CURL CONTROL

There are two types of curl: MD direction and CD direction Curl MD:

  • Usually mechanical in nature; must be dealt with as such

Curl CD:

  • Caused by a moisture unbalance between the two sides of the sheet
  • Traditionally corrected with dryer cylinders (upper-lower rows at different

steam pressures).

  • High thermal inertia/slow response system; besides, handicaps the actual

installed drying capacity of the PM.
