Реферат: 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 to a predetermined first level on one side of the current collector and a predetermined second level on the other side of the current collector to form a paste layer of predetermined thickness less than the thickness of the enlarged members. The apparatus comprises a reservoir for electrochemically active paste, a paste-dispensing nozzle having an orifice located in a dispensing end of the nozzle, and a feed conduit connecting the paste reservoir and dispensing nozzle and operable to supply paste to the dispensing nozzle. The nozzle is mounted to dispense paste in at least one more paste area of the collector assembly. A valve is provided which is operable to control the flow of paste from the nozzle such that paste is dispensed therefrom and flows into the paste area. The nozzle dispensing end is adapted to size the first level of paste dispensed in the paste area, and a surface is provided opposite the dispensing end of the nozzle which is adapted to size the second level of paste dispensed in the paste area. 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 top 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.
