A method for powder coating of articles with an organic polymeric material. Articles to be coated, preferably glass containers, are transported by a first conveying mechanism through a pre-heat oven wherein their temperature is raised to a level above ambient temperature. The preheated containers are then transferred to chucks of a second conveying mechanism which carry the containers through a powder spray apparatus wherein the organic polymeric material is applied to the container. The chucks of the second conveying mechanism are cool and any oversprayed material will not adhere thereto. After spraying, the containers are again heated to cure the sprayed-on powder coating to form a filmlike layer on the container. The containers are then cooled below the softening point of the organic polymeric material and released from the second conveying mechanism for further handling. |
