Abstract
A process for centrifugal coating of large-surface, arched elements, especially of cathode-ray-tube displays or screens, in which during the centrifugal coating, a disk matched to approximately the shape of the surface to be coated is rotated at a distance of 1 to 10 mm above the surface to be coated at approximately the centrifugal speed equidirectional with the surface to be coated.

A process for coating material on large-surface, arched objects by centrifugal coating, wherein during the centrifuging process, a disk matched to approximately the shape of the surface to be coated rotates with the arched objects at a distance of 1 to 10 mm above the surface to be coated at approximately the centrifugal speed equidirectional with the surface to be coated as the coating solution is applied.
A process for coating an arched surface of an object with a material comprising the steps of:
- retaining the object with a retainer;
- covering the arched surface with a shield spaced about 1 to 10 mm above the arched surface;
- rotating the retainer shield and object together while dispensing the coating solution through the opening into the space between the shield and the arched surface to centrifugally coat the arched surface with the solution.
