Abstract
A cleaning device for cleaning a slit-like nozzle having an opening of a predetermined breadth for discharging liquid paint, with uniformity and with a small amount of cleaning liquid, wherein under a condition that a nozzle N is mounted on receiver plates 4, 4, a substantially air-tight space is formed, and a gas supply conduit is opened at one end of a cleaning portion 2 in the direction of the breadth of the nozzle, and an exhaust conduit 7 is opened at the other end thereof, being disposed in a vicinity of the gas supply conduit, so as to supply the cleaning liquid into the air-tight space. Then, since the air inside of the air-tight space is extracted from the exhaust conduit 7, the gas supplied from the one end flows towards the exhaust conduit 7 at the other end. The cleaning liquid contacts with the surface of the nozzle so as to dissolve and wash away any liquid paint adhering thereon.
