ABSTRACT:
A spirally wound element comprising opposite polarity plates and interleaved separator is described, for use in electrochemical cylindrically configured cells. The cell pack has a uniform predetermined cross section irrespective of variation in component thicknesses as long as such thicknesses are within specified tolerances. Dual head, belt-driven winder and method are also described for producing the spiral cell pack.
