Abstract

帯状の芯材（１）をその長手方向に走行させつつその両面に電極合剤ペースト（５）を塗布し、電極合剤ペースト（５）が塗布された芯材（１）を一対の掻き落し治具（１６ａ、１６ｂ）間の隙間に通して電極合剤ペースト（５）の塗布厚を調整し、かつ掻き落し治具（１６ａ、１６ｂ）に設けたチップ（１８）にて電極合剤ペースト（５）を掻き落して所要幅の合剤塗布部を形成するとともに、チップ（１８）の芯材走行方向上手側に形成した凹溝（１９）を通してチップ（１８）で掻き落とした電極合剤ペースト（５）を還流させ、合剤塗布部の両側端部での塗布厚の増大化現象の発生を抑制するようにしたことにより、合剤塗布部の両側端部での塗布厚の増大化現象の発生を抑制し、合剤塗布シートの変形などの工程不良の発生を回避できる電極合剤ペーストの塗布方法を実現する。
