ABSTRACT:
A novel apparatus for forming lead-acid storage battery plate envelopes from a continuous roll of heat sealable separator material is described comprising material feed means for supplying material from the roll for use in the envelope, draw means for drawing preselected lengths of separated material into a processing position, cut-off means for severing predetermined lengths of material at the processing position into envelope forming lengths, means for folding said envelope forming lengths around a plate into a folded configuration wherein overlapping edges of separator material protrude beyond at least one side edge of said plate and sealing means for heating edges of said material under pressure to seal said overlapping edges to form said battery plate envelope. The preferred embodiment apparatus of the present invention additionally comprises a creasing means for pre-creasing the separator material prior to folding, which creasing means additionally functions to clamp the separator material during the operation of the cut-off means. In the preferred embodiment, the creasing means, cut-off means and draw means all act upon separator material when it is disposed in a first separator feed plane. The folding means, sealing means and extractor means of the present invention generally act along a second plane which is transverse to, and preferably perpendicular to, the aforementioned separator feed plane.
