<p>A casing suitable for covering a substantially rectangular electrode for a diaphragm-type electrolytic cell comprises a closed end, an open end, and two closed sides, at least one of the closed sides having a tab adjacent to the open end. The casing is formed of a flexible material which is folded or sealed to provide a closed end and then sealed to form two closed sides. The seal along a major portion of the sides is substantially linear while the seal along the edge of the tab is angular to and contiguous with the linear seal. The tabs, which can be twisted or turned to provide a flat surface, permit the casing to be easily sealed along the top and bottom edges to provide separators for diaphragm-type electrolytic cells which are leak-proof and expand or contract during cell operation without detrimental mechanical stress.</p> |
