ABSTRACT:
A machine and method are disclosed which provide an efficient means for coating the annular surfaces on a plurality of workpieces. The workpieces are moved relative to a gun which sprays a coating material. As each workpiece passes within the spray, the gun moves alternately back-and-forth such that the center of the spray follows the curvature of the annular surface. Simultaneously, the workpiece rotates so that the entire surface is coated. The machine is provided with a camming mechanism for moving the gun, one motor for driving the camming mechanism, another motor for rotating the workpieces, and a series of belt and chain drives for synchronizing the motion of the gun with the movement of the workpieces.
