OptiFlo Gap headbox
The key elements of the OptiFlo Gap headbox are its redesigned headbox turbulence generator and slice channel. These allow a consistent and disturbance-free slice jet. The objective of the OptiFlo Gap headbox is to achieve optimal fiber suspension fluidization and to maintain optimal fluidization without disturbance across the forming section.

Conversion to new grade
The world is changing fast; the consumption of newsprint and printing/writing papers is decreasing. The consumption of containerboards or cartonboards are rapidly increasing due to the e-commerce. An old paper machine can be updated with a grade conversion rebuild to produce more profitable products like containerboards, cartonboards or special papers.

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.

Metal belt technology
Pressing with metal belt technology boosts production capacity by eliminating unsupported open draws. It also increases the dry content after the press by up to 6 % due to more effective water removal at the press nip and evaporation over the hot metal belt. Furthermore, it improves several end product qualities, such as strength and porosity.

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.
