Abstract
A primary cell separator basket is formed from sheet material folded upon itself to form a basket bottom at the fold and bonded along margins in face to face contact extending from the fold. One or both sheet faces between the bonded margins are crowned outwardly to preform the basket and open its top. Basket preforms can be made in strips by longitudinally folding strip sheet material, crowning the material at intervals along the strip length and bonding the material in face to face relationship transverse of the strip length along the strip length in regions which fall between the crowns. Apparatus and methods of forming are disclosed for forming baskets and basket strips and for final forming and inserting baskets into primary cell subassemblies, including means to compress bonded margins toward each other to spread the crowned region, means to sever preformed baskets from strips of the preforms, means to insert a mandrel into a preform for forming a cylindrical basket, folding the bonded margins along the basket walls in a forming die, and advancing the mandrel mounted basket into a cell subassembly.
