In a booth in which articles are carried along a pathway for treatment with sprayed material directed through nozzles or the like at the pathway, apparatus is provided for positively rotating the conveyed articles to assure uniform treatment on all sides thereof. Article supports are connected to the conveyer, each having a first portion carried by the conveyer and a second portion rotatable relative to the first portion for holding an article. A toothed member on the second portion is positively engaged by and driven by links of a link belt to rotate the second hanger portion and the article held thereon.
