Abstract
A reel for magnetic recording tape having a hub with flange attachment areas and a pair of clear plastic flanges, each having contact surfaces complementary to the hub attachment areas, the contact surfaces each having a pair of radially spaced circumferential ridges which serve as energy directors to ultrasonically weld the flanges to the hub and which contain adhesive within the annular region between the ridges to secure the flanges to the hub and to prevent eventual contamination of the tape on the reel due to migration of the adhesive.
