  • Publication number: 20230173514
    Abstract: A spray coating apparatus that applies a coating material onto outer surfaces of glass objects includes a coating material source that includes a coating material. A spray nozzle assembly includes a spray nozzle fluidly connected to the coating material source. The spray nozzle is arranged and configured to direct the coating material in a first direction toward the glass object and provide an overspray amount of the coating material by the glass object such that the overspray amount bypasses a non-line of sight area of the glass object. A turn nozzle assembly includes a turn nozzle fluidly connected to a pressurized gas source. The turn nozzle is arranged and configured to direct pressurized gas in a second direction different than the first direction toward the non-line of sight area of the glass package to redirect the coating material onto the non-line of sight area.
