(under the class definition) Coating apparatus combined with means acting on the surface of the work to be coated, which means affects the surface of the work so that it may better receive the coating.
(1) Note. Means which merely heats or cools the base to prepare it to receive the coating is excluded from this subclass and is found in subclasses 58+.
(2) Note. This subclass includes, for example, apparatus to wash, flux, clean, abrade and/or smooth the work surface of the base, preparatory to and combined with a coating operation. Where the apparatus applies a preliminary coating, permanent in nature, and then applies a second coating to this same base, such apparatus has been classified in the plural coating subclasses, for which see the notes to subclass 216.
