ABSTRACT:
An apparatus for pasting a battery collector assembly having a current collector and enlarged members having a top surface and a bottom surface and a thickness greater than the current collector is provided. The current collector has at least one predetermined area into which paste is to be filled. The apparatus comprises a paste-dispensing nozzle having an orifice located in a dispensing end of the nozzle. The nozzle is mounted to dispense paste in at least one paste area of the collector assembly. The nozzle dispensing end is adapted to size a first level of paste dispensed in the paste area on one side of the current collector, and a surface is provided opposite the dispensing end of the nozzle which is adapted to size a second level of paste dispensed in the paste area on the other side of the current collector. The clearance between the nozzle dispensing end and opposing sizing surface is adjusted such that paste is dispensed from the nozzle, flows into the paste area of the collector assembly, and is sized such that the first level is intermediate the stop surface of the enlarged members and the current collector and the second level is intermediate the current collector and the bottom surface of the enlarged members. Thus, the enlarged portions of the collector assembly are left substantially free of paste.
