Every increase of 1% of the dryness of the output press paper can reduce the drying load of the dryer by 4%. Therefore, it can save energy and increase production;

Due to the huge consumption of workers and time for installing and changing the felts, seamed felt appeared. It’s more suitable for huge paper machines.
