ELECTRODE MIXTURE PASTE APPLYING METHOD AND APPLICATOR

摘要

Electrode mixture paste (5) is applied to the opposite surfaces of a strip-form core material (1) of punched metal thin sheet while the core material is allowed to travel in its longitudinal direction, the paste (5)-applied opposite surfaces of the core material (1) are pressed alternately at least one time by pressing rollers (15a, 15b) one surface at a time, then the paste (5)-applied core material (1) is passed between a pair of scraping jigs (16a, 16b) having comb-tooth-shaped projections (17a or 17a, 17b) used to regulate the position of the core material (1) to thereby regulate the coating thickness of the paste (5), whereby it is possible to accurately regulate the coating thickness even when the intervals between the projections (17a, 17b) are made wide enough to permit the welded portions of the core material (1) to pass. Accordingly, an electrode mixture paste applying method is realized that can avoid a production trouble to be caused by the bite-in of welded portions even when a core material is continuously produced while being welded with a coating thickness regulated accurately.
