ABSTRACT:
A system for coating articles by the use of electrostatic attraction of ionized particles which are subsequently cured. The system includes a pair of carriers for jointly carrying each article through the system, from application of the particles to the article through curing of the particles on the article. Each carrier is capable of carrying the article independently of the other. After deposition of the particles on the article, the article and the carriers are conveyed through a cleaning station wherein one of the carriers is moved out of carrying engagement with the article and cleaned while the article supported by the other carrier. The other carrier is then moved out of supporting engagement with the article and cleaned while the article is supported by the first carrier. The system also includes a spray booth for depositing the particles on the article which limits the exposure of the carriers to the spray of particles and includes a removable replaceable insert to eliminate the need for cleaning the spray booth when there is a change in the nature of the particles being used, such as color.
