Zylinder für Druckmaschinen.Cylinders for printing machines.

Die Neuerung betrifft Zylinder für Druckmaschinen.The innovation concerns cylinders for printing machines.

Druckzylinder werden vorwiegend im Gießverfahren aus Eisenwerkstoffen oder aus Aluminiumlegierungen hergestellt. Im zylindrischen Bereich werden die Zylinder zur Erzielung eines gleichmäßigen Druckes mit größter Genauigkeit meistens durch !Feinschleifen bearbeitet. Es kann sich hierbei z.B. um Plattenzylinder Tuchzylinders Gegendruckzylinder usw. handeln.Printing cylinders are mainly made from ferrous materials in the casting process or made from aluminum alloys. In the cylindrical area, the cylinders are used to achieve a even pressure with the greatest accuracy, mostly processed by fine grinding. It can be a plate cylinder, for example Acting blanket cylinder, impression cylinder, etc.

Durch Hineinfallen von Fremdkörpern werden Druckzylinder oft an ihrer zylindrischen Oberfläche beschädigt, so daß sie unbrauchbar werden. Besonders empfindlich gegen Oberflächenbeschädigungen sind Druckzylinder aus Aluminiumlegierungen.By falling in of foreign bodies, printing cylinders are often damaged on their cylindrical surface, so that they are unusable will. Printing cylinders made of aluminum alloys are particularly sensitive to surface damage.

Bei kleineren Beschädigungen hat man mit Erfolg die Oberflächenunebenheiten mit Kunststoff ausgekleidet und anschließend örtlich bearbeitet. Bei stärkeren Beschädigungen erhalten die Zylinder außer den Oberflächenunebenheiten Störungen im Rundlauf, so daßIn the case of minor damage, the surface unevenness is successful Lined with plastic and then processed locally. In the event of more severe damage, the cylinders receive except for the surface irregularities disturbances in the concentricity, so that

local repairs are no longer successful.

leuerungsgemäß wird vorgeschlagen,beschädigte Zylinder (l), insbesondere aus -Aluminiumguß, nach dem Ausbau aus der Druckmaschine auf Untermaß abzudrehen und mit einer neuen Schicht (2), vorteilhaft aus Metall, zu ersetzen. Diese Maßnahme führt gleichzeitig zur Verbesserung von Druckzylindern, gegenüber ihrem ursprünglichen Zustand. Aluminiumzylinder mit einer sehr weichen Oberfläche werden nach dem Aufbringen einer Oberflächenschicht, von,. z.B. Chromstahl, sehr hart und unempfindlich. Sie erzielen einen ausgezeichneten Druck, ohne auf die Leichtbauweise der Zylinder mit ihren Vorteilen verzichten zu müssen. Vorteilhaft werden die Oberflächenschichten wärmearm durchAccording to the proposal, damaged cylinder (l), in particular Made of cast aluminum, after removing it from the printing machine, turn it down to undersize and apply a new layer (2), advantageously Metal, to replace. This measure also leads to an improvement in printing cylinders compared to their original condition. Aluminum cylinders with a very soft surface are after the application of a surface layer of ,. e.g. chrome steel, very hard and insensitive. You achieve excellent pressure without having to forego the lightweight construction of the cylinders and their advantages to have to. The surface layers are advantageously low in heat
