Abstract

803,488. Making battery plates; extruding. CROMPTON PARKINSON, Ltd. March 6, 1957 [Feb. 7, 1956], No. 3834/56. Classes 83 (2) and 83 (4). In a method of forming a plate for a lead-acid secondary cell or battery, a supporting grid is prepared by punching holes in an extruded sheet of lead or lead alloy foil. Lead or lead alloy is extruded by a press 1 having a ram 2, to form a tube 4 which is split continuously by a blade 5 and flattened by rollers 6. The flat sheet or foil so produced which may be ribbed or plain is perforated by punches 8, the holes so formed acting as a key for a paste subsequently applied at 9. Finally the pasted sheet or foil is cut into individual plates 12 by a blade 11. Alternatively flat lead sheet or foil, either ribbed or plain may be directly extruded from a press prior to the punching operation. Further, two flat sheets so extruded may be dealt with simultaneously. When cylindrical battery elements are required two continuous pasted strips with separators between are rolled up to form the element.
