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&#xb0; C., preferably about 160 to 300&#xb0; C., and more preferably about 180 to 210&#xb0; C., eliminates sticking of the paste on the pasted metal mesh strip to the cutting devices and obviates the need for the paper barriers.

Paper elimination in the production of battery plates

An apparatus for gripping, guiding and transporting opposite longitudinal side edges of slit, deformable strip for forming expanded mesh sheet. One chain of each of two pairs of opposed endless chains has a longitudinal recess adjacent a longitudinal planar side edge of the strip for receiving the planar edge of the strip therein and the opposed chain of each of said pairs has a plurality of equispaced sharp projections for penetrating the longitudinal planar side edge of the strip whereby the said edge is effectively gripped between the opposed chains during expansion.
