Dryer Felt Design

Online Course Description:
On conventional paper and board machines, the energy required to dry the sheet to the desired moisture target at the reel is supplied by a series of rotating steam-heated dryer cylinders or cans that are grouped together into drive sections. Each drive section is equipped with one or two dryer felts to hold the sheet tightly against the heated dryer cans. This improves heat transfer to maximize drying, and also helps control cross-machine direction shrinkage and other sheet distortions. On many machines, dryer felts also drive some of the cans. This course covers the design and construction of dryer felts.
