Abstract

1. Method for manufacturing a paper feed roller with a foam body (4), which, during the formation of a cylindrical roller surface (5), is ground, whereupon after grinding a powder consisting of paper filler is applied to the roller surface.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Papiertransportwalze mit einem Schaumstoffkörper, der unter Bildung einer zylindrischen Walzenoberfläche abgeschliffen wird.The invention relates to a method for producing a paper transport roller with a foam body which is ground to form a cylindrical roller surface.

Ein derartiges Verfahren ist Gegenstand der älteren deutschen Patentanmeldung mit dem amtlichen Aktenzeichen P 36 12 631.4. Eine nach diesem Verfahren hergestellte Papiertransportwalze weist nach dem Abschleifen des Schaumstoffkörpers eine poröse Walzenoberfläche auf, deren Reibwert durch äußere Beanspruchungen und Verschmutzungen verhältnismäßig unbeein­flußbar ist. Allerdings ist der Reibwert dieser Papiertransport­walze verhältnismäßig hoch und läßt kaum einen Schlupf zwischen dem zu transportierenden Papier und der Papiertransportwalze zu. Ein derartiger Schlupf kann jedoch bei bestimmten Papiertransportarten und bei Unregelmäßigkeiten, wie z.B. Konizität der Papiertransportwalze erforderlich sein.Such a procedure is the subject of the older German patent application with the official file number P 36 12 631.4. A paper transport roller produced according to this method has a porous roller surface after grinding off the foam body, the friction coefficient of which is relatively uninfluenced by external stresses and soiling. However, the coefficient of friction of this paper transport roller is relatively high and hardly allows any slippage between the paper to be transported and the paper transport roller. However, such slippage can occur with certain types of paper transport and with irregularities such as Taper of the paper feed roller may be required.

Der Erfindung liegt die Aufgabe zugrunde, das eingangs ange­gebene Verfahren zur Herstellung einer Papiertransportwalze im Hinblick auf eine Verringerung des Reibwertes weiterzubilden, der auch bei längerer Beanspruchung der Walze im wesentlichen unverändert bleibt.The invention is based on the object of developing the above-mentioned method for producing a paper transport roller with a view to reducing the coefficient of friction, which remains essentially unchanged even when the roller is subjected to prolonged use.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß nach dem Abschleifen ein aus einem Papierfüllstoff bestehendes Pulver auf die Walzenoberfläche aufgebracht wird.This object is achieved in that after grinding a powder consisting of a paper filler is applied to the roller surface.

Unter Papierfüllstoff sind Zusatzstoffe zu verstehen, die üblicherweise bei der Papierherstellung dem Faserbrei zuge­setzt werden, um das Papier weich, geschmeidig und glatt zu machen. Zu diesen Zusatzstoffen zählen u. a. Aluminium­silikat (Kaolin), Titanoxid, Kalziumoxid, Magnesiumoxid und Gipse. Bei dem erfindungsgemäßen Verfahren wird bevor­zugt Pulver aus Magnesiumsilikat aufgebracht. Magnesiumsilikat ist auch unter der Bezeichnung "Talkum" bekannt.Paper filler is understood to mean additives which are usually added to the pulp during paper production in order to make the paper soft, smooth and smooth. These additives include a. Aluminum silicate (kaolin), titanium oxide, calcium oxide, magnesium oxide and plaster. In the method according to the invention, magnesium silicate powder is preferably applied. Magnesium silicate is also known under the name "talc".

Während in der Regel auf eine Vermeidung jeglicher Verschmutzun­gen einer Papiertransportwalze geachtet wird und vorhandene Ver­schmutzungen Qualitätsminderungen der Papiertransportwalze dar­stellen, wird gemäß dem erfindungsgemäßen Verfahren in über­raschender Weise ausgerechnet durch eine gezielte Verschmutzung der Walzenoberfläche deren Reibwert auf einen besonders langzeit­stabilen Wert verringert. Obwohl es zwar beispielsweise aus "Ullmann", Band 13, 1962, Seite 820, bekannt ist, insbesondere Talkum (Magnesiumsilikat) als Glättungs- und Schlüpfmittel für klebende oder rauhe Oberflächen zu verwenden, war daher nicht vorauszusehen, daß durch das Aufbringen des Pulvers auf die Walzenoberfläche die Qualität der Papiertransportwalze hinsichtlich der Langzeitstabilität des Reibwertes erheblich verbessert wird. Versuche zeigten jedoch, daß sich nach dem Aufbringen und Abstreifen überschüssiger Mengen des Pulvers der Reibwert auf einen um etwa 50 Prozent niedrigeren Wert verringert und diesen Wert auch noch nach langem Dauerbetrieb der Papiertransportwalze aufweist. Da es sich bei dem das Pulver bildenden Papierfüllstoff um einen papierverträglichen Stoff handelt, ist eine Beeinträchtigung der Eigenschaften des über die Papiertransportwalze laufenden Papieres ausgeschlossen.While care is generally taken to avoid any contamination of a paper transport roller and existing contaminations represent a reduction in quality of the paper transport roller, the method according to the invention surprisingly reduces the coefficient of friction to a particularly long-term stable value by targeted contamination of the roller surface. Therefore, although it is known, for example from "Ullmann", volume 13, 1962, page 820, in particular to use talc (magnesium silicate) as a smoothing and hatching agent for sticky or rough surfaces, it was therefore not foreseeable that the application of the powder on the roller surface, the quality of the paper transport roller is significantly improved with regard to the long-term stability of the coefficient of friction. Experiments showed, however, that after applying and wiping off excess amounts of the powder, the coefficient of friction is reduced to a value which is about 50 percent lower, and this value remains even after the paper transport roller has been in continuous operation for a long time. Since the paper filler forming the powder is a paper-compatible substance, the properties of the paper running over the paper transport roller are not impaired.

Schließlich ist ein weiterer Vorteil des erfindungsgemäßen Ver­fahrens in dem Fehlen jeglichen zusätzlichen konstruktiven Auf­wandes und in dem extrem geringen verfahrenstechnischen Aufwand zur Erzielung der langzeitstabilen Reibwertverringerung zu sehen.Finally, a further advantage of the method according to the invention can be seen in the lack of any additional structural outlay and in the extremely low outlay in terms of process engineering for achieving the long-term stable reduction in the coefficient of friction.

Aufgrund der Verringerung des Reibwertes auf einen langzeit­stabilen Wert ist im Rahmen der Erfindung eine Verwendung der nach dem erfindungsgemäßen Verfahren hergestellten Papier­transportwalze in einer Druckvorrichtung vorgesehen, wobei die Papiertransportwalze als Druckwalze zusammen mit einem Traktor zur Förderung von randgelochtem Endlospapier in einer Druckvorrichtung angeordnet ist. Der verringerte Reibwert der Walzenoberfläche ermöglicht dabei in vorteil­hafter Weise einen Schlupf zwischen dem Endlospapier und der Papiertransportwalze, so daß ein Ausreißen der Randlochung des Papiers aufgrund unterschiedlicher Fördergeschwindigkeiten des Traktors und der Papiertransportwalze verhindert wird.Due to the reduction in the coefficient of friction to a long-term stable value, the use of the paper transport roller produced by the method according to the invention is provided in a printing device within the scope of the invention, the paper transport roller being arranged as a printing roller together with a tractor for conveying perforated continuous paper in a printing device. The reduced coefficient of friction of the roller surface advantageously allows slippage between the continuous paper and the paper transport roller, so that the edge perforation of the paper is prevented from being torn out due to different conveying speeds of the tractor and the paper transport roller.

Im folgenden wird die Herstellung einer Papiertransportwalze gemäß dem erfindungsgemäßen Verfahren und ihre Verwendung anhand eines Beispiels unter Bezugnahme auf die Figur erläutert.In the following, the production of a paper transport roller according to the method according to the invention and its use will be explained using an example with reference to the figure.

Zunächst wird auf einem zylinderförmigen Tragkörper 1, der an beiden Stirnseiten Achsansätze 2 zum Einbau der Papiertrans­portwalze 3 in einen Drucker oder eine Schreibmaschine aufweist, ein hohlzylindrischer Schaumstoffkörper 4 aufgebracht. Dieser besteht vorzugsweise aus einem porösen Material mit geringer Restverformbarkeit und weist einen Außendurchmesser auf, der größer als der Solldurchmesser der fertigen Papiertransport­walze 3 ist. Nach dem Aufbringen des Schaumstoffkörpers 4 wird dieser unter Bildung einer zylindrischen Walzenoberfläche 5 bis auf den Solldurchmesser abgeschliffen. In einem folgenden Verfahrensschritt wird auf die geschliffene poröse Walzenober­fläche 5 ein Pulver, vorzugsweise aus dem Papierfüllstoff Talkum bestehend aufgebracht und überschüssige Mengen des Pulvers von der Walzenoberfläche 5 abgestreift.First of all, a hollow cylindrical foam body 4 is applied to a cylindrical support body 1, which has axle extensions 2 on both end faces for installing the paper transport roller 3 in a printer or a typewriter. This preferably consists of a porous material with low residual deformability and has an outer diameter that is larger than the target diameter of the finished paper transport roller 3. After the foam body 4 has been applied, it is ground down to the desired diameter to form a cylindrical roller surface 5. In a subsequent process step, a powder, preferably composed of talc paper filler, is applied to the ground porous roller surface 5 and excess amounts of the powder are stripped off the roller surface 5.

Die Figur zeigt weiterhin eine bevorzugte Verwendung der nach dem erfindungsgemäßen Verfahren hergestellten Papier­transportwalze 3 als Druckwalze, die zusammen mit einem Traktor 6 zur Förderung von randgelochtem Endlospapier 7 in einer Druckvorrichtung angeordnet ist. Das Endlospapier 7 ist von einem hier nicht dargestellten Papiervorrat kommend über den Traktor 6 geführt, der einen eigenen Antrieb 8 auf­weist. Endlosketten 9 des Traktors 6 greifen mittels Zähne 10 in die Randlochung des Papiers 7 und fördern dieses mit vorgegebener Papiervorschubgeschwindigkeit zu der Druckwalze 3. Eine Andrückrolle 11 drückt das Papier 7 gegen die Walzenober­fläche 5, so daß es an dieser eng anliegend mittels eines Druckkopfes 12 bedruckt werden kann. Die Druckwalze 3 weist ebenfalls einen eigenen Antrieb 13 auf. Die nach dem erfindungs­gemäßen Verfahren hergestellte Druckwalze 3 ermöglicht einen Schlupf zwischen der Walzenoberfläche 5 und dem Endlospapier 7, so daß ein Ausreißen der Randlochung aufgrund unterschiedlicher Fördergeschwindigkeiten des Traktors 6 und der Druckwalze 3 vermieden wird.The figure also shows a preferred use of the paper transport roller 3 produced by the method according to the invention as a printing roller, which together with a Tractor 6 for conveying continuous perforated paper 7 is arranged in a printing device. The continuous paper 7 comes from a paper supply, not shown here, over the tractor 6, which has its own drive 8. Endless chains 9 of the tractor 6 engage by means of teeth 10 in the edge perforation of the paper 7 and convey it to the printing roller 3 at a predetermined paper feed speed can be. The pressure roller 3 also has its own drive 13. The pressure roller 3 produced by the method according to the invention enables slippage between the roller surface 5 and the continuous paper 7, so that tearing out of the peripheral perforation due to different conveying speeds of the tractor 6 and the pressure roller 3 is avoided.
