ABSTRACT:
Apparatus for applying powdered coating to a workpiece--particularly to electric motor armatures and stators--including features relating to handling and masking of workpieces before, during and after coating, is provided. A first feature of the invention is the inclusion of all coating steps--e.g., coating, cleaning and precuring--as modules in a single treatment station on the production line. The treatment station can also be enclosed in a single housing to contain excess powder from both the coating and cleaning processes, so that a single powder recovery system can be used to recover the excess powder from both processes. The invention also includes a handling system for removing the workpiece from the production line, inserting it into the treatment station and moving it past the various modules in the treatment station, withdrawing it from the treatment station, and returning it to the armature production line. The handling system includes unique, self-locking gripping means, as well as automatic masking means, which are preferably integral with one another.
