えたことを特徴とするカーテンコータ。 Above the web 1 which is continuously moving in the horizontal direction, there is provided a liquid supply header 3 capable of causing the paint 2 to continuously flow downward in the vertical direction as a curtain-like liquid film 8 extending in the width direction of the web 1. A return pan 7 having an open top and receiving the curtain-like liquid film 8 is provided below, and the return pan 7 and the vessel 12 of the defoaming/deaerator 11 are connected to a paint having a first circulation pump 23 and a stop valve 25. The vessel 12 of the defoaming and degassing device 11 and the liquid supply header 3 are connected via the recovery pipe 26, and
It is connected via a paint supply pipe 32 having a circulation pump 31, and when the liquid level 18 in the vessel 12 rises to near the top of the vessel 12, a liquid level rise signal 1 is generated.
9 and a lower liquid level detector 22 that can output a liquid level drop signal 21 when the liquid level 18 in the vessel 12 drops to near the bottom of the vessel 12. installed in the air device 11,
A pump stop signal 28 that stops the first circulation pump 23 and a valve close signal 2 that closes the stop valve 25 based on the liquid level rise signal 19.
a controller 30 that outputs the signal 9, and the liquid level lowering signal 2.
1. A curtain coater comprising: a controller 34 that outputs a pump stop signal 33 to stop a second circulation pump 31 based on No. 1.
