Abstract

Appts. for the intaglio printing of textiles has a printing roller with an elastic PVA surface designed to resist mechanical stress and chemicals, partic. printing ink solvents. The textile material is fed between this roller and a counter-pressure roller and subjected to pressure.

Description

Vorrichtung zum Bedrucken von Warenbahnen Die Erfindung betrifft eine Vorrichtung zum Bedruck von Warenbahnen im Tiefdruckverfahren, bestehend aus einer Druckwalze mie elastischer Oberfläche und iner Gegenwalze, zwischen denen die Warenbahn unter Pressung hindurchgeführt wird.Device for printing webs of material The invention relates to a Device for printing webs of material using the gravure printing process, consisting of a Pressure roller with an elastic surface and a counter roller, between which the web of material is passed under pressure.

Drackwalzen mit elastischer Oberfläche haben den Vorteil, daß mit ihnen auch unebene Warenbahnen, wie z.3. grob gewebte Textilbahnen, einwandfrei ausgedruckt werden können, während bei nicht elastischen Druckwalzen in diesem Fall nur die Fadenkreuzungspunkte richtig bedruckt werden.Pressure rollers with an elastic surface have the advantage that with them also uneven webs, such as e.g. 3. coarsely woven textile panels, flawless can be printed out, while with non-elastic pressure rollers in this case only the crosshair points are correctly printed.

Ähnliche Pro-bleme bestehen beim Drucken von starren Oberflächen, wie z.B. Brettern aus Holz, Stahl oder dergleichen.Similar problems exist when printing rigid surfaces, such as boards made of wood, steel or the like.

Die bekannten Druckwalzen mit elastischer Oberfläche haben den Nachteil, daß sie gegenüber den Lösungsmitteln der Druckfarbe nicht hinreichend formbeständig sind, so daß dadurch die Druckproflierung der Walze relativ schnell unbrauchbar wird.The known pressure rollers have an elastic surface the Disadvantage that they are insufficient with respect to the solvents in the printing ink are dimensionally stable, so that the pressure profile of the roller relatively quickly becomes unusable.

Der r£indung liegt daher die Aufgabe zugrunde bei einer Vorrichtung zum Bedrucken von Warenbannen im Tiefdruckverfahren, bestehend aus einer Drackwalze mit elastischer Oberfläche und einer Gegendruckwalze, zwischen denen die Warenbahn unter Pressung hindurchgeführt wird, die Druckwalze mit elastischer Oberfläche so auszubilden, daß diese sowohl mechanischen als auch chemischen Einflüssen, insbesondere gegenüber den Lösungsmitteln der Druckfarbe standhält.The rounding is therefore based on the task of a device for printing goods banners using the gravure printing process, consisting of a pressure roller with an elastic surface and a counter-pressure roller, between which the web of material is passed under pressure, the pressure roller with elastic surface so train that this both mechanical and chemical influences, in particular withstands the solvents of the printing ink.

Die Losu:g dieser Aufgabe besteht darin, daß die elastische Oberfläche der Druckwalze aus Polyvinylalkohol besteht.The losu: g of this task is that the elastic surface the platen is made of polyvinyl alcohol.

Versuche haben ergeben, daß eine Druckwalze mit einer solchen elastischen Oberfläche außerordentlich widerstandsfähig gegenüber mechanischen und chemischen Einflüssen ist.Experiments have shown that a pressure roller with such an elastic Surface extremely resistant to mechanical and chemical Influences is.

Die Herstellung- der erfindungsgemäßen Druckwalze kann wie folgt geschehen : Von einem in natür-licher Größe ausgeführten urmodell in s.B. einer Druckwalze wird ein nahtloses Schlauchmodell aus elastisch dehnbarem Werkstoff abgeformt und nach dem unter elastischer Dehnung erfolgenden Abziehen vom Urmodeil als wiederholt verwendbare Hohlform benutzt. In diese Hohlform, die eine negativ profilierte Tnnenfläche aufweist, wird dann ein Kern eingelegt und der verbleibende Borwraum mit Polyvinylalkohol ausgefüllt. Anschließend wird die Hohlform wieder unter elastischer Dehnung nach Verfestigung des Polyvinylalkhhols von dem dabei entstehenden, einen Walzenmantel bildenden Werkstück abgezogen, das dann eine profilierte Außenfläche aufweist. Bs handelt sich dabei um eine naturgetreue Kopie des Urmodells aus beispielsweise Kupfer.The printing roller according to the invention can be produced as follows : From a natural-size original model in s.B. a pressure roller a seamless tube model made of elastically stretchable material is molded and after being pulled from the original part under elastic elongation as repeated usable hollow form used. In this hollow form, one negative Has a profiled inner surface, a core is then inserted and the remaining one Boring space filled with polyvinyl alcohol. Then the hollow shape is again under elastic elongation after solidification of the polyvinyl alcohol of the thereby resulting, a roll shell forming workpiece is withdrawn, which is then profiled Has outer surface. Bs is a true-to-life copy of the master model made of copper, for example.
