ABSTRACT:
The present invention resides in an envelope type separator for a storage battery and the manufacturing process thereof. The separator sheet is comprised of a first, microporous paper layer made of an inorganic powder material, a synthetic organic fiber material and an organic binder, and a second, coarse paper layer made of a synthetic organic fiber material and an organic binder, but no inorganic powder material, these layers being bound together by heating. The resultant separator sheet of combination paper type is then formed so that the mutually inward surfaces of the coarse paper layer are brought into contact with each other and are made to adhere to each other, preferably at the edges, by thermal fusion, so that the separator sheet is formed into the shape of an envelope process for making an envelope type separator sheet is also described.
