Description

Die Erfindung bezieht sich auf eine Walze für Druckmaschinen, Kopierer, Film- und Fotoentwicklungsmaschinen oder dergleichen nach dem Oberbegriff des Anspruchs 1.The invention 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 feuchtigkeitsaufsagenden Stoff oder Kunststoffüberzug versehen.In printing presses, 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 with washing rollers pure rubber or rubber-like Material is used, dampening rollers are usually covered with a moisture-absorbing material or plastic coating.

Aus US-A-4 492 012, FR-A-1 332 407, US-A-3 808 657 und Patent Abstracts of Japan Volume 10, Nr. 122 (M-476) (2179), 7. Mai 1986 und JP-A-60 250991 ist bekanntgeworden, einer vulkanisierbaren Mischung eines elastomeren Materials für eine Walze der eingangs genannten Art Kunststofffasern zuzumischen. Bei der US-A-4 492 012 werden Polyamidfasern in einem Anteil von 5 bis 45% der Gesamtmenge, vorzugsweise 25%, beigemischt. Die Fasern haben eine Mindestlänge von etwa 4 mm. In der Mischung nach der US-A-3 808 652 haben die Fasern eine Länge von etwa 1,2 cm. Bei der Mischung nach der japanischen Druckschrift bewegt sich die Länge der Fasern zwischen 0,05 und 1 mm.From US-A-4 492 012, FR-A-1 332 407, US-A-3 808 657 and Patent Abstracts of Japan Volume 10, No. 122 (M-476) (2179), May 7, 1986 and JP -A-60 250991 has become known to mix plastic fibers into a vulcanizable mixture of an elastomeric material for a roller of the type mentioned at the beginning. In US-A-4,492,012, polyamide fibers are mixed in a proportion of 5 to 45% of the total amount, preferably 25%. The fibers have a minimum length of about 4 mm. In the blend of US-A-3 808 652 the fibers are about 1.2 cm in length. When mixing according to the Japanese publication, the length of the fibers ranges between 0.05 and 1 mm.

Der Erfindung liegt die Aufgabe zugrunde, eine Walze für Druckmaschinen, Kopierer, Film- und Fotoentwicklungsmaschinen oder dergleichen zu schaffen, die eine wirksame Funktion gewährleistet, insbesondere eine definierte Flüssigkeitsführung gestattet und ggf. leicht gereinigt werden kann.The invention has for its object to provide a roller for printing machines, copiers, film and photo processing machines or the like, which is effective Function guaranteed, in particular a defined liquid flow allowed and can be easily cleaned if necessary.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of patent claim 1.

Bei der erfindungsgemäßen Walze wird in üblicher Weise eine geeignete Gummimischung verwendet, wobei die Zusammensetzung bzw. ihre physikalischen Eigenschaften vom Einsatzzweck abhängen. Eine Waschwalze wird aus hoch abriebfestem relativ hartem Material geformt, während eine Feuchtwalze aus weitaus weicherem Material hergestellt wird. Der Anteil der Fasern beträgt 2 bis 25%. Bei Waschwalzen wird der Anteil der Fasern im unteren und bei Feuchtwalzen im oberen Bereich liegen. Sie geben der Oberfläche einer Walze eine Struktur, die der Feuchtigkeitsführung dienlich ist. Die Fasern sind relativ fein. Sie haben einen Durchmesser zwischen 15 bis 30 µm, wodurch ein kratzender Effekt vermieden wird. Sie sind auch verhältnismäßig kurz, im Bereich von etwa 0,2 bis 0,8 mm, vorzugsweise 0,5 mm Länge. Dadurch können sie sich in gewünschter Weise gleichmäßig verteilen. Die Fasern können in der beschriebenen Struktur und Abmessung leicht in gewünschter Weise abgeschliffen werden, wenn die Walzen geschliffen werden.In the roller according to the invention, a suitable rubber mixture is used in the usual way, the composition and its physical properties depending on the intended use. A washing roller is molded from highly abrasion-resistant, relatively hard material, while a dampening roller is made from much softer material. The proportion of fibers 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. They give the surface of a roller a structure that is conducive to moisture management. The fibers are relatively fine. They have a diameter between 15 and 30 µm, which avoids a scratching effect. They are also relatively short, in the range of about 0.2 to 0.8 mm, preferably 0.5 mm in length. This allows them to be distributed evenly in the desired manner. The fibers can easily in the structure and dimensions described in the desired Way when the rollers are ground.

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 durch den Anteil der zugemischten Fasern einstellen.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 erfindungsgemäße Walze kann auch ohne weiteres gereinigt werden. 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 Unterbrechung in der Produktion entsteht.The roller according to the invention can also be easily 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.

Als Fasern werden geeignete Kunststoffasern verwendet, die völlig unpräpariert sind. Damit sich jedoch eine wirksame Verbindung mit dem elastomeren Material der Walze ergibt, wird der Mischung ein Harz oder eine harzähnliche Substanz zugefügt. Bei einer Ausgestaltung der Erfindung bestehen die Fasern vorzugsweise aus Polyamid.Suitable plastic fibers that are completely unprepared are used as fibers. However, for an effective connection with the elastomeric material of the roller, a resin or a resin-like substance is added to the mixture. In one embodiment of the invention, the fibers are preferably made of polyamide.

Die Erfindung wird nachfolgend anhand von Zeichnungen näher erläutert.

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 etwa 0,5 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 aus 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 approximately 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 a bit above the surface, as is how 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.
