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.

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.

High efficiency drying

OptiDry Twin impingement dryer represent high technology drying, enabling up to 30 % fewer drying cylinders (and thus a shorter paper machine and machine room) and optimized runnability due to higher dry content before cylinder drying. It also provides tools for increasing sheet bulk.

Coater blades

Coater blades play an important role in the paper or board making process. They hugely affect efficiency, both materials and time, and have a major impact on final product quality. In blade coating, paper quality variations and rapid wearing of coater blades inevitably result in production losses and higher blade costs. The Valmet Coater Blade family consists of four carbide blades which leave a uniform layer of coating color on paper or board surface, thus creating an excellent finish for desired coat weight. In addition to having a major impact on end-product quality, blades also improve production efficiency which in turn leads to more saleable production.
