Description

Die Neuerung bezieht sich auf eine Walze für Druckmaschinen, Kopierer, Film- und Fotoentwicklungsmaschinen oder dergleichen nach dem Oberbegriff des Anspruchs 1.The innovation relates to a roller for printing machines, copiers, film and photo processing machines or the like according to the preamble of claim 1.

In Druckmaschinen, Kopierern oder dergleichen werden Walzen für vielfältige Zwecke eingesetzt, so auch mit dem Ziel, Feuchtigkeit zu fördern. Dies geschieht beispielsweise bei Waschwalzen in Druckmaschinen. Sie bringen eine benzinöse Waschflüssigkeit auf das Drucktuch. Eine andere Einsatz­weise sind die Feuchtwerke bei Offsetmaschinen. Während bei Waschwalzen reines Gummi- oder gummiartiges Material verwen­det wird, werden Feuchtwalzen normalerweise mit einem feuch­ tigkeitsaufsaugenden Stoff oder Kunststoffüberzug ver­sehen.In printing machines, copiers or the like, rollers are used for a variety of purposes, including with the aim of promoting moisture. This happens, for example, with washing rollers in printing machines. They bring a petrol-like washing liquid onto the printing blanket. Another application is the dampening system in offset machines. While washing rollers use pure rubber or rubber-like material, dampening rollers are usually used with a damp absorbent fabric or plastic cover.

In beiden Fällen weisen die feuchtigkeitsfördernden Walzen nicht unerhebliche Nachteile auf. Bei Waschwalzen besteht die Gefahr, daß zu viel Waschflüssigkeit mitgenommen wird und das Drucktuch zu feucht wird. Außerdem besteht die Ge­fahr, daß Waschflüssigkeit in die Umgebung verspritzt wird. Bei Feuchtwalzen in Offsetdruckmaschinen besteht die Gefahr, daß sich Farbe am Überzug aufbaut, so daß eine unregel­mäßige Wasserführung die Folge ist. Ein Farbaufbau macht den Austausch des textilen Überzugs notwendig. Die ent­sprechenden Montagearbeiten sind aufwendig und bedingen den Stillstand der Maschine.In both cases, the moisture-promoting rollers have significant disadvantages. In the case of washing rollers, there is a risk that too much washing liquid is taken along and the printing blanket becomes too moist. There is also a risk that washing liquid is splashed into the environment. In the case of dampening rollers in offset printing machines, there is a risk that ink builds up on the coating, so that irregular water flow is the result. A color scheme makes it necessary to replace the textile cover. The corresponding assembly work is complex and requires the machine to come to a standstill.

Der Neuerung liegt daher die Aufgabe zugrunde, eine Walze für Druckmaschinen, Kopierer, Film- und Fotoentwicklungsmaschinen oder dergleichen zu schaffen, die eine definierte Flüssigkeits­führung gestattet und gegebenenfalls leicht gereinigt werden kann.The innovation is therefore based on the task of creating a roller for printing machines, copiers, film and photo processing machines or the like, which allows a defined liquid flow and can be easily cleaned if necessary.

Diese Aufgabe wird durch die Merkmale des Kennzeichnungs­teils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Bei der neuerungsgemäßen Walze wird in üblicher Weise eine geeignete Gummimischung verwendet, wobei die Zusammen­setzung bzw. ihre physikalischen Eigenschaften vom Einsatz­ zweck abhängen. Eine Waschwalze wird aus hoch abrieb­festem relativ hartem Material geformt, während eine Feuchtwalze aus weitaus weicherem Material hergestellt wird. Dem elastomeren Material wird eine vorgegebene Menge an unbehandelten kurzen feinen Kunststoffasern zugemischt. Der Anteil der Fasern beträgt nach einer Aus­gestaltung der Neuerung an der Gesamtmenge einer Mischung 2 bis 25 %. Bei Waschwalzen wird der Anteil der Fasern im unteren Bereich und bei Feuchtwalzen im oberen Bereich liegen. Die Fasern geben der Oberfläche einer Walze eine Struktur, die der Feuchtigkeitsführung dienlich ist. Die Fasern sind relativ fein. Nach einer Ausgestaltung der Neuerung beträgt ihr Durchmesser etwa zwischen 15 bis 30µ Dadurch wird ein kratzender Effekt vermieden. Sie sind auch verhältnismäßig kurz, etwa im Bereich von 0,2 bis 0,8 mm, vorzugsweise im Bereich von 0,5 mm Länge. Dadurch stehen sie nur eine begrenzte Länge aus der Walzenoberfläche vor und können ebenfalls keine nachteiligen Wirkungen verur­sachen.In the roller according to the invention, a suitable rubber mixture is used in the usual way, the composition or its physical properties depending on the use depend on purpose. A washing roller is molded from highly abrasion-resistant, relatively hard material, while a dampening roller is made from much softer material. A predetermined amount of untreated, short, fine plastic fibers is mixed into the elastomeric material. According to one embodiment of the innovation, the proportion of fibers in the total amount of a mixture is 2 to 25%. In the case of washing rollers, the proportion of fibers will be in the lower region and in the case of dampening rollers in the upper region. The fibers give the surface of a roller a structure that is conducive to moisture management. The fibers are relatively fine. According to an embodiment of the innovation, its diameter is approximately between 15 to 30µ. This avoids a scratching effect. They are also relatively short, for example in the range from 0.2 to 0.8 mm, preferably in the range of 0.5 mm in length. As a result, they only protrude from the roll surface for a limited length and cannot cause any disadvantageous effects either.

Die beschriebene Faserzumischung hat eine feine bürsten­artige Walzenoberfläche zur Folge, die einerseits keine nachteiligen Wirkungen auf das Druckverfahren hat, ande­rerseits jedoch die gewünschte Flüssigkeitsführung gewähr­leistet. Der Grad der Flüssigkeitsführung läßt sich im übrigen einstellen durch den Anteil der zugemischten Fasern.The fiber admixing described results in a fine brush-like roller surface, which on the one hand has no adverse effects on the printing process, but on the other hand ensures the desired liquid flow. The degree of liquid guidance can also be adjusted by the proportion of the fibers added.

Die neuerungsgemäße Walze hat auch noch den Vorteil, daß sie gereinigt werden kann. Kommt es in einer Offsetdruck­maschine zu einer Farbabgabe auf die Feuchtwalze, kann der Bedienungsmann die Farbe ohne weiteres entfernen, ohne daß ein Ausbau der Walze erforderlich ist. Selbst der Aus­bau der Walze läßt sich jedoch innerhalb relativ kurzer Zeit bewerkstelligen, so daß nur eine minimale Unterbre­chungszeit in der Produktion entsteht. Die neuerungsgemäße Walze kann auch abgearbeitet werden, beispielsweise durch Schleifen oder dergleichen, ohne daß sich an der Eigen­schaft ihrer wasserführenden Oberfläche etwas ändert. Dies liegt daran, daß die Fasern insgesamt der Mischung für die Walze zugesetzt und nicht etwa nur der Walzenoberfläche zu­geordnet sind.The roller according to the innovation also has the advantage that it can be cleaned. If ink is applied to the dampening roller in an offset printing press, the operator can easily remove the ink without having to remove the roller. Even the roll can be removed within a relatively short time, so that there is only a minimal interruption in production. The roller according to the invention can also be machined, for example by grinding or the like, without changing the properties of its water-carrying surface. This is because the fibers as a whole are added to the mixture for the roller and are not only assigned to the roller surface.

Als Fasern werden geeignete Kunststoffasern verwendet, die völlig unpräpariert sein können. Damit jedoch eine wirksame Verbindung mit dem elastomeren Material der Walze erfolgt, wird der Mischung ein Harz oder eine harzähnliche Substanz zugefügt. In besonders vorteilhafter Weise sind die Fasern aus Polyamid.Suitable plastic fibers are used as fibers, which can be completely unprepared. However, for an effective connection with the elastomeric material of the roller, a resin or a resin-like substance is added to the mixture. The fibers are particularly advantageously made of polyamide.

Es ist an sich bekannt, Gummimischungen für Schläuche, Transportbänder oder dergleichen Kunststoffasern zuzu­mischen. Dies geschieht in der Absicht, die Festigkeit des Materials zu verbessern.It is known per se to mix in rubber mixtures for hoses, conveyor belts or the like plastic fibers. This is done with the intention of improving the strength of the material.

Die Neuerung wird nachfolgend anhand von Zeichnungen näher erläutert.

  • Fig. 1 zeigt schematisch eine Offsetdruckmaschine.
  • Fig. 2 zeigt die Draufsicht auf eine Feuchtwalze der Maschine nach Fig. 1.
  • Fig. 3 zeigt vergrößert einen Teilschnitt der Feucht­walze nach Fig. 2.
The innovation is explained in more detail below with the aid of drawings.
  • Fig. 1 shows schematically an offset printing machine.
  • FIG. 2 shows the top view of a dampening roller of the machine according to FIG. 1.
  • 3 shows an enlarged partial section of the dampening roller according to FIG. 2.

Die Offsetdruckmaschine nach Fig. 1 weist in bekannter Weise einen Formzylinder 10, einen mit einem Gummituch bespannten Übertragungszylinder 11, einen Druckzylinder 12, Farbwalzen 13 sowie Feuchtwalzen 14 auf. Zu bedruckendes Papier 15 wird zwischen Übertragungszylinder und Druckzy­linder geführt.1 has a forme cylinder 10, a transfer cylinder 11 covered with a rubber blanket, a printing cylinder 12, inking rollers 13 and dampening rollers 14 in a known manner. Paper 15 to be printed is guided between the transfer cylinder and the printing cylinder.

In Fig. 2 ist eine Feuchtwalze 14 zu erkennen. Sie besteht aus einer Gummimischung aus natürlichem oder Nitrilkautschuk vorgegebener Härte. Dieser Gummimischung sind Polyamidfasern einer Länge von etwa0,5 mm und einem Durchmesser von 15 bis 30 µ zugemischt. Ihr Anteil an der Gesamtmaterialmenge be­trägt etwa 15 %. Die Fasern sind in Fig. 2 bei 16 angedeu­tet. Sie stehen etwas über die Oberfläche vor, wie sich au Fig. 3 ergibt. Das Herausstehen wird naturgemäß durch ihre Länge begrenzt. Die Feuchtwalzen des beschriebenen Auf­baus gewährleisten eine optimale Flüssigkeitsführung, wo­bei diese abhängt vom Anteil der zugemischten Fasern. Kommt es gegebenenfalls zu einem Farbauftrag auf den Feuchtwalzen 14, können diese relativ einfach und rasch gereinigt werden.A dampening roller 14 can be seen in FIG. It consists of a rubber mixture of natural or nitrile rubber with a specified hardness. Polyamide fibers with a length of about 0.5 mm and a diameter of 15 to 30 µ are mixed into this rubber mixture. Their share in the total amount of material is about 15%. The fibers are indicated at 16 in FIG. 2. They protrude slightly above the surface, as is Fig. 3 results. The protrusion is naturally limited by its length. The dampening rollers of the structure described ensure optimal liquid guidance, which depends on the proportion of the fibers added. If there is a possible application of ink to the dampening rollers 14, they can be cleaned relatively easily and quickly.

Die beschriebene Walze ist nicht beschränkt auf ihren Ein­satz in Druckmaschinen oder dergleichen, sondern kann über­all dort verwendet werden, wo Feuchtigkeit bzw. Flüssigkeit mit Hilfe einer Walze auf einen anderen Gegenstand über­tragen werden soll.The roller described is not limited to its use in printing presses or the like, but can be used wherever moisture or liquid is to be transferred to another object with the aid of a roller.
