ABSTRACT:
An apparatus for spray marking lumber boards with paint at predetermined locations while they are being conveyed past the device for further processing. A tachometer and a photoelectric unit are employed for determining the location and speed of the board. A solenoid-operated paint sprayer is used to deliver the paint to the boards. Electronic control circuitry is provided to activate the paint sprayer and properly coordinate the operation of paint sprayer with the location and speed of the board so the board is marked at the desired locations.
