Patent ID: 8088444

Claim:
A method for applying an electrode mixture paste, comprising: an application step of applying an electrode mixture paste ( 5 ) on both sides of a strip of core material ( 1 ) made of porous metal sheet having a weld point with a doubled thickness as the core material runs along a lengthwise direction thereof; a uniformizing step of pressing the core material coated with the electrode mixture paste alternately from opposite sides once or more; and a coating thickness adjusting step of adjusting a coating thickness of the electrode mixture paste by passing the core material coated with the electrode mixture paste through a gap between a pair of scraper tools ( 16 a , 16 b ), a position of the core material being restricted using comb-shaped projections ( 17 a , 17 b ) provided to at least one of the scraper tools, wherein the gap between the pair of scraper tools is wider than a thickness at the weld point of the core material.
