ST Paper boosts capacity after investing in an Andritz-supplied PrimeLineTM tissue machine with shoe press

America’s ST Paper has invested in an Andritz-supplied PrimeLineTM W 2000 high-speed tissue machine at its plant in Duluth, Minnesota.  

Start-up is planned for the end of 2022 and the machine has a design speed of 2,000m/min and a working width of 5.65m. It will produce a range of bath, napkin and towel grades.  

The scope of supply includes the approach flow equipment with double dilution capability for excellent fibre preparation, a fully cantilevered PrimePress XT Evo shoe press for gentle dewatering, a 16 ft. PrimeDry Steel Yankee with head insulation, steam and condensate systems, a high-performance Yankee hood and process air systems for energy-efficient drying.  

ST Paper acquired Verso Corporation’s idled Duluth mill in May 2021 with the intention to converting the mill’s production from specialty paper grades to tissue.  

The company has already converted two fine paper machines into tissue machines at its Franklin, Virginia facility.
