Following the successful rebuild and start-up of the wet section of the paper machine PM4 in 2010, international technology Group Andritz has received a follow-up order from Cartiere Modesto Cardella to rebuild PM3 in Lucca, Italy. Start-up is scheduled for the end of 2016.
The scope of supply comprises an Andritz PrimeFlow TW two-layer headbox with PrimeProfiler F dilution water control and PrimeForm TW gap former. The PM3 has a design speed of 1,200 m/min and produces fluting, testliner, and corrugated medium with a basis weight range of 80-150 gsm. The raw material is 100% waste paper.
The Andritz design provides innovative, high dewatering performance for the production of corrugated base paper grades with minimum two-sidedness, thus there is as little difference as possible between the surface quality of the wire side and the surface quality of the top side of the paper web. The driving factors for Cartiere Modesto Cardellaʼs rebuild are significant improvements in paper quality and runability.
