A spray coating application system for dispensing a liquid coating includes an elongated guide rail and a longitudinal slide plate slideably attached to the guide rail. The longitudinal slide plate is movable along a longitudinal axis of the guide rail between a first and second longitudinal positions. A transverse slide plate is attached to the longitudinal slide plate for concurrent movement therewith along the longitudinal axis of the guide rail. The transverse slide plate is moveable relative to the longitudinal slide plate in a transverse direction substantially perpendicular to the longitudinal axis of the guide rail. A spray nozzle is attached to the transverse slide plate for dispersing the liquid coating as a spray. A cam follower is attached to the transverse slide plate and engagable with a cam for moving the spray nozzle relative to the longitudinal slide plate between a first transverse position and a second transverse position.

A method of coating a substrate with a washcoat using a substrate coating apparatus is disclosed. The method comprises locating the substrate below the washcoat showerhead; bringing the partition ring into contact with the face of the substrate to thereby define a central region of the face of the substrate which lies within an interior of the partition ring and a peripheral region of the face of the substrate which lies outside the partition ring; conveying washcoat from the source of the washcoat, along the conduit and through the washcoat showerhead; discharging the washcoat out of the nozzle apertures towards the face of the substrate, the showerhead plate of the washcoat showerhead discharging washcoat onto both the central region and the peripheral region of the face of the substrate.

A mask and air pressure control system for use in coating deposition is disclosed. A method is provided for controlling liquid coating droplets during deposition onto a substrate by directing atomized liquid coating droplets in a flow path toward the substrate, and applying a vacuum or pressurized air from an air pressure control system to at least a portion of the atomized liquid coating droplets in the flow path. The air pressure control mask comprises an air pressure control fixture structured and arranged for connection to a source of vacuum or pressurized air, and a nozzle opening structured and arranged to at least partially surround a flow path of the liquid coating droplets and to selectively allow at least a portion of the liquid coating droplets to pass through the air pressure control mask, wherein the vacuum or pressurized air prevents at least a portion of oversprayed liquid coating droplets from being deposited on the substrate outside an intended edge of the coating.
