Abstract
Abstract An automatic paint machine for painting cylindrically contoured objects. The paint machine includes a pair of housing members which are movable in a longitudinal direction for positionally mounting the cylindrical objects in a predetermined location. A cylindrical object to be painted is mounted in rotational displacement with respect to a multiplicity of rollers which extend from each of the housing members. Rotation of the rollers results in a corresponding counterrotation of the cylindrical object being painted. A series of spray nozzles are mounted on the machine to provide a spray of paint unto the surface of the object. A plurality of shield members are positioned adjacent a segmental portion of an outer surface of the object being painted. The shields intersect the path of paint being sprayed from particular spray nozzles to divide the object surface into zones and producing a sharp delineation of color between one zone and another. Additionally, the automatic paint machine includes an ejection mechanism for removing the cylindrical object from the machine subsequent to the painting operation being completed.
