IntelliReel
The IntelliReel structure enables easy control over the reeling process. It lets to wind a paper precisely, repeatably, efficiently and safely. A uniform parent roll is obtained and ready for converting operations by the end of reeling process. IntelliReel benefits include: controlled nip throughout winding process, minimized winding defects and sheet losses, easy process control, safe and minimized maintenance and it can be a tailor made solution. In the optimum parent roll structure building the purpose of nip relieving is to reduce the excessive weight of the spool and thus control the nip load between the spool and reel drum.

Increase 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.
