Abstract
Equipment for surface treatment of articles, providing means for uniformly cleaning and completely burning off undesirable coatings formed on elements supporting the articles subjected to treatment. The equipment includes metallic elements for supporting the articles subjected to treatment, heating filaments placed inside each of the metallic elements, and a conveyor for moving the supporting elements through treatment and cleaning stations. The heating filaments, each of which is separated from each of the metallic supporting elements by an insulating layer, form parts of electrical circuits for heating the supporting elements, and burning off therefrom any coating material that adhered thereto at the treatment station.
