Abstract
A spool for use with a swimming pool cover or with a shade cover. The spool has a roller assembly, and a cover (not shown) may be wound onto the roller assembly or unwound from the assembly. The roller assembly has a pre-tensioned rubber strip that when viewed in transverse cross-section is substantially rectangular in shape and two opposing sides of the rectangle are notched. This strip is tensioned when the cover is unwound from the spool and a locking mechanism retains the cover in a desired unwound position against the tension of the rubber strip.
