High capacity and efficiency at the lowest possible cost

Rebuilding for production capacity increase

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.

Every board or paper machine has the potential to improve. When you have identified the need, it is only a matter of finding the perfect solution. Factors that might be restricting the production are for example:

  • Bottlenecks

  • Too many web breaks

  • Long web break times

  • Low machine speeds

  • Poor runnability
