<P>PROBLEM TO BE SOLVED: To provide a coating method of an electrode mix paste for avoiding a decrease in coating dimension precision also in the case of a high-viscosity electrode mix paste in a method for coating a core with the electrode mix paste in a roll dipped into the electrode mix paste. <P>SOLUTION: In the coating method, a strip of core 1 made of a hole metal sheet is allowed to run in the longitudinal direction for feeding, the core 1 is wound around one portion of the outer periphery of the roll 8 dipped into the electrode mix paste 6, both the surfaces of the core 1 are coated with the electrode mix paste 6 by running due to the rotation of the roll 8, the coating thickness of the electrode mix paste 6 is adjusted, and the coated electrode mix paste 6 is dried. In the coating method, a groove 16 is formed on the outer-periphery surface of the roll 8 along a rotational direction, and the electrode mix paste 6 entering between the outer periphery of the roll 8 and the core 1 is discharged smoothly, thus suppressing the meandering of the core 1 and avoiding a decrease in the coating dimension precision. <P>COPYRIGHT: (C)2007,JPO&INPIT |
