ABSTRACT:
A rectangular grid for supporting the active mass of a plate for an electric battery is formed by slitting a metal sheet to produce mutually staggered tiers of cuts, adjacent tiers being separated by distances substantially less than the sheet thickness. Upon a subsequent stretching of the slitted sheet to expand the cuts into generally rhomboidal meshes, the webs bounding these cells are twisted whereby the nodes connecting them, which are formed by the unslitted parts of the several tiers, are tilted onto their sides; with proper dimensioning, the flanks of the tilted nodes are substantially coplanar with the faces of two border strips which extend along the major sides of the rectangle and are formed integral with the grid from unslitted sheet portions. One of these border strips is integral with a terminal tab of reduced thickness extending over slightly less than half the length of that strip.
