Abstract

The sleeve (1) is formed from a thin rectangular plate bent into a cylindrical shape and joined along the adjacent edges. It can be of aluminium, and for use in offset printing it can be chemically roughened including the joint seam (2), anodised and provided with a sealing photo-sensitive coating. Alternatively, it can be provided with a water-guiding coating. For rotogravure printing it can be provided with an engraved copper coating. For use with a transfer block, the surface can be provided with a continuous laminar rubber coating. It can also be used as a direct support for a flexible block used in flexographic printing.

Description

Die Erfindung betrifft eine Trägerhülse für Druck- und Übertragungsformen aus einem metallischen Werkstoff, deren Ausgangsform ein rechteckiges, dünnwandiges Plattenstück ist, das durch Biegen in die gewünschte Hohlzylinderform gebracht ist und die aufeinander zuweisenden Kanten des Plattenstücks fest miteinander verbunden sind.The invention relates to a carrier sleeve for printing and transfer forms made of a metallic material, the starting form of which is a rectangular, thin-walled plate piece which is bent into the desired hollow cylindrical shape and the mutually facing edges of the plate piece are firmly connected to one another.

Aus dem Flexodruck ist es heutzutage hinreichend bekannt, hülsenförmige Druck- und Übertragungsformen auf galvanisch hergestellten Nickelhülsen aufzubringen. Die auf diese Weise hergestellten Druck- und Übertragungsformen sind in bekannter Weise mittels Preßluft über einen Druckzylinderkern aufschiebbar und darauf durch Abstellen der Luftversorgung fixierbar. Zu diesem Zwecke wurden auch schon Trägerhülsen aus glasfaserverstärktem Kunststoff (GfK) oder gar aus kohlefaserverstärktem Kunststoff (CfK) verwendet. Die Verwendung der Werkstoffe Nickel- GfK oder gar CfK für eine Trägerhülse ist jedoch vergleichsweise sehr teuer.It is well known today from flexographic printing to apply sleeve-shaped printing and transfer forms to electroplated nickel sleeves. The printing and transmission forms produced in this way can be pushed on in a known manner by means of compressed air over a pressure cylinder core and can be fixed thereon by switching off the air supply. Carrier sleeves made of glass fiber reinforced plastic (GRP) or even carbon fiber reinforced plastic (CFRP) have also been used for this purpose. However, the use of nickel GfK or even CfK for a carrier sleeve is comparatively very expensive.

Mit der deutschen Patentanmeldung P 41 40 768 ist eine hülsenförmige Offsetdruckform bekannt geworden, die aus einer rechteckig zugeschnittenen Metallplatte gefertigt wird, indem die aufeinander zuweisenden Kanten der Platte mittels einer Schweißnaht verbunden werden. Die so hergestellte Trägerhülse ist bis auf die Schweißnaht rundum beschichtet und belichtet.With the German patent application P 41 40 768 a sleeve-shaped offset printing form has become known, which is manufactured from a rectangularly cut metal plate by connecting the mutually facing edges of the plate by means of a weld seam. The carrier sleeve produced in this way is coated and exposed all around except for the weld seam.

Mit der DE 42 17 793 C1 ist ein hülsenförmiges Offset-Gummituch offenbart, das ebenfalls aus einer zugeschnittenen Trägerplatte, auf die im planen Zustand eine Gummischicht aufgetragen wird, gefertigt ist, indem Anfang und Ende der Trägerplatte mitsamt der Gummischicht miteinander verschweißt sind.DE 42 17 793 C1 discloses a sleeve-shaped offset rubber blanket which is also made from a cut carrier plate, to which a rubber layer is applied in the flat state, by welding the beginning and end of the carrier plate together with the rubber layer.

Mittels dieser hülsenförmigen Druck- und Übertragungsformen kann zwar kanalfrei, aber nicht endlos gedruckt werden, d. h. es können damit nur endliche Druckprodukte hergestellt werden. Der Einsatz einer endlosen Offset-Druckform ist bis jetzt noch nicht bekannt geworden.By means of these sleeve-shaped printing and transmission forms, channel-free printing is possible, but not endlessly. H. it can only be used to produce finite printed products. The use of an endless offset printing form has not yet become known.

Hiervon ausgehend ist es die Aufgabe der vorliegenden Erfindung vergleichsweise kostengünstige Trägerhülsen sowohl für Druck-, als auch für Übertragungsformen bereitzustellen, durch diese ein Endlos-Druck möglich ist.Proceeding from this, it is the object of the present invention to provide comparatively inexpensive carrier sleeves for both printing and transfer forms, by means of which continuous printing is possible.

Diese Aufgabe wird durch eine Trägerhülse nach Anspruch 1 und die kennzeichnenden Verfahrensschritte des Anspruchs 8 gelöst.This object is achieved by a carrier sleeve according to claim 1 and the characterizing method steps of claim 8.

Durch eine Tragerhülse für Druck- und Übertragungsformen aus einem metallischen Werkstoff, deren Ausgangsform ein rechteckiges, dünnwandiges Plattenstück ist, das durch Biegen in die gewünschte Hohlzylinderform gebracht ist und die aufeinander zuweisenden Kanten des Plattenstücks fest miteinander verbunden sind, bei der die Hülsenoberfläche zur Ausbildung einer homogenen Mantelfläche bearbeitet ist, so daß Endlos-Druck durchführbar ist, wurde zu den Nickel-, GfK- und CfK-Hülsen sowohl unter ökologischer, als auch ökonomischer Sicht eine vorteilhafte Alternative gefunden, die zudem universell für verschiedene Druckverfahren einsetzbar ist.By a support sleeve for printing and transfer forms made of a metallic material, the starting form of which is a rectangular, thin-walled plate piece which is bent into the desired hollow cylindrical shape and the mutually facing edges of the plate piece are firmly connected to one another, in which the sleeve surface forms a homogeneous surface is processed, so that continuous printing can be carried out, an advantageous alternative to the nickel, GRP and CFRP sleeves was found from both an ecological and economic point of view, which is also universally applicable for various printing processes.

Die Herstellungskosten einer geschweißten, erfindungsgemäß bearbeiteten Präzisionshülse liegen um ein Vielfaches unter den Herstellungskosten von galvanischen Nickelhülsen oder gar gewickelten GfK- oder CfK- Trägerhülsen, zumal es immer schwieriger wird, Nickelhülsen galvanisch herzustellen, da dieses Herstellungsverfahren große Umweltbelastungen in sich birgt.The manufacturing costs of a welded precision sleeve machined according to the invention are many times lower than the manufacturing costs of galvanic nickel sleeves or even wound GfK or CfK carrier sleeves, especially since it is becoming increasingly difficult to produce nickel sleeves galvanically, since this manufacturing process entails great environmental pollution.

Des weiteren können in besonders vorteilhafter Weise die erfindungsgemäßen Trägerhülsen in Abhängigkeit des jeweiligen Anwendungsfalles aus Aluminium, Stahl, Edelstahl, Kupfer oder Messing hergesetellt sein.Furthermore, in a particularly advantageous manner, the carrier sleeves according to the invention can be made of aluminum, steel, stainless steel, copper or brass, depending on the particular application.

Fig. 1 zeigt stark schematisiert ein Ausführungsbeispiel einer Trägerhülse 1 aus einem metallischen Werkstoff, der Aluminium, Stahl, Edelstahl oder Messing sein kann. Die Ausgangsform ist ein rechteckiges, dünnwandiges Plattenstück, das durch Biegen in die gewünschte Hohlzylinderform gebracht worden ist. Die aufeinander zuweisenden Kanten des Plattenstücks sind vorzugsweise mittels einer Schweißnaht 2 fest miteinander verbunden.Fig. 1 shows a highly schematic embodiment of a carrier sleeve 1 made of a metallic material, which can be aluminum, steel, stainless steel or brass. The initial shape is a rectangular, thin-walled plate piece that has been bent into the desired hollow cylindrical shape. The mutually facing edges of the plate piece are preferably firmly connected to one another by means of a weld seam 2.

Fig. 2 zeigt die Möglichkeit, die Trägerhülse 1 quasi kontinuierlich herzustellen, wie heute bei der Rohrverschweißung vorgegangen wird. Der Schweißvorgang selbst wird mittels eines Laserstrahls vorgenommen. Die Präzisionsbleche aus Aluminium, Stahl, Edelstahl, Kupfer oder Messing weisen vorzugsweise eine Wandstärke s von 0,1 bis 0,6 mm auf. Die Trägerhülsen können auch mit der aus der DE 43 11 078 bekannten Schweißvorrichtung gefertigt werden.Fig. 2 shows the possibility of producing the carrier sleeve 1 quasi continuously, as is done today for pipe welding. The welding process itself is carried out using a laser beam. The precision sheets made of aluminum, steel, stainless steel, copper or brass preferably have a wall thickness s of 0.1 to 0.6 mm. The carrier sleeves can also be manufactured with the welding device known from DE 43 11 078.

Die außenliegende Oberfläche der geweißten Trägerhülse 1 wird bearbeitet, so daß sich eine homogene, kontinuierliche Mantelfläche einstellt. Bei der Oberflächenbearbeitung kann auf bekannte Fertigungsverfahren wie Drehen, Schleifen oder Ähnliches, womit eine Metalloberfläche glatt wird, zurückgegriffen werden. Die ursprüngliche Wandstärke des dünnwandigen Plattenstücks muß dabei so gewählt werden, daß der Materialabtrag von der außen liegenden Oberfläche der geschweißten Trägerhülse berücksichtigt ist.The outer surface of the whitened carrier sleeve 1 is processed so that a homogeneous, continuous outer surface is obtained. Known manufacturing processes such as turning, grinding or the like, which make a metal surface smooth, can be used for surface processing. The original wall thickness of the thin-walled plate piece must be chosen so that the material removal from the outer surface of the welded carrier sleeve is taken into account.

Eine besonders vorteilhafte Ausführungsform der Schweißnaht ist, wie in Fig. 3 gezeigt, an der außen liegenden Oberfläche der Hülse 1 eine Nahtüberhöhung 3 vorzusehen und in einem folgenden Verfahrensschritt diese so zu bearbeiten, daß eine kontinuierliche, endlose Mantelfläche auf der Trägerhülsenoberfläche entsteht, ohne daß ein Materialabtrag vom Präzisionsblech notwendig ist, oder dieser Materialabtrag zumindest geringer ausfällt.A particularly advantageous embodiment of the weld seam, as shown in FIG. 3, is to provide a seam elevation 3 on the outer surface of the sleeve 1 and to process it in a subsequent process step in such a way that a continuous, endless jacket surface is formed on the carrier sleeve surface without material removal from the precision sheet is necessary, or this material removal is at least less.

Die Nahtüberhöhung 3 wird durch Schweißzusatzwerkstoffe wie z. B. Draht oder Pulver, oder durch gezielte Schutzgasführungen, oder durch eine, dem eigentlichen Schweißprozess nachfolgenden Auftragsschweißung erreicht.The seam increase 3 is by welding filler materials such. B. wire or powder, or by targeted protective gas guides, or achieved by build-up welding following the actual welding process.

Zur Verwendung für den Offsetdruck als Trägerhülse 1 für eine Druckform wird anschließend die gesamte Hülsenoberfläche einschließlich der Verbindungsnaht, im vorliegenden Fall eine Schweißnaht 2, wie bereits durch die Verfahrensschritte bei der Druckplattenherstellung bekannt, chemisch aufgerauht, anodisiert und mit einer abschließenden photoempfindlichen Schicht versehen. Von den drucktechnischen Eigenschaften aus gesehen, ist diese Druckformhülse identisch mit den üblichen Druckplatten, außer daß mit dieser Druckformhülse Endlos-Druck möglich ist. Vorzugsweise werden hierfür Aluminiumbleche verwendet.For use in offset printing as a carrier sleeve 1 for a printing form, the entire sleeve surface including the connecting seam, in the present case a weld seam 2, is chemically roughened, anodized and provided with a final photosensitive layer, as is already known from the process steps in the production of printing plates. Seen from the printing properties, this printing form sleeve is identical to the usual printing plates, except that continuous printing is possible with this printing form sleeve. Aluminum sheets are preferably used for this.

Es ist jedoch auch möglich auf eine Aluminiumhülse oder einer anderen metallischen Hülse eine wasserführende Schicht aufzubringen, wenn der Hülsenwerkstoff selbst nicht wasserführend ist, aber wasserführend gemacht werden soll. Als wasserführende Schichten können beispielsweise keramische Werkstoffe mittels thermischer Spritzverfahren aufgebracht werden.However, it is also possible to apply a water-bearing layer to an aluminum sleeve or another metallic sleeve if the sleeve material itself is not water-bearing, but should be made water-bearing. For example, ceramic materials can be applied as water-bearing layers by means of thermal spray processes.

Für den Hochdruck, insbesondere für den Flexodruck kann diese geschweißte Präzisionshülse 1, die zudem wie oben beschrieben oberflächenbearbeitet ist, direkt als Träger einer flexiblen Druckform, Gummistereo oder gravierten Gummidruckform eingesetzt werden und ersetzt so die bekannten Nickel-, GfK- und CfK-Hülsen.For high pressure, in particular for flexographic printing, this welded precision sleeve 1, which is also surface-treated as described above, can be used directly as a carrier for a flexible printing form, rubber stereo or engraved rubber printing form and thus replaces the known nickel, GfK and CfK sleeves.

Für die Verwendung im Tiefdruck wird auf eine geschweißte Trägerhülse 1, die wie oben beschrieben oberflächenbearbeitet ist, rundum eine metallische Schicht, vorzugsweise eine Kupferlegierung galvanisiert oder gespritzt, die wiederum in einem nachfolgenden Arbeitsschritt graviert wird. Es können aber auch Kunststoffschichten aufgebracht werden, die ebenfalls daraufhin graviert werden.For use in gravure printing, a welded carrier sleeve 1, which is surface-treated as described above, is galvanized or sprayed all around, a metallic layer, preferably a copper alloy, which in turn is engraved in a subsequent step. Plastic layers can also be applied, which are then also engraved.

Zur Verwendung für den Offsetdruck als Trägerhülse 1 für eine Übertragungsform wird die gesamte oberflächenbearbeitete Hülsenoberfläche einschließlich der Verbindungsnaht 2 mit einem endlosen Gummischichtaufbau überdeckt, so daß von den drucktechnischen Eingenschaften aus betrachtet diese Gummituchhülsen identisch mit den üblichen Gummitüchern sind, jedoch mit diesen Gummmituchhülsen Endlos-Druck möglich ist.For use in offset printing as a carrier sleeve 1 for a transfer form, the entire surface-treated sleeve surface, including the connecting seam 2, is covered with an endless rubber layer structure, so that from a printing point of view, these blanket sleeves are identical to the usual blankets, but with these blanket sleeves, continuous printing is possible.

Die Art und Weise der Gummischicht ist abhängig vom jeweiligen Druckverfahren und unabhängig vom Material der Trägerhülsen.The type of rubber layer depends on the respective printing process and regardless of the material of the carrier sleeves.
