Abstract
A drum is provided on its surface with depressions corresponding to the portions of a web not to be coated and is partially enclosed by a chamber in which separating agent is evaporated. The depressions capture vapor as the drum is rotated, and the web is passed over the drum where it is not enclosed by the chamber. Separating agent condenses on selective of the web correspond to the depressions, and a functional coating is subsequently applied. Thereafter the functional coating is removed from the areas where the separating agent was applied.
