Superior performance with Valmet headboxes

The headbox plays a key role in producing high-quality paper and board products. Designed to produce perfect visual appearence with good profiles accross the entire machine, Valmet headboxes deliver improved paper quality and increased machine productivity. Production and quality targets can be reached more quickly after start-up - and with fewer web breaks and less broke. This means high machine efficiency and a rapid return on your investment.

The keywords of a properly functioning headbox are uniformity and profiles. The hydraulic performance of the headbox mainly determines the properties of the paper. The headbox controls the web’s profiles and helps to establish paper properties such as formation.

Qualities of a great headbox include distributing stock uniformly across the forming section, without disturbances, and imparting sufficient turbulence to the flow to keep the fibers dispersed. Equally important factors are that the headbox is easy and simple to operate and remain clean during operation.

Headbox solution for your specific need

Valmet headbox family offers all application methods and all paper machine sizes available - Fourdrinier, layering Fourdrinier, Gap, and layering Gap headboxes as well as the new innovative aqua layering technology that makes it possible to produce a two-layer sheet with very good layer coverage using only one headbox and forming unit.

Valmet Paper Technology Center provides the world's most comprehensive offering of testing and piloting services to paper and board manufacturers worldwide. We offer the opportunity to experiment and develop paper and board products and processes without having to put your own production on hold. This is a very cost-efficient compared to expensive tests in your own production.

Our pilot facilities have the entire paper machine process covered providing customers with excellent service and reliable results to support investment decisions. Your R&D team is warmly welcome to join our experts to develop the optimal configuration to support your papermaking demands also in the future.

Learn more about OptiFlo headboxes

The OptiFlo headbox family introduces a new level of performance, with modular construction developed to meet the increasing productivity and quality requirements of high-quality paper and board machines. The OptiFlo headbox family combines proven technology with new ideas.

OptiFlo's advanced design simplifies later upgrades, making possible to handle changing production needs or introduce new control technology with minimal disruption to production. The headbox ensures optimum utilization, even if production or quality targets change.

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.

OptiFlo Layering Fourdrinier headbox

OptiFlo Layering Fourdrinier tackles the board makers’ challenges in combining lower basis weights, faster speeds and higher ash contents resulting from the increased use of recycled fiber. This provides excellent layer coverage, considerably lower residual variation in basis weight as well as an excellent formation.

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.

OptiFlo Layering Gap headbox

The two-layer OptiFlo Gap headbox can produce a two-ply sheet using a gap forming unit. In two-layer headbox applications, it is very important to guarantee layer coverage. All hydraulic components of the headbox have been designed to minimize slice jet and board sheet disturbances.

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.
