する。The present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view showing an outline of a doctor blade according to an embodiment of the present invention. First, the tank 1 is placed in close contact with the carrier film 3. The tank 1 is configured such that both upper and lower sides are open, and the first blade 4 which is the right side wall among the four side wall four sides is arranged with the blade facing downward. Next, the second blade 5 having a through hole 5b in the vicinity of the upper part thereof is disposed with the blade facing the carrier film 3 with a space of about 20 mm inside the first blade 4. Further, a third blade 6 is arranged between the first blade 4 and the second blade 5. The first blade 4, the second blade 5 and the third blade 6 are independently provided with long grooves 4c, 5c and 6c on both side walls of the doctor blade as shown in FIG. , 6d to the desired height.

Next, the first blade 4, the second blade 5 and the third blade 6 are moved up and down to move the first blade 4 and the second blade 5 from the upper surface of the carrier film 3.
And the gaps H 1 , H 2 , and H 3 to the blades (4a, 5a, 6a) of the third blade 6 are set. At this time, H 2 >
It is determined that H 1 > H 3 , but the upper end of the third blade 6 is set to be lower than the lower end of the through hole 5 b of the second blade 5.

When the carrier film 3 is transferred to the right as shown by the arrow,
The coating liquid 2 is extruded from the gap H 1 of the first blade 4 and comes out as a coating 7. At this time, a clearance of H 2 second blade 5 the gap H 1 of the first blade 4 H 2> H
Since it is set to 1 , the flow rate from the gap between the second blades 5 is larger than the flow rate from the gap between the first blades 4, and the surplus amount is larger than that between the second blades 5 and the first blades 4. Is stored in the space between the through holes 5b of the second blade 5
To reflux into the tank.

できる。従って均一の塗膜を形成できる効果がある。As described above, when the doctor blade of the present invention is used, since the third blade 6 is installed,
Even if the slurry flow is unstable between the third blade 6 and the second blade 5 in the tank, the liquid level is kept constant between the first blade 4 and the third blade 6, and Since the flow is stable, the thickness of the coating film does not fluctuate and can be supplied uniformly. Therefore, there is an effect that a uniform coating film can be formed.
