The rebuild will target sections from the former to the reel. The present Bel-Form former will be rebuilt into a modern DuoFormer D, allowing for maximum flexibility for optimum product quality. The press section will be a new Voith Centri NipcoFlex +3rd press for maximum press dryness and two-sidedness control. The main dryer section will also be rebuilt and will include DuoStablizers and VentiStablilizers for sheet stability.

The coater will be a Transfer Roll Coater from Voith-IHI. This coater will provide uniform coating application without the need for blade or rod metering, therefore, reducing operating costs. The calender will be completely rebuilt to modern technology. The reel will be a new TR125 reel for optimum reeling of the coated paper that will be produced.

Stock preparation equipment includes a three-stage MultiSorter broke screening system. The screens are equipped with 0.15 mm C-bar S baskets. The screens ensure that paper machine broke fed back to the blend chest is free of debris preventing sheet quality problems.

The supply also includes a new wet-end lubrication system and in addition, Voith Paper will provide erection supervision, start-up support and training services.

Design speed is 1100 mpm and start-up of the rebuilt 8360 mm wide machine is scheduled for May 2004.
