Abstract
A corrugated board system comprises a first and a second material supply device for a first or second material web, a corrugated board production device, and a web tension measuring regulating arrangement between the corrugated board production device and the first material supply device. The arrangement comprises a web tension measuring regulating device with a web tension measuring mechanism and a first web tension regulating mechanism, and at least a second web tension regulating mechanism. The web tension measuring regulating device is arranged between the second web tension regulating mechanism and the corrugated board production device. The arrangement furthermore has an information processing unit, which receives web tension information from the web tension measuring mechanism and is configured so that to change the web tension up to a first web tension limit value, it sends web tension regulating signals to the first web tension regulating mechanism and to change the web tension beyond the first web tension limit value, it sends web tension regulating signals to the second web tension regulating mechanism.
