PURPOSE:To mass produce high performance separators having various thickness, by providing a layer formed with oxidation resistant resin aqueous solution, emulsion and more than two kinds of filler paste at the intermediate section of unwoven cloth and paper. CONSTITUTION:It is held by unwoven cloth and paper 1 while a layer formed with oxidation resistant resin aqueous solution, emulsion and more than two kinds of filler paste 2 is provided at the intermediate section. For example, mixture paste 2 of oxidation resistant resin and filler is mixed in mixing tank 3 and held between unwoven cloth, paper, etc. Then it is passed through drying/ hardening furnace 5 and cutter 6 to produce a lead storage battery separator. Since it has good coating performance, low electric resistance and high oxidation-resistant performance, separators having various thickness can be mass produced through same method by simply varying adhesion of paste. |
