A method of producing electrodes for lead acid storage batteries includes expanding a strip of lead or lead alloy to leave an unexpanded central land 14 and an unexpanded selvedge 12 on each edge of the strip. One or more lozenges of metal are sequentially removed from the land leaving holes 30 and 32 and simultaneously one or more portions of metal are removed from each selvedge leaving projecting portions 38. The strip is then separated into battery electrodes each of which has two or more feet constituted by the projecting portions 38. The invention also embraces an apparatus for carrying out the method. <IMAGE> |
