Apparatus for forming and inserting cell separator baskets
This patent describes an apparatus for manufacturing a primary cell separator basket preforms comprising folding means for a strip of separator sheet material. The strip has parallel longitudinal edges and is of a width at least twice the height of the separator basket. The folding means folding the strip longitudinally and parallel to the edges of the strip with the width of the narrowest side of the strip contiguous to the fold at least the height of the separator basket and the length of the strip and the fold greater than preform widths of length exceeding one half the perimeter of the separator basket. The folded strip having overlaying strip sides, the folding means including a folding mandrel normal to the path of the plane of the strip and has opposed longitudinal sides and guides closely spaced from the mandrel sides for confining the folded strip panels against the opposed longitudinal mandrel sides. First and second spaced strip clamps are mounted for joint reciprocal motion along the path of the folded strip and arranged to grip selectively the outer faces of the strip; reciprocal drive means for the first and second strip clamps; means to actuate the clamps to grip strip and to actuate the reciprocal drive while the clamps grip the strip; and joining means to join the overlaying sides of the folded strip at paired bond regions spaced apart generally one half the perimeter of the separator basket and extending continuously from the fold toward and normal to the longitudinal edges of the strip. The paired bonds are spaced along the strip to define preforms having basket bottoms at the fold. An open basket is top opposite the fold and closed basket sides between the paired bonds.
