ABSTRACT:
Apparatus for drying printed web material comprises a chamber housing a fan disposed within a casing, the casing having a fan inlet open to the interior of the chamber. An outlet duct is provided for discharging drying flow of air from the fan to outside the chamber. A heater is provided for heating said flow, and means are provided for directing the heated air on to the printed web. A collector hood is provided for collecting the solvent mixture resulting from the web-drying operation. First and second outlet ducts allow outflow of the collected solvent mixture from the collector hood, the first outlet duct being connected to the inlet of the fan by way of the chamber interior. A fresh air inlet duct is also connected to the chamber interior, and separate valves in the form of louvres are provided for controlling flow through the first and second outlet ducts as well as the fresh air inlet duct.
