Abstract

A curing chamber has entry and exit ports for passing articles to be cured therethrough. Air curtains are provided at the inlet and exit ports. Communicating means connect the air curtains to a source for maintaining a pressure equilibrium at the air curtains. Means from outside the air curtains supply a controlled heated moist vapor for providing predetermined moisture to the air curtains to thereby reduce the escape of volatile gases within the curing chamber.
