Description

Die Erfindung betrifft ein radial dehnbares, hülsenförmiges Drucktuch und Verfahren zur Herstellung eines Drucktuches, wobei das Drucktuch zumindest eine innere Trägerschicht, eine als Gewebeschicht ausgebildete Zwischenschicht und eine äußere Deckschicht aufweist.The invention relates to a radially expansible, sleeve-shaped blanket and method for producing a blanket, wherein the blanket has at least one inner carrier layer, an intermediate layer formed as a fabric layer and an outer cover layer.

Drucktücher sind aus dem Stand der Technik hinlänglich bekannt. Dazu wird beispielhaft verwiesen auf folgende Druckschriften: US 3,652,376 , US 3,700,541 , US 4,042,743 , US 4,770,928 , GB 2,016,373 , EP 0 452 184 und US 6,386,100 .Blankets are well known in the art. For example, reference is made to the following publications: US 3,652,376 . US 3,700,541 . US 4,042,743 . US 4,770,928 . GB 2,016,373 . EP 0 452 184 and US 6,386,100 ,

EP 1 268 218 B1 beschreibt eine andere Gattung von Drucktüchern als die vorliegende Erfindung, nämlich ein flächiges Bildübertragungsgummituch mit einer undehnbaren Grundschicht in Form einer flächigen Metallplatte, die mit ihren Enden in einem Spannspalt eines Drucktuchzylinders eingespannt werden kann. Solche Drucktücher weisen aufgrund ihrer Undehnbarkeit deutlich andere Materialeigenschaften auf als radial dehnbare hülsenförmige Drucktücher und sie besitzen auch eine deutlich andere räumlich-geometrische Struktur. Die EP 1 268 218 B1 führt in Spalte 4 aus, dass es nicht praktikabel ist, ein übliches Gewebe-Drucktuch auf eine undehnbare Metell-Grundschchicht zu montieren, weil das daraus resultierende Drucktuch extrem schwer zu handhaben und zu verspannen ist. EP 1 268 218 B1 describes a type of printing blankets other than the present invention, namely a flat image transfer blanket having an inextensible base layer in the form of a flat metal plate which can be clamped by its ends in a clamping gap of a blanket cylinder. Such printing blankets have significantly different material properties due to their inextricability than radially expandable sleeve-shaped blankets and they also have a significantly different spatial-geometric structure. The EP 1 268 218 B1 at column 4 states that it is impractical to mount a standard tissue blanket on an undetachable metal base liner because the resulting blanket is extremely difficult to handle and tense.

Gewebeschichten werden dadurch erzeugt, dass - in der Regel parallel zueinander angeordnete - Kettfäden in Längsrichtung der zu erzeugenden Gewebe-Materialbahn aufgespannt oder sonst geeignet bereitgestellt werden und dann - in der Regel nach gegenseitigem räumlichen Versatz zumindest eines Teils der Kettfäden, in der Regel in einer Richtung senkrecht zu der Gewebe-Materialbahn - Schussfäden zwischen die Kettfäden eingeführt werden, um die Verwebung des Gewebes herzustellen. Damit ist eine solche Gewebeschicht üblicherweise automatisch so ausgerichtet, dass die Kettfäden in Längsrichtung der Materialbahn und die Schussfäden in einer Richtung quer zur Materialbahn angeordnet sind. Kettfäden und Schussfäden weisen dabei unterschiedliche Materialeigenschaften auf. So sind die Kettfäden aufgrund der angenommenen höheren mechanischen Belastung von Geweben in der Regel geeignet verstärkt, um diese höheren mechanischen Belastungen aufnehmen zu können. Gewebe sind also inhomogen bezüglich ihrer Materialeigenschaften, weisen also in Richtung der Kettfäden andere Materialeigenschaften auf als in Richtung der Schussfäden.Fabric layers are produced in that - usually arranged parallel to each other - warp threads in the longitudinal direction of the fabric web to be produced stretched or otherwise provided and then - usually after mutual spatial offset of at least a portion of the warp threads, usually in one Direction perpendicular to the fabric web - wefts are inserted between the warp threads to make the interweaving of the fabric. Thus, such a tissue layer is usually automatic aligned so that the warp threads are arranged in the longitudinal direction of the material web and the weft threads in a direction transverse to the material web. Warp threads and weft threads have different material properties. Thus, the warp threads are due to the assumed higher mechanical load of fabrics usually reinforced suitably to accommodate these higher mechanical loads can. Tissues are thus inhomogeneous with respect to their material properties, ie have different material properties in the direction of the warp threads than in the direction of the weft threads.

Gleiches gilt für Drucktuch-Materialbahnen, die Gewebeschichten enthalten. Normalerweise weist eine Drucktuch-Materialbahn bereits die gewünschte Ausdehnung auf, die für die Ausdehnung eines Drucktuches in axialer Richtung eines Drucktuchzylinders, der mit dem Drucktuch bestückt werde soll, erforderlich ist. Es werden daher bisher Teilstücke von der Drucktuch-Materialbahn abgeschnitten, deren Länge in Längsrichtung der Materialbahn der Umfangslänge des zu bestückenden Drucktuchzylinders entspricht, so dass dann auf dem Drucktuchzylinder automatisch die Kettfäden der Gewebeschicht des Drucktuches in Umfangsrichtung des Drucktuchzylinders angeordnet sind. Dies ist in den Figuren 1, 2 und 8 dargestellt.The same applies to blanket webs containing fabric layers. Normally, a blanket web already has the desired extent which is required for the expansion of a blanket in the axial direction of a blanket cylinder which is to be equipped with the blanket. Therefore, sections of the printing blanket material web are cut off so far whose length in the longitudinal direction of the material web corresponds to the circumferential length of the blanket cylinder to be loaded, so that then automatically the warp threads of the fabric layer of the blanket in the circumferential direction of the blanket cylinder are arranged on the blanket cylinder. This is in the FIGS. 1, 2 and 8th shown.

Es hat sich aber überraschend herausgestellt, dass eine solche Drucktuchanordnung noch gewisse Nachteile bezüglich des Bahntransportes einer Papierbahn in einer Druckmaschine aufweist, ebenso die Registerfähigkeit des Drucktuches nicht optimal ausgeprägt ist.However, it has surprisingly been found that such a blanket arrangement still has certain disadvantages with respect to the web transport of a paper web in a printing machine, as well as the registerability of the blanket is not optimally pronounced.

Aufgabe der vorliegenden Erfindung ist es daher, die o.g. Nachteile zu beheben. Diese Aufgabe wird gelöst durch die Merkmale der unabhängigen Ansprüche 1, 5 und 6.Object of the present invention is therefore, the o.g. To fix disadvantages. This object is solved by the features of independent claims 1, 5 and 6.

Ein erster Gegenstand der Erfindung betrifft ein Drucktuch zur Befestigung auf einem Drucktuchzylinder, zumindest aufweisend einer innere Trägerschicht, eine als Gewebeschicht ausgebildete erste Zwischenschicht und eine äußere Deckschicht, wobei die Gewebeschicht Kettfäden und Schussfäden beinhaltet. Gemäß der Erfindung ist vorgesehen, dass das Drucktuch derart auf dem Drucktuchzylinder befestigbar ist, dass sich die Kettfäden in Axialrichtung des Drucktuchzylinders und die Schussfäden in Umfangsrichtung des Drucktuchzylinders erstrecken. Das Drucktuch ist als hülsenförmiges Drucktuch ausgebildet, das in Form eines Zylinders über den Drucktuchzylinder geschoben werden kann. Dazu ist das Drucktuch radial dehnbar ausgebildet, so dass zum Aufschiebend des Drucktuchs auf den Drucktuchzylinder dieses Drucktuch durch radiale Dehnung aufgeweitet werden kann und dann auf den Drucktuchzylinder durch Nachlassen der radialen Dehnung aufgeschrumpft werden kann.A first subject of the invention relates to a blanket for attachment to a blanket cylinder, at least comprising an inner carrier layer, a first intermediate layer formed as a fabric layer and an outer cover layer, wherein the fabric layer includes warp threads and weft threads. According to the invention it is provided that the blanket can be mounted on the blanket cylinder such that the warp threads extend in the axial direction of the blanket cylinder and the weft threads in the circumferential direction of the blanket cylinder. The blanket is formed as a sleeve-shaped blanket, which can be pushed in the form of a cylinder over the blanket cylinder. For this purpose, the blanket is radially stretchable, so that for pushing the blanket on the blanket cylinder, this blanket can be expanded by radial expansion and then shrunk onto the blanket cylinder by easing the radial expansion.

Durch diese, unübliche aber nach der Erkenntnis der Erfindung vorteilhafte Anordnung, bei der die Kettfäden in Axialrichtung des Drucktuchzylinders und die Schussfäden in Umfangsrichtung angeordnet sind, können optimierte Eigenschaften des Drucktuches bezüglich Bahntransport und Registerfähigkeit erzielt werden. Wie bereits ausgeführt sind die Kettfäden aufgrund der angenommenen höheren mechanischen Belastung von Geweben in der Regel geeignet verstärkt, um diese höheren mechanischen Belastungen aufnehmen zu können. Umgekehrt begünstigt die Anordnung der Schussfäden - welche eine geringere mechanische Stabilität aufweisen - in Umfangsrichtung des Zylinders eine radiale Dehnbarkeit hülsenförmiger Drucktücher. Die Tatsache, dass solche Gewebe inhomogen sind bezüglich ihrer Materialeigenschaften, nämlich in Richtung der Kettfäden andere Materialeigenschaften aufweisen als in Richtung der Schussfäden, wird bei der vorliegenden Erfindung gerade zur Realisierung radial dehnbarer, hülsenförmiger Drucktücher also vorteilhaft genutzt.By this, unusual but advantageous after the realization of the invention arrangement in which the warp threads are arranged in the axial direction of the blanket cylinder and the weft yarns in the circumferential direction, optimized properties of the blanket with respect to web transport and register capability can be achieved. As already stated, the warp threads are usually suitably reinforced due to the assumed higher mechanical load on fabrics in order to be able to absorb these higher mechanical loads. Conversely, the arrangement of the weft threads - which have a lower mechanical stability - in the circumferential direction of the cylinder promotes a radial extensibility of sleeve-shaped blankets. The fact that such fabrics are inhomogeneous with respect to their material properties, namely in the direction of the warp threads have different material properties than in the direction of the weft threads, is thus advantageously used in the present invention for the realization of radially expansible, sleeve-shaped blankets.

Dabei wird insbesondere vorgesehen, dass die Ausdehnung der Gewebeschicht bzw. des ganzen Drucktuches in Richtung der Kettfäden größer ist als in Richtung der Schussfäden. Ein solches Drucktuch kann insbesondere bevorzugt in Richtung der Kettfäden eine Ausdehnung größer als 2,5 m aufweisen. Dies wird gerade auch durch die erhöhte mechanische Stabilität der Kettfäden ermöglicht.In this case, provision is made in particular for the extent of the fabric layer or the entire blanket to be greater in the direction of the warp threads than in the direction of the weft threads. In particular, such a blanket may preferably have an extent greater than 2.5 m in the direction of the warp threads. This is made possible by the increased mechanical stability of the warp threads.

Weiterhin kann vorgesehen sein, dass die Trägerschicht als Metallschicht oder Kunststoffschicht oder Gewebeschicht ausgebildet ist oder auch als eine Kombination dieser vorgenannten Materialschichten. Die Trägerschicht ist insbesondere so ausgebildet, dass sie eine betriebssichere Montage des Drucktuches auf dem Drucktuchzylinder gestattet, kann aber auch zusätzlich eine stützende und stabilisierende, speziell formstabilisierende Wirkung aufweisen, wie sie zB bei Metall-Trägerschichten oder Kunststoff-Trägerschichten aufgrund der Steifheit des Materials gegeben ist.Furthermore, it can be provided that the carrier layer is formed as a metal layer or plastic layer or fabric layer or as a combination this aforementioned material layers. The carrier layer is in particular designed so that it allows a reliable assembly of the blanket on the blanket cylinder, but may also additionally have a supporting and stabilizing, especially shape-stabilizing effect, as given for example in metal carrier layers or plastic carrier layers due to the stiffness of the material is.

Es kann weiter vorgesehen werden, dass zwischen der Trägerschicht und der oben beschriebenen Gewebeschicht eine als kompressible Schicht ausgebildete zweite Zwischenschicht angeordnet ist.It can further be provided that a second intermediate layer formed as a compressible layer is arranged between the carrier layer and the fabric layer described above.

Ein weiterer Gegenstand der Erfindung ist ein Druckwerk für eine Rollendruckmaschine, zumindest aufweisend

  • einen Formzylinder mit einer Druckplatte, die mindestens 96 Druckseiten aufweist
  • einen Drucktuchzylinder mit einem Drucktuch, zumindest aufweisend eine innere Trägerschicht, eine als Gewebeschicht ausgebildete erste Zwischenschicht und eine äußere Deckschicht, wobei die Gewebeschicht Kettfäden und Schussfäden beinhaltet,
wobei das Drucktuch derart auf dem Drucktuchzylinder befestigt ist, dass sich die Kettfäden in Axialrichtung des Drucktuchzylinders und die Schussfäden in Umfangsrichtung des Drucktuchzylinders erstrecken. Das Drucktuch ist als hülsenförmiges Drucktuch ausgebildet, das in Form eines Zylinders über den Drucktuchzylinder geschoben werden kann. Dazu ist das Drucktuch radial dehnbar ausgebildet, so dass zum Aufschiebend des Drucktuchs auf den Drucktuchzylinder dieses Drucktuch durch radiale Dehnung aufgeweitet werden kann und dann auf den Drucktuchzylinder durch Nachlassen der radialen Dehnung aufgeschrumpft werden kann.Another object of the invention is a printing unit for a web-fed printing press, at least comprising
  • a form cylinder with a printing plate, which has at least 96 printed pages
  • a blanket cylinder having a blanket, at least comprising an inner carrier layer, a first intermediate layer formed as a fabric layer and an outer cover layer, wherein the fabric layer includes warp threads and weft threads,
wherein the blanket is mounted on the blanket cylinder such that the warp threads extend in the axial direction of the blanket cylinder and the weft threads extend in the circumferential direction of the blanket cylinder. The blanket is formed as a sleeve-shaped blanket, which can be pushed in the form of a cylinder over the blanket cylinder. For this purpose, the blanket is radially stretchable, so that for pushing the blanket on the blanket cylinder this blanket can be widened by radial expansion and then shrunk onto the blanket cylinder by easing the radial expansion.

Dieses Drucktuch kann im Rahmen des erfindungsgemäßen Druckwerkes auch analog zum oben beschriebenen erfindungsgemäßen Drucktuchs weitergebildet sein, also auch die o.g. Merkmale des Drucktuchs einzeln oder in Kombination aufweisen.This printing blanket can be further developed in the context of the printing unit according to the invention also analogous to the printing blanket according to the invention described above be so also have the above features of the blanket individually or in combination.

Die Figuren 1 und 2 zeigen ein Drucktuch 11 nach dem Stand der Technik, das zur Befestigung auf einem Drucktuchzylinder 8 ausgebildet ist. Dieses Drucktuch 11 weist auf: eine innere Trägerschicht 4, eine als Gewebeschicht 6 ausgebildete erste Zwischenschicht und eine äußere Deckschicht 7, wobei die Gewebeschicht 6 Kettfäden 2 und Schussfäden 3 beinhaltet. Dieses Drucktuch 11 ist nach dem Stand der Technik derart auf einem Drucktuchzylinder 8 (wie er beispielsweise in Fig. 5 gezeigt ist) befestigbar, dass sich die Kettfäden 2 in Umfangsrichtung des Drucktuchzylinders 8 und die Schussfäden 3 in Axialrichtung des Drucktuchzylinders 8 erstrecken.The Figures 1 and 2 show a blanket 11 according to the prior art, which is designed for attachment to a blanket cylinder 8. This printing blanket 11 has an inner carrier layer 4, which is designed as a fabric layer 6 first intermediate layer and an outer cover layer 7, wherein the fabric layer 6 includes warp threads 2 and weft threads 3. This blanket 11 is according to the prior art so on a blanket cylinder 8 (as he, for example, in Fig. 5 shown) attachable, that the warp threads 2 extend in the circumferential direction of the blanket cylinder 8 and the weft threads 3 in the axial direction of the blanket cylinder 8.

Dagegen zeigen die Figuren 3 und 4 ein erfindungsgemäßes Drucktuch 1, welches ebenfalls zur Befestigung auf einem Drucktuchzylinder 8 ausgebildet ist. Figuren 5 und 6 zeigen, wie dieses Drucktuch erfindungsgemäß auf dem Drucktuchzylinder 8 befestigt wird. Dieses weist ebenfalls auf: eine innere Trägerschicht 4, eine als Gewebeschicht 6 ausgebildete erste Zwischenschicht und eine äußere Deckschicht 7, wobei die Gewebeschicht 6 Kettfäden 2 und Schussfäden 3 beinhaltet. Nach den Figuren 3 und 4 ist aber das Drucktuch derart auf dem in Fig. 5 gezeigten Drucktuchzylinder 8 befestigbar ist, dass sich die Kettfäden 2 in Axialrichtung A des Drucktuchzylinders 8 und die Schussfäden 3 in Umfangsrichtung des Drucktuchzylinders 8 erstrecken. Fig. 5 zeigt im Querschnitt aus Gründen der Einfachheit nur die Schussfäden 3, wie auch in der Ausschnittsvergrößerung gemäß Fig. 6 erkennbar. Tatsächlich ist aber der Querschnitt wie in Fig. 4 gezeigt so ausgebildet, dass zwischen die Kettfäden 3 die Schussfäden 2 eingewoben sind. Damit zeigt Fig. 4 am deutlichsten die Details im Querschnitt durch das Drucktuch 1 auf dem Drucktuchzylinder 8, Fig. 4 stellt also eine nochmals vergrößerte Querschnittsdarstellung zu Fig. 5 und 6 dar.In contrast, the show FIGS. 3 and 4 an inventive blanket 1, which is also designed for attachment to a blanket cylinder 8. Figures 5 and 6 show how this blanket according to the invention is mounted on the blanket cylinder 8. This also has: an inner carrier layer 4, a first intermediate layer formed as a fabric layer 6 and an outer cover layer 7, wherein the fabric layer 6 includes warp threads 2 and weft threads 3. After the FIGS. 3 and 4 but is the blanket so on the in Fig. 5 shown blanket cylinder 8 is fastened, that the warp threads 2 extend in the axial direction A of the blanket cylinder 8 and the weft threads 3 in the circumferential direction of the blanket cylinder 8. Fig. 5 shows in cross section for reasons of simplicity, only the weft threads 3, as well as in the enlarged detail according to Fig. 6 recognizable. In fact, however, the cross section is as in Fig. 4 shown formed so that between the warp threads 3, the weft threads 2 are woven. Show this Fig. 4 most clearly the details in cross section through the blanket 1 on the blanket cylinder 8, Fig. 4 thus provides a further enlarged cross-sectional view FIGS. 5 and 6 represents.

Die Ausdehnung der Gewebeschicht 6 ist in Richtung der Schussfäden 3 größer ist als in Richtung der Kettfäden 2. Die Trägerschicht 4 ist entweder als Metallschicht ausgebildet, z.B. als Metallrücken bei sogenannten hülsenförmigen Drucktüchern oder Sleeve-Drucktüchern. Die Trägerschicht 4 kann aber auch als Kunststoffschicht oder ähnliche steife, bevorzugt inkompressible Schicht ausgebildet sein. Alternativ kann die Trägerschicht 4 aber auch als besonders verstärkte, zB. formstabilisierende Gewebeschicht ausgebildet sein. Das Drucktuch 1 ist als hülsenförmiges, zylindrisches Drucktuch ausgebildet.The expansion of the fabric layer 6 is greater in the direction of the weft threads 3 than in the direction of the warp threads 2. The carrier layer 4 is either formed as a metal layer, for example as a metal backing in so-called sleeve-shaped blankets or sleeve blankets. However, the carrier layer 4 can also be formed as a plastic layer or similar rigid, preferably incompressible layer. Alternatively, the carrier layer 4 but also as a particularly reinforced, eg. be formed form-stabilizing fabric layer. The blanket 1 is formed as a sleeve-shaped, cylindrical blanket.

Zwischen der Trägerschicht 4 und der Gewebeschicht 6 kann bevorzugt eine als kompressible Schicht 7 ausgebildete zweite Zwischenschicht angeordnet sein. Es können auch noch mehr als die gezeigten Schichten vorgesehen werden, insbesondere noch mehrere kompressible Schichten und Gewebeschichten zwischen Trägerschicht 4 und Deckschicht 7. So kann sich zB. die Abfolge der Zwischenschichten 5 und 6 noch einmal oder mehrfach wiederholen.Between the carrier layer 4 and the fabric layer 6 may preferably be arranged as a compressible layer 7 formed second intermediate layer. It is also possible to provide even more than the layers shown, in particular even more compressible layers and fabric layers between carrier layer 4 and cover layer 7. Thus, for example. Repeat the sequence of intermediate layers 5 and 6 once more or several times.

Ein erfindungsgemäßes Druckwerk für eine Rollendruckmaschine weist einen Formzylinder 16 mit einer Druckplatte 9 auf, die mindestens 96 Druckseiten 10 trägt. Dies ist ausschnitthaft in Fig. 7 dargestellt. Die Druckplatte 10 ist dabei noch in einem Zustand gezeigt in dem sie noch nicht fest auf den Formzylinder 16 aufgespannt ist. Es kann dabei bevorzugt eine einzige Druckplatte vorgesehen sein, die die kompletten mindestens 96 Druckseiten trägt. Alternativ könnten auch mehrere Druckplatten 10 auf dem Formzylinder 16 vorgesehen sein, die insgesamt 96 Seiten tragen. Eine einzige Druckplatte ist aber aus Gründen minimierten Aufwandes bevorzugt.An inventive printing unit for a web-fed printing press has a forme cylinder 16 with a printing plate 9, which carries at least 96 printed pages 10. This is partial in Fig. 7 shown. The pressure plate 10 is still shown in a state in which it is not firmly clamped on the forme cylinder 16. It may be preferred to provide a single pressure plate which carries the complete at least 96 printed pages. Alternatively, a plurality of printing plates 10 could be provided on the forme cylinder 16, which carry a total of 96 pages. A single pressure plate is preferred for reasons of minimized effort.
