positioned together with the carrier sleeve on a cylinder of a printing press:
