“We have excellent relations with VPK Group from earlier projects, for example Blue Paper’s grade conversion rebuild in France. I felt we were able to adapt well to the customer’s needs in this project as well: as the machine in question is familiar to us, we were able to offer proven and reliable technical solutions that fulfilled the requirements cost-efficiently,” says Markus Laitila, Director, Large Projects, Valmet.
Valmet’s grade conversion delivery will include a new approach flow system, modifications to the headbox, a shoe and blade technology upgrade in the forming section, and a new OptiPress Center press section to improve drying and runnability. The drying section will be updated into OptiRun Hybrid. The delivery will also include an extensive air systems upgrade. The delivery will be complemented with improvements in the automation system, including machine control systems, sectional drive control systems, quality management systems, process control systems, and a paper machine clothing package. The machines and equipment included in Valmet’s delivery will be delivered installed.
The 9.55m-wide PM produces fluting and testliner grades with a basis weight range of 75–135 gsm. The design speed of the new parts will be 1,300 m/min with an annual capacity of 450,000 tonnes.
