Abstract

Es wird ein Verfahren zum Behandeln einer Materialbahn angegeben, die von einer Rolle (2) abgewickelt und durch mindestens einen Walzenspalt einer Walzenspaltanordnung (6, 7) geführt wird, und eine Vorrichtung zur Behandlung einer auf einer Rolle (2) aufgewickelten Materialbahn (3) mit einer Behandlungsstation (5), einer der Behandlungsstation vorgeschalteten Abwickelstation (11) und einem der Abwickelstation (11) vorgeschalteten Rollenmagazin (15), das mindestens einen Speicherplatz aufweist,It becomes a method of treating a web of material specified that unwound from a roll (2) and by at least one nip of a nip arrangement (6, 7) is guided, and a device for Treatment of a wound on a roll (2) Material web (3) with a treatment station (5), one unwinding station upstream of the treatment station (11) and one of the unwinding station (11) upstream Roller magazine (15), the at least one Has storage space,

Bei der Bearbeitung von Materialbahnrollen entstehen durch die Wartezeiten ungleichmäßige Temperatur- und/oder Feuchtigkeitsverteilungen in der Rolle, die zu einer Verungleichmäßigung des Bearbeitungsergebnisses in der Bearbeitungsstation führen. Dies soll mit der vorliegenden Erfindung geändert werden.When processing web rolls due to the waiting times uneven temperature and / or Moisture distributions in the role that too an uneven processing result in the processing station. This should be done with the present invention can be changed.

Hierzu wird die noch auf der Rolle (2) befindliche Warenbahn (3) vor dem Abwickeln für eine vorbestimmte Mindestzeitdauer einer vorbestimmten Umgebungsatmosphäre ausgesetzt. Der Speicherplatz (18) ist hierzu in einer Kammer (22) angeordnet ist, deren Atmosphäre auf eine vorgegebene Temperatur und/oder eine vorgegebene Feuchtigkeit einstellbar ist.

Figure 00000001
For this purpose, the web (3) still on the roll (2) is exposed to a predetermined ambient atmosphere for a predetermined minimum period of time before unwinding. For this purpose, the storage space (18) is arranged in a chamber (22), the atmosphere of which can be set to a predetermined temperature and / or a predetermined humidity.
