Die Erfindung betrifft eine Vorrichtung an Formzylinder einer Rotationsdruckmaschine zum Befestigen von mindestens zwei biegsamen Druckplatten.The invention relates to a device on forme cylinders a rotary printing machine for attaching at least two flexible printing plates.
Die nicht vorveröffentlichte deutsche Patentschrift Nr. 1 265 164 (die auf den Namen der Anmelderin lautet) zeigt eine Vorrichtung zum Befestigen von biegsamen Druckplatten auf Formzylindern von Rotationsdruckmaschinen mit zwei in einer Nut des Formzylinders angeordneten parallel zur Zylindermittelachse gegeneinander verschwenkbaren Spannbacken, an deren einander zugekehrte, einen engen Spalt bildende Spannflächen die Enden der Druckplatte, die an den bis nahe an die Zylindermantelfläche reichenden Kanten der Spannbacken abgewinkelt sind, mittels einer zwischen den Spannflächen angeordneten, sich länge der Spannbacken erstreckenden Klemmelementes preesbar sind, wobei jede Spannbacke an einem Ende des zweiarmigen Hebels angeordnet ist und zum Verschwenken der beiden Spannbacken gegeneinander am anderen Ende des die eine Spannbacke tragenden Hebel* eine eine Stellschraube und am anderen Ende des die andere Spannback.· tragenden Hebels ein federbelasteter Bolzen angreift. Di· Vorrichtung lat geeignet, ein· biegsame Druckplatt· auf den Formzylinder zu spannen, d«r«nThe unpublished German patent specification No. 1 265 164 (which is in the name of the applicant) shows a device for attaching flexible printing plates on forme cylinders of rotary printing machines with two clamping jaws which are arranged in a groove of the forme cylinder and can be pivoted against each other parallel to the cylinder center axis their facing, a narrow gap forming clamping surfaces the ends of the pressure plate, which are close to the The edges of the clamping jaws reaching the cylinder jacket surface are angled by means of a clamping element arranged between the clamping surfaces and extending along the length of the clamping jaws are preesbar, each clamping jaw is arranged at one end of the two-armed lever and for pivoting the two Clamping jaws against each other at the other end of the lever * carrying one clamping jaw, an adjusting screw and at the other A spring-loaded bolt engages the end of the lever carrying the other clamping jaw.

Länge annähernd dem Umfang des Formzylinders entspricht.Wurzburg
Length approximately corresponds to the circumference of the forme cylinder.
Durch dieses Patent ist kein Hinweis gegeben, wie vorgegangen werden muß, um zwei oder drei Druckplatten in Umfangsrichtung des Formzylinders mit den Vorteilen der Umfangsregistereinstellung und eines schmalen druckfreien Spaltes zu befestigen.This patent gives no indication of how to proceed around two or three printing plates in the circumferential direction of the forme cylinder with the advantages of the circumferential register setting and a narrow pressure-free gap to be attached.
Dies ist aber die Aufgabe des Gegenstandes der vorliegenden Erfindung.But this is the object of the subject matter of the present invention.
Durch diese Lösung wird der druckfreie Raum um die Breite des Steges und des zusätzlichen Klemmelementes verbreitert. Diese Verbreiterung ist jedoch relativ klein und gegenüber den Vorteilen der möglichen Registereinstellung und der im Vergleich zu anderen Plattenspannvorrichtungen einfachen Plattengestalt unbedeutend.With this solution, the pressure-free space is widened by the width of the web and the additional clamping element. However, this widening is relatively small and insignificant compared to the advantages of the possible register setting and the simple plate shape compared to other plate clamping devices.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und im folgenden näher erläutert. Es zeigt einen Querschnitt durch einen mit zwei Druckplatten belegten Formzylinder. An embodiment of the invention is shown in the drawing and explained in more detail below. It shows you Cross section through a forme cylinder covered with two printing plates.
Auf dem Formzylinder 1 sind zwei Druckplatten 2 und 4 auf gelegt. Sie werden durch die Spannbacken 21, 22 und 41, 42 gespannt. Zwischen den Spannbacken 21 und 42 befinden sich zwei Klemmeleinente in der Form elastischer Schnür· 23 und 44, On the forme cylinder 1, two printing plates 2 and 4 are placed on. They are clamped by the clamping jaws 21, 22 and 41, 42. Between the clamping jaws 21 and 42 there are two clamping elements in the form of elastic cord 23 and 44,

die an dem Steg k5, der am Formzylinder 1 befestigt ist, durch die Wirkung der Spannbacken angepresst werden.which are pressed against the web k5, which is attached to the forme cylinder 1, by the action of the clamping jaws.
Die Spannbacken 22 werden durch die am Hebel 28 sitzende Stellschraube 27 um die Achse 26 geschwenkt. Der Spannbacken 21 wird durch die Feder 29 betätigt, die ihn mit seinem Hebelarm 30 um die Achse 31 schwenkt. Bei Betätigung der Stellschraube 27 wird die elastische Schnur 2k zusammengedrückt und die Platte 2 gespannt. Dadurch wird die Feder 29 deformiert. Beim weiteren Anziehen der Stellschraube 27 kann die Platte 2 entgegen der Wirkrichtung der Feder* 29 ins Umfangsregister gebracht werden.The clamping jaws 22 are pivoted about the axis 26 by the adjusting screw 27 seated on the lever 28. The clamping jaw 21 is actuated by the spring 29, which pivots it with its lever arm 30 about the axis 31. When the adjusting screw 27 is actuated, the elastic cord 2k is compressed and the plate 2 is tensioned. This deforms the spring 29. If the adjusting screw 27 is tightened further, the plate 2 can be brought into the circumferential register against the direction of action of the spring * 29.
Die Teile der Spannvorrichtungen für die Platte K sind entsprechend den Teilen 21 bis 31 für die SpannvorrichtungThe parts of the clamping devices for the plate K are corresponding to the parts 21 to 31 for the clamping device
für die Platte 2 mit den Nummern 41 bis 51 bezeichnet.for the plate 2 with the numbers 41 to 51 designated.
