Valmet will supply a new winder for Shandong Chenming Paper Ltd at its Zhanjiang site in Guangdong province, China. The board machine BM 4 producing folding box board (FBB) will be equipped with a new solution to increase winding capacity. Start-up is scheduled for 2018.
Valmet’s delivery for BM 4 includes a high-capacity OptiWin Drum which is easy to operate, has excellent web separation and its set changes are reliable and fast.
“The high-capacity winder with the latest two-drum technologies is designed for the widest and fastest paper and board machines. This is the third winder with same modern sub-floor concept for Shandong Chenming. The customer has been very happy with the previous two. In this model, the winding drums are located below floor level and special attention has been paid to the dynamical behaviour of the winder ensuring excellent runnability,” comments Senior Technology Manager Jaakko Haapanen from Valmet.
