Abstract
An apparatus for removing bubbles in paint comprises a sealed container having an upper section and a lower section divided by a plate having one or more slit-like through holes and a pressure reducing device connected to the lower section. A paint coating system includes the bubble removing apparatus, a tank for storing a new paint, a first pipe line to feed paint from the tank to the upper section of the sealed container, a curtain flow coater or a roll coater communicated with the lower section of the sealed container so as to receive paint without bubbles, and a vessel to collect paint which does not contribute to form a coating layer.
