摘要

The cover has a tarpaulin that freely and completely rests on entire water surface (2), where an edge (5) of the tarpaulin follows and links with an inner edge (4) of a swimming pool. The tarpaulin is made of an open looped fabric, which is constituted of a material e.g. polypropylene, of density lower than that of water, where the tarpaulin edge has a seam (10) and a rectilinear bead (13), which is made of an expanded alveolar material or elastic material.
