Abstract
Invented techniques and associated mechanisms are described for eliminating bi-directional flexure properties of coupled buoyant-slats forming a pool cover while simultaneously increasing the buoyancy of a leading or front portion of the cover and for assuring that the spiraling layers of wound-up layers of a buoyant pool cover are, and remain tightly wound around a submerged, rotatable cover drum at all times.
