ABSTRACT:
A paper drying apparatus including a first rotatable drum, wherein the first rotatable drum has an inner perimeter and an outer perimeter and a second rotatable drum having an inner perimeter and an outer perimeter. A fabric sheet for carrying a paper web is provided, wherein the fabric sheet passes around the outer perimeter of the first rotatable drum and proceeds to next pass around the outer perimeter of the second rotatable drum. As the fabric sheet conveys the paper web around the first rotatable drum, a drying air is applied to the paper web in a direction from the inner perimeter of the first rotatable drum toward the outer perimeter of the first rotatable drum, further passing through the paper web. As the fabric sheet and paper web proceed around the second rotatable drum, a drying air is applied to the paper web in a direction from the outer perimeter of the second rotatable drum toward the inner perimeter of the second rotatable drum, further passing through the paper web in a similar direction.
