  • Paper elimination in the production of battery plates
    Patent number: 7007579
    Abstract: A method and apparatus for continuously producing pasted positive and negative electrode plates from pasted lead or lead alloy expanded, punched or cast metal mesh strip for use in lead-acid batteries without the use of paper barriers. The heating of cutting devices such as roll-mounted die-cutters to a predetermined temperature range of at least about 150° C., preferably about 160 to 300° C., and more preferably about 180 to 210° C., eliminates sticking of the paste on the pasted metal mesh strip to the cutting devices and obviates the need for the paper barriers.
    Type: Grant
