Valmet will supply a high-capacity OptiWin Pro winder to Norske Skog’s Golbey mill in France. The main target of Norske Skog Golbey is to have one winder to handle the 550,000-tonne capacity of the converted high-speed and high-capacity paper machine PM 1, following the paper machine conversion from production of newsprint to production of recycled containerboard. The start-up of the winder is scheduled for 2023.The value of the order will not be disclosed. The value of an order of this type is typically around Euro 10-20 million.
Valmet’s delivery will include an OptiWin Pro high-capacity and high-speed pro winder with transfer rails and broke collection. To meet the high-capacity targets reliably with only one winder, the winder is equipped with all the high-tech features available; Dual Unwind system will improve capacity with an exceptionally fast parent roll change, a fast grade change system including automatic slitter positioning and automatic set change, and a core handling system with core grooving. The winder will be delivered installed.
To support the winder operators with the new winder, a support package of 6 weeks will be included in the delivery. The process optimization and support conducted during those weeks will cover items around winder runnability, uptime, winder broke and roll quality.
The winder will handle parent rolls with a width of 8,870 mm at a design speed of 3,000 m/min and a daily design capacity of 1,820 tonnes. Golbey PM 1 will produce recycled fluting and testliner grades with a design basis weight from 70 to 135 g/m2.
