Preventing the curling tendency of paper

The CombiDuoRun drying concept dries the paper web on both sides, preventing the curling tendency of the paper.

The CombiDuoRun is a combination of single-tier dryer groups in the front and double-tier dryer groups in the rear of the dryer section. It is therefore possible to construct the dryer section more compactly with the same drying capacity. Depending on the paper grade, the CombiDuoRun allows reliable operating speeds of up to 1650 m/min.

The CombiDuoRun is used in the dryer section and enables paper webs to be dried more efficiently. For graphic papers, the CombiDuoRun is mainly used in the after-dryer section of wood-free paper grades.
