(US4982482-A)      The manufacture of lead-acid battries involves providing a battery grid and pasting the grid with a battery paste such that a profiled and tapered battery plate is formed.    This battery plate is wrapped onto a coil and cured in curing apparatus. A battery element is formed using coils of the finished plate stock, separator material, and winged end plate.    After this, several battery elements are then placed into a battery contained.    USE/ADVANTAGE -   For automotive starting traction, industrial, and small sealed lead-acvid battery applications. More efficient, economical and automated method.    (29pp )    (US4998340-A)      A process for producing a battery element having at least one positive battery plate, at least one negative battery plate, and at least one interposed separator for a lead acid battery comprises the steps of providing an elementiser and feeding predetermined lengths of material from coils of positive battery plate stock, negative battery plate stock, and separator stock to the elementiser with the separator stock being interposed between adjacent stocks of negative battery plate and positive battery plate. The materials are indexed to establish adjacent coextensive portions of the materials, and the portions of the materials are cut to establish the battery element having individual negative and positive battery plates with interposed separators. The separator stock is fed such that the leading edge of the separator stock projects beyond the leading edges of the positive and negative battery plate stock.    ADVANTAGE -   Efficient, economical and highly automated. (29pp)    (US5044067-A)      The apparatus for fabricating a battery element has a device means for supplying positive battery plate stock, negative battery plate stock and separator stock. An index advances the positive battery plate stock. The negative battery plate stock and the separator stock are index to a set position with the separator stock interposed between adjacent stocks of negative battery plate and positive battery plate. A cutting device simultaneously severs adjacent portions of the positive battery plate stock. The negative battery plate stock and the separator stock create positive battery plates, negative battery plates and separators.    USE -   For lead acid battery. (28pp)    (US5079111-A)      A battery grid is passed with a battery paste so that a profiled and tapered battery plate is formed. This plate is wrapped onto a coil and cured in curing apparatus. A battery element is formed using coils of the finished plate stock, separator material, and winged end plate. After this, several battery elements are then placed into a battery container. The battery paste layer having a profiled surface, has at least one groove which is disposed at an angle of greater than about 45 deg. and less than 90 deg.C relative to the border strip portion on either side of a plane perpendicular to the strip portion. The profiled surface has a region of reduced width which is oriented parallel to the border strip portion and which meets at least some of the grooves.    ADVANTAGE -   Enables prodn. of lightweight and higher quality lead-acid battery.
