ABSTRACT:
Apparatus for enveloping battery plates within porous separators and for feeding a separator sheet to form a fold at the approximate midpoint of the separator, simultaneously positioning a battery plate with an edge adjacent to the fold line, passing the plate and separator through rollers to press the separator against both sides of the battery plate, and passing the folded separator and enclosed battery plate through an ultrasonic sealing unit for sealing opposite edges of the separator to form an envelope. The apparatus includes a separator sheet dispenser for dispensing individual separator sheets into an elongated passageway. The end of the passageway is blocked so that a separator reaching the stopping point buckles to form a fold at the approximate midpoint of the separator. A plate dispenser is provided for feeding a battery plate adjacent to the fold line of the separator and rollers are provided for receiving the plate and separator and compressing the sides of the separator against the opposite sides of the battery plate. The rollers feed the folded separator and battery plate through an ultrasonic sealing device for sealing opposed edges of the separator to form an envelope around the battery plate.
