Abstract 1. The method of making a cover for retaining active material on the respective rods of conductive material of a plural, parallel rod electrode for use in a storage battery having positive and negative electrodes and a liquid electrolyte comprising the steps of: (a) providing a plurality of like fibrous sleevings; (b) placing the sleevings under at least nominal tension on substantially flat mandrels; (c) alternating the sleeving covered mandrels with a electrolyte resistant synthetic resinous material in contact with the sleeving of the immediately adjacent mandrels, the material being substantially one half the width of the mandrels and transversely centered with respect thereto; (d) compressing the alternated sleeving covered mandrels and material while applying heat to secure adjacent ones of the sleevings to each other in the area of the resinous material by the impregnation of the sleevings with the material; (e) removing the mandrels from the secured sleevings; and (f) expanding the secured sleevings to form a plurality of tubes of substantially rectangular cross section, with the resinous material substantially coextensive with the width of the expanded electrode cover.
