Coater and a method for coating a substrate

摘要

A coater and method allow for an essentially dry coating process. In this process, a coating is continually applied to a casting drum. This casting drum will rotate to move the coating passed infrared drying units. The exterior face of the casting drum is cooled. The temperature of the coating will rise except at an area adjacent the casting drum. This will reduce the water concentration of the coating except at the area adjacent the casting drum. This arrangement prevents the coating from bonding to the casting drum. Therefore, the coating can easily be removed from the casting drum and applied to a final substrate.
