In einen Kanal 1 eines Plattenzylinders 2 ist eine Spanneinrichtung 3 für das nachlaufende Plattenende 4 vorgesehen, mit der die Druckplatte 5 auf der Mantelfläche des Plattenzylinders gespannt werden kann. Auf einer Welle 6, die in Längsrichtung des Plattenzylinders im Kanal 1 vorgesehen ist, sind Spannelemente 7 befestigt. An den Spannelementen 7 sind über Bolzen 8 Klemmelemente 9 gelagert, mit denen ein abgewinkeltes Plattenende 4 in Verbindung mit dem Spannelement 7 festgeklemmt werden kann. Nach dem Klemmen erfolgt sodann das Spannen der Druckplatte 5. Zum Entspannen und Lösen des Plattenendes sind Pneumatikeinheiten 10 vorgesehen, die auf das Spannelement 7 einwirken können (Fig. 2), so daß das Spannelement 7 entgegen dem Uhrzeigersinn verdreht wird und sich Ansätze 11 an den Klemmelementen 9 an einem Vorsprung 12 am Plattenzylinder abstützen. Hierdurch öffnet sich gleichzeitig das Klemmelement 9 soweit, daß die Druckplatte 5 entnommen und eine neue Druckplatte auf einfache Weise einzulegen ist. In a channel 1 of a plate cylinder 2 is one Clamping device 3 for the trailing plate end 4 provided with which the pressure plate 5 on the lateral surface of the plate cylinder can be clamped. On a wave 6, in the longitudinal direction of the plate cylinder in channel 1 is provided, clamping elements 7 are attached. To the Clamping elements 7 are mounted on bolts 8, clamping elements 9, with which an angled plate end 4 in connection with the clamping element 7 can be clamped. After clamping the pressure plate 5 is then tensioned to relax and releasing the plate end are pneumatic units 10 provided that can act on the clamping element 7 (Fig. 2), so that the clamping element 7 against the Is rotated clockwise and approaches 11 to the Clamping elements 9 on a projection 12 on the plate cylinder support. This opens the at the same time Clamping element 9 so far that the pressure plate 5 is removed and a new printing plate is easy to insert.

Gemäß der Erfindung sind an den Klemmelementen 9 gefederte Obergreifer 13 befestigt, die die Klemmung eines abgewinkelten Plattenendes 4 unterstützen und ein nicht abgewinkeltes Plattenende auf dem Spannelement 7 festklemmen.According to the invention, 9 are sprung on the clamping elements Upper gripper 13 attached, which is the clamping of a support angled plate end 4 and a not Clamp the angled plate end onto the clamping element 7.

Gemäß den Figuren 1 bis 3 sind die Obergreifer 13 zum Beispiel aus Federstahl ausgeführt und an ihrem dem Greifbereich gegenüberliegenden Ende an dem Klemmelement 9 befestigt.According to Figures 1 to 3, the top gripper 13 for Example made of spring steel and on their Gripping area opposite end on the clamping element 9 attached.

Gemäß Fig. 4 können die Obergreifer 13 zweiteilig ausgebildet sein mit einem starren Greiferteil 14 und einem Federteil 15. Das Federteil 15 ist hierbei ebenfalls über Schrauben 16 an dem Klemmelement 9 befestigt. Zusätzlich stützt sich das starre Greiferteil 14 auf einer Anlage 17 am Klemmelement 9 ab, so daß hohe Klemmkräfte mit dem starren Greiferteil 14 auf das nicht abgewinkelte Druckplattenende 4 übertragen werden können.4, the top grippers 13 can be formed in two parts be with a rigid gripper part 14 and a spring part 15. The spring part 15 is also here via screws 16 the clamping element 9 attached. This is also supported rigid gripper part 14 on a system 17 on the clamping element 9 from so that high clamping forces with the rigid gripper part 14th transferred to the non-angled printing plate end 4 can be.

Wie in den Figuren 1, 2 und 5 gezeigt sind Spannfedern 18 zwischen Plattenzylinder 2 und den Klemmelementen 9 über die Länge des Plattenzylinders 2 angeordnet, deren Spannkraft zwischen die Welle 6 zur Aufnahme der Spannelemente 7 und die Bolzen 8 zur Aufnahme der Klemmelemente 9 gerichtet ist. Die Spannkraft der Spannfedern 18 bewirkt somit ein Schließen des Klemmelements 9 und danach ein Spannen des Spannelements 7. Hierbei wird das Klemmelement 9 entgegen dem Uhrzeigersinn verdreht und das Spannelement 7 im Uhrzeigersinn. Es genügt somit eine Reihe Spannfedern 18 um beide Funktionen auszuführen.As shown in FIGS. 1, 2 and 5, tension springs 18 between plate cylinder 2 and the clamping elements 9 via the Length of the plate cylinder 2 arranged, the clamping force between the shaft 6 for receiving the clamping elements 7 and the Bolt 8 for receiving the clamping elements 9 is directed. The Clamping force of the tension springs 18 thus causes the closing of the Clamping element 9 and then tensioning the clamping element 7. Here, the clamping element 9 is counterclockwise rotated and the clamping element 7 clockwise. It is sufficient thus a series of tension springs 18 around both functions to execute.

Zwischen den einzelnen Spannfedern 18 in Längsrichtung des Plattenzylinders 2 gesehen sind Spannschrauben 19 vorgesehen, die gemäß Fig. 3 und 4 sowohl auf den einteiligen gefederten Obergreifer 13 (Fig. 3) als auch auf den zweiteiligen Obergreifer 13 (Fig. 4) anstellbar sind. Das Anstellen geschieht zur Erhöhung der Spannkraft der Spanneinrichtung 3, so daß bei eingespannter Druckplatte unabhängig ob abgekantete oder nicht abgekantete Druckplatte ein Strecken in Umfangsrichtung durchgeführt werden kann. Selbstverständlich läßt sich auch ein Dehnen des Druckplattenendes 4 in axialer Richtung bei dieser erhöhten Spannkraft durchführen. Nach dem Strecken oder Dehnen der Druckplatte werden die Spannschrauben 19 wieder zurückgedreht, so daß die Spanneinrichtung 3 in normaler Weise betätigt werden kann. Between the individual tension springs 18 in the longitudinal direction of the Seen plate cylinder 2 clamping screws 19 are provided, 3 and 4 both on the one-piece sprung Top gripper 13 (Fig. 3) as well as the two-part Upper gripper 13 (FIG. 4) can be set. The queuing happens to increase the clamping force of the clamping device 3, so that when the printing plate is clamped in, regardless of whether beveled or not beveled pressure plate stretching can be carried out in the circumferential direction. Of course, you can also stretch the Pressure plate end 4 increased in the axial direction at this Carry out tension. After stretching or stretching the Pressure plate, the clamping screws 19 again turned back so that the tensioning device 3 in normal Way can be operated.
