(under the class definition) Coating apparatus combined with means to rotate the base at such speed that centrifugal force affects the coating.
(1) Note. The patents are placed in this and the indented subclasses on the bases of disclosure, i.e., if the rotating device functions as a centrifuge the patents are here classified. For work rotating devices combined with a coating apparatus which do not have a centrifuging function, see subclass 416 and the notes thereto.
(2) Note. The centrifuging may be for the purpose of distributing the coating on the article or for removing excess coating material from the article.
