IR & COMBUSTION SPECIALISTS 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.
