OptiFlo Layering Gap headbox

The OptiFlo Layering Gap headbox can produce a two-ply sheet using one headbox and one gap forming unit. This headbox technology ensures excellent layer coverage without any mixing of individual layers, which is important for layered board products.

Gap with shoe blade

Novel gap forming technology OptiFormer Gap utilizes innovative shoe and blade technology to gain superior paper or board quality. The formation has beaten all other references.

Gap for board

OptiFormer Gap forming section with roll and blade technology is an optimal concept for lightweight recycled fiber-based fluting and linerboard for high-speed applications.

OptiCoat Roll metering roll coating

In OptiCoat Roll coating an excess amount of coating color is applied to the paper surface with the applicator roll. Final coat weight is then controlled by a metering blade or rod. The coating quality is very uniform and smooth.

OptiCoat Short Dwell coating

OptiCoat Short Dwell is a blade or rod coater with short dwell time application, especially well-suited for high-speed LWC coating. Short dwell time means that water penetration into base paper is minimized. This enables archieving low coat weights easily.

OptiDry Profile air dryers

Reduce energy consumption and maintenance work needed by replacing your old profiling infrared dryers with Valmet´s new innovation: a moisture profiling air dryer. It is the first air dryer with a moisture profiling function and is designed to replace profiling infrared dryers in a coating machine.

OptiDry Turn air dryers

OptiDry Turn air dryers are designed for drying the coated web and contactless turning at the same time. Aided by patented air dryer nozzles, the dryers achieve uniform evaporation with minimum energy consumption, high efficiency and excellent runnability. We can prove you get the best paper quality and lowest energy consumption with Valmet air dryers. OptiDry Turn dryers enable a shorter and compact layout with stable runnability and evaporation due to lack of free draws.

Multifourdrinier

Fourdrinier ensures high efficiency and output. The flexibility to make products across a broad range of grades is also often desired, and white lined chipboard, folding boxboard and coated SBS can all be produced on the same multi-Fourdrinier machine.

Curl control

OptiDry Curl, the new solution for curl control, is based on the impingement drying technology. Traditionally dryer groups with a double-felted configuration have been used for controlling the paper curl by adjusting different top/bottom dryer temperatures and affecting in this way drying on the two sides of the paper. Another traditionally used method is moisturizing (with water or steam), which also influences the curl of paper but at the same time increases paper moisture again.
