Unser Zeichen: R 1248 EPOur reference: R 1248 EP PatentansprüchePatent claims 1. Druckzylinder, enthaltend in Kombination:1. Printing cylinder containing in combination: a) einen Längsschlitz in seiner Oberflache zur Bildung wenigstens einer hinterschnxttenen Sperrfläche, gegen die beide Enden einer flexiblen Druckplatte geklemmt sind, damit die Platte sicher gegen die Oberfläche des Zylinders gehalten wird;a) a longitudinal slot in its surface to form at least one undercut locking surface against which both ends of a flexible pressure plate are clamped so that the plate is held securely against the surface of the cylinder; b) ein Sperrmittel mit einer gekrümmten Außenfläche zum Berühren der Enden der flexiblen Platte und zu deren Festklemmen gegen die hinterschnittene Sperrfläche;b) a locking means having a curved outer surface for contacting the ends of the flexible sheet and clamping them against the undercut locking surface; c) Federvorspannmittel, die mit wirksamem Druck zwischen dem Sperrelement und dem Boden des Längsschlitzes angeordnet sind, damit die gekrümmte Außenfläche des Sperrelements nach außen gegen die hinterschnittene Sperrfläche gedrückt wird.c) spring biasing means arranged with effective pressure between the locking element and the bottom of the longitudinal slot so that the curved outer surface of the locking element is pressed outwards against the undercut locking surface . 2. Kombination nach Anspruch 1, bei welcher das Sperrmittel mehrere einzelne Sperrelemente umfaßt, die im wesentlichen in gleichem Abstand längs des Längsschlitzes angeordnet sind.2. A combination according to claim 1, wherein the locking means comprises a plurality of individual locking elements arranged substantially equally spaced along the longitudinal slot. Sr.hw/M:Sr.hw/M: U &ogr;&ogr; U / obU γγ U / ob
3. Kombination nach Anspruch 2, bei welcher das Sperrelement im wesentlichen zylindrisch geformt ist.3. A combination according to claim 2, wherein the locking element is substantially cylindrically shaped. 4. Kombination nach Anspruch 1, bei welcher die hinterschnittene Sperrfläche im wesentlichen eben ist und die Krümmung der Außenfläche des Sperrmittels einen solchen Radius hat, daß im wesentlichen ein Linienkontakt zwischen den Sperrmitteln und der Sperrfläche geschaffen wird.4. A combination according to claim 1, wherein the undercut blocking surface is substantially planar and the curvature of the outer surface of the blocking means has a radius such that substantially line contact is created between the blocking means and the blocking surface. 5. Kombination nach Anspruch 2, bei welcher in dem Längsschlitz Abstandsmittel angeordnet sind, die die Sperrelemente und die Federvorspannungsmittel aufnehmen, so daß die Sperrmittel in einer vorbestimmten Position entlang der Länge des Längsschlitzes gehalten werden.5. A combination according to claim 2, wherein spacer means are arranged in the longitudinal slot for receiving the locking elements and the spring biasing means so that the locking means are held in a predetermined position along the length of the longitudinal slot. 6. Kombination nach Anspruch 2, bei welcher die Federvorspannungsmittel in Befestigungsöffnungen angeordnet sind, die längs der Länge des Längsschlitzes gebildet sind.6. A combination according to claim 2, wherein the spring biasing means are disposed in mounting openings formed along the length of the longitudinal slot. 7. Kombination nach Anspruch 2, bei welcher die Federvorspannungsmittel auf Abstandsbolzen angebracht sind, die längs der Länge des Längsschlitzes angeordnet sind.7. A combination according to claim 2, wherein the spring biasing means are mounted on standoffs arranged along the length of the longitudinal slot. 8. Kombination nach Anspruch 1, bei welcher der Längsschlitz zwei hinterschnittene Sperrflächen aufweist und das Sperrmittel eine gekrümmte Außenfläche aufweist, die beide hinterschnittenen Flächen gleichzeitig berührt.8. A combination according to claim 1, wherein the longitudinal slot has two undercut locking surfaces and the locking means has a curved outer surface which contacts both undercut surfaces simultaneously. 9. Kombination nach Anspruch 3, bei welcher die Sperrelemente mit einer Öffnung zur Aufnahme eines Endes der Federvorspannungsmittel versehen sind.9. A combination according to claim 3, wherein the locking elements are provided with an opening for receiving an end of the spring biasing means. 10. Kombination nach Anspruch 1 mit einer Druckplatte, die an dem Druckzylinder mit einander berührenden Enden und eingeklemmt zwischen der hinterschnittenen Sperrfläche des Sperrmittels befestigt ist.10. A combination according to claim 1, comprising a pressure plate attached to the pressure cylinder with ends touching each other and clamped between the undercut locking surface of the locking means. 11. Kombination nach Anspruch 1, bei welcher der Längsschlitz zwei hinterschnittene Flächen bildet und ein Füllmittel innerhalb des Schlitzes angrenzend an eine der hinterschnittenen Flächen so angebracht ist, daß es das Sperrmittel berührt und von der anderen hinterschnittenen Fläche isoliert.11. A combination according to claim 1, wherein the longitudinal slot forms two undercut surfaces and a filler means is mounted within the slot adjacent one of the undercut surfaces so as to contact and isolate the blocking means from the other undercut surface.
