ABSTRACT:
Apparatus for drying a web and modifying the moisture profile of the web includes a housing within which is disposed a through air dryer roll supporting a web. A fan located at an end of the roll causes flow of air through the web while the web is on the roll and through openings in the roll into the interior of the roll. The air then flows through a roll end and into the interior of the housing externally of the roll for recirculation back into the roll interior through the web and through the openings in the roll. Heaters heat the flowing air and are used to modify the moisture profile of the web. The apparatus is very compact.
