Abstract
Anlage zur Herstellung von Wellpappe mit einem integrierten digitalen Druckwerk 9 zum Bedrucken von glatten Papierbahnen 2, dadurch gekennzeichnet, dass die Bahnspannung der Papierbahn im digitalen Druckwerk von der Bahnspannung der Papierbahn in der Wellpappenanlage entkoppelt ist. Plant for the production of corrugated cardboard with an integrated digital printing unit 9 for printing smooth paper webs 2, characterized in that the web tension of the paper web is decoupled in the digital printing unit of the web tension of the paper web in the corrugator.

Um eine hohe Druckqualität erzielen zu können, ist es notwendig, auf der glatten Bahn zu drucken. Diese digitale Druckeinrichtung wird vorzugsweise zwischen dem Papierbahn-Abroller und einem Vorheizer eingesetzt. Der bevorzugte Einbauort ist nach dem Kaschierbahnabroller 21

Aufgabenstellungtask
Für den Herstellungsprozess von Wellpappe ist eine Bahnspannung erforderlich, damit die Papierbahnen innig mit dem Vorheizer verbunden ist und damit die notwendige Temperatur aufnehmen kann und auch ein gerader ebener Bogen hergestellt werden kann. Diese Bahnspannung wird zwischen dem Abroller und der Heizpartie mittels am Abroller befestigten Bremsen aufgebracht. Eine Bahnspannungsregelung ist aus der
Konstante Bahnspannungs-Einflussgrößen können einmal mit dem in der
Bahnspannungsschwankungen treten z.B. durch unrunde Papierrollen auf.Web tension fluctuations occur e.g. through non-circular paper rolls.
Beim Splice, dem Verbinden von einer leeren Rolle mit einer vollen Rolle, treten Bahnspannungsschwankungen auf.When Splice, connecting an empty role with a full role, occur web tension fluctuations.
Bahnspannungsschwankungen treten durch Beschleunigen oder Verzögern der Wellpappenanlage auf.Web tension fluctuations occur by accelerating or decelerating the corrugator.
Bahnspannungsschwankung treten durch Dehnen und Zusammenziehen vom Heizpartiegurt auf.Web tension variation occurs by stretching and contraction from the heated bed belt.
Durch diese im Prozess zur Herstellung von Wellpappe unweigerlich auftretenden Bahnspannungsschwankungen tritt bei dem digitalen Bedrucken einer Papierbahn ein enormer Ausschuss auf, da diese Schwankungen nicht ausgeregelt werden können, da sie kurzzeitig aber immer wiederkehrend auftreten.As a result of these web tension fluctuations, which inevitably occur in the process for the production of corrugated cardboard, an enormous amount of waste occurs in the digital printing of a paper web, since these fluctuations can not be compensated, since they occur repeatedly for a short time.
Die Erfindung hat sich die Aufgabe gestellt, eine digitale Druckeinrichtung in einer Wellpappenanlage so zu integrieren, dass Bahnspannungsschwankungen, die bei dem Prozess zur Herstellung von Wellpappe unweigerlich auftreten, keinen Einfluss auf die Druckqualität haben.The object of the invention has been found to integrate a digital printing device in a corrugated board so that web tension fluctuations that inevitably occur in the process of producing corrugated board, have no effect on the print quality.
Dies wird dadurch erreicht, dass vor und nach der digitalen Druckeinrichtung eine Einrichtung eingesetzt wird, welche die Bahnspannung zwischen der Wellpappenanlage und der Druckeinrichtung entkoppelt.This is achieved by the fact that before and after the digital printing device, a device is used which decouples the web tension between the corrugator and the printing device.
