Stora Enso Anjala PM 2 has ordered EV EasyOne™ runnability components and services to improve runnability at the 1st and 2nd drying sections.

Also the first foreign paper mills have ordered EV EasyOne™ technology and many customers worldwide are very interested of the concept.

EV EasyOne optimizes the first single felted drying groups

Does your web run easily at the beginning of your drying section, at the first single felted groups?
Do you have sheet flutter and paper defects?
Does tail threading take too much time?

Especially in high-speed paper machines, the first single felted drying groups are very sensitive to run. Without support on web release between upper cylinder and vacuum roll the wet web tends to follow the upper cylinder, resulting in breaks and paper defects.

EV EasyOne™ optimizes the web release between upper cylinder and vacuum roll. It eliminates runnability problems that are caused when the sensitive wet web tends to follow the upper cylinder surface.

Traditionally, draw difference between press and drying section has been a tool to control runnability but this often causes problems in paper quality. With the EV EasyOne it is possible to improve the web release effectively with a special high vacuum area. This optimizes both drying section runnability and draws to improve paper quality.

EV EasyOne technology includes a special high vacuum area. This prevents web from following the upper cylinder and resulting in breaks and paper defects.

EV EasyOne technology is typically combined with the EV EasyGo concept combining web stabiling and vacuum roll technologies.

EV EasyOne ensures:

  • Excellent runnability of the first single felted drying groups
  • Eliminates sheet flutter and paper defects
  • Additional PM speed
  • More tolerance to process fluctuations
  • Reduction of raw material costs
