Abstract
A belt conveyor with a surface layer transferred onto its article-carrying or other surface to impart certain effective properties to the surface. The belt conveyor comprises a conveyor belt driven by a belt drive along a belt-conveying path. A transfer element transfers a coating material to a belt surface along a section of the belt-conveying path. Metallic bearing surfaces in contact with the belt surface act as transfer elements from which an oxidizable metal is rubbed by the relative motion of the belt to form a high-friction metallic oxide layer on the belt surface. Another transfer element is realized by an applicator with a reservoir for storing a coating material. The applicator is positioned close to the belt surface to dispense a layer of coating material with properties that mask the inherent surface properties of the belt. In yet another version, the conveyed articles themselves serve as transfer elements.
