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 Forms of transmission from a metallic material whose The starting form is a rectangular, thin-walled plate piece that is brought into the desired hollow cylindrical shape by bending and the mutually facing edges of the plate piece firmly together are connected.

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.Nowadays it is well known from flexographic printing sleeve-shaped printing and transmission forms on galvanic produced nickel sleeves to apply. That way Printing and transfer forms produced are in a known manner by means of compressed air over a pressure cylinder core and then fixable by turning off the air supply. To this Carrier sleeves made of glass fiber reinforced were also used Plastic (GfK) or even carbon fiber reinforced plastic (CfK) used. The use of nickel GfK or even CFRP 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 is a sleeve-shaped Offset printing form has become known which consists of a rectangular cut metal plate is made by the one on top of the other facing edges of the plate connected by a weld will. The carrier sleeve produced in this way is except for the weld seam coated and exposed all around.

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 is a sleeve-shaped offset rubber blanket disclosed, also from a cut carrier plate a rubber layer is applied in the flat state is by including the beginning and end of the carrier plate Rubber layer are welded together.

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 transfer forms channel-free, but not endlessly printed, d. H. it can so that only finite printed products are produced. The stake an endless offset printing form is not yet known become.

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 comparatively inexpensive carrier sleeves for both printing and also to provide for forms of transmission through this one Endless 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 characterizing method steps of claim 8 solved.

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.With a carrier sleeve for printing and transfer forms from one metallic material, the starting form of which is a rectangular, is a thin-walled plate piece that is bent into the desired one Hollow cylindrical shape is brought and the mutually facing edges of the plate piece are firmly connected to each other, in which the Sleeve surface to form a homogeneous surface is processed so that continuous printing is feasible Nickel, GfK and CfK sleeves both under ecological, as well found an advantageous alternative from an economic point of view can be used universally 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 cost of a welded, according to the invention machined precision sleeve are many times lower than Manufacturing costs of galvanic nickel sleeves or even wound GRP or CFRP carrier sleeves, especially since it is becoming increasingly difficult will produce nickel sleeves galvanically as this Manufacturing processes involve 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 hergestellt sein. Furthermore, the carrier sleeves according to the invention depending on the respective Use case made of aluminum, steel, stainless steel, copper or Be made of brass.

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 mittels einer Schweißnaht 2 fest miteinander verbunden.1 shows an embodiment of a highly schematic Carrier sleeve 1 made of a metallic material, the aluminum, Can be steel, stainless steel or brass. The initial form is a rectangular, thin-walled plate piece, which by bending into the desired hollow cylindrical shape has been brought. The one on top of the other facing edges of the plate piece are by means of a Weld 2 firmly connected.

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 the carrier sleeve 1 quasi continuously to manufacture, as is done today with the pipe welding. The welding process itself is carried out using a laser beam performed. The precision sheets made of aluminum, steel, stainless steel, Copper or brass preferably have a wall thickness s of 0.1 up to 0.6 mm. The carrier sleeves can also be used with the DE 43 11 078 known welding device can be manufactured.

Die außenliegende Oberfläche der gesehweißten 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 welded carrier sleeve 1 is processed so that there is a homogeneous, continuous outer surface sets. When working on surfaces can be known Manufacturing processes such as turning, grinding or the like, with which one Metal surface becomes smooth, can be used. The original wall thickness of the thin-walled plate piece must be so be chosen so that the material removal from the outside 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 is how 3, on the outer surface of the sleeve 1 to provide a seam elevation 3 and in a following Process step to process them so that a continuous, endless surface on the surface of the carrier sleeve is created without that a removal of material 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 through targeted shielding gas guides, or by following the actual welding process Cladding reached.

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 The entire sleeve surface is then printed including the seam, in the present case a Weld 2, as already through the process steps in the Printing plate manufacture known, chemically roughened, anodized and provided with a final photosensitive layer. From seen from the printing properties, this is Printing form sleeve identical to the usual printing plates, except that continuous printing is possible with this printing form sleeve. Preferably aluminum sheets are 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 use an aluminum sleeve or one apply a water-bearing layer to another metallic sleeve, if the sleeve material itself is not water-bearing, but should be made water-bearing. As water-bearing layers can, for example, ceramic materials using thermal Spraying methods are applied.

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, especially for flexographic printing, this can be done welded precision sleeve 1, which also as described above is surface machined, directly as a carrier of a flexible Printing form, rubber stereo or engraved rubber printing form used and replaces the well-known nickel, GRP and CFRP 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 is welded onto a Carrier sleeve 1, which is surface-treated as described above, all around a metallic layer, preferably a copper alloy galvanized or sprayed, which in turn in a subsequent Work step is engraved. But it can also Plastic layers are applied, which then also be 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 The form of transmission is the entire surface-processed Sleeve surface including the connecting seam 2 with a Endless rubber layer structure covered, so that from the These blanket sleeves are considered from the printing properties are identical to the usual blankets, but with these Endless printing is possible with rubber sleeve.

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 particular one Printing process and regardless of the material of the carrier sleeves.
