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.
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.
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.
Pratt Industries started up their new PM 17 board machine in 2019 at Wapakoneta, Ohio. The start-up was a great success thanks to both extensive training and the unique opportunity to train their personnel on exactly the same type of OptiConcept M line at Pratt’s PM 16 machine in Valparaiso, Indiana.
Arkhangelsk Mill aims for competitive advantages after the rebuild of BM2. "We have a wide basis weight and end product format range for flexibility. We expect decreased costs and energy consumption: 15-20% heat savings, 8% electricity savings and 5% reduction in water consumption," says Alexander Tuvanof.
“There is an increasing demand for packaging board in India and board has an important role in replacing plastics. We needed a trustworthy equipment supplier and technology which can convert raw material to a high-quality board in a cost-efficient way", says Sanjay Singh, CEO of ITC Paperboards and Specialty Papers Division.
In 2015, Stora Enso converted their existing paper machine In Varkaus Mill to produce linerboard to better meet the market need for renewable packaging. PM 3 is almost like a new machine now; a combination of brand new and good, well maintained trusted technology.
