Abstract

The cylinder has a channel projecting into the inside so that the ends of the type forme can be guided through the channel edges. At least one of the channel edges (13, 14) is curved to produce constant tension forces over the width of the type forme. The curvature increases in the centre area of the type forme and decreases in the side areas. Rollers can be provided along the curved edge to reduce friction.

Description

Die Erfindung betrifft einen Zylinder zur Aufnahme einer Druckform, insbesondere zur Aufnahme einer Druckfolie für den Offsetdruck.The invention relates to a cylinder for receiving a printing form, in particular for Inclusion of a printing film for offset printing.

Bekannte Druckformzylinder weisen im Inneren Systeme zum Auf- und Abwickeln von Druckfolie von Spulen auf. Ausgehend von der Abwickelspule ist die Folie durch einen schlitzförmigen Kanal nach außen geführt. Die Folie umschlingt die Mantelfläche des Zylinders und führt durch den gleichen Kanal oder einen weiteren Kanal ins Innere auf die Aufwickelspule zurück. Hierbei ist man bemüht, die Folie gleichmäßig auf dem Zylinder aufzuspannen, wozu hohe Spannkräfte zur Wirkung kommen, um die Reibung zwischen der Folienunterseite und der Mantelfläche zu überwinden (DE 27 56 388, DE 42 24 332 A1, DE 43 29 125 C1).Known printing form cylinders have systems for winding and unwinding inside Printing film from spools. Starting from the supply reel, the film is through a slot-shaped channel led to the outside. The film wraps around the outer surface of the Cylinder and leads through the same channel or another channel to the inside Take-up spool back. One tries to ensure that the film is evenly on the cylinder to stretch, which high clamping forces come into effect to reduce the friction between to overcome the underside of the film and the outer surface (DE 27 56 388, DE 42 24 332 A1, DE 43 29 125 C1).

Die bekannten Lösungen haben den Nachteil, dass trotz hoher Spannkräfte die Folie beweglich auf der Mantelfläche des Druckformzylinders sitzt. Dies führt beim Drucken zum Verschleiß der Folie und zu Druckfehlern.The known solutions have the disadvantage that despite high clamping forces, the film sits movably on the lateral surface of the printing form cylinder. This leads to printing for wear of the film and printing errors.

Aufgabe der Erfindung ist es, einen Zylinder zur Aufnahme einer Druckform zu entwickeln, der mit geringem Aufwand ein gleichmäßiges und bewegungsfreies Aufspannen einer Druckform ermöglicht.The object of the invention is to provide a cylinder for receiving a printing form develop that with little effort a smooth and motion-free A printing form can be clamped.

Die Lösung der Aufgabe gelingt mit einem Zylinder, der mit den Merkmalen des Anspruchs 1 ausgestattet ist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The problem is solved with a cylinder with the characteristics of Claim 1 is equipped. Advantageous configurations result from the Dependent claims.

Durch die gewölbte Ausführung mindestens einer der Kanalkanten eines Zylinders wird es möglich, eine Druckform, insbesondere eine Druckfolie, so auf der Mantelfläche aufzuspannen, dass in der Druckform über deren Breite im Wesentlichen eine gleichmäßige Zugspannung vorliegt.The arched design of at least one of the channel edges of a cylinder makes it possible, a printing form, in particular a printing film, so on the outer surface to stretch that in the printing form across its width essentially one uniform tension is present.

Die Erfindung soll anhand eines Ausführungsbeispiels noch näher erläutert werden, es zeigen:

Figur 1:
die Spannungsverteilung in einer Druckfolie 1 bei einem Zylinder mit gradlinigen Kanalkanten 2, 3,
Figur 2, 3:
einen Zylinder mit balligen Kanalkanten in zwei Ansichten.
The invention will be explained in more detail with the aid of an exemplary embodiment, in which:
Figure 1:
the stress distribution in a printing film 1 for a cylinder with straight channel edges 2, 3,
Figure 2, 3:
a cylinder with crowned channel edges in two views.

In Figur 1 ist ein Schema der Spannungsverteilung in einer Druckfolie 1 bei einem Druckformzylinder mit geradlinigen Kanalkanten 2, 3 dargestellt. Zwischen den Kanalkanten 2, 3 liegt in einer Ebene abgewickelt der auf der Mantelfläche aufliegende Bereich von Druckfolie 1 mit der Länge l und der Breite b. Die Druckfolie 1 ist zwischen einer Abwickelrolle 4 und einer Aufwickelrolle 5 über die Kanalkanten 2, 3 gespannt. Hierzu kann die Aufwickelrolle 5 mit einem Motor und die Abwickelrolle 4 mit einer Bremsvorrichtung gekoppelt sein. Die Figur 1 zeigt weiterhin die Spannungsverteilung in der Druckfolie 1 entlang der Breite b. Die Spannungsvektoren 7 zeigen in Umfangsrichtung des Zylinders. In der Nähe der Ränder 8, 9 der Druckfolie sind die Spannungsvektoren 7 betragsmäßig größer als in der Umgebung der Mittellinie 10 der Druckfolie 1. Diese ungleichmäßige Spannungsverteilung hat zur Folge, dass die Druckfolie 1 in der Umgebung der Mittellinie 10 weniger fest auf der Mantelfläche des Zylinders haftet als in der Nähe der Ränder 8, 9. Im Zusammenwirken mit einem weiteren Zylinder kann die Druckfolie 1 auf der Mantelfläche rutschen, was zu Registerfehlern beim Drucken führen kann. Der Druckformzylinder darf in radialer Richtung keine Formabweichungen aufweisen, sodass in radialer Richtung kein Ausgleich der ungleichmäßigen Spannungsverteilung möglich ist.FIG. 1 shows a diagram of the stress distribution in a printing film 1 in the case of a printing form cylinder with straight channel edges 2, 3. Between the channel edges 2, 3, the area of printing film 1 with the length l and the width b lying on the lateral surface lies unwound in one plane . The printing film 1 is stretched between an unwinding roll 4 and a winding roll 5 over the channel edges 2, 3. For this purpose, the winding roller 5 can be coupled to a motor and the unwinding roller 4 can be coupled to a braking device. FIG. 1 also shows the stress distribution in the printing film 1 along the width b . The voltage vectors 7 point in the circumferential direction of the cylinder. In the vicinity of the edges 8, 9 of the printing film, the magnitude of the stress vectors 7 is greater than in the vicinity of the center line 10 of the printing film 1. This uneven distribution of stress has the result that the printing film 1 is less tight on the circumferential surface of the device in the vicinity of the center line 10 Cylinder adheres as near the edges 8, 9. In cooperation with another cylinder, the printing film 1 can slip on the outer surface, which can lead to register errors during printing. The printing form cylinder must not have any shape deviations in the radial direction, so that it is not possible to compensate for the uneven stress distribution in the radial direction.

Ein Ausgleich für die unterschiedlichen Spannungen wird durch ballige Kanalkanten erreicht, was in den Figuren 2 und 3 näher dargestellt ist. Figur 2 zeigt einen Querschnitt durch einen Zylinder 11 mit einem Kanal 12, der Kanalkanten 13 und 14 aufweist. Innerhalb des Zylinders 11 befindet sich eine Vorratsspule 15 für Druckfolie 16. Die bahnförmige Druckfolie 16 ist ausgehend von der Vorratsspule 15 durch den Kanal 12 über die Kanalkante 14 geführt und umschlingt die Mantelfläche 17 des Zylinders 11. Das andere Ende der Druckfolie 16 führt über die Kanalkante 15 und den Kanal 12 ins Innere des Zylinders 11 auf eine Aufwickelspule 18.The spherical channel edges compensate for the different tensions achieved what is shown in more detail in Figures 2 and 3. Figure 2 shows a cross section through a cylinder 11 with a channel 12 having channel edges 13 and 14. Within the cylinder 11 there is a supply spool 15 for printing film 16. Die web-shaped printing film 16 is starting from the supply spool 15 through the channel 12 the channel edge 14 out and wraps around the lateral surface 17 of the cylinder 11. Das the other end of the printing film 16 leads into the interior via the channel edge 15 and the channel 12 of the cylinder 11 on a take-up spool 18.

Mit Blick in Richtung A zeigt Figur 3 die ballige bzw. gewölbte Ausführung der Kanalkanten 13, 14. Die Wölbungen der Kanalkanten 13, 14 sind so ausgeführt, dass sie im Bereich der Mittellinie 19 der symmetrisch auf die Mantelfläche 17 des Zylinders 11 gelegten Druckfolie 16 vorstehen. Der Kanal 12 ist in diesem Bereich verengt. In Richtung der Ränder 20, 21 der Druckfolie 16 sind die Kanalkanten 13, 14 zurückgenommen, sodass der Kanal 12 weiter als in der Mitte ist. Das Krümmungsmaß für die Kanalkanten 13, 14 ergibt sich aus den nötigen Korrekturwerten für eine gleichmäßige Spannungsverteilung. Die gleichmäßige Spannungsverteilung ergibt sich dadurch, dass bei ballig ausgeführten Kanalkanten 13, 14 in der Umgebung der Mittellinie 19 die Zugkräfte auf die Druckfolie 16 korrigierend gegenüber den Randbereichen erhöht wird. Die Zugkräfte können in herkömmlicher Weise mittels eines Aufwickelantriebes erzeugt werden, der mit der Aufwickelspule 18 gekoppelt ist. Wie oben bereits beschrieben, kann die Vorratsrolle beim Spannen mittels des Aufwickelantriebes mit einer Bremsvorrichtung gekoppelt sein oder blockiert werden.With a view towards A, Figure 3 shows the crowned or curved version of the Channel edges 13, 14. The curvatures of the channel edges 13, 14 are designed so that they are in the Area of the center line 19 which is symmetrical on the lateral surface 17 of the cylinder 11 projecting printing film 16 protrude. The channel 12 is narrowed in this area. In the direction of the edges 20, 21 of the printing film 16, the channel edges 13, 14 are withdrawn, so that the channel 12 is wider than in the middle. The degree of curvature for the channel edges 13, 14 results from the necessary correction values for an even stress distribution. The even distribution of stress results from the fact that with crowned Channel edges 13, 14 in the vicinity of the center line 19, the tensile forces on the printing film 16 is corrected relative to the edge areas. The tensile forces can be in be generated in a conventional manner by means of a winding drive, which with the Take-up spool 18 is coupled. As already described above, the supply role can be at Tensioning can be coupled to a braking device by means of the winding drive or be blocked.

Der positive Effekt des Spannungsausgleiches tritt bereits ein, wenn nur eine der Kanalkanten 13, 14 ballig ausgeführt ist. Zur Verbesserung des Spannungsvorganges können Maßnahmen getroffen werden, die die Reibung der Druckfolie 16 auf der Mantelfläche 17 und über die Kanalkanten 13, 14 verringert. Zum Beispiel können die Kanalkanten 13, 14 abgerundet und mit geringer Reibung ausgebildet sein. Des Weiteren wären Rollenelemente einsetzbar, über die die Druckfolie 16 an den Kanalkanten 13, 14 geführt ist, wobei die Rollenelemente die konvexe Form der Kanalkanten 13, 14 annehmen. Bei Zylindern, die mehrere Kanäle 12 aufweisen, können die Kanalkanten 13, 14 einheitlich, wie oben beschrieben, ballig ausgeführt werden. The positive effect of voltage equalization already occurs if only one of the Channel edges 13, 14 is crowned. To improve the tensioning process measures can be taken to reduce the friction of the printing film 16 on the Shell surface 17 and reduced over the channel edges 13, 14. For example, the Channel edges 13, 14 are rounded and designed with low friction. Furthermore it would be possible to use roller elements via which the printing film 16 on the channel edges 13, 14 is guided, the roller elements having the convex shape of the channel edges 13, 14 accept. In the case of cylinders which have a plurality of channels 12, the channel edges 13, 14 uniformly, as described above, crowned.
