OptiFlo Layering Gap headbox

High-performance layering gap headbox for demanding gap forming applications

The key elements of the OptiFlo Gap headbox are its completely redesigned headbox turbulence generator and a slice channel built using composite wedge technology. These innovations allow a consistent and disturbance-free slice jet. The key objectives of the OptiFlo Gap headbox are first to achieve optimal fiber suspension fluidization and then to maintain this optimal fluidization without disturbance across the forming section.

Experiences from several production machines show that homogenous slice jet quality yields excellent board properties. This gap forming headbox design maximizes the utilization of raw material strength potential, which enables the use of more cost-effective raw materials.

Cost efficient layering headbox concept

Having two separate headboxes is a much bigger investment compared to a layering headbox. But the cost savings do not come only from the initial headbox investment. There are possibilities for great operational cost savings as well. With two headboxes you have two wires running with all the water and chemicals. These require cleaning and changing wires, which take a lot of time. All of these create a higher operational cost compared to a layering headbox. So, it is not only about the initial headbox investment, but consider also the cost savings in energy, chemicals and consumables when comparing investing in a layering headbox versus several headboxes.
