摘要：
This disclosure relates to a structure used to prevent the buildup of high voltage static electric charge on the flanges or support hub of motion picture reels. A conductive coating is placed around the nonconductive areas of the connection between the flanges and ground potential so that the accumulation of discharge potentials is prevented.
