Coating articles with plastic powder - by feeding them through powder contained in a vibrating container

Small articles are pre-heated and fed into a vibrating container in which plastic powder is contained, the articles passing downwardly through the containers along a helical track in the container so that as the articles pass through the powder (which itself is vibrating) the powder adheres to the articles the base of the track is formed as a screen through which the powder can eventually pass out of the container for re-cycling. According to the improvement the helical track is divided into several separate helical tracks each consisting of approx. one turn. The base of each track is provided with projections which act on the articles to re-orientate them as they move around the track and cause them to turn around completely one or more times. Excess powder adhering to the articles is removed. Where the articles have depression the device ensures the depression surface is coated.
