Supplier: Valmet
Description: Valmet will supply a forming section rebuild introducing a novel Sleeve Roll technology. The rebuild of the paper machine PM 3 targets production increase and improved end-product quality.
Details: The delivery for PM 3 will include modifications to forming section. The existing fourdrinier forming section will be rebuilt into OptiFormer Hybrid by adding a top forming unit that utilizes a novel and innovative Sleeve Roll technology. Sleeve Roll is a specially designed roll, which has a sleeve-like outer layer where dewatering pressure is created with a shoe. Because of Sleeve Roll, the top forming unit is vacuumless. This makes the technology especially suited for rebuilds as it enables unrivalled dewatering capacity and energy savings. All the rebuilt machinery will be automated with Valmet DNA Machine Control System.
The 5,900 mm-wide (wire) PM 3 produces recycled fluting grades in the design speed of 1,300 m/min and a basis weight range of 90-120 gsm
Start-up: The start-up of the rebuilt machine is scheduled for 2020.
