In the circumferential direction of the Transfer cylinder is for receiving two in the longitudinal direction of the cylinder printing blankets arranged side by side a single one, either lengthways continuous slot or one slot divided lengthways and offset by 180 ° arranged. The printing blanket, for example, has two layers as one on a carrier plate attached rubber blanket executed.

In der DE 34 41 175 C2 werden zum Zweck der Entspannung des Gummituches Ausnehmungen in der Zylinderoberfläche des Übertragungszylinders vorgeschlagen. Zwischen Zylinder und Gummituch kann auch zu diesem Zweck eine Unterlage angeordnet sein, die nicht über die gesamte Länge des Gummituches in Umfangsrichtung weist und eine Unterbrechung aufweist. Zur Aufnahme der unterbrochenen Unterlage ist neben dem Spannkanal für das Gummituch ein Einsteckschlitz auf dem Umfang des Zylinders vorgesehen. Die in Längsrichtung des Übertragungszylinders angeordneten Ausnehmungen und der das Gummituch aufnehmende Kanal werden so angeordnet, dass sie im Berührungsbereich jeweils mit dem Kanal des Plattenzylinders zusammen wirken.DE 34 41 175 C2 are for the purpose of relaxing the rubber blanket Recesses in the cylinder surface of the transfer cylinder proposed. For this purpose, a pad can be placed between the cylinder and the rubber blanket be arranged, not over the entire length of the blanket in the circumferential direction points and has an interruption. To hold the interrupted pad in addition to the tensioning channel for the rubber blanket, an insertion slot on the circumference of the Cylinder provided. The arranged in the longitudinal direction of the transfer cylinder Recesses and the channel receiving the rubber blanket are arranged so that they are together with the channel of the plate cylinder in the contact area Act.

B. um 180°, Kanäle 14; 16 auf, wobei die nebeneinander angeordneten Drucktücher ebenfalls zueinander versetzt angeordnet sind (nicht explizit dargestellt, zweiter Kanal 16 wäre in Fig. 1 verdeckt und nicht sichtbar).The transfer cylinder not used in the version with two printing blankets 09 02 in FIG. 1 has two in the axial direction next to one another, but offset from one another, z. B. by 180 °, channels 14; 16, with the printing blankets arranged side by side are also arranged offset from one another (not explicitly shown, second channel 16 would be hidden in Fig. 1 and not visible).

Im Gegensatz zur in Fig. 1 mit dem Formzylinder 03; 08 zusammen wirkend dargestellten, nicht beanspruchten doppelt breiten Ausführungsform des Übertragungszylinders 02 ist dieser erfindungsgemäß dreifach breit ausgeführt. Der mit den zwei Kanäle 12, 13 aufweisenden Formzylindem 03; 08 zusammen wirkende Übertragungszylinder 02; 07 aus dem ersten Beispiel (Fig. 1) ist mit mehreren in Längsrichtung nebeneinander angeordneten Drucktüchern 09 belegt. In Fig. 2 kann in diesem Fall z. B. auch ein Formzylinder 03 doppelten Umfangs aus Fig. 1 und dessen Beschreibung an die Stelle des in Fig. 2 dargestellten Formzylinders 03; 08 treten.In contrast to the forme cylinder 03; 08 shown interacting, is not claimed double-wide embodiment of the transfer cylinder 02 this is designed according to the invention three times as wide. The one with the two channels 12, 13 having forme cylinders 03; 08 interacting transfer cylinders 02; 07 from the first example (Fig. 1) with several in the longitudinal direction side by side arranged printing blankets 09 occupied. In this case, in FIG. B. also a Forme cylinder 03 of double circumference from Fig. 1 and its description in place of the forme cylinder 03 shown in FIG. 2; 08 kick.

Mit dem gemäß Fig. 1 dargestellten, für die doppelbreite Ausführung nicht beanspruchten Formzylinder 03, 08 kann auch ein Übertragungszylinder doppelten Umfangs zusammen wirken, welcher zwei in axialer Richtung versetzt nebeneinander und gleichzeitig in Umfangsrichtung hintereinander angeordnete Kanäle aufweist.With the forme cylinder shown in FIG. 1, not claimed for the double-width version 03, 08 a double-dimensioned transfer cylinder can also work together, which two are offset in the axial direction next to each other and simultaneously in Has channels arranged one behind the other in the circumferential direction.

Die Beispiele zeigen zwar jeweils zwei eine Druckeinheit bildende, doppelt breite Zylinderpaare 01; 06, wobei die beiden Übertragungszylinder 02; 07 über den Bedruckstoff 04 zusammen wirken. Die Zylinderpaare 01; 06 sind erfindungsgemäß jedoch dreifach breit ausgeführt. Die Lehre aus den Beispielen der Figuren ist entsprechend anzuwenden. Für alle Ausführungsbeispiele kann der zusammen wirkende Formzylinder 03; 08 mehreren in Längsrichtung nebeneinander und gleichzeitig mit mehreren in Umfangsrichtung hintereinander angeordneten Druckformen belegt sein. Auch die in Fig. 1 dargestellte Ausführungsform für den mit dem Übertragungszylinder 02; 07 der Fig. 2 zusammen wirkenden Formzylinder 03; 08 ist anzuwenden.The examples each show two double-width units forming a printing unit Cylinder pairs 01; 06, the two transfer cylinders 02; 07 over the Print substrate 04 work together. The cylinder pairs 01; 06 are according to the invention but three times wide. The lesson from the examples of Figures must be used accordingly. For all embodiments, the interacting forme cylinders 03; 08 several alongside each other and simultaneously with several in Circumferential printing form arranged one behind the other. Also in Fig. 1 illustrated embodiment for the with the transfer cylinder 02; 07 the Fig. 2 cooperating forme cylinder 03; 08 is to be applied.

Gemäß Fig. 2 sind die beiden Drucktücher 09 des nicht beanspruchten Druckwerkes in Umfangsrichtung um 180° versetzt zueinander angeordnet, wobei dann jeweils ein Teil des Kanals 14 und ein Teil des Kanals 16 überdeckt ist. In Abwandlung der Fig. 2 erfolgt erfindungsgemäß die Anordnung von drei nebeneinander angeordneten Drucktüchern 09, insbesondere bei sehr langen Zylindern, in analoger Weise alternierend.2, the two printing blankets 09 of the printing unit not claimed are in Circumferential direction offset by 180 ° to each other, with one part of the channel 14 and part of the channel 16 is covered. Modified in FIG. 2 according to the invention the arrangement of three arranged side by side Printing blankets 09, in particular in the case of very long cylinders, alternating in an analogous manner.

Sowohl für die Übertragungszylinder 02; 07 als auch für die Formzylinder 03; 08 ist jeweils die in Umfangsrichtung symmetrische Anordnung der Kanäle 12; 13 bzw. 14; 16 mit nahezu gleichen Zwischenwinkeln vorteilhaft, z. B. bei zwei Kanälen 12; 13 bzw. 14; 16 um jeweils 180°, bei dreien alternierend um 180° versetzt. Bei mehr als jeweils zwei Kanälen 12; 13 bzw. 14; 16 können mehrere in Längsrichtung nebeneinander angeordnete Druckplatten 11 oder Drucktücher 09 auch in Umfangsrichtung zueinander versetzt sein.Both for the transfer cylinder 02; 07 as well as for the forme cylinders 03; 08 is each the circumferentially symmetrical arrangement of the channels 12; 13 or 14; 16 with almost the same intermediate angles advantageous, z. B. with two channels 12; 13 or 14; 16 by 180 ° each, with three alternately offset by 180 °. With more as two channels 12; 13 or 14; 16 can several in the longitudinal direction juxtaposed printing plates 11 or printing blankets 09 also in Be circumferential to each other.

Das Verhältnis des Umfangs der Übertragungszylinder 02; 07 zu dem der Formzylinder 03; 08 ist vorteilhaft ganzzahlig, insbesondere für den Fall eines Formzylinders 03; 08 mit in Umfangsrichtung hintereinander angeordneten Kanälen 12; 13 bei doppelt großem Umfang gleich 1.The ratio of the circumference of the transfer cylinder 02; 07 to that of the forme cylinder 03; 08 is advantageously an integer, in particular in the case of a forme cylinder 03; 08 with in the circumferential direction one behind the other channels 12; 13 for twice the size Scope equal to 1.

Die in Fig. 2 dargestellten beiden Zylinderpaare 01 und 06 müssen nicht in der selben Weise mit der gleichen Kanalanzahl und -geometrie ausgerüstet, bzw. mit dem gleichen Muster für die Aufzüge 09; 11 belegt sein. Vorteilhaft ist jedoch eine Abstimmung der Phasen nicht druckender Bereiche der zusammen wirkenden Übertragungszylinder 02; 07 so, dass möglichst nicht druckende Bereiche, insbesondere Bereiche der verdeckten bzw. nicht verdeckten Kanäle zusammenwirken.The two pairs of cylinders 01 and 06 shown in FIG. 2 do not have to be in the same Equipped with the same number and geometry of channels, or with the same Pattern for the elevators 09; 11 be occupied. However, it is advantageous to coordinate the Phases of non-printing areas of the interacting transfer cylinders 02; 07 so that areas that are not printing, in particular areas of the hidden or uncovered channels interact.

Die in Fig. 1 und den zugehörigen Beschreibungen dargelegten Belegungen der Übertragungszylindem 02; 07 mit Drucktüchem 09 sind auch auf das jeweils andere Beispiel entsprechend anzuwenden. Gleiches gilt für die Belegung der Formzylinder 03; 08 und die Übertragung auf die anderen Beispiele im Zusammenhang mit unterschiedlichen Ausführungen des Übertragungszylinders 02; 07.The assignments of FIG. 1 and the associated descriptions Transfer cylinders 02; 07 with blankets 09 are also on top of each other Apply the example accordingly. The same applies to the assignment of the forme cylinder 03; 08 and the transfer to the other examples related different versions of the transfer cylinder 02; 07th

In den Fig. 1 und 2 sind die Kanäle 12; 13, 14, 16; 17; 18 jeweils bis zur Stirnseite des Zylinders 02; 04, 07; 08 verlaufend dargestellt. Beispielsweise aus Stabilitätsgründen, aus Gründen der Verschmutzung oder bei Verwendung von Schmitzringen kann jedoch stimseitig ein Rand ohne Kanal 12; 13; 14; 16; 17; 18 vorliegen. Die Kanäle 12; 13; 14; 16; 17; 18 verlaufen in diesem Fall nahezu über die gesamte Länge des Zylinders 02; 03, 07; 08 bzw. dessen Ballens.1 and 2, the channels 12; 13, 14, 16; 17; 18 each to the front of the Cylinder 02; 04, 07; 08 shown in progress. For example, for reasons of stability However, due to contamination or when using bearer rings on the face side an edge without channel 12; 13; 14; 16; 17; 18 are present. The channels 12; 13; 14; 16; 17; 18 run in this case almost over the entire length of the cylinder 02; 03, 07; 08 or its bale.

Die genannten Beispiele für die Anordnung von Kanälen 12; 13; 14; 16; 17; 18 und Aufzügen 09; 11 auf Übertragungszylinder 02; 07 und Formzylinder 03; 08 sowie Konfigurierungen von Druckwerken mit einem Zylinderpaar 01; 06 aus einem Übertragungszylinder 02; 07 und einem zusammen wirkenden Formzylinder 03; 08 sind für den erfindungsgemäßen Fall anzuwenden, wenn das Zylinderpaar 01; 06, nicht mit einem zweiten Übertragungszylinder 07, wie in Fig. 2 dargestellt, sondern mit einem beispielsweise als Stahlzylinder ausgeführten Gegendruckzylinder zusammen wirkt.The examples mentioned for the arrangement of channels 12; 13; 14; 16; 17; 18 and Elevators 09; 11 on transfer cylinder 02; 07 and forme cylinder 03; 08 as well Configurations of printing units with a pair of cylinders 01; 06 from one Transfer cylinder 02; 07 and a cooperating forme cylinder 03; 08 are to be used for the case according to the invention if the pair of cylinders 01; 06, not with a second transfer cylinder 07, as in FIG. 2 shown, but with a For example, counter pressure cylinders designed as steel cylinders cooperate.

Unter Aufzug 11 wird hier z. B. eine einteilige Druckplatte 11 verstanden. Der Aufzug 09 für den Übertragungszylinder 02; 07 stellt ein einteiliges Drucktuch 09 dar. Dieses einteilige Drucktuch 09 ist mehrschichtig ausgeführt, wobei für letzteres auf einer Trägerplatte 21 beispielsweise mindestens eine Schicht 22 aufgebracht und mit dieser fest verbunden ist. Die Enden 23; 24 des ein- oder mehrschichtigen Drucktuches 09 wirken mit einer im Kanal 14; 16; 17; 18 angeordneten Halteeinrichtung 26 zusammen.Under elevator 11 z. B. understood a one-piece pressure plate 11. The elevator 09 for the transfer cylinder 02; 07 represents a one-piece printing blanket 09. This one-piece printing blanket 09 is multi-layered, whereby for the latter, for example, at least one layer 22 on a carrier plate 21 applied and firmly connected to this. The ends 23; 24 of the one or multilayer printing blanket 09 act with one in channel 14; 16; 17; 18 arranged Holding device 26 together.

Insbesondere in Verbindung mit schmalen Öffnungen der Kanäle 14; 16; 17; 18 zur Mantelfläche des Übertragungszylinder 02; 07 hin ist die Ausbildung des Drucktuches 09 als mehrschichtiges Drucktuch 09 vorteilhaft, welches beim Abrollen beispielsweise des Formzylinders 03 am Übertragungszylinder 02 durch Walken seine Länge oder Breite nicht oder nur unwesentlich ändert, d. h. nahezu dimensionsfest ist. Hierzu weist die Drucktucheinheit 09, wie in Fig. 3 gezeigt, die nahezu dimensionsfeste Trägerplatte 21, beispielsweise aus Metall oder Kunststoff, auf, auf der die elastische oder weiche Schicht 22 aufgebracht ist (angedeutet in Fig. 1). Im vorliegenden Beispiel für das mehrschichtige Drucktuch 09 sind die Enden 23 und 24 des Drucktuches 09 mit den Enden der Trägerplatte 21 identisch, da die Trägerplatte 21 im mit dem Kanal 14; 16; 17; 18 zusammen wirkenden Bereich abgebogen und unbeschichtet ist.In particular in connection with narrow openings of the channels 14; 16; 17; 18 to Lateral surface of the transfer cylinder 02; 07 is the formation of the printing blanket 09 advantageous as a multilayer printing blanket 09, which, for example, when unrolling the Forme cylinder 03 on transfer cylinder 02 by flexing its length or width does not change or changes only insignificantly, d. H. is almost dimensionally stable. The Printing blanket unit 09, as shown in FIG. 3, the almost dimensionally stable carrier plate 21, for example made of metal or plastic, on which the elastic or soft layer 22 is applied (indicated in Fig. 1). In the present example for the multilayer Blanket 09 are the ends 23 and 24 of blanket 09 with the ends of the Carrier plate 21 identical, since the carrier plate 21 in the channel 14; 16; 17; 18 cooperating area is bent and uncoated.

Die Trägerplatte 21 des mehrschichtigen Drucktuches 09 kann in anderer Ausführung auch bis zu den Enden der Trägerplatte 21 beschichtet sein, wobei in diesem Fall die Enden 23 und 24 des mehrschichtigen Drucktuches 09 neben der Trägerplatte 21 auch die Schicht 21 aufweisen. Ist das Drucktuch als einfaches Gummituch 09 ausgeführt, so wirken die Enden 23; 24 des Gummituches 09 mit den Kanälen 14; 16; 17; 18 zusammen.The carrier plate 21 of the multilayer printing blanket 09 can be of a different design also be coated up to the ends of the carrier plate 21, in which case the Ends 23 and 24 of the multilayer printing blanket 09 in addition to the carrier plate 21 have the layer 21. If the printing blanket is designed as a simple blanket 09, so act the ends 23; 24 of the rubber blanket 09 with the channels 14; 16; 17; 18 together.

Auch die Kanäle 12; 13 können in vorteilhafter Ausführung Halteeinrichtungen 33 für die Druckformen 11 aufweisen.The channels 12; 13 can hold devices 33 for the advantageous embodiment Have printing forms 11.

Die Halteeinrichtung 26; 33 kann eine bekannte Vorrichtung zum kraft- oder formschlüssigen Halten und/oder Spannen eines Aufzuges 09; 11 sein, wie z. B. kraftoder formschlüssige Mechanismen, über Federkraft oder Getriebe angetriebene Klemmleisten oder Wellen, oder tangentialen Mitnehmer. The holding device 26; 33 can be a known device for power or positive locking and / or tensioning of an elevator 09; 11, such as B. Kraftoder positive mechanisms, driven by spring force or gear Terminal strips or shafts, or tangential drivers.

Eine vorteilhafte Ausführung einer Halteeinrichtung 26; 33 für einen Aufzug 09; 11, insbesondere für ein mehrschichtiges Drucktuch 09 oder eine Druckform 11, ist am Beispiel eines mehrschichtigen Drucktuches 09 in Fig. 3 anhand des Kanals 14 im Übertragungszylinder 02 stellvertretend dargestellt. Die Anordnung einer derartigen oder ähnlichen Halteeinrichtungen für die Druckformen 11 in den Kanälen 12; 13 ist nicht dargestellt.An advantageous embodiment of a holding device 26; 33 for an elevator 09; 11 in particular for a multilayer printing blanket 09 or a printing form 11, is on Example of a multi-layer printing blanket 09 in Fig. 3 using the channel 14 in Transfer cylinder 02 shown as an example. The arrangement of such or similar holding devices for the printing plates 11 in the channels 12; 13 is not shown.

Die Halteeinrichtung 26 ist im axial verlaufenden Kanal 14 des Übertragungszylinder 02 zum Halten des Drucktuches 09 angeordnet. Die Betätigung der Vorrichtung für das Spannen oder Halten des mehrteiligen Drucktuches 09 erfolgt über eine im Kanal 14 des Übertragungszylinder 02 drehbar gelagerte Welle 27, beispielsweise eine Spindel 27 mit Druckstücken 28.The holding device 26 is in the axially extending channel 14 of the transfer cylinder 02 arranged to hold the blanket 09. Operation of the device for the Tensioning or holding the multi-part printing blanket 09 takes place via a in the channel 14 of the Transfer cylinder 02 rotatably mounted shaft 27, for example a spindle 27 with Pressure pieces 28.

Der parallel zur Achse des Übertragungszylinder 02 verlaufende, zur Tangente der Mantelfläche um 30 bis 60°, insbesondere um ca. 45°, geneigte Kanal 14 weist einen Spalt 29 auf der Mantelfläche des Übertragungszylinder 02 und eine im Inneren des Übertragungszylinder 02 liegende, mit dem Spalt 29 verbundene, Bohrung 31 auf. Die Breite b29 des Spaltes 29 im Bereich der Mantelfläche in Umfangsrichtung des Übertragungszylinders (02; 03; 07; 08) ist größer als die doppelte Dicke eines der Enden 23; 24 des Drucktuches 09, was im vorliegenden Beispiel gleichbedeutend mit der doppelten Dicke der Trägerplatte 21 ist. Für die Breite b29 des Spaltes 29 gilt vorteilhafter Weise 1 mm ≤ b29 ≤ 5 mm, insbesondere b29 ≤ 3 mm. Für den Fall eines einfachen Gummituches 09 ist die Breite b29 unwesentlich größer als die doppelte Dicke des Gummituches 09, im Fall des bis zu den Enden der Trägerplatte 21 beschichteten mehrschichtigen Drucktuches 09 ist die Breite b29 unwesentlich größer als die doppelte Dicke des beschichteten Endes 23; 24 des mehrschichtigen Drucktuches 09 zu wählen.The parallel to the axis of the transfer cylinder 02, to the tangent of the The lateral surface inclined by 30 to 60 °, in particular by approximately 45 °, has a channel 14 Gap 29 on the outer surface of the transfer cylinder 02 and one inside the Transfer cylinder 02 lying, connected to the gap 29, bore 31. The Width b29 of the gap 29 in the circumferential direction of the lateral surface Transfer cylinder (02; 03; 07; 08) is larger than twice the thickness of one of the ends 23; 24 of the blanket 09, which in the present example is synonymous with the is twice the thickness of the carrier plate 21. The width b29 of the gap 29 is more advantageous Way 1 mm ≤ b29 ≤ 5 mm, especially b29 ≤ 3 mm. In the case of a simple one Rubber blanket 09, the width b29 is slightly larger than twice the thickness of the Rubber blanket 09, in the case of coated up to the ends of the carrier plate 21 multilayer printing blanket 09, the width b29 is insignificantly larger than double Thickness of coated end 23; 24 of the multilayer printing blanket 09 to choose.

In der Bohrung 31 ist die Welle 27, im Beispiel eine schwenkbare Spindel 27, angeordnet, in der die Druckstücke 28, z. B. Stempel, Kugeln oder vergleichbares, federnd und radial nach außen gerichtet angeordnet sind.The shaft 27, in the example a pivotable spindle 27, is arranged in the bore 31, in which the pressure pieces 28, z. B. stamps, balls or similar, resilient and radial are arranged facing outwards.

Zum Klemmen des Drucktuches 09 werden beide Enden 23; 24 des Drucktuches 09, im Beispiel gleichbedeutend mit den Enden der Trägerplatte 21, in den Spalt 29 geführt und die Spindel 27 mit den Druckstücken 28 so verschwenkt, dass diese nahezu senkrecht gegen das vor- und nachlaufenden Ende 23 und 24 des Drucktuches 09 bzw. der Trägerplatte 21 und eine zylinderfeste Wand 32 drückt und diese kraftschlüssig im Spalt 29 hält. Sind in Umfangsrichtung des Übertragungszylinder 02 mehrere Drucktücher 09 hintereinander angeordnet, so wirken jeweils ein vor- und ein nachlaufendes Ende 23 und 24 benachbarter Drucktücher 09 zusammen. Die Halteeinrichtung 26 kann zusätzlich einen nicht dargestellten Schieber aufweisen, der zusätzlich zu den Enden 23 und 24 in den Spalt 29 einschiebbar ist und den Spalt 29 nach außen hin abschließt. Vorteilhaft ist dieser Schieber mit der Spindel 27 verbunden, so dass er bei Verschwenken der Spindel 27 in den bzw. aus dem Spalt 29 bewegt wird. Die Breite b29 des Spaltes 29 ist bei Verwendung eines derartigen Schiebers entsprechend größer ausgebildet.To clamp the blanket 09, both ends 23; 24 of the printing blanket 09, in Example synonymous with the ends of the support plate 21, in the gap 29 and the spindle 27 is pivoted with the pressure pieces 28 so that they are almost vertical against the leading and trailing ends 23 and 24 of the blanket 09 and the Carrier plate 21 and a cylinder-fixed wall 32 presses and this non-positively in the gap 29 holds. Are several printing blankets 09 in the circumferential direction of the transfer cylinder 02 Arranged one behind the other, each have a leading and a trailing end 23 and 24 adjacent printing blankets 09 together. The holding device 26 can additionally have a slide, not shown, which in addition to the ends 23 and 24 in the gap 29 can be inserted and closes the gap 29 towards the outside. It is advantageous this slide is connected to the spindle 27, so that it when pivoting the spindle 27 is moved into or out of the gap 29. The width b29 of the gap 29 is at Use of such a slider is made correspondingly larger.

Die Kanäle 12; 13 der Formzylinder 03; 08 sind in bevorzugter Ausführung wie für den Kanal 14; 16; 17; 18 ebenfalls als zur Tangente der Mantelfläche um 30 bis 60°, insbesondere um ca. 45°, geneigte schmale Schlitze 12; 13 ausgeführt, welche eine Breite b12 (Fig. 1) im Bereich der Mantelfläche in Umfangsrichtung aufweisen, die größer als die doppelte Dicke der Druckform 11 ist. Für die Breite b12 des Schlitzes 12 gilt vorteilhafter Weise 1 mm ≤ b12 ≤ 5 mm, insbesondere b12 ≤ 3 mm. Für eine beispielhafte Prinzipdarstellung der Halteeinrichtung 33 für die Druckform 11 ist in der für das mehrteilige Drucktuch 09 dargestellten Fig. 3 lediglich das mehrteilige Drucktuch 09 (aus Trägerplatte 21 und Schicht 22) durch eine Druckform 11 mit abgebogenen, in den Kanal 12; 13 reichenden Enden zu ersetzen. Das Bezugszeichen für die Breite b29 entspräche der Breite b12 und das Bezugszeichen für den Übertragungszylinder 02 dem des Formzylinders, z. B. 03. Die Enden 23; 24 entsprächen den abgebogenen Enden der Druckform 11. The channels 12; 13 the forme cylinder 03; 08 are preferred as for the Channel 14; 16; 17; 18 also as to the tangent of the lateral surface by 30 to 60 °, in particular by approximately 45 °, slanted narrow slots 12; 13 executed, which one Have width b12 (FIG. 1) in the circumferential direction in the region of the lateral surface, which is larger than the double thickness of the printing form 11.
