Description

Die Erfindung betrifft einen Druckmaschinenzylinder gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a printing press cylinder according to the preamble of patent claim 1.

Bekannt ist, daß besonders bei schlanken Zylindern der Kanalschlag zu niederfrequenten Schwingungen in radialer Richtung anregt. Weiterhin wird durch die bei der Drehbewegung ausscherenden Massen eine Drehwinkelverlagerung eingeleitet, welche zu Unruhe im Antrieb führen. Eine Verstärkung des Trägheitsmomentes der Zylinder zur Verbesserung der Steifigkeit führt nicht immer zum gewünschten Erfolg, weil die damit verbundene Vergrößerung der trägen Masse die Schwingungsfrequenz und die Amplitude nicht entscheidend verbessert.It is known that, particularly in the case of slim cylinders, the channel impact excites low-frequency vibrations in the radial direction. Furthermore, a shift in the angle of rotation is initiated by the masses sheared during the rotary movement, which lead to unrest in the drive. An increase in the moment of inertia of the cylinders to improve the rigidity does not always lead to the desired success because the associated increase in the inertial mass does not decisively improve the oscillation frequency and the amplitude.

Gemäß DE-OS 30 12 060 sind schwingungsunempfindliche Zylinder für Druckmaschinen bekannt, die mehrstückig aufgebaut sind und bei denen Materialien verschiedener physikalischer Eigenschaften zur Schwingungsdämpfung verwendet werden.According to DE-OS 30 12 060 vibration-insensitive cylinders for printing machines are known, which are constructed in several pieces and in which materials of different physical properties are used to dampen vibrations.

Nachteilig bei diesem Zylinder ist, daß ein mehrstückiger Aufbau einen hohen Fertigungs- und Montageaufwand erfordert. Außerdem addieren sich bei einem mehrteiligen Aufbau die Fertigungstoleranzen. Durch den Einsatz von Materialien mit verschiedenen physikalischen Eigenschaften kann es bei Temperaturveränderungen vorkommen, daß sich die Zylinder in ihrer Form verziehen. Nachteilig ist ebenfalls, daß die zwischen den Kontaktflächen der einzelnen Bauteile vorgesehenen schwingungsdämpfenden Materialien sich auf die Formstabilität des Zylinders auswirken können.The disadvantage of this cylinder is that a multi-piece structure requires a high manufacturing and assembly costs. In addition, the manufacturing tolerances add up in a multi-part construction. By using materials with different physical Properties can occur when the temperature changes that the cylinder warp in shape. Another disadvantage is that the vibration-damping materials provided between the contact surfaces of the individual components can affect the dimensional stability of the cylinder.

Gemäß EP 01 03 101 ist eine Vorrichtung zur Reduzierung der durch die Kanalüberrollung in einem Druckwerkzylinder angeregten Biegeschwingungen bekannt, welcher mit Dämpfungsmasse gefüllt ist, im Inneren elastische Achsen angeordnet sind mit einer Zusatzmasse und daß diese Zusatzmasse außermittig angebracht ist und in Berührung mit dem Mantel steht.According to EP 01 03 101, a device for reducing the bending vibrations excited by the channel rollover in a printing unit cylinder is known, which is filled with damping mass, inside elastic axes are arranged with an additional mass and that this additional mass is attached off-center and is in contact with the jacket .

Nachteilig bei dieser Vorrichtung ist, daß die Zusatzmasse nicht zentrisch zur Mittelachse des Zylinders angeordnet ist, so daß ein Gegengewicht bzw. ein Auswuchten erforderlich ist. Weiterhin berührt die Zusatzmasse in einem Punkt den Zylindermantel, was insofern von Nachteil ist, als daß beim Auftreten von Schwingungen eine ständige mechanische Beanspruchung des Zylindermantels und der Zusatzmasse an immer der gleichen Stelle erfolgt, was zur Abflachung oder Ermüdung der Materialien und zum Verlust des Dämpfungseffektes führen kann. Ein mehrteiliger Aufbau erfordert ebenfalls einen hohen Fertigungs- und Montageaufwand.A disadvantage of this device is that the additional mass is not arranged centrally to the central axis of the cylinder, so that a counterweight or balancing is required. Furthermore, the additional mass touches the cylinder jacket at one point, which is disadvantageous in that, when vibrations occur, the cylinder jacket and the additional mass are always subjected to the same mechanical stress, which leads to flattening or fatigue of the materials and loss of the damping effect can lead. A multi-part construction also requires a lot of manufacturing and assembly work.

Weiterhin ist gemäß EP 01 03 102 eine weitere Variante der o. g. Vorrichtung bekannt geworden, welche an der Innenseite des Mantels des Druckwerkzylinders ein die Schwingungen übertragender Steg befestigt ist, der mit einem im Zylinderkanal liegenden Absorberstab verbunden ist. Der Absorberstab besitzt Zusatzmassen und ist in der Dämpfungsmasse eingebettet. Auch hier tritt neben den bereits schon genannten Nachteilen insbesondere der Nachteil ein, daß ein mehrteiliger Aufbau einen hohen Fertigungs- und Montageaufwand erfordert.Furthermore, according to EP 01 03 102, another variant of the above-mentioned device has become known, which is based on the On the inside of the jacket of the printing unit cylinder, a web which transmits the vibrations is fastened and which is connected to an absorber rod located in the cylinder channel. The absorber rod has additional masses and is embedded in the damping mass. Here too, in addition to the disadvantages already mentioned, there is in particular the disadvantage that a multi-part construction requires high manufacturing and assembly costs.

Der Erfindung liegt die Aufgabe zugrunde, einen Druckmaschinenzylinder mit Schwingungsdämpfung zu schaffen, welcher kostengünstig mit hoher Präzision herstellbar ist, dabei gute Dämpfungseigenschaften aufweist und einer Durchbiegung des Zylinders infolge Eigengewicht entgegenwirkt.The invention has for its object to provide a printing press cylinder with vibration damping, which is inexpensive to manufacture with high precision, has good damping properties and counteracts a deflection of the cylinder due to its own weight.

Erfindungsgemäß wird diese Aufgabe nach den Ansprüchen 1 und 11 gelöst. Zweckmäßige Merkmale sind den Unteransprüchen zu entnehmen.According to the invention, this object is achieved according to claims 1 and 11. Useful features can be found in the subclaims.

Die Vorteile der Erfindung bestehen insbesondere darin, daß der im Zylinderraum befindliche Kern eine Gegenmasse zum Zylindermantel bildet und das schwingungsdämpfende Material die Schwingungen umwandelt bzw. die Resonanzschwingungen so verstimmt, daß diese Schwingungen unschädlich werden. Durch die einteilig gegossene Ausführung des Druckmaschinenzylinders werden bei niedrigen Herstellungskosten geringe Fertigungstoleranzen ermöglicht. Durch die Anordnung eines koaxial um den Kern verlaufenden ringförmigen Steges, der mit dem Zylindermantel in Verbindung steht, wird eine axiale Durchbiegung des Druckmaschinenzylinders, insbesondere bei schlanken Zylindern, vermieden.The advantages of the invention consist in particular in that the core located in the cylinder space forms a countermass to the cylinder jacket and the vibration-damping material converts the vibrations or detunes the resonance vibrations so that these vibrations become harmless. The one-piece cast design of the printing press cylinder enables low manufacturing tolerances with low manufacturing costs. The arrangement of an annular web which runs coaxially around the core and which is connected to the cylinder jacket, axial deflection of the printing press cylinder, in particular in the case of slim cylinders, is avoided.

Durch die Anordnung von Kugeln bzw. vormontierten Kugelbehältern im Inneren des Druckmaschinenzylinders wird sowohl eine Gegenmasse zum Zylindermantel gebildet, als auch gleichzeitig ein schwingungsdämpfendes Material geschaffen. Bei der Verwendung von Kugelbehältern können dieselben unmittelbar in der Nähe der Stelle angebracht werden, an welcher die Schwingungen abgeleitet werden.The arrangement of balls or pre-assembled ball containers in the interior of the printing press cylinder not only forms a countermass to the cylinder jacket but also creates a vibration-damping material. When using spherical containers, they can be attached directly in the vicinity of the point at which the vibrations are derived.

Der Kern 7 weist beiderseits in Richtung der Zylinderachse Kernzapfen 9; 11 auf. Die Stirnseiten 3; 4 des Druckmaschinenzylinders 1 besitzen nach außen verlaufende Achszapfen 12; 13, die über Rollenlager 14; 16 in den Wänden eines Maschinengestells 17; 18 gelagert sind. Die beiden Kernzapfen 9; 11 sind über schwingungsdämpfendes Material, beispielsweise Buchsen 19; 21 aus Polyurethan, schwingungsdämpfend verbunden. Ein Antriebsrad 22 ist über Schrauben 23 unter Zwischenlage eines Distanzringes 24 mit dem Achszapfen 13 verbunden. Der Druckmaschinenzylinder 1 besitzt an seinen Stirnseiten 3; 4 Einfüllöffnungen 26 und besteht beispielsweise aus Stahlguß oder Grauguß. Verfahrenstechnisch gesehen wird der Kern 7 mit eingegossen. Der Formsand kann durch die Einfüllöffnungen 26 entfernt werden. Die Trennung der Kernzapfen 9; 11 von den Achszapfen 12; 13 erfolgt durch Spanabnahme nach der Vorbearbeitung.1 shows a longitudinal section through a printing press cylinder 1 according to the invention, but without a channel and without a gripper device. The device usually arranged in one or more channels, such as plate or blanket tensioning or gripping devices, is also generally not shown in the following embodiment variants. The cylinder channels are shown in FIGS. 4 and 8. The printing press cylinder 1 consists of a one-piece, rotationally symmetrical cast body, which comprises the cylinder jacket 2 and two end faces 3; 4 includes. Furthermore, belonging to the printing press cylinder 1, an approximately barrel-shaped core 7 extends in the interior of the printing press cylinder 1 in the direction of the cylinder axis 6, which core is firmly connected in the radial direction via an annular web 8 to the inner cylinder jacket 2. The core 7 has core pins 9 on both sides in the direction of the cylinder axis; 11 on. The end faces 3; 4 of the printing press cylinder 1 have axially extending journal 12; 13, the roller bearings 14; 16 in the walls of a machine frame 17; 18 are stored. The two core pins 9; 11 are over vibration-damping material, for example bushings 19; 21 made of polyurethane, vibration-dampened connection. A drive wheel 22 is connected to the journal 13 via screws 23 with the interposition of a spacer ring 24.

The molding sand can be removed through the filling openings 26. The separation of the core pin 9; 11 of the journal 12; 13 is done by chip removal after pre-processing.

Der Zylindermantel 2 des Druckmaschinenzylinders 1 wird durch den Kanalschlag, der Kanal wurde hier nicht dargestellt, zu Schwingungen angeregt. Diese Schwingungen werden über den ringförmigen Steg 8 an den Kern 7 weitergeleitet. Danach werden die Schwingungen in den Buchsen 19; 20 von mechanischer Arbeit in Wärmeenergie durch Reibung umgewandelt.The cylinder jacket 2 of the printing press cylinder 1 is excited to vibrate by the channel blow, the channel was not shown here. These vibrations are passed on to the core 7 via the annular web 8. Then the vibrations in the sockets 19; 20 converted from mechanical work into thermal energy by friction.

Der Vorteil dieser Ausführungsvariante besteht insbesondere in seinem einteiligen Aufbau, wobei der Kern 7 mit seinem ringförmigen Steg 8 als Gegendruckeinrichtung gleichzeitig gegen das Durchbiegen des Druckmaschinenzylinders 1 in radialer Richtung Verwendung findet.The advantage of this embodiment variant is in particular its one-piece construction, the core 7 with its annular web 8 being used as a counterpressure device at the same time against the bending of the printing press cylinder 1 in the radial direction.

Der Kern 27 ist in etwa zylinderförmig ausgebildet und ist in axialer Richtung 6 mit den Achszapfen 12; 13 fest verbunden. Der Kern 27 ist an seinen Stirnseiten teilweise mit den Stirnseiten 3; 4 des Druckmaschinenzylinders 1 und mit seiner Mantelfläche vollständig mit der Innenseite des Zylindermantels 2 des Druckmaschinenzylinders 1 durch schwingungsdämpfendes Material 28 verbunden.2 is a longitudinal section through a further embodiment of a one-piece according to the invention, consisting for example of cast steel or gray cast iron Printing machine cylinder 1 shown.

The core 27 is partially on its end faces with the end faces 3; 4 of the printing press cylinder 1 and with its outer surface completely connected to the inside of the cylinder casing 2 of the printing press cylinder 1 by vibration-damping material 28.

Der Kern 27 wurde verfahrenstechnisch gesehen, ebenfalls mit eingegossen. Nachdem der Gießsand durch die Einfüllöffnungen 26 entfernt worden ist, kann schwingungsdämpfendes Material 28 eingefüllt werden. Solches Material 28 kann beispielsweise aus Polyurethan, Schüttgut, beispielsweise Sand, aus zähflüssigen schwingungsdämpfenden Medien, beispielsweise hochviskoses Öl, bestehen. Bei der Verwendung von flüssigen Medien empfiehlt es sich, eine Membran zum Volumenausgleich zu verwenden, die jeweils mit den Einfüllöffnungen 26 in Verbindung steht.The core 27 was seen in terms of process technology, also cast in.

Der Vorteil dieser Ausführungsvariante besteht insbesondere in seinem einfachen einteiligen Aufbau, welcher geringe Fertigungstoleranzen ermöglicht.The advantage of this variant is in particular in its simple one-piece construction, which enables low manufacturing tolerances.

Gemäß Fig. 3 ist der Schnitt A-A nach Fig. 4 durch eine weitere Ausführungsvariante eines erfindungsgemäßen, aus Stahlguß bestehenden einstückigen Druckmaschinenzylinders 1 dargestellt. Aus den Fig. 3 und 4 ist ersichtlich, daß der im wesentlichen zylinderförmige Kern 29 über zwei gegenüberliegende, radial von der Zylinderachse 6 verlaufende Stege 31 mit der Innenseite des Zylindermantels 2 fest verbunden ist. Die Stege 31 sind winklig versetzt angeordnet zu den Zylinderkanälen 32. Die Stirnseiten 3; 4 des Druckmaschinenzylinders 1 sind mit den Achszapfen 12; 13 fest verbunden.According to FIG. 3, the section A-A according to FIG. 4 is represented by a further embodiment variant of a one-piece printing press cylinder 1 according to the invention consisting of cast steel. 3 and 4 that the essentially cylindrical core 29 is firmly connected to the inside of the cylinder jacket 2 by means of two opposite webs 31 which extend radially from the cylinder axis 6. The webs 31 are arranged offset at an angle to the cylinder channels 32. The end faces 3; 4 of the printing press cylinder 1 are with the journal 12; 13 firmly connected.

Der Kern 29 ist, wie bereits beim Ausführungsbeispiel nach Fig. 2 beschrieben, eingegossen worden. Ebenfalls kommt das schwingungsdämpfende Material 28 gemäß Fig. 2 zur Anwendung.As already described in the exemplary embodiment according to FIG. 2, the core 29 has been cast in. The vibration-damping material 28 according to FIG. 2 is also used.

Gemäß Fig. 5 ist ein Längsschnitt durch eine weitere Ausführungsvariante eines einstückigen erfindungsgemäßen Druckmaschinenzylinders 1 dargestellt. Der im wesentlichen zylinderförmige Kern 33 ist völlig mit schwingungsdämpfendem Material 34 umgeben. Das Material 34 ist demzufolge andererseits mit dem Zylindermantel 2 und den Stirnseiten 3; 4 des Druckmaschinenzylinders 1 in Berührung. Die Stirnseiten 3; 4 sind fest mit den Achszapfen 12; 13 verbunden.5 shows a longitudinal section through a further embodiment variant of a one-piece printing press cylinder 1 according to the invention. The essentially cylindrical core 33 is completely surrounded by vibration-damping material 34. The material 34 is consequently on the other hand with the cylinder jacket 2 and the end faces 3; 4 of the printing press cylinder 1 in contact. The end faces 3; 4 are fixed to the journal 12; 13 connected.

Verfahrenstechnisch gesehen ist der Kern 33 in einem Guß mit dem gesamten Druckmaschinenzylinder 1 gegossen. Nach dem Entfernen des Gießsandes durch die Einfüllöffnungen 26 und dem Umgießen des Kerns 33 mit schwingungsdämpfendem Material 34 werden die Gußstege von dem Zylindermantel 2 durch Ausbohren getrennt, so daß zwischen dem Kern 33 und den Stirnseiten 3; 4 keine metallische Verbindung mehr besteht.In terms of process technology, the core 33 is cast in one casting with the entire printing press cylinder 1. After the casting sand has been removed through the filling openings 26 and the core 33 has been cast with vibration-damping material 34, the casting webs are separated from the cylinder jacket 2 by drilling out, so that between the core 33 and the end faces 3; 4 there is no longer any metallic connection.

Der Zylindermantel 2 des Druckmaschinenzylinders 1 wird durch den Kanalschlag, der Kanal wurde hier nicht dargestellt, zu Schwingungen angeregt. Diese Schwingungen werden in dem schwingungsdämpfenden Material 34 umgewandelt. Der Kern 33 dient als Gegenmasse zum Zylindermantel 2. Als schwingungsdämpfendes Material 34 kann hierbei von Vorteil Polyurethan mit Metallgranulat zur Masseangleichung eingesetzt werden.The cylinder jacket 2 of the printing press cylinder 1 is excited to vibrate by the channel blow, the channel was not shown here. These vibrations are converted in the vibration damping material 34. The core 33 serves as a countermass to the cylinder jacket 2. As a vibration-damping material 34, polyurethane with metal granules can advantageously be used to equalize the mass.

Der Vorteil dieser Ausführungsvariante besteht insbesondere darin, daß neben der einstückigen Ausführung des Druckmaschinenzylinders 1 der Kern 33 metallisch nicht mit dem Zylindermantel 2 verbunden ist. Somit hat der Druckmaschinenzylinder 1 selbst weniger schwingungsdämpfende Masse. Die Schwingungen des Zylindermantels 2 können nur indirekt und nur über das schwingungsdämpfende Material 34 an den Kern 33 gelangenThe advantage of this embodiment variant is in particular that, in addition to the one-piece design of the printing press cylinder 1, the core 33 is not metallically connected to the cylinder jacket 2. Thus, the printing press cylinder 1 itself has less vibration-damping mass. The vibrations of the cylinder jacket 2 can only reach the core 33 indirectly and only via the vibration-damping material 34

Gemäß Fig. 6 ist ein Längsschnitt durch eine weitere Ausführungsvariante eines erfindungsgemäßen einstückigen Druckmaschinenzylinders 1 dargestellt. Der Kern 36 ist in etwa zylinderförmig ausgebildet und besitzt in axialer Richtung 6 zwei Kernzapfen 9; 11. Der Zylindermantel 2 besitzt an seinen Stirnseiten 3; 4 jeweils Achszapfen 12; 13.6 shows a longitudinal section through a further embodiment variant of a one-piece printing press cylinder 1 according to the invention. The core 36 is in approximately cylindrical and has two core pins 9 in the axial direction 6; 11. The cylinder jacket 2 has 3 on its end faces; 4 each journal 12; 13.

Der Kern 36 wurde somit mit größtmöglicher Masse in einem Stück in dem Zylinder gegossen. Nach dem Umgießen des Kerns 36 mit schwingungsdämpfendem Material 34 wird der Kern 6 durch Ausbohren der Gußstege vom Zylinder getrennt, so daß der Kern 36 und die Kernzapfen 9; 11 keine metallische Verbindung zum Zylindermantel 2 bzw. zu den Stirnseiten 3; 4 haben. Der Raum zwischen den Kernzapfen 9; 11 und den Achszapfen 12; 13 wird nach dem Freibohren ebenfalls mit schwingungsdämpfendem Material 34 gefüllt.The core 36 was thus cast in one piece in the cylinder with the greatest possible mass. After casting around the core 36 with vibration-damping material 34, the core 6 is separated from the cylinder by drilling out the casting webs, so that the core 36 and the core pin 9; 11 no metallic connection to the cylinder jacket 2 or to the end faces 3; Have 4. The space between the core pins 9; 11 and the journal 12; 13 is also filled with vibration-damping material 34 after drilling.

Gemäß Fig. 7 ist eine im Längsschnitt erfindungsgemäße Lösung für einen einteiligen Druckmaschinenzylinder 1 mit Schwingungsdämpfung dargestellt. Der Zylindermantel 2 ist mit den Stirnseiten 3; 4 und die Stirnseiten 3; 4 sind mit den in axialer Richtung verlaufenden Achszapfen 12; 13 fest verbunden. In dem Raum, der von dem Zylindermantel 2 und den Stirnseiten 3; 4 des Druckmaschinenzylinders 1 gebildet wird, sind Kugeln 37 eingefüllt. Die Kugeln 37 besitzen vorzugsweise einen Durchmesser von 2,5 bis 3 mm und sollten aus Stahl sein. Die Kugeln 37 können durch die Einfüllöffnungen 26 eingebracht werden. Die Kugeln 37 dienen sowohl als Kern als auch als schwingungsdämpfendes Material. Das Verdichten der Kugeln 37 kann durch Rütteln erfolgen. Zusätzlich kann noch eine Vorspann-Einrichtung im Inneren des Druckmaschinenzylinders 1 angeordnet sein, welche die Kugeln 37 im Bedarfsfalle weiter verdichtet. Der Zylinder kann aber auch mehrteilig ausgeführt sein.7 shows a longitudinal section of the solution according to the invention for a one-piece printing press cylinder 1 with vibration damping. The cylinder jacket 2 is with the end faces 3; 4 and the end faces 3; 4 are with the axles extending in the axial direction 12; 13 firmly connected. In the space from the cylinder jacket 2 and the end faces 3; 4 of the printing press cylinder 1 is formed, balls 37 are filled. The balls 37 preferably have a diameter of 2.5 to 3 mm and should be made of steel. The balls 37 can be introduced through the filling openings 26. The balls 37 serve both as a core and as a vibration-damping material. The balls 37 can be compacted by shaking. In addition, a pretensioner can be installed in the Be arranged inside the printing press cylinder 1, which further compresses the balls 37 if necessary. The cylinder can also be made in several parts.

Durch den Kanalschlag wird der Zylindermantel 2 zu Schwingungen angeregt. Diese Schwingungen werden auf die an der Innenseite des Zylindermantels 2 anliegenden Kugeln 37 übertragen. Durch die verlustbehafteten Stoß- und Bewegungsvorgänge der aneinanderliegenden Kugeln 37 nehmen die Schwingungen mehr und mehr ab. Die Dämpfungswirkung kann noch erhöht werden, wenn zusätzlich noch viskose Dämpfungsanteile, wie Öle oder Fette verwendet werden.The cylinder jacket 2 is excited to vibrate by the channel blow. These vibrations are transmitted to the balls 37 abutting the inside of the cylinder jacket 2. Due to the lossy impact and movement processes of the balls 37 lying against one another, the vibrations decrease more and more. The damping effect can be increased if additional viscous damping components such as oils or fats are used.

Gemäß Fig. 8 ist mit dem Querschnitt durch einen Druckmaschinenzylinder eine weitere Ausführungsvariante nach Fig. 7 gezeigt. Der Zylindermantel 2 ist mit Zylinderkanälen 32 dargestellt. Der Druckmaschinenzylinder 1 ist gemäß Fig. 7 ausgeführt, mit der Besonderheit, daß nicht der gesamte Innenraum, der durch den Zylindermantel 2 und die Stirnseiten 3; 4 begrenzt ist, mit Kugeln 37 ausgefüllt ist, sondern daß zwei mit Kugeln gefüllte Behälter 38 in axialer Richtung 6 in der Nähe der Zylinderkanäle 32 an der Innenseite des Zylindermantels 2 angebracht sind. Der Zylinderkanal ist der Bereich, in dem die Schwingungen erzeugt werden. Es können ein oder mehrere Kugelbehälter montiert sein. Vorteilhaft ist es auch, mehrere Kugelbehälter so anzubringen, daß ein zusätzliches Auswuchten entfallen kann. Zweckmäßig ist, Stahlkugeln mit einem Durchmesser von 2,5 bis 3 mm einzusetzen.According to FIG. 8, a further embodiment variant according to FIG. 7 is shown with the cross section through a printing press cylinder. The cylinder jacket 2 is shown with cylinder channels 32. The printing press cylinder 1 is designed according to FIG. 7, with the special feature that not the entire interior space, which is caused by the cylinder jacket 2 and the end faces 3; 4 is limited, is filled with balls 37, but that two containers 38 filled with balls are attached in the axial direction 6 in the vicinity of the cylinder channels 32 on the inside of the cylinder jacket 2. The cylinder channel is the area in which the vibrations are generated. One or more ball containers can be installed. It is also advantageous to attach several ball containers so that additional balancing can be omitted. It is advisable to use steel balls with a diameter of 2.5 to 3 mm.

Der Druckmaschinenzylinder kann einteilig oder auch mehrteilig aufgebaut sein. Er muß eine stirnseitige Öffnung zum Einbringen und Montieren der Kugelbehälter besitzen.The printing press cylinder can be constructed in one part or in several parts. It must have an opening at the front for inserting and mounting the ball container.

Die gefüllten Kugelbehälter werden durch die stirnseitigen Öffnungen im Druckmaschinenzylinder so angebracht, daß diese mit einer Fläche am inneren Zylindermantel fest anliegen. Die Kugelbehälter können aus Blech und am Zylindermantel festgeschraubt oder festgeklemmt sein.The filled ball containers are attached through the front openings in the printing press cylinder so that they lie firmly against the inner surface of the cylinder. The ball containers can be screwed or clamped from sheet metal and to the cylinder jacket.
