Description

Die Erfindung betrifft ein Drucktuch zur Verwendung auf Druckzylindern für insbesondere Offset-Druckmaschinen nach dem Oberbegriff des Anspruchs 1.The invention relates to a blanket for use on printing cylinders for in particular offset printing machines according to the preamble of claim 1.

Aus dem Patent Abstract of Japan der japanischen Patentanmeldung 58084294 mit der Publikationsnummer 59209198 ist ein mehrschichtiges Drucktuch, dessen Trägerlage, die auf den Druckzylinder einer Offset-Druckmaschine aufgelegt und mit ihren Enden in den Spannkanal eingesetzt wird, eine metallische Unterlage ist. Auf diesem Metallblech ist in gestreckter Form der mehrschichtige Drucktuchaufbau aufgebracht und anvulkanisiert.From the Patent Abstract of Japan the Japanese Patent Application 58084294 with the publication number 59209198 is a multi-layered blanket, the carrier layer, which is placed on the printing cylinder of an offset printing machine and inserted with their ends in the clamping channel, a metallic pad. The multilayer printing blanket construction is applied in stretched form to this metal sheet and vulcanized.

Um die Enden dieses eine metallische Trägerlage aufweisenden Drucktuchs (Metalldrucktuch) in den Einspannkanal einzusetzen, ist es aus der EP 0 884 176 A1 bekannt, die Enden des Drucktuchs während der Herstellung bereits frei von dem Drucktuchaufbau zu belassen. Die Enden der Trägerlage werden abgeknickt und in den Einspannkanal der Offsetdruckmaschine eingebracht und dort festgespannt.In order to insert the ends of this a metallic carrier layer having printing blanket (metal blanket) in the clamping channel, it is from the EP 0 884 176 A1 It is known to leave the ends of the printing blanket free of the blanket structure during manufacture. The ends of the carrier layer are bent and introduced into the clamping channel of the offset printing machine and clamped there.

Der Erfindung liegt die Aufgabe zugrunde, ein Drucktuch der eingangs geschilderten Art derart auszugestalten, dass es den Druckzylinder mechanisch nicht schädigt und dass keinerlei Korrosion aufgrund der unterschiedlichen Metallpaarungen entstehen kann. Weiter soll das feste Sitzen des Metalldrucktuchs auf dem Druckzylinder verbessert werden.The invention has the object of providing a blanket of the type described in such a way that it does not mechanically damage the printing cylinder and that no corrosion due to the different metal pairings can arise. Next, the firm sitting of the metal blanket is to be improved on the printing cylinder.

Der Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 genannten Merkmale gelöst.The object is achieved by the features mentioned in the characterizing part of claim 1.

Durch die beidseitige Beschichtung des Metallblechs mit thermoplastischem oder elastomerem Werkstoff wird die Korrosionsgefahr zwischen metallischer Trägerlage und Druckzylinder minimiert. Die Beschichtung auf der Oberseite der metallischen Trägerlage erleichtert die Anbindung an die kompressible elastomere Zwischenschicht.The two-sided coating of the metal sheet with thermoplastic or elastomeric material minimizes the risk of corrosion between the metallic carrier layer and the impression cylinder. The coating on the top of the metallic carrier layer facilitates the connection to the compressible elastomeric intermediate layer.

In dem Drucktuch nach Anspruch 1 erstreckt sich die Beschichtung über die gesamte Länge des Metallblechs. Dadurch kann die Beschichtung nicht durch Farbe oder Waschmittel unterwandert werden. Die Ablösung der Beschichtung ist weitgehend verhindert. Die Beschichtung ist auch auf den abgeknickten Enden des Metallblechs und führt somit bis in den Einspannkanal des Druckzylinders.In the blanket according to claim 1, the coating extends over the entire length of the metal sheet. As a result, the coating can not be infiltrated by paint or detergent. The detachment of the coating is largely prevented. The coating is also on the bent ends of the metal sheet and thus leads into the clamping channel of the printing cylinder.

Eine vorteilhafte Ausgestaltung der Erfindung wird gemäß Anspruch 2 gekennzeichnet. Der Werkstoff Polyamid eignet sich zur Anbindung einerseits an die elastomeren Schichten des Drucktuchs und ergibt andererseits eine gute Beständigkeit hinsichtlich der metallischen Oberfläche des Druckzylinders.An advantageous embodiment of the invention is characterized according to claim 2.

Die Erfindung betrifft auch ein Verfahren zur Herstellung eines Drucktuches nach dem Oberbegriff des Anspruchs 3. Das Verfahren wird im Kennzeichens des Anspruchs 3 offenbart. Das Laminat wird aus einer Metallblechbahn, die mit thermoplastischem oder elastomerem Werkstoff beschichtet wird, kontinuierlich hergestellt. Dann wird eine mehrschichtige Drucktuchaufbaubahn auf die Laminatschicht aufgebracht. In bestimmten Abständen wird dann der Drucktuchaufbau quer zur Bahnlängsrichtung über die gesamte Breite senkrecht bis zur oberen Beschichtung eingeschnitten. Die dabei entstehenden Abschnitte des Drucktuchaufbaus sind so bemessen, dass jeder zweite Abschnitt der Länge zweier Einspannenden entspricht. Anschließend werden der bestehende Drucktuchaufbau und die Laminatschicht durch Vulkanisation verbunden, wobei die obere Beschichtung als Haftvermittler wirkt.The invention also relates to a method for producing a printing blanket according to the preamble of claim 3. The method is disclosed in the characterizing part of claim 3. The laminate is made continuously from a sheet metal sheet which is coated with thermoplastic or elastomeric material. Then, a multilayer blanket sheet is applied to the laminate layer. At certain intervals, the blanket structure is then cut transversely to the web longitudinal direction over the entire width perpendicular to the upper coating. The resulting sections of the blanket structure are dimensioned so that every other section corresponds to the length of two clamping ends. Subsequently, the existing blanket structure and the laminate layer are bonded by vulcanization, wherein the upper coating acts as a bonding agent.

Anschließend werden durch Abschneiden einzelne Drucktücher erzeugt.Subsequently, individual blankets are produced by cutting.

In vorteilhafter Ausgestaltung des erfindungsgemäßen Verfahrens ist der Drucktuchaufbau vor dem Aufbringen auf die Trägerschicht mit einem kaltklebenden Haftvermittler auf seiner Unterseite versehen.In an advantageous embodiment of the method according to the invention, the printing blanket structure is provided with a cold-adhesive bonding agent on its underside prior to application to the carrier layer.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens wird im Anspruch 5 offenbart. Der in Bahnform vorliegende Drucktuchaufbau, der auf der Trägerschicht aufgeklebt worden ist, kann in Abständen so zur oberen Beschichtung eingeschnitten werden, dass jede zweite Abstandslänge durch Abziehen des jeweiligen Drucktuchaufbauschnitts freigelegt wird, wobei die Abstandslänge vorteilhafter Weise der Länge zweier Einspannenden entspricht.A further advantageous embodiment of the method according to the invention is disclosed in claim 5. The sheet-form blanket construction which has been adhered to the backing layer may be cut at intervals to the topcoat such that every other pitch length is exposed by peeling off the respective blanket blank, the pitch length advantageously corresponding to the length of two blanket ends.

Das Verfahren gemäß Anspruch 6 sieht vor, dass bereits vereinzelte längenbegrenzte Drucktuchaufbauten in Abständen auf die Trägerschicht aufgebracht und zusammen mit der Trägerschicht vulkanisiert werden.The method according to claim 6 provides that already isolated length-limited blanket structures are applied at intervals to the carrier layer and vulcanized together with the carrier layer.

Dieser Drucktuchaufbau 1, 2, 3 ist auf einer aus einem Laminat bestehenden, nicht dehnbaren Trägerschicht 4 fest aufgebracht, z.B.aufvulkanisiert. Die Laminatschicht 4 besteht aus einem stabilen, aber biegsamen Metallblech 5, das beidseitig mit jeweils einer aus Polyamid bestehenden Kunststofffolie 6 und 7 beschichtet ist. Die Laminatschicht 4 ragt in Längsrichtung über die Länge des Drucktuchaufbaus 1, 2, 3 unter Bildung von Enden 8 und 9 hinaus.This in Fig.1 shown blanket has a structure of an elastomeric printing layer 1, an underlying fabric layer 2 and connected to the fabric layer 2, microporous elastomeric intermediate layer 3. This blanket structure 1, 2, 3 is firmly applied, for example vulcanized, to a non-stretchable carrier layer 4 consisting of a laminate. The laminate layer 4 consists of a stable, but flexible metal sheet 5, which is coated on both sides with each one consisting of polyamide plastic film 6 and 7. The laminate layer 4 protrudes in the longitudinal direction over the length of the blanket structure 1, 2, 3 with the formation of ends 8 and 9.
