Metso 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.
A Fourdrinier forming section delivers gentle dewatering and high strength yield. The length of the Fourdrinier forming table is optimized for the furnish used. The concept is cost-effective and provides good product properties throughout its operating range.
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 a ValFormer top former unit. Advanced dilution basis weight profiling can also be used for efficient profile control with the heaviest ply.
Metso’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.
