  "abstract": "A method of making a lead-acid battery includes providing continuous lengths of end separator stock, positive plate stock, intermediate separator stock and negative plate stock with optional use of end separators. The separators, positive plates and negative plates are individually severed from the continuous length of stock and sequentially formed into an assembly. The assembly is introduced into a battery cell container. A plurality of assemblies may be established prior to introduction into the battery cell container. In a preferred embodiment, the assembly zone moves relative to the cutting stations for the respective continuous lengths of stock and facilitates sequential establishment of the assembly without intermediate storage of the individual separators and elements. The apparatus includes equipment for supplying continuous lengths of end separator stock, positive plate stock, intermediate separator stock and negative plate stock. An assembly zone is adapted to receive the individual separator end plates from which the assembly may be introduced into a battery cell container. In one embodiment, a separator and an associated positive or negative plate may be cut substantially simultaneously. In another embodiment, they are cut individually.",
  "claims": [
    "1. Apparatus for making a lead-acid battery comprising, means for supplying a continuous length of positive plate stock, means for supplying a continuous length of separate stock, means for supplying a continuous length of negative plate stock, means for severing individual separators and plates from said means for providing continuous lengths thereof, assembly means for sequentially receiving individual separators and plates and establishing an assembly thereof, and means for inserting the assembly of said separator and plates to a battery cell container.",
    "2. The apparatus of claim 1 including, means for providing an end separator from a continuous length of separator stock, said means for severing including means for severing said end separator, and said assembly means having means for adding at least one said end separator to said assembly.",
    "3. The apparatus of claim 1 including, said severing means including cutting means associated with each said means for providing continuous lengths.",
    "4. The apparatus of claim 1, including said assembly means being relatively moveable with respect to said severing means, whereby after severing each said separator or plate may be transported to said assembly means directly without intermediate storage.",
    "5. The apparatus of claim 4 including, means for transporting said assembly means in a path of generally linear movement with respect to stationary said severing means.",
    "6. The apparatus of claim 5 including, said battery cell container means being disposed adjacent to said assembly means.",
    "7. The apparatus of claim 6 including, said assembly means having a plurality of alignment means for securing said plates and separators in desired relative positions.",
    "8. The apparatus of claim 7 including, said alignment means including a plurality of generally spaced upwardly projecting retractable alignment pins."

  "description_excerpt": "This is a division, of application Ser. No. 07/464,104, filed Jan. 12, 1990, now U.S. Pat. No. 4,973,335.\n\n1. Field of Invention\n\nThis invention relates to an improved method for the assembly of lead-acid batteries and an apparatus related thereto. More specifically, the invention relates to a flexible, high speed method for the manufacture of lead-acid batteries in a wide variety of sizes and configurations from continuous lengths of battery plate stock.\n\n2. Description of the Prior Art\n\nConventional lead-acid storage batteries generally consist of a plurality of alternating flat pasted positive plates and flat pasted negative plates which are electrically insulated from one another by a porous separator material. The cell assembly so constituted is placed into a suitable container in which the positive and negative plates are brought into contact with a sulfuric acid electrolyte. In batteries containing free electrolyte, the cell assembly is generally fully immersed in the sulfuric acid. In batteries containing no free electrolyte, the sulfuric acid is fully absorbed in the plates and separator material.\n\nThe manufacture of storage batteries of the type described hereinabove, generally involves alternately stacking cured pasted positive plates and cured pasted negative plates to form a cell assembly in which each positive plate is separated from each negative plate by a porous separator material. The cell components are aligned such that all of the positive current collecting lugs are aligned with one another.",
