Abstract
Apparatus is disclosed for filling tubular battery plates with active material paste by extruding the paste into the tubes via feed tubes passing from an inlet end of an extrusion head to an outlet end arranged in a row. The plates are supported during the extrusion and the feed tubes proportioned so as to equalize the amount of paste fed into each individual tube.
Claims7
Apparatus for filling plates of the tubular type for lead acid electric storage batteries which includes:
- means for supporting tubes of a plate assembled on their spines,
- a pump and an extrusion head fluidically connected to said pump for extruding active material in the form of a paste, and
- a plurality of feed passages each having an inlet end connected to one of a plurality of ports distributed substantially uniformly around the longitudinal axis of the extrusion head to receive paste from it, and an outlet end communicating with one of a number of extrusion nozzles arranged in a straight row and registering one with each tube of the plate,
- the sizes of the nozzles being graduated so that those communicating with ports remote from the axis of the extrusion head are larger than those communicating with ports nearer to said axis, whereby the amount of paste issuing from each nozzle is substantially the same.
