Abstract
Coating apparatus for a thin plastics web comprises a coating deposition station for applying a coating to the web by vapor deposition and a support for supporting the web at the coating deposition station. The apparatus includes a device for urging gas into the region where the thin plastics web converges with the support to improve the thermal coupling between the web and the support and also to reduce the coefficient of friction between the web and support. The gas enables the coating to be applied by vapor deposition at coating speeds of up to 90 meters per minute without deformation of the thin plastics web.
