The extensive rebuild will increase production and improve overall efficiency. The rebuild scope includes modifications to the forming section to increase the capacity and performance of the paper machine. The press section will be completely renewed, including the installation of a Tandem NipcoFlex press that will significantly increase the dry content after the press and reduce specific steam consumption.

The transfer between press and dryer sections will be modified with state-of-the-art web transfer and tail threading technology to provide the best runnability for lightweight grades. In addition, smaller modifications and upgrades in the stock preparation and approach flow line are planned.
