Andritz, Graz, Austria, has been awarded an order from Consorzio Cartiere, Tivoli, Italy, to upgrade a board machine and related stock preparation line at its mill in Tivoli. After startup, which is scheduled for the beginning of 2018, the capacity of the board machine will be increased from 78,000 metric tpy to more than 100,000 metric tpy.

The paper machine has a design speed of 1,000 m/min. and produces fluting, testliner, corrugated medium, and imitation-kraft papers, with a basis weight range of 90-170 gsm. The raw material is 100% wastepaper.

• Upgrade of the stock preparation line and approach flow system
• Upgrade of the board machine including a PrimeFlow SW headbox with dilution control for the bottom layer, rebuild of the top and fourdrinier wires and press sections with a PrimePress X shoe press
• Rebuild of the pre-dryer and after-dryer sections to adjust drying capacity to the new production targets
• New ropeless tail threading system
