Abstract: A battery electrode plate assembly and a production line and method of making, pasting, and applying separators to substrates of battery electrode plate assemblies. The production line includes, in an embodiment, a paster, a cutter, and a transfer mechanism. The paster is configured to apply a battery paste to a first side of an elongate web of a separator material. The cutter is downstream of the paster and is configured to sever the pasted web into a series of separate and individual separators with paste on their first side. And the transfer mechanism is configured to dispose an individual separator of the series on one of a series of substrates with the pasted first side of the separator facing the substrate on which it is disposed.

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.

Abstract: Disclosed herein is apparatus for cutting a strip of battery plate material into a plurality of battery plates, which strip of battery plate material includes a series of longitudinally evenly spaced apertures, and which apparatus comprises a plurality of support rollers rotatably mounted on a frame, an endless belt trained around the support rollers on an endless path, which belt includes an inner surface and an outer surface having thereon a plurality of longitudinally evenly spaced lugs adapted, when the strip is overlayed on the belt, to engage the strip apertures for advancing the strip in common with advancement of the belt, sprocket teeth on at least one of the support rollers and a plurality of apertures on the endless belt engaged by the sprocket teeth for advancing the belt along the endless path, a cutter roller mounted on the frame for rotation and for translation toward and away from the belt, which cutter roller has, on the periphery thereof, cutting knives for severing the strip into plates in

Abstract: An apparatus for separating paired battery plates into individual plates is disclosed. The disclosed apparatus has an improved alignment means which assures that the plates are separated about a fixed centerline. The apparatus is also suited for separating a plurality of stacked plates in a single cycle.

Abstract: Individual battery grids are effectively cut from a continuous sheet of expanded and pasted grid stock by the method and apparatus herein disclosed.

Abstract: A method and apparatus is described for feeding grid stock through a punch and die arrangement so that the spaced apart slots are equally spaced during the progression of the grid stock. The feed mechanism for strip stock comprises reciprocating punch means, die means associated with said reciprocating punch means to cooperate to punch out a group of spaced-apart slots in said strip stock, supporting means associated with said punch and die means to support said strip stock during its advance, a pair of members slidably mounted to said supporting means to operate on adjacent groups of spaced-apart slots in said strip stock to positively feed said stock away from said punch and die means, and means timed in respect to the reciprocation of said punch and die means and operative thereby, while said die means is raised from said punch means, to impart feeding movements to said feed stock.

Abstract: The subject invention is related to a cutting apparatus for forming individual battery grid structures from a sheet material having cut out portions thereon, said apparatus comprising spaced apart first and second rotatable means, a plurality of leading knives carried by said first means, a plurality of trailing knives carried by said second means, said knives arranged to cut transversely of said material forming shear lines from the edge of said sheet material to the cut out portions of said material, a plurality of blades carried by said first and second rotatable means for cutting longitudinally of said sheet material along a slit line between adjacent cut out portions of said sheet material, said knives and blades being spaced about the periphery of said first and second rotatable means and arranged to cooperate to sectionalize and form thereby individual battery grid structures from said sheet material.

Abstract: A mechanism is provided in a battery grid casting machine for receiving grids one at a time from a grid trimming die and for arranging them in a horizontally stacked arrangement on a pair of pivoted rails. After a predetermined number of grids have accumulated on the rails, the rails are pivoted from a horizontal to a vertical position to deposit the grids as a vertical stack on an intermittently moving conveyor.

Abstract: Battery grid plate castings are trimmed in a two-step operation. Each plate moves flat along a horizontal or inclined path against a first stop bar. One of two trim blades on a reciprocating upper die block then shears flashing from the leading end of the plate during a downward stroke of the die. Then the stop bar raises during the upward stroke of the die, and the plate moves forwardly against a second stop. Upon the next downward die stroke the second trim blade shears flashing from the trailing edge of the plate. During the next upward stroke, the fully trimmed plate moves forwardly onto a stacking device. As the leading end of one plate is trimmed at the first trim station, the trailing end of a preceding plate is trimmed at the second trim station. The second stop is easily moved to different stop positions along the path of travel of the plates to change the distance between such stop and the second trim blade and thereby enable trimming plates of different lengths without changing dies.
