Andritz was awarded an order from Consorzio Cartiere in Tivoli, Italy, to upgrade the board machine and related stock preparation line at the mill in Tivoli. After start-up, which is scheduled for the beginning of 2018, the capacity of the board machine will be increased from 78,000 to over 100,000 t/a.

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% waste paper.

Andritz’s scope of supply comprises:

* 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

* New broke pulpers

* Engineering, supervision, commissioning, start-up, training, spare part packages

The Andritz design provides innovative, high dewatering performance for the production of corrugated base paper grades. With the upgrade, Consorzio Cartiere in Tivoli aims at a significant improvement of the paper quality, enhanced runnability and increased production.
