发明名称 Swiveling banner-carrying apparatus
摘要 A banner-carrying apparatus which reduces the folding and winding up of the banner or flag about the banner-carrying pole by using a tubular sleeve coaxially, annularly and rotatively mounted about a flag pole shaft. Low friction bearing surfaces allow the sleeve to freely rotate unwinding, through the force of gravity, a flag which has been wound upon it. Specialized clamps provide adjustable and releasable securing of the flag to the sleeve.
