。 A bucking roll that supports the running base paper, a liquid supply nozzle that sprays the coating agent onto the outer surface of the base paper, and the excess of the sprayed coating agent is removed to form a uniform layer of coating agent on the surface of the base paper. In the blade coater, the lower lip of the liquid supply nozzle is made to protrude by a sufficient length (3 mm to 20 mm) than the upper lip, and the gap between the tip and the outer surface of the paper is defined as the nozzle exit slit. In addition to making the gap approximately the same as the thickness, the tip shape of the lower lip is rounded, its dimension is R≦15 mm or R≦20C (C: exit slit thickness), and the corners of the rounded range are β≦
A coating liquid supply nozzle characterized by an angle of 90°.
