High efficiency and output across a broad range of grades
OptiFormer Multifourdrinier forming section
Valmet 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. With this flexibility, production can be targeted at the best market potential and the highest value.
Cost-effective design with two, three, four or five Fourdriniers
High drainage and production capacity
Wide basis weight range with good sheet formation
Tailored concept for best utilization of raw material
A Fourdrinier forming section delivers gentle dewatering and high strength yield. The length of the Fourdrinier forming table is optimized for furnish used. The concept is cost-effective and provides good product properties throughout its operating range.
Multilayer web enables optimized structure for each of the plies
Fourdrinier forming can involve 1 to 5 plies, enabling a wide basis weight range with good sheet formation. The heaviest ply is often equipped with an OptiFormer Hybrid top former unit. Advanced dilution basis weight profiling can also be used for efficient profile control with the heaviest ply.
Valmet’s extensive product range also provides rebuild solutions for traditional Fourdrinier formers to improve end-product quality and output, or to enter a new basis weight range or board grade.
