ABSTRACT:
The invention relates to a sleeve separator for a lead plate (2) of a lead-acid accumulator. The sleeve separator surrounds the front and rear sides and lower and bottom edges of said lead plate. The invention is characterised in that the separator material (6) on the top edge of the lead plate (2) and the sleeve is folded away from the lead plate on one side approximately at right angles, so that it projects sideways; in that the separator material (8) on the other, opposite sleeve side is also folded over the upper edge of the lead plate at right angles and also projects sideways from the side of the sleeve; and in that the two separator sections which project sideways at approximate right angles from the side of the sleeve and which are superimposed, are interconnected by a joint (7).
