In Fig. 1 ist eine Druckmaschine mit einem Druckzylinder 1 mit drei Druckflächen 2.1; 2.2; 2.3 und drei Greiferreihen 3.1; 3.2; 3.3 dargestellt.
Der Druckzylinder 1 wirkt mit zwei Offsetzylindern 4 zusammen. Jeder Offsetzylinder 4 ist mit zwei Wirkflächen 9.1; 9.2 ausgestattet.
Damit besitzt der Druckzylinder 1 bezogen auf den Offsetzylinder 4 mit i Wirkflächen i+1 Druckflächen. Der Offsetzylinder 4 läuft mit der Drehzahl nO = 1 und der Druckzylinder 1 mit der Drehzahl nD = 2/3 um.
Dem Druckzylinder 1 ist eine Bogenzuführung 5, beispielsweise ein Vorgreifer, zugeordnet.
Der Bogenübernahmepunkt Bogenzuführung/Druckzylinder ist mit dem Bezugszeichen 6 gekennzeichnet.
Dem Druckzylinder 1 ist weiterhin eine Bogenabführung 7 zugeordnet. Der Bogenübergabepunkt Druckzylinder/Bogenabführung ist mit dem Bezugszeichen 8 gekennzeichnet.In Fig. 1 is a printing press with a printing cylinder 1 with three printing surfaces 2.1; 2.2; 2.3 and three gripper rows 3.1; 3.2; 3.3 shown.
The pressure cylinder 1 interacts with two offset cylinders 4. Each offset cylinder 4 is provided with two active surfaces 9.1; 9.2 equipped.
Thus, the pressure cylinder 1 has i effective areas i + 1 pressure areas in relation to the offset cylinder 4. The offset cylinder 4 rotates at the speed n O = 1 and the impression cylinder 1 at the speed n D = 2/3.
A sheet feeder 5, for example a pre-gripper, is assigned to the printing cylinder 1.
The sheet transfer point sheet feed / impression cylinder is identified with the reference number 6.
A sheet discharge 7 is also assigned to the impression cylinder 1. The sheet transfer point printing cylinder / sheet discharge is identified by the reference number 8.

In den Figuren 2 bis 7 ist der Druckzylinder 1 in den einzelnen Bogenübernahme- und Bogenübergabephasen dargestellt.
Jede Greiferreihe 3.1; 3.2; 3.3 ist jeweils mit einem mit einer Rolle ausgestatteten Rollenhebel 10.1; 10.2; 10.3 verbunden. Die Rollen der Rollenhebel stehen in Wirkverbindung mit einer Greiferbetätigungskurve 11. Die Greiferbetätigungskurve 11 läuft mit der Drehzahl des Offsetzylinders 4 um, d.h. wenn die Drehzahl der Greiferbetätigungskurve 11 1 gesetzt wird (nK = nO = 1) beträgt die Drehzahl des Druckzylinder 2/3 (nD = 2/3).
Die Greiferbetätigungskurve 11 ist zu diesem Zweck drehbar auf der Achse des Druckzylinders 1 gelagert und über ein nicht dargestelltes, fest mit der Greiferbetätigungskurve 11 verbundenes Zahnrad, welches in Wirkverbindung mit einem fest mit dem Offsetzylinder 4 verbundenem Zahnrad steht, versehen.
Befindet sich die Rolle eines Rollenhebels 10 auf dem hohen Hub 12 der Greiferbetätigungskurve 11, d.h. auf dem Kreisbogen, sind die dem jeweiligen Rollenhebel 10 zugeordnete Greifer der Greiferreihe 3 geschlossen. Befindet sich die Rolle eines Rollenhebels 10 auf dem niedrigen Hub 13 sind die dem jeweiligen Rollenhebel 10 zugeordneten Greifer der Greiferreihe 3 geöffnet. Der Greiferöffnungspunkt ist dabei mit dem Bezugszeichen 14 und der Greiferschließpunkt mit dem Bezugszeichen 15 gekennzeichnet. Der Kurvenwinkel α zwischen Greiferöffnungs- und -schließpunkt ist halb so groß wie der Betrag des Gestellwinkels β zwischen Bogenübernahme- und -übergabepunkt 6; 8.In the figures 2 to 7, the impression cylinder 1 is shown in the individual sheet transfer and sheet transfer phases.
Each gripper row 3.1; 3.2; 3.3 is each equipped with a roller lever 10.1; 10.2; 10.3 connected. The rollers of the roller levers are operatively connected to a gripper actuation curve 11. The gripper actuation curve 11 rotates at the speed of the release cylinder 4, ie if the speed of the gripper actuation curve 11 is set (n K = n O = 1), the speed of the pressure cylinder is 2 / 3 (n D = 2/3).
For this purpose, the gripper actuation curve 11 is rotatably mounted on the axis of the pressure cylinder 1 and is provided via a gearwheel, not shown, which is fixedly connected to the gripper actuation curve 11 and is operatively connected to a gearwheel which is firmly connected to the offset cylinder 4.
If the role of a roller lever 10 is on the high stroke 12 of the gripper actuation curve 11, ie on the circular arc, the grippers of the gripper row 3 assigned to the respective roller lever 10 are closed. If the roller of a roller lever 10 is on the low stroke 13, the grippers of the gripper row 3 assigned to the respective roller lever 10 are opened. The gripper opening point is identified with the reference number 14 and the gripper closing point with the reference number 15. The curve angle α between the opening and closing point of the gripper is half as large as the amount of the frame angle β between the takeover and transfer point 6; 8th.

The The beginning of the previously fed third sheet 18 has the sheet transfer point 8 happened and was handed over to the bow outlet 7. The role of the third gripper row 3.3 is on the low stroke 13 and the grippers of the third row of grippers 3.3 are opened. The grippers of the second row of grippers 3.2 remain, since the role of the roller lever 3.2 on the high stroke 12 of the Gripper actuation curve 11 is closed and there will be no Sheet taken from sheet feeder 5.

In Fig. 4 ist die dritte Phase des Bewegungsablaufes, der dem Bewegungsablauf der ersten Phase entspricht, dargestellt.

The third gripper row 3.3 is at the sheet transfer point 6 fourth sheet 19 passed because the role of the third roller lever 10.3 runs from low stroke 13 to high stroke 12 and the first Sheet 16 passes sheet transfer point 8 without gripper row opening, since the role of the first roller lever 10.1 on the high Hub 12 is running.

In Fig. 5 ist die vierte Phase des Bewegungsablaufes dargestellt. Die erste Greiferreihe 3.1 mit dem ersten Bogen 16 passiert den Bogenübernahmepunkt 6 ohne Greiferöffnung und der zweite Bogen 17 wird von den geöffneten Greifern der zweiten Greiferreihe 3.2 an die Bogenabführung 7 übergeben.5 shows the fourth phase of the movement sequence. The first gripper row 3.1 with the first sheet 16 passes through Sheet transfer point 6 without gripper opening and the second sheet 17 is from the open grippers of the second gripper row 3.2 hand over the sheet discharge 7.

In Fig. 6 ist die fünfte Phase des Bewegungsablaufes dargestellt. Der vierte Bogen 19 passiert den Bogenübergabepunkt 8 ohne Greiferöffnung und ein fünfter Bogen 20 wird an die geöffneten Greifer der zweiten Greiferreihe 3.2 übergeben.6 shows the fifth phase of the movement sequence. The fourth sheet 19 passes the sheet transfer point 8 without the gripper opening and a fifth sheet 20 is attached to the opened grippers the second gripper row 3.2.

In Fig. 7 ist die sechste Phase des Bewegungsablaufes dargestellt. In dieser sechsten Phase wird der in der ersten Phase dem Druckzylinder 1 zugeführte erste Bogen 16 der Bogenabführung 7 übergeben. 7 shows the sixth phase of the movement sequence. In this sixth phase, the one in the first phase becomes the impression cylinder 1 supplied first sheet 16 to the sheet discharge 7.
