Abstract: An apparatus for processing a fibrous material batt like lint cotton to increase the moisture content of the material and to compress the batt of humidified fibers to increase the batt density. A stream of warm humid air is passed through the moving batt of fiber that is constrained between a rotatable hollow cylinder and a stationary perforated screen. The air passing through the batt of figure removes debris from the batt and carries the debris to an associated plenum. The batt is doffed off the rotatable cylinder by a roller that serves to both doff and compress the batt. A roller doffs the fiber batt from the rotatable cylinder and doffs and compresses the batt against a compression roller.
