Abstract
A method of uniformly or substantially uniformly heating at least one surface of a substrate, comprises the steps of supporting a substrate, generating a heated air flow, directing the heated air flow to heat a strip of a first surface of the substrate, and moving the flow path of the heated air in a direction transverse to the direction in which the heated air flow impinges on the substrate until the temperature of the whole or substantially the whole first surface of the substrate has been uniformly or substantially uniformly raised. Apparatus for performing this method is also disclosed.
