Abstract: A spraying arrangement having particular adaptability for use in combination with a conveyor installation characterized by conventional sprayer equipment for painting or coating production parts, where excess paint or coating material is deposited on a back up shield, the latter serving to overcome, or at least minimize, overspray.Particular importance of the arrangement lies in the fact that the load capabilities of the conveyor can be more fully utilized, i.e. the parts under process can be sprayed from opposite sides of the aforesaid shield, being mounted on the same conveyor hanger.The shield may be in the form of selectively movable porous material and, in the instance of electrostatic paint spraying, a grid, charged with the same electrical potential as the part, is disposed within passes of the shield for even more effective excess material collecting purposes.
