Title:
ELECTRODE MIXTURE PASTE APPLYING METHOD AND APPLICATOR
Document Type and Number:
WIPO Patent Application WO2006115036
Kind Code:
B1
Abstract:
Electrode mixture paste (5) is applied to the opposite surfaces of a strip-form core material (1) while the core material is allowed to travel in its longitudinal direction, the paste (5)-applied core material (1) is passed through a gap between a pair of scraping jigs (16a, 16b) to regulate the coating thickness of the paste (5), and a chip (18) provided on each scraping jigs (16a, 16b) is used to scrape off the paste (5) to form a mixture coating with a specified width and paste (5) scraped off by the chip (18) is allowed to reflux through a groove (19) formed on the upstream side in the core material traveling direction of the chip (18) to thereby prevent the increasing phenomenon of coating thickness at opposite side ends of the mixture coating. Accordingly, an electrode mixture paste applying method is realized that can avoid a process trouble such as the deformation of a mixture coated sheet while preventing the increasing phenomenon of coating thickness at opposite side ends of the mixture coating.
