Patent ID: 8119190

Claim:
An electrode mixture paste application method for applying an electrode mixture paste on a core material made of porous metal thin plate while traveling the core material, the method comprising: a first step of unwinding the core material wound in a coil shape; a second step of applying the electrode mixture paste onto the core material; a third step of adjusting an application amount of the electrode mixture paste; a fourth step of drying a paste-coated sheet with the electrode mixture paste applied to the both sides thereof; and a fifth step of winding the paste-coated sheet in a coil shape, wherein, in one of the second and third steps, a core material-exposed portion to which the electrode mixture paste is not applied is provided in both edge portions in a width direction of the core material, in the fourth step, a holding unit is provided in at least one position, the holding unit continuously holding the core material-exposed portion between a wheel type roller and a contact belt and changing a traveling direction of the paste-coated sheet, and in the fourth step, meandering motion control is enabled by changing an angle of the wheel type roller with respect to a traveling direction of the core material without changing an angle of the contact belt according to an amount of the meandering motion of the paste-coated sheet detected by a meandering motion detecting unit to control the traveling direction of the paste-coated sheet.
