Description

Die Erfindung bezieht sich auf eine Rotationsgummidruckmaschine zum beiderseitigen Bedrucken von Papierbahnen, die sich gegenüber bekannten Maschinen dieser Art dadurch kennzeichnet, daß die Druckformen durch zwei übertragungszylinder nacheinander an zwei Stellen je zur Hälfte in gleichzeitigem Schön- und Widerdruck abgedruckt werden. Die Ausführungsform der Maschine ist vorteilhaft die, daß in jedem Druckwerk zwei Umdruckzylinder um einen gemeinsamen gleich großen Plattenzylinder angeordnet sind. Es sind einerseits Rotationsgummidruckmaschinen zum beiderseitigen Bedrucken einer endlosen Papierbahn bekannt, bei denen für jeden Plattenzylinder ein Umdruckzylinder vorgesehen ist, der vollständig mit Gummituch bespannt ist und die Formrläche restlos vorn Plattenzylinder abnimmt und auf die Papierbahn überträgt. Anderseits sind Rotationsgummidruckmaschinen zum Bedrucken von Einzelbogen bekannt, welche zwei Umdruckzylinder an einein gemeinsamen, um ein Vielfaches größeren Plattenzylinder aufweisen. Demgegenüber wird durch die vorliegende Erfindung einem lange vorliegenden Bedürfnis nach einer einfachen, ohne Zuhilfenahme von Regelvorrichtungen genaues Register haltenden Gummidruckmaschine für endlose Bahnen im Schön- und Widerdruck Rechnung getragen. Man erhält nicht nur den Vorteil der Verwendung von nur halb großen Gummitüchern, sondern es können auch den Umdruckzylindern breite Kanäle gegeben werden, so daß das Aufbringen der Gummitücher wesentlich vereinfacht ist, und der Plattenzylinder ist nur ebenso groß wie die übertragungszylinder, so daß die Maschine entsprechend leicht gebaut werden kann.The invention relates to a rotary rubber printing machine for both sides Printing of paper webs, which is different from known machines of this type indicates that the printing plates are successively attached by two transfer cylinders two places each half printed in simultaneous front and back printing. The embodiment of the machine is advantageous that two in each printing unit Transfer cylinders are arranged around a common plate cylinder of the same size. On the one hand, there are rotary rubber printing machines for printing on both sides endless paper web known in which a transfer cylinder for each plate cylinder is provided, which is completely covered with rubber blanket and the molding surface completely decreases in front of the plate cylinder and transfers it to the paper web. On the other hand, there are rotary rubber printing machines known for printing individual sheets, which two transfer cylinders to one in common to one Have plate cylinders many times larger. In contrast, the present Invention to a long-felt need for a simple, no-help rubber printing machine for endless webs in front and back printing, keeping precise register with regulating devices Taken into account. Not only does one get the benefit of using only half-sized ones Blankets, but wide channels can also be given to the transfer cylinders, so that the application of the blankets is significantly simplified, and the plate cylinder is just as big as the transfer cylinder, so the machine accordingly can be easily built.

In der Zeichnung ist die neue Maschine in beispielsweiser Ausführungsform schematisch dargestellt. P ist die endlose Papierbahn, A und B sind die Plattenzylinder, auf deren Oberfläche die geätzte Formplatte liegt, welche durch die Feuchtwerke Wa und Wb angefeuchtet und durch die Farbwerke Fa und Fh eingefärbt wird. Va1 und Ub1 bzw. Ua" und Ub2 sind die zusammenarbeitenden Übertragungszylinderpaare. Jeder Plattenzylinder ist ebenso groß wie die zugehörigen Übertra- 5« gungszylinder, und von diesen nimmt ein Jeder eine seiner elastischen Fläche entsprechende Fonnhälfte des zugehörigen Plattenzylinders auf und überträgt sie auf die endlose Papierbahn. Zur besseren Bedienung der Plattenzylinder A und B sind die Farbwerke Fa und Fb abfahrbar eingerichtet.In the drawing, the new machine is shown schematically in an exemplary embodiment. P is the endless paper web, A and B are the plate cylinders, on the surface of which lies the etched form plate, which is moistened by the dampening units Wa and Wb and colored by the inking units Fa and Fh. Va 1 and Ub 1 or Ua " and Ub 2 are the cooperating transfer cylinder pairs. Each plate cylinder is the same size as the associated transfer cylinder, and each of these takes up one half of the associated plate cylinder corresponding to its elastic surface and transfers it For better operation of the plate cylinders A and B , the inking units Fa and Fb are set up so that they can be moved.
