In the SymDry
concept, there is one single-tier section at the beginning and usually two or more two-tier sections at the end. The bottom rolls in the single-tier section are either dryer cylinders or grooved UnoRolls.
In the after dryer section, the curl can be adjusted by controlling the pressure of the top and bottom cylinders separately.
