Andritz Group to upgrade board machine at Italian paper mill

The paper company Corsorzio Cartiere, Tivoli, Italy, has announced plans to upgrade its board machine and related stock preparation line at its mill in Tivoli. The upgrade will be performed by the Austrian equipment company Andritz Group. The upgrade is expected to be completed by the beginning of 2018.

A release from Andritz Group states that the paper machine being installed has a design speed of 1,000 meters per minute and will produce fluting, testliner, corrugated medium and imitation kraft paper. Base weights for the finished product will range from 90-170 grams per square meter (gsm). The raw material to be used at the paper mill will be 100 percent recovered fibre.

After the upgrade is complete the machine will see its capacity increase from 78,000 tonnes per year to 100,000 tonnes per year.

The project will include the following:

• Upgrading the stock preparation line and approach flow system;

• upgrading 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;

• rebuilding the pre-dryer and after-dryer sections to adjust drying capacity to the new production targets;

• a new ropeless tail threading system;

• new broke pulpers; and

• engineering, supervision, commissioning, start-up, training and spare part packages.
