Abstract
Abstract A METALLIC TAPE, HAVING A RELEASE AGENT MATERIAL APPLIED SELECTIVELY IN AT LEAST ONE LONGITUDINAL STRIP ON ONE MAJOR SURFACE THEREOF, HAS A COATING OF ADHESIVE OVER THE STRIP AND BOTH MAJOR SURFACES. THE TAPE IS WRAPPED LONGITUDINALLY ABOUT A CABLE CORE, WITH THE ONE MAJOR SURFACE FACING THE CORE, TO FORM AN OVERLAPPED SEAM WHICH IS THEN HEATED TO BOND THE ADHESVIE ON THE ONE MAJOR SURFACE TO THE ADHESIVE ON THE OTHER MAJOR SURFACE. THE STRIP OF RELEASE AGENT MATERIAL MAY BE EASILY REMOVED TOGETHER WITH THE OVERLYING ADHESIVE TO BARE THE METAL TO FACILITATE GROUNDING AT A SPLICE LOCATION.
