OptiFlo Fourdrinier headbox

The innovative design of OptiFlo Fourdrinier headbox provides the greatest floc breaking ability and flattest profiles available on the market. That ensures that the paper and board products you make is of optimal quality. All the features of the headbox have been carefully designed to increase machine productivity, while keeping daily operating costs in control.

OptiFormer 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.

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.

Aqua layering technology

This technology uses a thin water layer as a headbox wedge to stabilize layers while layers of stratified paper are being joined together. It prevents mixing of stock layers and also enables feeding of functional additives between the stock layers. Combine with OptiFlo Layering Fourdrinier and OptiFlo Layering Gap headboxes.

Forming

Solutions for gap forming, hybrid forming and Fourdrinier applications.

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.

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.
