Description

Die Erfindung betrifft eine Drucktucheinheit eines Drucktuchzylinders einer Druckmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a blanket unit of a blanket cylinder of a printing press according to the preamble of claim 1.

Drucktucheinheiten werden in Rotationsdruckmaschinen am Drucktuchzylinder befestigt und dienen beim Offsetdruck der Übertragung des Druckbilds vom Formzylinder auf die Bedruckstoffbahn. Um der Drucktucheinheit die erforderliche mechanische Festigkeit zu verleihen, wird eine Trägerplatte, beispielsweise aus Stahlblech oder Aluminiumblech, eingesetzt. Auf der Außenseite der Trägerplatte wird ein Drucktuch, das beispielsweise in der Art eines Gummituchs ausgebildet sein kann, befestigt. Zur Fixierung der Drucktucheinheit am Drucktuchzylinder sind am vorlaufenden Ende und/oder am nachlaufenden Ende der Trägerplatte abgekantete, drucktuchfreie Schenkel vorgesehen. Diese Schenkel können dann beispielsweise in einen am Drucktuchzylinder vorgesehenen Schlitz eingeführt und dort festgelegt werden.Blanket units are mounted in rotary printing presses on the blanket cylinder and are used in offset printing of the transfer of the print image from the forme cylinder to the printing substrate. In order to give the blanket unit the required mechanical strength, a support plate, for example made of sheet steel or aluminum sheet, is used. On the outside of the support plate, a blanket, which may be formed, for example, in the manner of a blanket attached. To fix the blanket unit on the blanket cylinder bent, blanket-free leg are provided at the leading end and / or at the trailing end of the carrier plate. These legs can then be introduced, for example, in a slot provided on the blanket cylinder and fixed there.

Ein Problem bei bekannten Drucktucheinheiten ist es, dass das Drucktuch die Trägerplatte nicht nahtlos umschließt, sondern zwischen dem vorlaufenden und dem nachlaufenden Ende des Drucktuchs ein Spalt verbleibt. Im Bereich diese Spalts kann keine Druckfarbe auf die Bedruckstoffbahn übertragen werden. An den Rändern des Drucktuchs zum Spalt hin ist zudem das Druckbild von schlechterer Qualität. Aus dem Stand der Technik sind deshalb verschiedene Lösungen bekannt, mit denen die durch den Spalt zwischen den Enden des Drucktuches hervorgerufenen Nachteile vermieden werden können.A problem with known blanket units is that the blanket does not seamlessly enclose the carrier plate, but leaves a gap between the leading and trailing ends of the blanket. In the area of this gap no ink can be transferred to the substrate web. At the edges of the blanket towards the gap is also the printed image of poorer quality. From the prior art, therefore, various solutions are known with which the disadvantages caused by the gap between the ends of the blanket can be avoided.

The outwardly facing end of the slide is connected to a filler, so that the gap between the ends of the blanket is closed by the filler.

Aus der DE 195 43 584 C1 ist eine Drucktucheinheit bekannt, bei der das Drucktuch aus einer Vielzahl von Lagen zusammengesetzt ist. Die Decklage überdeckt dabei die Stirnflächen der darunter befindlichen Lagen und bildet auf diese Weise einen Vorsprung, durch den der Spalt zwischen den Enden verkleinert wird.From the DE 195 43 584 C1 a printing blanket unit is known in which the blanket is composed of a plurality of layers. The cover layer covers the end faces of the underlying layers and thus forms a projection by which the gap between the ends is reduced.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.

Ein Vorteil der erfindungsgemäßen Drucktucheinheit liegt insbesondere darin, dass durch diese Drucktucheinheit, bei der eine Füllmasse an der Außenseite des Drucktuches in Längsrichtung des Drucktuches angeordnet ist, der Spalt zwischen den Enden des Drucktuches minimiert wird. Dabei ist es durchaus denkbar, dass der Überstand der Füllmasse so groß gewählt wird, dass die beiden Enden des Drucktuchs in der Einbauposition aneinander zur Anlage kommen.An advantage of the blanket unit according to the invention is in particular that by this blanket unit, in which a filling compound is arranged on the outside of the blanket in the longitudinal direction of the blanket, the gap between the ends of the blanket is minimized. It is quite conceivable that the supernatant of the filling compound is chosen so large that the two ends of the blanket come into contact with each other in the installed position.

Die Füllmassen, auch als Stützelemente bezeichnet, dienen zur Abstützung eines Gegenzylinders, insbesondere eines Formzylinders oder eines Plattenzylinders in radialer Richtung.The filling compounds, also referred to as supporting elements, serve to support a counter-cylinder, in particular a forme cylinder or a plate cylinder in the radial direction.

Für die Befestigung der Füllmasse an der Drucktucheinheit sind vielfältige Befestigungslösungen denkbar. Nach einer bevorzugten Ausführungsform ist die Füllmasse an der Abkantung und/oder an der Stirnseite des Drucktuchs stoffschlüssig befestigt, insbesondere festgeklebt oder anvulkanisiert.For the attachment of the filling compound to the blanket unit diverse fastening solutions are conceivable. According to a preferred embodiment, the filling compound is firmly bonded to the fold and / or on the front side of the blanket, in particular glued or vulcanized.

Besonders einfach lässt sich die Füllmasse herstellen, wenn sie aus dem gleichen Material wie das Drucktuch, beispielsweise aus Gummi oder einem ähnlichen Elastomermaterial, oder aus dem gleichen Material wie die Trägerplatte, beispielsweise Metall, hergestellt sind. Insbesondere ist es dann denkbar, die Füllmasse einstückig an das Drucktuch oder die Trägerplatte anzuformen.The filling compound can be produced in a particularly simple manner if they are produced from the same material as the printing blanket, for example made of rubber or a similar elastomer material, or from the same material as the carrier plate, for example metal. In particular, it is then conceivable to form the filling material in one piece to the blanket or the carrier plate.

Durch den Einsatz dieses Fertigungsverfahrens lassen sich in einfacher Weise Drucktucheinheiten herstellen, die nur einen minimalen Spalt aufweisen.By using this manufacturing method can be produced in a simple manner blanket units that have only a minimum gap.

Die Durchführung des Verfahrens erfolgt in einer Vorrichtung außerhalb der Druckmaschine, in der wenigstens die Trägerplatte mit bereits aufgebrachtem Drucktuch angeordnet ist. Die fließfähige Füllmasse wird in eine Form der Vorrichtung eingebracht, wo sie auf die Enden der Trägerplatte, an der mindestens ein Schenkel bereits abgewinkelt ist, aufgebracht wird.The method is carried out in a device outside the printing press, in which at least the support plate is arranged with already applied blanket. The flowable filling compound is introduced into a form of the device where it is applied to the ends of the carrier plate, on which at least one leg is already angled.

Die Füllmasse legt sich um die Abkantungen der Schenkel und wird durch die in der Vorrichtung angebrachten Schieber geformt. Anschließend wird die Füllmasse maßhaltig bearbeitet.The filling compound settles around the bends of the legs and is characterized by in the Device attached slider shaped. Subsequently, the filling material is processed dimensionally stable.

In einem alternativen Verfahren wird auf die mindestens ein abgewinkeltes Ende aufweisende Trägerplatte mit bereits aufgebrachtem Drucktuch im Bereich der Abkantung Füllnasse auf die Trägerplatte aufgebracht und mit einer Stirnseite des Endes des Drucktuches verbunden.In an alternative method is applied to the at least one angled end having carrier plate with already applied blanket in the region of the edge Füllnasse on the support plate and connected to an end face of the end of the blanket.

In einer anderen Ausführungsform weist die Drucktucheinheit mindestens ein Ende mit einer größeren Dicke als dem zwischen den beiden Enden liegenden Bereich auf, so dass die Außenfläche der Drucktucheinheit im Bereich dieses Endes in radialer Richtung zumindest teilweise über die virtuelle Verlängerung der Außenseite des Drucktuches übersteht.In another embodiment, the printing blanket unit has at least one end with a greater thickness than the region lying between the two ends, so that the outer surface of the blanket unit in the region of this end protrudes in the radial direction at least partially beyond the virtual extension of the outer side of the blanket.

Die in Fig. 1 bis Fig. 12 dargestellte Drucktucheinheit, deren Dicke d01 z. B. 1,6 mm beträgt, besteht aus einer formstabilen Trägerplatte 02; 18; 42, mit einer Dicke d02 von ca. 0,2 mm bis 0,5 mm und einem auf der Trägerplatte 02; 18; 42 befestigten Drucktuch 03; 19; 43. Die Trägerplatte 02; 18; 42 besteht aus Metall, beispielsweise aus einem Stahlblech oder Aluminium. Das Drucktuch 03; 19; 43 kann beispielsweise in der Art eines Gummituchs 03; 19; 43, insbesondere aus mehreren Lagen unterschiedlichem Materials, ausgebildet sein.In the Fig. 1 to Fig. 12 shown printing blanket unit whose thickness d01 z. B. 1.6 mm, consists of a dimensionally stable support plate 02; 18; 42, with a thickness d02 of about 0.2 mm to 0.5 mm and one on the support plate 02; 18; 42 attached blanket 03; 19; 43. The support plate 02; 18; 42 is made of metal, for example of a steel sheet or aluminum. The blanket 03; 19; 43, for example, in the manner of a blanket 03; 19; 43, in particular of several layers of different material, be formed.

In einer Abkantmaschine werden am vorlaufenden und am nachlaufenden Ende der Trägerplatte 02; 18; 42 die drucktuchfreien Schenkel 04; 06; 21; 22; 44; 46 nach unten abgekantet, so dass die Schenkel 04; 06; 21; 22; 44; 46 später zur Befestigung der Drucktucheinheit an einem Drucktuchzylinder 05 verwendet werden können. Der abgewinkelte Schenkel 06; 21; 46 am vorlaufenden Ende schließt mit der sich an den Schenkel 06; 21; 46 anschließenden Trägerplatte 02; 18; 42 einen spitzen Öffnungswinkel α06, insbesondere von 30 bis 60 Grad, vorzugsweise von 40 bis 50 Grad, ein. Der abgewinkelte Schenkel 04; 22; 44 am nachlaufenden Ende weist mit dem sich daran anschließenden Mittelteil 07; 35; 47 der Trägerplatte 02; 18; 42 einen Öffnungswinkel α04 von 45 bis 150 Grad, insbesondere von 80 bis 100 Grad, auf. In einer bevorzugten Ausführungsform beträgt die Winkelgröße 120 bis 150 Grad. Zwischen den Schenkeln 04, 06; 21; 22; 44; 46 verläuft der Mittelteil 07; 35; 47 der Trägerplatte 02; 18; 42, der vom Drucktuch 03; 19; 43 vollständig nach außen hin abgedeckt ist. Am Übergang zwischen dem Mittelteil 07; 35; 47 einerseits und den Schenkeln 04; 22; 44 bzw. 06; 21; 46 andererseits verlaufen die Abkantungen 08; 09; 27; 28; 48; 49.In a folding machine are at the leading and the trailing end of the support plate 02; 18; 42 the blanket-free leg 04; 06; 21; 22; 44; Folded down 46 so that the legs 04; 06; 21; 22; 44; 46 can be used later to attach the blanket unit to a blanket cylinder 05. The angled leg 06; 21; 46 at the leading end closes with the on the leg 06; 21; 46 subsequent support plate 02; 18; 42 an acute opening angle α06, in particular from 30 to 60 degrees, preferably from 40 to 50 degrees, a. The angled leg 04; 22; 44 at the trailing end points with the adjoining middle part 07; 35; 47 of the carrier plate 02; 18; 42 an opening angle α04 of 45 to 150 degrees, in particular from 80 to 100 degrees, on. In a preferred embodiment, the angular size is 120 to 150 degrees. Between the thighs 04, 06; 21; 22; 44; 46, the middle part 07 runs; 35; 47 of the carrier plate 02; 18; 42, of the blanket 03; 19; 43 is completely covered to the outside. At the transition between the middle part 07; 35; 47 on the one hand and the legs 04; 22; 44 or 06; 21; 46 on the other hand, the bends run 08; 09; 27; 28; 48; 49th

In der in Fig. 1 dargestellten Fertigungsphase sind sowohl die Trägerplatte 02 als auch das Drucktuch 03 annähernd eben ausgelegt, so dass das Drucktuch 03 spannungs- und verformungsfrei auf der Trägerplatte 02 befestigt werden kann. Dazu kann das Drucktuch 03 beispielsweise aufgeklebt und/oder aufvulkanisiert werden.In the in Fig. 1 The production phase shown, both the support plate 02 and the blanket 03 are designed approximately flat, so that the blanket 03 can be fixed tension and deformation on the support plate 02. For this purpose, the blanket 03, for example, glued and / or vulcanized.

Anschließend werden in einer Abkantmaschine die drucktuchfreien Schenkel 04 und 06 nach unten abgekantet (Fig. 2).Subsequently, in a folding machine, the blanket-free legs 04 and 06 are folded downwards ( Fig. 2 ).

Die Abkantungen 08 und 09 werden in der Abkantmaschine derart hergestellt, dass die beiden Enden 11 und 12 des Drucktuchs 03 ein stückweit über die Abkantungen 08 und 09 überstehen. Der Zwischenraum zwischen den überstehenden Enden 11 und 12 des Drucktuches 03 einerseits und der Trägerplatte 02 andererseits wird durch Füllmasse 13; 14, auch als Stützelement 13 und 14 bezeichnet, aufgefüllt. Die Füllmasse 13 und 14 kann beispielsweise durch Aufbringung einer härtbaren Gummimasse hergestellt werden.The folds 08 and 09 are produced in the bending machine such that the two ends 11 and 12 of the blanket 03 a piece far beyond the folds 08 and 09 survive. The space between the protruding ends 11 and 12 of the blanket 03 on the one hand and the support plate 02 on the other hand is filled by filling compound 13; 14, also referred to as support member 13 and 14, filled. The filling compound 13 and 14 can be produced for example by applying a curable rubber compound.

Vorzugsweise ist die Füllmasse 13; 14 beim Einbringen verformbar und/oder fliessfähig.Preferably, the filling compound 13; 14 deformable during insertion and / or flowable.

In Fig. 3 ist ein Ausschnitt der Drucktucheinheit in der Einbauposition dargestellt. Man erkennt, dass die beiden Schenkel 04 und 06 in der Einbauposition einander gegenüberliegend parallel zueinander verlaufen, so dass sie gemeinsam in einem Schlitz an einem nicht dargestellten Druckzylinder befestigt werden können. Aufgrund des Überstands der Enden 11 und 12 des Drucktuchs 03 wird die Breite des Spalts 16 zwischen den Enden 11 und 12 des Drucktuchs 03 minimiert. Dadurch ist es beispielsweise möglich, die Breite des Spalts 16 auf eine Breite von kleiner 0,5 mm zu minimieren.In Fig. 3 a section of the blanket unit is shown in the installed position. It can be seen that the two legs 04 and 06 extend in the installed position opposite each other parallel to each other, so that they can be fastened together in a slot on a pressure cylinder, not shown. Due to the projection of the ends 11 and 12 of the blanket 03, the width of the gap 16 between the ends 11 and 12 of the blanket 03 is minimized. This makes it possible, for example, to minimize the width of the gap 16 to a width of less than 0.5 mm.

Der Abstand der Abkantungen 08; 09 entspricht im wesentlichen dem Abstand a01 der Öffnung auf der Zylinderoberfläche und beträgt weniger als 3 mm, insbesondere ist er kleiner als 2,0 mm.The distance between the bends 08; 09 substantially corresponds to the distance a01 of the opening on the cylinder surface and is less than 3 mm, in particular it is smaller than 2.0 mm.

Aufgrund der Abstützung der überstehenden Enden 11 und 12 durch die Füllmasse 13 und 14 wird eine ausreichende Druckübertragung vom Drucktuch 03 auf eine Bedruckstoffbahn in diesem Bereich erreicht.Due to the support of the protruding ends 11 and 12 by the filling compound 13 and 14, a sufficient pressure transfer from the blanket 03 is achieved on a printing substrate in this area.

Wie in Fig. 4 dargestellt, beträgt der Abstand a02 der gegenüberliegenden Enden 11; 12 des Drucktuchs 03 0,2 mm bis 0,8 mm, vorzugsweise 0,3 mm bis 0,7 mm. In einer besonders bevorzugten Ausführung beträgt der Abstand a02 0,4 mm bis 0,6 mm, insbesondere 0,5 mm.As in Fig. 4 illustrated, the distance a02 of the opposite ends 11; 12 of the blanket 03 0.2 mm to 0.8 mm, preferably 0.3 mm to 0.7 mm. In a particularly preferred embodiment, the distance a02 is 0.4 mm to 0.6 mm, in particular 0.5 mm.

Die Abkantung 08 des Schenkels 04 weist einen Radius R von 0,6 mm bis 1,2 mm, insbesondere von 0,8 mm, auf.The fold 08 of the leg 04 has a radius R of 0.6 mm to 1.2 mm, in particular of 0.8 mm.

Die Abkantung 09 des Schenkels 06 weist hingegen einen Radius R von 0,3 mm bis 0,7 mm, insbesondere von 0,5 mm, auf.The bevel 09 of the leg 06, however, has a radius R of 0.3 mm to 0.7 mm, in particular of 0.5 mm.

Die Länge L13; L14 des jeweiligen Stützelements 13; 14 beträgt in Umfangsrichtung 0,4 mm bis 1,0 mm, insbesondere 0,1 mm bis 1,3 mm. In einer bevorzugten Ausführung liegt die Länge L13; L14 des Stützelements 13; 14 bei 0,7 mm.The length L13; L14 of the respective support element 13; 14 is in the circumferential direction 0.4 mm to 1.0 mm, in particular 0.1 mm to 1.3 mm. In a preferred embodiment, the length L13; L14 of the support member 13; 14 at 0.7 mm.

Wie in Fig. 4 dargestellt, kann die Füllmasse 13; 14 in unterschiedlicher Gestalt ausgeformt sein. So weist die Füllmasse 13 z. B. einen spitzen Winkel auf, während die Füllmasse 14 rechtwinklig ausgeformt ist.As in Fig. 4 illustrated, the filling compound 13; 14 may be formed in different shapes. Thus, the filling material 13 z. B. an acute angle, while the filling material 14 is formed at right angles.

Die für die Fig. 4 beschriebenen Maße können im Wesentlichen auf sämtliche in den Figuren dargestellte Ausführungsformen übertragen werden.The for the Fig. 4 described dimensions can be transferred substantially to all embodiments shown in the figures.

In Fig. 5 ist eine dritte Ausführungsform einer Drucktucheinheit dargestellt. Auch diese Drucktucheinheit weist eine Trägerplatte 18 aus Stahlblech und ein Drucktuch 19 aus Gummi auf. Zur Herstellung der Drucktucheinheit wird zunächst die Trägerplatte 18 mit deren Schenkeln 21 und 22 an einem Fertigungszylinder befestigt, dessen Gestalt dem Drucktuchzylinder entspricht, an dem die Drucktucheinheit in der Druckmaschine befestigt werden soll. Anschließend wird ein Dichtungselement 23 in den Spalt 26 zwischen den Schenkeln 21 und 22 eingelegt, um den Spalt 26 nach unten abzudichten. Danach wird eine flüssige Elastomermasse an der Außenseite der Trägerplatte 18 derart aufgebracht, dass die Trägerplatte 18 von einer durchgehenden Unterbauschicht 24 umgeben wird. Im Bereich der gegenüberliegenden Schenkel 21 und 22 füllt die Unterbauschicht 24 den Spalt 26 zwischen den gegenüberliegenden Abkantungen 27 und 28 aus.In Fig. 5 a third embodiment of a blanket unit is shown. These too Blanket unit comprises a support plate 18 made of sheet steel and a blanket 19 made of rubber. To produce the printing blanket unit, the support plate 18 is first attached with its legs 21 and 22 to a production cylinder, the shape of which corresponds to the blanket cylinder to which the blanket unit is to be fastened in the printing press. Subsequently, a sealing member 23 is inserted into the gap 26 between the legs 21 and 22 to seal the gap 26 down. Thereafter, a liquid elastomer composition is applied to the outside of the support plate 18 such that the support plate 18 is surrounded by a continuous Unterbauschicht 24. In the region of the opposite legs 21 and 22, the sub-base layer 24 fills the gap 26 between the opposite folds 27 and 28.

Anschließend wird auf der Unterbauschicht 24 das Drucktuch 19 befestigt, beispielsweise aufvulkanisiert. Der Spalt 26, der sich zwischen den Enden 31 und 32 des Drucktuchs 19 fortsetzt, wird mit Füllmaterial, hier auch als Siegelmaterial 29 bezeichnet, beispielsweise einer härtbaren Elastomermasse, verschlossen und anschließend an der Außenseite zur Herstellung einer gleichmäßig zylindrischen Außenfläche überschliffen.Subsequently, the blanket 19 is attached to the base layer 24, for example, vulcanized. The gap 26, which continues between the ends 31 and 32 of the blanket 19, is closed with filling material, here also referred to as sealing material 29, for example, a curable elastomer composition, closed and then ground on the outside to produce a uniform cylindrical outer surface.

Zum Schluss wird das Siegelmaterial 29 und die Unterbauschicht 24 entlang der Schnittlinie 33 durchtrennt, so dass die Drucktucheinheit vom Fertigungszylinder abgenommen und an einem Drucktuchzylinder montiert werden kann. Durch die Trennung der Unterbauschicht 24 werden getrennte Stützelemente 34 und 36 gebildet, die jeweils die Enden 31 und 32 des Drucktuchs 19 von unten abstützen. Bei Montage der Drucktucheinheit an einem Drucktuchzylinder können die durch den Schnitt entlang der Schnittlinie 33 gebildeten Seitenflächen der Stützelemente 34 und 36 formschlüssig aneinander zur Anlage kommen.Finally, the sealing material 29 and the subgrade layer 24 are severed along the cutting line 33, so that the printing blanket unit can be removed from the production cylinder and mounted on a blanket cylinder. By separating the base layer 24 separate support members 34 and 36 are formed, each of which supports the ends 31 and 32 of the blanket 19 from below. When mounting the printing blanket unit on a blanket cylinder, the side surfaces of the support elements 34 and 36 formed by the cut along the section line 33 can come into positive engagement with one another.

Die Figuren 6 bis 8 zeigen Ausführungsbeispiele eines anderen Herstellungsverfahrens für eine Drucktucheinheit ähnlich der der Fig. 3.The FIGS. 6 to 8 show embodiments of another manufacturing method for a blanket unit similar to that of Fig. 3 ,

Hier wird mindestens ein Ende der Trägerplatte 42, wie bereits beschrieben, abgewinkelt. Die Trägerplatte 42 wird nun auf einen Grundkörper 53 einer Vorrichtung 41 mit mindestens einem Schieber 54; 56, wie sie nachfolgend noch beschrieben wird, aufgelegt. Mindestens einer der Schieber 54; 56 ist zum Grundkörper 53 und/oder zum anderen Schieber 56; 54 beweglich. Dieser Grundkörper 53 ist in seiner Geometrie der Geometrie der Trägerplatte 42 angepasst. Beide Schieber 54; 56 der Vorrichtung 41 sind offen. Die Trägerplatte 42 wird nun auf den notwendigen Zylinderumfang bzw. auf das notwendige Abkantmaß mittels eines Einstellmechanismus 57 eingestellt. Beide Schieber 54; 56 werden geschlossen. Die Füllmasse 51; 52 wird anschließend formschlüssig eingegossen bzw. eingepresst. Je nach Form der Schieber 54; 56 wird ein flacher, d. h. mit der Trägerplatte 42 bündiger, bzw. ein erhöhter Unterbau erreicht, wobei die Schieber 54; 56 als Form 54; 56 für die Füllmasse 51; 52 wirken. Zumindest eine der Füllmassen 51; 52 steht dabei über die virtuelle Verlängerung V42 der Außenseite der Trägerplatte 42 in radialer Richtung hinaus. Die Füllmasse 51; 52 wird nun durch eine weitere Vorrichtung 58 bündig gezogen bzw. geschliffen. Anschließend wird das Drucktuch 43 auf die Füllmasse 51; 52 aufgebracht. Dies kann mit Hilfe eines anstellbaren Anschlages 59 erfolgen. Zum Schluss werden die Schieber 54; 56 geöffnet und die Drucktucheinheit wird vulkanisiert. Diese Vulkanisierung kann innerhalb der Vorrichtung 41, aber auch außerhalb der Vorrichtung 41 durchgeführt werden.Here, at least one end of the support plate 42, as already described, angled. The support plate 42 is now on a base 53 of a device 41 with at least one slider 54; 56, as described below, launched. At least one of the sliders 54; 56 is the main body 53 and / or the other slider 56; 54 mobile. This basic body 53 is adapted in its geometry to the geometry of the carrier plate 42. Both slides 54; 56 of the device 41 are open. The carrier plate 42 is then adjusted to the necessary cylinder circumference or to the necessary Abkantmaß means of an adjustment mechanism 57. Both slides 54; 56 are closed. The filling compound 51; 52 is then poured or pressed positively. Depending on the shape of the slider 54; 56 is a flat, ie flush with the support plate 42, or achieved a raised base, wherein the slide 54; 56 as form 54; 56 for the filling material 51; 52 act. At least one of the filling compounds 51; 52 stands on the virtual extension V42 of the outside of the support plate 42 in the radial direction addition. The filling compound 51; 52 is then pulled flush by a further device 58 or ground. Subsequently, the blanket 43 to the filling material 51; 52 applied. This can be done by means of an engageable stop 59. Finally, the slides 54; 56 is opened and the blanket unit is vulcanized. This vulcanization can be carried out within the device 41, but also outside the device 41.

Die Figuren 9 und 10 zeigen ein besonders bevorzugtes Herstellungsverfahren für eine weitere Drucktucheinheit. Diese Ausführung einer Drucktucheinheit ermöglicht es, einen Kanal eines Zylinders zu verschließen und zu verstärken.The FIGS. 9 and 10 show a particularly preferred manufacturing method for another blanket unit. This embodiment of a blanket unit makes it possible to close and reinforce a channel of a cylinder.

Die Füllmasse 51; 52 erstreckt sich hier an einer virtuellen Verlängerung V43 der Außenseite des Drucktuches 43 in Längsrichtung, d. h. Umfangsrichtung, des Drucktuches 43. Dabei kann die Füllmasse 51; 52 sowohl über ein Ende 61; 62 als auch über beide Enden 61; 62 des Drucktuches 43 in Längsrichtung hinausragen. In radialer Richtung kann die Füllmasse 51; 52 zumindest teilweise über die virtuelle Verlängerung V43 der Außenseite des Drucktuches 43 überstehen (Fig. 10 und 11).The filling compound 51; 52 extends here at a virtual extension V43 of the outside of the blanket 43 in the longitudinal direction, ie circumferential direction, of the blanket 43. In this case, the filling material 51; 52 both over an end 61; 62 and over both ends 61; 62 of the blanket 43 protrude in the longitudinal direction. In the radial direction, the filling compound 51; 52 at least partially beyond the virtual extension V43 of the outside of the blanket 43 survive ( 10 and 11 ).

Diese Ausführungsform wird durch folgendes Herstellungsverfahren erreicht. Wie bereits beschrieben, wird mindestens ein Ende der Trägerplatte 42 abgekantet. Anschließend wird das Drucktuch 43 auf die Trägerplatte 42 aufgebracht. Unerheblich dabei ist, ob das Drucktuch 43 bereits vulkanisiert ist oder nicht. Die Schieber 54; 56 werden anschließend geschlossen. Die Füllmasse 51; 52 zum Verschließen und Verstärken eines Kanals wird nun eingepresst bzw. eingegossen. Je nach dem wie die Schieber 54; 56 ausgebildet sind, wird eine entsprechende Formgebung der Füllmasse 51; 52 erreicht. Danach wird die Füllmasse 51; 52 maßhaltig bearbeitet. Anschließend kann, je nach Bedarf, der Vulkanisierungsvorgang innerhalb oder außerhalb der Vorrichtung 41 stattfinden.This embodiment is achieved by the following manufacturing method. As already described, at least one end of the support plate 42 is bent. Subsequently the blanket 43 is applied to the carrier plate 42. It is irrelevant whether the blanket 43 is already vulcanized or not. The sliders 54; 56 are then closed. The filling compound 51; 52 for closing and reinforcing a channel is now pressed or poured. Depending on how the slider 54; 56 are formed, a corresponding shape of the filling material 51; 52 reached. Thereafter, the filling compound 51; 52 dimensionally processed. Subsequently, as needed, the vulcanization process can take place inside or outside the device 41.

Die beiden letztgenannten Herstellungsverfahren unterscheiden sich also dadurch, dass in den Ausführungen gemäß den Figuren 6 bis 8 die Füllmasse 51; 52 zwischen der Trägerplatte 42 und dem Drucktuch 43 angeordnet ist, wobei die Füllmasse 51; 52 zuerst auf die Trägerplatte 42 und dann das Drucktuch 43 angeordnet ist, während in den Ausführungen gemäß den Figuren 9 bis 11 die Trägerplatte 42 mit dem Drucktuch 43 verbunden ist und dann die Füllmasse 51; 52 eingefüllt wird, wobei eine in radialer Richtung angeordnete Außenseite der Füllmasse 51; 52 nicht vom Drucktuch 43 belegt ist.The two latter production methods thus differ in that in the embodiments according to the FIGS. 6 to 8 the filling material 51; 52 is disposed between the support plate 42 and the blanket 43, wherein the filling material 51; 52 is disposed first on the support plate 42 and then the blanket 43, while in the embodiments according to the FIGS. 9 to 11 the carrier plate 42 is connected to the blanket 43 and then the filling material 51; 52 is filled, wherein a radially arranged outside of the filling material 51; 52 is not occupied by the blanket 43.

Wie in den Figuren 8, 11 und 12 dargestellt, weist die Drucktucheinheit mindestens ein Ende mit einer größeren Dicke als dem zwischen den beiden Enden liegenden Bereich auf, so dass die Außenfläche der Drucktucheinheit im Bereich dieses Endes in radialer Richtung zumindest teilweise über die virtuelle Verlängerung V43 der Außenseite des Drucktuches 43 übersteht, insbesondere keilförmig ausgebildet ist. Zur Verdickung des Endes ist die Füllmasse 51; 52 an den Enden des Drucktuches 43 angeordnet. In den Figuren 8 und 12 ist dabei eine Unterfütterung des Drucktuches zu 43 erkennen, wobei in Fig. 11 eine Auffüllung des Drucktuches 43 dargestellt ist.As in the FIGS. 8 . 11 and 12 illustrated, the blanket unit at least one end with a greater thickness than the lying between the two ends region, so that the outer surface of the blanket unit in the region of this end in the radial direction at least partially beyond the virtual extension V43 the outside of the blanket 43, in particular is wedge-shaped. To thicken the end of the filling material 51; 52 arranged at the ends of the blanket 43. In the FIGS. 8 and 12 is a relining of the blanket to 43 recognize, in Fig. 11 a filling of the blanket 43 is shown.

Die Ausführung mit verdickten Enden der Fig. 8 im auf dem Zylinder montierten Zustand gilt entsprechend auch für Fig. 11.The version with thickened ends of the Fig. 8 in the mounted on the cylinder state applies accordingly also for Fig. 11 ,
