OptiFlo 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 paper properties. This gap forming headbox design maximizes the utilization of raw material strength potential, which enables the use of more cost-effective raw materials.
The two-layer OptiFlo Gap headbox can produce a two-ply sheet using a gap forming unit. OptiFlo II and OptiFlo Pro headbox applications are available under the renewed name OptiFlo Gap headbox.
