Increase production capacity

There are several ways to increase the production of a paper or board making line. The paper machine's efficiency can be improved for example by decreasing the number of breaks and shortening the break time. Drying capacity can be found to be a bottleneck. Drying capacity can be increased by solutions that maximize drying efficiency with minimum energy consumption. Machine speed can be limiting production, too.
