Abstract: A device for automatically spray coating objects which move along a path along a theoretical Y axis. A first rotatable disk is supported to rotate around its own first axis. The disk is in a plane that extends generally along a side of the path of the objects. The first disk is rotatable around an axis that extends across the path of the objects. A second disk is supported on the first disk and has a second rotary axis which is eccentric to and generally parallel to the first axis. A spray device includes a carrier supported on the second disk on a third rotary axis eccentric to the second rotary axis. Rotation of the first disk with respect to the support, or the second disk with respect to the first disk or the carrier with respect to the second disk orients the spray device. The spray device carrier may also be moveable along its own third axis to position the spray device.
