Customer: Metsä Board
Description: Valmet will supply new reel and winding technology and surrounding equipment for Metsä Board Kyro mill in Finland. In the rebuild, new reel and winder with an automatic transfer rail connection will be installed to modernize the board machine KK 1.
Details: Valmet’s delivery will include two Valmet Broke Pulpers and an OptiReel Linear with center drives to minimize caliber loss. The reel is followed by automatic transfer rails and an OptiCart Stream parent roll cart with integrated loading. The new high-capacity OptiWin Drum two-drum winder will be equipped with a Dual Unwind two-unwind system.
